BadWindow (invalid Window parameter)

[Tzvika Faibish]

Hi Guys,
Once a day I get stuck with my CDE windows on my HP-UX 11. on my ".dt" directory I get error file which display this:

ly2005:tzvika {~/.dt} > more errorlog
*** STDERR(1): (/usr/dt/bin/dtexec) /usr/dt/bin/dtstyle: PID 7661: Tue Dec 30 15
:18:34 2003
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 20 (X_GetProperty)
Resource id in failed request: 0x1400010
Serial number of failed request: 81
Current serial number in output stream: 81

Do you know what to do in order to fix this stuck/crach windows?

The interpretation of this is that dtexec (used to launch apps from the front panel in CDE) reported the error from the program dtstyle.
The error dtstyle reports is that the window ID (a unique id for each X window on the screen) is invalid. This is generally a programming problem but can be caused by some misconfiguration.

What kind of X display device are you using? I could conceive that this might happen with some X configurations, especially PC Xservers that CDE does not know how to handle.

dtstyle is known to work with 8 and 24 bit visuals since that is what HP workstations have delivered. PC Xservers (and Linux) can support depth 16 visuals and I'm not sure that CDE knows how to work well in this environment.

A couple of questions:

- can you duplicate the problem or is this a one time occurrence? how do you duplicate the problem?

- can you supply the output of /usr/contrib/bin/X11/xdpyinfo?

Thanks and Happy New Year...

Rick,
Thanks for your help. Iwant to mention that I'm working with "reflection" (emulator to Unix) and also several users work with the same configuration but don't have this problem.

Reflections/X has an interesting feature that might make things difficult for CDE. It has a feature that you can enable that can let you
run in 'rootless' mode, where the X windows are intermixed with the MicroSoft windows. While this is quite useful from a user standpoint, it is quite different from a 'normal' Xserver/workstation environment. X programs expect to be able to write to the 'root' window of the screen. In rootless mode, they can't.
dtstyle expects to read and write attributes to the root window to change the background and so on and in rootless mode you can't do this.

Suggestions:

- enable 'windowed' mode in the Reflections/X options menu

- check the security settings - I have a feeling that security settings in Reflections/X may cause some problems.
