111 \class QLabel -

112 \brief The QLabel widget provides a text or image display. -

113 -

114 \ingroup basicwidgets -

115 \inmodule QtWidgets -

116 -

117 QLabel is used for displaying text or an image. No user -

118 interaction functionality is provided. The visual appearance of -

119 the label can be configured in various ways, and it can be used -

120 for specifying a focus mnemonic key for another widget. -

121 -

122 A QLabel can contain any of the following content types: -

123 -

124 \table -

125 \header \li Content \li Setting -

126 \row \li Plain text -

127 \li Pass a QString to setText(). -

128 \row \li Rich text -

129 \li Pass a QString that contains rich text to setText(). -

130 \row \li A pixmap -

131 \li Pass a QPixmap to setPixmap(). -

132 \row \li A movie -

133 \li Pass a QMovie to setMovie(). -

134 \row \li A number -

135 \li Pass an \e int or a \e double to setNum(), which converts -

136 the number to plain text. -

137 \row \li Nothing -

138 \li The same as an empty plain text. This is the default. Set -

139 by clear(). -

140 \endtable -

141 -

142 \warning When passing a QString to the constructor or calling setText(), -

143 make sure to sanitize your input, as QLabel tries to guess whether it -

144 displays the text as plain text or as rich text, a subset of HTML 4 -

145 markup. You may want to call -

146 setTextFormat() explicitly, e.g. in case you expect the text to be in -

147 plain format but cannot control the text source (for instance when -

148 displaying data loaded from the Web). -

149 -

150 When the content is changed using any of these functions, any -

151 previous content is cleared. -

152 -

153 By default, labels display \l{alignment}{left-aligned, vertically-centered} -

154 text and images, where any tabs in the text to be displayed are -

155 \l{Qt::TextExpandTabs}{automatically expanded}. However, the look -

156 of a QLabel can be adjusted and fine-tuned in several ways. -

157 -

158 The positioning of the content within the QLabel widget area can -

159 be tuned with setAlignment() and setIndent(). Text content can -

160 also wrap lines along word boundaries with setWordWrap(). For -

161 example, this code sets up a sunken panel with a two-line text in -

162 the bottom right corner (both lines being flush with the right -

163 side of the label): -

164 -

165 \snippet code/src_gui_widgets_qlabel.cpp 0 -

166 -

167 The properties and functions QLabel inherits from QFrame can also -

168 be used to specify the widget frame to be used for any given label. -

169 -

170 A QLabel is often used as a label for an interactive widget. For -

171 this use QLabel provides a useful mechanism for adding an -

172 mnemonic (see QKeySequence) that will set the keyboard focus to -

173 the other widget (called the QLabel's "buddy"). For example: -

174 -

175 \snippet code/src_gui_widgets_qlabel.cpp 1 -

176 -

177 In this example, keyboard focus is transferred to the label's -

178 buddy (the QLineEdit) when the user presses Alt+P. If the buddy -

179 was a button (inheriting from QAbstractButton), triggering the -

180 mnemonic would emulate a button click. -
