RE: [OpenMap Users] Create own OMGraphic

FYI, that's because OMGraphicList subclasses OMGraphic and therefore has
all the methods of an OMGraphic. This is done so that you can have a
linked list of OMGraphics. In other words, you can graphic lists that
contain both OMGraphics and OMGraphicLists. It is basically a tree
structure, much like windows explorer or KDE Konqueror.

Hi Bryan -
 
Check out OMGraphicList. It acts as a OMGraphic (in that it has a render
and generate method) but allows you to add multiple OMGraphic objects to
it to group them together.

Subject: [OpenMap Users] Create own OMGraphic

Hello,

I am trying to create my own OMGraphic that contains an OMCircle, OMLine
, OMRect and OMText. I tried and failed. So, I created a class that
adds all of the OMGraphics to a graphic list. Then I use this graphic
list throughout the rest of my code. So I am wondering if anyone can
point me somewhere or help me create this OMGraphic, so that it is a
single OMGraphic? So when I create an object of my class OMnewgraphic.
It creates a single OMGraphic object, instead of an object with an
OMGraphicList. I've looked around and there doesn't seem to be any
documentation on how to do this. Is there any sample code I could look
at, or am I missing something?

-Bryan
