Provide a user (and developer) friendly way to select files and directories.
The widget can be used as a drop in replacement for the QFileDialog widget, but has greater functionality and a nicer GUI.
You will usually want to use one of the static methods getOpenFileName(), getSaveFileName(), getOpenURL() or for multiple files getOpenFileNames() or getOpenURLs().
The dialog has been designed to allow applications to customise it by subclassing. It uses geometry management to ensure that subclasses can easily add children that will be incorporated into the layout.
| KFileDialog (const QString& urlName, const QString& filter, QWidget *parent, const char *name, bool modal)
| KFileDialog |
Construct a file dialog.
Parameters:
| urlName | The URL of the directory to start in. Use QString::null to start in the current working directory, or the last directory where a file has been selected. |
| filter | A shell glob that specifies which files to display. See setFilter() for details on how to use this argument. |
| acceptURLs | If set to false, KFileDialog will
just accept files on the local filesystem.
|
| ~KFileDialog ()
| ~KFileDialog |
Destruct the file dialog.
| KURL selectedURL ()
| selectedURL |
[const]
Returns: The selected fully qualified filename.
| KURL::List selectedURLs ()
| selectedURLs |
[const]
Returns: The list of selected URLs.
| KURL baseURL ()
| baseURL |
[const]
Returns: the currently shown directory.
| QString selectedFile ()
| selectedFile |
[const]
Retrieve the full path of the selected file in the local filesystem. (Local files only)
| QStringList selectedFiles ()
| selectedFiles |
[const]
Retrieve a list of all selected local files.
| void setURL (const KURL &url, bool clearforward = true)
| setURL |
Set the directory to view.
Parameters:
| url | URL to show. |
| clearforward | Indicates whether the forward queue should be cleared. |
| void setSelection (const QString& name)
| setSelection |
Set the file name to preselect to name
This takes absolute URLs and relative file names.
| void setKeepLocation ( bool keep )
| setKeepLocation |
Sets whether the filename/url should be kept when changing directories. This is for example useful when having a predefined filename where the full path for that file is searched.
getSaveFileName() and getSaveURL() set this to true by default, so that you can type in the filename and change the directory without having to type the name again.
| bool keepsLocation ()
| keepsLocation |
[const]
Returns: whether the contents of the location edit are kept when changing directories.
| void setFilter (const QString& filter)
| setFilter |
Set the filter to be used to filter.
You can set more filters for the user to select seperated by '\n'. Every filter entry is defined through namefilter|text to diplay. If no | is found in the expression, just the namefilter is shown. Examples:
kfile->setFilter("*.cpp|C++ Source Files\n*.h|Header files"); kfile->setFilter("*.cpp"); kfile->setFilter("*.cpp|Sources (*.cpp)"); kfile->setFilter("*.cpp *.cc *.C|C++ Source Files\n*.h *.H|Header files"); |
Note: The text to display is not parsed in any way. So, if you want to show the suffix to select by a specific filter, you must repeat it.
See also: filterChanged()
| QString currentFilter ()
| currentFilter |
[const]
Retrieve the current filter as entered by the user or one of the predefined set via setFilter().
Parameters:
| filter | Contains the new filter (only the extension part, not the explanation), for example, "*.cpp" or "*.cpp *.cc". |
See also: setFilter(), filterChanged()
| void setFilterMimeType (const QString &label, const KMimeType::List &types, const KMimeType::Ptr &defaultType)
| setFilterMimeType |
Set the filter up to specify the output type.
Do not use in conjunction with setFilter()
Parameters:
| label | the label to use instead of "Filter:" |
| types | a list of mimetypes that can be used as output format |
| defaultType | the default mimetype to use as output format. |
| KMimeType::Ptr currentFilterMimeType ()
| currentFilterMimeType |
The mimetype for the desired output format.
This is only valid if setFilterMimeType() has been called previously.
See also: setFilterMimeType()
| void setPreviewWidget (const QWidget *w)
| setPreviewWidget |
Add a preview widget and enter the preview mode.
In this mode the dialog is split and the right part contains your widget. This widget has to inherit QWidget and it has to implement a slot showPreview(const KURL &); which is called every time the file changes. You may want to look at koffice/lib/kofficecore/koFilterManager.cc for some hints :)

[virtual]
| void setMode ( KFile::Mode m )
| setMode |
Set the mode of the dialog.
The mode is defined as (in kfile.h):
enum Mode {
File = 1,
Directory = 2,
Files = 4,
ExistingOnly = 8,
LocalOnly = 16
};
|
You can OR the values, e.g.
KFile::Mode mode = static_cast<KFile::Mode>( KFile::Files | KFile::ExistingOnly | KFile::LocalOnly ); setMode( mode ); |
You need an explicit cast, which looks a little ugly, but is unavoidable without using (even uglier) #defines.
| KFile::Mode mode ()
| mode |
[const]
Retrieve the mode of the filedialog.
See also: setMode()
| void setLocationLabel (const QString& text)
| setLocationLabel |
Set the text to be displayed in front of the selection.
The default is "Location". Most useful if you want to make clear what the location is used for.
| KToolBar * toolBar ()
| toolBar |
[const]
Retrieve a pointer to the toolbar.
You can use this to insert custom items into it, e.g.:
yourAction = new KAction( i18n("Your Action"), 0,
this, SLOT( yourSlot() ),
this, "action name" );
yourAction->plug( kfileDialog->toolBar() );
|
| QPushButton * okButton ()
| okButton |
[const]
Returns: a pointer to the OK-Button in the filedialog. You may use it e.g. to set a custom text to it.
| QPushButton * cancelButton ()
| cancelButton |
[const]
Returns: a pointer to the Cancel-Button in the filedialog. You may use it e.g. to set a custom text to it.
| void fileSelected (const QString&)
| fileSelected |
[signal]
Emitted when the user selects a file. It is only emitted in single- selection mode. The best way to get notified about selected file(s) is to connect to the okClicked() signal inherited from KDialogBase and call selectedFile(), selectedFiles(), selectedURL() or selectedURLs().
| void fileHighlighted (const QString&)
| fileHighlighted |
[signal]
Emitted when the user highlights a file.
| void selectionChanged ()
| selectionChanged |
[signal]
Emitted when the user hilights one or more files in multiselection mode.
Note: fileHighlighted() or fileSelected() are not emitted in multiselection mode. You may use selectedItems() to ask for the current highlighted items.
See also: fileSelected
| void filterChanged ( const QString& filter )
| filterChanged |
[signal]
Emitted when the filter changed, i.e. the user entered an own filter or chose one of the predefined set via setFilter().
