<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"><tt>Fl_Browser</tt></a> for methods to add
|
|
and remove lines from the browser.

<h4><a name="Fl_Hold_Browser.Fl_Hold_Browser">Fl_Hold_Browser::Fl_Hold_Browser(int x, int y, int w, int h, const char *label = 0)</a></h4>
|
|
|
|
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>.
|
|
|
|
<h4><a name="Fl_Hold_Browser.~Fl_Hold_Browser">virtual Fl_Hold_Browser::~Fl_Hold_Browser()</a></h4>
|
|
|
|
The destructor <i>also deletes all the items in the list</i>.
|
|
|
|
<h4><a name="Fl_Hold_Browser.deselect">int Fl_Browser::deselect()</a></h4>
|
|
|
|
Same as <tt>value(0)</tt>.
|
|
|
|
<h4><a name="Fl_Hold_Browser.select">int Fl_Browser::select(int,int=1)<br>
|
|
int Fl_Browser::selected(int) const</a></h4>
|
|
|
|
You can use these for compatibility with
|
|
<a href="#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.
