Method Detail

getValueProperty

public org.eclipse.core.databinding.property.value.IValueProperty getValueProperty()

Returns the IValueProperty for this cell editor which is used by the table to create an IObservableValue.

Returns:

See Also:

ECPCellEditor.getValueProperty()

instantiate

public void instantiate(org.eclipse.emf.ecore.EStructuralFeature eStructuralFeature,
                        ViewModelContext viewModelContext)

Instantiates this cell editor. This allows the cell editor to use ViewModelServices.

Parameters:

eStructuralFeature - the EStructuralFeature displayed in this cell editor

viewModelContext - the ViewModelContext used for the current view

See Also:

ECPCellEditor.instantiate(org.eclipse.emf.ecore.EStructuralFeature, org.eclipse.emf.ecp.view.spi.context.ViewModelContext)

getFormatedString

public String getFormatedString(Object value)

This returns the String which will be shown in the table when no cell editor is open.

Parameters:

value - the Object to get the formated String for

Returns:

the formated String

See Also:

ECPCellEditor.getFormatedString(java.lang.Object)

getColumnWidthWeight

public int getColumnWidthWeight()

The returned value is used for layouting the table columns. The value is a relative column weight. A column containing text has a weight of 100. Please consider this when defining you weight. E.g if you return 200 your column will be twice the width of a text column.

Returns:

the relative column width
