[Xcircuit-dev] Annoying focus bug (Tcl/Tk version of XCircuit)

[Wim Vereecken]

Hi Tim,

In the Tcl/Tk version of xcircuit 3.6.xx (up to 3.6.145), there is an 
fairly annoying bug which causes popup windows (such as the output 
dialog box, shift-W) to 'popup' _under_ the main XCircuit window. The 
reason for this seems to be the focus-stealing prevention feature of 
some windows managers (KDE3.x on fedora enterprise/kubuntu/...).

FWIU, the KDE windows manager does not allow a toplevel window to grab 
focus if the 'active window' (i.e. the main XCircuit window) is not 
in focus. However, the popup windows (see wrapper.tcl) are created 
without defining a group of related windows. Hence, the KDE window 
manager is not informed that the main XCircuit window and its dialogs 
belong together, so that popups will not raise after a "wm 
deiconify/raise" call.

Possible solution for the .output dialog in wrapper.tcl (xc-3.6.145):

line 18:
--------
  toplevel $name
  wm title $name XCircuit

Add $name to group '.'
----------------------
  toplevel $name
  wm title $name XCircuit
  wm group $name .



line 798:
---------
  toplevel .output -bg beige

Add .output dialog to group '.'
-------------------------------
  toplevel .output -bg beige
  wm group .output .


As this 'bug' didn't annoy me that much for the other dialog boxes, I 
haven't tested it for .filelist, .dialog, etc... However, I suppose 
the solution is the same as described above.

Kind Regards,
Wim
