void MyFrame::OnTreeSelection(wxTreeEvent& event) { if (event.GetText() == "Item 2") { // Skip the event, which will allow other event handlers to process it event.Skip(); } else { // Stop processing the event event.Veto(); } }
void MyDialog::OnTreeItemExpand(wxTreeEvent& event) { wxString itemText = GetItemText(event.GetItem()); if (itemText.Contains("Expandable")) { // Skip processing the event if the item's text contains "Expandable" event.Skip(); } else { // Do some custom processing ... } }In this example, we have an event handler for tree item expand events. If the item's text contains "Expandable", we skip processing the event. Otherwise, we perform some custom processing. wxTreeEvent Skip is part of the wxWidgets package library.
