on resize for regions? - pete@pdmagic.com - 07-07-2019
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/iw15.2.54_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;
