DataViewModel Cleared() problem on GTK

[zliwang]

Hi
When I call DataViewModel's Cleared() method on Linux GTK, it does cause
data model to be reread, but the control is cleared, no view is displayed.
anymore.

The same code works fine on Windows, the view changes based on the new data
model.

Any workaround or if I am doing something wrong? Any help is much
appreciated.

Thanks

have you tried calling Refresh() on the DataViewModel?

thanks for the suggestion. I tried to call the corresponding dataViewCtrl's
refresh() but it make no difference..

Using wxPython's DVC_DataViewModel demo, add self.model.Cleared() at the
end of
the __init__ method of TestPanel:

class TestPanel(wx.Panel):
def __init__(self, parent, log, data=None, model=None):
...
self.model.Cleared()
self.dvc.Refresh()


Save changes and restart demo, the view is gone on Linux GTK. This looks
like a bug.

If you post a sample app file, we can try it out. Personally I've got
Windows 7, XP (2.9.4 and 3.0.1-preview), and Ubuntu 14.04 with
compiled-by-me wxPython 3.0.1.1

This can be easily tested by simply using wxPython's demo
DVC_DataViewModel.

Add self.model.Cleared() at the end ofthe __init__ method of TestPanel:

class TestPanel(wx.Panel):
def __init__(self, parent, log, data=None, model=None):
...
# Add this call
self.model.Cleared() or
wx.CallAfter(self.model.Cleared)

The view will not show. It works on Windows and Mac. I also built wxPthon
3.0.1.1 myself on Fedora.

Agreed. Please create a Trac ticket about it.
