To learn more about the event argument for a specific component's callback function,

see the property page for that component. Right-click the component, and select Help on

Selection to open the property page. For a list of property pages for all UI components,

see “Designing Apps in App Designer”.

Searching for Callbacks in Your Code

If your app has a lot of callbacks, you can quickly search and navigate to a specific

callback by typing part of the name in the search bar at the top of the Callbacks tab in

the Code Browser. After you begin typing, the Callbacks pane clears, except for the

callbacks that match your search.

Click a search result to scroll the callback into view. Right-clicking a search result and

selecting Go To places your cursor in the callback function.

Deleting Callbacks

Delete a callback by right-clicking the callback in the Callbacks tab of the Code

Browser and selecting Delete from the context menu.
