Erel B4X founder Staff member Licensed User Longtime User Mar 9, 2020 #2 Label.Height (not B4XView.Height) should return the real height when it is available. However you can also measure it with B4XCanvas or use BBLabel. Upvote 0

Search Results www.b4x.com It is available after the JavaFX engine finished to build the layout. There is no event that will help you.

I haven't found any documentation regarding PrefWidth and PrefHeight, except for something (insufficient for me) on JavaFX CSS Reference Guide, so I don't know what they are. If I start an empty project, with Main default size 600x600, the log of sizes returns Width 600 and PrefWidth -1 (same for height). [I thought there were specific booklets for the 4 platforms but that's not the case] Upvote 0
