Constructor Detail

DataTextField

public DataTextField(int length,
                     DataObject dO,
                     java.lang.String columnName)

Constructs a new database assigned text field with the specified length (used for size and max length), data object and column name.

Parameters:

length - of the text field - size relevant

dO - the data object to assign to

columnName - the name of the column the text field is to assign to

DataTextField

public DataTextField(int length,
                     int maxChars,
                     DataObject dO,
                     java.lang.String columnName)

Constructs a new database assigned text field with the specified length (size), max chars, data object and column name.

Parameters:

length - of the text field - size relevant

maxChars - input control relevant max character length of the text field

dO - the data object to assign to

columnName - the name of the column the text field is to assign to

Method Detail

getAssignedDataObject

public DataObject getAssignedDataObject()

Specified by:

getAssignedDataObject in interface DataComponent

Returns:

the assigned data object

loadValue

public void loadValue()

Description copied from interface: DataComponent

Loads the component's database stored value.

Specified by:

loadValue in interface DataComponent

isToSave

public boolean isToSave()

Description copied from interface: DataComponent

Indicates whether the component's value differs from its value at load time.

Specified by:

isToSave in interface DataComponent

Returns:

true if the component's value differs from its value at load time

isContentValid

public boolean isContentValid()

Description copied from interface: DataComponent

Indicates whether the component's value is valid.

Specified by:

isContentValid in interface DataComponent

Returns:

true if the component's value is valid

selectAll

public void selectAll()

Description copied from interface: DataComponent

Overrides:

keyReleased in class MustTextField

Parameters:

e - the key event

addComponentModificationListener

public void addComponentModificationListener(ComponentModificationListener l)

Description copied from interface: DataComponent

Adds a component modification listener to this component. Needed e.g. for data components depending from a sublist.
