移动控件时，将控件置于下方 [英] While moving a control get the control underneath

问题描述

大家好，

我拥有一个控制权(打牌)，无法在面板上自由移动.
移动此卡时，我需要知道是否还有另一个控件以及面板上的哪个控件.

我无法使用mouseenter或muosehover，因为按下鼠标按钮时此事件不起作用.

谢谢你的帮助

推荐答案

如果您拥有扁平的控件结构，则始终可以使用控件的Parent.Controls来获取所有对等项.使用该控件集合，您可以获取与之相交或包含以下内容的所有控件:

If you have a flat structure of controls, you can always yous your control''s Parent.Controls to get all peers. With that collection of controls you can get all controls your control intersects with or contain:

Control myMovingControl = //...

Rectangle currentSite = my myMovingControl.Bounds;
foreach(Control peer in myMovingControl.Parent.Controls) {
    Rectangle peerSite = peer.Bounds;
    if (currentSite.Contains(peerSite)) {
        //do something about the case when your moving control
        //completely covers the peer control.
    }
    if (currentSite.IntersectsWith(peerSite)) {
        //do something about the case when your moving control
        //partially covers the peer control.
    }
}

如果您不仅要检查其他控件，还需要对等控件，则需要收集您喜欢的任何集合(例如System.Collections.Generic.List<Control>)中所有有问题的控件，并以相同的方式在foreach语句中使用此集合. />

If you have to check up some other controls not only peers, you need to collect all the controls in question in any collection you prefer (such as System.Collections.Generic.List<Control>) and use this collection in the foreach statement the same way.

Any further questions?
You problems is solved.
