Hi Jeethu,

Thanks for this example.

I am using this on a canvas. I have a few buttons embedded with images. I drag and drop them on to the canvas. Now i would like to be able to select these images as i like using the selectionRectangle. I have used your example successfully. I can see the number of items selected in the label.

But i want to see the borders of the button prominently visible when i select like for example, when i select two of the images that have been dropped, then their should appear small boxes on the edges of the borders of the selected buttons. How do i do that?

Thanks in advance

@Sai You might be nesting the selection rectangle within some container. That may be the problem

Hi!

Es ist zwar schon ein wenig her das du das hier reingestellt hast. Hätte da aber trotzdem ne Frage zu.
Habe mir das gerade mal angesehen. Wenn ich eine Ausgabe mache, welche Elemente ausgewählt wurden, schreibt er immer den Klassenamen davor.

Also z.B. Klassename.Button1

Sehe irgendwie nicht das du das programmiert hast. Ist das Standard in flex oder finde ich nur die Stelle im Code nicht.

Ich bräuchte dann ja den Namen des Objektes (ohne Klassenamen) damit ich dieses ansprechen kann. Zum Beispiel das es sich nach Rechts bewegen soll.

Kannst du mir da helfen? Oder jmd anders?
Danke

@Elan After the selection the selected items are available in the array called ’selectedItems’ as per my code. What you can do is, add these items to a container( a canvas maybe ) when the ‘group’ button is clicked on. The reverse applies for ‘ungroup’. Use the globalToLocal, localToGlobal, etc. functions to set the x and y of the items during both grouping and ungrouping… for a demo take a look at Stickies in Sync, http://blog.jeethukarthik.com/adobe-riathon-08/ .I built this app a long time ago….

Hi Jeethu,

Thanks for doing this. It’s amazing.

Just wondering 2 things.

1. How would I use it within a certain container? For example, another canvas. I tried changing the code from addChild(selectionRectangle) to canvas.addChild(selectionRectangle), however it doesn’t seem to be working. Any idea why?

2. I’d like for the selectionRectangle to remain on the stage until the next mouseDown (so that the user knows the area that he/she has selected). Is there a way that that could be implemented?

Thanks so much for everything. I’m still a beginner to Flex/AS3, so please forgive me if the answers to those questions seem obvious.

Legend. I wrote my own before finding this article, based on canvas as well, but missing one bit: I’ve been looking for this:

if(selectionRectangle.getRect(this).intersects((children[i] as DisplayObject).getRect(this)))

Cheers!

@arindam – The Rectangle class i’ve used above is only for reference. To obtain the width,height,x and y. The blue rectangle that appears is a Canvas. And btw try this link to do this in flash
