/* ADDING CUSTOM BUTTONS
|
|
* ---------------------
|
|
*
|
|
* It is recommended that you add the custom buttons in an external
|
|
* file and leave this one unchanged. That's because when we
|
|
* (InteractiveTools.com) release a new official version, it's less
|
|
* likely that you will have problems upgrading HTMLArea.
|
|
*
|
|
* Example on how to add a custom button when you construct the HTMLArea:
|
|
*
|
|
* var editor = new HTMLArea("your_text_area_id");
|
|
* var cfg = editor.config; // this is the default configuration
|
|
* cfg.btnList["my-hilite"] =
|
|
* [ function(editor) { editor.surroundHTML('<span style="background:yellow">', '</span>'); }, // action
|
|
* "Highlight selection", // tooltip
|
|
* "my_hilite.gif", // image
|
|
* false // disabled in text mode
|
|
* ];
|
|
* cfg.toolbar.push(["linebreak", "my-hilite"]); // add the new button to the toolbar
|
|
*
|
|
* An alternate (also more convenient and recommended) way to
|
|
* accomplish this is to use the registerButton function below.
