DOH! I should have thought of that. <insert lame excuse here> Thanks!

Either I've found a bug, or I'm not doing something right. The doc says:

"To provide the icons of your component controls, you must create a 
/control directory at the root of your project, and put one PNG file for 
each control icon in it.

The name of a control icon must be the class name of the control in 
lower case with the .png extension."

I tried that but it just shows a black question mark in the IDE panel 
when I load the component. The component itself works as expected. Are 
there any other requirements needed of the icon? I'm currently using a 
32 x 32 PNG file, named in all lowercase the same as the component. I'm 
running Gambas3 on Ubuntu 9.10.

Am I allowed to use *optional* arguments in the _new sub of the 
component? Or am I not suppose to pass arguments to _new?

I know I have to pass the name of the parent container when I use it at 
runtime. I currently have it working using arguments in the _new sub and 
passing the parent name at the end of the argument list. However, the 
last argument I was using is *optional*. If I leave the optional 
argument empty, the IDE says the parent name is 'unexpected'. If I pass 
Null as the optional argument just prior to the parent name, naturally 
it's the wrong data type for the argument. I'm probably missing 
something obvious again. Go ahead and smack me.
