如何使用gdk_device_get_position（）？ [英] How to use gdk_device_get_position()?

问题描述

我试图在Gdk中获取指针在屏幕上的位置，并找到 gdk_display_get_pointer（），它可以正常工作，但已标记为已弃用，并引用了 gdk_device_get_position（）现在。

I am trying to get the pointer position on screen in Gdk and found gdk_display_get_pointer(), which works fine, but it's marked as deprecated and refers to gdk_device_get_position() now.

但是如何使用此功能？我找不到 GdkDevice ，因为没有工厂，也没有构造函数。

But how do I use this function? I cannot get a GdkDevice, since there is no factory, nor is there a constructor.

推荐答案

使用Gdk.DeviceManager。

use Gdk.DeviceManager.

.....
.....
GdkDisplay *display = gdk_display_get_default ();
GdkDeviceManager *device_manager = gdk_display_get_device_manager (display);
GdkDevice *device = gdk_device_manager_get_client_pointer (device_manager);

// do whatever with Gdk.Device, i.e:
int x, y;
gdk_device_get_position (device, NULL, &x, &y);
printf ("x= %d, y=%d", x,y);
