Thank you for your report and PR Patrick.
I agree, it would be better to to set the "type" attribute to "dialog" for the
FileDialog window. Tk does it for its dialog windows. But it is more complex.
* It should be set not only for FileDialog, but for other dialog windows
implemented in Python too (including dialog windows specific for IDLE). I am in
process of working on making dialog windows implemented in Python looking and
behaving closer to dialog windows implemented in Tk. The hardest part is
writing tests for this.
* This code should be executed only on X Window. On macOS and Windows different
code is needed. From Tk sources of ::tk::dialog::file::Create and
::tk::dialog::color:: :
if {[tk windowingsystem] eq "x11"} {wm attributes $w -type dialog}
And in ::tk_dialog and ::tk::MessageBox :
if {$windowingsystem eq "aqua"} {
::tk::unsupported::MacWindowStyle style $w moveableModal {}
} elseif {$windowingsystem eq "x11"} {
wm attributes $w -type dialog
}
And ::tk::dialog::error::bgerror uses moveableAlert instead of moveableModal.
