Header file not found

ofmrew

In the latest version of QtCreator, I used add new to create a class, both header and sources files were created. I promoted a Widget in Design to the new class, renamed and checked autoFill Background. Then when I started to add
ui->canvas->setBackgroundRole(QPalette::Base);
I see the message canvas.h not found.

An aside, one note also about the editor: I found using ui. and having the editor change it to ui-> very helpful, but that has been removed.

How do I get a header file, that was created by Qt, found?

I think it's a regression in Qt Creator 8. Please open a bug report at https://bugreports.qt.io/

Thank you.

@ofmrew I forgot to ass additional information:
QT += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

CONFIG += c++17

You can make your code fail to compile if it uses deprecated APIs.

In order to do so, uncomment the following line.

#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 # disables all the APIs deprecated before Qt 6.0.0

SOURCES +=
main.cpp
mainwindow.cpp
mycanas.cpp

HEADERS +=
mainwindow.h
mycanas.h

FORMS +=
mainwindow.ui

Default rules for deployment.

qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

@ofmrew said in Header file not found:

I see the message canvas.h not found.

@mpergand I see the problem, it should be canvas and not canas! The old eyes have see too many mango seasons. Thanks.
