Making a Button

[XianForce]

So, I was recently considering adding some simple GUI things to my SDL Framework. At the moment I'm simply planning some things out, but I was thinking about how I would go about making a button class.

The way I think about it, When the user clicks, I'll let some 'GUI Manager' object know, and it will, in turn, send the click to every object it is controlling.

But with buttons, every button does something different. So if I had an 'OnClick()' method, how would I make it perform different tasks?

I thought of making the button as a virtual base class, but that seems like a pain to me...

So is there a more intelligent way to do this?

There are lots of GUI systems around, there's bound to be one compatible with SDL.

Err I know that, but I'm interested in making my own >.>

Assign a listener to the button's OnClick, essentially, you just pass in what Event you want to listen for and then the name of the function.

This is exactly what I was thinking.

You may want to look into function pointers.

Yes indeed. I haven't actually used these but that could be pretty darn handy.

Yeah that's another thing I thought of, but I'm not too familiar with them, so I guess it's something to familiarize myself with them.

If you're using C++, you might NOT want to look into function pointers, and you might want to look into functoids. They're way more versatile, useful, and powerful.

I've been working with delegates in C# for too long.

I hear that. We use C# at work, and I remember going "what in the FUCK is a delegate!?!"

Well, what is it? (Resident evil quotation )

Errr... What's a functoid haha? I've never heard that term to be honest. I did a quick google search, but I keep finding functoid libraries, nothing that actually explains what it is and/or how to implement/use it.

I'm pretty sure there is a thread on the forums about them somewhere, right?

Edit: Does this help? http://accu.org/index.php/journals/561

I didn't really read it through, but it looks like it has some info... IDK though I'd say use the search bar on this forum to find the functoid thread

Edit:Edit: There is not a thread on functoids....
