Detailed Description

Base class for KFileWidget.

This abstract interface allows KFileDialog (in kio) to call methods on the dlopened KFileWidget (from kfilemodule.so)

In addition to the pure virtual methods defined below, the implementations of KAbstractFileWidget are expected to define the following signals:

fileSelected(const KUrl&)
fileHighlighted(const KUrl&)
selectionChanged()
filterChanged(const QString&)
accepted()

Definition at line 57 of file kabstractfilewidget.h.

Member Enumeration Documentation

enum KAbstractFileWidget::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.

pure virtual

Clears any mime- or namefilter.

Does not reload the directory.

virtual QString KAbstractFileWidget::currentFilter ( ) const

pure virtual

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

See also: setFilter(); filterChanged()

virtual KMimeType::Ptr KAbstractFileWidget::currentFilterMimeType ( )

pure virtual

Returns the mimetype for the desired output format.

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

See also: setFilterMimeType()

virtual QString KAbstractFileWidget::currentMimeFilter ( ) const

pure virtual

The mimetype for the desired output format.

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

See also: setMimeFilter()

pure virtual

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

virtual KFile::Modes KAbstractFileWidget::mode ( ) const

pure virtual

Returns the mode of the filedialog.

See also: setMode()

virtual KPushButton* KAbstractFileWidget::okButton ( ) const

pure virtual

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.

virtual OperationMode KAbstractFileWidget::operationMode ( ) const

pure virtual

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

See also: operationMode; KFileDialog::OperationMode

virtual QString KAbstractFileWidget::selectedFile ( ) const

pure virtual

Returns the full path of the selected file in the local filesystem.

(Local files only)

virtual QStringList KAbstractFileWidget::selectedFiles ( ) const

pure virtual

Returns a list of all selected local files.

virtual KUrl KAbstractFileWidget::selectedUrl ( ) const

pure virtual

Returns: The selected fully qualified filename.

virtual KUrl::List KAbstractFileWidget::selectedUrls ( ) const

pure virtual

Returns: The list of selected URLs.

void KAbstractFileWidget::setConfirmOverwrite ( bool enable )

inline

Sets whether the user should be asked for confirmation when an overwrite might occurr.

Parameters

enable Set this to true to enable checking.

Since: 4.2

Definition at line 383 of file kabstractfilewidget.h.

virtual void KAbstractFileWidget::setCustomWidget ( QWidget * widget )

pure virtual

Set a custom widget that should be added to the bottom of the file dialog.

Parameters

widget A widget, or a widget of widgets, for displaying custom data in the file widget. This can be used, for example, to display a check box with the caption "Open as read-only". When creating this widget, you don't need to specify a parent, since the widget's parent will be set automatically by KFileWidget.

virtual void KAbstractFileWidget::setCustomWidget	(	const QString &	text,
		QWidget *	widget
	)

pure virtual

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.

virtual void KAbstractFileWidget::setFilter ( const QString & filter )

pure virtual

Sets the filter to be used to filter.

You can set more filters for the user to select separated by '
'. 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; setMimeFilter

void KAbstractFileWidget::setInlinePreviewShown ( bool show )

inline

Forces the inline previews to be shown or hidden, depending on show.

Parameters

show	Whether to show inline previews or not.

Since: 4.2

Definition at line 393 of file kabstractfilewidget.h.

virtual void KAbstractFileWidget::setKeepLocation ( bool keep )

pure virtual

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.

virtual void KAbstractFileWidget::setLocationLabel ( const QString & text )

pure virtual

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.

virtual void KAbstractFileWidget::setMimeFilter	(	const QStringList &	types,
		const QString &	defaultType = `QString()`
	)

pure virtual

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()

virtual void KAbstractFileWidget::setMode ( KFile::Modes m )

pure virtual

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 );

virtual void KAbstractFileWidget::setOperationMode ( OperationMode )

pure virtual

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 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 KFileDialog.

See also: operationMode; KFileDialog::OperationMode

virtual void KAbstractFileWidget::setPreviewWidget ( KPreviewWidgetBase * w )

pure virtual

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 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.

virtual void KAbstractFileWidget::setSelection ( const QString & name )

pure virtual

Sets the file name to preselect to name.

This takes absolute URLs and relative file names.

virtual void KAbstractFileWidget::setUrl	(	const KUrl &	url,
		bool	clearforward = `true`
	)

pure virtual

Sets the directory to view.

Parameters

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

virtual void KAbstractFileWidget::slotCancel ( )

pure virtual

virtual void KAbstractFileWidget::slotOk ( )

pure virtual

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

virtual KToolBar* KAbstractFileWidget::toolBar ( ) const

pure virtual

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() );

virtual void KAbstractFileWidget::virtual_hook	(	int	id,
		void *	data
	)

pure virtual
