105 \class QLabel -

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

107 -

108 \ingroup basicwidgets -

109 \inmodule QtWidgets -

110 -

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

112 interaction functionality is provided. The visual appearance of -

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

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

115 -

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

117 -

118 \table -

119 \header \li Content \li Setting -

120 \row \li Plain text -

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

122 \row \li Rich text -

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

124 \row \li A pixmap -

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

126 \row \li A movie -

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

128 \row \li A number -

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

130 the number to plain text. -

131 \row \li Nothing -

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

133 by clear(). -

134 \endtable -

135 -

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

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

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

139 markup. You may want to call -

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

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

142 displaying data loaded from the Web). -

143 -

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

145 previous content is cleared. -

146 -

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

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

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

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

151 -

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

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

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

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

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

157 side of the label): -

158 -

159 \snippet code/src_gui_widgets_qlabel.cpp 0 -

160 -

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

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

163 -

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

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

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

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

168 -

169 \snippet code/src_gui_widgets_qlabel.cpp 1 -

170 -

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

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

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

174 mnemonic would emulate a button click. -
