Method Detail

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)

Parameters:

cellBounds - bounds of the cell containing the click

clickPt - usually the coordinates of a mouse click

getVerticalCellEdge

public static CellEdgeEnum getVerticalCellEdge(ILayer layer,
