Handle Focus in Custom Controls [message #537892] Fri, 04 June 2010 06:32 Go to next message

Hello Experts

Our Control
I have a Custom SWT implementation of a Combobox/DropDownList.
This is implemented as a Composite containing a Text and a Button.
When the list is showed, we use a List control that is placed on top of everything and positioned at the Text and Button.

This works as expected.

The Problem
But we are having issues with focusLost and focusGained.
Ultimately i would like for any external component to throw a focusGained when any part of the custom control gains focus and only throw a focusLost when focus is lost from any part and no other part gains focus.

I would like to avoid handling focusLost and focusGained when focus is merely moved from the text to the button inside my custom control.

Do anyone know of an API to know, during focusLost, where focus will land?
Do anyone have an idea how to implement this in any way?

The implementation of CCombo handles these scenarios. So, have a look at
the code of CCombo esp the methods handleFocus(), isFocusControl() etc
for handling focus between Text/Button controls.
At any instance to deal with multiple controls, we generally use
display.addFilter() to get notified when focus is gained/lost on any
controls of the shell.
