copied!<p>The class <code>ObjectListView</code> does not seem to contain that functionality. After digging in the code for a while I have decided to extend it.</p> <p>You can derive your own class from <code>ObjectListView</code> and force the event in. You have to override <code>_HandleLeftDownOnImage</code> and <code>SetCheckState</code> methods. Or you can just change the ObjectListView code if you like. I have derived a new class:</p> <pre><code>import wx.lib.newevent OvlCheckEvent, EVT_OVL_CHECK_EVENT = wx.lib.newevent.NewEvent() class MyOvl(ObjectListView): def SetCheckState(self, modelObject, state): """ This is the same code, just added the event inside """ if self.checkStateColumn is None: return None else: r = self.checkStateColumn.SetCheckState(modelObject, state) # Just added the event here =================================== e = OvlCheckEvent(object=modelObject, value=state) wx.PostEvent(self, e) # ============================================================= return r def _HandleLeftDownOnImage(self, rowIndex, subItemIndex): """ This is the same code, just added the event inside """ column = self.columns[subItemIndex] if not column.HasCheckState(): return self._PossibleFinishCellEdit() modelObject = self.GetObjectAt(rowIndex) if modelObject is not None: column.SetCheckState(modelObject, not column.GetCheckState(modelObject)) # Just added the event here =================================== e = OvlCheckEvent(object=modelObject, value=column.GetCheckState(modelObject)) wx.PostEvent(self, e) # ============================================================= self.RefreshIndex(rowIndex, modelObject) </code></pre> <p>Then I used that class instead of <code>ObjectListView</code>:</p> <pre><code>self.dataOlv = MyOvl(self, wx.ID_ANY, style=wx.LC_REPORT|wx.SUNKEN_BORDER) </code></pre> <p>Bound the event:</p> <pre><code>self.dataOlv.Bind(EVT_OVL_CHECK_EVENT, self.HandleCheckbox) </code></pre> <p>And wrote the handler:</p> <pre><code>def HandleCheckbox(self, e): print(e.object.title, e.value) </code></pre> <p>I am certain that this is not the best way how to do it, but it is simple and effective hack :-D.</p> <hr> <p><strong>Edit:</strong> Complete example</p> <pre><code>import wx import wx.lib.newevent from ObjectListView import ObjectListView, ColumnDefn, OLVEvent OvlCheckEvent, EVT_OVL_CHECK_EVENT = wx.lib.newevent.NewEvent() class MyOvl(ObjectListView): def SetCheckState(self, modelObject, state): """ This is the same code, just added the event inside """ if self.checkStateColumn is None: return None else: r = self.checkStateColumn.SetCheckState(modelObject, state) #
