class Fl_Hold_Browser : public Fl_Browser

This is a subclass of Fl_Browser which lets the user select a single item, or no items by clicking on the empty space. As long as the mouse button is held down the item pointed to by it is highlighted, and this highlighting remains on when the mouse button is released. Normally the callback is done when the user releases the mouse, but you can change this with when().

See Fl_Browser for methods to add and remove lines from the browser.

Fl_Hold_Browser::Fl_Hold_Browser(int x,int y,int w,int h,const char *l)

Constructor.

uchar Fl_Widget::when() const;
void Fl_Widget::when(uchar);

Controls when callbacks are done. The following values are useful, the default value is FL_WHEN_RELEASE:

uchar Fl_Browser::selection_color() const ;
void Fl_Browser::selection_color(n);

The color to draw the background of selected lines. Lines that aren't selected use color().

int Fl_Browser::value() const ;
void Fl_Browser::value(int) ;

Set or get which line is selected. This returns zero if no line is selected, be aware that this can happen in a callback.

int Fl_Browser::deselect();

Same as Fl_Browser::value(0).

int Fl_Browser::select(int,int=1);
int Fl_Browser::selected(int) const ;

You can use these for compatibility with the Fl_Multi_Browser. However if you turn on the selection of more than one line the results are unpredictable.
