class (BoxedPtr o, TypedObject o, IsDescendantOf CairoNode o) => IsCairoNode o Source #

Type class for types which can be safely cast to CairoNode, for instance with toCairoNode.

toCairoNode :: (MonadIO m, IsCairoNode o) => o -> m CairoNode Source #

Cast to CairoNode, for types for which this is known to be safe. For general casts, use castTo.

Methods

Overloaded methods

getDrawContext

cairoNodeGetDrawContext Source #

Arguments

:: (HasCallStack, MonadIO m, IsCairoNode a)
=> a	`node`: a `RenderNode` for a Cairo surface
-> m Context	Returns: a Cairo context used for drawing; use `cairo_destroy()` when done drawing

Creates a Cairo context for drawing using the surface associated to the render node.

If no surface exists yet, a surface will be created optimized for rendering to renderer.

new

cairoNodeNew Source #

Arguments

:: (HasCallStack, MonadIO m)
=> Rect	`bounds`: the rectangle to render to
-> m CairoNode	Returns: A new `RenderNode`

Creates a RenderNode that will render a cairo surface into the area given by bounds. You can draw to the cairo surface using cairoNodeGetDrawContext

peekSurface

cairoNodePeekSurface Source #

Arguments

:: (HasCallStack, MonadIO m, IsCairoNode a)
=> a	`node`: a `RenderNode` for a Cairo surface
-> m Surface	Returns: a Cairo surface

Retrieves the Cairo surface used by the render node.
