[Plplot-general] Problem with colormap in Tk driver

[Roberto H. <ro...@ad...>]

Hello everyone,

I'm having a small problem when using the Tk driver. When I select Plot --> 
Options --> Palette 0 (or 1) from the plot menu I get the following error 
message: Error: bad window path name "". The a new toplevel window pops up, 
but it's blank.

I checked through the Tcl libraries and figured out that the procedures 
called when selectecting those items are:

------------------------
proc plcmap1_edit {plot} {
 
    global ncol1 plcmap1_col plcmap1_pos palette
 
    catch {destroy .edit}
    toplevel .edit
    dpos .edit
    wm title .edit "Color Map 1 Editor"
    wm iconname .edit "Cmap1 Editor"
    wm minsize .edit 100 100
 
    pack append .edit \
        [Buttons1:create [Buttons1] .edit.buttons $plot] "top fillx"
 
    pack append .edit \
        [ColorPalette1:create \
             [set palette [ColorPalette1]] .edit.palette $plot] "left filly"
}

(same for plcmap0_edit)
------------------------

The error message comes from trying to execute the last two "pack append" 
commands because of the "Buttons1:create" part. I looked for that and it 
appears to be a subclass.

I get the feeling that the problem lies in the fact that I built PLplot 
without the ITCL bindings. Am I right? Is ITCL necessary for choosing 
different palettes?

Thanks,

Roberto
