Constructor Detail

DoubleField

public DoubleField(org.eclipse.swt.widgets.Composite parent,
                   int style,
                   IPrintPreferences prefs,
                   int index)

Creates a new DoubleField.

Method Detail

setEnabled

public void setEnabled(boolean en)

Overrides:

setEnabled in class org.eclipse.swt.widgets.Control

updateControl

public void updateControl()

Updates control according to value in the IPrintPreferences. If it is the first update with an empty textfield, the preference value is set. If it is not the first time an empty text field occurs, nothing happens avoiding the confusing behaviour of updating to 0.00 when the user deletes all characters for preparing new input.

getText

public org.eclipse.swt.widgets.Text getText()

addModifyListener

public void addModifyListener(org.eclipse.swt.events.ModifyListener listener)

modifyText

public void modifyText(org.eclipse.swt.events.ModifyEvent e)

Specified by:

modifyText in interface org.eclipse.swt.events.ModifyListener
