I have installed qt 6.7.2 on macos (from installer), and am now trying out the simple tutorial for TextFinder. I have completed the instructions upto step-8, ie added the widgets in the Designer. Now in step-9, when I am trying to add goto-Slot in FindButton, I am getting the error: “No documents matching “ui_textfinder.h” could be found. Rebuilding the project might help.”

This file (ui_textfinder.h) does not exist, instead I have a file named “textfinder.h”. The instructions also say that the slot will be added in the file “textfinder.h”. I tried making a symbolic link ui_textfinder.h linked to the existing textfinder.h, but that does not help – I am still getting the same error. I also tried rescanning the project, that is also not helping, even though now the ui_textfinder.h file is seen in the file system tab in the QtCreator.

How do I fix this problem? The error says I might rebuild the project, but the files are not yet fully created, so is that going to help?

(Note: this error does not come up when I install qt with homebrew. It shows up only when I install with qt-installer – qt-online-installer-macOS-x64-4.8.0.dmg, downloaded from qt website.)

I see that another person had raised a similar complaint. But the answer given there is not clear to me. Also, that is an old question, so that might have referred to some other version of qt.
