|

| 32 | The Tree Model Completer example shows how to provide completion
|
|---|
| 33 | facilities for a hierarchical model, using a period as the separator
|
|---|
| 34 | to access Child, GrandChild and GrandGrandChild level objects.

| 38 | Similar to the \l{Completer Example}, we provide QComboBox objects to
|

| 39 | enable selection for completion mode and case sensitivity, as well as
|

|
|---|
| 59 | \l{QCompleter::splitPath()}{splitPath()} and
|
|---|
| 60 | \l{QCompleter::pathFromIndex()}{pathFromIndex()} to suit a tree model.
