Program Configuration

Starting your program with a custom configuration looks roughly like this.

fun main() = application {
    configure {
    // settings go here
    }
    program {
        // -- one time set up code goes here
        extend {
        // -- drawing code goes here
        }
    }
}

Window size

Setting the window size is done through the width and height properties.

fun main() = application {
    configure {
        width = 640
        height = 480
    }
}

Window position

The default value for position is null for which the default behaviour is to place the window at the center of the primary display

fun main() = application {
    configure {
        position = IntVector2(100, 400)
    }
}

Fullscreen window

Setting the window size is done through the width and height properties.

fun main() = application {
    configure {
        width = 1920
        height = 1080
        fullscreen = Fullscreen.SET_DISPLAY_MODE
    }
}

or if no mode change is desired use Fullscreen.CURRENT_DISPLAY_MODE

fun main() = application {
    configure {
        fullscreen = Fullscreen.CURRENT_DISPLAY_MODE
    }
}

Window Title

fun main() = application {
    configure {
        title = "Lo and behold!"
    }
}

Window unfocus behaviour

Two window unfocus behaviours are available. In NORMAL behaviour the program continues running at full speed, in contrast the THROTTLE behaviour throttles the program to 10Hz.

fun main() = application {
    configure {
        unfocusBehaviour = UnfocusBehaviour.THROTTLE
    }
}
