X11 Mouse Movement Event

When creating a Window in XLib - What are the masks I provide to the `SetWindowAttributes.event_mask` member? - What do I have to pass to the 11th paramater of `XCreateWindow()` - What are the Events I am looking for in the main message loop (Where I use `XNextEvent(lDisplay, &xEvent);`? - Since X behaves differently than Microsoft's Win32 API, how do I determine if the mouse is over my window or a window in my "Application" and not over the desktop? I have looked for a similar post. If there is already one out there please point me in the right direction. Update For those who want the easy answer to parts 1-3: 1. ``` xAttributes.event_mask = ExposureMask | KeyPressMask | ButtonPress | StructureNotifyMask | ButtonReleaseMask | KeyReleaseMask | EnterWindowMask | LeaveWindowMask | PointerMotionMask | Button1MotionMask | VisibilityChangeMask | ColormapChangeMask; ``` 2. `unsigned long valuemask = CWEventMask | CWBackPixel | CWBorderPixel | CWCursor;` ``` switch (xEvent.type) { case MapNotify: break; case Expose: // If this is not the last expose event break if (xEvent.xexpose.count != 0) break; else break; case ConfigureNotify: break; case VisibilityNotify: break; case DestroyNotify: break; case ButtonPress: case ButtonRelease: case EnterNotify: case MotionNotify: case LeaveNotify: if(_mouseHandler) _mouseHandler->HandleInput(lDisplay, &xEvent); break; case KeyPress: case KeyRelease: if(_keyboardHandler) _keyboardHandler->HandleInput(lDisplay, &xEvent); break; default: if(_keyboardHandler) _keyboardHandler->HandleInput(lDisplay, &xEvent); break; } ```
