This layout manager is specifically designed for rendering and managing child Components of - * {@link Ext.form.FormPanel forms}. It is responsible for rendering the labels of - * {@link Ext.form.Field Field}s.
- * - *This layout manager is used when a Container is configured with the layout:'form' - * {@link Ext.Container#layout layout} config option, and should generally not need to be created directly - * via the new keyword. See {@link Ext.Container#layout} for additional details.
- * - *In an application, it will usually be preferrable to use a {@link Ext.form.FormPanel FormPanel} - * (which is configured with FormLayout as its layout class by default) since it also provides built-in - * functionality for {@link Ext.form.BasicForm#doAction loading, validating and submitting} the form.
- * - *A {@link Ext.Container Container} using the FormLayout layout manager (e.g. - * {@link Ext.form.FormPanel} or specifying layout:'form') can also accept the following - * layout-specific config properties:
Any Component (including Fields) managed by FormLayout accepts the following as a config option: - *
Any Component managed by FormLayout may be rendered as a form field (with an associated label) by - * configuring it with a non-null {@link Ext.Component#fieldLabel fieldLabel}. Components configured - * in this way may be configured with the following options which affect the way the FormLayout renders them: - *
Example usage:
- *
-// Required if showing validation messages
-Ext.QuickTips.init();
-
-// While you can create a basic Panel with layout:'form', practically
-// you should usually use a FormPanel to also get its form functionality
-// since it already creates a FormLayout internally.
-var form = new Ext.form.FormPanel({
- title: 'Form Layout',
- bodyStyle: 'padding:15px',
- width: 350,
- defaultType: 'textfield',
- defaults: {
- // applied to each contained item
- width: 230,
- msgTarget: 'side'
- },
- items: [{
- fieldLabel: 'First Name',
- name: 'first',
- allowBlank: false,

- layoutConfig: {
- {@link #labelSeparator}: '~' // superseded by assignment below
- },
- // config options applicable to container when layout='form':
- hideLabels: false,
- labelAlign: 'left', // or 'right' or 'top'
- {@link Ext.form.FormPanel#labelSeparator labelSeparator}: '>>', // takes precedence over layoutConfig value
- labelWidth: 65, // defaults to 100
- labelPad: 8 // defaults to 5, must specify labelWidth to be honored
-});
