Description

+ Emulation of the Forms "free" widget. This emulation allows the free +demo to run, and appears to be useful for porting programs written in +Forms which use the free widget or make subclasses of the Forms +widgets. +

There are five types of free, which determine when the handle +function is called:

+#define FL_NORMAL_FREE		1
+#define FL_SLEEPING_FREE	2
+#define FL_INPUT_FREE		3
+#define FL_CONTINUOUS_FREE	4
+#define FL_ALL_FREE		5
+

An FL_INPUT_FREE accepts FL_FOCUS events. A FL_CONTINUOUS_FREE sets +a timeout callback 100 times a second and provides a FL_STEP event, +this has obvious detrimental effects on machine performance. +FL_ALL_FREE does both. FL_SLEEPING_FREE are deactivated.

Methods

Fl_Free
~Fl_Free

Fl_Free(uchar type, int, int, int, int, +const char*l, FL_HANDLEPTR hdl)

+ The constructor takes both the type and the handle + function. The handle function should be declared as follows: +

+int
+handle_function(Fl_Widget *w,
+                int       event,
+	        float     event_x,
+		float     event_y,
+		char      key)
+

+ This function is called from the the handle() method in +response to most events, and is called by the draw() method. +The event argument contains the event type: +

+// old event names for compatability:
+#define FL_MOUSE		FL_DRAG
+#define FL_DRAW			0
+#define FL_STEP			9
+#define FL_FREEMEM		12
+#define FL_FREEZE		FL_UNMAP
+#define FL_THAW			FL_MAP
+

virtual Fl_Free::~Fl_Free()

+ The destructor will call the handle function with the event +FL_FREE_MEM. -- cgit v1.3.1
