NAME: SET_CONTROL (setctrl)
SYNOPSIS: Set Control - This control consists of 2
list boxes and 2 push buttons. The first
listbox consists of all the orginial strings and
the second listbox consists of all the strings
which transfer from the orginial listbox.
The 2 push buttons are: Add and Delete.
Add will add the current selected items from
the orginial listbox to the new listbox
Delete will move the selected item from the
new listbox to the orginial listbox
INTERFACE:
SET_CONTROL() - constructor
~SET_CONTROL() - destructor
DoAdd() - add items from the orginial listbox to the new
listbox
DoRemove() - move item from the new listbox to the
original listbox
EnableMoves() - enable and disable the set control's add and
delete buttons.
MoveItems() - redefine to move items from one listbox to another.
Use BLTMoveItems or subclass BLT_SET_CONTROL
for ordinary sorted BLT_LISTBOXes.
HandleOnLMouseButtonDown() The listboxes must redirect these events
HandleOnLMouseButtonUp() - to the corresponding SET_CONTROL. This
HandleOnMouseMove() implies that the listboxes must multiply
derive from CUSTOM_CONTROL.
PARENT: CONTROL_GROUP
NOTES: Drag and drop will not work unless you manage listbox events
properly. See the Handle* methods above for details.
