[X++] Auto expand whole tree in FormTreeControl
If you have a Tree control on your form and want to expand the whole tree with all items and subitems at once, you can use the following static method:
SysFormTreeControl::expandTree(FormTreeControl _formTreeControl, TreeItemIdx _treeItemIdx, int _toLevel = 0, int _level = 0)
For example to expand the whole tree from the root item to the inner most item:
SysFormTreeControl::expandTree(TreeCtrl, TreeCtrl.getRoot());
Or only from the current selection item down the tree:
SysFormTreeControl::expandTree(TreeCtrl, TreeCtrl.getSelection());
