Palette View Refresh without open and close [message #241313]

Hello there,

Context:

I am using GEF Palette to dispaly the PaletteContainer and Palette
Items. And the canvas is actually not from GEF. I have my own model
which holds the data on how the Palette tree structure will be built.

I have a created an Eclipse View which contains my own Viewer (say
DesignerPaletteViewer) which extends
org.eclipse.gef.ui.palette.PaletteViewer

My model is returned by this code Object[] contributions =
PaletteCoreManager.getInstance().getContributions();
the contributions array contains all my contribution.

my createBasicPaletteControls() creates SelectionToolEntry (which get
loaded always)

I have the following method in DesignerPaletteViewer:

public void displayPalette() throws PaletteCoreException {
createBasicPaletteControls();
Object[] contributions =
PaletteCoreManager.getInstance().getContributions();
addPaletteContributions(contributions);
setPaletteRoot(paletteRoot);
this.setActiveTool(selectionTool);
}

My problem is when I run this code, it does not refresh the Viewer until
I close and open the Palette View in Eclipse manually. I may have some
WorkspaceJob running in the backgroud to load the model, once it is
loaded I want that the notifier updates the DesignerPaletteViewer
dynamically., which inturn displays my complete Palette Tree structure.

Is there a way to refresh the PaletteViewer?

I am using GEF 3.3.1

Thanks in Advance
Ranjeev

Not known your refresh efect, so guess check GEF PaletteView, which has
a perspective listener registered.
