Adjust widget height via javascript in DNG

Antje Rößle-Tuchel (59●4●1●5) | asked Mar 04, 2:43 a.m.

I have declared the widget height in the xml-file:

Now I want to adjust the widget height according to the height of the table via the

javascript file. I can get the table height and the widget height:

let tableHeight = tableElement.offsetHeight

console.log (tableHeight) // answer (e.g.) 412

console.log (window.innerHeight) // answer 300

But all trials to change the widget height does not work. I have tried something like:

window.reSize(200,500)

window.style.height = 500

I am looking forward to any help.

You need to use gadgets.window.adjustHeight()

Use with no argument to auto size, or use with an argument to set a specific height, eg. gadgets.window.adjustHeight(200);

thank you for the hint: but if I do so, I get the error message: Cannnot read properties of undefined (reading "adjustHeight").

OK I've just checked my widget.xml file and I have the following declared for the module

See if adding the dynamic-height feature makes the gadget work.

The other issue may be that the code is being called before the objects have been initialised. I have the gadget function calls inside an event listener hooked to 'DOMContentLoaded'

Thank you very much. The require feature in the xml-file was missing. Now it works!
