Constructor Detail

DoubleFieldWithDropDown

public DoubleFieldWithDropDown(Composite parent,
                               int style,
                               IPrintPreferences prefs,
                               int index,
                               double[] defaults)

Creates a new DoubleFieldWithDropDown.

Method Detail

setEnabled

public void setEnabled(boolean en)

Overrides:

setEnabled in class 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 Object getText()

addModifyListener

public void addModifyListener(ModifyListener listener)

Specified by:
