Description
TCustomButtonPanel is a
TCustomPanel descendant which
defines the base class for
TButtonPanel, a panel containing
buttons with glyph images. Buttons are provided for
OK,
Help,
Close, and
Cancel operations. Other properties are provided to
control the display order for the buttons, the default button for the panel,
visibility of the available buttons, and the use of glyphs.
Applications should not create instances of TCustomButtonPanel;
use the TButtonPanel ancestor which specifies the visibility of
properties (including event handlers).
