Hi Rui,

all you then need to do is allocate the userarea that should be attached to your userarea fields.

So if you defined a UA in ResEdit with the ID "IDC_RUISAREA" for example, you need to call

ua = new(MyUserArea,IDC_RUISAREA,this);

Mmmmm, I will give it a try. What I can't understand is that is the "this" variable.

Hey Rui,

if you look into the COFFEE docs you can see the constructor of the class:

GeUserArea([int] id, [GeBaseDialog] dialog);

id = IDC_RUISAREA
and
dialog = this

"this" is the pointer of the class it´s used in. (in this case a pointer to your dialog)

I tried to use:

  
user_x=GeUserArea(X_PIC,this);  

But I keep getting this error:

(7) CLASS is not a function

What can be wrong with it?

You have to use 'new' on a class to call the constructor in COFFEE:

user_x = new(GeUserArea(X_PIC,this));

If you are going to create the GeUserArea programatically and attach to the dialog, you may need to derive your own class and use the code as in the example. My experience with this stuff in COFFEE is limited, so I usually stick with the examples and other existing code when possible.

No, I'm not going to create a User Area programatically. I simply want to have access to user areas I already defined with Resedit in a dialog resorce. But I think this is excessivelly complicated

In ResEdit you only define the UserArea gui, but that won´t create a GeUserArea instance for you. You have to derive your own class from the GeUserArea Base class to get access to it. There is no way around it afaik.

Oh, ok... so I still have to derive the class. Damn, its really confusing. No wonder so many people run away from programming
I will give it a try. Probably I will only have time tomorrow. Thank you both for the time and effort into helping me out. I will report my success/failure

Where must I add the

In CreateLayout().

Try it like this:

  
PluginDialog::CreateLayout()  
{  
var retval = LoadDialogResource(ALIGNER, PLUGIN_RES, 0);  
ua = new(MyUserArea, id, this);  
return reval;  
}  

If your user area is defined in the Dialog Resource, then you don't need to AddUserArea(). If not, you must.

Don't forget to set the id to the correct value!
