Hi, In my GUI application, I have several JPanels that are instantiated at various points during the running of my program, and certain actions will cause one of them to be displayed in a scroll pane: mViewport.setViewportView(currentPanel); The trouble is, that my panels are done using Grid Bag Layouts, and the behaviour of that is ...
When making individual components of a layout managed by GridBagLayout invisible, the arrangement of the remaining components in the layout keeps changing.
