For each tab (if all tabs were requested to be previewed), the preview thumbnail will be offered to the relevant callback. This allows to maintain the interactivity of the application while generating the preview thumbnails for the tab overview dialog (seeTabOverviewDialog
).- Parameters:
previewInfo
- Tab preview info.
-
