// We are adding these custom layouts to a namespace that does not// exist by default in Ext, so we have to add the namespace first:Ext.ns('Ext.ux.layout');/* * ================  CenterLayout  ======================= *//** * @class Ext.ux.layout.CenterLayout * @extends Ext.layout.FitLayout * <p>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.</p> * <p>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 <tt>autoHeight:true</tt> to allow it to autosize based on its content height.   * Example usage:</p>  * <pre><code>// The content panel is centered in the containervar 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'    }]});</code></pre> */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 * <p>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.</p> * <p>RowLayout does not have any direct config options (other than inherited ones), but it does support a * specific config property of <b><tt>rowHeight</tt></b> 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).</p> * <p>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).</p> * <p>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 <b>remaining</b> 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:</p> * <pre><code>// All rows are percentages -- they must add up to 1var 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    }]});</code></pre> */Ext.ux.layout.RowLayout = Ext.extend(Ext.layout.ContainerLayout, {    // private    monitorResize:true,    // private    isValidParent : function(c, target){        return c.getEl().dom.parentNode == this.innerCt.dom;    },    // private    onLayout : function(ct, target){        var rs = ct.items.items, len = rs.length, r, i;        if(!this.innerCt){            target.addClass('ux-row-layout-ct');            this.innerCt = target.createChild({cls:'x-row-inner'});        }        this.renderAll(ct, this.innerCt);        var size = target.getViewSize();        if(size.width < 1 && size.height < 1){ // display none?            return;        }        var h = size.height - target.getPadding('tb'),            ph = h;        this.innerCt.setSize({height:h});                // some rows can be percentages while others are fixed        // so we need to make 2 passes                for(i = 0; i < len; i++){            r = rs[i];            if(!r.rowHeight){                ph -= (r.getSize().height + r.getEl().getMargins('tb'));            }        }        ph = ph < 0 ? 0 : ph;        for(i = 0; i < len; i++){            r = rs[i];            if(r.rowHeight){                r.setSize({height: Math.floor(r.rowHeight*ph) - r.getEl().getMargins('tb')});            }        }    }        /**     * @property activeItem     * @hide     */});Ext.Container.LAYOUTS['ux.row'] = Ext.ux.layout.RowLayout;/* * RowLayout demo panel */var rowLayout = {	id: 'row-panel',	bodyStyle: 'padding:5px',	layout: 'ux.row',    title: 'Row Layout',    items: [{        title: 'Height = 25%, Width = 50%',        rowHeight: .25,        width: '50%'    },{        title: 'Height = 100px, Width = 300px',        height: 100,        width: 300    },{    	title: 'Height = 75%, Width = fit',    	rowHeight: .75    }]};
