HtmlLayout is an editable grid layout system using HTML tables, allowing for more complex GUIs to be developed more easily or at least in a more automated fashion. Note: Always reads from top-down *then* left to right. Take for example the following 3 x 3 grid:
a1 | b1 | c1
----+----+----
a2 | b2 | c2
----+----+----
a3 | b3 | c3
This grid can also be expressed as:
0,0 | 1,0 | 2,0
-----+-----+-----
0,1 | 1,1 | 2,1
-----+-----+-----
0,2 | 1,2 | 2,2
This would read a1, a2, a3, b1, b2, b3, etc. Be mindful of this when looping. Also of note when referring to cells is that you can refer to them in two different ways. The 'a1' notation is acceptable, and you can also pass an array of two values containing the column (x) and row (y) position of the cell. Please note that the first notation starts at 'a' and '1', but the second way starts at (0, 0). You can use the translate() method to convert between the two. Also note that there is a cell limit of 701 cols (from a to zz), regardless of which way you refer to them. This is probably way more than you should ever need anyway. However, should you need more columns, you can use the sub() method to create sub-layouts inside any cell for practically unlimited depth. There is no limit on the number of rows available. New in 1.2: - Fixed a bug in the render() output that was causing some cells not to appear.
- Increased the column limit from 26 to 701.
