Hello guys!
I have already searched this newsgroup how to disable a palette entry.
Seemingly it was not possible in former versions of GEF. Is it planned
to implement this functionality in future releases?
Kind regards,
Robert

look into the ToolEntryEditPart, locate at the method createFigure,
you'll see this:
public IFigure createFigure() {
class InactiveToggleButton extends ToggleButton {
InactiveToggleButton(IFigure contents) {
super(contents);
setOpaque(false);
setEnabled(true);
}
public IFigure findMouseEventTargetAt(int x, int y) {
return null;
}
public IFigure getToolTip() {
return createToolTip();
}
public void setEnabled(boolean value) {
super.setEnabled(value);
if (isEnabled()) {
setRolloverEnabled(true);
setBorder(BORDER_TOGGLE);
setForegroundColor(null);
} else {
setBorder(null);
setRolloverEnabled(false);
setForegroundColor(ColorConstants.gray);
}
}
}
customLabel = new DetailedLabelFigure();
Clickable button = new InactiveToggleButton(customLabel);
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent event) {
getPaletteViewer().setActiveTool(getToolEntry());
}
});
return button;
}
so you first need create a disabled figure for the toolentry, then
override the setActiveTool of PaletteViewer like below:
{
MyToolEntry tool = (MyToolEntry) getToolEntry();
if (!tool.isEnabled) return;
super.setActiveTool(tool)
}
Hope this help you!
