问题 What is the difference between a sub-object and a contained object ? For constructing an instance of a class which is derived from another class, first the sub-object has to be created and then the derived object has to be created. Questions: Is it true that derived object contains the sub-object? How can one visualize the difference in the structure of an object a) which contains another object b) which is derived from another class Do the objects in a) and b) have the same structure ? 回答1:

JQuery UI draggable: Exceed containment on one side

由 寵の児 提交于 2020-01-01 05:05:09
问题 I am using JQuery UI to implement resizable/draggable elements. Now I would like to define a containment for these elements that limits the resizing/dragging on exactly three(!) sides. E.g. have a look at this JSFiddle example. You can see that the contained element can only be resized/dragged inside the parent's area. What I would like to achieve is that the element can exceed the bottom threshold and be moved to beyond the bottom border of the parent. Nevertheless the resizing/dragging

Restrict jQuery draggable items from overlapping/colliding with sibling elements

由 ぃ、小莉子 提交于 2019-12-28 02:06:32
问题 I need to use jQuery UI to restrict the containment area for draggable object with some additional restriction. I need prevent the draggable element from overlapping with other elements within the same container. I need to allow movement in "moveInHere" area but not "butNotHere" area. Is it possible? <div id="moveInHere"> <div id="dragMe"> </div> <div id="butNotHere"> </div> </div> <script type="text/javascript"> $("#dragMe").draggable({ containment: "#moveInHere" }); </script> 回答1: Edit: New

Create instance of generic type in Java when parameterized type is contained?

问题 This is a follow-up to my question: Create instance of generic type in Java when parameterized type passes through hierarchies? For attempting to create a new generic from a contained class, I tried to adapt Steve B's approach of creating an anonymous subclass: import java.lang.reflect.Constructor; import java.lang.reflect.InvocationTargetException; import java.lang.reflect.ParameterizedType; import java.lang.reflect.Type; public class ParameterizedTypeEg { ParameterizedTypeEg () {

default implementation of an interface that is used as a contained component

问题 I have an interface IFoo for which I want to provide a default implementation Foo. Foo can be used as a contained class/component by other classes that implement IFoo. IFoo is used by several classes that mostly implement it by forwarding calls to Foo, but for some methods they may provide their own implementation. Foo needs access to (private) members of the calling class. Passing these members as arguments in method calls is not possible because they are not (and should not be) part of the

问题 I have a UIViewController (red) set as the first tab of a UITabBarController as shown in the storyboard below. This view controller is a container view controller and loads a UINavigationController inside its contentView (the white rectangle inside the red view controller).
