Combo Box List in Collapsible Pane not updating

Robert_VERGNES · February 14, 2007, 9:31am

Hello Robin,

···

It took some time but here is the ‘small’ code.

The list of the collapsible pane is not updating.

The wx(statictext and textbox) do update correctly but not the list in the list box.

Any ideas ?

Best Regards,

Robert

Code follows and it is also in attachment - only import if wx:

may be there is a way around or i use comboxo badly ?

Hi Robert,

I tried to have a look at this and found a little code mistake.

AddSpacer(5)

Should be:
AddSpacer((5, 5))

There is also a dependency to "genlog", so I just commented all between PySimpleApp and when the frame is created.

Why are you recreating the controls on the pane each time? Don't you just want to change the choices?

I actually think this has to do with your problem, because if I change the combobox to:
cbx1 = wx.ComboBox(pane, wx.ID_ANY , "default value" , (-1, -1), (-1, -1),labels, wx.CB_DROPDOWN)

Use default size and position I can see two combobox's on your pane.

So, I added this to the beginning of MakePaneContent:

        for child in pane.GetChildren():
            child.Destroy()
               sizer = pane.GetSizer()
        del sizer
