Implicitly Shared Classes
These classes are normally-heavy classes which in Qt have been
optimized by the use of reference counter and common data so they can
be passed around.
The only important effect is that the classes listed here can
be passed around as arguments, even though they may seem heavyweight.
Classes:
- QBitArray
(Array of bits)
- QBitmap
(Monochrome (1 bit depth) pixmaps)
- QBrush
(Defines the fill pattern of shapes drawn by a QPainter)
- QCString
(Abstraction of the classic C zero-terminated char array (char*))
- QCursor
(Mouse cursor with an arbitrary shape)
- QIconSet
(Set of differently styled and sized icons)
- QImage
(Hardware-independent pixmap representation with direct access to the pixel data)
- QPalette
(Color groups for each widget state)
- QPen
(Defines how a QPainter should draw lines and outlines of shapes)
- QPixmap
(Off-screen pixel-based paint device)
- QString
(Abstraction of Unicode text and the classic C null-terminated char array (char*))
- QStringList
(A list of strings)
