Is there a way to get the size of the selectable items in a TTMSFNCBloxSelector to scale or otherwise size themselves, or is the (rather large) size of the items fixed?
You can change the width & height with
TMSFNCBloxSelector1.Appearance.ItemHeight := 40;
TMSFNCBloxSelector1.Appearance.ItemWidth := 40;
But the items are auto-sizing themselves into the availble width. If you want smaller items you need to make the control less wide, or change the amount of columns
