多个按钮一个控制变量 [英] multiple buttons one control variable

问题描述

多个按钮是否可以有一个控制变量?

我正在创建一个屏幕键盘，需要将每个用户按钮的类型定义为派生自CButton类.

我不想为要调用的DrawItem()函数的每个按钮制作单独的变量.


救命啊！ :(

Hi,

is it possible to have one control variable for multiple buttons?

i am creating an onscreen keyboard and need to make each button of a user defined type that is derived from CButton class.

i dont want to make a separate variable for each button for the DrawItem() function to be called.


Helppp!! :(

推荐答案

使用发送方对象来确定按下了哪个按钮.

在您的OnClickEvent状态下:

use the sender object to determine which button was pressed.

in your OnClickEvent state:

Button clickedOne = (Button) sender;

现在，您可以访问按钮的ID或Text属性，并执行您想做的事情

You can now access ID or Text properties of the button and do what you want to do
