Graphics.UI.Gtk.Selectors.FileSelection

FileSelection should be used to retrieve file or directory names from the user. It will create a new dialog window containing a directory list, and a file list corresponding to the current working directory. The filesystem can be navigated using the directory list or the drop-down history menu. Alternatively, the TAB key can be used to navigate using filename completion - common in text based editors such as emacs and jed.

File selection dialogs are created with a call to fileSelectionNew.

The default filename can be set using fileSelectionSetFilename and the selected filename retrieved using fileSelectionGetFilename.

Use fileSelectionComplete to display files and directories that match a given pattern. This can be used for example, to show only *.txt files, or only files beginning with gtk*.

Simple file operations; create directory, delete file, and rename file, are available from buttons at the top of the dialog. These can be hidden using fileSelectionHideFileopButtons and shown again using fileSelectionShowFileopButtons.

Constructors

fileSelectionNew

:: String	`title` - a message that will be placed in the file requestor's titlebar.
-> IO FileSelection
Creates a new file selection dialog box. By default it will contain a `TreeView` of the application's current working directory, and a file listing. Operation buttons that allow the user to create a directory, delete files and rename files, are also present.

Methods

fileSelectionSetFilename

:: FileSelectionClass self
=> self
-> String	`filename` - a string to set as the default file name.
-> IO ()
Sets a default path for the file requestor. If `filename` includes a directory path, then the requestor will open with that path as its current working directory. This has the consequence that in order to open the requestor with a working directory and an empty filename, `filename` must have a trailing directory separator.

fileSelectionGetFilename

:: FileSelectionClass self
=> self
-> IO String	returns currently-selected filename
This function returns the selected filename. If no file is selected then the selected directory path is returned.

fileSelectionShowFileopButtons :: FileSelectionClass self => self -> IO ()

Shows the file operation buttons, if they have previously been hidden. The rest of the widgets in the dialog will be resized accordingly.

fileSelectionHideFileopButtons :: FileSelectionClass self => self -> IO ()

Hides the file operation buttons that normally appear at the top of the dialog. Useful if you wish to create a custom file selector, based on FileSelection.

fileSelectionGetButtons :: FileSelectionClass fsel => fsel -> IO (Button, Button)

Extract the buttons of a fileselection.

fileSelectionComplete

:: FileSelectionClass self
=> self
-> String	`pattern` - a string of characters which may or may not match any filenames in the current directory.
-> IO ()
Will attempt to match `pattern` to a valid filenames or subdirectories in the current directory. If a match can be made, the matched filename will appear in the text entry field of the file selection dialog. If a partial match can be made, the "Files" list will contain those file names which have been partially matched, and the "Folders" list those directories which have been partially matched.

fileSelectionGetSelections :: FileSelectionClass self => self -> IO [String]

Retrieves the list of file selections the user has made in the dialog box. This function is intended for use when the user can select multiple files in the file list.

fileSelectionSetSelectMultiple

:: FileSelectionClass self
=> self
-> Bool	`selectMultiple` - whether or not the user is allowed to select multiple files in the file list.
-> IO ()
Sets whether the user is allowed to select multiple files in the file list. Use `fileSelectionGetSelections` to get the list of selected files.

fileSelectionGetSelectMultiple

:: FileSelectionClass self
=> self
-> IO Bool	returns `True` if the user is allowed to select multiple files in the file list
Determines whether or not the user is allowed to select multiple files in the file list. See `fileSelectionSetSelectMultiple`.
