- *ColumnLayout does not have any direct config options (other than inherited ones), but it does support a - * specific config property of columnWidth that can be included in the config of any panel added to it. 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 width property is always evaluated as pixels, and must be a number greater than or equal to 1. - * The columnWidth property is always evaluated as a percentage, and must be a decimal value greater than 0 and - * less than 1 (e.g., .25).
- *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. Example usage:
- *+ +-// All columns are percentages -- they must add up to 1 -var p = new Ext.Panel({ - title: 'Column Layout - Percentage Only', - layout:'column', - items: [{ - title: 'Column 1', - columnWidth: .25 - },{ - title: 'Column 2', - columnWidth: .6 - },{ - title: 'Column 3', - columnWidth: .15 - }] -}); - -// Mix of width and columnWidth -- all columnWidth values must add up -// to 1. The first column will take up exactly 120px, and the last two -// columns will fill the remaining container width. -var p = new Ext.Panel({ - title: 'Column Layout - Mixed', - layout:'column', - items: [{ - title: 'Column 1', - width: 120 - },{ - title: 'Column 2', - columnWidth: .8 - },{ - title: 'Column 3', - columnWidth: .2 - }] -}); -/** + * @class Ext.grid.ColumnLayout + * @extends Ext.layout.container.HBox + * @private + * + * <p>This class is used only by the grid's HeaderContainer docked child.</p> + * + * <p>This class adds the ability to shrink the vertical size of the inner container element back if a grouped + * column header has all its child columns dragged out, and the whole HeaderContainer needs to shrink back down.</p> + * + * <p>It also enforces the grid's HeaderContainer's forceFit config by, after every calaculateChildBoxes call, converting + * all pixel widths into flex values, so that propertions are maintained upon width change of the grid.</p> + * + * <p>Also, after every layout, after all headers have attained their 'stretchmax' height, it goes through and calls + * <code>setPadding</code> on the columns so that they lay out correctly.
