Member Function Documentation

◆ class_name()

const char * Fl_Xlib_Graphics_Driver::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 ) { ... }
