KDE 4.5 PyKDE API Reference
KFileDialog Class Reference
from PyKDE4.kio import *
Inherits: KDialog → QDialog → QWidget → QObject
Subclasses: KEncodingFileDialog
Detailed Description
Provides 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 customize it by subclassing. It uses geometry management to ensure that subclasses can easily add children that will be incorporated into the layout.
"KDE File Dialog"
A file selection dialog.

Method Documentation
Constructs a file dialog.
- Parameters:
-
startDir Specifies the starting directory and/or initially selected file name, or a last used directory and optional file name using the kfiledialog: syntax. Refer to the KFileWidget documentation for more information on this parameter. filter A shell glob or a mime-type-filter that specifies which files to display. See setFilter() and setMimeFilter() for details on how to use this argument. parent The parent widget of this dialog widget A widget, or a widget of widgets, for displaying custom data in the dialog. 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 KFileDialog.

| KAbstractFileWidget fileWidget | ( | self ) |
Returns the KFileWidget that implements most of this file dialog. If you link to libkfile you can cast this to a KFileWidget*.
| KFileFilterCombo filterWidget | ( | self ) |
- Returns:
- the combobox that contains the filters You need to link to libkfile to use this widget.
| hideEvent | ( | self, | ||
| QHideEvent | event | |||
| ) |
Reimplemented for saving the dialog geometry.

| QKeyEvent | e | |||
| ) |

- the combobox used to type the filename or full location of the file. You need to link to libkfile to use this widget.
| 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. You may use it e.g. to set a custom text to it.
| KFileDialog.OperationMode operationMode | ( | self ) |
- Returns:
- the current operation mode, Opening, Saving or Other. Default is Other.
- See also:
- operationMode
- See also:
- KFileDialog.OperationMode
| 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.
| setConfirmOverwrite | ( | self, | ||
| bool | enable | |||
| ) |
Sets whether the dialog should ask before accepting the selected file when KFileDialog.OperationMode is set to Saving.
In this case a KMessageBox appears for confirmation.
- Parameters:
-
enable Set this to true to enable checking.
- Since:
- 4.2
| 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
| setInlinePreviewShown | ( | self, | ||
| bool | show | |||
| ) |
Forces the inline previews to be shown or hidden, depending on show.
- Parameters:
-
show Whether to show inline previews or not.
- Since:
- 4.2
| 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 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.
| 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, | ||
| KFileDialog.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( 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
- See also:
- KFileDialog.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 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.
| 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.
| QSize sizeHint | ( | self ) |
- See also:
- QWidget.sizeHint()
| slotCancel | ( | self ) |
| slotOk | ( | self ) |
| 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() );
