Constructs a cursor with the default arrow shape.
Constructs a cursor with the specified shape.
See Qt::CursorShape for a list of shapes.
See also setShape().
Constructs a custom bitmap cursor.
bitmap and mask make up the bitmap. hotX and hotY define the cursor's hot spot.
If hotX is negative, it is set to the bitmap().width()/2. If hotY is negative, it is set to the bitmap().height()/2.
The cursor bitmap (B) and mask (M) bits are combined like this:
Use the global Qt color Qt::color0 to draw 0-pixels and Qt::color1 to draw 1-pixels in the bitmaps.
Valid cursor sizes depend on the display hardware (or the underlying window system). We recommend using 32 x 32 cursors, because this size is supported on all platforms. Some platforms also support 16 x 16, 48 x 48, and 64 x 64 cursors.
Note: On Windows CE, the cursor size is fixed. If the pixmap is bigger than the system size, it will be scaled.
See also QBitmap::QBitmap() and QBitmap::setMask().
Constructs a custom pixmap cursor.
pixmap is the image. It is usual to give it a mask (set using QPixmap::setMask()). hotX and hotY define the cursor's hot spot.
If hotX is negative, it is set to the pixmap().width()/2. If hotY is negative, it is set to the pixmap().height()/2.

Constructs a copy of the cursor c.
Constructs a Qt cursor from the given Windows cursor.
Warning: This function is only available on Windows.
See also handle().
Constructs a Qt cursor from the given handle.
Warning: This function is only available on X11.
See also handle().
Destroys the cursor.
Returns the cursor bitmap, or 0 if it is one of the standard cursors.
Returns a platform-specific cursor handle. The HCURSOR_or_HANDLE type is HCURSOR on Windows and Qt::HANDLE on X11 and Mac OS X. On Qt for Embedded Linux it is an integer.
Warning: Using the value returned by this function is not portable.
Returns the cursor hot spot, or (0, 0) if it is one of the standard cursors.
Returns the cursor bitmap mask, or 0 if it is one of the standard cursors.
Returns the cursor pixmap. This is only valid if the cursor is a pixmap cursor.
Returns the position of the cursor (hot spot) in global screen coordinates.
You can call QWidget::mapFromGlobal() to translate it to widget coordinates.
See also setPos(), QWidget::mapFromGlobal(), and QWidget::mapToGlobal().
Moves the cursor (hot spot) to the global screen position (x, y).
You can call QWidget::mapToGlobal() to translate widget coordinates to global screen coordinates.
See also pos(), QWidget::mapFromGlobal(), and QWidget::mapToGlobal().
This is an overloaded member function, provided for convenience.
Moves the cursor (hot spot) to the global screen position at point p.
Sets the cursor to the shape identified by shape.
See Qt::CursorShape for the list of cursor shapes.
See also shape().
Returns the cursor shape identifier. The return value is one of the Qt::CursorShape enum values (cast to an int).
See also setShape().
Returns the cursor as a QVariant.
Assigns c to this cursor and returns a reference to this cursor.
Writes the cursor to the stream.
See also Format of the QDataStream operators.
Reads the cursor from the stream.
See also Format of the QDataStream operators.
