OnToggleCheckbox用这个事件,
procedure TScopeForm.ScopeFcToggleCheckbox(TreeView: TfcCustomTreeView;
Node: TfcTreeNode);
var childnode:tfctreenode;
begin
childNode := node.getFirstChild;
while childNode <> Nil do
begin
//if not (nodes.Checked) then
childnode.checked:=node.Checked;
childNode := node.getNextChild(childNode);
end;
end;
