wx.checkbox and wx.combo.comboctrl

[zhengqing]

Hi, 

   I would like to combine with wx.combo.comboctrl and wx.checkbox to realize a function like wx.combobox with multi-selection.

   I am not sure how to do that, need help!

   or will wx.popwindow + wx.checkbox combination be a better choice?

Regards!

Perhaps ComboCtrl with a CheckListBox popup, or with a wx.ListCtrl plus
CheckListCtrlMixin if you need more than one column.

Sorry, I don't understand your question.

Sorry!

I mean I can't control the size of the checklistbox in combo control, no matter how I set the size.

And in the function bellow:

     def Create(self, parent):
        self.checklistbox 

what is self and parent?

cc = wx.combo.ComboCtrl(self, size = (250, -1))
tcp = CheckboxComboPopup()
cc.SetPopupControl(tcp)

It looks like checklistbox is not attribute of cc and tcp, how can I add items, I tried create a method for adding new items, but it doesn't work?

def Additems(self, list):

     # list = ['zeor', 'one']

     for item in list:

          self.checklistbox.append(item)

tcp.Additems(list)

And this doesn't work!

Please help!

Regards!

Like usual self is an instance of the class that the method is a member
of, in this case the ComboPopup. Parent is the widget that should be
used as the parent of the widget that is created.

The Create method is not called until after the SetPopupControl method
above, so checklistbox does not exist until then. But after that point
in the code you should be able to use checklistbox (or call a method
that uses it) without problems.

Thank you very much! problem solved!

Then another problem is that I can't set the size as shown in the figure.

Do you override the GetAdjustedSize method in your ComboPopup class?
