Re: [MACTCL] What is the purpose of tkDisplayIfNeeded?

[Michiel de H. <mjl...@ya...>]

Hi all,

I have summarized this discussion and provided a patch at
https://core.tcl.tk/tcl/tktview?name=883155fb98

This patch removes the [window setAutodisplay:NO] line and the tkDisplayIfNeeded code.
I tried this patch with the Tk test suite and found that it reduces the number of test failures by 1.

Best,
-Michiel.

 Just bringing some off-list discussion back to onto the
 list, it appears that the [window setAutodisplay:NO] line is
 needed to address some issues with drawing Tk windows under
 Cocoa, though the details are no longer readily available.
