Unknown module QQuickWidget

Ashutosh_Sachdeva

Hi,

I'm using QT 5.13.1 and while using QTQuickWidgets imy project is throwing the error

":-1: error: Unknown module(s) in QT: qquickwidget QQuickWidget"

i have updated Qt as well tried with giving the path but still the error is there.

jsulm

QT += quickwidgets

in your pro file as described here https://doc.qt.io/qt-5/qquickwidget.html ?

Ashutosh_Sachdeva

@jsulm yes i have included that in .pro

ok, before we go any further, take a look at this example:
https://doc.qt.io/qt-5/qtquick-quickwidgets-quickwidget-example.html

It should be part of your Qt /QtCreator package. See if that compiles.

quickwidgets No preceding q and an s at the end. You need to get this string exactly right in your .pro file. And remove QQuickWidget from there, it's not the module name.

But wrongly, as @sierdzio explained...

@sierdzio tried but still facing same issue

jsulm

@Ashutosh_Sachdeva Please show your pro file.
And also you have to do complete rebuild after changing pro file: delete build directory, run qmake and build...

still not what @sierdzio said

also, you didn't check the example I linked, or you could have simply copy and pasted it from there
