Detailed Description

All graphical output devices and all graphics systems.

Constructor & Destructor Documentation

virtual Fl_Device::~Fl_Device ( )
inlinevirtual

Virtual destructor.

The destructor of Fl_Device must be virtual to make the destructors of derived classes being called correctly on destruction.

Member Function Documentation

virtual const char* Fl_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 in Fl_Display_Device, Fl_Surface_Device, Fl_Xlib_Graphics_Driver, Fl_GDI_Printer_Graphics_Driver, Fl_GDI_Graphics_Driver, Fl_Quartz_Graphics_Driver, Fl_Graphics_Driver, Fl_PostScript_File_Device, Fl_Printer, Fl_Paged_Device, Fl_PostScript_Printer, Fl_Copy_Surface, Fl_System_Printer, Fl_Image_Surface, and Fl_PostScript_Graphics_Driver.

Member Data Documentation

const char * Fl_Device::class_id = "Fl_Device"
static

A string that identifies each subclass of Fl_Device.

Function class_name() applied to a device of this class returns this string.
