|
|
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.
