Description
The given value is interpreted differently depending on the value of NodeAlignment (seeTBaseVirtualTree.NodeAlignment Property, page 126). By default the alignment used relatively with regard to the top bound. In this case a range of 0 through 100 must be used which denotes the relative pixel amount in percent. The other variants work with absolute pixel values from top or bottom bound.
