invalid conversionfrom‘int’to‘QWidget

This error message usually occurs when you try to pass an integer value as an argument to a function that expects a QWidget object.

For example, if you have a function that takes a QWidget object as an argument:

void myFunction(QWidget* widget);

And you try to call it with an integer argument:

int myInteger = 10;
myFunction(myInteger);

You will get the "invalid conversion from 'int' to 'QWidget'" error message.

To fix this error, you need to pass a QWidget object instead of an integer. You can create a QWidget object and pass it to the function:

QWidget* myWidget = new QWidget();
myFunction(myWidget);

Or if you have a QWidget object already, you can pass it directly:

QWidget* myWidget = ...;
myFunction(myWidget);

Make sure that the argument you are passing to the function is of the correct data type.
