/// The `GtkButton` widget is generally used to trigger a callback function that is
/// called when the button is pressed.
/// 
/// ![An example GtkButton](button.png)
/// 
/// The `GtkButton` widget can hold any valid child widget. That is, it can hold
/// almost any other standard `GtkWidget`. The most commonly used child is the
/// `GtkLabel`.
/// 
/// # CSS nodes
/// 
/// `GtkButton` has a single CSS node with name button. The node will get the
/// style classes .image-button or .text-button, if the content is just an
/// image or label, respectively. It may also receive the .flat style class.
/// When activating a button via the keyboard, the button will temporarily
/// gain the .keyboard-activating style class.
/// 
/// Other style classes that are commonly used with `GtkButton` include
/// .suggested-action and .destructive-action. In special cases, buttons
/// can be made round by adding the .circular style class.
/// 
/// Button-like widgets like [class@Gtk.ToggleButton], [class@Gtk.MenuButton],
/// [class@Gtk.VolumeButton], [class@Gtk.LockButton], [class@Gtk.ColorButton]
/// or [class@Gtk.FontButton] use style classes such as .toggle, .popup, .scale,
/// .lock, .color on the button node to differentiate themselves from a plain
/// `GtkButton`.
/// 
/// # Accessibility
/// 
/// `GtkButton` uses the %GTK_ACCESSIBLE_ROLE_BUTTON role.
