The QCursor class provides a mouse cursor with an arbitrary shape.
The QCursor class provides a mouse cursor with an arbitrary shape.
This class is mainly used to create mouse cursors that are associated with particular widgets and to get and set the position of the mouse cursor.
Qt has a number of standard cursor shapes, but you can also make custom cursor shapes based on a QBitmap, a mask and a hotspot.
To associate a cursor with a widget, use QWidget::setCursor(). To associate a cursor with all widgets (normally for a short period of time), use QApplication::setOverrideCursor().
To set a cursor shape use QCursor::setShape() or use the QCursor constructor which takes the shape as argument, or you can use one of the predefined cursors defined in the Qt::CursorShape enum.
If you want to create a cursor with your own bitmap, either use the QCursor constructor which takes a bitmap and a mask or the constructor which takes a pixmap as arguments.
To set or get the position of the mouse cursor use the static methods QCursor::pos() and QCursor::setPos().
Note: It is possible to create a QCursor before QApplication, but it is not useful except as a place-holder for a real QCursor created after QApplication. Attempting to use a QCursor that was created before QApplication will result in a crash.
