# Btk
Btk is a C++ tiny retained mode GUI library based on SDL2 and nanovg.
It was written in morden C++,so it was very easy to use.
***Still developing***
## CI
|Platform| CI Status|
| --- | --- |
|Linux ||
|Windows |[](https://github.com/BusyStudent/Btk/actions/workflows/windows.yml)|
----
## Tiny example
Just create a window and add widget on here
```cpp
//Include all headers
#include
using Btk::Library;
using Btk::Window;
using Btk::Button;
struct App:public Window{
App():Window("Hello World",100,100){
//Add a button and connect signal
auto &btn = add("Close the window");
//Or
// auto *btn = new Button("Close the window");
// add(btn);
// Set the button's position and size
btn.set_rect(0,0,100,100);
//You can connect to a limbda
// btn.signal_clicked().connect([this](){
// close();
// });
//Or connect to a member fucnction
btn.signal_clicked().connect(
&App::close,
this
);
//when the object was destroyed,
//The connection will be disconnected automatically
}
};
int main(){
Library lib;//< For initialize / Quit
//Or call Init() and Quit() explicitly
App app;
app.mainloop();
}
```

## Features
- Almost no macro,the signal system was written in template
- The Library will use the font in os
- UTF-8 support

## TODO List
- [ ] Add more useful widgets
- [ ] MessageLoop need to be refactored
- [ ] Rewrite ImageView By OpenGL to implement AntiAlias
- [ ] Add CMake
- [ ] Add GLX and WGL OpenGL Adapter
- [ ] Add API to get system color and system metrics
- [ ] Widget Interface need to be refactored
- [ ] String Interface need to be refactored to fit STL
- [ ] Font need to be refactored,Current font backend is not good enough(need hb support)
- [ ] Renderer backend DPI support
