Yesterday I made the mistake of using conda install in my main python3/qt5 environment. This ruined the look of tabs and buttons in Leo's window.
Alas, *it's not easy to downgrade to an earlier version of qt5 using either conda or pip*. Make sure you can continue to use earlier versions of Qt4. Make backups of theme files before messing with them. Happily, it appears that all problems arise from Qt #59533 <https://bugreports.qt.io/browse/QTBUG-59533>: "Qt >= 5.8 and 5.10+ stops parsing stylesheet when it sees ~=". See also Leo #804 <https://github.com/leo-editor/leo-editor/issues/804>. Eliminating "~=" from theme .leo files fixes all problems, except that Leo can no longer change colors in the status area. For example, the status area should be colored red when a search fails. Older versions of Leo switched colors using code. It will be necessary to do so again. We can't wait for Qt to fix this problem. Edward -- You received this message because you are subscribed to the Google Groups "leo-editor" group.
