Overview

Note:

This class is untracked and should not be derived from nor instances extended!

MirrorDC is a simple wrapper class which is always associated with a real DC object and either forwards all of its operations to it without changes (no mirroring takes place) or exchanges x and y coordinates which makes it possible to reuse the same code to draw a figure and its mirror i.e.

reflection related to the diagonal line x == y.

Class Method Details

.draw_on(dc, mirror) {|dc| ... } ⇒ ::Object

Executes the given block providing a temporary (mirror) dc as it’s single argument.

Parameters:

  • dc (Wx::DC) —

    DC to duplicate the (mirrored) drawing on

  • mirror (Boolean) —

    whether to mirror or not

Yield Parameters:

Returns:

  • (::Object) —

    result of the block
