You can use that to determine which button wasclicked.

So you need to know how todetermine which control has been clicked. I''m not sure I know how to help you. You could possibly get the x,ycoordinates of the mouse click and then loop through the controls onyour form and find out if that point is withing the area taken up byyour control. Perhaps someone else will be able to suggest a better approach. Sorry 这篇关于应该有一些一般的鼠标事件的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
