This is a very simple layout style used to center contents within a container. This layout works within * nested containers and can also be used as expected as a Viewport layout to center the page layout.
*As a subclass of FitLayout, CenterLayout expects to have a single child panel of the container that uses * the layout. The layout does not require any config options, although the child panel contained within the * layout must provide a fixed or percentage width. The child panel's height will fit to the container by * default, but you can specify autoHeight:true to allow it to autosize based on its content height. * Example usage:
*
// The content panel is centered in the container
var p = new Ext.Panel({
title: 'Center Layout',
layout: 'ux.center',
items: [{
title: 'Centered Content',
width: '75%',
html: 'Some content'
}]
});
// If you leave the title blank and specify no border
// you'll create a non-visual, structural panel just
// for centering the contents in the main container.
var p = new Ext.Panel({
layout: 'ux.center',
border: false,
items: [{
title: 'Centered Content',
width: 300,
autoHeight: true,
html: 'Some content'
}]
});

* ================ RowLayout =======================
*/
/**
* @class Ext.ux.layout.RowLayout
* @extends Ext.layout.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' {@link 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
}]
});
