<div class="descr">
<h2>Detailed Description</h2>
<p>The Q3ButtonGroup widget organizes <a href="qabstractbutton.html">QAbstractButton</a> widgets in a group.</p>
<p>A button group widget makes it easier to deal with groups of buttons. Each button in a button group has a unique identifier. The button group emits a <a href="q3buttongroup.html#clicked">clicked</a>() signal with this identifier when a button in the group is clicked. This makes a button group particularly useful when you have several similar buttons and want to connect all their <a href="q3buttongroup.html#clicked">clicked</a>() signals to a single slot.</p>
<p>An <a href="q3buttongroup.html#exclusive-prop">exclusive</a> button group switches off all toggle buttons except the one that was clicked. A button group is, by default, non-exclusive. Note that all radio buttons that are inserted into a button group are mutually exclusive even if the button group is non-exclusive. (See <a href="q3buttongroup.html#radioButtonExclusive-prop">setRadioButtonExclusive</a>().)</p>
<p>There are two ways of using a button group:</p>
<ul>
<li>The button group is the parent widget of a number of buttons, i.e. the button group is the parent argument in the button constructor. The buttons are assigned identifiers 0, 1, 2, etc., in the order they are created. A Q3ButtonGroup can display a frame and a title because it inherits <a href="q3groupbox.html">Q3GroupBox</a>.</li>
<li>The button group is an invisible widget and the contained buttons have some other parent widget. In this usage, each button must be manually inserted, using <a href="q3buttongroup.html#insert">insert</a>(), into the button group and given an identifier.</li>
</ul>
<p>A button can be removed from the group with <a href="q3buttongroup.html#remove">remove</a>(). A pointer to a button with a given id can be obtained using <a href="q3buttongroup.html#find">find</a>(). The id of a button is available using <a href="q3buttongroup.html#id">id</a>(). A button can be set <i>on</i> with <a href="q3buttongroup.html#selectedId-prop">setButton</a>(). The number of buttons in the group is returned by <a href="q3buttongroup.html#count">count</a>().</p>

<p>Inserts the <i>button</i> with the identifier <i>id</i> into the button group. Returns the button identifier.</p>
<p>Buttons are normally inserted into a button group automatically by passing the button group as the parent when the button is constructed. So it is not necessary to manually insert buttons that have this button group as their parent widget. An exception is when you want custom identifiers instead of the default 0, 1, 2, etc., or if you want the buttons to have some other parent.</p>
<p>The button is assigned the identifier <i>id</i> or an automatically generated identifier. It works as follows: If <i>id</i> >= 0, this identifier is assigned. If <i>id</i> == -1 (default), the identifier is equal to the number of buttons in the group. If <i>id</i> is any other negative integer, for instance -2, a unique identifier (negative integer <= -2) is generated. No button has an id of -1.</p>
