DataViewModel Cleared() problem on GTK

wxPython Users
1

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.
