93 \class QFileDialog |
|
94 \brief The QFileDialog class provides a dialog that allow users to select files or directories. |
|
95 \ingroup standard-dialogs |
|
96 |
|
97 |
|
98 The QFileDialog class enables a user to traverse the file system in |
|
99 order to select one or many files or a directory. |
|
100 |
|
101 The easiest way to create a QFileDialog is to use the static |
|
102 functions. On Windows, Mac OS X, KDE and GNOME, these static functions will |
|
103 call the native file dialog when possible. |
|
104 |
|
105 \snippet doc/src/snippets/code/src_gui_dialogs_qfiledialog.cpp 0 |
|
106 |
|
107 In the above example, a modal QFileDialog is created using a static |
|
108 function. The dialog initially displays the contents of the "/home/jana" |
|
109 directory, and displays files matching the patterns given in the |
|
110 string "Image Files (*.png *.jpg *.bmp)". The parent of the file dialog |
|
111 is set to \e this, and the window title is set to "Open Image". |
|
112 |
|
113 If you want to use multiple filters, separate each one with |
|
114 \e two semicolons. For example: |
|
115 |
|
116 \snippet doc/src/snippets/code/src_gui_dialogs_qfiledialog.cpp 1 |
|
117 |
|
118 You can create your own QFileDialog without using the static |
|
119 functions. By calling setFileMode(), you can specify what the user must |
|
120 select in the dialog: |
|
121 |
|
122 \snippet doc/src/snippets/code/src_gui_dialogs_qfiledialog.cpp 2 |
|
123 |
|
124 In the above example, the mode of the file dialog is set to |
|
125 AnyFile, meaning that the user can select any file, or even specify a |
|
126 file that doesn't exist. This mode is useful for creating a |
|
127 "Save As" file dialog. Use ExistingFile if the user must select an |
|
128 existing file, or \l Directory if only a directory may be selected. |
|
129 See the \l QFileDialog::FileMode enum for the complete list of modes. |
|
130 |
|
131 The fileMode property contains the mode of operation for the dialog; |
|
132 this indicates what types of objects the user is expected to select. |
|
133 Use setNameFilter() to set the dialog's file filter. For example: |
|
134 |
|
135 \snippet doc/src/snippets/code/src_gui_dialogs_qfiledialog.cpp 3 |
|
136 |
|
137 In the above example, the filter is set to \c{"Images (*.png *.xpm *.jpg)"}, |
|
138 this means that only files with the extension \c png, \c xpm, |
|
139 or \c jpg will be shown in the QFileDialog. You can apply |
|
140 several filters by using setNameFilters(). Use selectNameFilter() to select |
|
141 one of the filters you've given as the file dialog's default filter. |
|
142 |
|
143 The file dialog has two view modes: \l{QFileDialog::}{List} and |
|
144 \l{QFileDialog::}{Detail}. |
|
145 \l{QFileDialog::}{List} presents the contents of the current directory |
|
146 as a list of file and directory names. \l{QFileDialog::}{Detail} also |
|
147 displays a list of file and directory names, but provides additional |
|
148 information alongside each name, such as the file size and modification |
|
149 date. Set the mode with setViewMode(): |
|
150 |
|
151 \snippet doc/src/snippets/code/src_gui_dialogs_qfiledialog.cpp 4 |
|
152 |
|
153 The last important function you will need to use when creating your |
|
154 own file dialog is selectedFiles(). |
|
155 |
|
156 \snippet doc/src/snippets/code/src_gui_dialogs_qfiledialog.cpp 5 |
|
157 |
|
158 In the above example, a modal file dialog is created and shown. If |
|
159 the user clicked OK, the file they selected is put in \c fileName. |
|
160 |
|
161 The dialog's working directory can be set with setDirectory(). |
|
162 Each file in the current directory can be selected using |
|
163 the selectFile() function. |
|
164 |
|
165 The \l{dialogs/standarddialogs}{Standard Dialogs} example shows |
|
166 how to use QFileDialog as well as other built-in Qt dialogs. |

1858 current directory and a default caption will be used respectively. |
|
1859 |
|
1860 The \a options argument holds various options about how to run the dialog, |
|
1861 see the QFileDialog::Option enum for more information on the flags you can |
|
1862 pass. To ensure a native file dialog, \l{QFileDialog::}{ShowDirsOnly} must |
|
1863 be set. |
|
1864 |
|
1865 On Windows and Mac OS X, this static function will use the native file |
|
1866 dialog and not a QFileDialog. On Windows CE, if the device has no native |
|
1867 file dialog, a QFileDialog will be used. |
|
1868 |
|
1869 On Unix/X11, the normal behavior of the file dialog is to resolve and |
|
1870 follow symlinks. For example, if \c{/usr/tmp} is a symlink to \c{/var/tmp}, |
|
1871 the file dialog will change to \c{/var/tmp} after entering \c{/usr/tmp}. If |
|
1872 \a options includes DontResolveSymlinks, the file dialog will treat |
|
1873 symlinks as regular directories. |
|
1874 |
|
1875 On Windows the dialog will spin a blocking modal event loop that will not |
|
1876 dispatch any QTimers, and if \a parent is not 0 then it will position the |
|
1877 dialog just below the parent's title bar. |
|
1878 |
|
1879 \warning Do not delete \a parent during the execution of the dialog. If you |
|
1880 want to do this, you should create the dialog yourself using one of the |
|
1881 QFileDialog constructors. |
