Scrollbars slider becomes to small/invisible if text widget size is reduced or if the text is quite long. my $scrollbar= $ParentFrame->Scrollbar(); $WidgetTextView = $ParentFrame->Text( -yscrollcommand => ['set' => $scrollbar], ); $scrollbar->pack(-side => 'right', -fill => 'y'); $WidgetTextView->pack(-side=>'right', -expand => 1,-fill => 'both'); $scrollbar>configure(-command => ['yview' => $WidgetTextView]); Or even the simple: $WidgetTextView= $ParentFrame->Scrolled('Text')->pack; Note that both (above) work fine with 8.5! However, the pure Tcl/Tk version seems to work fine also on 8.6.9: $int->Eval(<<'EOS'); text .t -yscrollcommand {.s set} scrollbar .s -command {.t yview} grid .t .s -sticky nsew EOS

Please note that in my first example, the slider is visible BUT is not usable (it is as if the mouse pointer would not control it, i.e. it can control it only in a very specific and small area of the slider. In the second example, the slider decreases in size. The third, pure Tcl/Tk, it works just fine. Am So., 16.

I could reproduce the issue even with pure Tcl/Tk so I posted also a ticket on the Tcl/Tk page. Am So., 16. Juni 2019 um 01:01 Uhr schrieb ray sakamoto < raysakamoto2019@gmail.com>: Show quoted text

I can confirm it is an upstream bug and not a Tcl::pTk issue. Using ttkScrollbar instead of Scrollbar makes the slider smaller (in the situation described in my post), but at least does not deceive the user with a bigger slider that does not work. Am So., 16.

I want to note here that on the upstream ticket, one of the Tk Aqua developers not only suggests using new Ttk scrollbar (to appeaer in 8.6.10) as a workaround, but also avoiding the non-Ttk scrollbar entirely on Aqua. Another developer thinks there is still use cases where the non-Ttk scrollbar is acceptable. Both are currently considering leaving the non-Ttk scrollbar as "broken" though, due to the difficulty in properly fixing it as well as keeping a consistent appearance on older macOS versions. I would hope that the issues/limitations and suggested workarounds can be better documented in 8.6.10.
