Class RowDataFactory


  • public final class RowDataFactory
    extends Object
    This class provides a convenient shorthand for creating and initialising RowData. This offers several benefits over creating RowData the normal way:
    • The same factory can be used many times to create several RowData instances
    • The setters on RowDataFactory all return "this", allowing them to be chained
    Since:

      • copyData

        public static RowData copyData​(RowData data)
        Returns a copy of the given RowData
        Parameters:
        data - RowData to copy
        Returns:
        a copy of the argument
      • exclude

        public RowDataFactory exclude​(boolean shouldExclude)
        Instructs the GridLayout to ignore this control when performing layouts.
        Parameters:
        shouldExclude - true iff the control should be excluded from layouts
        Returns:
        this
      • create

        Creates a new GridData instance. All attributes of the GridData instance will be initialised by the factory.

        a new GridData instance
      • copy

        public RowDataFactory copy()
        Creates a copy of the receiver.
        Returns:
        a copy of the receiver
      • applyTo

        public void applyTo​(Control control)
        Sets the layout data on the given control. Creates a new RowData instance and assigns it to the control by calling control.setLayoutData.
        Parameters:
        control - control whose layout data will be initialised
      • hint

        public RowDataFactory hint​(int xHint,
                                   int yHint)
        Sets the width and height hints. The width and height hints override the control's preferred size. If either hint is set to SWT.DEFAULT, the control's preferred size is used.
        Parameters:
        xHint - horizontal hint (pixels), or SWT.DEFAULT to use the control's preferred size
        yHint - vertical hint (pixels), or SWT.DEFAULT to use the control's preferred size
        Returns:
        this
      • hint

        public RowDataFactory hint​(Point hint)
        Sets the width and height hints. The width and height hints override the control's preferred size. If either hint is set to SWT.DEFAULT, the control's preferred size is used.
        Parameters:
        hint - size (pixels) to be used instead of the control's preferred size. If the x or y values are set to SWT.DEFAULT, the control's computeSize() method will be used to obtain that dimension of the preferred size.
        Returns:
        this
