Forum > on resize for regions?

07-07-2019, 09:40 PM:

Standard HTML+JS only provides resize events for windows and frames. However Intraweb also resizes controls using the align functionality. (e.g. when a splitter is used)

There are a couple of places where I've embedded content that needs to be notified of resize so they can redraw themselves. I've got the following code in one such place:

Code:

window.resize(function(){

CurDgm.PanZoom.resize();

CurDgm.PanZoom.fit();

CurDgm.PanZoom.center();

});

That code works as expected when the browser is resized. However, when a splitter is used that causes the containing region to change size, that function will not be called.

Is there an IW event handler I can hook to to call this code when a region changes size?

Thanks!

Did you figure this out yet Pete?

You can resolve this using this update (or later version eventually):

https://downloads.atozed.com/intraweb/iw..._BETA2.exe

Then you can add code like this to any IW control which is aligned (and is resized by the splitter). In this case is IWRegion1 region:

procedure TIWForm1.IWAppFormRender(Sender: TObject);

var

js: string;

begin

js := 'var el = IW.$("IWREGION1");' +

'el.OnAfterResize = function (rect) {' +

'alert("IWREGION1 has been resized");' +

'}';

AddToInitProc(js);

end;
