99 \class QFileDialog -

100 \brief The QFileDialog class provides a dialog that allow users to select files or directories. -

101 \ingroup standard-dialogs -

102 \inmodule QtWidgets -

103 -

104 The QFileDialog class enables a user to traverse the file system in -

105 order to select one or many files or a directory. -

106 -

107 The easiest way to create a QFileDialog is to use the static -

108 functions. On Windows, Mac OS X, KDE and GNOME, these static functions will -

109 call the native file dialog when possible. -

110 -

111 \snippet code/src_gui_dialogs_qfiledialog.cpp 0 -

112 -

113 In the above example, a modal QFileDialog is created using a static -

114 function. The dialog initially displays the contents of the "/home/jana" -

115 directory, and displays files matching the patterns given in the -

116 string "Image Files (*.png *.jpg *.bmp)". The parent of the file dialog -

117 is set to \e this, and the window title is set to "Open Image". -

118 -

119 If you want to use multiple filters, separate each one with -

120 \e two semicolons. For example: -

121 -

122 \snippet code/src_gui_dialogs_qfiledialog.cpp 1 -

123 -

124 You can create your own QFileDialog without using the static -

125 functions. By calling setFileMode(), you can specify what the user must -

126 select in the dialog: -

127 -

128 \snippet code/src_gui_dialogs_qfiledialog.cpp 2 -

129 -

130 In the above example, the mode of the file dialog is set to -

131 AnyFile, meaning that the user can select any file, or even specify a -

132 file that doesn't exist. This mode is useful for creating a -

133 "Save As" file dialog. Use ExistingFile if the user must select an -

134 existing file, or \l Directory if only a directory may be selected. -

135 See the \l QFileDialog::FileMode enum for the complete list of modes. -

136 -

137 The fileMode property contains the mode of operation for the dialog; -

138 this indicates what types of objects the user is expected to select. -

139 Use setNameFilter() to set the dialog's file filter. For example: -

140 -

141 \snippet code/src_gui_dialogs_qfiledialog.cpp 3 -

142 -

143 In the above example, the filter is set to \c{"Images (*.png *.xpm *.jpg)"}, -

144 this means that only files with the extension \c png, \c xpm, -

145 or \c jpg will be shown in the QFileDialog. You can apply -

146 several filters by using setNameFilters(). Use selectNameFilter() to select -

147 one of the filters you've given as the file dialog's default filter. -

148 -

149 The file dialog has two view modes: \l{QFileDialog::}{List} and -

150 \l{QFileDialog::}{Detail}. -

151 \l{QFileDialog::}{List} presents the contents of the current directory -

152 as a list of file and directory names. \l{QFileDialog::}{Detail} also -

153 displays a list of file and directory names, but provides additional -

154 information alongside each name, such as the file size and modification -

155 date. Set the mode with setViewMode(): -

156 -

157 \snippet code/src_gui_dialogs_qfiledialog.cpp 4 -

158 -

159 The last important function you will need to use when creating your -

160 own file dialog is selectedFiles(). -

161 -

162 \snippet code/src_gui_dialogs_qfiledialog.cpp 5 -

163 -

164 In the above example, a modal file dialog is created and shown. If -

165 the user clicked OK, the file they selected is put in \c fileName. -

166 -

167 The dialog's working directory can be set with setDirectory(). -

168 Each file in the current directory can be selected using -

169 the selectFile() function. -

170 -

171 The \l{dialogs/standarddialogs}{Standard Dialogs} example shows -

172 how to use QFileDialog as well as other built-in Qt dialogs. -
