How to change text on stream group display in CDT eclipse debugger?

Question

I have a CDT based debugger and you want to add some information to the label in the node stream. I want the label surrounded by a red rectangle to display additional information (see screenshot below).

AFAIR, the format string for this label is set in the ThreadVMNode_No_columns__text_format property in the file C:\Users\...\workspace\org.eclipse.cdt.dsf.gdb.ui\src\org\eclipse\cdt\dsf\gdb\internal\ui\viewmodel\launch\MessagesForGdbLaunchVM.properties .

 # {0} - name available, 0=not available/1=available # {1} - name # {2} - ID available, 0=not available/1=available # {3} - ID # {4} - OS Thread ID available, 0=not available/1=available # {5} - OS Thread ID # {6} - Core available, 0=not available/1=available # {7} - Core # {8} - 0=running/1=suspended # {9} - state change reason available, 0=not available/1=available # {10} - state change reason # {11} - state change details available, 0=not available/1=available # {12} - state change details ThreadVMNode_No_columns__text_format={0,choice,0#Thread|1#{1}}{2,choice,0#|1# [{3}]}{4,choice,0#|1# {5}}{6,choice,0#|1# [core: {7}]} ({8,choice,0#Running|1#Suspended}{9,choice,0#|1# : {10}}{11,choice,0#|1# : {12}}) 

This format string is used in the org.eclipse.cdt.dsf.gdb.internal.ui.viewmodel.launch.ThreadVMNode.createLabelProvider() method:

 public class ThreadVMNode extends AbstractThreadVMNode implements IElementLabelProvider, IElementMementoProvider { [...] @Override protected IElementLabelProvider createLabelProvider() { PropertiesBasedLabelProvider provider = new PropertiesBasedLabelProvider(); provider.setColumnInfo( PropertiesBasedLabelProvider.ID_COLUMN_NO_COLUMNS, new LabelColumnInfo(new LabelAttribute[] { // Text is made of the thread name followed by its state and state change reason. new GdbExecutionContextLabelText( MessagesForGdbLaunchVM.ThreadVMNode_No_columns__text_format, new String[] { ExecutionContextLabelText.PROP_NAME_KNOWN, PROP_NAME, ExecutionContextLabelText.PROP_ID_KNOWN, ILaunchVMConstants.PROP_ID, IGdbLaunchVMConstants.PROP_OS_ID_KNOWN, IGdbLaunchVMConstants.PROP_OS_ID, IGdbLaunchVMConstants.PROP_CORES_ID_KNOWN, IGdbLaunchVMConstants.PROP_CORES_ID, ILaunchVMConstants.PROP_IS_SUSPENDED, ExecutionContextLabelText.PROP_STATE_CHANGE_REASON_KNOWN, ILaunchVMConstants.PROP_STATE_CHANGE_REASON, ExecutionContextLabelText.PROP_STATE_CHANGE_DETAILS_KNOWN, ILaunchVMConstants.PROP_STATE_CHANGE_DETAILS}), 

AFAIK, to add new information to the display, you must

• override the format string MessagesForGdbLaunchVM.properties and
• add a new row to the array of strings in a call to the GdbExecutionContextLabelText constructor.

What is the best way to do both of these things (it is advisable not to change the code of the main Eclipse / CDT classes)?

Update 1 (09/12/2014 19:56 MSK): I tried to use a custom debug presentation model by adding an extension, but the MyCompanyDebugModelPresentation class is not called anyhwere.

  <extension point="org.eclipse.debug.ui.debugModelPresentations"> <debugModelPresentation class="com.mycompany.internal.debug.ui.model.MyCompanyDebugModelPresentation" id="com.mycompany.internal.debug.ui.model.MyCompanyDebugModelPresentation"> </debugModelPresentation> </extension> 

Answer 1

To change the text shown above, you need to change several files and settings, which are shown in the matrix below.

You can read this image as follows:

• In your project, specify the extension point org.eclipse.core.run.adapters (the beginning of the red line) so that it points to
• your subclass of GdbAdapterFactory .
• Modify this class to return your subclass of GdbViewModelAdapter , etc.

You go through this chain until you reach the ThreadVMNode class (or your subclass), which determines which values ​​are displayed in the tree.
