Hi,
I am trying to write a MultiPageEditor, and I want to have a different
Palette for each Editor Page. It seems GEF only supports one Palette per
EditDomain, so what is the best way to make this work?
Thanks,

In my editor there`s only the control group with a panningselection Tool=

first.
You can add and remove and edit other palette drawer during runtime via =
=
the customizer.
But if i understand you right you have two different static palettes.
You can simply add and remove different PaletteDrawers or GroupElements =
=
with different tools via a PaletteManager object.
Something like this:
if(page1 acive)
PaletteManager.setPage1Palette(root);
else
PaletteManager.setPage2Palette(root);
Make sure to remove the other drawer/groups first in the setPageXPalettt=
e =
methods.
In PaletteManager you have the folowing methods:
public static void setPage1Palette(PaletteRoot root){
root.removeAllEntries();
root.add(createPalette1());
}
public static void removeAllEntries(PaletteRoot root){
List entries =3D root.getChildren();
for(int i=3D0; i<entries.size();++i){
root.remove((PaletteEntry)entries.get(i));
}
}
you sould alread have the createPaletteX() methods....
For more explanation on this search this newsgroup for "customize palett=
e" =
or something like that

Unfortunately it doesn't work too well, removing all entries from the

two, but still, my tools become inactive when I switch tabs. I changed the
removeAllEntries to this code:
protected static void removeAllEntries(PaletteRoot root)
{
// get a live list of children
List entries = root.getChildren();
// marks the default entry as null, otherwise it causes exceptin
// when removed.
root.setDefaultEntry(null);
// remove the first element until nothing's left
while (entries.size() > 0 )
{
root.remove((PaletteEntry) entries.get(0));
}
}
on the first page, it works, on the second page, I can't drag anything on
the editor (no parking icon). It works when used as flyout, but not as a
view.
What am I missing? There is no exception thrown.
Thanks,
David

viewer), which would then requery the editor for its palettepage. I
think...

How can the palette page switch page? That logic is in the palette view
class.
About the hack, we tried something similar (just notify the palette view),
but the palette reverted to the wrong appearance while dragging a tool to
the editor, not sure why, clicking on the tool itself switched page on the
palette.
So now I tried the other solution provided in the thread, and I'm still
having problems...
Thanks,

Ah, sorry. I seem to have circumvented that in my editor.
I left the default selection tool in the palette.
I have
public static void removeAllEntries(PaletteRoot root){
List entries =3D root.getChildren();
for(int i=3D 1 /*<<<!!!*/ ; i<entries.size();++i){
root.remove((PaletteEntry)entries.get(i));
}
}
as the removeAll method, leaving the control group (which is the first =
child of the root)
with the (default)selection tool always on the palette.
So that i never had those problems.
As for why it works in the second page as a flyout but not as a view i =
have no idea...

That's not so simple, first the Workbench won't notify anybody if the active
part is the one you try to simulate an activation for, so you have to notify
the PaletteView directly. Then the PaletteView will always try to refresh
its PalettePage when any part is activated (itself for instance). And the
PaletteView maintains a hashtable of Editor/PalettePage, so when it gets the
PalettePage once for the MultiPageEditor, it won't ask again.
So the first thing to do is to flush the PaletteView, with partClosed(), and
then notify it with partActivated. Here is how I did it in the MPE:
protected void pageChange(int newPageIndex)
{
super.pageChange(newPageIndex);
IViewPart paletteView =
this.getSite().getPage().findViewReference(PaletteView.ID).g etView(false);
if ( paletteView != null )
{
((PaletteView)paletteView).partClosed(this);
((PaletteView)paletteView).partActivated(this);
}
}
It seems to work, but this is really ugly, so if anybody has a better
solution, I'll gladly take it. I couldn't make the changes to PaletteRoot
work, even by keeping the default tool in it, I guess the PaletteRoot
doesn't support very well add/remove operations on the fly.
Thanks,
David
