For those interested in the details of what I have found, my reports are entered in Github Codename One, assigned issue #4145.
I apologize for not checking here last night before I shut down. In addition to what I reported on Github in my afternoon report:
Since all my buttons are Styled by purpose, I have only found 2 other issues I have not mentioned.
Natural labels (tied to PreferredSize) which I had not Styled displayed at 1mm. Assigning the UIID yesterday to those labels I previously missed corrected this.
1 container I added a Styled label and Styled button to clipped the top and bottom of the text. The size of the container grew when the JFrame was resized, but the PreferredSize of the area in the container where the text is assigned did not grow. I will work on that container today and report back.
After what I identified yesterday and discussed on Github, I can Style around everything but PreferredSize, and if the Windows (or Desktop) API only allowed me to set the size of the JFrame for the initial form, I could adjust that starting point for PreferredSize and I think everything would fall into a useable place. As I noted in my report from yesterday afternoon, I think a starting size of 1280 x 1080 would work for both platforms.
