[Pythoncard-users] notebook/grid/initialize problem

[Bo G. <bo...@sy...>]

I am working with TestNotebook, and am trying to create pages and 
populate the pages in the pages using a persistent dictionary. One of 
the properties in one of the pages is a wxGrid. The grid creation 
happens in on_initialize for the page:

class FileSpecsWin(model.PageBackground):
   
    def on_initialize(self, event):
        self.fileGrid = wx.grid.Grid(name='fileGrid', parent=self.panel,
            pos=wx.Point(21, 64), size=wx.Size(400, 390), style=0)
        self.fileGrid.SetRowLabelSize(40)
        self.fileGrid.SetColLabelSize(17)
...etc

the method which adds the page and populates the grid looks like this:

class TestNotebook(model.Background):

...other methods...

    def open_projfile(self):
        try:
            projectFileRef = shelve.open(self.projectFile)
        except IOError:
            result = dialog.alertDialog(self,'File %s could not be 
opened - try again' % (self.projectFile), 'Error')
        else:
            if projectFileRef.has_key('File1Window'):
                self.file1Win = 
model.childWindow(self.components.notebook, FileSpecsWin)
                self.components.notebook.AddPage(self.file1Win, 'File 1 
Specs', True)
                (self.file1Win.components.textFilePath.text,
                 self.file1Win.components.buttonImport.enabled,
                 self.file1Win.components.buttonLoad.enabled) = 
projectFileRef['File1Window']
                if projectFileRef.has_key('File1GridData'):
                    grid_data = projectFileRef['File1GridData']
                    self.set_grid_data(grid_data, self.file1Win.fileGrid)

But, the grid doesn't exist when this method attempts to populate it. I 
get an error like this:

AttributeError: 'FileSpecsWin' object has no attribute 'fileGrid'

I thought this might have to do with stacking method calls, so I tried 
wx.CallAfter(self.set_grid_data, grid_data, self.file1Win.fileGrid), but 
that didn't work. I could use some sage advice at this point.
Thanks.
