Dear experts,

is there a way I can realize that an SWT control is visible to the end-user, even not being the focus of the application?

*thanks*

Do you mean in another shell like in a pop-up message or something? You can do so with style bits [1]:

fShell = new Shell(display, SWT.NO_TRIM | SWT.ON_TOP | SWT.NO_FOCUS);

Thanks for the hint. !
No, I meant to find a way to verify that an SWT control is visible to the user.

Afaik isVisible() controls the "potential" of being visible, not is current status of actual visibility.
Otoh try isFocusControl() is too strict for my needs since I want to operate on parts which are not on focus too. !

isVisible() is what you want. The SWT book states that isVisible() returns true if it and all of its ancestors are visible. However, it could be drawn outside of the visible area (e.g. you move your window to the edge of the screen, or another control overlaps it) (or the user has switched off his monitor or closed his eyes Wink
