[Gambas-user] How to extend properties of classes

[richard terry]

I've used the code in CCoolButton to construct an 'outlook style' side bar 
(like in gambas itself), but want a couple of extra properties.

I want to be able to have a popup menu (done that and works) which allows the 
user to change the font size on the buttons.

I did fiddle and try and create Font_Read and Font_Write in the file (by 
coping the structure of the other entries), but it comes up 'null object', so 
I wondered if someone could quickly explain how one extends the properties of 
an object like this. 

Tried something like adding this to the file:

PRIVATE SUB Font_Write(Value AS String)

 ' $hLabel.Font = Value

END
 PRIVATE FUNCTION Font_Read() AS String
  '  hFont = $hLabel.Font
   RETURN $hLabel.Font
 
 END

Hope that makes sense as I don't understand what I'm doing.

Regards

Richard
