Create a B4X library from modules is very simple...and giving to the methods some hints is simple using line comments just before the Sub...but how to add description hints to the properties, to the classes and to the library itself? I tried in many ways and I've not found answers on the forum.
Is there anyone can help me?
You can add the hints to the class methods/properties in the exact same way, by placing comments just before the corresponding sub, you can even multiline them.
as to adding tooltips to classes and libs, I don't remember any lib to have a tooltip for the lib itself, nor a class.
That's correct. Sub comments will be added to the library.
The Class_Globals documentation will be added as the object documentation. Make sure to use B4J v4.7+.
Note that you can see it in the generated XML file.
