Description

The Picture class implements the specific behaviours for displaying images on forms. This class is not instantiable, derivable nor cloneable. The only instances available to the programmer are those automatically generated by HB++ when you place a control on a form.

The image displayed by the control can be defined at design-time or runtime using the Image property. It requires a correctly initialized Bitmap object. The control is sized automatically to accommodate the image and cannot be modified at design-time or runtime with the Move method inherited from the UIComponent class.

The Repaint method redraws the control. It is used to update the display when you modify the image contained in the control dynamically with the methods of the Bitmap object.
