lwjgl-integration

An example showing how to integrate Compose with LWJGL

Note that:

• the integration is very experimental and can be unstable
• not all features are implemented
• not all features are currently supported (Accessibility, Input Methods)
• to pass some event information it is needed to pass it via AWT events (java.awt.KeyEvent and java.awt.MouseEvent). In the future versions of Compose we plan to get rid of the need of AWT events.

Problems

Cursor In TextField

This is easy, you need to provide androidx.compose.ui.platform.WindowInfo in CompositionLocal

For example:

CompositionLocalProvider(
    LocalWindowInfo provides object : WindowInfo {  override val isWindowFocused: Boolean = true }
) {
    // Your App
}

Popup

Since Compose still use some awt events (#1736), you can provide a fake contaniner.

val awtContainer = object : Container() {}

// call it when your custom compose app changes winodw position
fun onWindowUpdate(x: Int, y: Int, width: Int, height: Int) { 
    awtContainer.setBounds(x, y, width, height)
}

CompositionLocalProvider(                                                                                 
    LocalLayerContainer provides awtContainer                   
) {                                                                             
    // Your App                                                                        
}
