Valid cursor sizes depend on the display hardware (or the underlying window system). If hotY is negative, it is set to the pixmap().height()/2. If hotX is negative, it is set to the pixmap().width()/2. hotX and hotY define the cursor's hot spot. It is usual to give it a mask (set using QPixmap::setMask()). QCursor:: QCursor(const QPixmap & pixmap, int hotX = -1, int hotY = -1) QCursor:: QCursor(const QCursor & c)Ĭonstructs a copy of the cursor c. The effects of calling any other member function on a moved-from instance are undefined. After being moved from, the only valid operations on other are destruction and (move and copy) assignment.

It is possible that some cursors will be taken from the Xcursor theme, while others will use an internal bitmap cursor. Note: X11 does not provide appropriate cursors for all possible Qt::CursorShape values. If a cursor cannot be found using the name shown below, a standard X11 cursor will be used instead.
The table below shows the cursor name used for each Qt::CursorShape value.

On X11, Qt supports the Xcursor library, which allows for full color icon themes. Attempting to use a QCursor that was created before QGuiApplication will result in a crash. Note: It is possible to create a QCursor before QGuiApplication, but it is not useful except as a place-holder for a real QCursor created after QGuiApplication. To set or get the position of the mouse cursor use the static methods QCursor::pos() and QCursor::setPos(). 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 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.
To associate a cursor with all widgets (normally for a short period of time), use QGuiApplication::setOverrideCursor(). To associate a cursor with a widget, use QWidget::setCursor(). 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. 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.
