panning and zoomin and out, and ect

[Fawcett, David]

Albert, 
 
You may want to look at how it is done in the dBox interface.

In fact, you may just want to use dBox or modify it.

	Hi,
	
	Its not working cause It doesnt do anything when I click the button.  I got know if I want my number to go negative. I am new to this.  You told me to try this i would try
	if(direction=='nw'){
	x = 1;
	y = 1;
	}
	
	so do I change my code that I have?  else if(direction== 'nw') {
	   x = 0 + (309 * pansize)/2.0;
	   y = 0 + (309 * pansize)/2.0;
	
	I dont know what I am doing?Could you help me?
	
	Thanks,
	Albert

		hi, can you give more info on how it is not working?
		what happens?
		you may want to check what x and y are coming out as.
		often + will concatenate numbers instaed of adding.
		
		also, are you sure you want x and y to go negative as you
		have made them in 'nw' for example?
		
		i would try
		if(direction=='nw'){
		x = 1;
		y = 1;
		}
		which i think should recenter you on the upper left corner of the map.
