Class FlowContainer

  • public class FlowContainer
extends Container
    This class is a Container that will place controls one after the other and, once the width has been reached, it wraps to next line. Example: 
     Settings.uiAdjustmentsBasedOnFontHeight = true;
 
 Label l = new Label("Do you agree that TotalCross is a great development platform?");
 l.autoSplit = true;
 add(l, LEFT,AFTER,PARENTSIZE+100,PREFERRED);
 
 FlowContainer fc = new FlowContainer(50,25);
 fc.add(new Radio("Probably Yes"));
 fc.add(new Radio("Probably No"));
 fc.add(new Radio("Maybe"));
 add(fc, LEFT,AFTER,PARENTSIZE+100,PREFERRED);
    All controls must be added before calling setRect. When calling setRect for this control, the height must be PREFERRED (with adjustments, if needed). Also, if initUI is overriden, be sure to call super.initUI(). IT IS VERY IMPORTANT THAT YOU USE PARENTSIZE+100 INSTEAD OF FILL IN THE WIDTH PARAMETER!
