Creating a Flex AIR Annotator app: Part 49

In this tutorial we will add 2 more features to our application - the ability to drag items from the desktop into the application icon, launching the application and the dragged file already opened (if it is a picture), and the ability to paste images using Ctrl+V.

First we'll do the drag-to-launch-icon feature. To make this happen, we'll have to add an InvokeEvent.INVOKE event listener, which catches invoke events that are dispatched when the application is launched. This may happen more than once, for example, if the application is still running and the user launches it again.

private function listeners():void {
NativeApplication.nativeApplication.addEventListener(InvokeEvent.INVOKE, onInvoke);
addEventListener(MouseEvent.MOUSE_UP, drawUp);
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDown);
stage.addEventListener(KeyboardEvent.KEY_UP, keyUp);
addEventListener(Event.ENTER_FRAME, everyFrame);
this.addEventListener(NativeDragEvent.NATIVE_DRAG_ENTER, onDragIn);
this.addEventListener(NativeDragEvent.NATIVE_DRAG_DROP, onDrop);
PopUpManager.addPopUp(imageWindow, this, true);
PopUpManager.centerPopUp(imageWindow);
PopUpManager.removePopUp(imageWindow);
}

The InvokeEvent object has arguments property, which is an array. It may or may not be empty, it depends on how the application was launched. For example, if we launch it by dragging a file into the launch icon, it has the file's path in the arguments array.

So, we check if the first element of the arguments array exists, then we check if it represents a file path of a file that exists, and then we check for extension. If it is a picture, check which stack's selectedIndex it is and call the approporiate importDropImage() or addDropImage() method. This part of code is similar to the one in onDrop, with 2 exceptions.

The first one is that we add a break; command after alerting the error message. The second is that the addDropImage now has 2 parameters - the picture url, and the path that will be displayed in the path field:

private function onInvoke(evt:InvokeEvent):void {
var file:File;
if (evt.arguments[0]) {
file = new File(evt.arguments[0]);
if(file.exists){
switch (file.extension.toLowerCase()) {
case "jpg":
case "jpeg":
case "png":
case "gif":
if(stack.selectedIndex == 0){
importDropImage(file);
}
if(stack.selectedIndex == 1){
addDropImage(file.url, file.nativePath);
}
break;
default:
Alert.show("Unsupported file format.");
break;
}
}
}
}

Let's improve our existing onDrop() function now by adding an if statement that checks if the files array exists. Also update the line with addDropImage() by setting both parameters. Add a break; after the default code in the switch statement:

private function onDrop(evt:NativeDragEvent):void {
var files:Array = evt.clipboard.getData(ClipboardFormats.FILE_LIST_FORMAT) as Array;
if (files){
var file:File = files[0];
switch (file.extension.toLowerCase()) {
case "jpg":
case "jpeg":
case "png":
case "gif":
if(stack.selectedIndex == 0){
importDropImage(file);
}
if(stack.selectedIndex == 1){
addDropImage(file.url, file.nativePath);
}
break;
default:
Alert.show("Unsupported file format.");
break;
}
}
}

Here's what the addDropImage() function looks like with the two parameters, none of the logic was changed - its just that different values are now applied:

private function addDropImage(url:String, path:String = "Clipboard data"):void {
toolbarStack.selectedIndex = 1;
openImage();
imageWindow.validateNow();

var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComp);
loader.load(new URLRequest(url));

function loadComp(evt:Event):void {
iPreview.source = evt.target.content;
iPreviewHidden.source = evt.target.content;
iPath.text = path;
updatePreviewImage();
}
}

Now let's improve the existing importScreenshot() functionality. Right now, we can import pure bitmapdata objects. But what if we copied a picture from a browser? It doesn't copy the bitmapdata entirely, so it doesn't show right. It also puts the url of the file into the clipboard though. This is why we can check if there are both bitmapdata and url data available in the clipboard and just load the image from the url instead of using the bitmap data.

private function importScreenshot():void {
var hasUrl:Boolean = Clipboard.generalClipboard.hasFormat(ClipboardFormats.URL_FORMAT);
if (!hasUrl){
content = Clipboard.generalClipboard.getData(ClipboardFormats.BITMAP_FORMAT) as BitmapData;
bitmapData = Clipboard.generalClipboard.getData(ClipboardFormats.BITMAP_FORMAT) as BitmapData;
stackChange(); // needed if selectedIndex was already 1 when the function was called
stack.selectedIndex = 1;
}
if (hasUrl) {
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);
loader.load(new URLRequest(Clipboard.generalClipboard.getData(ClipboardFormats.URL_FORMAT)+""));
}
}

Now we'll do the Ctrl+V functionality, which pastes images into the application. This doesn't require much code, but is pretty complex, so pay attention.

First of all, there are two places in the application where the user can use Ctrl+V - that is the main screen with the 3 big buttons and the work area screen. If Ctrl+V is used on the main screen, then we should use the image to create a new project in our application entirely with it being the background. That is done using the importScreenshot() function.

If we use it on the working area screen, though, we need to check if the clipboard has both bitmapdata and url data (we don't do that with the main screen because importScreenshot() already checks that). If the clipboard has the url data, we call the addDropImage() function and pass the url data as the first parameter.

If there is no url found in the clipboard, we call a function called addBitmapImage, to which we pass the bitmap data.

So, in the beginning of the function we'll have 2 booleans that we use to tell whether there is bitmapdata and url data in the clipboard. Then, if the ctrl key is pressed, the v key is pressed and the clipboard contains bitmap data, it checks which screen currently is on. If it is the main screen, call importScreenshot. Otherwise, check if there is url in the clipboard and call addDropImage() or addBitmapImage() depending on the results:

private function keyDown(evt:KeyboardEvent):void {
var hasBitmap:Boolean = Clipboard.generalClipboard.hasFormat(ClipboardFormats.BITMAP_FORMAT);
var hasUrl:Boolean = Clipboard.generalClipboard.hasFormat(ClipboardFormats.URL_FORMAT);
if (evt.ctrlKey && evt.keyCode == 86 && hasBitmap) {
if (stack.selectedIndex == 0) {
importScreenshot();
}
if (stack.selectedIndex == 1) {
if (hasUrl) {
addDropImage(Clipboard.generalClipboard.getData(ClipboardFormats.URL_FORMAT) as String);
}
if (!hasUrl) {
addBitmapImage(Clipboard.generalClipboard.getData(ClipboardFormats.BITMAP_FORMAT) as BitmapData);
}
}
}
if (evt.keyCode == 16) {
isShift = true;
}
if (evt.keyCode == 17) {
isCtrl = 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();
}

The addBitmapImage() basically does the same as addDropImage(), but instead of using a loader, it uses a ready bitmap image with provided bitmap data:

private function addBitmapImage(bdata:BitmapData):void {
toolbarStack.selectedIndex = 1;
openImage();
imageWindow.validateNow();

iPreview.source = new Bitmap(bdata);
iPreviewHidden.source = new Bitmap(bdata);
iPath.text = "Clipboard data"
updatePreviewImage();
}

And we're done.
