Phosh.DBusScreenshot.call_pick_color

### Method

# Phosh DBusScreenshotcall_pick_color

#### Declaration [src]

    void
    phosh_dbus_screenshot_call_pick_color (
      PhoshDBusScreenshot* proxy,
      GCancellable* cancellable,
      GAsyncReadyCallback callback,
      gpointer user_data
    )

#### Description [src]

Asynchronously invokes the PickColor() D-Bus method on `proxy`. When the operation is finished, `callback` will be invoked in the thread-default main loop of the thread you are calling this method from (see g_main_context_push_thread_default()). You can then call `phosh_dbus_screenshot_call_pick_color_finish()` to get the result of the operation.

See `phosh_dbus_screenshot_call_pick_color_sync()` for the synchronous, blocking version of this method.

This method completes asynchronously. Use `phosh_dbus_screenshot_call_pick_color_finish()` inside the `GAsyncReadyCallback` to obtain the result of the operation.
