How to stop the flashing/blinking keyboard cursor?

"Keyboard cursor" is an unusual term. Do you mean the cursor at the insertion point in any entry widget on any form or UI? If so, that's pretty much standard in all applications, on Linux or Windows. So I'd be surprised if that's what  you mean. If you mean something else, please explain what. If you mean this, please explain why you want to change it for virtuoso when everything else in the world seems to work that way too...

Andrew.

If I would write only "cursor" everyone would think that I mean the (mouse-) pointer. wikipedia call that thing what I mean a "text cursor".
You are right, that that blinking is standard. But on Windows one can turn that behavior of by reducing the flashing/blinking-rate to zero (moving the bar to the left) in the keyboard property window.
I run Virtuoso on a Windows-Machine by using MobaXterm and connecting to a linux-server. That means, that the windows-properties have no effect on Virtuoso. That is my problem.
Do you have an idea if there is a way to change that cursor-blinking?

On my Linux machine, I can do this with:

/usr/bin/qtconfig-qt4

and then go to the Interface tab and change the Cursor Flash Time setting. Because Virtuoso is a Qt-based UI, this also affects Virtuoso.

Wonderful! You gave me the right keyword: qtconfig. That led me to the site

Thank you very much Andrew!

Hi Andrew,

4 years ago your answer helped me to find the solution. I found the site
http://www.jurta.org/en/prog/noblink
In the paragraph "Qt applications in KDE" I found the hint to add
[Qt]
cursorFlashTime=0
in
~/.config/Trolltech.conf
and from then on, the cursors didn’t blink anymore.

But now we want to use ICADVM instead of ICADV and the cursors are blinking again!

Does ICADVM use Qt5 whereas ICADV does use Qt4? Is it possible, that this is the reason?

The site advises to use this utility
https://github.com/igogo/qt5noblink
for Qt5 apps. But my knowledge in using linux is to bad. I don’t understand how to use this utility with virtuoso. Step 1 and 2 are clear. But I don’t understand what I have to do with the command in step 3.

Do you have an idea, how I can stop the cursor blinking in ICADVM?

Thank you!

Hi Magistus,

I'm not sure I should encourage you to do this, but here goes anyway...

ICADVM181 and IC618 are based on Qt5, as you suggested.

If you've built the shared library, then you can just (if using bash) do:

LD_PRELOAD=/path/to/qt5noblink.so virtuoso

If you're using csh, rather than setting LD_PRELOAD generally using setenv, I'd suggest you create a wrapper script called "virtuosonobl" which does:

#!/bin/sh
LD_PRELOAD=/path/to/qt5noblink-master/qt5noblink.so virtuoso "$@"

Then you can just run "virtuosonobl" provided it's in your path.

Regards,

Andrew.
