| SelectionChange | selectionChangeAct, | ||
| char * | newName, | ||
| int | size | ||

Member Function Documentation
| void addMenuNode | ( | MenuNode & | node ) |
Adds the given node to the Menu.
MenuNodes are ordered by the order in which they are added. Note that a Menu is also a MenuNode meaning that a menu can bee added as a MenuNode to create a sub Menu.
Menu root(&enterMenu, &selectNode, "root", 5); void main() { Menu *sub1 = new Menu(&enterMenu, &selectNode, "Settings", 5); MenuNode *ipnode = new MenuNode(&enterNode, &setip, "IP Address"); MenuNode *netmasknode = new MenuNode(&enterNode, &setmask, "Net mask"); sub1->addMenuNode(*ipnode); sub1->addMenuNode(*netmasknode); root.addMenuNode(*sub1); root.enter(); }
