86
87
88The QGroupBox widget provides a group box frame with a title.
89<p>
90
91
92
93<p> A group box provides a frame, a title and a keyboard shortcut, and
94displays various other widgets inside itself. The title is on top,
95the keyboard shortcut moves <a href="focus.html#keyboard-focus">keyboard focus</a> to one of the group
96box's child widgets, and the child widgets are usually laid out
97horizontally (or vertically) inside the frame.
98<p> The simplest way to use it is to create a group box with the
99desired number of columns (or rows) and orientation, and then just
100create widgets with the group box as parent.
101<p> It is also possible to change the <a href="#orientation">orientation</a>() and number of
102<a href="#columns">columns</a>() after construction, or to ignore all the automatic
103layout support and manage the layout yourself. You can add 'empty'
104spaces to the group box with <a href="#addSpace">addSpace</a>().
105<p> QGroupBox also lets you set the <a href="#title">title</a>() (normally set in the
106constructor) and the title's <a href="#alignment">alignment</a>().
107<p> You can change the spacing used by the group box with
108<a href="#setInsideMargin">setInsideMargin</a>() and <a href="#setInsideSpacing">setInsideSpacing</a>(). To minimize space
109consumption, you can remove the right, left and bottom edges of
110the frame with <a href="#setFlat">setFlat</a>().

117Constructs a group box widget with no title.
118<p> The <em>parent</em> and <em>name</em> arguments are passed to the <a href="qwidget.html">QWidget</a>

120<p> This constructor does not do automatic layout.

127<p> This constructor does not do automatic layout.

131Constructs a group box with no title. Child widgets will be
132arranged in <em>strips</em> rows or columns (depending on <em>orientation</em>).
133<p> The <em>parent</em> and <em>name</em> arguments are passed to the <a href="qwidget.html">QWidget</a>

137</h3>
138Constructs a group box titled <em>title</em>. Child widgets will be
139arranged in <em>strips</em> rows or columns (depending on <em>orientation</em>).

145Destroys the group box.
146
147<h3 class=fn>void <a name="addSpace"></a>QGroupBox::addSpace ( int&nbsp;size )
148</h3>
149Adds an empty cell at the next free position. If <em>size</em> is
150greater than 0, the empty cell takes <em>size</em> to be its fixed width

152<a href="qt.html#Orientation-enum">Vertical</a>).
153<p> Use this method to separate the widgets in the group box or to
154skip the next free cell. For performance reasons, call this method
155after calling <a href="#setColumnLayout">setColumnLayout</a>() or by changing the <a href="#columns-prop">QGroupBox::columns</a> or <a href="#orientation-prop">QGroupBox::orientation</a> properties. It is
156generally a good idea to call these methods first (if needed at
157all), and insert the widgets and spaces afterwards.

206Changes the layout of the group box. This function is only useful
207in combination with the default constructor that does not take any
208layout information. This function will put all existing children

210this function after children have been inserted. Sets the number
211of columns or rows to be <em>strips</em>, depending on <em>direction</em>.

247
248<hr><h2>Property Documentation</h2>
249<h3 class=fn>Alignment <a name="alignment-prop"></a>alignment</h3>
250<p>This property holds the alignment of the group box title.
251<p>The title is always placed on the upper frame line. The horizontal
252alignment can be specified by the alignment parameter.
253<p> The alignment is one of the following flags:
254<ul>
255<li> <a href="qt.html#AlignmentFlags-enum">AlignAuto</a> aligns the title according to the language,
256usually to the left.
257<li> <a href="qt.html#AlignmentFlags-enum">AlignLeft</a> aligns the title text to the left.
258<li> <a href="qt.html#AlignmentFlags-enum">AlignRight</a> aligns the title text to the right.
259<li> <a href="qt.html#AlignmentFlags-enum">AlignHCenter</a> aligns the title text centered.
260</ul>
261<p> The default alignment is <a href="qt.html#AlignmentFlags-enum">AlignAuto</a>.
262<p> <p>See also <a href="qt.html#AlignmentFlags-enum">Qt::AlignmentFlags</a>.
263
264<p>Set this property's value with <a href="#setAlignment">setAlignment</a>() and get this property's value with <a href="#alignment">alignment</a>().
265<h3 class=fn>bool <a name="checkable-prop"></a>checkable</h3>
266<p>This property holds whether the group box has a checkbox in its title.
267<p>If this property is TRUE, the group box has a checkbox. If the
268checkbox is checked (which is the default), the group box's
269children are enabled.
270<p> <a href="#setCheckable">setCheckable</a>() controls whether or not the group box has a
271checkbox, and <a href="#isCheckable">isCheckable</a>() controls whether the checkbox is
272checked or not.
273
274<p>Set this property's value with <a href="#setCheckable">setCheckable</a>() and get this property's value with <a href="#isCheckable">isCheckable</a>().
275<h3 class=fn>bool <a name="checked-prop"></a>checked</h3>
276<p>This property holds whether the group box's checkbox is checked.
277<p>If the group box has a check box (see <a href="#isCheckable">isCheckable</a>()), and the
278check box is checked (see <a href="#isChecked">isChecked</a>()), the group box's children
279are enabled. If the checkbox is unchecked the children are
280disabled.
281
282<p>Set this property's value with <a href="#setChecked">setChecked</a>() and get this property's value with <a href="#isChecked">isChecked</a>().
283<h3 class=fn>int <a name="columns-prop"></a>columns</h3>
284<p>This property holds the number of columns or rows (depending on <a href="#orientation-prop">QGroupBox::orientation</a>) in the group box.
285<p>Usually it is not a good idea to set this property because it is
286slow (it does a complete layout). It is best to set the number
287of columns directly in the constructor.
288
289<p>Set this property's value with <a href="#setColumns">setColumns</a>() and get this property's value with <a href="#columns">columns</a>().
290<h3 class=fn>bool <a name="flat-prop"></a>flat</h3>
291<p>This property holds whether the group box is painted flat or has a frame.
292<p>By default a group box has a surrounding frame, with the title
293being placed on the upper frame line. In flat mode the right, left
294and bottom frame lines are omitted, and only the thin line at the
295top is drawn.
296<p> <p>See also <a href="#title-prop">title</a>.
297
298<p>Set this property's value with <a href="#setFlat">setFlat</a>() and get this property's value with <a href="#isFlat">isFlat</a>().
299<h3 class=fn><a href="qt.html#Orientation-enum">Orientation</a> <a name="orientation-prop"></a>orientation</h3>
300<p>This property holds the group box's orientation.
301<p>A horizontal group box arranges it's children in columns, while a
302vertical group box arranges them in rows.
303<p> Usually it is not a good idea to set this property because it is
304slow (it does a complete layout). It is better to set the
305orientation directly in the constructor.
306
307<p>Set this property's value with <a href="#setOrientation">setOrientation</a>() and get this property's value with <a href="#orientation">orientation</a>().
308<h3 class=fn><a href="qstring.html">QString</a> <a name="title-prop"></a>title</h3>
309<p>This property holds the group box title text.
310<p>The group box title text will have a focus-change keyboard
311accelerator if the title contains &amp;, followed by a letter.
312<p> <pre>
313 g-&gt;setTitle( "&amp;User information" );
314 </pre>
315
316This produces "<u>U</u>ser information"; Alt+U moves the <a href="focus.html#keyboard-focus">keyboard focus</a> to the group box.
317<p> There is no default title text.
318
319<p>Set this property's value with <a href="#setTitle">setTitle</a>() and get this property's value with <a href="#title">title</a>().
