Detailed Description

A display to which the computer can draw.

When the program begins running, an Fl_Display_Device instance has been created and made the current drawing surface. There is no need to create any other object of this class.

Member Function Documentation

class_name()

const char * Fl_Display_Device::class_name ( )

inlinevirtual

Returns the name of the class of this object.

Use of the class_name() function is discouraged because it will be removed from future FLTK versions.

The class of an instance of an Fl_Device subclass can be checked with code such as:

if ( instance->class_name() == Fl_Printer::class_id ) { ... }

Reimplemented from Fl_Device.
