Hi Everyone,
I just want to have a script that takes a widget and enables the
ability to drag it around the screen. This should be relatively
simple, but my code is having some problems. For this simple
example, im just using a QxAtom. When I click it, i am allowed to
drag it for a very short space (10 pixels or so) and then it freezes
until I click on it again.
I wrote alternative code where the mousedown function toggled the
status of "capture" so that I could click on the widget, move it
around, and click again to release it. This will do for now, but I
would really like the concept of "dragging" while the mouse is pushed
down. Can anyone see whats wrong?
To see it in action, visit www.laststopstudios.com/icoti/icoti.html
here is my current code.
window.application.main = function()
{
var d = this.getClientWindow().getClientDocument();
var w1 = new QxAtom("drag me");;
w1.setBackgroundColor("#222200");
w1.setTop(0);
w1.setLeft(0);
w1.setWidth(100);
w1.setHeight(100);
w1.addEventListener("dragstart", handleDragStart);
w1.addEventListener("dragend", handleDragEnd);
w1.addEventListener("mousedown", handleMouseDown);
w1.addEventListener("mousemove", handleMouseMove);
w1.addEventListener("mouseup", handleMouseUp);
function handleDragStart(e)
{
e.addData("text/plain", "Plain text");
e.addAction("copy");
e.addAction("move");
e.addAction("alias");
e.startDrag();
};
function handleDragEnd(e){
};
function handleMouseDown(e)
{
this.setCapture(true);
};
function handleMouseMove(e)
{
if (this.getCapture())
{
this.setLeft(e.getPageX() - 50);
this.setTop(e.getPageY() - 50);
}
};
function handleMouseUp(e)
{
this.setCapture(false);
};
d.add(w1);
}
