Program windows

An OPENRNDR program can listen to events generated by its window.

Window properties

The window title can be set and read using the title property.

fun main() = application {
    configure {
        title = "Lo and behold!"
    }
    
    program {
        println(window.title)
    }
}

Window position

The window position can be read and set using the position property.

fun main() = application {
    configure {
        position = IntVector2(30, 30)
    }
}

Window events

Window move event

This event is generated when the window was moved.

fun main() = application {
    program {
        window.moved.listen {
            println("the window was moved")
        }
    }
}

Window size event

This event is generated when the window was sized.

fun main() = application {
    program {
        window.sized.listen {
            println("the window was sized")
        }
    }
}

Window focus event

This event is generated when the program window gains focus.

fun main() = application {
    program {
        window.focused.listen {
            println("the window has gained focus")
        }
    }
}

Window unfocus event

This event is generated when the program window loses focus.

fun main() = application {
    program {
        window.unfocused.listen {
            println("the window has lost its focus")
        }
    }
}
