Dear all,
Now I create a thread to receive command from another a parent and run
GrInjectKeyboardEvent function to inject a key as command the program to do
show hide in process main loop.
In FLTK, I register the handler by
int handle(int e)
{
cout<<Fl::event_key()<<endl;
:
:
}
:
:
static void *commandHandler(void *p)
{
int com;
while(1)
{
if(mq->receive(&com))
{
}
else
{
break;
}
switch(com)
{
case 1://home
GrInjectKeyboardEvent(fl_xid(mw),'a', 0, 0, 1);
GrInjectKeyboardEvent(fl_xid(mw),'a', 0, 0, 0);
break;
case 2:
GrInjectKeyboardEvent(fl_xid(mw),'b', 0, 0, 1);
GrInjectKeyboardEvent(fl_xid(mw),'b', 0, 0, 0);
break;
}
}
}
:
:
int main()
{
:
:
Fl::add_handler(handle);
:
:
pthread_t thread;
pthread_create(&thread, NULL, commandHandler, mw);
return Fl::run();
}
However, in the handle, I always read Fl::event_key() equal to 0.
I have tried to inject ascii keys a and b but they all results 0 in handle.
I do not know why, is it my fault?
BR,
Terry
