在Linux下,获取其他应用程序文本框光标位置有多种方法,其中比较常用的是使用X Window System的X11库来获取。
以下是使用X11库获取其他应用程序文本框光标位置的代码示例:
```
#include <X11/Xlib.h>
#include <X11/Xutil.h>
Display* display = XOpenDisplay(NULL);
Window focusWindow;
int revertTo;
XGetInputFocus(display, &focusWindow, &revertTo);
XTextProperty prop;
XGetWMName(display, focusWindow, &prop);
XTextProperty xtp;
XGetWMName(display, focusWindow, &xtp);
char **list;
int count;
if (XmbTextPropertyToTextList(display, &xtp, &list, &count) == Success && count > 0) {
XFreeStringList(list);
}
XWindowAttributes attrs;
XGetWindowAttributes(display, focusWindow, &attrs);
XEvent event;
XGenericEventCookie* cookie = &event.xcookie;
bool sent = false;
memset(&event, 0, sizeof(event));
event.type = GenericEvent;
event.xcookie.display = display;
event.xcookie.window = focusWindow;
event.xcookie.type = XdndPosition;
event.xcookie.send_event = true;
event.xcookie.private_data = (Atom) cursorPosition;
sent = XSendEvent(display, focusWindow, False, 0, &event) > 0;
if (sent && cookie->type == GenericEvent && cookie->extension == XdndNoti- cation) {
XdndPositionRe- ply* reply = (XdndPositionReply*)cookie->data;
int xPos = reply->x_root;
int yPos = reply->y_root;
printf("Cursor position: (%d, %d)\n", xPos, yPos);
XFree(reply);
}
```
