      • Monitor Information

      monitor feature is used to enable monitor query capability. It is suitable for initial window positioning, multi-screen adaptation, reading work area size, adjusting custom logic by monitor DPI, and similar tasks.

      [dependencies]
flor = { version = "0.1.0", features = ["direct2d", "monitor"] }

      Basic Usage

      Monitor entry is in platform layer. When using import MonitorApi trait.

      use flor::base::platform::MonitorApi;
use flor::platform::Monitor;

let monitors = Monitor::enumerate_monitors()?;

for monitor in monitors {
    println!(
        "{} primary={} scale={} dpi=({}, {})",
        monitor.name(),
        monitor.is_primary(),
        monitor.scale_factor(),
        monitor.dpi_x(),
        monitor.dpi_y(),
    );
}

      Query Entry

      MethodPurpose
      Monitor::enumerate_monitors()Enumerate all monitors.
      Monitor::monitor_from_point(x, y)Query monitor at a given screen coordinate.
      Monitor::monitor_from_window_id(window_id)Query monitor where window is located.
      monitor.rect()Monitor complete area.
      monitor.work_area()Available work area, usually will exclude taskbar and other system areas.
      monitor.scale_factor()Scale factor, usually derived from DPI.
      monitor.dpi_x() / monitor.dpi_y()Current monitor DPI.

      If just want layout units to update with window DPI, usually don't need to manually query monitor; see High DPI.
