<h3>Description</h3>
|
|
|
|
The <tt>Fl_Tabs</tt> widget is the "file card tabs" interface that
|
|
allows you to put lots and lots of buttons and switches in a panel, as
|
|
popularized by many toolkits.
|
|
|
|
<p><img src=tabs.gif>
|
|
|
|
<p>Clicking the tab makes a child <tt>visible()</tt> (by calling
|
|
<tt>show()</tt> on it) and all other children are invisible (by calling
|
|
<tt>hide()</tt> on them). Usually the children are <a
|
|
href="#Fl_Group"><tt>Fl_Group<tt></a> widgets containing several
|
|
widgets themselves.
|
|
|
|
<p>Each child makes a card, and it's <tt>label()</tt> is printed on the
|
|
card tab (including the label font and style). The color of that child
|
|
is used to color the card as well. Currently this only draws nicely if
|
|
you set <a href="#Fl_Widget.box"><tt>box()</tt></a> to the default
|
|
<tt>FL_THIN_UP_BOX</tt> or to <tt>FL_FLAT_BOX</tt>, which gets rid of
|
|
the edges drawn on the sides and bottom.
|
|
|
|
<p>The size of the tabs is controlled by the bounding box of the
|
|
children (there should be some space between the children and the edge
|
|
of the <tt>Fl_Tabs</tt>), and the tabs may be placed "inverted" on the
|
|
bottom, this is determined by which gap is larger. It is easiest to
|
|
lay this out in fluid, using the fluid browser to select each child
|
|
group and resize them until the tabs look the way you want them to.

|
<h4><a name="Fl_Tab.Fl_Tab">Fl_Tab::Fl_Tab(int x, int y, int w, int h, const char *label = 0)</a></h4>
|
|
|
|
Creates a new <tt>Fl_Tab</tt> widget using the given position, size, and
|
|
label string. The default boxtype is <tt>FL_THIN_UP_BOX</tt>.
|
|
|
|
<p>Use <a href="#Fl_Group.add"><tt>add(Fl_Widget *)</tt></a> to add
|
|
each child (which is probably itself a <tt>Fl_Group</tt>). The
|
|
children should be sized to stay away from the top or bottom edge of
|
|
the <tt>Fl_Tabs</tt>, which is where the tabs are drawn.
|
|
|
|
<h4><a name="Fl_Tab.~Fl_Tab">virtual Fl_Tab::~Fl_Tab()</a></h4>
|
|
|
|
The destructor <i>also deletes all the children</i>. This allows a
|
|
whole tree to be deleted at once, without having to keep a pointer to all
|
|
the children in the user code. A kludge has been done so the
|
|
<tt>Fl_Tab</tt> and all of it's children can be automatic (local)
|
|
variables, but you must declare the <tt>Fl_Tab</tt> <i>first</i>, so
|
|
that it is destroyed last.
|
|
|
|
<h4><a name="Fl_Tab.value">Fl_Widget* Fl_Tabs::value() const<br>
|
|
int Fl_Tabs::value(Fl_Widget*)</a></h4>
|
|
|
|
Gets or sets the currently visible widget/tab.
