I don't want to discourage you from trying your own implementation but youmight want to take a look at Lienzo and see if it works for what you need. It's 100% built on GWT and lighting fast. It should do all the things you will need and likely more. It's released under Apache.Explorer:Download:Best regards,Alfredo--On Thu, Nov 29, 2012 at 1:29 PM, Matt Fair <matt.fair@gmail.com> wrote:
I have the following code:
public void draw(Context2d context) {
context.beginPath();
context.rect(x, y, width, height);
context.fill();
context.closePath();
context.stroke();}
I would like to add a mouse event for when the mouse moves over the rectangle. What's the best way to do this? I was able to do it if I in the mouse move event for the canvas and with an if statement I checked to see if the mouse moved within the coordinates of the rectangle.
canvas.addMouseMoveHandler(new MouseMoveHandler() {
public void onMouseMove(MouseMoveEvent event) {
mouseX = event.getRelativeX(canvas.getElement());
mouseY = event.getRelativeY(canvas.getElement());if(insideRectangle(mouseX, mouseY)) {
// fire mouse event for rectangle
}
}
});
However, I am worry about working with a bunch of objects and speed doing it this way. Is there a way to add a mouseMoveHandler directly to the rectangle?
Thanks,
Matt
