I've figured out how to delete multiple selections. If anyone runs into
the same problem, here's what I have learned: pygtk does not allow
treemodel.remove(iter) in the selected_foreach(...) function, so I had
to store all the iterators for the selected rows and then go back to
delete them. The iterator parameter of the function called by
selected_foreach is not the actual treestore row iterator, so I had to
get it by using treemodel.get_iter(path). Only then was I abe to use
treemodel.remove(iter) to remove the row. Here's my code:
# list that stores all the iterators of the selected rows
selectList = []
# function to get iterator of selected row
def GetSelectedIter(model,path,iter,rowList):
selectIter = model.get_iter(path)
rowList.append(selectIter)
# get reference to each row
selection = watchvar_treeview.get_selection()
selection.selected_foreach(GetSelectedIter,selectList)
# actual removal of rows
for iter in selectList:
watchvar_treestore.remove(iter)
