If you want to actually post an event with the existing framework, you must
create a valid wxPython event object and then use wxPython's wxPostEvent or
ProcessEvent. That isn't necessary for your needs as I'll show below.

Since event handlers like your on_menuViewPreviewBrowser_select are just
methods, you can always call them directly, but that is not the same as
posting an event that goes into the queue and if you call a method that way,
you won't have a valid event argument, so it is important that you not try
and use the event attributes. The dbBrowser, saveClipboardBitmap,
radioclient, resourceEditor, and textEditor use this technique. For example,
in saveClipboardBitmap, the openBackground handler calls the file save as
event handler; note that the event is None.

        self.on_menuFileSaveAs_select(None)

It won't work for your example below because you don't want to actually do
everything that is in on_menuViewPreviewBrowser_select.

You mean hides the child window; that's what the code does that you
supplied.

>      def on_menuViewPreviewBrowser_select(self, event):
>          state = self.menuBar.getChecked('menuViewPreviewBrowser')
>          #show or hid the browser child'
>          self.iechild.Show(state)
>          self.configState['browserpreview.visible'] = state
> 
>

>          self.Show(0)

You need a reference to the parent window. If you don't already have that
reference, then use GetParent().

    def doExit(self):
        parent = self.GetParent()
        parent.menuBar.setChecked('menuViewPreviewBrowser', 0)
        parent.configState['browserpreview.visible'] = 0
