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.
enum OperationMode { Other = 0, Opening, Saving } | OperationMode |
Defines some default behavior of the filedialog.
E.g. in mode Opening
and Saving
, the selected files/urls will
be added to the "recent documents" list. The Saving mode also implies
setKeepLocation() being set.
Other
means that no default actions are performed.

KFileDialog (const QString& startDir, const QString& filter,
QWidget *parent, const char *name,
bool modal)
| KFileDialog |
Construct a file dialog.
Parameters:
startDir | This can either be |
filter | A shell glob or a mime-type-filter 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 setOperationMode ( KFileDialog::OperationMode )
| setOperationMode |
Sets the operational mode of the filedialog to Saving
, Opening
or Other
. This will set some flags that are specific to loading
or saving files. E.g. setKeepLocation() makes mostly sense for
a save-as dialog. So setOperationMode( KFileDialog::Saving ); sets
setKeepLocation for example.
The default mode is Other
.
Call this method right after instantiating KFileDialog.
See also: operationMode, OperationMode
OperationMode operationMode ()
| operationMode |
[const]
Returns: the current operation mode, Opening, Saving or Other. Default is Other.
See also: operationMode, OperationMode
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.
This is implicitly set when operationMode() is KFileDialog::Saving
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.
If the filter contains a '/', a mimetype-filter is assumed. You can specify multiple mimetypes like this (separated with space):
kfile->setFilter( "image/png text/html text/plain" ); |
See also: filterChanged, setMimeFilter
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 |

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 |

This is only valid if setFilterMimeType() has been called previously.
See also: setFilterMimeType()
void setMimeFilter ( const QStringList& types,
const QString& defaultType = QString::null )
| setMimeFilter |
Set the filter up to specify the output type.
Do not use in conjunction with setFilter()
Parameters:
types | a list of mimetypes that can be used as output format |
defaultType | the default mimetype to use as output format, if any.
If defaultType is set, it will be set as the current item.
Otherwise, a first item showing all the mimetypes will be created.
Typically, defaultType should be empty for loading and set for saving.
|
QString currentMimeFilter ()
| currentMimeFilter |
[const]
The mimetype for the desired output format.
This is only valid if setMimeFilter() has been called previously.
See also: setMimeFilter()
void clearFilter ()
| clearFilter |
Clears any mime- or namefilter. Does not reload the directory.
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 :)
Ownership is transferred to KFileDialog. You need to create the preview-widget with "new", i.e. on the heap.
void setPreviewWidget (const KPreviewWidgetBase *w)
| setPreviewWidget |
Add a preview widget and enter the preview mode.
In this mode the dialog is split and the right part contains your preview widget.
Ownership is transferred to KFileDialog. You need to create the preview-widget with "new", i.e. on the heap.
Parameters:
w | The widget to be used for the preview. |
