The dialogs the console still extend from AbstractDialog. This dialog uses the native browser buttons. In the current Chrome these buttons appear now very small.
Solution: extend from Dialog instead.
Dialog also provides some sugar for common use cases like setting the dialog size and title:
- instead of overridding AbstractDialog#getProperties to return a ValueMap with width&height key-value pairs, call Dialog#setSize(DialogContants.MEDIUM_AUTO) in the constructor (see DialogConstants for all available OOTB sizes)
- instead of overriding AbstractDialog#getTitle, call Dialog#setTitle
In addition, Dialog has a bottom-left-slot that displays an EmptyPanel by default but can be used to, for example, display a bread-crumb widget (see AbstractBrowserDialog line 78) or a date-picker (see SchedulePublishDialog line 64).
