/// [`DrawingArea`][crate::DrawingArea] is a widget that allows drawing with cairo.
///
/// 
///
/// It’s essentially a blank widget; you can draw on it. After
/// creating a drawing area, the application may want to connect to:
///
/// - The [`realize`][struct@crate::Widget#realize] signal to take any necessary actions
/// when the widget is instantiated on a particular display.
/// (Create GDK resources in response to this signal.)
///
/// - The [`resize`][struct@crate::DrawingArea#resize] signal to take any necessary
/// actions when the widget changes size.
///
/// - Call [`DrawingAreaExtManual::set_draw_func()`][crate::prelude::DrawingAreaExtManual::set_draw_func()] to handle redrawing the
/// contents of the widget.
///
/// The following code portion demonstrates using a drawing
/// area to display a circle in the normal widget foreground
/// color.
///
/// ## Simple GtkDrawingArea usage
///
/// **⚠️ The following code is in c ⚠️**
///
/// ```c
/// static void
/// draw_function (GtkDrawingArea *area,
/// cairo_t *cr,
/// int width,
/// int height,
/// gpointer data)
/// {
/// GdkRGBA color;
///
/// cairo_arc (cr,
/// width / 2.0, height / 2.0,
/// MIN (width, height) / 2.0,
/// 0, 2 * G_PI);
///
/// gtk_widget_get_color (GTK_WIDGET (area),
/// &color);
/// gdk_cairo_set_source_rgba (cr, &color);
///
/// cairo_fill (cr);
/// }
///
/// int
/// main (int argc, char **argv)
/// {
/// gtk_init ();
///
/// GtkWidget *area = gtk_drawing_area_new ();
/// gtk_drawing_area_set_content_width (GTK_DRAWING_AREA (area), 100);
/// gtk_drawing_area_set_content_height (GTK_DRAWING_AREA (area), 100);
/// gtk_drawing_area_set_draw_func (GTK_DRAWING_AREA (area),
/// draw_function,
/// NULL, NULL);
/// return 0;
/// }
/// ```
///
/// The draw function is normally called when a drawing area first comes
/// onscreen, or when it’s covered by another window and then uncovered.
/// You can also force a redraw by adding to the “damage region” of the
/// drawing area’s window using [`WidgetExt::queue_draw()`][crate::prelude::WidgetExt::queue_draw()].
/// This will cause the drawing area to call the draw function again.
///
/// The available routines for drawing are documented in the
/// [Cairo documentation](https://www.cairographics.org/manual/); GDK
/// offers additional API to integrate with Cairo, like `cairo_set_source_rgba()`
/// or `cairo_set_source_pixbuf()`.
///
/// To receive mouse events on a drawing area, you will need to use
/// event controllers. To receive keyboard events, you will need to set
/// the “can-focus” property on the drawing area, and you should probably
/// draw some user-visible indication that the drawing area is focused.
///
/// If you need more complex control over your widget, you should consider
/// creating your own [`Widget`][crate::Widget] subclass.

/// and <kbd>Shift</kbd>+<kbd>Tab</kbd> to move backward.
///
/// Action
///
///
/// #### `query-tooltip`
/// Emitted when the widget’s tooltip is about to be shown.
///
/// This happens when the [`has-tooltip`][struct@crate::Widget#has-tooltip] property
/// is [`true`] and the hover timeout has expired with the cursor hovering
/// "above" @widget; or emitted when @widget got focus in keyboard mode.
///
/// Using the given coordinates, the signal handler should determine
/// whether a tooltip should be shown for @widget. If this is the case
/// [`true`] should be returned, [`false`] otherwise. Note that if
/// @keyboard_mode is [`true`], the values of @x and @y are undefined and
/// should not be used.
///
/// The signal handler is free to manipulate @tooltip with the therefore
/// destined function calls.
///
///
///
///
/// #### `realize`
/// Emitted when @widget is associated with a [`gdk::Surface`][crate::gdk::Surface].
///
/// This means that [`WidgetExt::realize()`][crate::prelude::WidgetExt::realize()] has been called
/// or the widget has been mapped (that is, it is going to be drawn).
///
///
///
///
/// #### `show`
/// Emitted when @widget is shown.
///
///
///
///
/// #### `state-flags-changed`
/// Emitted when the widget state changes.
///
/// See [`WidgetExt::state_flags()`][crate::prelude::WidgetExt::state_flags()].
///
///
///
///
/// #### `unmap`
/// Emitted when @widget is going to be unmapped.
///
/// A widget is unmapped when either it or any of its parents up to the
/// toplevel widget have been set as hidden.
///
/// As ::unmap indicates that a widget will not be shown any longer,
/// it can be used to, for example, stop an animation on the widget.
///
///
///
///
/// #### `unrealize`
/// Emitted when the [`gdk::Surface`][crate::gdk::Surface] associated with @widget is destroyed.
///
/// This means that [`WidgetExt::unrealize()`][crate::prelude::WidgetExt::unrealize()] has been called
/// or the widget has been unmapped (that is, it is going to be hidden).
