Detailed Description

Provides a user (and developer) friendly way to select files and directories. A file selection dialog.

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.

Member Enumeration Documentation

enum KFileDialog::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.

Constructor & Destructor Documentation

KFileDialog::KFileDialog (  const QString &  startDir,
const QString &  filter,
QWidget *  parent,
const char *  name,
bool  modal
) 
 

Constructs a file dialog.

Parameters:
startDir This can either be
  • The URL of the directory to start in.
  • QString::null to start in the current working directory, or the last directory where a file has been selected.
  • ':<keyword>' to start in the directory last used by a filedialog in the same application that specified the same keyword.
  • '::<keyword>' to start in the directory last used by a filedialog in any application that specified the same keyword.
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.

Definition at line 165 of file kfiledialog.cpp.

References init().

KFileDialog::KFileDialog (  const QString &  startDir,
const QString &  filter,
QWidget *  parent,
const char *  name,
bool  modal,
QWidget *  widget
) 
 

Constructs a file dialog.

The parameters here are identical to the first constructor except for the addition of a QWidget parameter.

Historical note: The original version of KFileDialog did not have this extra parameter. It was added later, and, in order to maintain binary compatibility, it was placed in a new constructor instead of added to the original one.

Parameters:
startDir This can either be
  • The URL of the directory to start in.
  • QString::null to start in the current working directory, or the last directory where a file has been selected.
  • ':<keyword>' to start in the directory last used by a filedialog in the same application that specified the same keyword.
  • '::<keyword>' to start in the directory last used by a filedialog in any application that specified the same keyword.
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, the dialog will just accept files on the local filesystem.
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.

void KFileDialog::setOperationMode (  KFileDialog::OperationMode   ) 
 

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.

void KFileDialog::setKeepLocation (  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.

Definition at line 1730 of file kfiledialog.cpp.

bool KFileDialog::keepsLocation (   )  const
 

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

Definition at line 1735 of file kfiledialog.cpp.

void KFileDialog::setFilter (  const QString &  filter  ) 
 

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 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|" + 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)" );

Deprecated:
Add a preview widget and enter the preview mode.

You can OR the values, e.g. 
 KFile::Mode mode = static_cast<KFile::Mode>( KFile::Files |
                                              KFile::ExistingOnly |
                                              KFile::LocalOnly );
 setMode( mode );
