範例
下列程式碼範例會在判斷 TreeNode 是否已選取傳入和 TreeNode 要選取的 之後,選取適當的 TreeNode 。 此範例需要您具有 Form 包含數 TreeNode 個 TreeView 物件的 控制項 TreeNodeCollection 。 它也需要您具有 ComboBox 下列專案的 :「Previous」、「PreviousVisible」、「Next」、「NextVisible」、「First」 和 「Last」。
void SelectNode( TreeNode^ node )
{
if ( node->IsSelected )
{
// Determine which TreeNode to select.
String^ str = myComboBox->Text;
if ( str->Equals( "Previous" ) )
node->TreeView->SelectedNode = node->PrevNode;
else
if ( str->Equals( "PreviousVisible" ) )
node->TreeView->SelectedNode = node->PrevVisibleNode;
else
if ( str->Equals( "Next" ) )
node->TreeView->SelectedNode = node->NextNode;
else
if ( str->Equals( "NextVisible" ) )
node->TreeView->SelectedNode = node->NextVisibleNode;
else
if ( str->Equals( "First" ) )
node->TreeView->SelectedNode = node->FirstNode;
else
if ( str->Equals( "Last" ) )
node->TreeView->SelectedNode = node->LastNode;
}
node->TreeView->Focus();
}
