Re: Not sure how to get the correct size of Canvas

Depending on your game, you might want to have fixed setCoordinateSpaceHeight / setCoordinateSpaceWidth sizes, so every device gets the same game detail (plus make programming the game easier).  Then set the width and height of the canvas element to fit the screen size:

canvas.getElement().getStyle().setWidth(xxx, Unit.PX);
canvas.getElement().getStyle().setHeight(xxx, Unit.PX);

Ahh, got it.

 

I called the get offset width and height in onAttachOrDetach and
then multiplied those values by a constant and called the setCoordinateSpace
methods.  Now it makes sense.

 

It is interesting the ClickEvent.getX() and getY() are giving me coordinates in the
screen space instead of the coordinate space, but that is an easy multiplication
to do.

 

Thank you,
