QWidgetsetCursor

QWidgetsetCursor is a method in the Qt framework that allows developers to change the mouse cursor displayed when it hovers over a specific QWidget. This method is part of the QWidget class and is inherited by all its subclasses.

To use QWidgetsetCursor, you need to provide a QCursor object as an argument. QCursor objects represent different cursor shapes, such as a standard arrow, a hand, a crosshair, or an hourglass. Qt provides a set of predefined cursor shapes that can be accessed through the Qt::CursorShape enumeration. For example, you can set the cursor to a pointing hand by passing Qt::PointingHandCursor to the setCursor method.

The setCursor method can be called at any time to change the cursor. The change will take effect immediately when the mouse pointer enters the widget's area. If you want to restore the cursor to its default behavior, you can call setCursor with Qt::ArrowCursor or by calling unsetCursor.

This functionality is useful for providing visual feedback to the user about the interactive capabilities of a widget. For instance, a button might change its cursor to a pointing hand to indicate that it can be clicked, while a resizable border might display a double-headed arrow cursor. Proper use of setCursor can enhance the user experience by making the application's interface more intuitive and responsive.
