The compiler uses char arrays instead of Strings. char arrays don't print nicely. That's why we have these nice toString() methods to help us debugging. The VA/Java debugger used to show them. The Eclipse debugger doesn't which makes debugging the compiler very painful. NOTES:

This is the presentation that has been agreed upon: * The variable view will contain a split pain with two viewers. * The first view is the variable tree view (as today) * The second view is a text view to display the 'toString()' of the selected variable. * A preference will control if the split is horizontal or vertical * The text view will be known as the 'detail area', and the variable view will support hide/show of details (with a toggle button in the toolbar) * By default, the detail area is hidden * The IDebugModelPresentation has been extended to support retrieval of detail for a value (#getDetail(IValue)). * When a variable is selected and the view is showing details, the debug model presentation for the appropriate debug model is queried to populate the detail view * the detail area will (at first) be a read only viewer that supports find & copy * I made a first cut of the implementation of #getDetail(IValue) for the JDIDebugModelPresentation
PRODUCT VERSION: R0.9
Implemented. Added TextViewer to VariablesView separated by sliding sash from variables tree. Added toggle action to toolbar to show/hide detail pane (current icon is borrowed from help.ui, we need a better icon, and one that has disabled and hover versions as well). Added Copy & Find actions to context menu for detail pane. Verified that context menus for tree viewer pane and detail pane can be contributed to independently. Added preference to debug preferences to control orientation of detail pane, choices are underneath or to the right of the tree veiwer pane.
There are several outstanding issues yet: - the detail pane always has scroll bars, whether needed or not, bug #5366 filed for this. - the sash has a flat, not 3D look. Only way to get a 3D look is to put borders on the widgets it separates, which looks wrong. Filed bug #5371 for this. - Need a real icon for the ShowVariableDetailPaneAction. Please verify.
Other issues: - need ability adjust split from vertical to horizontal (see drop down triangle menu on class hierarchy viewer as example) (#5422) - need pretty printers for Arrays (bug #1745) - detail area does not refresh (for example, while stepping through code that adds elements to a Vector, the toString() area does not update, but the variables view tree does update. (bug #5421)
Added artwork requests to bug #4383.
