Testing on an AMD64 running Kubuntu 16.04, using wish: % tk scaling 1.3333333333333333 Testing on the same PC using undroidwish: % tk scaling 1.0006771314250538 As a result, content on undroidwish looks smaller when using density dependent units. chw added on 2019-05-15 20:15:48: Works as designed and was documentent about 3 years ago, see [427535dec3571d4d8afb52c0d0ae6c20e7835afa] anonymous added on 2019-05-16 13:50:49: It seems I forgot to RTFM.

More on this issue:
While tk seems to be correctly set to display the content, the sdltk window borders are scaled by the -sdlxdpi value given at the command line, which seems to be approx. 240.0/72 = 3.333.., in the above example. See this screenshot. The size of the font in the console is not a problem; it will resize properly once the console is redrawn by Tk. But... I have not found a way to set sdltk's window borders. Tk commands for toplevel windows do not seem to influence sdltk's window decoration in undroidwish. I can make them disappear, e.g. by running `wm overrideredirect`, but then the ability to move the windows around is lost. How can one change window decoration sizes in sdltk? It seems they should be tied to the `tk scaling` that undroidwish comes up with initially. chw added on 2019-05-17 17:43:53: There are some hard coded steps in which the window manager decorations are adapted to the dpi ratio of the screen. This was needed especially on Android devices which have a great bandwidth of dpis (140 ... 550). There's certainly room for improvement but I have no time for it. If you'd like to contribute a patch, I'll gladly integrate it. anonymous added on 2019-05-17 21:48:44: What would be a location to start looking? chw added on 2019-05-18 04:15:23: [b65fa01ff47e67b9ff62e3e404ee97fbdf3397f9] [6586a4973f3eebf82fb9487f2221554a5f0a48c3] search for "dpi" and "dec_frame_height" |
