Still going down the Lostfocus road - I like that as you either select a
record by clicking on it, or abandon selection by clicking elsewhere.
Realised my Lostfocus was on the wrong control! (ie the button, not the
dListBox - changed my code as follows :-
self.AccountLookupbtn = dabo.ui.dButton(self.basePanel, Left=184, Top=78,
Width=40,
Caption="Lookup",OnHit=self.DDLPanel)
def DDLPanel(self, evt):
self.fp = self.FloatingPanel
# Can use floating panel owner property to set position here)
left, top = self.Position
self.fp.Position = (left+184,top+78)
codes, keys = self.PrimaryBizobj.getAccountCodes()
self.AccountCodeDDL = dabo.ui.dListBox(self.fp, Width=60, Height=200,
Left=0, Top=0, ValueMode="Key", Choices = codes, Keys = keys,
OnHit=self.DDLClick,
OnLostFocus=self.DeleteDDL)
wd, ht = self.AccountCodeDDL.Size
self.fp.Size = (wd, ht)
self.fp.Visible = True
self.AccountCodeDDL.Visible = True
def DDLClick(self, evt):
self.PrimaryBizobj.moveToPK(self.AccountCodeDDL.Value)
self.update()
self.DDLKill()
def DeleteDDL(self, evt):
self.DDLKill()
def DDLKill(self):
self.AccountCodeDDL.release()
self.fp.release()
Works correctly, but gives a trace as follows :
C:/Python25/pythonw.exe -u "C:/LBProject/AccountsForm.py"
Traceback (most recent call last):
File "c:\svndabo\dabo\ui\uiwx\dPemMixin.py", line 565, in __onWxLostFocus

13776, in __getattr__
raise PyDeadObjectError(self.attrStr % self._name)
wx._core.PyDeadObjectError: The C++ part of the dListBox object has been
deleted, attribute access no longer allowed.
Any suggestions?
Thanks Rodgy
