an XWithdrawWindow unmaps a window and sends a synthetic UnmapEvent after
that. when the second UnmapEvent arrives we have to set either the WM_STATE to
WithdrawnState or delete it. i decided for deletion so its absolutly clear
its not any longer under our control
<Workspace> in apps-file. Reason is, that an unmanaged window is not yet
assigned to an workspace and thus the returned workspacenumber is -1 ... which
leads in combination with getWorkspace(nr) to an invalid workspace (0x0) ...
This also fixes the problem with several deiconify-modes of the iconbar, when
the iconbar is in icons-only mode (same reason)
The other changes in the files are just cosmetic, i throw out the comments
about the changes Simon did coz they make sense and are correct imho.
only when using "imlib_load_image_with_error_return" as the loading
function imlib2 seems to avoid trouble when an image with <filename>
doesnt exist. all other loadroutines lead to heavy problems when
fluxbox shuts down and tries to restart (memleak(?), distorted xressources
etc)
i ll analyze this further. another open issue with imlib2 is that it
doesnt work when xserver/fluxbox is running in dualscreen-mode (not
xinerama), no valid pixmaps are visible on the second head. dunno why
(yet).
besides xpm. to get imlib2 support in fluxbox one has to
./configure --enable-imblib2
default is disabled. a fluxbox-binary that supports imlib2 will have
IMLIB2 in "fluxbox -info"-output
explanation to the changed files:
* xft.m4 -> acinclude.m4 + added ac_path_generic.m4
(from http://ac-archive.sourceforge.net/Miscellaneous/ac_path_generic.html)
* configure.in, Makefile.am, src/FbTk/Makefile.am changed to handle
imlib2-support
* Font.cc/hh Image.cc/hh App.cc fluxbox.cc consistent way of init for global
stuff for fonts and imagehandlers.
* rest of changes just add the imlib2-code, pretty straightforward
* synchronize _NET_WM_STATE in Ewmh.cc
* added FluxboxWindow::setFullscreen(bool) to Window.cc
furthermore, if a window is in fullscreenmode any existing shape is
disabled (looks pretty annoying in mplayer for example)
