PHP Class Prado\Web\UI\JuiControls\TJuiDroppable

TJuiDroppable is an extension to {@link TActivePanel} based on jQuery-UI's {@link http://jqueryui.com/droppable/ Droppable} interaction. When a {@link TJuiDraggable} is dropped over a TJuiDroppable panel, the {@link onDrop OnDrop} event will be triggered. The event hanler will receive a {@link TJuiEventParameter} object containing a reference to the dropped control in the DraggableControl property.

drop it over me


public function drop1_ondrop($sender, $param)
{
		$draggable=$param->DraggableControl;
	$offset=$param->getCallbackParameter()->offset;
	$target=$param->getCallbackParameter()->target->offset;
	$top=$offset->top - $target->top;
	$left=$offset->left - $target->left;
	$this->label1->Text="Dropped ".$draggable->ID." at: 
Top=".$top." Left=".$left;
}
