The debugger provides a powerful graphical user interface
based on OSF/Motif. You control the debugger by executing commands
from menus, from the command entry line, or from customizable command
buttons. (The debugger also has a line-mode user interface which
is described in Appendix A “
Line-Mode User Interface”.)
The main window of the debugger displays source code, debugger
output, and program I/O. Some of the features of the debugger main
window, shown in Figure 1-1 “Debugger Main Window”,
are:
Title not available (HP/DDE at a Glance )
- 1
Menu Bar
Invoke commands or display dialog boxes.
Some dialog boxes allow you to specify options to debugger
commands. Other dialog boxes include dynamic displays that allow
you to view and manipulate assembly code, registers, variables,
threads, call/return stacks, and more.
- 2
Input Box
Enter parameters for command buttons and pull-down menus.
You can enter information either by typing or by selecting
text (from the source code, debugger output, or program I/O areas)
for use with these commands. Text can be selected either by dragging
the mouse, or by double-clicking.
- 3
Interrupt Button
Interrupt the debugger or the target program.
This button changes from Interrupt Debugger
to Interrupt Program
when the target program is executing.
- 4
Location Buttons
Change current location up and down the call/return stack.
Indicators in this area show when the current location differs
from the program counter (PC)
location. Locations are specified as function names.
Title not available (HP/DDE at a Glance )
- 5
Annotation Margin
Shows source file line numbers.
Click with the left mouse button on a line number to set a
breakpoint. Click on the circled B
symbol to delete the breakpoint.
An arrow indicates the current program counter location.
- 6
Source File Display Area
Clicking the right mouse button in this area invokes the Source
Actions pop-up menu, which contains a number of program execution
and monitoring commands.
To search for text strings in the source file, select Visit:Search.
- 7
Customizable Command Buttons
Invoke common debugger commands.
You can change these buttons or create additional buttons
by selecting Options:User Configurable Buttons.
- 8
Debugger Output Area
This transcript pad echoes debugger commands, displays messages
and warnings, and displays the output from debugger commands.
- 9
Debugger Command Input Box
Enter debugger commands.
For a complete list of debugger commands, their options, and
usage examples see the online command reference.
- 10
User Program I/O Area
Target program output is displayed here. Input to target programs
is entered here.
The debugger's GUI often provides several methods of performing
a particular task. For example, you can:
Enter debugger commands in the command
input box.
Invoke actions from menus, dialog boxes, or command
buttons.
Invoke actions by pointing and clicking with the
mouse.
This manual attempts to describe the most common alternatives
for performing each task.
In general, entering debugger commands in the command entry
box provides the widest range of options and allows the greatest
flexibility and control. This manual shows only the more commonly
used options to debugger commands. For complete information on a
particular command, see Command Reference
in the debugger's online help. You can also enter help
command_name on the debugger's command
line.

 | NOTE: If, when you start HP/DDE 4.0, the main debugger window
does not look the way it does in Figure 1-1 “Debugger Main Window” (for example, if it is very small),
you probably have defined the X resource DDE.geometry
for an earlier release of HP/DDE. Comment out or remove this definition
from your X resources. |
