Hi Greg ..
There is a concern regarding microwindow for which we have already talked
and now i have come up with more details so that we could find a solution
to it.
Let me explain you the problem in detail :-
1. It happens to be sometimes (1 in 20-30 times) that whenever i try to
wtite a text to lcd display or fill a bar the text is written horizontaly
about some percentage (say 50 %) and then again writes the same text the
remaining percentage makeing the display as if one text is written twice
half and half one over the other .
Similarly when we are dispalying the a horizontal bar the bar gers
displayed two times one over the other horizontaly.
Just to mention that this happens rarely and not always.
Is there any thing we could see into the microwindow ???
Please do share your experience and knowledge regarding this concern .
Thanks & Regards,
Misbah

Re: GrFillRect operation
You might discuss this on the list. I would think this is very likely
a hardware issue. Either writing to the display memory, or
something that the processor is doing may be causing this.
I am unaware of anything within microwindows that would cause this.
Does it only happen during text update, or the does display sometimes
just get shaky?
Regards,
Greg

Hi Greg ...
Thanks for your reply .
There is an issue i am facing with my project in which we have used
microwindow for LCD GUI. The issue is this :-
When we are displaying a string on LCD and sometimes highlighting the
string it happens to be sometimes that the displayed string becomes shaky
for a moment and then regains and becomes proper, it doesent hapens always
and only sometimes.
We need to know the probable cause of this problem and how to rectify it.
Please do share your openion/experience in this regard
Hoping for a reply soon
Thanks & Regards,
Misbah

Re: GrFillRect operation
Look at the GrFillRect implementation in srvfunc.c to see the answer to
your questions. You are looking at the client/server xfer code, below.

Hi Greg,
void
GrFillRect(GR_DRAW_ID id, GR_GC_ID gc, GR_COORD x, GR_COORD y,
GR_SIZE width, GR_SIZE height)
{
nxFillRectReq *req;
LOCK(&nxGlobalLock);
req = AllocReq(FillRect);
req->drawid = id;
req->gcid = gc;
req->x = x;
req->y = y;
req->width = width;
req->height = height;
UNLOCK(&nxGlobalLock);
}
I need to know the following implementation detail of GrFillRect() :-
1. How and which driver is called by this Gr function?
2. which low level driver / function is called accordingly ?
3. which Global data/variable is updated by this (If any) ?
Thanks & Regards,
Misbah
