Of course , you can try with THintWindow as Ondrej mentioned, but if 
form is bsNone than it should not take focus. Don't know what happens 
with framed forms on linux....if you click on frame then X11 rules are 
unpredictible.
Also, you can set QWidget attribute QtWA_ShowWithoutActivating, but that 
should be setted up before form is shown (eg in FormCreate call 
HandleNeeded and set focusPolicy and attributes). See 
QtWSControls/qtint, there's dnd imagelist operation and we are using 
ShowWithoutActivating etc ...
