Well, I can seemingly easily switch between qx.theme.Classic and
qx.theme.Modern (for example), but not my app's own theme. I created a
timer that fires every second and changes some stuff while I'm testing,
and during this, every 3 seconds it switches between themes:
if ((counter / 3) % 2) {
qx.theme.manager.Meta.getInstance().setTheme(qx.theme.Classic);
} else {
qx.theme.manager.Meta.getInstance().setTheme(qx.theme.Modern);
}
(It's probably worth mentioning that TabView tabs don't get redrawn
until I hover them, and once returning to Modern, the tab background is
taken from a system colour, unlike previously where it was white)
If I replace those qx.theme.* with myapp.theme.Theme and
myapp.theme.Theme2, where Theme and Theme2.js only differ in that they
refer to Font.js and Font2.js respectively, and all theme files extend
qx.theme.modern.Whatever, there will be no theme switching. There might
be a too strict check somewhere in the code whether to switch or not...
I'm not sure, I haven't looked yet.
If I edit for example qx.theme.classic.Font.fonts["default"].size and
switch away and back to the Classic theme, the font size will be updated
as appropriate. This confirms that my "double buffering" idea as
mentioned in the previous email, could be used, and so, there's no need
to create more than two themes just to have dynamic sizes. As long as
the theme switching actually does work – I guess if the app-local themes
extend different themes, they might be considered different enough to
force a redraw.
Also found that only Meta setTheme does actually do anything. If I had
just done
qx.theme.manager.Font.getInstance().setTheme(qx.theme.classic.Font) it
would not have changed a thing.
