Re: [jQuery] interface: how to get canvas elements to stay visible while dragging

2006-10-25 Thread Andy Triboletti 
Nah, I'm not talking about ghosting.  The problem I have is that the  
canvas element doesn't show up while performing the drag operation  
(with ghosting: true, or not).  Here's an example

Are you referring to ghosting like in the demo?

[jQuery] interface: how to get canvas elements to stay visible while dragging?

2006-10-25 Thread Andy Triboletti 
I would like to drag a canvas element around, and have the screen updated while dragging it like it does with a div.  The code below lets me drag the canvas, but the screen does not update while the drag is happening, it only displays the rectangle after the drop.  The canvas disapears while the drag is happening.  Does anyone have any ideas about how to do this, maybe using onDrag?  
Thanks!
canvas = document.createElement("canvas");canvas.setAttribute('id', 'canvas');ctx = canvas.getContext("2d");canvas.height=300;canvas.width=300;ctx.fillRect (10, 10, 55, 50);
document.body.appendChild(canvas);$('#canvas').Draggable();
