Raw Normal View History

Big update for the editor! Code is closer to HTMLArea 3.0 RC1. - Updated dialog behavior (no more showModalDialogs) - Cleaner XHTML coding in dialogs - Unnecessary comment stripped off from htmlarea.php - New anchor feature.

/* ADDING CUSTOM BUTTONS

* file and leave this one unchanged. That's because when we

* 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.
