I have tended to only use the "My" prefix to classes that are imported
gambas objects i'm re-writing to suit my needs.
(like importing the Message.class and just renaming to MyMessage.class to
stop conflicts)
(Ben gets unknowingly credited as a co-writer for most of my applications
:) lol )

i'm not sure i've hit a reserved word here though.
problem has been using the hidden property Me._Container
without using Me._Container i as not getting the parent class using
Object.Parent(Me) i was getting it's first Child object the scrollview plus
other glitches that using Me._Container fixed.
I guess something (in gtk) is not passing a signal across the objects
properly like qt is.


i love the tricks you can do with names though :)
i have some compound controls where all the objects including the container
all use the same event name.
eg.
$hview = New ScrollView(Me) As "View"
$hButton=New Button($hView) As "View"
$hLabel =New Label($hView) As "View"

Public Sub View_Draw()
If Not Object.Is(Last, "ScrollView") Then Return  ' only do Draw events for
main container

End

Public Sub View_MouseDown()
' Catch mouse up events from all controls as one event

End

Seems to work a treat :)
