I have an unusual situation while setting the draggable - the problem
is that containment is smaller than the draggable object. So the
draggable is visible through a "window", and the window is the
containment.
If I just set containment to that "window", trying to move the object
results in snapping object to it's lower right corner. Is there some
way to fix that behaviour?
I even tried to understand and edit the jquery-ui source code to add
this functionality, but I don't have enough experience and knowledge
in JavaScript, so it didn't work in Opera 9.2x, but works in Opera
9.5. In Opera 9.2x draggable can be moved only horizontally.
My attempt:
if(this.containment) {
/* //unchanged source version
if(position.left < this.containment[0]) position.left =
this.containment[0];
if(position.top < this.containment[1]) position.top =
this.containment[1];
if(position.left > this.containment[2]) position.left =
this.containment[2];
if(position.top > this.containment[3]) position.top =
this.containment[3];
*/
// - changed source -
if ($(o.containment).height() > this.helper.height()) {
if(position.top < this.containment[1])
position.top =
this.containment[1];
if(position.top > this.containment[3])
position.top =
this.containment[3];
} else {
if(position.top > this.containment[1])
position.top =
this.containment[1];
if(position.top < this.containment[3])
position.top =
this.containment[3];
}
if ($(o.containment).width() > this.helper.width()) {
if(position.left < this.containment[0])
position.left =
this.containment[0];
if(position.left > this.containment[2])
position.left =
this.containment[2];
} else {
if(position.left > this.containment[0])
position.left =
this.containment[0];
if(position.left < this.containment[2])
position.left =
this.containment[2];
}
// - end of changed source -
}
