Open a New Tab

I probably use this little tip at least 30 times a day!!! How to quickly open a new tab in your internet browser!

For those of you who are a fan of my Thursday Tips, I am sorry to say t hat this is the last one I can think of! However, this does leave me some time to start a new regular feature: Fonts on the First! Stay tuned this Monday, April 1st for my first collection of seasonal fonts for personal and commercial use!

C Program to check whether a number is odd or even

#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
int a;
cout<<"enter the number:";
cin>>a;

if(a%2==0)
cout<<"
Even number";
else
cout<<"
Odd number";
getch();
}

Introduction to WEKA GUI Chooser Basic Layouts Explained Are you bored of lengthy paragraphs of doucments A quick write up

Hi Guys,

This post will teach you basic layout structure of WEKA and in upcoming posts with examples.

Read my other article on how to download and install WEKA in Cent OS here

Documentation:
You can refer for the official documentation here : Click Here.
Alternatively you can find the pdf documentation in your WEKA installation :
Path : <WEKA installation folder>/weka-3-6-11/WekaManual.pdf

The official documentation gives you the clear & in depth details though Id like to share in my words how the layout looks like.

1) Once you launch the WEKA, the window opens with 4 different options which are 4 different applications with in WEKA.

2) The 4 Applications are
     i) Explorer
    ii) Experimentor
    iii) Knowledge Flow and
   iv) Simple CLI

3) Also, the window has Menu contains options "Programs", "Visualization","Tools" & "Help".

4)

Explorer An environment for exploring data with WEKA

Experimenter An environment for performing experiments and conduct-
ing statistical tests between learning schemes.

KnowledgeFlow An environment supports essentially the same func-
tions as the Explorer but with a drag-and-drop interface. One advantage
is that it supports incremental learning.

SimpleCLI Provides a simple command-line interface that allows direct
execution of WEKA commands for operating systems that do not provide
their own command line interface.

Thank you... Next post with some other basics on DataMining & with a simple example...

Installing Python with gdal on a Windows computer

Getting a new computer gave me the chance to try again installing Python with gdal. There may be various ways, but this works for me. It can be a bit tricky to get all working, so these resources helped me a lot:

My Computer: Windows 7, 64-bit

1) Download and install Python 2.7 (the 3er versions do not support all libraries yet (?) and my code is all 2.7)

2) For installing gdal I follow these instructions. This installs both the command line gdal utilities and the python bindings to use gdal within python. I need the command line utilities also to call them with "os.system" from within python.

[A day later I realize -- the bindings from the above mentioned webpage link the command line installation to python. For some reason in my new computer I dont get this to work. Solving that quickly and being lazy: Install the Python gdal bindings from the link at point 3 below. The difference is that these bindings contain the whole gdal. BUT if you only install these, you wont have the command line utilities available]

3) At this great page, "all" libraries are available in different version, especially Windows 64-bit:
I use it for installing additional libraries like Numpy, Pil, etc

4) I use Spyder for writing code (looks a bit like Matlab and works really great!). First install the Python GUI library "PyQt 4" from http://www.riverbankcomputing.com/software/pyqt/download and then Spyder, available here https://code.google.com/p/spyderlib/ or at http://www.lfd.uci.edu/~gohlke/pythonlibs/

[today, 1/3/2013, the 4.10 PyQt version had an issue with Spyder but that should be resolved soon in the download]

Creating a Flex AIR text editor Part 25

In this tutorial we will start working on another element of the interface which will count and enumerate lines in the text area.

This is what it is going to look like:

The column is a text field of a fixed width (for now), which is populated by characters by first checking how many lines there are in total and how many lines are displayed in the counter right now. If these two values are different, then we need to update the line enumeration - recount the lines and repopulate the text field.

This text field should also have the same font and size as the main text area, so that the lines match.

Another important thing is that we have to make it possible to toggle this line counter bar through the native menu, moreover, the bar will only be visible when the word wrapping is turned off. When wrapping is on, there are no lines and no columns in the text, so we dont really have anything to show.

By the end of this tutorial we will have a working, save-able and load-able line counting bar, which is updated when changing between tabs, when changing fonts, closing tabs, etc. However, it will not scroll and the width will be fixed, but these things will be improved in the next part.

Lets declare the new variables that we will be using in this part.

[Bindable]
private var pref_linecount:Boolean = true;

[Bindable]
private var textX:Number;

[Bindable]
private var tabWidth:Number;

[Bindable]
private var lineCountWidth:Number = 40;
[Bindable]
private var lineNumbers:String = "1";
[Bindable]
private var lineDisplayedNum:int = 1;

The pref_linecount variable is needed to toggle the bar. The textX variable didnt exist before, because the x was always 0. Because it will not be so from now on, we need to include this variable. We used textWidth for tabBar width before, now we will use tabWidth, because the width of the tabbar and textarea will not always be the same.

The lineCountWidth variable is the fixed width of the text area. The lineNumbers variable stores the text value for the bar text area. The lineDisplayedNum is a number that represents the number of lines that are shown on the bar right now.

First lets add the native menu item for toggling the pref_linecount variable and manage saving it and loading it. The procedure is already familiar to us. First add it to the XML:

<fx:XML id="windowMenu">
<root>
<menuitem label="File">
<menuitem label="New" key="n" controlKey="true" />
<menuitem label="Open" key="o" controlKey="true" />
</menuitem>
<menuitem label="Edit">
<menuitem label="Cut" key="x" controlKey="true" />
<menuitem label="Copy" key="c" controlKey="true" />
<menuitem label="Paste" key="v" controlKey="true" />
<menuitem type="separator"/>
<menuitem label="Select all" key="a" controlKey="true" />
</menuitem>
<menuitem label="Settings">
<menuitem label="Word wrap" type="check" toggled="{pref_wrap}" />
<menuitem label="Font..."/>
</menuitem>
<menuitem label="View">
<menuitem label="Tool bar" type="check" toggled="{pref_toolbar}" />
<menuitem label="Status bar" type="check" toggled="{pref_status}" />
<menuitem label="Line count" type="check" toggled="{pref_linecount}" />
<menuitem label="Side pane" type="check" toggled="{pref_sidepane}" />
</menuitem>
</root>
</fx:XML>

Now update the preferences part in the init function.

Note 1: the wrap and linecount variables must be different by default.

Note 2: the first time running this code you will need to include "preferences.data.firsttime = null;" to reset the shared object.

// Set preferences if loaded for the first time
if (preferences.data.firsttime == null) {
preferences.data.firsttime = true;
preferences.data.wrap = false;
preferences.data.status = true;
preferences.data.toolbar = true;
preferences.data.sidepane = true;
preferences.data.linecount = true;
preferences.data.fontsettings = {fontfamily:"Lucida Console", fontsize:14, fontstyle:"normal", fontweight:"normal", fontcolor:0x000000, bgcolor:0xffffff};
preferences.flush();
}

// Set preferences loaded from local storage
pref_wrap = preferences.data.wrap;
pref_status = preferences.data.status;
pref_toolbar = preferences.data.toolbar;
pref_sidepane = preferences.data.sidepane;
pref_fontsettings = preferences.data.fontsettings;
pref_linecount = preferences.data.linecount;

Add this line to the menuSelect function:

(evt.item.@label == "Line count")?(pref_linecount = !pref_linecount):(void);

Update savePreferences():

private function savePreferences():void {
preferences.data.wrap = pref_wrap;
preferences.data.status = pref_status;
preferences.data.toolbar = pref_toolbar;
preferences.data.fontsettings = pref_fontsettings;
preferences.data.sidepane = pref_sidepane;
preferences.data.linecount = pref_linecount;
preferences.flush();
}

Now lets update the menuSelect function again - lets add a conditional which checks if pref_wrap is true. If it is, set linecount to false.

Also, call countLines() function (well create it later in the tutorial):

private function menuSelect(evt:FlexNativeMenuEvent):void {
(evt.item.@label == "New")?(doNew()):(void);
(evt.item.@label == "Word wrap")?(pref_wrap = !pref_wrap):(void);
(evt.item.@label == "Cut")?(doCut()):(void);
(evt.item.@label == "Copy")?(doCopy()):(void);
(evt.item.@label == "Paste")?(doPaste()):(void);
(evt.item.@label == "Select all")?(doSelectall()):(void);
(evt.item.@label == "Status bar")?(pref_status = !pref_status):(void);
(evt.item.@label == "Tool bar")?(pref_toolbar = !pref_toolbar):(void);
(evt.item.@label == "Side pane")?(pref_sidepane = !pref_sidepane):(void);
(evt.item.@label == "Line count")?(pref_linecount = !pref_linecount):(void);
(evt.item.@label == "Font...")?(doFont()):(void);
savePreferences();
updateStatus();
if (pref_wrap) {
pref_linecount = false;
}
updateTextSize();
countLines();
}

The countLines() function will be used to update the bar. We need to call it every time we change the value of the text area.

Now, lets update the updateTextSize() function. We need to manage the new textX variable, update the textWidth variable and manage tabWidth. The function after the changes:

private function menuSelect(evt:FlexNativeMenuEvent):void {
(evt.item.@label == "New")?(doNew()):(void);
(evt.item.@label == "Word wrap")?(pref_wrap = !pref_wrap):(void);
(evt.item.@label == "Cut")?(doCut()):(void);
(evt.item.@label == "Copy")?(doCopy()):(void);
(evt.item.@label == "Paste")?(doPaste()):(void);
(evt.item.@label == "Select all")?(doSelectall()):(void);
(evt.item.@label == "Status bar")?(pref_status = !pref_status):(void);
(evt.item.@label == "Tool bar")?(pref_toolbar = !pref_toolbar):(void);
(evt.item.@label == "Side pane")?(pref_sidepane = !pref_sidepane):(void);
(evt.item.@label == "Line count")?(pref_linecount = !pref_linecount):(void);
(evt.item.@label == "Font...")?(doFont()):(void);
savePreferences();
updateStatus();
if (pref_wrap) {
pref_linecount = false;
}
updateTextSize();
countLines();
}

Go to the removeTab() function and call the countLines() function in the end (while were at it):

private function removeTab(index:int):void {
// if this is the last tab, create a new empty tab
if (tabData.length == 1) {
tabData.addItem( { title:"Untitled", textData:"", saved:false } );
}
statusMessage = "[ " + new Date().toLocaleTimeString() + " ] Tab closed: " + tabData[index].title;
updateStatus();
tabData.removeItemAt(index);
tabSelectedIndex = tabBar.selectedIndex;
previousIndex = tabSelectedIndex;
textArea.text = tabData[tabSelectedIndex].textData;
textArea.selectRange(tabData[tabSelectedIndex].selectedAnchor, tabData[tabSelectedIndex].selectedActive);
if (closeAfterConfirm && tabsToClose == 0) {
FlexGlobals.topLevelApplication.close();
}
countLines();
}

Now lets create the text area bar as a component.

First update the textArea text area so that it calls the countLines() function on change event plus what we already have, and set its x property to textX:

<s:TextArea id="textArea" width="{textWidth}" height="{textHeight}" y="{textY}" x="{textX}" borderVisible="false" lineBreak="{(pref_wrap)?(toFit):(explicit)}"  click="cursorFix(); updateStatus();" change="updateStatus(); countLines();" keyDown="updateStatus();"/>

Now update the tabbar by settings its width to tabWidth instead of textWidth:

<custom:CustomTabBar id="tabBar" dataProvider="{tabData}" width="{tabWidth}" y="{tabY}" itemRenderer="CustomTab" height="22" tabClose="onTabClose(event);" change="tabChange(tabbar);" selectedIndex="{tabSelectedIndex}"/>

Create a new TextArea object, give it an id of lineCount. Set its width to lineCountWidth, text to lineNumbers, visible to pref_linecount, height to textHeight, y to textY, editable, selectable and mouseEnabled to false and textAlign to right.

<s:TextArea id="lineCount" width="{lineCountWidth}" text="{lineNumbers}" visible="{pref_linecount}" height="{textHeight}" y="{textY}" editable="false" selectable="false" mouseEnabled="false" textAlign="right"/>

Now - the countLines function weve been talking about! Here we need to check if the linecount bar is toggled on and if word wrapping is off. If the conditions are met, count total lines and compare them to the lines currently displayed on the bar. If they do not match, recount and reenumerate the lines using a updateLineCount() function, which simply fills the text area with text:

private function countLines():void {
if (pref_linecount && !pref_wrap) {
var totalLines:int = textArea.text.split("
").length;
if (totalLines != lineDisplayedNum) {
updateLineCount(totalLines);
lineDisplayedNum = totalLines;
}
}
}

private function updateLineCount(total:int):void {
lineNumbers = "";
for (var i:int = 1; i < (total + 1); i++) {
lineNumbers += i + "
";
}
}

As I said before, we want the font settings to be the same in the textArea and in the lineCount area:

private function updateFonts():void{
textArea.setStyle("fontFamily", pref_fontsettings.fontfamily);
textArea.setStyle("fontSize", pref_fontsettings.fontsize);
textArea.setStyle("fontStyle", pref_fontsettings.fontstyle);
textArea.setStyle("fontWeight", pref_fontsettings.fontweight);
textArea.setStyle("color", pref_fontsettings.fontcolor);
textArea.setStyle("contentBackgroundColor", pref_fontsettings.bgcolor);

lineCount.setStyle("fontFamily", pref_fontsettings.fontfamily);
lineCount.setStyle("fontSize", pref_fontsettings.fontsize);
lineCount.setStyle("fontStyle", pref_fontsettings.fontstyle);
lineCount.setStyle("fontWeight", pref_fontsettings.fontweight);
lineCount.setStyle("color", pref_fontsettings.fontcolor);
lineCount.setStyle("contentBackgroundColor", pref_fontsettings.bgcolor);
}

Android beginner tutorial Part 2 Creating a project in Eclipse

Today well learn how to create Android projects in Eclipse.

Launch the Eclipse IDE with Android SDK built in. It will ask you to perform some one-time tasks, such as create a workspace on your hard drive.

When thats done, we can start creating our first application. To begin creating a new Android project, select File > New > Android Application Project.

A dialog box pops up, which requires us to fill out some of the general settings for our future application. The first field is called "Application Name". This is the title of your application - it appears as the name of your app in the Play Store, Manage Applications screen, etc.

The second field is called Project Name. Unlike Application Name, this isnt shown to anyone but the developer when using Eclipse. Usually, the Application Name and Project Name are the same.

The third field is called Package Name. This is basically the id of your application - usually its not shown to the user, but it is required to stay the same for all of the versions of your application. This is similar to ids in Adobe AIR descriptor files. The format is the same as packages in AS3, for example - com.kircode.codeforfood_test

Then we are required to select Minimum Required SDK. This is basically the Android version that is required to run your application. Keep in mind that the lower the version is, the bigger your audience is, but your application wont be able to use some of the newer SDK features. It is recommended to set this value to API 8, this way, according to Android development center, youre targeting 95% of the users. Thats good enough.

The next field is Target SDK. Set this to the highest API version that your application will run on. This value informs the system that the application has been tested on this API and is supposed to work without the sytem having to do any compatibility processes. If youre unsure what to select here, pick one of the modern versions - this way your application wont look dated and will still be compatible with older versions (up to Minimum Required SDK).

The next field is Compile With. This is the API version that the application will be compiled with. If the default value isnt the most recent version, its recommended to pick that.

And finally theres Theme. Pick the color theme that will suit your application. You will, of course, be able to customize every element of your application manually if you want, but choosing a Theme here is a good alternative too.

Hit next, and you should be taken to the next configuration step. Here youll see a few check boxes and fields. The first checkbox, "Create custom launcher icon", can be selected if you want to create a custom icon for your application. I do! So I always have this checked.

The next checkbox is "Create activity". Check this, because we want to generate ourselves an Activity. I will explain what an Activity is in details a bit later.

This isnt going to be a library, so dont check "Mark this project as a library". If you have "Create Project in Workspace" checked, the application project folder will be created in the workspace that you defined when you first launched Eclipse. If its unchecked, youll be able to set a custom location for your project. I think its nice to keep things organized and all development projects should be in the development workspace, so I leave this checked.

The next part consists of a checkbox and a selection menu. Its labeled as "Working sets" and the checkbox asks us if we want to add our project to a working set. Working sets are basically groups of projects that are displayed together in the menu when youre working on one of those projects. This is a useful feature and might come in handy when working on multiple applications of the same sort, or of the same purpose, or grouped together for some other reason. Right now we dont want to include our projects in any working sets.

Hit next. We can now set a Launcher Icon for our application. If you have an image ready for that, you can import it here. You can create a new icon using any of the preset clipart images or enter some text to act as an icon. You have several other tools in this window to style your icon.

Click next, and now were asked to choose what kind of activity we want to create. Now, simply put, an Activity is a window in Android. You probably know that there arent really any windows in Android at all, except for some dialog boxes, and thats true. But the way Activities behave are similar to windows in computer operating systems. For example, if we launch a game on Android, we are first taken to the main menu screen. This is an Activity. If we click "play", the game itself launches where we can actually play it. This is another Activity. It should be noted that if we didnt purposefully close the previous (main menu) activity when launching the game, it doesnt close. The main menu is still there, under the game, not visible to the user, just "sleeping" and waiting to be opened again.

The Activities have a complex life cycle, which I will explain in later tutorials. For now, you just need to understand that an Activity is a single screen that contains some content, it can be opened, paused, stopped, etc.

So right now were on the Create Activity screen, with 5 available activity types - BlankActivity, FullscreenActivity, LoginActivity, MasterDetailFlow and SettingsActivity. Think of these as of templates.

The BlankActivity is a blank page that we can fill with content.

The FullscreenActivity is a blank page also, but it hides all the UI elements of the device. This is probably most suited for games and video applications.

The LoginActivity is a simple template used for registering or logging in using email and password.

The MasterDetailFlow is a template that has a menu and a content area. It should be noted that the template is displayed differently on tablets and phones (it creates 2 columns on bigger screens where possible, and 1 column on smaller screens).

The SettingsActivity is a simple page with UI components lined up like in the settings screen of your device.

Pick BlankActivity and click Next.

Here we are asked to set the Activity Name, Layout Name and Navigation Type for our main Activity. Leave their values as they are by default - MainActivity, activity_main and None. The names are basically for the developer to remember which Activity is which. The Navigation Type dropdown box lets you select a default navigation method for your Activity. There are multiple nice and useful pre-set navigation features here, but well leave this field None for our first project.

Click Finish, wait, and youre done!

Well continue next time!

Creating a Flex AIR Annotator app Part 48

In the last tutorial we implemented an ability to draw zig zags using lines and arrows.

We made it possible using the lastX and lastY values that stored previous line/arrow end coordinates. They never reset, though, and if you undo or redo a line/arrow, the coordinates still remain the same.

To fix this, and synchronize previous line end coordinates with undo/redo flow, well need to create a new separate memory array that will store coordinate values. That doesnt mean well get rid of the lastX and lastY variables - we will still need them.

First of all, we need to declare this variable:

private var undo_lastPointsMemory:Array;

Now in stackChange() function, which is called when the project is opened, set this variables value to an empty array, also set lastX and lastY values to -1 here:

private function stackChange():void {
if (stack.selectedIndex == 1) {
imgHolder.source = new Bitmap(bitmapData);
drawArea.width = content.width;
drawArea.height = content.height;
drawGroup.width = content.width;
drawGroup.height = content.height;
cropDraw.width = content.width;
cropDraw.height = content.height;
eraser.width = content.width;
eraser.height = content.height;
buttonsEnabled = true;
clearDrawBitmap();
var anns:Number = annotations.numChildren;
for (var i:int = 0; i < anns; i++){
annotations.removeElementAt(0);
}
var imgs:Number = images.numChildren;
for (var u:int = 0; u < imgs; u++){
images.removeElementAt(0);
}
drawTempBitmap();
updateDrawHitArea();
crop_deselect();
undo_canRedo = false;
undo_canUndo = false;
undo_currentMemory = 0;
undo_memory = [];
undo_lastPointsMemory = [];
lastX = -1;
lastY = -1;
}
}

Set it empty in clearDrawBitmap() as well:

private function clearDrawBitmap():void {
undo_canRedo = false;
undo_canUndo = false;
undo_currentMemory = 0;
undo_memory = [];
undo_lastPointsMemory = [];
drawBitmap.source = new Bitmap(new BitmapData(content.width, content.height, true, 0x00ffffff));
lastX = -1;
lastY = -1;
}

Now go to addUndo() function and inside the two conditionals, do a similar procedure that is done with undo_memory array: in the first conditional, set its currently selected element to a new point with coordinates lastX and lastY. In the second conditional, shift() it and set its last elements value to a new point with lastX and lastY values.

private function addUndo(bd:BitmapData):void {
undo_canRedo = false;
if (undo_currentMemory < undo_memoryLimit - 1) {
undo_currentMemory++;
undo_memory[undo_currentMemory] = bd.clone();
undo_lastPointsMemory[undo_currentMemory] = new Point(lastX, lastY).clone();
undo_canUndo = true;
}else
if (undo_currentMemory == undo_memoryLimit - 1) {
undo_memory.shift();
undo_memory[undo_memoryLimit - 1] = bd.clone();
undo_lastPointsMemory.shift();
undo_lastPointsMemory[undo_memoryLimit - 1] = new Point(lastX, lastY).clone();
undo_canUndo = true;
}
}

Now in drawDown() function, find the isCtrl conditional (we have two, but they are the same) and change it to this:

if (isCtrl && undo_lastPointsMemory[undo_currentMemory] && undo_lastPointsMemory[undo_currentMemory].x>=0 && undo_lastPointsMemory[undo_currentMemory].y>=0) {
tempSprite.graphics.moveTo(undo_lastPointsMemory[undo_currentMemory].x, undo_lastPointsMemory[undo_currentMemory].y);
anchorX = undo_lastPointsMemory[undo_currentMemory].x;
anchorY = undo_lastPointsMemory[undo_currentMemory].y;
}else {
tempSprite.graphics.moveTo(drawArea.mouseX, drawArea.mouseY);
anchorX = drawArea.mouseX;
anchorY = drawArea.mouseY;
}

This checks if the currently selected element in the memory array actually exists and if its coordinates equal or are greater than 0. Then it sets values to the ones from the array instead of lastX and lastY.

if (isCtrl && undo_lastPointsMemory[undo_currentMemory] && undo_lastPointsMemory[undo_currentMemory].x>=0 && undo_lastPointsMemory[undo_currentMemory].y>=0) {
tempSprite.graphics.moveTo(undo_lastPointsMemory[undo_currentMemory].x, undo_lastPointsMemory[undo_currentMemory].y);
anchorX = undo_lastPointsMemory[undo_currentMemory].x;
anchorY = undo_lastPointsMemory[undo_currentMemory].y;
}else {
tempSprite.graphics.moveTo(drawArea.mouseX, drawArea.mouseY);
anchorX = drawArea.mouseX;
anchorY = drawArea.mouseY;
}

After updating the two if statements, the whole function looks like this:

private function drawDown():void {
// cropping
if(toolbarStack.selectedIndex == 4 && mouseY>60) crop_mouseDown(drawArea.mouseX, drawArea.mouseY);

// drawing
if (toolbarStack.selectedIndex == 2 && drawTools.selectedIndex == 0) {
drawMode = "pen";
tempSprite.graphics.clear();
tempSprite.graphics.moveTo(drawArea.mouseX, drawArea.mouseY);
cursorManager.removeAllCursors();
cursorManager.setCursor(emptyCursor, 2, -10, -10);
}
if (toolbarStack.selectedIndex == 2 && drawTools.selectedIndex == 3) {
drawMode = "line";
if (isCtrl && undo_lastPointsMemory[undo_currentMemory] && undo_lastPointsMemory[undo_currentMemory].x>=0 && undo_lastPointsMemory[undo_currentMemory].y>=0) {
tempSprite.graphics.moveTo(undo_lastPointsMemory[undo_currentMemory].x, undo_lastPointsMemory[undo_currentMemory].y);
anchorX = undo_lastPointsMemory[undo_currentMemory].x;
anchorY = undo_lastPointsMemory[undo_currentMemory].y;
}else {
tempSprite.graphics.moveTo(drawArea.mouseX, drawArea.mouseY);
anchorX = drawArea.mouseX;
anchorY = drawArea.mouseY;
}
cursorManager.removeAllCursors();
cursorManager.setCursor(emptyCursor, 2, -10, -10);
}
if (toolbarStack.selectedIndex == 2 && drawTools.selectedIndex == 2) {
drawMode = "rect";
anchorX = drawArea.mouseX;
anchorY = drawArea.mouseY;
}
if (toolbarStack.selectedIndex == 2 && drawTools.selectedIndex == 1) {
drawMode = "ellipse";
anchorX = drawArea.mouseX;
anchorY = drawArea.mouseY;
}
if (toolbarStack.selectedIndex == 2 && drawTools.selectedIndex == 4) {
drawMode = "arrow";
if (isCtrl && undo_lastPointsMemory[undo_currentMemory] && undo_lastPointsMemory[undo_currentMemory].x>=0 && undo_lastPointsMemory[undo_currentMemory].y>=0) {
tempSprite.graphics.moveTo(undo_lastPointsMemory[undo_currentMemory].x, undo_lastPointsMemory[undo_currentMemory].y);
anchorX = undo_lastPointsMemory[undo_currentMemory].x;
anchorY = undo_lastPointsMemory[undo_currentMemory].y;
}else {
tempSprite.graphics.moveTo(drawArea.mouseX, drawArea.mouseY);
anchorX = drawArea.mouseX;
anchorY = drawArea.mouseY;
}
cursorManager.removeAllCursors();
cursorManager.setCursor(emptyCursor, 2, -10, -10);
}
if (toolbarStack.selectedIndex == 2 && drawTools.selectedIndex == 5) {
drawMode = "picker";
drawTempBitmap();
getPickerColor();
}
}

And were done!
