Hello Greg, hello everybody,
it seems, that my mouse/touch-twin works, at least with the famous ntetris.
But one problem remains unsolved:
I could not switch between visible cursor and invisible cursor. Neither with
function GrInjectPointerEvent(GR_COORD x, GR_COORD y, int button, int visible)
nor directly with GrShowCursor/&scrdev);/GrHideCursor(&scrdev);. I have
implemented it in my two function GsCheckMouseEvent and GsCheckTouchEvent. Once
the cursor disappears, and it even disappears when using first the mouse
instead of the touch, it stays disappeared (on startup you can see the mouse
pointer). If I let the functions without calling the above mentioned functions,
there is no problem at all and I can work both the touchscreen and the mouse
with the mousepointer beeing the whole time showing.
My code is
/*
* Update mouse status and issue events on it if necessary.
* This function doesn't block, but is normally only called when
* there is known to be some data waiting to be read from the mouse.
*/
GR_BOOL GsCheckMouseEvent(void)
{
GR_COORD rootx; /* latest mouse x position */
GR_COORD rooty; /* latest mouse y position */
int newbuttons; /* latest buttons */
int mousestatus; /* latest mouse status */
/* Read the latest mouse status: */
mousestatus = GdReadMouse(&rootx, &rooty, &newbuttons);
if(mousestatus < 0) {
GsError(GR_ERROR_MOUSE_ERROR, 0);
return FALSE;
} else if(mousestatus) { /* Deliver events as appropriate: */
GdHideCursor(&scrdev);
GdShowCursor(&scrdev);
GsHandleMouseStatus(rootx, rooty, newbuttons);
/* possibly reset portrait mode based on mouse position*/
if (autoportrait)
GsSetPortraitModeFromXY(rootx, rooty);
return TRUE;
}
return FALSE;
}
/*
* Update touch status and issue events on it if necessary.
* This function doesn't block, but is normally only called when
* there is known to be some data waiting to be read from the touch.
*/
GR_BOOL GsCheckTouchEvent(void)
{
GR_COORD rootx; /* latest touch x position */
GR_COORD rooty; /* latest touch y position */
int newbuttons; /* latest buttons */
int touchstatus; /* latest touch status */
/* Read the latest touch status: */
touchstatus = GdReadTouch(&rootx, &rooty, &newbuttons);
if(touchstatus < 0) {
GsError(GR_ERROR_MOUSE_ERROR, 0);
return FALSE;
} else if(touchstatus) { /* Deliver events as appropriate: */
GdHideCursor(&scrdev);
GsHandleMouseStatus(rootx, rooty, newbuttons);
/* possibly reset portrait mode based on touch position*/
if (autoportrait)
GsSetPortraitModeFromXY(rootx, rooty);
return TRUE;
}
return FALSE;
}
and it does also not works if I implement it in devmouse.c in functions
GdReadMouse and GdReadTouch.Why is that? Any idea?
Mit freundlichen Grüßen/Best Regards
