To add help button on aikau dashlet, can use widgetsForTitleBarActions?
Yes, this issue was raised on GitHub, cloned to JIRA and fixed in the 1.0.78 release.
The short answer is yes... I think that there was a fix made in this area so you may need a more recent version of Aikau, I need to check the change history and will let you know.
i have used new aikau-1.0.93 . now i can see label on title bar. but how can i use help button withing this?
label: "Title bar actions "
I'd recommend using AlfMenuBarItem or AlfMenuBarPopup (containing AlfMenuItem widgets) as the dashlet uses a menu bar. This tutorial chapter will give you a good overview. As with all widgets in Aikau the menu items will publish payloads on topics when clicked - those publications will need to be subscribed to by other widgets or services to have any effect.
when compare with surf dashlet , i can see smooth help button as following image. But if i use AlfMenuBarItem or AlfMenuBarPopup with aikau dashlet as help button , i can not see like that out put. how can i achieve?
There isn't a solution in Aikau that matches that exactly, however what you can do is use the AlfTooltip widget and nest an Image or SVGImage within it to render the question mark. Alternatively you could easily create your own custom tooltip widget that acts as you require.
