---|
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. |
