126 \brief The QFontDialog class provides a dialog widget for selecting a font. -

127 -

128 A font dialog is created through one of the static getFont() -

129 functions. -

130 -

131 Examples: -

132 -

133 \snippet code/src_gui_dialogs_qfontdialog.cpp 0 -

134 -

135 The dialog can also be used to set a widget's font directly: -

136 \snippet code/src_gui_dialogs_qfontdialog.cpp 1 -

137 If the user clicks OK the font they chose will be used for myWidget, -

138 and if they click Cancel the original font is used. -

139 -
