[EDIT]: I found a better workaround for my own C++ code. Add one line to the main() function, like this (or use the second line with the desired style name):
int main(int argc, char *argv[])
{
qputenv("QT_STYLE_OVERRIDE","");
// qputenv("QT_STYLE_OVERRIDE","Fusion");
....
[OLD ANSWER]:
Error message:
QApplication: invalid style override passed, ignoring it.
To remove this error message:
In Qt Creator (ver 4.4.1)
Select "Projects" (wrench icon on left edge)
Under "Build & Run" (left pane)
Select "Run"
Under "Run Settings" (right pane)
Under "Run Environment"
Select "Details" (drop down list)
Scroll down to "QT_STYLE_OVERRIDE"
Click it to highlight it
Then click "Unset" button (right side)
Click "Details" to close the list
Now when you run the application you shouldn't see this error message.
