C++ Win32 How to Create a “toggle” Pushbutton

问题

I was originally thinking this would be extremely easy to do. Google searches returned results for everything but this.

I am trying to have a normal button that I can click, and it stays down, click again, and it rises back up.

I found one function that did what I wanted, but only worked if the button retained focus, click anywhere else and it rises again.

Button_SetState(GetDlgItem(hwnd, IDC_BTN_SLEEPCLICK), TRUE);

Is there any real way to do this? Or am I gonna need to do this kind of thing by hand?

Thanks.

回答1:

Create a check box, then set the "push like" property for that check box to true.

回答2:

You want a checkbox with BS_PUSHLIKE style. To toggle it programmatically, use Button_SetCheck

回答3:

The "staying down" and "rising back up" are a matter of how you draw the button.

You could create your own button class by using the Paint and Redraw methods.
