Detailed Description

This subclass displays the "on" state by turning on a light, rather than drawing pushed in. The shape of the "light" is initially set to FL_DOWN_BOX. The color of the light when on is controlled with selection_color(), which defaults to FL_YELLOW.

Buttons generate callbacks when they are clicked by the user. You control exactly when and how by changing the values for type() and when().

Member Function Documentation

void Fl_Light_Button::draw

(

)

[protected, virtual]

Draws the widget. Never call this function directly. FLTK will schedule redrawing whenever needed. If your widget must be redrawn as soon as possible, call redraw() instead.

Override this function to draw your own widgets.

If you ever need to call another widget's draw method from within your own draw() method, e.g. for an embedded scrollbar, you can do it (because draw() is virtual) like this:

        Fl_Widget *s = &scroll;         // scroll is an embedded Fl_Scrollbar
        s->draw();                      // calls Fl_Scrollbar::draw()

Reimplemented from Fl_Button.

int Fl_Light_Button::handle

(

int

event

)

[virtual]

Handles the specified event. You normally don't call this method directly, but instead let FLTK do it when the user interacts with the widget.

When implemented in a widget, this function must return 0 if the widget does not use the event or 1 otherwise.

Most of the time, you want to call the inherited handle() method in your overridden method so that you don't short-circuit events that you don't handle. In this last case you should return the callee retval.

Parameters:

[in]

event

the kind of event received

Return values:

0	if the event was not used or understood
1	if the event was used and can be deleted
