The - * layout will use the columnWidth (if present) or width of each panel during layout to determine how to size each panel. - * If width or columnWidth is not specified for a given panel, its width will default to the panel's width (or auto).

- *The basic rules for specifying column widths are pretty simple. The logic makes two passes through the - * set of contained panels. During the first layout pass, all panels that either have a fixed width or none - * specified (auto) are skipped, but their widths are subtracted from the overall container width. During the second - * pass, all panels with columnWidths are assigned pixel widths in proportion to their percentages based on - * the total remaining container width. In other words, percentage width panels are designed to fill the space - * left over by all the fixed-width and/or auto-width panels. Because of this, while you can specify any number of columns - * with different percentages, the columnWidths must always add up to 1 (or 100%) when added together, otherwise your - * layout may not render as expected.
