This method does the same as AddControl, except this method does not let the WindowSplitter manage resize for the control you assign to it. That is it will only move controls around.
ctrl as Control,
beforeSplitter as Boolean)
- The control to add to the WindowSplitter's list of managed controls.
- Set this parameter to true if the control that you are adding is before the WindowSplitter (To the left of it for vertical splitters or above for horizontal splitters), otherwise set to false. Since controls before the splitter only resize and not move then setting this to true will not let the splitter do anything to the control.
