void MyListCtrl::OnListItemSelected(wxListEvent& event) { if (event.GetIndex() == 0) { // Prevent further processing of the event event.Skip(false); return; } // Allow the event to continue propagating event.Skip(); }
void MyListCtrl::OnListItemActivated(wxListEvent& event) { if (event.GetIndex() == 0) { // Show a message box indicating that the first item was activated wxMessageBox("You activated the first item!"); // Prevent further processing of the event event.Skip(false); return; } // Allow the event to continue propagating event.Skip(); }In this example, we define a method that is called when an item in the list control is activated (usually by double-clicking it). We check if the activated item is the first item in the list, and if so, we show a message box and prevent further processing of the event by calling Skip with a parameter of false. Otherwise, we allow the event to continue propagating by calling Skip with no parameters. Both of these examples use the wxListEvent class and its Skip method, which are part of the wxWidgets library.
