Title: Get Key ID When Key Is Pressed? (C++)
Post by: Ajm113 on February 21, 2009, 11:34:07 pm

Hello, SFML community!

Ok, I decided to get my game going on for Linux and Mac from Win32, but I needed a good API that was portable easy and this API looks about right! :wink:


Ok, I got a bool array of 256. What I want to do is so the ID number of a key was pressed like A was pressed row 1 of that array will be set to true and when A is released row 1 is set to false.

How can I do that? Like Wparam and Win32 examples show sometimes.

You don't need to do so, sf::Input already keeps track of the keys state.

Alright, I'll play around with it. Its wired its like IntelliSense isn't picking up on your API that well. It seemed to work a while ago now it's Intellisense isn't showing a drop down box .

Any ways I have a couple more questions.

Whats a alternative of timeGetTime from windows in your API? I need it for my performance handler.

How can I set a window's state? I.E Maximize, Minimize, etc?

And how can I get the user's screen x,y cords?

Thank you, Andrew.

Maybe you should just read the documentation and tutorials instead of relying on Intellisense? :wink:

Ok, I got most of what I want converted. How can I display a Messagebox? I looked through your docs. It seems you guys cover everything except that.

There's currently nothing for message boxes in SFML.

Really, why? You guys cover everything, except for a message box?? Can you suggest what to do?

Well, SFML is not a windowing API such as Qt or wxWidgets. All it has to do is providing a window to draw into. Message boxes are not directly related to what you can expect from SFML.

However, you can draw one inside your window using a rectangular shape and a graphical string :)

Well whats Linux's Messagebox command?

I thought something like this feature would be no problem to add. If your API can run on different Operating Systems.

It might not be hard to implement, but it's outside of SFML's scope. SFML doesn't provide any GUI elements, and (probably) never will. If you want native message boxes, use a UI toolkit like GTK, QT, or wxWidgets. Like someone else said above, you could also write your own SFML-based message box, with a rectangle or string. Or you could take a look at the wiki, there's the starts of a GUI framework for SFML there. It's called IMGUI.

I mite go with GTK, I'll just finish what I have going on here and then see by the weekend on getting linux and then compiling the game on it.
