Changing Palette [message #893926]

Hello,

I want to make a little change to the palette to show two tabs on the top. And each tab
shows different palette. I just can get the paletteViewer in my diagram editor.

getEditDomain().getPaletteViewer();

I also find PaletteDrawer, GraphicalEditorWithFlyoutPalette and so on,
but I still can't find out what is the right way to change the control or layout of the palette.

Any idea?

Thank you in advance.

Best Regards,
Jason

I'm now looking at DiagramEditorInternal and hope that the method createpaletteRoot can help me.

The editor API is not really in shape for doing things like that in Graphiti
0.8.2. We reworked it for our current release 0.9.0 as part of Juno, so you
should really have a look into that Graphiti version

Otherwise you are on the right track with that method, but as I said this
could get somewhat difficult in 0.8...

Thanks for your quick response.
I have tracked the codes hours and still can't find a excellent extend point to meet my requirement... I am considering whether change to another UI design which also can be accepted.
But because of cooperation with other components, I can't change to new release. Such a pity.

PS:You are always so nice and I have read lots of your replies and they help me so much. Best wishes.

Jason Lin.

I give up the tab UI. And try to add two buttons or components that can be selected.
Finially I add two dummy tool entries Sad

1. CreateProcedureDiagramEditor extends DiagramEditor implements ISelectionChangedListener

@Override
	protected PaletteRoot createPaletteRoot() {
		// TODO Auto-generated method stub
		platetteRoot = new MyGFPaletteRoot(getConfigurationProvider());
		return  platetteRoot;
	}

2. MyGFPaletteRoot extends PaletteRoot
add two dummy tool entry on the top when updatePaletteEntries

3. Add selection listener
PaletteViewer paletteViewer = getEditDomain().getPaletteViewer();
paletteViewer.addSelectionChangedListener(this);

Through the above codes, I can dynamically udpate the palette when selection change.
But it tastes bad and I have to deal with the original tool entry handling process.... Thus I am considering other solutions.

Any idea?

Best Regards,
Lin, Qinhe
