[news.eclipse.platform.swt] Change background image

[Lan <lanlan99999@xxxxxxxxxxx>]

Hi guys,

I have a RCP application that I want to change some control's background 
image on the fly. I tried control.setBackgroundImage(image); The new 
image appeared on the control. However, when I resize the rcp 
application, the view that contains the control(a table) loss focus and 
the previous image appears again... I then tried:

	control.getBackgroundImage().dispose();
        control.setBackgroundImage(image);

However non of the two images are showing up any more... Can somebody 
show me the correct way to switch background colour and background image 
on the fly(It is already showing)?

Thank you in advance,
Lan
