Guidelines
Is this the right control
- Provide a status bar in the main window of every standard application.
- Do not display a status bar in secondary or internal windows.
Behavior
- Do not use status bars for crucial information. Users should never have to know what is in the status bar. Otherwise consider to use tool-tips or a message panel.
- Do not use the status bar to display advisory messages in place of standard tool-tips.
- Do not make a status bar area interactive in standard applications. because those features are difficult to understand for non-experts.
Appearance
- When different information are shown the content of a status bar should be structured in panels.
- Keep the status bar plain; do not add icons.
