Wichtig
Sie müssen den Debugger einrichten und das zu untersuchende Projekt starten. Nur dann wird dieses Fenster hilfreich sein.
Liste der überwachten Ausdrücke
The "Watch List" shows the values of variables and expressions ("watches") when the debugged application is paused. (e.g. reached a breakpoint).
Expressions can be local or global variables, (certain) properties, or pascal expressions (limited support, e.g. "a+1"). See here for more information
Angezeigte Daten
Die Anzeige besteht aus zwei Spalten:
- Ausdruck: der zu überwachende Ausdruck oder Variable
- Wert: der aktuelle Wert des Ausdrucks
Mit einem Doppelklick auf einen Eintrag kann dieser bearbeitet werden.
Scope (Stackframe, Thread, History)
The values are evaluated according to the scope set in the Thread and Stack dialog. Default is the current Thread and top stack frame. Both (Stack and Frame) dialog offer to change the "current" Frame/Thread. The watch window will follow this selection.
It is also possible to select previously displayed values, using the History dialog.
Spezielle Werte
- <invalid>
- Der Wert ist aktuell nicht verfügbar. Can be caused, if the debugger is not active or the debugged app not currently paused.
- <evaluating>
- Value is currently retrieved. A result will be show soon
- <disabled>
- The expression is excluded from evaluation. See Disable/Enable buttons (light bulbs)
- Error...
- The value could not be evaluated. (Error in Expression or Variable not available in selected scope.
Interface
Toolbar
Power- Enables/Disables all updates. This does not affect the enabled/disabled state of individual watches. This will freeze the current display.
Hinzufügen- Add a new expression. This will open the Watch property dialog. (It is also possible to double click an empty line in the list)
Aktivieren/
Deaktivieren- Enables/Disables individual watches from evaluation. This can be used to prevent spending time on evaluation, if a watch is not available in the current scope.
Löschen- Deletes the selected Watch(es)
Alle aktivieren/
Alle deaktivieren- Enables/Disables all watches from evaluation.
Alle löschen- Cleans the list
Eigenschaften- Change the expression or properties of the current/selected watch. (Also possible by double clicking the watch)
Kontextmenü
Zusätzlich zu den obigen Funktionen erlaubt das Kontextmenü:
- Überprüfung
- Opens the current watch in the Debug-Inspector
- Auswerten/Ändern
- Opens the current watch in the Evaluate/Modify window
- Datenhaltepunkt erzeugen
- Opens the dialog to create a new watchpoint based on the current watch (stop if wachted value is changed or accessed)
- Namen kopieren
- kopiert den Ausdruck in die Zwischenablage
- Wert kopieren
- kopiert den Wert in die Zwischenablage
Watch Properties
- Expression
- An Expression for which the evaluated value should be shown. Expressions can be local or global variables, (certain) properties, or pascal expressions (limited support, e.g. "a+1").
- Repeat Count
- Unimplemented
- Digits
- Unimplemented
- Enabled
- See Enable/Disable above
- Allow function calls
- Not yet supported
- Use Instance class type
- Objects are normally shown according to the declaration of the watched expression. Watching "Sender: TObject" will only show you data that is declared on TObject. However object variables can contain objects of inherited classes. Sender may be a TForm. Using this the debugger will find the actual class of the object and display all data.
- Style
- How to display the data. If a style can not be applied, default will be used.
"Repeat Count"
- is implemented in Lazarus 1.1 (SVN, trunk). It can be used to get array slices. The watch specifies the first element of the array "A[7]" (must have an index). With a "Repeat count" of 20, this shows A[7] to A[26].
- It can also be used with a dynamic array (no index given). Then it specifies haw many elements to show, beginning with DynA[0]
