Gtk.Widget.get_allocation

### Method

# Gtk Widgetget_allocation

#### Declaration [src]

    void
    gtk_widget_get_allocation (
      GtkWidget* widget,
      GtkAllocation* allocation
    )

#### Description [src]

Retrieves the widget’s allocation.

Note, when implementing a layout container: a widget’s allocation will be its “adjusted” allocation, that is, the widget’s parent typically calls `gtk_widget_size_allocate()` with an allocation, and that allocation is then adjusted (to handle margin and alignment for example) before assignment to the widget. `gtk_widget_get_allocation()` returns the adjusted allocation that was actually assigned to the widget. The adjusted allocation is guaranteed to be completely contained within the `gtk_widget_size_allocate()` allocation, however.

So a layout container is guaranteed that its children stay inside the assigned bounds, but not that they have exactly the bounds the container assigned.

#### Parameters

`allocation` | `GtkAllocation`
| A pointer to a `GtkAllocation` to copy to.
| The argument will be set by the function.
| The data is owned by the caller of the function.
