Implicitly and Explicitly Shared Classes

These classes are normally-heavy classes which in TQt 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 efficiently, even though they may seem heavyweight.

TQBitArray	Array of bits
TQBitmap	Monochrome (1-bit depth) pixmaps
TQBrush	Defines the fill pattern of shapes drawn by a TQPainter
TQCString	Abstraction of the classic C zero-terminated char array (char *)
TQCursor	Mouse cursor with an arbitrary shape
TQDeepCopy	Template class which ensures that implicitly shared and explicitly shared classes reference unique data
TQFont	Font used for drawing text
TQFontInfo	General information about fonts
TQFontMetrics	Font metrics information
TQIconSet	Set of icons with different styles and sizes
TQImage	Hardware-independent pixmap representation with direct access to the pixel data
TQMap	Value-based template class that provides a dictionary
TQPair	Value-based template class that provides a pair of elements
TQPalette	Color groups for each widget state
TQPen	Defines how a TQPainter should draw lines and outlines of shapes
TQPicture	Paint device that records and replays TQPainter commands
TQPixmap	Off-screen, pixel-based paint device
TQPointArray	Array of points
TQRegExp	Pattern matching using regular expressions
TQString	Abstraction of Unicode text and the classic C '\0'-terminated char array
TQStringList	List of strings
TQValueList	Value-based template class that provides lists
TQValueStack	Value-based template class that provides a stack
TQValueVector	Value-based template class that provides a dynamic array
