Hi there, I'm the developer of Shutter (a screenshot taking application written with gtk2-perl). After upgrading to the latest versions of Gnome (2.28) and Gtk+ during the last days I've discovered that the client-side window mechanism is "breaking" some of the functionalities of Shutter.
There is a function called "Section" that allows you to capture one of the subwindows of a foreign window by moving the mouse over it. The "Section" function queries the window tree information by calling an xlib function, XQueryTree. I know that before Gtk+ 2.18 most of the widgets had a corresponding xwindow. The information about the subwindows were used to detect them and draw a rectangle around them that illustrated their geometry. If I understand the changes correctly this means that the XServer no longer knows about the subwindow hierarchy of a Gtk+ window and I can't use the XQueryTree function any longer, right? I know that is possible to query the children of a GDK-window, but this works only if your own application created that window. Shutter needs to get the children of foreign toplevel windows. Does anyone have an idea on how this problem could be solved? Maybe with the help of AT-SPI? Accerciser is using it (the python bindings) to query the structure of toplevel windows: http://live.gnome.org/GAP/PythonATSPI But I would love to see a solution that I can implement with perl ;-) Thank you very much for your help. I hope I've explained everything clearly enough.
