// Draggers are graphical objects that typicaly overlay windows and
|
|
// can be shown, hidden, and moved. A default dragger is simply a
|
|
// dotted rectangle XOR'd over the contents of it's window.
|
|
//
|
|
// For bitmap draggers, use the CSprite class.
|
|
//
|
|
// CDragger() creates hidden draggers.
|
|
//
|
|
// ~CDragger() will hide a dragger before it is destroyed.
|
|
//
|
|
// Move() and SetSize() will make sure a dragger gets erased from
|
|
// it's old position and if it was visible, it will be drawn in
|
|
// it's new position.
