Mouse Location after Click

[KyletheProgrammer]

I'm relatively new to handling mouse events and can't get it to work.

How would you get the mouse location only after pressing the left mouse button for instance? I can just get the location with:

POINT pt;
GetCursorPos(&pt);

But I don't know how to tell it to wait for a click first. Thanks for any help.

I think you should first get whether the mouse has clicked and after the position, for doing it with Win API take a look at this example: http://msdn.microsoft.com/en-us/library/ms685035(VS.85).aspx

Thanks for the advice, I just don't understand anything about API. I really don't understand what any of those values mean in the MSDN website and why things look like that.

I need to figure out how to code:

wait for a mouse click.
find location. // I can do that already.

The (x,y) position is part of the information that comes with the mouse event.

Are you doing this in a GUI or Console program?

I'm doing it in a GUI. (fltk)

I already have something like this:

POINT pt;

if(GetCursorPos(&pt)!=0)
{
x=pt.x;
y=pt.y;
}

This tells me the location but it does it instantly at the beginning. I need to wait for a mouse click first, but I don't know how to do that.

The FLTK documentation takes a little getting used to.

Every time you do something, it generates an event and sends it to the associated widget via the handle() virtual function. Here is a little example that displays how to override it and trap events.
