I need to simulate the "drag" event in N900 to control other applications.
When my application is in background, I would like to sent drag event to the
foreground application, for example, sending a "drag from left to right" event
to control image browsing application to show the previous image. Currently I
implement it using following code.Sometimes, it worked. However, sometimes, the
drag event will not be responsed.For example, sometimes, when I simulate a drag
event to the image browser, the image switching does not happen. But I can felt
that a vibration has been triggered. It seems that the device has received a
press event (XTestFakeButtonEvent), but the motion (XTestFakeMotionEvent) is
ignored.
So does anyone know how to solved this problem? Thanks.

&event.xbutton.state);
XTestFakeButtonEvent(dpy,1,True,CurrentTime);
for(i=400;i>=300;i-=50)
{
XTestFakeMotionEvent(dpy,-1,i,
250,CurrentTime);
usleep(10000);
XSync(dpy,0);
}
usleep(10000);
XTestFakeButtonEvent(dpy,1,False,CurrentTime);
XCloseDisplay(dpy);
