Package org.eclipse.nebula.widgets.nattable.edit.gui

Class TickUpdateCellEditDialog

  • All Implemented Interfaces:
    org.eclipse.jface.window.IShellProvider, ICellEditDialog
    public class TickUpdateCellEditDialog
extends CellEditDialog
    Specialization of CellEditDialog that adds additional functionality to also use tick updates on the cell value(s). By selecting another edit type than set, the value entered in the editor control will be processed with the current value instead of simply setting this value. As using e.g. increase/decrease on the current value allows different values than on set, the validator needs to be wrapped so it is skipped for entering the value for processing.

      • TickUpdateCellEditDialog

        public TickUpdateCellEditDialog​(org.eclipse.swt.widgets.Shell parentShell,
                                Object originalCanonicalValue,
                                ILayerCell cell,
                                ICellEditor cellEditor,
                                IConfigRegistry configRegistry,
                                ITickUpdateHandler tickUpdateHandler)
        Parameters:
        parentShell - the parent shell, or null to create a top-level shell
        originalCanonicalValue - The value that should be propagated to the editor control. Needed because for multi cell editing or editor activation by letter/digit key will result in a different value to populate for some editors than populating the value out of the cell/data model directly.
        cell - The cell that should be edited. Needed because editor activation retrieves the configuration for editing directly out of the cell.
        cellEditor - The ICellEditor that will be used as editor control within the dialog.
        configRegistry - The IConfigRegistry containing the configuration of the current NatTable instance the command should be executed for. This is necessary because the edit controllers in the current architecture are not aware of the instance they are running in and therefore it is needed for activation of editors.
        tickUpdateHandler - The ITickUpdateHandler that will be used to process the tick updates after closing this editor by pressing ok.

    • Method Detail

      • createDialogArea

        protected org.eclipse.swt.widgets.Control createDialogArea​(org.eclipse.swt.widgets.Composite parent)
        Overrides:
        createDialogArea in class CellEditDialog

      • getEditType

        public EditTypeEnum getEditType()
        Specified by:
        getEditType in interface ICellEditDialog
        Overrides:
        getEditType in class CellEditDialog
        Returns:
        The edit type that has impact on how the set value will be updated to the data model. By default EditTypeEnum.SET is returned, which will simply set the committed value to the data model. Every other edit type will do some calculation based on the committed value and the current value in the data model.

      • calculateValue

        public Object calculateValue​(Object currentValue,
                             Object processValue)
        Description copied from class: CellEditDialog
        In case ICellEditDialog.getEditType() returns an edit type for processing values, this method should implemented to do that transformation.
        Specified by:
        calculateValue in interface ICellEditDialog
        Overrides:
        calculateValue in class CellEditDialog
        Parameters:
        currentValue - The current value for the cell before data model update
        processValue - The value committed to the editor that should be used for calculation on the current value.
        Returns:
        This implementation will always return processValue, as there is no processing specified in this ICellEditDialog implementation and therefore the value that was committed to the editor will be updated to the data model.
