Signal Documentation

accepted ( )

Emitted by slotOk() (directly or asynchronously) once everything has been done. Should be used by the caller to call accept().

Signal syntax:: QObject.connect(source, SIGNAL("accepted()"), target_slot)

fileHighlighted	(	QString	a0
	)

@deprecated, connect to fileSelected(const KUrl&) instead

Signal syntax:: QObject.connect(source, SIGNAL("fileHighlighted(const QString&)"), target_slot)

fileHighlighted	(	KUrl	a0
	)

@deprecated, connect to fileSelected(const KUrl&) instead

Signal syntax:: QObject.connect(source, SIGNAL("fileHighlighted(const KUrl&)"), target_slot)

fileSelected	(	QString	a0
	)

@deprecated, connect to fileSelected(const KUrl&) instead

Signal syntax:: QObject.connect(source, SIGNAL("fileSelected(const QString&)"), target_slot)

fileSelected	(	KUrl	a0
	)

@deprecated, connect to fileSelected(const KUrl&) instead

Signal syntax:: QObject.connect(source, SIGNAL("fileSelected(const KUrl&)"), target_slot)

filterChanged	(	QString	filter
	)

Emitted when the filter changed, i.e. the user entered an own filter or chose one of the predefined set via setFilter().

Parameters:

filter

contains the new filter (only the extension part, not the explanation), i.e. "*.cpp" or "*.cpp *.cc".

See also:: currentFilter()

Signal syntax:: QObject.connect(source, SIGNAL("filterChanged(const QString&)"), target_slot)

selectionChanged ( )

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.

Signal syntax:: QObject.connect(source, SIGNAL("selectionChanged()"), target_slot)

Method Documentation

__init__	(	self,
		KUrl	startDir,
		QWidget	parent
	)

Constructs a file selector widget.

Parameters:

startDir

This can either be:

An empty URL (KUrl()) to start in the current working directory,

or the last directory where a file has been selected.

The path or URL of a starting directory.

An initial file name to select, with the starting directory being

the current working directory or the last directory where a file has been selected.

The path or URL of a file, specifying both the starting directory and

an initially selected file name.

A URL of the form kfiledialog:<keyword> to start in the

directory last used by a filedialog in the same application that specified the same keyword.

A URL of the form kfiledialog:<keyword>/<filename>

to start in the directory last used by a filedialog in the same application that specified the same keyword, and to initially select the specified filename.

A URL of the form kfiledialog:<keyword>?global to start

in the directory last used by a filedialog in any application that specified the same keyword.

A URL of the form kfiledialog:<keyword>/<filename>?global

to start in the directory last used by a filedialog in any application that specified the same keyword, and to initially select the specified filename.

Parameters:

parent

The parent widget of this widget

accept ( self )

KActionCollection actionCollection ( self )

Returns:: a pointer to the action collection, holding all the used KActions.

KUrl baseUrl ( self )

Returns:: the currently shown directory.

KPushButton cancelButton ( self )

Returns:: a pointer to the Cancel-Button in the filedialog. Note that the button is hidden and unconnected when using KFileWidget alone; KFileDialog shows it and connects to it.

clearFilter ( self )

Clears any mime- or namefilter. Does not reload the directory.

QString currentFilter ( self )

Returns the current filter as entered by the user or one of the predefined set via setFilter().

See also:: setFilter()

See also:: filterChanged()

KSharedPtr currentFilterMimeType ( self )

Returns the mimetype for the desired output format.

This is only valid if setFilterMimeType() has been called previously.

See also:: setFilterMimeType()

QString currentMimeFilter ( self )

The mimetype for the desired output format.

This is only valid if setMimeFilter() has been called previously.

See also:: setMimeFilter()

KDirOperator dirOperator ( self )

Returns:: the KDirOperator used to navigate the filesystem

Since:: 4.3

bool eventFilter	(	self,
		QObject	watched,
		QEvent	event
	)

KFileFilterCombo filterWidget ( self )

Returns:: the combobox that contains the filters

bool keepsLocation ( self )

Returns:: whether the contents of the location edit are kept when changing directories.

KUrlComboBox locationEdit ( self )

Returns:: the combobox used to type the filename or full location of the file.

KFile.Modes mode ( self )

Returns the mode of the filedialog.

See also:: setMode()

KPushButton okButton ( self )

Returns:: a pointer to the OK-Button in the filedialog. Note that the button is hidden and unconnected when using KFileWidget alone; KFileDialog shows it and connects to it.

KAbstractFileWidget.OperationMode operationMode ( self )

Returns:: the current operation mode, Opening, Saving or Other. Default is Other.

See also:: operationMode

See also:: KFileWidget.OperationMode

readConfig	(	self,
		KConfigGroup	group
	)

reads the configuration for this widget from the given config group

Parameters:

group

the KConfiGroup to read from

Since:: 4.4

resizeEvent	(	self,
		QResizeEvent	event
	)

QString selectedFile ( self )

Returns the full path of the selected file in the local filesystem. (Local files only)

QStringList selectedFiles ( self )

Returns a list of all selected local files.

KUrl selectedUrl ( self )

Returns:: The selected fully qualified filename.

KUrl.List selectedUrls ( self )

Returns:: The list of selected URLs.

setCustomWidget	(	self,
		QWidget	widget
	)

Sets a custom widget that should be added below the location and the filter editors.

Parameters:

	text	Label of the custom widget, which is displayed below the labels "Location:" and "Filter:".
	widget	Any kind of widget, but preferable a combo box or a line editor to be compliant with the location and filter layout. When creating this widget, you don't need to specify a parent, since the widget's parent will be set automatically by KFileWidget.

setCustomWidget	(	self,
		QString	text,
		QWidget	widget
	)

Sets a custom widget that should be added below the location and the filter editors.

Parameters:

	text	Label of the custom widget, which is displayed below the labels "Location:" and "Filter:".
	widget	Any kind of widget, but preferable a combo box or a line editor to be compliant with the location and filter layout. When creating this widget, you don't need to specify a parent, since the widget's parent will be set automatically by KFileWidget.

setFilter	(	self,
		QString	filter
	)

Sets the filter to be used to filter.

You can set more filters for the user to select separated by '\n'. Every filter entry is defined through namefilter|text to display. 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|" + i18n("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 an unescaped '/', a mimetype-filter is assumed. If you would like a '/' visible in your filter it can be escaped with a '\'. You can specify multiple mimetypes like this (separated with space):

 kfile->setFilter( "image/png text/html text/plain" );
 kfile->setFilter( "*.cue|CUE\\/BIN Files (*.cue)" );

See also:: filterChanged

See also:: setMimeFilter

setKeepLocation	(	self,
		bool	keep
	)

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 KFileWidget.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.

setLocationLabel	(	self,
		QString	text
	)

Sets 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.

setMimeFilter	(	self,
		QStringList	types,
		QString	defaultType=QString()
	)

Sets the filter up to specify the output type.

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.

Do not use in conjunction with setFilter()

setMode	(	self,
		KFile.Modes	m
	)

Sets 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.Modes mode = KFile.Files |
                     KFile.ExistingOnly |
                     KFile.LocalOnly );
 setMode( mode );

setOperationMode	(	self,
		KAbstractFileWidget.OperationMode	a0
	)

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( KFileWidget.Saving ); sets setKeepLocation for example.

The mode Saving, together with a default filter set via setMimeFilter() will make the filter combobox read-only.

The default mode is Opening.

Call this method right after instantiating KFileWidget.

See also:: operationMode

See also:: KFileWidget.OperationMode

setPreviewWidget	(	self,
		KPreviewWidgetBase	w
	)

Adds a preview widget and enters the preview mode.

In this mode the dialog is split and the right part contains your preview widget.

Ownership is transferred to KFileWidget. You need to create the preview-widget with "new", i.e. on the heap.

Parameters:

The widget to be used for the preview.

setSelection	(	self,
		QString	name
	)

Sets the file name to preselect to name

This takes absolute URLs and relative file names.

setUrl	(	self,
		KUrl	url,
		bool	clearforward=1
	)

Sets the directory to view.

Parameters:

	url	URL to show.
	clearforward	Indicates whether the forward queue should be cleared.

showEvent	(	self,
		QShowEvent	event
	)

slotCancel ( self )

slotOk ( self )

Called when clicking ok (when this widget is used in KFileDialog) Might or might not call accept().

KToolBar toolBar ( self )

Returns 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() );

Static Method Documentation

KUrl getStartUrl	(	KUrl	startDir,
