void EnsureVisibleIfEnabled ( wxDataViewCtrl * aWidget, const wxDataViewItem & aItem )

inline

Scroll aItem into view only when aWidget is currently enabled.

On GTK, queueing scroll_to_path on a tree whose host frame has been disabled by a quasimodal child dialog races with concurrent model rebuilds and crashes GtkTreeView::validate_visible_area on the next frame-clock tick. The user can't see the scroll while the dialog is up anyway. wxWindow::IsEnabled() cascades through WINDOW_DISABLER on the parent frame, so this guard naturally suppresses the racy scroll for any quasimodal child.
