Kent, thanks for the response. This was my first thought as well, using a pixmap: QCursor cursor = QCursor(pixmap); setCursor(cursor); However, for this application, the cursor needs to be scalable so that it adjusts its size as the image being selected is zoomed in or out. Scaling the pixmap did not give the results I was looking for. However, in the interim, I have managed to find a solution thanks to someone on Stack Overflow.

See you later.

I have a pretty decent setup for development I notice that QT design studio eats resources like candy -- even if my PC can keep up with it, the fans all kick up into high gear as if I had just accepted 30 network rendering jobs. Its only in the studio though, application performance itself is fine, and in QtCreator/Designer things are fine, just that monster seems to eat and eat, I am not surprised at all to hear people with setups under and at mid-end find it completely unusable. Maybe it has something to do with latest trends showing that environments like Unity can prove new developers really will just upgrade and upgrade and not bat an eyelash, carbon emissions be darned we need more games over here! :3

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?

How can I retake a course? There seems to be no way to do this. Why not?

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.

大佬们，为什么我运行qt creator（QT版本为5.9.3）的时候，无响应，看任务管理器，内存占用率到500mb一段时间进程就退出了，也没有任何窗口显示，有大佬遇到过这种问题吗？！[image: 8c6ef968-5faf-4149-9a27-52ffbfac8f34.png] image url)

@anik Thanks for reporting this. I will take this up internally and report back to you. Just a question: Have you responded to any of the emails from the screenshot to say that you didn't want to be contacted?
