Setting up the Editor's HTML
Setting up the Editor's HTML is done by creating a textarea control on the page.
Setting up the Editor's Javascript
Once the textarea is on the page, then initialize the Editor like this:
Creating the Toolbar Button and Menu
Now we can create a button and add it to the Editor's Toolbar. First we subscribe to the Editor's toolbarLoaded Custom Event.
From inside that function we will setup a new button config object literal with the following properties:
- type: (push, menu, split, spin, select, color)
- label: The text string displayed on the button
- value: The value is also called the Command for the button.
- menu: A
YAHOO.widget.Overlay instance to be used as a menu.
Now add it to the Toolbar group called "insertitem" like this: myEditor.toolbar.addButtonToGroup(imgConfig, 'insertitem');
Styling the Button
There are 2 important states to style a button in the toolbar.
First is the default state, that can be accessed via this CSS rule: .yui-toolbar-container .yui-toolbar-inserticon span.yui-toolbar-icon
Second is the selected state, that can be accessed via this CSS rule: .yui-toolbar-container .yui-button-inserticon-selected span.yui-toolbar-icon
.yui-toolbar-container is the class applied to the top-most container of the toolbar.
.yui-toolbar-icon is an extra SPAN injected into the button for spriting an image.
.yui-toolbar-VALUE is a dynamic class added to the button based on the value passed into the buttons config. It is used for specific styling of a button that may appear in several places on the page.
