Macro Definition Documentation

#define GCCV_ITEM_POS_PROP	(		type,
			member
	)

Value:

public: \
        void Set##member (type val) {   \
                Invalidate ();  \
                m_##member = val;       \
                BoundsChanged ();       \
                Invalidate ();  \
        }       \
        type Get##member (void) const {return m_##member;}      \
private:        \
        type m_##member;

Defines a private member with appropriate get/set methods. This macro should be used when a property change might change the bounds of the item. GCCV_ITEM_POS_PROP((Type,Foo) expands to one private member:

Type m_Foo;

and three public methods:

void SetFoo(Type val);
Type GetFoo();

Calling SetFoo(val) will set the member and invalidate the item bounds.

#define GCCV_ITEM_PROP	(		type,
			member
	)

Value:

public: \
        void Set##member (type val) {   \
                m_##member = val;       \
                Invalidate ();  \
        }       \
        type Get##member (void) const {return m_##member;}      \
private:        \
        type m_##member;

Defines a private member with appropriate get/set methods. This macro should be used when a property change needs a redraw of the item. GCCV_ITEM_PROP((Type,Foo) expands to one private member:

Type m_Foo;

and three public methods:

void SetFoo(Type val);
Type GetFoo();

Calling SetFoo(val) will set the member and invalidate the item.
