Tk Source Code

When a combobox is in the disabled state, its arrow is not grayed on Unix. This can be fixed by inserting the following in the styles altTheme, clamTheme and defaults.tcl in library/ttk:

ttk::style map TCombobox -arrowcolor [list disabled $colors(-disabledfg)]

Merged to core-8-6-branch and trunk.

Thanks again for the report and even more for the patch!

Thanks for your answer. I have grouped the multiple [style map TCombobox] statements into a single instructions.

Looks good. Maybe it's better to add the options to the already existing [style map TCombobox] statements (although this really doesn't matter).

I looked at the TSpinbox style, which already has the arrowcolor bindings. I suppose the Windows and Mac themes don't need them because they have native bindings. In Motif, the background of the arrow is grayed when disabled.

Thanks for the report and for the patch!

Test script:

package require Tk
pack [ttk::combobox .c]
.c configure -state disabled

I have committed the patch in a branch for easy testing: [e90562e585]

Following your report I have changed the alt, clam and default themes only. Why is there no need to modify the other themes accordingly, e.g. aqua or motif?
