Tablature shown as treble staff in "Instruments" when Clef is hidden
Nightly d08e14c (4 Jan 2016) on Win 7 HP / MS 2.0.2 on Win 10.
1. Create a new linked Guitar staff/TAB score.
2. Right click on tab staff, select "staff properties," then untick "show clef," and click "OK."
3. Open the Instruments window ("I").
Expected result: The words "Tablature" and "Tab 6 str. simple" should be visible.
Actual result: The line wrongly shows "Treble clef 8vb" and "Standard."
Comments
My findings are as follows :
The bug lies here https://github.com/musescore/MuseScore/blob/d8e437343562c47561d4a14cafd….
The comparison done in the two loops in the following function https://github.com/musescore/MuseScore/blob/master/mscore/instrwidget.c…
fails because of inclusion of genClef comparison in the isSameStructure function.
If we remove that comparision from the isSameStructure itself, it will lead to some other breakdowns possibly ( wherever the staffTypes are compared using '==' , as this operator itself calls isSameStructure ).
So, a hack would be to modify the genClef values of both staves to be true in the instrwidget.cpp#171 StaffListItem::setStaffType before doing the comparison and restoring them on exit.
But this is clearly not an elegant approach to follow.
I would like to have the opinion of other developers on how to fix this.
