Class Ext.layout.ColumnLayout

Package:Ext.layout
Defined In:ColumnLayout.js
Class:ColumnLayout
Extends:ContainerLayout

This is the layout style of choice for creating structural layouts in a multi-column format where the width of -each column can be specified as a percentage or fixed width, but the height is allowed to vary based on the content. -This class is intended to be extended or created via the layout:'column' Ext.Container.layout config, -and should generally not need to be created directly via the new keyword.

-

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
-    }]
-});
