Problem with repaint() [message #231036] Mon, 26 February 2007 13:20 Go to next message

Hello everyone,

I got a problem refreshing the visuals for my editor view. After
deleting objects, that are represented as single figures drawn on a
freeform-layer, the figure stays on the layer.
In the refreshVisuals() I do call getFigure.repaint().
I can use the delete() Action in the context-menue, . The figure gets
removed only if I click it again, or the Figure gets out of bounds (on
the screen)- I am quite sure that this is a really silly bug, but I just
can not get a finger on the spot.
Help is very appreciated!

Cheers

Oliver

I cannot say what might be wrong if I don't see your code.
In my simple editor I've got:
protected void refreshVisuals() {
		Rectangle bounds = new Rectangle(getCastedModel().getLocation(),
				getCastedModel().getSize());
		((GraphicalEditPart) getParent()).setLayoutConstraint(this,
				getFigure(), bounds);
		super.refreshVisuals();
	}

So as you see I don't invoke the repaint method anywhere.

Hope this helps :)

Hi Jakub,

thanks for your quick answer. I checked it, but it doesn't work this
way. I am using a freeformlayer, I did not implement the getLocation()
for the objects, because I am using a NodeLayouter. No XYLayout. The
Objects are positioned according their position in the tree.
Somehow I have to mark the part were the figure is painted as dirty, but
I do not know how.
Thanks again.

Cheers
Oliver

Hello Everyone,

I still haven't worked out the problem. At least now I am able to update
the window, but only after I click a second time (after deleting the
object)- Does anyone know why the window is not updated after I gave the
command, but after the second mouse-click?


cheers

Oliver

Hi everyone,

for those who wondered what the problem was. The layout manager
"DirectedGraphLayout" did not finish his work, and therefor the window
was not updated instantly. Well I do not really know why it worked after
I clicked the mouse again, but there you go.

Cheers

Oliver
