Summary0001125: Strange interaction between tk_getOpenFile and vtkTkRenderWidget
DescriptionDear,

I have a strange behavior in a TCL script (see below). If the line "reader SetFileName $file_in" is included at start the TkRenderWidget reports the following error when the program is terminated:

A TkRenderWidget is being destroyed before it associated vtkRenderWindow is destroyed. This is very bad and usually due to the order in which objects are being destroyed. Always destroy the vtkRenderWindow before destroying the user interface components.

But try to play with the two lines right below vtkPolyDataReader and you'll see different (but deterministic) behaviors depending on which lines are included (You get different different mouse interaction, wireframe on/off works/doesn’t work)

Hope you'll be able to track the bug down.

I'm running on a Dell inspiron 9100 with XP SP1, VTK 4.4 & TCL/Tk 8.3.2 (info patchlevel).

Best wishes,
Per R. Andresen

 I don't know about the strange interaction you are reporting here but this error message is ususally seen when not exiting the tcl app correctly. This should be done by calling:

     proc cb_exit {} {
        vtkCommand DeleteAllObjects
        exit
    }

which is found in VTK\Wrapping\Tcl\vtkinteraction\bindings.tcl .

You should bind this callback to the toplevel window using:

wm protocol . WM_DELETE_WINDOW cb_exit

This is also the callback that should be bound to any "Exit" command you have in a "File" menu.

 I'll try that file name with forward slashes:
VTK/Wrapping/Tcl/vtkinteraction/bindings.tcl
