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'
- }]
-});
-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
- }]
-});
