- *
- * 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.

+ /* 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.
