Dear all,
in an application window (subwindow of a Notebook-control) I'm trying to
do the following:
1. Create a StaticText control kind of "Please wait until processing has
finished"
2. Do some processing (e.g. vacuuming an sqlite database)
3. Create a 2nd StaticText control with the message "processing finished"
Naïvely I would expect following behavior:
1st control appears
data processing step runs
after finishing processing the 2nd control appears
but actually the order in execution seems to be a different one:
computer is doing heavy processing
1st control appears
2nd control appears immediately after the 1st without any visible delay
Could someone give a hint, how to change the seeming behavior into the
intended one?
Thanks in advance Josef
P.S.:
here is the actual code snippet:
def OnVacuum(self,event):
panel=Ntab(self.desktop,"Compact")
message1=wx.StaticText(panel,-1,"Please wait, database is being
compacted.",(20,10))
self.SetCursor(wx.StockCursor(wx.CURSOR_WAIT))
con=sqlite3.connect(dbname)
cur=con.cursor()
cur.execute("VACUUM;")
cur.close()
con.close()
self.SetCursor(wx.StockCursor(wx.CURSOR_DEFAULT))
message2=wx.StaticText(panel,-1,"Compacting database has now
finished",(20,30))
Ntab is a class derived from wx.Panel and a tab of the abovementioned
wx.Notebook control
