Tk Source Code

When the cursor is on 0th column of Tk text row, we see the cursor width = 1, instead of 2 as set with -insertwidth option.

Seemingly 1 pixel of the cursor width is lost at 0th position. Though, it's for 0th column the cursor is especially wanted to be wider than 1.

Checked on Linux and Windows.

However minor, this issue looks strange. It's specific for Tk text. No problems with other Tk widgets and with text widget of other libraries.

I solved this problem in alited editor (binding to cursor position change) - alas, it's my "workaround" only. Hopefully, there is a better way.

puts "Tk v[package require Tk]"

pack [text .txt -height 4 -width 50 -undo 1 -insertwidth 2] -pady 4 -padx 4
pack [entry .ent -width 50 -insertwidth 2 -textvar ::ent] -pady 4 -padx 4
set ::ent {  1. 123 5 789012  LINE-1}
.txt insert 1.0 $::ent\n\n
focus .txt

Hi François,

No, not at all a big issue. Just interesting.

Would you share a link to the revised text widget, or an info how it's available/used in the current Tk versions?

Please share it and then close the ticket.

Thanks in advance.
