I am trying to add and remove action to welcome screen at run time on pressing Add and Delete buttons in Header Bar.
I am unable to append a new action item to welcome page at runtime.
check Code here
I can't check it currently, but this sounds like you are adding the widget and it simply doesn't show. When adding a new widget to
welcomeLayout.show_all () should show the new widget(s). You might want to run this after adding a new item in
public void addAWelcomeButton ().
