Borland c++ builder onchange10/3/2023 Is it normal that both controls trigger when displayed over each other ? I can look into trying to disable TTreeView while the breadcrumb code is executing, so that the click is ignored, but I wonder if this is normal or if I'm missing something ? It's also not 100% which event ultimately 'wins' so the result is variable as well. This causes a conflict in my design as both events, the TListView item click and the TTreeView Onchange cause different things to be displayed/done. Meaning, the implementation is older, and worked perfectly before, but I have only just moved the breadcrumb control above the TTreeView control.Īnd I now notice that a click on a TListView Item from the breadcrumb control, also triggers the TTreeView OnChange event ! I have an application with a self created Breadcrumb control, positioned just above a TTreeView control, with TListView controls ( alClient inside TForms) as dropdown menus.
