wx.checkbox and wx.combo.comboctrl

wxPython Users

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 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.

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

It looks like checklistbox is not attribute of cc and tcp,

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.

Do you override the GetAdjustedSize method in your ComboPopup class?

Hi Robin,
     no, I didn't. From the Demo, I can't tell when this method was
called, and what is the function of this method.
     Now I add this method into the class, but still don't know how it
works, and where those parameter comes from, how to set those
parameters, and when this method was called.

     def GetAdjustedSize(self, minWidth, prefHeight, maxHeight):
         return wx.Size(minWidth, min(150, maxHeight))

     Please help if I would like to learn more about wxpython.
