1 /*
2 * Experimental code to use operators for constraint specification.
3 * In the end, the syntax didn't look much clearer than
4 * the original, so abandoned.

6 Example:
7
8 wxConstrain(frame->panel,
9
10 ( leftOf (frame->panel) = leftOf (frame),
11 topOf (frame->panel) = topOf (frame),
12 rightOf (frame->panel) = rightOf (frame),
13 heightOf (frame->panel) = 50 % heightOf (frame)
14 )
15 );
