Message:

Updated all UI's StatusIndicator classes to use ActionStatusList.

• CommandLineStatusIndicator and TextStatusIndicator just print the message.
• QtStatusBar has a QTimer that updates the status message in second intervals.

Location:

src/UIElements/Views/Qt4

Files:

• QtStatusBar.cpp (modified) (5 diffs)
• QtStatusBar.hpp (modified) (5 diffs)
