Provide 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 customise it by subclassing. It uses geometry management to ensure that subclasses can easily add children that will be incorporated into the layout.
|
Construct a file dialog.
Parameters:
urlName | The URL of the directory to start in. Use QString::null to start in the current working directory, or the last directory where a file has been selected. |
filter | A shell glob that specifies which files to display. See setFilter() for details on how to use this argument. |
acceptURLs | If set to false, KFileDialog will
just accept files on the local filesystem.
|
~ |
Destruct the file dialog.
KURL |
[const]
Returns: The selected fully qualified filename.
KURL::List |
[const]
Returns: The list of selected URLs.
KURL |
[const]
Returns: the currently shown directory.
QString |
[const]
Retrieve the full path of the selected file in the local filesystem. (Local files only)
QStringList |
[const]
Retrieve a list of all selected local files.
void |
Set the directory to view.
Parameters:
url | URL to show. |
clearforward | Indicates whether the forward queue should be cleared. |
void |
Set the file name to preselect to name
This takes absolute URLs and relative file names.
void |
Set the filter to be used to filter.
You can set more filters for the user to select seperated by '\n'. 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 *.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.
QString |
[const]
Retrieve the current filter as entered by the user or one of the predefined set via setFilter().
WARNING: There is no parameter filter... so what is this doing here ?
Parameters:
filter | Contains the new filter (only the extension part, not the explanation), for example, "*.cpp" or "*.cpp *.cc". |
See also: setFilter(), filterChanged()
void |
Set the filter up to specify the output type.
Do not use in conjunction with setFilter()
Parameters:
label | the label to use instead of "Filter:" |
types | a list of mimetypes that can be used as output format |
defaultType | the default mimetype to use as output format. |
KMimeType::Ptr |
The mimetype for the desired output format.
This is only valid if setFilterMimeType() has been called previously.
void |
Add a preview widget and enter the preview mode.
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 :)
QString |
[static]
Create a modal file dialog and return the selected filename or an empty string if none was chosen.
Note that with this method the user must select an existing filename.

parent | The widget the dialog will be centered on initially. |
caption | The name of the dialog widget. |
QStringList |
[static]
Create a modal file dialog and return the selected filenames or an empty list if none was chosen.
Note that with this method the user must select an existing filename.
Parameters:
dir | This specifies the path the dialog will start in. |
filter | This is a space seperated list of shell globs. |
parent | The widget the dialog will be centered on initially. |
caption | The name of the dialog widget. |
KURL |
[static]
Create a modal file dialog and return the selected URL or an empty string if none was chosen.
Note that with this method the user must select an existing URL.
Parameters:
url | This specifies the path the dialog will start in. |
filter | This is a space seperated list of shell globs. |
parent | The widget the dialog will be centered on initially. |
caption | The name of the dialog widget. |
KURL::List |
[static]
Create a modal file dialog and return the selected URLs or an empty list if none was chosen.
Note that with this method the user must select an existing filename.
Parameters:
url | This specifies the path the dialog will start in. |
filter | This is a space seperated list of shell globs. |
parent | The widget the dialog will be centered on initially. |
caption | The name of the dialog widget. |
QString |
[static]
Create a modal file dialog and return the selected filename or an empty string if none was chosen.
Note that with this method the user need not select an existing filename.
Parameters:
dir | This specifies the path the dialog will start in. |
filter | This is a space seperated list of shell globs. |
parent | The widget the dialog will be centered on initially. |
caption | The name of the dialog widget. |
KURL |
[static]
Create a modal file dialog and returns the selected filename or an empty string if none was chosen.
Note that with this method the user need not select an existing filename.
Parameters:
url | This specifies the path the dialog will start in. |
filter | This is a space seperated list of shell globs. |
parent | The widget the dialog will be centered on initially. |
caption | The name of the dialog widget. |
QString |
[static]
Create a modal file dialog and returns the selected directory or an empty string if none was chosen.
Note that with this method the user need not select an existing directory.
Parameters:
url | The directory the dialog will start in. |
parent | The widget the dialog will be centered on initially. |
caption | The name of the dialog widget. |
void |
[virtual]
void |
Set 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::Mode mode = static_cast<KFile::Mode>( KFile::Files | KFile::ExistingOnly | KFile::LocalOnly ); setMode( mode );
You need an explicit cast, which looks a little ugly, but is unavoidable without using (even uglier) #defines. Please not that's at the moment not possible to select multiple files and directories <em>simultaneously</em>. It's possible to select one file or directory at once, though.
KFile::Mode |
[const]
Retrieve the mode of the filedialog.
void |
Set 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.
KToolBar * |
[const]
Retrieve 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() );
QPushButton * |
[const]
Returns: a pointer to the OK-Button in the filedialog. You may use it e.g. to set a custom text to it.
QPushButton * |
[const]
Returns: a pointer to the Cancel-Button in the filedialog. You may use it e.g. to set a custom text to it.
void |
[signal]
Emitted when the user selects a file.
void |
[signal]
Emitted when the user highlights a file.
void |
[signal]
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.
void |
[signal]
Emitted when the allowable history operations change.
void |
[signal]
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". |
