Hello,
I have CheckboxTreeViewer control. There is a search into a treeitems and
I need to mark the result. I have the following label provider:
public class TreeLabelProvider extends LabelProvider implements
IColorProvider {
public Image getImage(Object element) {
return null;
}
public String getText(Object element) {
return ((CTTreeItem)element).getText();
}
public Color getBackground( Object element ) {
if ( foundObjectsIds != null
&& foundObjectsIds.containsKey( ( ( CTTreeItem )element ).getID() ) ) {
return Display.getDefault().getSystemColor( SWT.COLOR_DARK_BLUE );
} else {
return null;
}
}
public Color getForeground( Object element ) {
return null;
}
}
When I debug, I see that the method is called and a color is returned.
But the found items are not marked.
Any help
Regards

Hi,
I am aware that there are issues with the foreground color,
described in more detail here:
218420: [TreeItem] setForeground(Color), setForeground(int,
Color), setBackground(int, Color) does not work
https://bugs.eclipse.org/bugs/show_bug.cgi?id=218420
and here:
193933: [TreeItem] Text is not grayed out when disabled if
custom foreground color is set
https://bugs.eclipse.org/bugs/show_bug.cgi?id=193933
Basically they are related to the way the client-side library
represents TreeItems.
I could imagine the for similar reasons, the background color does
not work either.
Feel free to file a bugzilla.
Cheers,
Rüdiger
