Getting resize events from js [message #991820]

Hi, I'm trying to build a custom widget based on the custom widget template from https://github.com/tbuschto/customWidgetTemplate. Up to now almost everything worked quite well.
There is just one thing I couldn't figure out up to now and I was wondering if anyone here could give me a hint on how to solve this.
How can I get a resize event in the javascript when the widget is resized? I need to resize the contents of the widget when the widget is resized and since there is no need to communicate with the server I thought it would be best to do this in the js.

Thanks in advance for any help or hints.

Christian

Hi.

As far as i know there is no way to get a resize event directly from a
DOM element. The quick solution would be to only use % or set it from
the server. But perhaps this is something where RAP API should support a
custom widget developer with a resize event. If you think so, open an
enhancement request on the RAP bugzilla where we could discuss this.

Thanks,
Tim

Hi.

For your information, this is now supported in RAP master.
The Composite has three new methods, I'm posting the JsDoc since it's
not yet in the developers guide:

/**
* @name getClientArea
* @function
* @memberOf Composite#
* @description Returns the client Area of the Composite
* @returns {int[]} the client area as array [ x, y, width, height ]
*/

/**
* @name addListener
* @function
* @memberOf Composite#
* @description Register the function as a listener of the given type
* @param {string} type The type of the event (e.g. "Resize").
* @param {Function} listener The callback function
*/

/**
* @name removeListener
* @function
* @memberOf Composite#
* @description De-register the function as a listener of the given type
* @param {string} type The type of the event (e.g. "Resize").
* @param {Function} listener The callback function
*/

Greetings,
Tim
