Detailed Description

template<typename DrawableType>
class roo_display::TileOf< DrawableType >

Tile with embedded interior object.

Useful when returning a tile without keeping a separate interior object.

Member Function Documentation

drawTo()

template<typename DrawableType >

void roo_display::TileOf< DrawableType >::drawTo ( const Surface &  s ) const

inlineoverridevirtual

Draw this object's content, respecting the fill mode.

If s.fill_mode() == FillMode::kExtents, the method must fill the entire (clipped) extents() rectangle (using s.bgcolor() for transparent parts).

The default implementation fills the clipped extents() rectangle with bgcolor and then calls drawInteriorTo(). That can cause flicker, so override this method if a better implementation is possible.

The implementation must respect surface parameters, particularly clip_box(), and must not draw outside it. The surface clip box is pre-clipped to fit within this drawable's extents().

Reimplemented from roo_display::Drawable.
