I want to grab the mouse totaly. I mean with grabing, that all low level
Mouse event should be send to my
application. in linux I can grab the pointer on X server. in windows I
should create a Hook.
is there any way to handle this in SWT?
sorry the fellowing may be more Windows specific!
I have create a small java with JNI. the JNI DLL register a hook like the
following:
thisInstance1 = LoadLibrary((LPCTSTR) "hockdll.dll");
hkMouse1 = (HOOKPROC)GetProcAddress(thisInstance1, "MouseHookProc");
printf("Hello2 world! %p %p\n", thisInstance1, hkMouse1);
g_hMouseHook = SetWindowsHookEx(WH_MOUSE_LL, hkMouse1, thisInstance1,NULL);
after running my java application I got a correct g_hMouseHook,
thisInstance1 and hkMouse1 . and also mouse stopped moving,
but my Hook function never got called. and after a few second the mouse
return to its normal execution, because windows wait.

Control.setCapture() will capture all events sends my the system to our
appliation to be forwarded to
the control capture the mouse events. what I want is a global capture, I
want to capture all mouse events from system to be send to my application
that mean no other applicaton on the desktop should receive mouse events
when I register it.

Well, just one advice: don't do this. :-)
And I don't belive that you can do this using only SWT.
