Description: |
This is my test script: package require Tk pack [frame .root -padx 10mm -pady 10mm] -fill both -expand 1 pack [checkbutton .root.cb -text "Check me"] pack [frame .root.rb] for {set i 0} {$i < 3} {incr i} { pack [radiobutton .root.rb.rb$i -variable rb -value $i -text "Select $i"] } .root.rb.rb0 select pack [label .root.lb -image [image create photo -file available.gif] -text "Image label" -compound left] set input "Input text..." pack [entry .root.e -textvariable input] I'm running it on Hi-DPI display in Windows and OSX, and see different results: https://www.dropbox.com/s/wq2kyf0wfwfdo7b/hidpi-tk-osx.png?dl=0 and https://www.dropbox.com/s/k5a3bn2cieknmne/hidpi-tk-windows.png?dl=0 So Tk under OSX uses correctly sized radiobuttons and checkbuttons, and scale image automatically. When Windows version scale fonts, but not all widgets (entry is scaled well) and not images. I think Windows Tk behavior should match OSX one. For example, PuTTY screenshot with correctly sized widgets: https://www.dropbox.com/s/2l89qw4azcpcfrd/putty.png?dl=0 | |||

See: https://core.tcl-lang.org/tk/info/3c6660b6f0bed337 sergiol added on 2017-12-13 00:29:23: It seems to me `SetProcessDpiAwareness` is a thing we should invest some time, to see if it works: https://msdn.microsoft.com/en-us/library/windows/desktop/dn302122(v=vs.120).aspx anonymous added on 2015-05-25 03:38:43: Duplicate of [0917069c05]? anonymous added on 2015-05-18 14:33:54: the problem is the same with ttk widgets (they also a bit blurry) apnadkarni added on 2015-05-18 11:41:30: Generally ignorant of such matters, but you might possibly have better luck with the ttk widgets (ttk::checkbutton etc.) as I think they use more of the native controls. Might be worth a shot. |
