Hi,

I have an application that I want to always remain on top. I do this using a Java Timer. However, a couple keyboard shortcuts such as Alt-F3 & Alt-F9 minimize this screen. How can I disable use of such keys on my system so that even if users hit Alt-F3 & Alt-F9, nothing happens ?

Thanks!

I always consider disregarding you user's wishes to the point of pissing them off
to be the epitome of UI design.  Why is that that only Window's programmers want
to do this type of thing???

If you are using KDE, execute 'kcontrol' (The KDE Control Centre). In the "Index" tab, take "Regional & Accessibility" -> "Keyboard Shortcuts". Here, you can disable shortcut keys for minimizing window.

If you are using Gnome, execute 'gnome-keybinding-properties' to change keyboard shortcuts.

The question perhaps is what the blazes "Always on top" has to do with minimization/iconification to do... The answer is "nothing", of course:-)

Can I somehow intercept these calls either in C or Java so that although Alt-F9 is enabled to "minimize" a screen, that actually doesn't happen because of the intercept code I put in ?

Thanks to all!

Hm, I don't really think you'll see the key events properly... Test it with xev and you'll see that the Alt_L keypress gets through to your app, but never the F9... All you'll see is the keyrelease;).
Perhaps you could register your own keyhandler, but really.... these things are configurable in most desktops, so programming for one set of keystrokes would land you nowhere anyway.

You could scrounge up the code for hotkey perhaps... Just to see what it'd entail:-).

Many windowmanagers would handle "transient windows" like they couldn't be iconified... Mayby try use that.
