Title: Help simple scroll pane problem

Hi Aaron
You are not adding anything to the scrollpane.....so by default it is not shown.......

Default:    jScrollPane1.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED); 

 

U can override it using jScrollPane1.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS ); 

 

Similarly u can set the scrollbar policy for Vertical scrollbar

 

Hope this gets u started

 

Regards

Harkishin
