Detailed Description

The interrelated classes TColorItem, TColorGroup, TColorSelector, TMonoSelector, TColorDisplay, TColorGroupList, TColorItemList, and TColorDialog provide viewers and dialog boxes from which the user can select and change the color assignments from available palettes with immediate effect on the screen.

TColorItemList is a simpler variant of TColorGroupList for viewing and selecting single color items rather than groups of colors.

Like TColorGroupList, TColorItemList is specialized derivative of TListViewer. Color items can be selected in any of the usual ways (by mouse or keyboard).

Unlike TColorGroupList, TColorItemList overrides the TListViewer event handler.

Constructor & Destructor Documentation

TColorItemList::TColorItemList ( const TRect & bounds, TScrollBar * aScrollBar, TColorItem * aItems )

Calls TListViewer constructor TListViewer(bounds, 1, 0, aScrollBar) to create a single-column list viewer with a single vertical scroll bar. Then, the constructor sets items data member to `aItems' and range to the number of items.

TColorItemList::TColorItemList ( StreamableInit ) [protected]

Each streamable class needs a "builder" to allocate the correct memory for its objects together with the initialized virtual table pointers. This is achieved by calling this constructor with an argument of type StreamableInit.
