Hello everyone. Please, anyone can guide me how to do this stuff.
I have a pannel and a box, The pannel is my component pannel(inside component pannel is eg. image, TextArea, Video) and Box is my target Box for my component creation. The user can select a component he/she want to create (dynamic creation) and drag it to target Box(drag and drop event). Then after creating the component the user can drag the component that he/she created and place anywhere on target Box and also the user can resize the component that he/she created(runtime resize).
i have this code for drag and drop and it seems this code works only on image
//-----action script-----//
private function dragIt(event:MouseEvent, value: String, objParent: String, objName: String):void
{
var dragInitiator:Image = event.currentTarget as Image;
var dragSource:DragSource = new DragSource();
dragSource.addData(value,'value');
dragSource.addData(objParent, 'parent');
dragSource.addData(objName, 'objname');
var dragProxy:Image = new Image();
dragProxy.source = event.currentTarget.source;
DragManager.doDrag(dragInitiator, dragSource, event, dragProxy);
}
private function dragEnterHandler(event:DragEvent):void
{
var dropTarget:Box=event.currentTarget as Box;
dropTarget.setStyle("borderThickness", 5);
DragManager.acceptDragDrop(dropTarget);
}
private function dragExitHandler(event:DragEvent):void
{
var dropTarget:Box=event.currentTarget as Box;
revertBoxBorder();
}
private function revertBoxBorder():void
{
targetBox.setStyle("borderThickness", 1);
}
private function dragDropHandler(event:DragEvent):void
{
var value:String = event.dragSource.dataForFormat('value') as String;
var objParent:String = event.dragSource.dataForFormat('parent') as String;
if(value == "mp3")
{
//do something
}
else if (value == "image")
{
if (objParent == "panel")
{
var imgView: Image = new Image;
imgView.x = event.stageX;
imgView.y = event.stageY;
addChild(imgView);
imgView.name = String(getChildByName(imgView.name).parent.numChildren-1);
imgView.addEventListener(MouseEvent.MOUSE_MOVE, function(e:MouseEvent):void
{
dragIt(e, value, 'box', Image(e.target).name);
});
imgView.source = ImgInsert;
}
else
{
var objName:String = event.dragSource.dataForFormat('objname') as String;
getChildByName(objName).parent.getChildAt(int(objName)).x = event.stageX;
getChildByName(objName).parent.getChildAt(int(objName)).y = event.stageY;
}
}
else if (value == "textarea")
{
//do something
}
}
//-----mxml code------//

How to move thus non image component like TxtArea? How to resize the component inside target box? (This is like GUI of flex when creating component) Thank you..
