如何获得一个Contextmenu右键单击Windows应用程序中的图片框。必须显示所有图片框的相同上下文菜单。

How can I get a Contextmenu on Right click the picture box in windows application.The same contextmenu has to display for all the picture boxes.

推荐答案

试试这个.. try this.. pictureBox1.ContextMenustrip=contextMenuStrip1;

这不是这很难，但很容易忘记。 例如，假设您有一个图片框，并且您已经在其上绘制了一些内容，并希望用户能够在选择某个内容时拥有一个上下文菜单，而不是选择。您可以在选择/未选择内容时为上下文菜单指定图片框。或者你可以在右键单击显示它们菜单。 我在这里显示第二件事因为我发现维护时不易出错，只是我个人的选择。 在任何一种情况下，你都要创建一个上下文菜单对象，填写它，创建处理程序等。 This isn't that hard, but easy to forget. For example, lets say you have a picture box, and you have drawn things on it and want the user to be able to have a context menu for when a thing is selected and a different one when not selected. You could assign the picture box the context menu as things are selected / not selected. Or you could do it on the right click show them menu. I'm showing that second thing here because I find it less error prone when maintaining, just my personal choice. In either case you'd create a context menu object, fill it in, create the handlers, etc. if (e.Button == MouseButtons.Right) { mPointWhenClicked = new Point(e.X, e.Y); if (mObjectAlreadySelectedInImage != null) { contextMenuWhenSelected.Show(pictureBox1, e.X, e.Y); } else { contextMenuWhenNotSelected.Show(pictureBox1, e.X, e.Y); } }
