Edit Problem Pane
The PC2 Admin client interface (implemented by class ui.admin.AdministratorView) contains a Configure Contest tab which in turn contains a JTabbedPane containing a variety of tabs used to support configuring a contest. One of these is the Problems tab, which displays a grid of all currently configured contest problems (as well as allowing adding a new contest problem). Selecting an existing problem and then clicking the Edit Problem button displays an instance of class EditProblemFrame which in turn contains an instance of EditProblemPane.
The EditProblemPane class is an example of a PC2 JPanePlugin (that is, EditProblemPane extends JPanePlugin; see UI Design Elements). An EditProblemPane contains a JTabbedPane which in turn contains a variety of panes, one per tab. Many of the panes in the EditProblemPane's JTabbedPane are instances of JPanels constructed within the EditProblemPane (specifically, in method EditProblemPane.getMainTabbedPane()). Other panes in the JTabbedPane, however, are subclasses of the PC2 class JPanePlugin. Examples of the former include the General, Judging Type, and Output Validator tab panes, while examples of the latter include the Groups, Input Validator, and Test Data Files tab panes.
