I'm using Eclipse 3.0M8 on Windows XP (and occasionally on Mandrake 9.2). I would like the perspective window under the mouse pointer to react to scroll wheel events without having to first click in that window. I want my focus to remain in, say, the editor, but to be able to use the mouse wheel to scroll the 'Outline' or 'Package Explorer' trees without having to click away from the editor to do it. I'm *not* advocating hover-to-focus though; I still want to click-to-focus a window (maybe that could be an additional option?). And I am *not* talking about single-click to open files, or even mouse-hover to open files (both of which are already options in M8). I got used to this behaviour in other apps (Microsoft Outlook and Mozilla Thunderbird being a good examples). I find it really intuitive. Thanks -- Sean
This has come up before, and the problem is that this is not native behaviour on win32 (whereas it is on mac, for instance, and eclipse does work like that there). The other win32 applications that do this are changing the behaviour at the application level (ie.- receive the scroll event, see that the pointer is over another widget that will take the event, and redirect it there). I saw a comment somewhere that this is often configurable on win32 in the mouse setup if you have your proper mouse driver installed. Making this change essentially makes the scroll-the-hovered-widget behaviour native, and this will be reflected through swt accordingly.
Can you implement the Display.post(Event event) method to accept event.type == SWT.MouseWheel? Or is there any other way to easily redirect mouse wheel event? One little workaround is to find if the control at the cursor is inside any ScrolledComposite and then try to scroll it, but what if control is instance of Scrollable (which cannot be scrolled programatically if I am right)?
