超过事件点击 [英] Making more than event click

问题描述

拜托，我想知道如何在一个按钮上制作两个事件，如：当我第一次点击按钮显示图像时仍处于调试模式第二次点击

显示另一个image我可以使用哪些代码？

please, I want to know how to make two events on one button like : when i first click on the button display an image and still in the debugging mode the second time i click
display another image what code can i use?

推荐答案

在类级创建一个整数变量，将其设置为1.

每次单击按钮，检查变量的值，如果它大于图​​像数，则将其设置回1.

显示该图像编号。

增加变量下一次。

Create a integer variable at class level, set it to one.
Every time you click the button, check the value of the variable and if it is greater than the number of images, set it back to 1.
Show that image number.
Increment the variable for next time.
