So I installed qtcreator package on ubuntu 18.10.
I found out that to get the examples, I also needed the qtbase5-examples and the qtbase5-doc-html package.
But there are still no examples shown in the drop-down menu of the Welcome screen in qtcreator.
I found people with similar problem (for example for archlinux), but trying to fix the path problem does not allow the examples to show up in qtcreator.
Aynone ?
It's possible you have installed Qt Creator but not the Qt5 development libraries. Try installing the development libraries with:
Then try launching Qt Creator and see if the examples have appeared.
This may be an issue caused by not recognized qmake, i.e. QtVersion in Menu->Settings->Kits->Kits->QtVersion, showing
None
.Manually choosing it to /usr/bin/qmake and will get correct qt version.
Then examples and Kits are both OK.
