thank u for the link. so it's not a separate functionality. i may not use it and still have its functionality by joining the dockable panes by hand in runtime. right?
if so, this is not what i'm looking for. i need the tab inside the pane. in another words i'm looking for a two-page pane. only one CDockablePane includes two pages of items which are selected with a tab control.
what is the best method to implement it?
