Hi Jos,
i have experience on another ide b4j: “ABMaterial”. Alain here have made a nice work. here must write rows and columns in a page bild event and associate all components manually.
In xojo i think that we can use a form with a grid with columns and rows dinamics and define all the layout…
see this https://www.b4x.com/android/forum/threads/abmaterial-framework-for-webapps.60072/page-24
you can thing about this…
rubberviewswe is not the solution…
