---|
| 222 | * --------------------- |
---|
| 223 | * |
---|
| 224 | * It is recommended that you add the custom buttons in an external |
---|
| 225 | * file and leave this one unchanged. That's because when we |
---|
| 226 | * (InteractiveTools.com) release a new official version, it's less |
---|
| 227 | * likely that you will have problems upgrading HTMLArea. |
---|
| 228 | * |
---|
| 229 | * Example on how to add a custom button when you construct the HTMLArea: |
---|
| 230 | * |
---|
| 231 | * var editor = new HTMLArea("your_text_area_id"); |
---|
| 232 | * var cfg = editor.config; // this is the default configuration |
---|
| 233 | * cfg.btnList["my-hilite"] = |
---|
| 234 | * [ function(editor) { editor.surroundHTML('<span style="background:yellow">', '</span>'); }, // action |
---|
| 235 | * "Highlight selection", // tooltip |
---|
| 236 | * "my_hilite.gif", // image |
---|
| 237 | * false // disabled in text mode |
---|
| 238 | * ]; |
---|
| 239 | * cfg.toolbar.push(["linebreak", "my-hilite"]); // add the new button to the toolbar |
---|
| 240 | * |
---|
| 241 | * An alternate (also more convenient and recommended) way to |
---|
| 242 | * accomplish this is to use the registerButton function below. |
