Function Documentation

◆ block_align_proximity_compute()

static void block_align_proximity_compute	(	ButAlign *	butal,
		ButAlign *	butal_other )

static

This function checks a pair of buttons (assumed in a same align group), and if they are neighbors, set needed data accordingly.

Note: It is designed to be called in total random order of buttons. Order-based optimizations are done by caller.

Definition at line 120 of file interface_align.cc.

		const int	side,

This function takes care of case described in this schema:

+-----------+-----------+
|   BUT 1   |   BUT 2   |
|-----------------------+
|   BUT 3   |
+-----------+

Here, BUT 3 RIGHT side would not get 'dragged' to align with BUT 1 RIGHT side, since BUT 3 has not RIGHT neighbor. So, this function, when called with BUT 1, will 'walk' the whole column in side_s1 direction (TOP or DOWN when called for RIGHT side), and force buttons like BUT 3 to align as needed, if BUT 1 and BUT 3 were detected as needing top-right corner stitching in block_align_proximity_compute() step.
