Fl_Browser | +----Fl_Hold_Browser
The Fl_Hold_Browser class 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.
Creates a new Fl_Hold_Browser widget using the given position, size, and label string. The default boxtype is FL_DOWN_BOX.
The destructor also deletes all the items in the list.
Same as value(0).
You can use these for compatibility with Fl_Multi_Browser. If you turn on the selection of more than one line the results are unpredictable.
Set or get which line is selected. This returns zero if no line is selected, so be aware that this can happen in a callback.
