<h2>Detailed Description</h2>

<p>The QGroupBox widget provides a group box frame with a title.</p>

<p>A group box provides a frame, a title and a keyboard shortcut, and displays various other widgets inside itself. The title is on top, the keyboard shortcut moves keyboard focus to one of the group box's child widgets.</p>

<p>QGroupBox also lets you set the <a href="qgroupbox.html#title-prop">title</a> (normally set in the constructor) and the title's <a href="qgroupbox.html#alignment-prop">alignment</a>(). If setCheckable(true) is called then the group box is <a href="qgroupbox.html#checkable-prop">isCheckable</a>(), and it can be <a href="qgroupbox.html#checked-prop">setChecked</a>(). Checkable group boxes child widgets are enabled or disabled depending on whether or not the group box is <a href="qgroupbox.html#checked-prop">isChecked</a>().</p>

<p>To minimize space consumption, you can remove the right, left and bottom edges of the frame with <a href="qgroupbox.html#flat-prop">setFlat</a>().</p>

<h2>Property Documentation</h2>

103

<h3 class="fn"><a name="alignment-prop"></a>alignment : <a href="qt.html#AlignmentFlag-enum">Qt::Alignment</a></h3>

104

<p>This property holds the alignment of the group box title.</p>

105

<p>The title is always placed on the upper frame line. The horizontal alignment can be specified by the alignment parameter.</p>

106

<p>The alignment is one of the following flags:</p>

107

<ul>

108

<li><tt>Qt::AlignLeft</tt> aligns the title text to the left.</li>

109

<li><tt>Qt::AlignRight</tt> aligns the title text to the right.</li>

110

<li><tt>Qt::AlignHCenter</tt> aligns the title text centered.</li>

111

</ul>

112

<p>The default alignment is <tt>Qt::AlignLeft</tt>.</p>

113

<p>Access functions:</p>

114

<ul>

115

<li><div class="fn"/><b>Qt::Alignment alignment () const</b></li>

116

<li><div class="fn"/><b>void setAlignment ( int )</b></li>

117

</ul>

118

<p>See also <a href="qt.html#AlignmentFlag-enum">Qt::Alignment</a>.</p>

119

<h3 class="fn"><a name="checkable-prop"></a>checkable : bool</h3>

120

<p>This property holds whether the group box has a checkbox in its title.</p>

121

<p>If this property is true, the group box has a checkbox. If the checkbox is checked (which is the default), the group box's children are enabled.</p>

122

<p>setCheckable() controls whether or not the group box has a checkbox, and isCheckable() controls whether the checkbox is checked or not.</p>

123

<p>Access functions:</p>

124

<ul>

125

<li><div class="fn"/><b>bool isCheckable () const</b></li>

126

<li><div class="fn"/><b>void setCheckable ( bool <i>b</i> )</b></li>

127

</ul>

128

<h3 class="fn"><a name="checked-prop"></a>checked : bool</h3>

129

<p>This property holds whether the group box's checkbox is checked.</p>

130

<p>If the group box has a check box (see <a href="qgroupbox.html#checkable-prop">isCheckable</a>()), and the check box is checked, the group box's children are enabled. If the checkbox is unchecked the children are disabled.</p>

131

<p>Access functions:</p>

132

<ul>

133

<li><div class="fn"/><b>bool isChecked () const</b></li>

134

<li><div class="fn"/><b>void setChecked ( bool <i>b</i> )</b></li>

135

</ul>

136

137

<p>This property holds whether the group box is painted flat or has a frame.</p>

138

<p>By default a group box has a surrounding frame, with the title being placed on the upper frame line. In flat mode the right, left and bottom frame lines are omitted, and only the thin line at the top is drawn.</p>

139

<p>Access functions:</p>

140

<ul>

141

<li><div class="fn"/><b>bool isFlat () const</b></li>

142

<li><div class="fn"/><b>void setFlat ( bool <i>b</i> )</b></li>

143

</ul>

144

<p>See also <a href="qgroupbox.html#title-prop">title</a>.</p>

145

<h3 class="fn"><a name="title-prop"></a>title : <a href="qstring.html">QString</a></h3>

146

<p>This property holds the group box title text.</p>

147

<p>The group box title text will have a focus-change keyboard shortcut if the title contains &, followed by a letter.</p>

148

<pre>  g->setTitle("&User information");</pre>

149

<p>This produces "<u>U</u>ser information"; <b>Alt+U</b> moves the keyboard focus to the group box.</p>

150

<p>There is no default title text.</p>

151

<p>Access functions:</p>

152

<ul>

153

<li><div class="fn"/><b>QString title () const</b></li>

154

<li><div class="fn"/><b>void setTitle ( const QString & )</b></li>

155

</ul>
