Adding a category

At least one category must be created. Categories and variables are both stored in the one list. A category differs from a variable by having a “space” character as the first symbol of the name. All variables located in the list after a category are considered as belonging to that category.

A category can be added to the list in either of two ways:

Pascal:

frxReport1.Variables[' ' + 'My Category 1'] := Null;

C++:

frxReport1->Variables->Variables[" My Category 1"] = NULL;

or

Pascal:

var

 Category: TfrxVariable;

Category := frxReport1.Variables.Add;

Category.Name := ' ' + 'My category 1';

C++:

TfrxVariable * Category;

Category = frxReport1->Variables->Add();

Category->Name = " My category 1";
