Debug tool window | Variables tab | context menu | Customize Data Views
Use this dialog to configure the debugger data view options.
Note that the same settings can be alternatively configured on
the Debugger page in the Settings
dialog.
Select this option to automatically scroll to new variables that appear in the scope when stepping.
Show value tooltip
Select this option to enable automatic display of tooltips for values.
A tooltip in this context is a pop-up that provides an alternative, sometimes a more
convenient presentation of values in the Variables pane of the
Debug tool window.
To illustrate, let's assume that there is a statement like this in your code:
Strings="Hello, World! \n Hello, World!";
When this statement is executed in the debugger, you'll see a line looking similar to this in the
Variables pane:
If the Show value tooltip option is on and you click this line and
then hold the mouse pointer on it, you’ll see a yellow area (the "tooltip") in which the value of
s is shown as
Hello, World! Hello, World!
with a real line break in place of\n.
If this option is disabled, press Alt to display a value.
Show
In this section, select which elements you want the Debugger to display:
Declared type
Synthetic fields
$val fields as local variables
Fully qualified names
Object id
Static fields
Static final fields
Show hex value for primitives
Select this option if you want numeric variables to be displayed in the hexadecimal format.
Hide null array elements
Select this option if you want null array elements to be omitted.
Enable alternative view for Collection classes
Select this option to display collections and maps in a more convenient format.
Enable toString() object view
In this section, you can select classes if you need them and their descendants to be presented as a
result of the toString() method call while debugging.
Use the following controls:
For all classes that override toString() method: select this option to show
all classes as toString().
For classes from the list: populate the list of classes to be shown as
toString(), using the, and
the buttons. Use the check boxes next to the class names to temporarily
enable or disable particular filters.
: click this button to add a class to the list using the
Choose Class dialog.
: click this button to add a custom class filter using the
New Filter dialog. To define a filter, enter a string pattern, e.g.
*.Test, javax.swing.*, etc.
: click this button to remove a filter from the list.
Java Data Type Renderers tab
On this tab, you can create and customize rendering schemes for data presentation in the
debugger Frame view.
If no rendering scheme is currently defined, start by clicking .
Item
Description
Use this icon to add a new rendering scheme to the list.
Use this icon to remove the selected scheme from the list.
Use this icon to create a copy of the selected scheme.
Use these icons to move the selected item one line up or down in the list.
Note that the order of items in the list determines which renderer is used in the case of
ambiguity born of class inheritance.
Renderer name
In this field, specify the name of a new renderer, or edit an existing renderer name.
Apply renderer to objects of type (fully-qualified name)
In this field, specify the type of objects that will be represented with this renderer. Type a fully
qualified object name, or click the Browse button
and choose the desired type from the list in the Renderer Reference Type dialog.
When rendering a node
This option determines how an object is displayed in the debugger when nodes are collapsed:
Use default renderer: select this option to display the node in the
default way.
Use following expression: enter the java expression you want to use to
identify an object. You can use object properties, constants, and even a string math as part
of your renderer.
Note that you can use code completion (Ctrl+Space) when defining
expressions.
All method calls and member variable access are relative to the object you're rendering.
Use this to refer to an instance to which the renderer applies.
When expanding a node
This option determines how an object is displayed in the debugger when nodes are expanded:
Normally, expanding a node in the debugger lists the object's member variables (using the
renderer appropriate for the corresponding object types).
This option lets you override this behavior and select a single expression or a series of
expressions to be displayed. You may use this to limit the amount of information displayed, or
to be more precise in how the information is presented.
Use default renderer: select this option to display the node children in
the default way.
Use following expression: enter the Java expression you want to use to
identify an object.
Test if a node can be expanded (optional): enter a Boolean
expression. If it istrue, the renderer displays expandable
nodes for the defined objects. Otherwise, no nodes are displayed.
Use list of expressions: create a list of separate expressions to be
calculated and presented as node children. Use:
(Alt+Insert) to create a new expression.
(Alt+Delete) to remove the selected expression from
the list.
(Alt+Up) to move the selected expression one
line up in the list.
(Alt+Down) to move the selected expression one
line down in the list.
Note that you can use code completion (Ctrl+Space) when defining
expressions.
