8 | * @class Ext.form.HtmlEditor |
---|
9 | * @extends Ext.form.Field |
---|
10 | * Provides a lightweight HTML Editor component. Some toolbar features are not supported by Safari and will be |
---|
11 | * automatically hidden when needed. These are noted in the config options where appropriate. |
---|
12 | * <br><br>The editor's toolbar buttons have tooltips defined in the {@link #buttonTips} property, but they are not |
---|
13 | * enabled by default unless the global {@link Ext.QuickTips} singleton is {@link Ext.QuickTips#init initialized}. |
---|
14 | * <br><br><b>Note: The focus/blur and validation marking functionality inherited from Ext.form.Field is NOT |
---|
15 | * supported by this editor.</b> |
---|
16 | * <br><br>An Editor is a sensitive component that can't be used in all spots standard fields can be used. Putting an Editor within |
---|
17 | * any element that has display set to 'none' can cause problems in Safari and Firefox due to their default iframe reloading bugs. |
---|
18 | * <br><br>Example usage: |
---|
19 | * <pre><code> |
---|
20 | // Simple example rendered with default options: |
---|
21 | Ext.QuickTips.init(); // enable tooltips |
---|
22 | new Ext.form.HtmlEditor({ |
---|
23 | renderTo: Ext.getBody(), |
---|
24 | width: 800, |
---|
25 | height: 300 |
---|
26 | }); |
---|
27 | |
---|
28 | // Passed via xtype into a container and with custom options: |
---|
29 | Ext.QuickTips.init(); // enable tooltips |
---|
