Class Ext.ux.layout.RowLayout

Package:Ext.ux.layout
Defined In:ux-all-debug.js
Class:RowLayout
Extends:Object

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
+    }]
+});
