For anyone having experienced the 'frozen' Arranger bug (non-responsive to mouse):
We talked about this before, I said it was an MDI thing, observable in Qt5Creator, and I mentioned some ways around it, like fooling with the Appearance styles. This thing has plagued Qt5 MusE for a while. I have tried hard but it has stumped me. Hey! Last night I made some progress. Hope to have something soon. As in... all Appearance styles working with all stylesheets, and NO frozen Arranger. (Working on a couple of remaining areas.) Wish me luck. Tim. Tech stuff: Wow! Oxygen and Breeze are reeeally picky about how and when, and how many times you set the application style and stylesheet. The freezing seems to toggle on/off each time the style is set. And I found a dumb pseudo-buggy Qt thing: Believing it wasn't possible, I discovered that you CAN in fact ask what the current style's name is by calling the style object's objectName(). We use it already, but duh, somehow I didn't see that. But, for some reason we ALSO had code which calls setObjectName(). Seeing that, I reasoned that since Qt already takes care of object naming for us, I removed all such calls. Good. Armed with the ability to get the current style's name, I added some missing optimizations to the routines that set MusE's style, to ask if the current style is ALREADY the desired style. Good. Then, lo and behold I found that the string returned by the style object's objectName() is lowercase, but the strings returned by QStyleFactory::keys() are not ! As in: "oxygen" and "Oxygen". Phht. That means we MUST do case-insensitive comparisons when asking such questions like comparing the current style name with the names in the QStyleFactory keys. Done. Good. Then I found it worked better if setStyleSheet is called before setStyle, not the other way around like it is now. I can now select any Appearance style and the Arranger doesn't freeze, even after restarting! I can now set any Appearance stylesheet (say, Ardour.qss) AND any style (say Breeze), click OK and the Arranger doesn't freeze. Yay ! (It does upon restarting. I'm working on it... I see more potential toggling calls to setStyle and setStyleSheet. I mentioned earlier that Oxygen and Breeze don't seem to like multiple calls - it seems to 'toggle' the freezing effect on/off. Arranger also freezes when you go back to normal light stylesheet. I'm working on it...) ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Lmuse-developer mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/lmuse-developer
