I am trying to test for window.PointerEvent in some external javascript
so that I can get touch working in IE but it never appears to be defined.

Is fact the window object that I am accessing in the javascript does not
appear to be the standard browser window but a different class altogether.

Is there any way to access the browser window object from external
javascript with EWB?

Code please.

It's possible that some JS has messed with the namespace in such a way as to
make it different, but that's a pretty odd thing to do.

It should be defined as just:

window

as a global variable.

I am just testing if the pointer events are supported indicating IE 11
using the following and setting the style to contain touch-action : none

if (window.PointerEvent)
   signaturec.setAttribute("style","touch-action: none;");

If I run my extrenal javascript from Expression Web 4 then
if(window.PointerEvent) returns true so I set the Canvas style to
contain "touch-action: none" and the canvas then doesn't try and pan
around when I touch it using IE.

If I test window.PointerEvent from EWB it doesn't exist.

Trying to set the "touch-action:none" style anyway doesn't appear to
stop the panning even if I just set it and bypass the test for
window.PointerEvent

Chris,

<< if (window.PointerEvent)
signaturec.setAttribute("style","touch-action: none;"); >>

PointerEvent is not defined in the TWindow external interface in EWB, so it
won't be accessible at all.  You'll have to modify the TWindow external
interface in the WebDOM unit and add the appropriate property in order to
use it with EWB.

I'd have to see how you're setting it as an in-line style.  It's a CSS
property, so inline styles should work with it.

I am setting it lke this

signaturec.setAttribute("style","touch-action: none;");

Chris,

signaturec.setAttribute("style","touch-action: none;"); >>

That should work fine.  And signaturec is the canvas element, I assume ?

Yes, I will see if I can know up a small test project for this on
Thursday (I am off work tomorrow)

I have emailed a small demo project that shows this happening (hopefully)
