<H3>Description</H3>
|
|
The <TT>Fl_Hold_Browser</TT> class is a subclass of <TT>Fl_Browser</TT>
|
|
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 <TT>when()</TT>.
|
|
<P>See <A href=Fl_Browser.html#Fl_Browser><TT>Fl_Browser</TT></A> for
|
|
methods to add and remove lines from the browser. </P>

Creates a new <TT>Fl_Hold_Browser</TT> widget using the given
|
|
position, size, and label string. The default boxtype is <TT>FL_DOWN_BOX</TT>

.

The destructor <I>also deletes all the items in the list</I>.

You can use these for compatibility with <A href=Fl_Multi_Browser.html#Fl_Multi_Browser>
|
|
<TT>Fl_Multi_Browser</TT></A>. If you turn on the selection of more
|
|
than one line the results are unpredictable.
|
|
<H4><A name=Fl_Hold_Browser.value>int Fl_Browser::value() const
|
|
<BR> void Fl_Browser::value(int)</A></H4>
|
|
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. </BODY></HTML>
