10.10.3 Modifying, Adding, Removing, and Resequencing Push Buttons

The buttons on the push button view are associated with debugger commands. You can:

Note

You cannot modify or remove the Stop button.

To save these modifications for future debugger sessions, choose Save Options from the Options menu.

Section 10.10.3.1, Section 10.10.3.2, and Section 10.10.3.3 explain how to customize push buttons interactively through the DECwindows Motif interface. You can also customize push buttons by editing the resource file. Button definitions in the resource file begin with:


DebugControl.Button 

(See Example 10-1.)

10.10.3.1 Changing a Button's Label or Associated Command

To change a button's label or associated command:

  1. Choose Customize Buttons... from the Options menu on the main window or the optional views window. The Customize Buttons dialog box is displayed (see Figure 10-23).
  2. Within the dialog box, click on the button you are modifying. This fills the Command and Label fields with the parameters for that button. The example in Figure 10-23 shows that the STEP button was selected.
  3. To change the button icon, pull down the Icon menu within the dialog box and select one of the predefined icons. As Figure 10-23 shows, the Label field dims and is filled with the debugger's internal name for the predefined icon. The icon itself appears in the dialog box's push button display.
    To change the button label, select None on the Icon menu and enter a new label in the Label field.
  4. To change the command associated with the button, enter the new command in the Command field. For online help about the commands, see Section 8.4.3.
    If the command is to operate on a name or language expression selected in a window, specify %S as the command parameter. For example, the following command displays the current value of the language expression that is currently selected:


    EVALUATE %s 
    

    If the command is to operate on a debugger built-in symbol or any other name that has a a percent sign (%) as the first character, specify two percent signs. For example:


    EXAMINE %%NEXTLOC 
    

  5. Click on Modify. The button's label or associated command is changed within the dialog box push button display.
  6. Click on Apply. The button's label or associated command is changed within the debugger's push button view.

To save these modifications for future debugger sessions, choose Save Options from the Options menu.

Figure 10-23 Changing the STEP Button Label to an Icon


10.10.3.2 Adding a New Button and Associated Command

To add a new button to the push button view and assign a debugger command to that button:

  1. Choose Customize Buttons... from the Options menu. The Customize Buttons dialog box is displayed (see Figure 10-24).
  2. Enter the debugger command for the new button in the Command field (see Section 10.10.3.1). Figure 10-24 shows the debugger command run mydisk:[mydirectory]x.exe was entered.
  3. Enter a label for that button in the Label field or choose a predefined icon from the Icon menu. Figure 10-24 shows that the Run-X label was chosen.
  4. Click on Add. The button is added to the dialog box push button display.
  5. Click on Apply. The button is added to the debugger's push button view.

To save these modifications for future debugger sessions, choose Save Options from the Options menu.

Figure 10-24 Adding a Button


10.10.3.3 Removing a Button

To remove a button:

  1. Choose Customize Buttons... from the Options menu on the main or optional views window. The Customize Buttons dialog box is displayed.
  2. Within the dialog box, click on the button you are removing. This fills the Command and Label fields with the parameters for that button.
  3. Click on Remove. The button is removed from the dialog box push button display.
  4. Click on Apply. The button is removed from the debugger's push button view.

To save these modifications for future debugger sessions, choose Save Options from the Options menu.

10.10.3.4 Resequencing a Button

To resequence a button:

  1. Choose Customize Buttons... from the Options menu on the main or optional views window. The Customize Buttons dialog box is displayed.
  2. Within the dialog box, click on the button you are resequencing. This fills the Command and Label fields with the parameters for that button.
  3. Click on the left or right arrow to move the button one position to the left or right. Continue to click until the button has moved, one position at a time, to its final position.
  4. Click on Apply to transfer this position to the debugger's push button view.

To save these modifications for future debugger sessions, choose Save Options from the Options menu.

10.10.4 Editing the Debugger Resource File

The debugger is installed on your system with a default debugger resource file (DECW$SYSTEM_DEFAULTS:VMSDEBUG.DAT) that defines the default display configuration for the debugger. When you modify the display attributes as described in Section 10.10 and then save the modifications with the Save Options command in the Options menu, the debugger creates a local debugger resource file, DECW$USER_DEFAULTS:VMSDEBUG.DAT. You can edit this file to further modify the debugger display configuration.

If you do not have a local debugger resource file, you can create one with the Restore Default Options item in the Options menu. Whenever you start the debugger, it creates the debugger display configuration as defined in the most recent version of the local debugger resource file if there is one, otherwise, the debugger uses the definitions in the system debugger resource file, DECW$SYSTEM_DEFAULTS:VMSDEBUG.DAT.

You cannot edit the system resource file. You can modify the debugger display configuration only by following the procedures in Section 10.10.1, Section 10.10.2, and Section 10.10.3, or by editing and saving your local debugger resource file.

Example 10-1 contains a copy of the system default debugger resource file. Most entries are annotated within the file or are self-explanatory. Section 10.10.4.1, Section 10.10.4.2, Section 10.10.4.3, and Section 10.10.4.4 contain additional information about modifying certain key sequences. For complete information about specifying key sequences, see the translation table syntax in the X Toolkit Intrinsics documentation.

Note

The line in Example 10-1 that begins with DebugControl.ButtonList does not completely fit in this example. This line identifies the button definitions contained in the file. The full line in the file also contains the following button names: StepReturnButton, StepCallButton, ExamineButton, ExamineASCIZButton, ExamineASCICButton, EvalButton, MonitorButton.

10.10.4.1 Defining the Key Sequence to Display the Breakpoint Dialog Box

By default, the key sequence for displaying the dialog box for conditional and action breakpoints is Ctrl/MB1 (see Section 10.4.6 and Section 10.4.7). To define another key sequence, edit the current definition of the following resource in the resource file. For example:


DebugSource.ModifyBreakpointToggleSequence:   Ctrl<Btn1Down>(2) 

10.10.4.2 Defining the Key Sequence for Language-Sensitive Text Selection

By default, the key sequence for language-sensitive text selection in the main window and instruction view is Ctrl/MB1 (see Section 10.5.1). To define another key sequence, edit the current definition of the following resource in the resource file. For example:


DebugSource.IdentifierSelectionSequence:  Ctrl<Btn1Down> 

To avoid conflict with standard DECwindows Motif word selection, do not use a double-click combination, such as Ctrl<Btn1Down>(2).

10.10.4.3 Defining the Font for Displayed Text

To define another font for the text displayed in various debugger windows and views, edit the current definition of the following resources in the resource file. For example:


DebugDefault.Font:  -*-COURIER-BOLD-R-*--*-120-*-*-*-*-ISO8859-1 

10.10.4.4 Defining the Key Bindings on the Keypad

To bind a different command to a key that is already associated with a command, edit the current definition of the following resources in the resource file. For example:


    <literal>(<Key>)0xFFB0: EnterCmdOnCmdLine("step/line 3") \n\

To bind a command to a key that is not currently associated with a command, refer to the Keysym Encoding chapter of the X and Motif Quick Reference Guide for key designations.

10.11 Debugging Detached Processes

You cannot use the DECwindows Motif interface to the debugger to debug detached processes, such as print symbionts, which run without a command line interpreter (CLI).

To debug a detached process that runs without a CLI, use the character-cell (screen mode) interface to the debugger (see Section 1.12).
