Creating a Flex AIR Annotator app: Part 44

Today we'll improve the functionality of our application by adding more features.

The features include saving annotation width value (without resetting it to 200 every time the user creates a new one), make annotations resizable in width using mouse, make it possible to copy color code by using the color picker and holding shift, make it possible to change depths of annotations by putting the selected one on top of others.

To do the width saving feature, we'll need to set the width to deafult (200) only once - for the first time. To know if it is the first time, we'll use a flag variable firstTimeEditing, declare it:

private var firstTimeEditing:Boolean = true;

Now in openAnnotation() function check if firstTimeEditing is true before setting annWidth's value to 200. Set it to false after that.

private function openAnnotation(createX:Number = 0, createY:Number = 0):void {
if(toolbarStack.selectedIndex==3){
PopUpManager.addPopUp(annotationWindow, this, true);
PopUpManager.centerPopUp(annotationWindow);
annText.text = "Enter text here";
annotationWindow.title = "Create new annotation";
annWidth.maximum = drawArea.width;
if (firstTimeEditing) annWidth.value = 200;
firstTimeEditing = false;
annX.value = createX;
annY.value = createY;
updateAnnCoordLimits();
baNew.enabled = true;
baEdit.enabled = false;
baDelete.enabled = false;
}
}

For the color picker part, go to getPickerColor() function and check if shift is held using the isShift variable, access clipboard by creating a Clipboard object and use its setData() method to save the color code:

private function getPickerColor():void {
lineColor = temporaryBitmap.getPixel(drawArea.mouseX, drawArea.mouseY);
if (isShift) {
var myClip:Clipboard = Clipboard.generalClipboard;
myClip.setData(ClipboardFormats.TEXT_FORMAT, "#" + lineColor.toString(16));
}
}

Now, the most complex feature for today - resizing annotations' width using mouse anchors. While doing this, we will also make the last feature I've mentioned above - giving the ability to change annotations' depth.

To make the annotations resizable like images, but not the same, we will copy and paste multple functions and rename them.

Declare new variables:

private var annAnchors:Array;
private var ann_currentDir:String = "";
private var ann_anchorX:Number;
private var ann_resizing:Boolean;
private var ann_positions:Array;

Now go to annOver() function and inside of it set currentAnn to evt.currentTarget, as well as call 3 functions - createAnnAnchors(), enableAnnResize() and positionAnnResize():

private function annOver(evt:MouseEvent):void {
disableResize();
if (toolbarStack.selectedIndex == 3) {
evt.target.alpha = 0.8;
currentAnn = evt.currentTarget;
createAnnAnchors();
enableAnnResize();
positionAnnResize();
}
}

Go to "stack" ViewStack container and add a new Group object called anchorsAnn. Also set the annHitArea's second rollover event handler to disableAnnResize():

<mx:ViewStack id="stack" change="stackChange();">
<s:NavigatorContent>
<s:HGroup gap="0">
<custom:BigButton icon="@Embed('../lib/folder.png')" subtext="Import picture" toolTip="Open file" enabled="true" buttonMode="true" bWidth="200" bHeight="200" click="importPicture();" />
<custom:BigButton icon="@Embed('../lib/blank.png')" subtext="Create blank" toolTip="Blank page" enabled="true" buttonMode="true" bWidth="200" bHeight="200" click="newFile(); newfileStack.selectedIndex = 1; newfileWindow.height = 160;" />
</s:HGroup>
</s:NavigatorContent>
<s:NavigatorContent>
<mx:Image id="imgHolder" />
<s:Group id="drawGroup">
<mx:Image id="drawBitmap" />
<s:Group id="tempSprite" />
</s:Group>
<mx:Box id="annHitArea" alpha="0" backgroundColor="#000000" click="openAnnotation(drawArea.mouseX, drawArea.mouseY);" rollOver="disableResize(); disableAnnResize();"/>
<s:Group id="images" />
<s:Group id="annotations" />
<s:Group id="cropDraw" mouseEnabled="false" />
<s:Group id="anchors"/>
<s:Group id="anchorsAnn"/>
<mx:Box id="drawHitArea" alpha="0" backgroundColor="#000000" mouseDown="drawDown();" mouseMove="drawMove();"/>
</s:NavigatorContent>
</mx:ViewStack>

Now we'll create functions that will be responsible for making the annotation resizable. They are all similar to functions we used for resizing images.

First one - createAnnAnchors(). Here we check if anchors have been created by checking if the annAnchor array is null. If so, add 2 anchors and set roll over, roll out and mouse down event listeners..

private function createAnnAnchors():void {
if (annAnchors == null) {
annAnchors = [];
for (var i:int = 0; i < 2; i++) {
var newAnchor:SpriteVisualElement = new SpriteVisualElement();
newAnchor.width = 10;
newAnchor.height = 10;
newAnchor.graphics.lineStyle(2, 0x000000);
newAnchor.graphics.beginFill(0xffffff);
newAnchor.graphics.drawRect(0, 0, 10, 10);
anchorsAnn.addElement(newAnchor);
annAnchors.push(newAnchor);
newAnchor.addEventListener(MouseEvent.ROLL_OVER, anchorAnnOver);
newAnchor.addEventListener(MouseEvent.ROLL_OUT, anchorAnnOut);
newAnchor.addEventListener(MouseEvent.MOUSE_DOWN, anchorAnnDown);
}
}
/* Layout:
- - -
0 - 1
- - -*/
}

The first two event handlers are anchorAnnOver() and anchorAnnOut():

private function anchorAnnOver(evt:MouseEvent):void {
if(anchorsAnn.alpha>0){
cursorManager.setCursor(resizeHorizontalCursor, 2, -9, -10);
}
}

private function anchorAnnOut(evt:MouseEvent):void {
cursorManager.removeAllCursors();
}

The anchorAnnDown() function sets ann_positions array's values to the x coordinate and width (2 elements total). Then it sets ann_currentDir to needed value, and gives a value for ann_anchorX in calculation using currentAnn's x coordinate and width. After that ann_resizing is set to true, and drawHitArea is enabled.

private function anchorAnnDown(evt:MouseEvent):void {
ann_positions = [currentAnn.x, currentAnn.width];
switch(evt.currentTarget) {
case annAnchors[0]: ann_currentDir = "left"; ann_anchorX = currentAnn.x + currentAnn.width; break;
case annAnchors[1]: ann_currentDir = "right"; ann_anchorX = currentAnn.x; break;
}
ann_resizing = true;
drawHitArea.mouseEnabled = true;
drawHitArea.width = content.width;
drawHitArea.height = content.height;
drawHitArea.x = -1;
drawHitArea.y = 1;
}

Next function - annResize(). Here we check if ann_resizing is true, check what direction the annotation is being resized and set ann_positions values. Call updateAnn() and positionAnnResize() if the annotation does not go off the borders:

private function annResize():void {
if (ann_resizing) {
cursorManager.removeAllCursors();
var mouseX:Number = drawArea.mouseX;
if (ann_currentDir == "left" && mouseX >= 0 && mouseX < ann_anchorX) {
ann_positions = [mouseX, ann_anchorX - mouseX];
cursorManager.setCursor(resizeHorizontalCursor, 2, -9, -10);
}
if (ann_currentDir == "right" && mouseX < content.width && mouseX > ann_anchorX) {
ann_positions = [ann_anchorX, mouseX - ann_anchorX];
cursorManager.setCursor(resizeHorizontalCursor, 2, -9, -10);
}

if(ann_positions[0] >=0 && ann_positions[1] + ann_positions[0]<=content.width){
updateAnn();
positionAnnResize();
}
}
}

The updateAnn() function updates x axis coordinate and width of currently selected annotation using the values from ann_positions array. Then we set annWidth's value to this width and call updateAnnCoordLimits.

private function updateAnn():void {
currentAnn.x = ann_positions[0];
currentAnn.width = ann_positions[1];
currentAnn.heightInLines = NaN;
annWidth.value = currentAnn.width;
updateAnnCoordLimits();
}

In enableAnnResize() function, we set alpha of anchorsAnn group to 0.8 and enable mouse:

private function enableAnnResize():void {
anchorsAnn.alpha = 0.8;
anchorsAnn.mouseEnabled = true;
anchorsAnn.mouseChildren = true;
}

In disableAnnResize(), we do the opposite:

private function disableAnnResize():void {
if(toolbarStack.selectedIndex==3 && !ann_resizing){
anchorsAnn.alpha = 0;
anchorsAnn.mouseEnabled = false;
anchorsAnn.mouseChildren = false;
}
}

Finally, we set proper annAnchors coordinates in the positionAnnResize() function:

private function positionAnnResize():void {
currentAnn.heightInLines = NaN;
var cX:Number = currentAnn.x;
var cY:Number = currentAnn.y;
var cW:Number = currentAnn.width;
var cH:Number = currentAnn.height;
annAnchors[0].x = cX - 5;
annAnchors[0].y = cY + cH/2 - 5;
annAnchors[1].x = cX + cW - 5;
annAnchors[1].y = cY + cH/2 - 5;
}

Go to drawMove() function and call annResize() there:

// annotation resizing
annResize();

In that same function, find the final conditional and add a new conditional inside of it, checking if selected index of toolbarStack is 3 - call positionAnnResize() if true:

if ((toolbarStack.selectedIndex == 3 || toolbarStack.selectedIndex == 1) && currentlyDragging != null) {
var nextDragX:Number = drawArea.mouseX - dragOffsetX;
var nextDragY:Number = drawArea.mouseY - dragOffsetY;
if (nextDragX >= 0 && nextDragX + currentlyDragging.width <= content.width) currentlyDragging.x = nextDragX;
if (nextDragY >= 0 && nextDragY + currentlyDragging.height <= content.height) currentlyDragging.y = nextDragY;
if (nextDragX < 0) currentlyDragging.x = 0;
if (nextDragY < 0) currentlyDragging.y = 0;
if (nextDragX + currentlyDragging.width > content.width) currentlyDragging.x = content.width - currentlyDragging.width;
if (nextDragY + currentlyDragging.height > content.height) currentlyDragging.y = content.height - currentlyDragging.height;
if (toolbarStack.selectedIndex == 1) positionResize();
if (toolbarStack.selectedIndex == 3) positionAnnResize();
}

In drawUp() function, set ann_resizing to false:

ann_resizing = false;

Now go to annMove() function and add a line that sets depth of annotations, moving the selected annotation on top of the rest:

private function annMove(evt:MouseEvent):void {
if (toolbarStack.selectedIndex == 3 && currentlyDragging && !drawHitArea.mouseEnabled) {
annotations.setElementIndex(currentlyDragging, annotations.numElements - 1);
cursorManager.setCursor(moveCursor, 2, -10, -10);
drawHitArea.mouseEnabled = true;
drawHitArea.x = -1;
drawHitArea.y = 0;
drawHitArea.width = content.width;
drawHitArea.height = content.height;
}
}

And we're done.
