Hi, I have a bean that inherits from JTextField and I need to prevent the WindowBuilder visual editor from allowing the developer to accidentally switch left and right sides thereby creating a component with a negative width. Is this something I can code in my component or an option I can configure in Eclipse?
I tried even by hard-coding a set of minimumSize in the constructor of my component to positive values, but to no avail.
Thanks,
Ben

No, there are no such feature.
Moreover, it would need to be done for each layout.
Do to this, you will need to integrate this check at model level, for example:
org.eclipse.wb.internal.swing.model.layout.absolute.AbsoluteLayoutInfo.setBoundsWidth(ComponentInfo, int)
org.eclipse.wb.internal.swing.model.layout.absolute.AbsoluteLayoutInfo.command_BOUNDS(ComponentInfo, Point, Dimension)
or at GEF level
org.eclipse.wb.internal.swing.model.layout.absolute.AbsoluteLayoutInfo.command_BOUNDS(ComponentInfo, Point, Dimension)
org.eclipse.wb.internal.core.gef.policy.layout.absolute.AbsoluteBasedSelectionEditPolicy.createResizeHandle(int)
