Expand description

Trait used to render each items.

The item needs to be rendered relative to its (x,y) position. For example, draw_rectangle should draw a rectangle in (pos.x + rect.x, pos.y + rect.y)

Required methods

source

fn draw_text(&mut self, text: Pin<&Text>)

source

fn draw_text_input(&mut self, text_input: Pin<&TextInput>)

Clip the further call until restore_state. radius/border_width can be used for border rectangle clip. (FIXME: consider removing radius/border_width and have another function that take a path instead)

Get the current clip bounding box in the current transformed coordinate.

Apply the opacity (between 0 and 1) for all following items until the next call to restore_state.

Returns the scale factor

Draw a pixmap in position indicated by the pos. The pixmap will be taken from cache if the cache is valid, otherwise, update_fn will be called with a callback that need to be called once with fn (width, height, data) where data are the RGBA premultiplied pixel values

Return the internal renderer
