While working on my custom panel, I thought I had everything correct to
allow a single QComboBox to populate a checkable QListWidget based on
what was selected. However, now I am running into an issue where items
added to the DataArraySelection do not get removed when I had thought
they would. I have an example reader plugin which shows the problem. It
is based off of the CSVImageReader, just so I can implement the panel.
Once you load a file, the QComboBox and QListWidget get populated like
they should. Then if you press accept, you can see that the RequestData
is run with the correct information. Then if you switch to the second
option in the QComboBox, you can see that the QListWidget gets
repopulated correctly. Then if you hit apply again, it seems to prepend
the new options to the DataArraySelection when it should delete the
current list and then add the new items. At this point if you check any
box, updateSelection segfaults since there are more items in the
DataArraySelection then on the GUI.
In my SetSource function, you can tell that there are only two items in
the DataArraySelection. SetSource is the only place that adds/removes
from the DataArraySelection, so I'm stumped as to why the previous items
are still there.
I included a tarball of the test. It contains a csvim file to load.
Quick Steps: Load Plugin, Load csvim file, Press Accept, Switch
QComboBox to 'Value 2', Press Accept, Click first checkbox = segfault.
Any help would be appreciated.
Thanks,
Brian Panneton
