Hi all,
I use PMW 1.2 on Python 2.3.0 on Win2k.
I've created a dialog that looks like so:
+----------------------+
Name | |
+----------------------+
+----------------------+
Caption text head | |
+----------------------+
+----------------------+
# Digits w/o sign | |
+----------------------+
+----------------------+
Caption text tail | |
+----------------------+
+--+
Is editable | |
+--+
+--------------------+-+
Parameter name | |V| Drop-down.
+--------------------+-+
I pull down the drop-down control, select an item, the drop-down closes
and - vanishes. All controls have vanished. After half a second or so the
first one reappears, but w/o its label 'Name'.
The other ones reapper if I click onto the pane where they are supposed to
be. They also reapper if I change to an other app and then come back again.
I guess this is because a window update is issued by the OS.
What do I miss?
Many thanks in advance and kind regards
Franz GEIGER

existing
Parameter name | |V| parameters, i.e. you have to
first
