QML Spinner doesn't work with MuseScore custom UI style
when loading the plugin in 2.0, it looks like this and doesn't change on click:
It breaks the page as expected though (by default 4 bars, hardcoded), and one can in/decrease the amount of bars with shift + up/down as well as typing blindly some number into the dialog. There is no visible indication.
There is another, possibly related issue though (in 2.0):
1.: Select a part of your score
2.: Open the "Break every X number of measures" plugin and press enter
3.: Select the same part again and reopen the plugin
4.: Now de/increase X and press enter
For the OP, this results in the generic key signatures(bflat, eflat, aflat in that case) being shown every 4 bars, where a linebreak used to be.
OP is using MuseScore guthub-MuseScore-musecore-3543170 on Ubuntu 14.04.
I can reproduce this on Windows 7
That input field is supposed to be a SpinBox, but doesn't look like one, it is lacking the up-/down arrows to in-/decrease the value.
