Simulate a button click [message #37454]

Hi there!

My application shows a keyboard made of pusher-buttons. If the user clicks a button with the mouse, the keystroke gets simulated. On the other hand, if the user physically presses a key on his keyboard, the pusher has to look pushed as long as the user holds the key.

How can I do that?

PseudoPush almost does the trick, except it releases immediately. I dont know if the KeyPush() method would help, but its protected.

Ah, and I dont want to assign a hotkey to the pusher or something like that, I want to be able to make the button look pushed from anywhere in my code.

Thanks for help in advance!

Greetings,
Mirko

Inspired by this http://www.ultimatepp.org/forum/index.php?t=msg&th=6949& amp;start=0& I found a way:

The PseudoPush method is defined in Button.cpp and is actually very simple.

void Pusher::PseudoPush() {
	if(IsReadOnly() || !IsEnabled()) return;
	KeyPush();
	Sync();
	Sleep(50);
	FinishPush();
}

Now I created my own class, which offers the PseudoDown and the PseudoUp method.

class MyButton:public Button{
public:
    MyButton() {}
    ~MyButton() {}

	void PseudoDown(){
		if(IsReadOnly() || !IsEnabled()) return;
		KeyPush();
		Sync();
	}
	void PseudoUp(){
		FinishPush();
	}    
};

Works fine Smile
