  • Constructor Details

    • MatrixPositionCoordPanel

      public MatrixPositionCoordPanel()
      Constructor.

  • Method Details

    • getVisibleCoordCount

      public int getVisibleCoordCount()
      Returns the number of coordinate entry fields currently visible.
      Returns:
      number of coord entry fields

    • getExtraTabs

      public List<uk.ac.starlink.util.Bi<String,JComponent>> getExtraTabs()
      Description copied from class: PositionCoordPanel
      Returns definitions for additional tabs to add alongside the main Position tab in the FormLayerControl. In most cases an empty list will be returned.
      Overrides:
      getExtraTabs in class PositionCoordPanel
      Returns:
      list of (TabName,TabContent) pairs to add

    • isPreferredCoord

      public boolean isPreferredCoord(uk.ac.starlink.ttools.plot2.data.Coord coord)
      Description copied from class: CoordPanel
      Indicates whether a coordinate is one that ought to get filled in if possible. The CoordPanel implementation simply returns coord.Coord.isRequired(), but subclasses can override this if more nuanced behaviour is necessary.

      In particular in order for autopopulation to work correctly, it may be necessary to return true for all members of a group of coordinates for which at least one has to be filled in for a viable plot.

      Overrides:
      isPreferredCoord in class CoordPanel
      Parameters:
      coord - candidate coordinate
      Returns:
      true if we should try hard to get a value

    • autoPopulate

      public void autoPopulate()
      Description copied from class: CoordPanel
      Makes some attempt to fill in the fields with non-blank values. The default implementation fills in the first few suitable columns, but subclasses are encouraged to override this behaviour if something smarter is possible.
      Overrides:
      autoPopulate in class CoordPanel

    • getCoords

      public uk.ac.starlink.ttools.plot2.data.Coord[] getCoords()
      Description copied from class: CoordPanel
      Returns the coordinates which this panel is getting values for.
      Overrides:
      getCoords in class CoordPanel
      Returns:
      coords

    • getAdditionalManagedCoords

      public uk.ac.starlink.ttools.plot2.data.Coord[] getAdditionalManagedCoords()
      Description copied from class: CoordPanel
      Returns a list of coordinates which do not correspond to the selectors displayed here, but which should not be acquired by other means.

      This is a hack to work round situations when coordinates are added into results by non-obvious means. In most cases the output result will be an empty array, which is what the implementation in this class does. But subclasses can override it for special behaviour.

      Overrides:
      getAdditionalManagedCoords in class CoordPanel
      Returns:
      list of coords which this panel will arrange to provide values for in some non-standard way

    • getContents

      public GuiCoordContent[] getContents()
      Description copied from class: CoordPanel
      Returns the coordinate values currently selected in this panel. If there is insufficient information to contribute to a plot (not all of the required coord values are filled in) then null will be returned.
      Overrides:
      getContents in class CoordPanel
      Returns:
      nCoord-element array of coord contents, or null

    • setTable

      public void setTable(TopcatModel tcModel, boolean autoFill)
      Description copied from class: CoordPanel
      Sets the table with reference to which this panel will resolve coordinate descriptions.

      If the existing selected coordinate values still make sense (if the new table has sufficiently compatible column names), they are retained. If the columns cannot be retained they are cleared, and in that case if the autopopulate parameter is set, some default columns will be used.

      Overrides:
      setTable in class CoordPanel
      Parameters:
      tcModel - table from which coordinate values will be drawn
      autoFill - whether to autopopulate columns when old ones can't be used or are absent
