St.DrawingArea.get_context

### Method

# St DrawingAreaget_context

#### Declaration [src]

    cairo_t*
    st_drawing_area_get_context (
      StDrawingArea* area
    )

#### Description [src]

Gets the Cairo context to paint to. This function must only be called from a signal handler or virtual function for the `StDrawingArea::repaint` signal.

JavaScript code must call the special dispose function before returning from the signal handler or virtual function to avoid leaking memory:

    function onRepaint(area) {
        let cr = area.get_context();

        // Draw to the context

        cr.$dispose();
    }

    let area = new St.DrawingArea();
    area.connect('repaint', onRepaint);

#### Return value

Type: `cairo_t`

The Cairo context for the paint operation.

The returned data is owned by the instance.
