> <\body> The most annoying problem with the version under is that the colors of various widget elements are incorrect. This problem is most important when using the \PDark mode\Q. It is fairly difficult to understand for me how these things work precisely in and in the implementation by Max and Miguel, so help here would be welcome. It would probably be best to abstract things a bit and to introduce a routine <\cpp-code> QPalette tm_palette (); for obtaining the color palette and consistently use this for all widgets. In order to make things customizable, we might also introduce an enumeration <\cpp-code> enum gui_color { GUI_DARK, GUI_LIGHT, ...}; with the counterparts for , , etc. We also need the corresponding converters <\cpp-code> color as_color (gui_color col); QColor as_qcolor (gui_color col); and maybe an initialization routine <\cpp-code> init_gui_colors (); that could read some of the values from defaults (which could be different in light and dark mode) or from the user preferences. Here follow some specific problems for the current implementation ( 10.14.6): <\itemize> (dark mode) background too dark for wait widget. (dark mode) font browser: selected backgrounds are too dark (by the way, they are grey instead of blue, but become blue when one clicks on them, before returning to grey) and so are the borders of the -output widget. (dark mode) > very dark background for widget. (dark mode) color menus on toolbars > very dark background for widget. (dark mode) > very dark background for widget. When selecting \Pnon native menubar\Q in (SVN version of ), the color of the menu bar is ugly (too light). (dark mode) When pressing an icon on the toolbars, the pressed color is too dark. <\itemize> : the colored entries do not work; they do work in the pulldown menus for colors the toolbars. In the top-level menu for an empty document, click on and note that and are greyed out. Now don't release the mouse button, click on , and then go back to ; at this point, and are no longer greyed out. Open a pulldown menu on one of the toolbars. Then click elsewhere on the toolbars; the pulldown menu icon remains highlighted until you hover the mouse over it. The extension is not added to the list of supported formats when browsing image files. But images do work (when changing the filter to ). I could not manage to make the resize the toolbars in an appropriate way. By default, the icons and the fonts are a bit too small, but the retina versions are way too large. Note that the SVG versions of the icons seem to work in , but I still did not manage to get them at arbitrary sizes. Denis (Raux) and Jean-Marc (Notin) managed to compile for ARM (an M1 based ), using 5.12. The native menu again seems to trigger a lot of segfaults, especially when opening documentation using the menu. This problem disappears when using the non-native menubars (, SVN version of). <\initial> <\collection>
