| '''Reduce the dialog flood'''
| |
| * Do not nest dialogs more than two levels deep.
| |
| <small>For example "Configuration dialog > Advanced dialog" is ok, "Configuration dialog > Advanced dialog > Further settings dialog" is too deep.</small>
| |
| | |
| * Avoid dialogs that contain only one or two options. If possible, use inline-editing instead.
| |
| <small> For example, to rename a list item, do not show a dialog but allow the user to change the label inside the list</small>
| |
| | |
| * Do not use dialogs to display non-critical messages which do not require any further user interaction (typically dialogs with a single "OK" or "Close" button). Use info panels instead.
| |
| <small>See [[Projects/Usability/HIG/Messages|Messages]]) </small>

| | |
| '''Position of dialogs'''
| |
| * Always keep dialogs on top of their parent.
| |
| <small>This is usually taken care of by the window manager. But in '''composed applications''', focus problems may occur. Check carefully in this case. </small>
| |
| | |
| * If reference in the parent window is required, make sure your dialog does not cover relevant parts.
| |
| <small>For example a find dialog should neither be centered, nor cover a search result. </small>
| |
| | |
| | |
| '''Interaction'''
| |
| * Set input focus on confirmation button.
| |
| | |
| | |
| '''Only use modal dialogs when''':
| |
| * Use modal dialogs only if allowing interaction with other parts of the application while the window is open could cause data loss or some other serious problem.
| |
| Provide a clear way of leaving the modal dialog, such as a Cancel button in an alert.
