TUniCustomHTMLFrame and Resize events for custom controls ?

[CastleSoft]

I have a custom control based on TUniCustomHTMLFrame  which works with a <canvas> element.

 

I have a Javascript function called resizeCanv() which is as follows:

 

function resizeCanv(){

   var canvas = $( "canvas#'+JSName+'" )[0];

   canvas.width = canvas.parentElement.clientWidth;

   canvas.height = canvas.parentElement.clientHeight;

 }

 

In my TUniFAKECanvas controls .create the  HTML.Text is set to <canvas id="'+JSName+'"></canvas> 

and the resizeCanv() is called.

 

It all works great.

 

I then added the Align to allow me to use 'client' for sizing.

 

When the form is resized, the HTMLFrame resizes ok, but I need to call my resizeCanv() javascript function.

 

Inside the custom control, what should I hook / trap and whats the recommended way inside a custom control to trap a forms align=client

so the child controls can be resized/moved etc ?

 

Thanks
