Applications stealing focus - making it behave like TweakUI?

[Andrew Robinson]

The setting focus to new applications by default on XFCE/X is not
quite ideal. Under the "Window Manager" settings, there are several
focus settings, but they really don't add up the way I'd prefer.

The problems I have experiened:
With "New window focus" and "Raise on focus" turned off sometimes
windows (dialogs) opened by the current application don't even get
focus (they sometimes go under the parent application which really is
not acceptible for most applications). Also, new windows (like GAIM
chat windows) never come to the front or have any kind of visual hint
that they want focus - so I miss the fact someone wants to chat.

With focus on, chats and other applications can steal the keyboard
focus which is really bad. I'm programming in Eclipse, and all of the
sudden my key strokes are going to a chat window instead.

For Windows there is a tool called TweakUI that does the ideal:
Popup windows, dialogs etc from the parent window get focus.
Applications that are not the current ones that try to get the focus
simply "blink" in the task bar. This way the user's attention is
received without interupting the focus of the keyboard.

Is there any way to get X and/or XFCE to behave this way?

Thanks,
Andrew
