Class Ext.layout.BorderLayout

Package:Ext.layout
Defined In:BorderLayout.js
Class:BorderLayout
Extends:ContainerLayout

This is a multi-pane, application-oriented UI layout style that supports multiple nested panels, automatic split bars between regions and built-in expanding and collapsing of regions.

This class is intended to be extended or created via the layout:'border' Ext.Container.layout config, and should generally not need to be created directly via the new keyword.

BorderLayout does not have any direct config options (other than inherited ones). All configuration options available for customizing the BorderLayout are at the Ext.layout.BorderLayout.Region and Ext.layout.BorderLayout.SplitRegion levels.

Example usage:

var myBorderPanel = new Ext.Panel({
    renderTo: document.body,
    width: 700,
    height: 500,
    title: 'Border Layout',
    layout: 'border',
    items: [{
        title: 'South Region is resizable',
        region: 'south',     // position for region
        height: 100,
        split: true,         // enable resizing
        minSize: 75,         // defaults to 50 
        maxSize: 150,
        margins: '0 5 5 5'
    },{
        // xtype: 'panel' implied by default
        title: 'West Region is collapsible',
        region:'west',
        margins: '5 0 0 5',
        width: 200,
        collapsible: true,   // make collapsible
        cmargins: '5 5 0 5', // adjust top margin when collapsed
        id: 'west-region-container',
        layout: 'fit',
        unstyled: true
    },{
        title: 'Center Region',
        region: 'center',     // center region is required, no width/height specified
        xtype: 'container',
        layout: 'fit',
        margins: '5 5 0 0'
    }]
});

Notes:

  • Any container using the BorderLayout must have a child item with region:'center'. The child item in the center region will always be resized to fill the remaining space not used by the other regions in the layout.
  • Any child items with a region of west or east must have width defined (an integer representing the number of pixels that the region should take up).
  • Any child items with a region of north or south must have height defined.
  • The regions of a BorderLayout are fixed at render time and thereafter, its child Components may not be removed or added. To add/remove Components within a BorderLayout, have them wrapped by an additional Container which is directly managed by the BorderLayout. If the region is to be collapsible, the Container used directly by the BorderLayout manager should be a Panel. In the following example a Container (an Ext.Panel) is added to the west region:
    wrc = Ext.getCmp('west-region-container');
    wrc.removeAll();
    wrc.add({
        title: 'Added Panel',
        html: 'Some content'
    });
    wrc.doLayout();
  • To reference a Region:
    wr = myBorderPanel.layout.west;
