I assume contentPanel is your HorizontalPanel. HorizontalPanel will generate an html table. You're setting the width of the panel.
If the width is wider than the sum of all widths of your sub widgets the table will spread the widgets evenly. Remove the setWidth() call.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
