Struct gtk::FileChooserButton [−][src]
pub struct FileChooserButton(_);
Expand description
The FileChooserButton
is a widget that lets the user select a
file. It implements the FileChooser
interface. Visually, it is a
file name with a button to bring up a FileChooserDialog
.
The user can then use that dialog to change the file associated with
that button. This widget does not support setting the
property::FileChooser::select-multiple
property to true
.
Create a button to let the user select a file in /etc
⚠️ The following code is in C ⚠️
{
GtkWidget *button;
button = gtk_file_chooser_button_new (_("Select a file"),
GTK_FILE_CHOOSER_ACTION_OPEN);
gtk_file_chooser_set_current_folder (GTK_FILE_CHOOSER (button),
"/etc");
}
The FileChooserButton
supports the GtkFileChooserActions
FileChooserAction::Open
and FileChooserAction::SelectFolder
.
The
FileChooserButton
will ellipsize the label, and will thus request little horizontal space. To give the button more space, you should callWidgetExt::preferred_size()
,FileChooserButtonExt::set_width_chars()
, or pack the button in such a way that other interface elements give space to the widget.
CSS nodes
GtkFileChooserButton has a CSS node with name “filechooserbutton”, containing a subnode for the internal button with name “button” and style class “.file”.

Implementations
Creates a FileChooserButton
widget which uses dialog
as its
file-picking window.
Note that dialog
must be a Dialog
(or subclass) which
implements the FileChooser
interface and must not have
DialogFlags::DESTROY_WITH_PARENT
set.
Also note that the dialog needs to have its confirmative button
added with response ResponseType::Accept
or ResponseType::Ok
in
order for the button to take over the file selected in the dialog.

Returns
a new button widget.
Creates a new builder-pattern struct instance to construct FileChooserButton
objects.
This method returns an instance of FileChooserButtonBuilder
which can be used to create FileChooserButton
objects.
