public final class CellEdgeDetectUtil extends Object
  • Method Details

    • getColumnPosition

      public static int getColumnPosition(ILayer layer, org.eclipse.swt.graphics.Point clickPoint)
      Calculate the column position depending on the cursor's position on the left/right edges of the cell.
      Parameters:
      layer - The layer that should be used to calculate the column position. Typically the NatTable itself.
      clickPoint - The coordinate on which an action happened.
      Returns:
      the column position according to the cell edge.
      Since:
      1.6
    • getColumnPositionToResize

      public static int getColumnPositionToResize(ILayer layer, org.eclipse.swt.graphics.Point clickPoint)
      Calculate the column position to resize depending on the cursor's position on the left/right edges of the cell. Does not take into account columns which are not allowed to be resized.
      Parameters:
      layer - The layer that should be used to calculate the column position. Typically the NatTable itself.
      clickPoint - The coordinate on which an action happened.
      Returns:
      the column position according to the cell edge or -1 for an invalid column, e.g. the left edge of the first column, as a resize is not possible here.
    • getRowPosition

      public static int getRowPosition(ILayer layer, org.eclipse.swt.graphics.Point clickPoint)
      Calculate the row position to resize depending on the cursor's position on the top/bottom edges of the cell.
      Parameters:
      layer - The layer that should be used to calculate the row position. Typically the NatTable itself.
      clickPoint - The coordinate on which an action happened.
      Returns:
      the row position according to the cell edge.
      Since:
      1.6
    • getRowPositionToResize

      public static int getRowPositionToResize(ILayer layer, org.eclipse.swt.graphics.Point clickPoint)
      Calculate the row position to resize depending on the cursor's position on the top/bottom edges of the cell. Does not take into account rows which are not allowed to be resized.
      Parameters:
      layer - The layer that should be used to calculate the row position. Typically the NatTable itself.
      clickPoint - The coordinate on which an action happened.
      Returns:
      the row position according to the cell edge or -1 for an invalid row, e.g. the top edge of the first row, as a resize is not possible here.
    • getHorizontalCellEdge

      public static CellEdgeEnum getHorizontalCellEdge(org.eclipse.swt.graphics.Rectangle cellBounds, org.eclipse.swt.graphics.Point clickPt)
      Gets the edge (left/right) of the cell which is closer to the click point.
      Parameters:
      cellBounds - bounds of the cell containing the click
      clickPt - usually the coordinates of a mouse click
    • getHorizontalCellEdge

      public static CellEdgeEnum getHorizontalCellEdge(ILayer layer, org.eclipse.swt.graphics.Point clickPt)
    • getHorizontalCellEdge

      public static CellEdgeEnum getHorizontalCellEdge(ILayer layer, org.eclipse.swt.graphics.Point clickPt, int handleWidth)
    • getHorizontalCellEdge

      public static CellEdgeEnum getHorizontalCellEdge(org.eclipse.swt.graphics.Rectangle cellBounds, org.eclipse.swt.graphics.Point clickPt, int distanceFromEdge)
      Figure out if the click point is closer to the left/right edge of the cell.
      Parameters:
      cellBounds - of the table cell containing the click
      clickPt -
      distanceFromEdge - distance from the edge to qualify as close to the cell edge
    • getVerticalCellEdge

      public static CellEdgeEnum getVerticalCellEdge(org.eclipse.swt.graphics.Rectangle cellBounds, org.eclipse.swt.graphics.Point clickPt)
      Gets the edge (top/bottom) of the cell which is closer to the click point.
      Parameters:
      cellBounds - bounds of the cell containing the click
      clickPt - usually the coordinates of a mouse click
    • getVerticalCellEdge

      public static CellEdgeEnum getVerticalCellEdge(ILayer layer, org.eclipse.swt.graphics.Point clickPt)
    • getVerticalCellEdge

      public static CellEdgeEnum getVerticalCellEdge(ILayer layer, org.eclipse.swt.graphics.Point clickPt, int handleHeight)
