* SECTION:gtkfilechooserbutton
|
||
* @Short_description: A button to launch a file chooser dialog
|
||
* @Title: GtkFileChooserButton
|
||
* @See_also:#GtkFileChooserDialog
|
||
*
|
||
* The #GtkFileChooserButton is a widget that lets the user select a
|
||
* file. It implements the #GtkFileChooser interface. Visually, it is a
|
||
* file name with a button to bring up a #GtkFileChooserDialog.
|
||
* The user can then use that dialog to change the file associated with
|
||
* that button. This widget does not support setting the
|
||
* #GtkFileChooser:select-multiple property to %TRUE.
|
||
*
|
||
* ## Create a button to let the user select a file in /etc
|
||
*
|
||
* |[<!-- language="C" -->
|
||
* {
|
||
* GtkWidget *button;
|
||
* GFile *cwd = g_file_new_for_path ("/etc");
|
||
*
|
||
* button = gtk_file_chooser_button_new (_("Select a file"),
|
||
* GTK_FILE_CHOOSER_ACTION_OPEN);
|
||
* gtk_file_chooser_set_current_folder (GTK_FILE_CHOOSER (button), cwd);
|
||
* g_object_unref (cwd);
|
||
* }
|
||
* ]|
|
||
*
|
||
* The #GtkFileChooserButton supports the #GtkFileChooserActions
|
||
* %GTK_FILE_CHOOSER_ACTION_OPEN and %GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER.
|
||
*
|
||
* > The #GtkFileChooserButton will ellipsize the label, and will thus
|
||
* > request little horizontal space. To give the button more space,
|
||
* > you should call gtk_widget_get_preferred_size(),
|
||
* > gtk_file_chooser_button_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 single CSS node with the name “filechooserbutton”.
