Several problems in KDE/KWin

Several problems in KDE/KWin

[Werner Fink]

Two problems have beem seen:

  Emacs does not keep the "iconic" information in KDE/KWin
  Emacs does not un-maximize in KDE/KWin

When starting emacs in kde in the background iconified like:
 emacs --iconic &
it shows only in the menu-bar of kde but not in the screen (by intent). Now, if
I save the desktop configuration, quit kde and start it again, emacs is startet
- what is expected - but not iconified - what is not expected.

After maximizing an emacs window, it is not possible to un-maximise it.
It may depend on font size and desktop geometry.  I have these in
Xresources:
 Emacs.font:     10x20
 Emacs.geometry: 80x38
 Size of desktop is 1400x1050.
The symptom is that after maximizing, the "maximize/un-maximize" button stays
in the "maximize" state (one square), intead of going to the "un-maximize"
state (two squares).

Just found out that the second problem depends on the max resize
request send from KWin. Im my test case this is 1680x975 but
emacs with gtk response with 1672x962 which seems to leave the
KWin in the state `not maximized' which leads on the next press
on the min/max button to a further maximize.

How this problem can be solved?  This problem does not happen
without gtk but X standard toolkit.  The later seems to add
the remaining pixel to the internal border width/height.

What does the step "save your desktop configuration" mean exactly?
Are you running a KDE or GNOME desktop environment?
AFAIK saves KDE the states of opened/iconic windows and tells via kwm
the application to be opened/iconic when it is started the next time.

In your case emacs would start iconic, but than the KDE window manager
would tell emacs to show up.

Could that happen in your setting?

Did you try this in your current environment or within an older SuSE?

As no one is interested to fix this bug I've added a
workaround to switch to the Athena/Xaw3d toolkit
instead of using GTK which is done by this scriplet:

  #!/bin/bash
  # Avoid trouble with maximize/minimize within KDE (bug #345669)
  #  -> under KWin emacs does not maximize in the correct way if
  #     GTK/GDK is used as toolkit.  After click on the maximize
  #     button emacs shrinks to fit to the current font which
  #     destroys the maximize state in KWin.
  # Avoid trouble with "iconic" state information (bug #342385)
  #  ->  under KWin emacs with GTK/GDK toolkit does not hold its
  #      "iconic" state if a desktop state is saved before logout
  #      and restored after login.
  toolkit=gtk
  KDE_FULL_SESSION=$(xprop -root KDE_FULL_SESSION 2>/dev/null)
  case "$KDE_FULL_SESSION" in
  *true*) toolkit=x11
  esac
  exec -a ${0} ${0}-${toolkit}
