IDE Window: Evaluate/Modify

Important

You must setup the debugger and start the project to debug it. Only then will this window be useful.

Evaluate/Modify

Interface

Evaluate

Evaluates the given expression

Modify

When the new values is set, it assigns the new value to the expression. The expression can only be a property or a variable. (Read notes on "New Value")

Watch

Add the expression to the watch list

Inspect

Show the variable inspector for the expression. The expression can only be a property or a variable.

Use Instance class type

Objects are normally shown according to the declaration of the watched expression. Evaluating "Sender: TObject" will only show you data, that is declared in 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.

Data

Expression

Enter the expression to be evaluated/modified/watched/inspected here

Result

The result of the evaluation. If the evaluation of the expression failed, an error message is shown.

New Value

The new value you want to use for a variable or property.

Important note on "New Value":

You should not attempt to modify "managed" types (strings, dynamic-array). This will lead to memory corruption.

There is currently no safety check in place. So you must ensure this yourself.
