# Class Ext.ux.layout.RowLayout

Package: | Ext.ux.layout
Defined In: | RowLayout.js
Class: | RowLayout
Extends: | ContainerLayout

This is the layout style of choice for creating structural layouts in a multi-row format where the height of each row can be specified as a percentage or fixed height. Row widths can also be fixed, percentage or auto. This class is intended to be extended or created via the layout:'ux.row' Ext.Container.layout config, and should generally not need to be created directly via the new keyword.

RowLayout does not have any direct config options (other than inherited ones), but it does support a specific config property of `rowHeight` that can be included in the config of any panel added to it. The layout will use the rowHeight (if present) or height of each panel during layout to determine how to size each panel. If height or rowHeight is not specified for a given panel, its height will default to the panel's height (or auto).

The height property is always evaluated as pixels, and must be a number greater than or equal to 1. The rowHeight 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 row heights 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 height or none specified (auto) are skipped, but their heights are subtracted from the overall container height. During the second pass, all panels with rowHeights are assigned pixel heights in proportion to their percentages based on the total remaining container height. In other words, percentage height panels are designed to fill the space left over by all the fixed-height and/or auto-height panels. Because of this, while you can specify any number of rows with different percentages, the rowHeights must always add up to 1 (or 100%) when added together, otherwise your layout may not render as expected. Example usage:

    // All rows are percentages -- they must add up to 1
    var p = new Ext.Panel({
        title: 'Row Layout - Percentage Only',
        layout:'ux.row',
        items: [{
            title: 'Row 1',
            rowHeight: .25
        },{
            title: 'Row 2',
            rowHeight: .6
        },{
            title: 'Row 3',
            rowHeight: .15
        }]
    });

    // Mix of height and rowHeight -- all rowHeight values must add
    // up to 1. The first row will take up exactly 120px, and the last two
    // rows will fill the remaining container height.
    var p = new Ext.Panel({
        title: 'Row Layout - Mixed',
        layout:'ux.row',
        items: [{
            title: 'Row 1',
            height: 120,
            // standard panel widths are still supported too:
            width: '50%' // or 200
        },{
            title: 'Row 2',
            rowHeight: .8,
            width: 300
        },{
            title: 'Row 3',
            rowHeight: .2
        }]
    });

An optional extra CSS class that will be added to the container. This can be useful for adding customized styles to the container or any of its children using standard CSS rules. See Ext.Component.ctCls also. Note: `extraCls` defaults to `''` except for the following classes which assign a value by default: Absolute Layout : `'x-abs-layout-item'` Box Layout : `'x-box-item'` Column Layout : `'x-column'` To configure the above Classes with an extra CSS class append to the default. For example, for ColumnLayout:
    extraCls: 'x-column custom-class'

| renderHidden : Boolean True to hide each contained item on render (defaults to false). | ContainerLayout
