PdoxWin: How to detect mouse button status in MouseDown method....

[Zafar Ullah Choudhry]

I am trying to achieve a repeat on a mouse button. More specificly, I have
written MouseRightDown method for a button and I want to stay in this method
as long as right button on the mouse remains depressed. My problem is that
I don't know how to detect the state of the mouse button while in MouseRight
Down method. I want to use a loop in MouseRight method, that should break when
the right mouse button is lifted up.

Thanks.
Zafar.

So how about setting a variable in MouseRightUp and then in your
MouseRightDown loop check to see if that variable is set or not?

Because the MouseRightUp method won't execute while the loop in
MouseRightDown is executing.

Here's an ugly way to do it. Perhaps with some additonal thought it can be
made better...

In the MouseRightDown method:
InitializeLoop()
setTimer(X) ; tune X for the best performance

In the MouseRightUp method:
stopTimer()
CleanUpAfterLoop()

In the Timer method, put the code from the body of the loop, with no loop
control code around it-- the timer will take care of invoking it over and over
until the mouse button is released.
