Accessing measure in plugin framework

Reply Threaded

Hi,
I wanted to write a plugin to put a line break every X measure. So
far, there is no way to access measure objects in the plugin
framework.
So I took a look. I wrote scmeasure.h and scmeasure.cpp relying on
schord with a property "lineBreak". It should be ok.

Then I tried to figure out a way to go through the measures.
My first guess was using score->measures() and try to mimic
topNotes/note(idx)/notes.
The function note(idx) is not very effective but hell, on a chord (max
5 notes) it's ok. Doing the same on measures, it's not good I guess.

Morever score->measures() sends back MeasureBaseList so Vbox and HBox
as well. Should I filter to have only Measure or not ? If not how do I
do the cast ?

Second thought was making a scCursorMeasure, similar to SCursor for
chords. I created this and I commited it. It seems to work but it
looks heavy.
Please review. Maybe there is a simpler way to have the same feature?
A demo plugin named break4.js is also commited in r1816

My suggestion would be to extend the Cursor class:

- new function measure() which returns the current measure
- new function nextMeasure() which moves the cursor to the first
chord/rest of the next measure

Thanks a lot for the guidance! Why didn't I think about it myself...
It's in r1821.

Apparently you implemented it yourself as well in r1822... we have a
problem ... nextMeasure() and measure() are double in sccursor.h and
sccursor.cpp. Can you take a look and resolve the conflict ?
