Hi.

I display objects in the outline tree and the 'Properties' view displays =
properties for each object selected in the outline.
In one case I want to update the tree when a combo is changed. I change =
a value from 'true' to 'false' in the combo, and
that property change should update the tree (I want to change an icon). =
This works perfectly well in Eclipse 2.1.2 but
in Eclipse 3.0.1, the behaviour has changed. Now, the value is changed =
in the combo, but no event is fired, at least not
an event that can be caught so I can perform the update of the tree. =
Instead, the descriptor is marked dirty and rests
there. When I leave the combo and marks another property or clicks =
somewhere else in the entire GUI, a focus lost
event is fired and then I can do my tree update.

I'd really appreciate some help.

/Stefan

I see no other option than to override the ComboBoxCellEditor class. In =
the createControl() method I add the applyEditorValueAndDeactivate() =
call in the widgetSelected() method, and that will bring back the =
earlier behaviour in Eclipse 2.1.2.

protected Control createControl(Composite parent) {
=20
comboBox =3D new CCombo(parent, getStyle());
comboBox.setFont(parent.getFont());

comboBox.addKeyListener(new KeyAdapter() {
// hook key pressed - see PR 14201 =20
public void keyPressed(KeyEvent e) {
keyReleaseOccured(e);
}
});

comboBox.addSelectionListener(new SelectionAdapter() {
public void widgetDefaultSelected(SelectionEvent event) {
applyEditorValueAndDeactivate();
}
=20
public void widgetSelected(SelectionEvent event) {
selection =3D comboBox.getSelectionIndex();
applyEditorValueAndDeactivate();
}
});

comboBox.addTraverseListener(new TraverseListener() {
public void keyTraversed(TraverseEvent e) {
if (e.detail =3D=3D SWT.TRAVERSE_ESCAPE || e.detail =3D=3D =
SWT.TRAVERSE_RETURN) {
e.doit =3D false;
}
}
});

comboBox.addFocusListener(new FocusAdapter() {
public void focusLost(FocusEvent e) {
applyEditorValueAndDeactivate();
}
});
return comboBox;
}

My suggestion is that it should be configurable how the =
ComboBoxCellEditor should work. Let the present behaviour be the =
default, and make it possible to set some kind of "forceUpdate" flag to =
enable listeners to make an immediate update when the combo value =
changes.
