Problem with trace bar in PtMTrends

Hi,

In my application I'm using PtMTrends and I'm facing a problem with it.

While I'm plotting a graph, when I place/ click the mouse pointer over the trace bar, the graph plotting slows down and 
if the pointer is moved/ released the waveform appears disturbed for a short portion but it get backs to nomral.

This causes distorted waveform and slows the down the plotting. I tried disabling the flag Pt_selectable, Pt_cosume 
events and also by enabling pt_blocked flags. The efforts were in vain.

How to overcome this?

Thanks in advance,
Lakshminarayanan.R

Re: Problem with trace bar in PtMTrends

Are you using a software mouse pointer? If you do, try switching to H/W.

RE: Problem with trace bar in PtMTrends

I'm not quite sure what you mean by switching to S/W / H/W mouse pointer! I have a PS/2 mouse connected to my target and
 I'm using devi-hirun driver for interfacing it with photon. 

Adding more input, I have a touch screen on my target and the same behavior is observed if I touch the trace bar in the 
screen. All I need is to block the interaction with this trend.

Thanks!

svga driver provides software cursor only, so mouse flickering can't be fixed.

RE: RE: RE: Problem with trace bar in PtMTrends

We do not require the mouse at all in our system since we are going to use only touch screen. In that case is there any 
solution?

Thanks Misha, the problem is now solved. I have modified the cursor to none in my display configuration file.

You shouldn't use the SVGA driver. It is only meant for testing purposes, I do not recommend it for a commercially 
shipped system. What graphics controller are you using? Maybe there is a native graphics driver for it, or you could ask
 QNX to write one for you as part of a Custom Engineering contract.
