Method Detail

printer

ComponentPrinter printer()

Returns the ComponentPrinter in this finder.

Returns:

the ComponentPrinter in this finder.

findByType

<T extends Component> T findByType(Class<T> type)

Finds a Component by type. If this finder is attached to a Robot, it will use the component lookup scope in the Robot's Settings to determine whether the component to find should be showing or not. If this finder is not attached to any Robot, the component to find does not have to be showing.

Example:

 JTextField textbox = finder.findByType(JTextField.class);
 

Type Parameters:

T - the parameterized type of the component to find.

Parameters:

type - the type of the component to find.

Returns:

the found component.

Throws:

ComponentLookupException - if a matching component could not be found.

ComponentLookupException - if more than one matching component is found.

Robot.settings(), Settings.componentLookupScope(), ComponentLookupScope

findByType

<T extends Component> T findByType(Class<T> type,
                                 boolean showing)

Finds a Component by type. For example:

Type Parameters:

T - the parameterized type of the component to find.

Parameters:

type - the type of the component to find.

showing - indicates whether the component to find should be visible (or showing) or not.

Returns:

the found component.

findByType(Class)

findByType

<T extends Component> T findByType(Container root,
                                 Class<T> type)

Finds a Component by type in the hierarchy under the given root. If this finder is attached to a Robot, it will use the component lookup scope in the Robot's Settings to determine whether the component to find should be showing or not. If this finder is not attached to any Robot, the component to find does not have to be showing.

Let's assume we have the following JFrame containing a JTextField:

 JFrame myFrame = new JFrame();
 myFrame.add(new JTextField());
 

If we want to get a reference to the JTextField in that particular JFrame without going through the whole AWT component hierarchy, we could simply specify:

 JTextField textbox = finder.findByType(myFrame, JTextField.class);
 

Type Parameters:

T - the parameterized type of the component to find.

Parameters:

root - the root used as the starting point of the search.

type - the type of the component to find.

Returns:

the found component.

Throws:

ComponentLookupException - if a matching component could not be found.

ComponentLookupException - if more than one matching component is found.

Robot.settings(), Settings.componentLookupScope(), ComponentLookupScope

findByType

<T extends Component> T findByType(Container root,
                                 Class<T> type,
                                 boolean showing)

Finds a Component by type in the hierarchy under the given root.

Type Parameters:

T - the parameterized type of the component to find.

Parameters:

root - the root used as the starting point of the search.

showing - indicates whether the component to find should be visible (or showing) or not.

type - the type of the component to find.

Returns:

the found component.

Throws:

ComponentLookupException - if a matching component could not be found.

ComponentLookupException - if more than one matching component is found.

See Also:

findByType(Container, Class)

findByLabel

Component findByLabel(String label)

Finds a Component by by the text of its associated JLabel. If this finder is attached to a Robot, it will use the component lookup scope in the Robot's Settings to determine whether the component to find should be showing or not. If this finder is not attached to any Robot, the component to find does not have to be showing.

Let's assume we have the JTextField with a JLabel with text "Name";

 JLabel label = new JLabel("Name");
 JTextField textbox = new JTextField();
 label.setLabelFor(textBox);
 

To get a reference to this JTextField by the text of its associated JLabel, we can specify:

 JTextField textBox = (JTextField) finder.findByLabel("Name");
 

Please note that you need to cast the result of the lookup to the right type. To avoid casting, please use one of following:

1. findByLabel(String, Class)
2. findByLabel(String, Class, boolean)
3. findByLabel(Container, String, Class)
4. findByLabel(Container, String, Class, boolean)

Parameters:

label - the text of the JLabel associated to the component to find.

Returns:

the found component.

Throws:
