It's hilarious, when you go to Akismet.com their front page is flaunting that their spam filter is accurate 99.99% of the time. Wow, we must all be the 0.01%

Try another pc, maybe the graphics card driver has a problem with it.

I have a desktop app which runs on linux. I have my own laptop which runs on windows. I downloaded squish for windows on my own computer. I downloaded vncserver(tigervnc) on desktop app. Hoping to reach to my desktop app via using VNC on squish IDE and record scenarios. On my computer I created test suite, selected VNC as GUI toolkit. I did my configuration as needed under "Server Settings > Manage AUTs > Attacable AUTs". After that created test case and hit record button but got this error lines. "Warning: AUT '__squish__vncaut' (with AUT path '') does not exist FATAL Starting application Application '__squish__vncaut' could not be started. Squish couldn't start the AUT because the program doesn't exist. Make sure the AUT is really built and was not removed. Also make sure that the path to the AUT is correct in the settings. END End of test Giving up after error" I'm sure my vnc server runs on my desktop app. In https://forum.qt.io/topic/155170 i get that we might have similar issue. Should i download squish for qt? Or should i just download squishserver on my desktop app and expect it to be resolved? If i should download squish server on my desktop where can I the server package without downloading whole installation package on the application?

Hey @Carditus, We have released our Certification Testing Platform with the first test. Read more here: https://www.qt.io/qt-certifications.

Posts about the capabilities of QTimer come up every few months. Timer resolution is dependent upon the underlying OS capabilities, and in a time-sharing OS, there will be jitter when small timer intervals are used. The timers should only be used for functions that facilitate smooth user interaction, not critical events with short intervals. I hesitate to mention solid interval limits because it is system dependent, but I dont do anything less than 50ms when I do timers. Within the confines of a time-sharing OS your approach with threads and busy-waits is more appropriate. You can insert a "small" msleep in the loop to destress the cpu, but again, you're competing with other tasks so you are at the mercy of the cpu scheduler. look into realtime scheduler class as that may help, but understand that class requires you to execute as root, and you can starve other tasks by misusing it.

@JonB said in Hitchhiker's Visual Guide to the Qt Forum: @RokeJulianLockhart I am indeed a moderator, so that may make a difference. I do not know what "Ask as question" does! :) It turns a "normal post" to a question that can be marked as solved. This can be useful for example when an old imported topic still gets activity but was marked solved the old way.
