the resolved pixel width of each column for a given total width
The rectangle of a cell, spanning columnSpan columns and rowSpan rows. Out-of-range cells
resolve to a zero-sized rect at the far edge rather than throwing, so a caller walking a
changing table never has to bounds-check first.
the resolved pixel height of each row for a given total height
A column/row grid whose tracks are
sizeorgrow, the data-driven counterpart to GUI2's[grid]. Fixed tracks take their size; the rest of the space is divided between thegrowtracks in proportion to their weight, so a sidebar can besize: 200and the contentgrow: 1without either side knowing the window's width.Example
