wxPython | wxDataViewListCtrl get all selected rows/items

I`m using wxPython in conjunctions with wxFormBuilder. I have a wxDataViewListCtrl with 5 columns to list my values. The user can select one or more rows (style = wxDV_MULTIPLE). If the user only select one row i can catch it with this method:

def showContextTZM( self, event ):
    if self.m_dvlc.HasSelection():
        item_id = event.GetItem().GetID()

If the user selects more than one row I only get the item where the cursor is placed. I did not find any method to get all selected items.

Thanks for answers.

For some reason the functionality you need is not documented (at least in the only really usable wxPython/Phoenix docs). It is indeed present in the current wxWidgets documentation. But you can find it in the wxPython package:

wxPython classic, in wx.dataview:

def GetSelections(*args, **kwargs):
    """GetSelections(self) -> DataViewItemArray"""
    return _dataview.DataViewCtrl_GetSelections(*args, **kwargs)

wxPython Phoenix, in .../site-packages/wx/dataview.pi

def GetSelections(self):
    """
    GetSelections() -> DataViewItemArray

    Returns a list of the currently selected items.
    """

It works at least in classic 2.9/3.0 (not tested by me for Phoenix).
