TGUI: a c++ GUI for SFML (with Form Builder)

[texus]

if I create a TGUI window, I can use it in the same way I would use a SFML one?

Yes, my window is just a wrapper around sf::RenderWindow, so you can still use all its functions.
But you will still have to link with sfml, linking to only tgui isn't enough.

What if I want to use stuff such as SFML/Network.hpp, or even OpenGL?

For networking or audio there is no problem at all. You can use it in exactly the same way as when you aren"t using TGUI.
I am not sure about OpenGL. I never tested it so I can't tell you if it would work.
If you use it correctly it will probably work but I will test it in the future to be sure.

Is it possible to change the textures/colors if I don't like the default ones?

Absolutely. The colors can be changed by calling a function like setTextColor, setBackgroundColor or changeColors (look at the example code where the combo box is created).
Changing the images is simply a matter of passing a different pathname to the load function.
Just copy the Black folder, rename the new one to what you want, edit the images in it and pass the new pathname to the load function.
It might be a little hard to understand the image filenames and the info.txt file in the beginning, but if you have any questions I will be here to answer them.

Thank you very much! That covered everything

I got good news: the TextBox is now working.
The only thing that is still missing is word wrap, but that will be for later.

Example code on how to use the TextBox:

tgui::TextBox* textBox = window.addTextBox();
textBox->load(280, 160, 30); // Width, height, text size, (optional scrollbar pathname)
textBox->setPosition(440, 400); // Set the position of the TextBox
textBox->setBorders(4, 4, 4, 4); // Add a border of 4 pixels on every side
textBox->setText("This is the text that will be displayed inside the TextBox.");
   
// To change the colors, simply call changeColors (the function has more optional parameters)
textBox->changeColors(sf::Color::White, sf::Color::Black); // background color, text color

The GUI looks nice and the code is easy to understand.

I tested SFGUI and TGUI.
On my Windows 7 PC (30% lesser CPU usage then SFGUI? -> Without the sf::sleep(sf::milliseconds(100)); in TGUI Loop).

Why this? is SFGUI to complex? Or because of RenderWindow slower? Or just my imagination?

[texus]

I have no idea why this would be, but I think it will depend on the situation. I doubt that sfgui would be slower than tgui.

On the contrary. You see more CPU usage with SFGUI because indeed more CPU time is being used because we optimized the library to the point where we offload certain portions of the processing from the GPU to the CPU and therefore the CPU and GPU times are equal. Search for my many other posts and you will see my statements about how SFML is bottlenecked by GPU processing power and bus transfer bandwidth. We eliminate this in SFGUI and so the application will pump out more frames per second but also make more use of the CPU which is expected. You can test this by observing the framerate of your test benchmark for both libraries.

It might be possible that at a lower widget count the overhead that SFGUI is associated with won't make it worth using, however it is amortized at higher, more typical widget counts which is what we optimized for.

If this feature doesn't already exist, it would be nice to have a picture button. If you add that, I will totally use this GUI.

[texus]

My Picture class can give a callback when clicking on it, if that is what you mean.

[Tresky]

So, in other words, the picture class can be used as a button?

[texus]

Yes.

The difference with the Button class is that a button can change its image on mouse hover or mouse down, while the Picture is just one image that can (if you want it to) send a callback on mouse click.
A Button is also able to send a callback when it is focused and you would press the space bar or the return key.

[Tresky]

Sweet. This system looks very promising. You've got my vote.

Hi. I did a little looking at the documentation that you have and I couldn't really devise a way to make the text boxes lose focus when you click out of them. Am I missing something? Aside from that I've been enjoying using your library.

Thanks.

[texus]

The text box (and any other object) will only lose focus when focusing another object (by clicking on them or by using the tab key).
I will look into it, if it is easy to solve (which it probably is) then I will fix it within the next few days.

Hi texus,

i played around TGUI a bit and I like it very much.

I created some control skins and I plan to write
simple game development articles using it.

Keep up the good work.

[texus]

I am happy that you like it.
