Constructor Detail

DefaultGridLook

public DefaultGridLook()

Constructs a DefaultGridLook with no border, no cell spacing, and no background colors.

DefaultGridLook

public DefaultGridLook(int horizontalSpacing,
                       int verticalSpacing)

Constructs a DefaultGridLook with the given cell spacing, and no border or background colors.

Parameters:

horizontalSpacing - the horizontal cell spacing.

verticalSpacing - the vertical cell spacing.

Method Detail

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

getCellBorder

public Border getCellBorder()

Returns the cell border. Default is an empty border with no margins.

Returns:

the cell border.

setCellBorder

public void setCellBorder(Border border)

Sets the cell border.

Parameters:

border - the cell border.

getCellSpacing

public org.eclipse.swt.graphics.Point getCellSpacing()

Returns the border spacing, in points, between adjacent grid cells. Default is (x=BORDER_OVERLAP, y=BORDER_OVERLAP).

Returns:

the border spacing, in points, between adjacent grid cells.

setCellSpacing

public void setCellSpacing(org.eclipse.swt.graphics.Point cellSpacing)

Sets the border spacing, in points, between adjacent grid cells. A value of BORDER_OVERLAP causes the borders to overlap, making the border appear continuous throughout the grid. A value of 0 or more causes the cell borders to be spaced that many points apart. 72 points = 1".

Parameters:

cellSpacing - a point whose x and y elements indicate the horizontal and vertical spacing between grid cells.

setCellSpacing

public void setCellSpacing(int horizontal,
                           int vertical)

Sets the border spacing, in points, between adjacent grid cells. A value of BORDER_OVERLAP causes the borders to overlap, making the border appear continuous throughout the grid. A value of 0 or more causes the cell borders to be spaced that many points apart. 72 points = 1".

Parameters:

horizontal - the horizontal cell spacing.

vertical - the vertical cell spacing.

getCellPadding

public org.eclipse.swt.graphics.Rectangle getCellPadding()

Returns a rectangle whose public fields denote the left (x), top (y), right (width) and bottom (height) cell padding, expressed in points. 72 points = 1" = 2.54cm.

Returns:

a rectangle whose public fields denote the cell padding at each edge.

setCellPadding

public void setCellPadding(org.eclipse.swt.graphics.Rectangle cellPadding)

Sets the cell padding to the values in the public fields of the argument.

Parameters:

cellPadding - the new cell padding.

setCellPadding

public void setCellPadding(int horizontalPadding,
                           int verticalPadding)

Sets the cell padding to the given horizontal and vertical values. This is equivalent to calling setCellPadding(horizontalPadding, verticalPadding, horizontalPadding, verticalPadding).

Parameters:

horizontalPadding - the amount of padding to add to the left and right of each cell, in points.

verticalPadding - the amount padding to add to the top and bottom each cell, in points.

setCellPadding

public void setCellPadding(int left,
                           int top,
                           int right,
                           int bottom)
