TBaseVirtualTree.DetermineHiddenChildrenFlag Method
Determines whether all children of a given node are hidden.
Pascal
procedure DetermineHiddenChildrenFlag(Node: PVirtualNode); virtual;
Description
Virtual Treeview supports a feature, which is called node button auto hide. What happens is that when all children of a node are hidden then the expand button for this node is automatically removed. In order to know about the visibility state of the child nodes an internal flag is maintained, which allows to quickly decide about the button display. DetermineHidenChildren is the update method for cases where more than one child node changed.
