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.

|
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.

Sets the operational mode of the filedialog to 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

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.

Sets the filter to be used to
You can set more filters for the user to select separated by '
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)" );

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.
