Flyout palette customization [message #247677]

Hi all,

though I've sought the API, I couldn't find a way to customize a
GraphicalEditorWithFlyoutPalette's palette so that:
- I can set the layout of the palette
- the user cannot modify the palette at all except closing/opening it and
setting the large/small icons setting
What should I call or override?
I would also like to know when to call getPalettePrefences().setXXX()
correctly so that they take effect.

Thanks in advance,
thSoft

I'm partially there.
1. Customizing flyout preferences is best done (AFAIK) in
GraphicalEditorWithFlyoutPalette#cretePartControl, before calling the
super implementation.
2. I tried to customize palette viewer preferences by creating a subclass
of PaletteViewerProvider whose configurePaletteViewer does the preference
setting. However, I got the following exception:

Is this a bug, or am I doing something wrong?

I solved it: you have to create another PaletteViewerPreferences with your
own plugin's preference store, and set it as your palette viewer's
preferences.
