2093 | \class Q3FileDialog
|
---|
2094 | \brief The Q3FileDialog class provides dialogs that allow users to select files or directories.
|
---|
2095 |
|
---|
2096 | \compat
|
---|
2097 |
|
---|
2098 | The Q3FileDialog class enables a user to traverse their file system in
|
---|
2099 | order to select one or many files or a directory.
|
---|
2100 |
|
---|
2101 | The easiest way to create a Q3FileDialog is to use the static
|
---|
2102 | functions. On Windows, these static functions will call the native
|
---|
2103 | Windows file dialog and on Mac OS X, these static function will call
|
---|
2104 | the native Mac OS X file dialog.
|
---|
2105 |
|
---|
2106 | \snippet doc/src/snippets/code/src_qt3support_dialogs_q3filedialog.cpp 0
|
---|
2107 |
|
---|
2108 | In the above example, a modal Q3FileDialog is created using a static
|
---|
2109 | function. The startup directory is set to "/home". The file filter
|
---|
2110 | is set to "Images (*.png *.xpm *.jpg)". The parent of the file dialog
|
---|
2111 | is set to \e this and it is given the identification name - "open file
|
---|
2112 | dialog". The caption at the top of file dialog is set to "Choose a
|
---|
2113 | file". If you want to use multiple filters, separate each one with
|
---|
2114 | \e two semicolons, e.g.
|
---|
2115 | \snippet doc/src/snippets/code/src_qt3support_dialogs_q3filedialog.cpp 1
|
---|
2116 |
|
---|
2117 | You can create your own Q3FileDialog without using the static
|
---|
2118 | functions. By calling setMode(), you can set what can be returned by
|
---|
2119 | the Q3FileDialog.
|
---|
2120 |
|
---|
2121 | \snippet doc/src/snippets/code/src_qt3support_dialogs_q3filedialog.cpp 2
|
---|
2122 |
|
---|
2123 | In the above example, the mode of the file dialog is set to \l
|
---|
2124 | AnyFile, meaning that the user can select any file, or even specify a
|
---|
2125 | file that doesn't exist. This mode is useful for creating a "File Save
|
---|
2126 | As" file dialog. Use \l ExistingFile if the user must select an
|
---|
2127 | existing file or \l Directory if only a directory may be selected.
|
---|
2128 | (See the \l Q3FileDialog::Mode enum for the complete list of modes.)
|
---|
2129 |
|
---|
2130 | You can retrieve the dialog's mode with mode(). Use setFilter() to set
|
---|
2131 | the dialog's file filter, e.g.
|
---|
2132 |
|
---|
2133 | \snippet doc/src/snippets/code/src_qt3support_dialogs_q3filedialog.cpp 3
|
---|
2134 |
|
---|
2135 | In the above example, the filter is set to "Images (*.png *.xpm
|
---|
2136 | *.jpg)", this means that only files with the extension \c png, \c xpm
|
---|
2137 | or \c jpg will be shown in the Q3FileDialog. You can apply
|
---|
2138 | several filters by using setFilters() and add additional filters with
|
---|
2139 | addFilter(). Use setSelectedFilter() to select one of the filters
|
---|
2140 | you've given as the file dialog's default filter. Whenever the user
|
---|
2141 | changes the filter the filterSelected() signal is emitted.
|
---|
2142 |
|
---|
2143 | The file dialog has two view modes, Q3FileDialog::List which simply
|
---|
2144 | lists file and directory names and Q3FileDialog::Detail which
|
---|
2145 | displays additional information alongside each name, e.g. file size,
|
---|
2146 | modification date, etc. Set the mode with setViewMode().
|
---|
2147 |
|
---|
2148 | \snippet doc/src/snippets/code/src_qt3support_dialogs_q3filedialog.cpp 4
|
---|
2149 |
|
---|
2150 | The last important function you will need to use when creating your
|
---|
2151 | own file dialog is selectedFile().
|
---|
2152 |
|
---|
2153 | \snippet doc/src/snippets/code/src_qt3support_dialogs_q3filedialog.cpp 5
|
---|
2154 |
|
---|
2155 | In the above example, a modal file dialog is created and shown. If
|
---|
2156 | the user clicked OK, then the file they selected is put in \c
|
---|
2157 | fileName.
|
---|
2158 |
|
---|
2159 | If you are using the \l ExistingFiles mode then you will need to use
|
---|
2160 | selectedFiles() which will return the selected files in a QStringList.
|
---|
2161 |
|
---|
2162 | The dialog's working directory can be set with setDir(). The display
|
---|
2163 | of hidden files is controlled with setShowHiddenFiles(). The dialog
|
---|
2164 | can be forced to re-read the directory with rereadDir() and re-sort
|
---|
2165 | the directory with resortDir(). All the files in the current directory
|
---|
2166 | can be selected with selectAll().
|
---|
2167 |
|
---|
2168 | \section1 Creating and using preview widgets
|
---|
2169 |
|
---|
2170 | There are two kinds of preview widgets that can be used with
|
---|
2171 | Q3FileDialogs: \e content preview widgets and \e information preview
|
---|
2172 | widgets. They are created and used in the same way except that the
|
---|
2173 | function names differ, e.g. setContentsPreview() and setInfoPreview().
|
---|
2174 |
|
---|
2175 | A preview widget is a widget that is placed inside a Q3FileDialog so
|
---|
2176 | that the user can see either the contents of the file, or information
|
---|
2177 | about the file.
|
---|
2178 |
|
---|
2179 | \snippet doc/src/snippets/code/src_qt3support_dialogs_q3filedialog.cpp 6
|
---|
2180 |
|
---|
2181 | In the above snippet, we create a preview widget which inherits from
|
---|
2182 | QLabel and Q3FilePreview. File preview widgets \e must inherit from
|
---|
2183 | Q3FilePreview.
|
---|
2184 |
|
---|
2185 | Inside the class we reimplement Q3FilePreview::previewUrl(), this is
|
---|
2186 | where we determine what happens when a file is selected. In the
|
---|
2187 | above example we only show a preview of the file if it is a valid
|
---|
2188 | pixmap. Here's how to make a file dialog use a preview widget:
|
---|
2189 |
|
---|
2190 | \snippet doc/src/snippets/code/src_qt3support_dialogs_q3filedialog.cpp 7
|
---|
2191 |
|
---|
2192 | The first line creates an instance of our preview widget. We then
|
---|
2193 | create our file dialog and call setContentsPreviewEnabled(true),
|
---|
2194 | this tell the file dialog to preview the contents of the currently
|
---|
2195 | selected file. We then call setContentsPreview() -- note that we pass
|
---|
2196 | the same preview widget twice. Finally, before showing the file
|
---|
2197 | dialog, we call setPreviewMode() setting the mode to \e Contents which
|
---|
2198 | will show the contents preview of the file that the user has selected.
|
---|
2199 |
|
---|
2200 | If you create another preview widget that is used for displaying
|
---|
2201 | information about a file, create it in the same way as the contents
|
---|
2202 | preview widget and call setInfoPreviewEnabled(), and
|
---|
2203 | setInfoPreview(). Then the user will be able to switch between the
|
---|
2204 | two preview modes.
|
---|
2205 |
|
---|
2206 | For more information about creating a Q3FilePreview widget see
|
---|
2207 | \l{Q3FilePreview}.

3285 | the file dialog will change to /var/tmp after entering /usr/tmp.

3286 | If \a resolveSymlinks is false, the file dialog will treat

|

3376 | selected by the user. The file does not have to exist.
|
---|
3377 |
|
---|
3378 | It creates a modal file dialog called \a name, with parent, \a parent.
|
---|
3379 | If a parent is not 0, the dialog will be shown centered over the
|
---|
3380 | parent.

|
---|
3383 |
|
---|
3384 | The file dialog's working directory will be set to \a startWith. If \a
|
---|
3385 | startWith includes a file name, the file will be selected. The filter
|
---|
3386 | is set to \a filter so that only those files which match the filter
|
---|
3387 | are shown. The filter selected is set to \a selectedFilter. The parameters
|
---|
3388 | \a startWith, \a selectedFilter and \a filter may be an empty string.
|
---|
3389 |
|
---|
3390 | The dialog's caption is set to \a caption. If \a caption is not
|
---|
3391 | specified then a default caption will be used.
|
---|
3392 |
|
---|
3393 | Under Windows and Mac OS X, this static function will use the native
|
---|
3394 | file dialog and not a Q3FileDialog, unless the style of the application
|
---|
3395 | is set to something other than the native style. (Note that on Windows the
|
---|
3396 | dialog will spin a blocking modal event loop that will not dispatch any
|
---|
3397 | QTimers and if parent is not 0 then it will position the dialog just under
|
---|
3398 | the parent's title bar. And on the Mac the filter argument is ignored).
|
---|
3399 |
|
---|
3400 | Under Unix/X11, the normal behavior of the file dialog is to resolve
|
---|
3401 | and follow symlinks. For example, if /usr/tmp is a symlink to /var/tmp,
|
---|
3402 | the file dialog will change to /var/tmp after entering /usr/tmp.
|
---|
3403 | If \a resolveSymlinks is false, the file dialog will treat
|
---|
3404 | symlinks as regular directories.

4286 |
|

4287 | This function creates a modal file dialog called \a name, with
|
---|
4288 | parent, \a parent. If parent is not 0, the dialog will be shown
|
---|
4289 | centered over the parent.
|
---|
4290 |
|
---|
4291 | The dialog's working directory is set to \a dir, and the caption is
|
---|
4292 | set to \a caption. Either of these may be an empty string in which case
|
---|
4293 | the current directory and a default caption will be used respectively.
|
---|
4294 |
|
---|
4295 | If \a dirOnly is true, then only directories will be shown in
|
---|
4296 | the file dialog; otherwise both directories and files will be shown.
|
---|
4297 |
|
---|
4298 | Under Unix/X11, the normal behavior of the file dialog is to resolve
|
---|
4299 | and follow symlinks. For example, if /usr/tmp is a symlink to /var/tmp,
|
---|
4300 | the file dialog will change to /var/tmp after entering /usr/tmp.
|
---|
4301 | If \a resolveSymlinks is false, the file dialog will treat
|
---|
4302 | symlinks as regular directories.
|
---|
4303 |
|
---|
4304 | Note that on Windows the dialog will spin a blocking modal event loop
|
---|
4305 | that will not dispatch any QTimers and if parent is not 0 then it will
|
---|
4306 | position the dialog just under the parent's title bar.

5270 | This function creates a modal file dialog called \a name, with
|
---|
5271 | parent \a parent. If \a parent is not 0, the dialog will be shown
|
---|
5272 | centered over the parent.
|
---|
5273 |
|
---|
5274 | The file dialog's working directory will be set to \a dir. If \a
|
---|
5275 | dir includes a file name, the file will be selected. The filter
|
---|
5276 | is set to \a filter so that only those files which match the filter
|
---|
5277 | are shown. The filter selected is set to \a selectedFilter. The parameters
|
---|
5278 | \a dir, \a selectedFilter and \a filter may be empty strings.
|
---|
5279 |
|
---|
5280 | The dialog's caption is set to \a caption. If \a caption is not
|
---|
5281 | specified then a default caption will be used.
|
---|
5282 |
|
---|
5283 | Under Windows and Mac OS X, this static function will use the native
|
---|
5284 | file dialog and not a Q3FileDialog, unless the style of the application
|
---|
5285 | is set to something other than the native style. (Note that on Windows the
|
---|
5286 | dialog will spin a blocking modal event loop that will not dispatch any
|
---|
5287 | QTimers and if parent is not 0 then it will position the dialog just under
|
---|
5288 | the parent's title bar).
|
---|
5289 |
|
---|
5290 | Under Unix/X11, the normal behavior of the file dialog is to resolve
|
---|
5291 | and follow symlinks. For example, if /usr/tmp is a symlink to /var/tmp,
|
---|
5292 | the file dialog will change to /var/tmp after entering /usr/tmp.
|
---|
5293 | If \a resolveSymlinks is false, the file dialog will treat
|
---|
5294 | symlinks as regular directories.
|
---|
5295 |
|
---|
5296 | Note that if you want to iterate over the list of files, you should
|
---|
5297 | iterate over a copy, e.g.

6025 |
|
---|
6026 | This class is an abstract base class which is used to implement
|
---|
6027 | widgets that can display a preview of a file in a Q3FileDialog.
|
---|
6028 |
|
---|
6029 | You must derive the preview widget from both QWidget and from this
|
---|
6030 | class. Then you must reimplement this class's previewUrl() function,
|
---|
6031 | which is called by the file dialog if the preview of a file
|
---|
6032 | (specified as a URL) should be shown.

---|
