Creating a Flex AIR Annotator app: Part 39

In this tutorial we will create undo/redo functionality for shape drawing.

To start, let's create 5 variables with undo_ prefix:

[Bindable]
private var undo_canUndo:Boolean = false;
[Bindable]
private var undo_canRedo:Boolean = false;
private var undo_memory:Array;
private var undo_currentMemory:int;
private var undo_memoryLimit:int = 4;

The first two are booleans that will indicate when the undo and redo icons should be disabled or enabled. The third variable is an array that will hold previous bitmapdata objects. The fourth variable contains the value of the current memory item that is currently being displayed. The last variable holds value of how many BitmapData objects there can be in the array at the same time. Setting this value to 4 will mean that there will be 4 screens stored, and the user can rewind 3 steps backwards or forwards.

Now we need to add 2 buttons to the tools panel under the Drawing tool. Find the NavigatorContent that contains all the drawing related elements and add 2 SmallButton objects with icons set to arrow_undo.png and arrow_redo.png. Here are the images:



Set their enabled properties bound to undo_canUndo and undo_canRedo. Set their click event handlers to doUndo() and doRedo():

<s:NavigatorContent>
<s:VGroup width="100%" height="44" top="4">
<s:Label fontSize="18" color="#333333">Selected: Draw</s:Label>
<s:HGroup>
<custom:SmallButton icon="@Embed('../lib/arrow_undo.png')" enabled="{undo_canUndo}" click="doUndo();" />
<custom:SmallButton icon="@Embed('../lib/arrow_redo.png')" enabled="{undo_canRedo}" click="doRedo();" />
<mx:ToggleButtonBar dataProvider="{toolbarToggle}" width="130" id="drawTools" />
<mx:ColorPicker selectedColor="@{lineColor}" change="updateLineExample();" />
<mx:Slider minimum="1" maximum="10" change="updateLineExample();" value="@{lineThickness}" width="80" liveDragging="true"/>
<s:SpriteVisualElement width="40" height="20" id="lineExample"/>
<s:Button click="clearDrawBitmap();" label="Clear all" />
</s:HGroup>
</s:VGroup>
</s:NavigatorContent>

Next, we create 3 functions - addUndo(), doUndo() and doRedo(). The last 2 functions basically go one step backward or forward in memory, and the first one adds an item to the memory.

The addUndo() function should be called whenever a change is made to the bitmap data, and that is in the doDrawBitmap() function. Pass the bitmap data object as parameter when calling this function:

private function doDrawBitmap():void {
drawBitmap.width = content.width;
drawBitmap.height = content.height;
drawBitmap.validateNow();
var tempBd:BitmapData = new BitmapData(content.width, content.height, true, 0xff0000);
tempBd.draw(tempSprite, null, null, null, null, true);
var bd:BitmapData = new BitmapData(content.width, content.height, true, 0x00ff00);
bd.draw(drawBitmap, null, null, null, null, true);
bd.copyPixels(tempBd, new Rectangle(0, 0, content.width, content.height), new Point(0, 0), null, null, true);
drawBitmap.source = new Bitmap(bd, "auto", true);
addUndo(bd);
}

When the function is called, it sets canRedo to false and then checks, whether it should add new entries to the memory array, or shift all existing memory entries back and add a new one if the limit has been reached. Then it applies the bitmap data object to that index:

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

The doUndo() function decreases currentMemory by 1 and displays the bitmap data object that has this index:

private function doUndo():void {
undo_currentMemory--;
drawBitmap.source = new Bitmap(undo_memory[undo_currentMemory], "auto", true);
undo_canRedo = true;
if (undo_currentMemory > 0) undo_canUndo = true;
if (undo_currentMemory <= 0) undo_canUndo = false;
}

The doRedo() function does the same, but otherwise - increases currentMemory and applies that bitmap data.

private function doRedo():void {
undo_currentMemory++;
drawBitmap.source = new Bitmap(undo_memory[undo_currentMemory], "auto", true);
undo_canUndo = true;
if (undo_currentMemory < undo_memory.length-1) undo_canRedo = true;
if (undo_currentMemory >= undo_memory.length-1) undo_canRedo = false;
}

And we're basically done - we can undo and redo our drawings now. One thing is missing though - that is the Ctrl+Z and Ctrl+Y shortcuts that everyone is used to. We already have a function that responds to keyboard events - keyDown, so let's use that to add these shortcuts:

private function keyDown(evt:KeyboardEvent):void {
if (evt.keyCode == 16) {
isShift = true;
}
if (evt.ctrlKey && evt.keyCode == 90 && undo_canUndo && toolbarStack.selectedIndex == 2) doUndo();
if (evt.ctrlKey && evt.keyCode == 89 && undo_canRedo && toolbarStack.selectedIndex == 2) doRedo();
}

And now we're really done!
