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'
    }]
});
*/ Ext.ux.layout.CenterLayout = Ext.extend(Ext.layout.FitLayout, { // private setItemSize : function(item, size){ this.container.addClass('ux-layout-center'); item.addClass('ux-layout-center-item'); if(item && size.height > 0){ if(item.width){ size.width = item.width; } item.setSize(size); } } }); Ext.Container.LAYOUTS['ux.center'] = Ext.ux.layout.CenterLayout; /* * CenterLayout demo panel */ var centerLayout = { id: 'center-panel', layout:'ux.center', items: { title: 'Centered Panel: 75% of container width and fit height', layout: 'ux.center', autoScroll: true, width: '75%', bodyStyle: 'padding:20px 0;', items: [{ title: 'Inner Centered Panel', html: 'Fixed 300px wide and auto height. The container panel will also autoscroll if narrower than 300px.', width: 300, frame: true, autoHeight: true, bodyStyle: 'padding:10px 20px;' }] } }; /* * ================ 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
    }]
});
