the best method for doing this is using a slide method. if you start the slide
when the mouse goes down, the slide can be stopped if the mouse comes up before
it has finished sliding.
here's the code I knowckout out of the scrollpane:
buttonListener.onmousedown=function(e) {
var scroll=e.getTarget();
scroll["scroll"+e.getSource().direction]();
scroll.findDimensions();
};
buttonListener.onmouseup=function(e) {
e.getTarget().cancelScroll();
};
Here's the viewport code that it extends:
ViewPort.prototype.scrollUp=function() {this.scrollSlide(null,0);};
ViewPort.prototype.scrollDown=function()
{this.scrollSlide(null,-this.availableScrollY);};
ViewPort.prototype.scrollLeft=function() {this.scrollSlide(0,null);};
ViewPort.prototype.scrollRight=function()
{this.scrollSlide(-this.availableScrollX,null);};
ViewPort.prototype.scrollSlide=function(x,y) {
if (x!=null && this.enableHScroll) {
this.invokeEvent("scrollstart");
this.content.slideTo(x,this.content.y);
} else if (y!=null && this.enableVScroll) {
this.invokeEvent("scrollstart");
this.content.slideTo(this.content.x,y);
};
};
ViewPort.prototype.cancelScroll=function() {
this.content.stopSlide();
this.invokeEvent("scrollend");
};
Hope this is of some use.
