Struct gtk4::FileChooser[][src]

pub struct FileChooser(_);
Expand description

FileChooser is an interface that can be implemented by file selection widgets.

In GTK, the main objects that implement this interface are FileChooserWidget and FileChooserDialog.

You do not need to write an object that implements the FileChooser interface unless you are trying to adapt an existing file selector to expose a standard programming interface.

FileChooser allows for shortcuts to various places in the filesystem. In the default implementation these are displayed in the left pane. It may be a bit confusing at first that these shortcuts come from various sources and in various flavours, so lets explain the terminology here:

  • Bookmarks: are created by the user, by dragging folders from the right pane to the left pane, or by using the “Add”. Bookmarks can be renamed and deleted by the user.

  • Shortcuts: can be provided by the application. For example, a Paint program may want to add a shortcut for a Clipart folder. Shortcuts cannot be modified by the user.

  • Volumes: are provided by the underlying filesystem abstraction. They are the “roots” of the filesystem.

File Names and Encodings

When the user is finished selecting files in a FileChooser, your program can get the selected filenames as GFiles.

Adding options

You can add extra widgets to a file chooser to provide options that are not present in the default design, by using FileChooserExtManual::add_choice(). Each choice has an identifier and a user visible label; additionally, each choice can have multiple options. If a choice has no option, it will be rendered as a check button with the given label; if a choice has options, it will be rendered as a combo box.
