[POST-VIS] Give warning if there is no contact data
[POST-VIS] Give warning if there is no contact data
Problem to solve
First problem
If there is no contact data file contacts.txt, the pushbutton "show_contacts" in PostVisualizationWindow is useless. If the user pushes the button, nothing happens.
Second problem
If you move your cursor onto the pushbutton "show_contacts", it says
!ProjectView.btnShowContacts.tooltip!
instead of
show contacts
Further details
- Give the user feedback, that his action has no effect since there is no contact data file "contacts.txt" provided.
- Show
show contacts
instead of!ProjectView.btnShowContacts.tooltip!
