Transient Windows with GtkPlug / GtkSocket

["Lampersperger Andreas" <lampersperger andreas heidenhain de>]

Hello,

I've encountered a problem with the GtkPlug/GtkSocket mechanism and
transient windows: Various windowmanagers does not treat transient
windows as transient because gtk uses for the transient_for window the
xwindow-id of the GtkPlug-xwindow, which is no toplevel window.

test case: Use firefox and install adobe reader as a firefox plugin, so
that pdf's are directly shown in the firefox window. If you click on
"save a copy..." a "copy as"-dialog is shown. This dialog has the
wm_hints transient and modal. If you now click on the pdf-window the
"save-as" dialog is hidden by the firefox window and the adobe reader
(within the firefox window) is not responding, which is imho a failure.

Is this problem already known, or is there maybe already a solution?

Thank your for your answers,
Greetings
Andreas
