I've recently faced the same problem with Qt 5.12.2 on MacOS in my CMake project and solved it.
Also got the "undefined qt_static_plugin_qsqlite()" error.
The root cause is the wrong name used in Q_IMPORT_PLUGIN statement. After looking into the sqlite plugin library symbols, I found that it must be "QSQLiteDriverPlugin".
Hi first of all thank you for the quick answer!
I checked the window flag example and it did help me understand the hints a little better but I still have not been able get what I want.
My problem is that I want the window to be just the size of my unique toolbutton.
I've tried different combination of flag and for now the best is Qt::Dialog|Qt::CustomizeWindowHint|Qt::WindowCloseButtonHint|Qt::WindowTitleHint|Qt::WindowStaysOnTopHint
but even then the window is like twice as large as it could be...
if I remove Qt::WindowTitleHint then it becomes the right size but the title bar disapears along with the close button :p
I've done some test calling size() and frameSize() with qDebug() with the Qt::Tool and the Qt::Window flag and the results are the same on both... I've also tried calling setGeometry but obviously for the system it is already that size so it haven't done anything.
Likes like you are downscaling more than 2x. QPainter is doing bilinear
sampling when smooth scaling, and that produces bad results at 2x downscaling.
QImage::smoothScaled() uses a slower box scaling algorithm that works at even
the most aggressive downscaling.
