Creates a new GridLayout using the specified settings.

Parameters:

makeColumnsEqualWidth - true to force all columns to have the same width; false if not to force sam width

marginHeight - the number of pixels of vertical margin that will be placed along the top and bottom edges of the layout

marginWidth - the number of pixels of horizontal margin that will be placed along the left and right edges of the layout

marginTop - the number of pixels of vertical margin that will be placed along the top edge of the layout

marginBottom - the number of pixels of vertical margin that will be placed along the bottom edge of the layout

marginLeft - the number of pixels of horizontal margin that will be placed along the left edge of the layout

marginRight - the number of pixels of horizontal margin that will be placed along the right edge of the layout

verticalSpacing - the number of pixels between the bottom edge of one cell and the top edge of its neighbouring cell underneath

horizontalSpacing - the number of pixels between the right edge of one cell and the left edge of its neighbouring cell to the right

Returns:

a GridLayout instance according to the specified settings

public static org.eclipse.swt.layout.GridData createGridData(int horizontalAlignment,
                                                             int verticalAlignment,

                                                             int heightHint)

Creates a new GridData object using the specified settings.

Parameters:

horizontalAlignment - specifies how controls will be positioned horizontally within a cell. Possible values are:

• SWT.BEGINNING (or SWT.LEFT): Position the control at the left of the cell
• SWT.CENTER: Position the control in the horizontal center of the cell
• SWT.END (or SWT.RIGHT): Position the control at the right of the cell
• SWT.FILL: Resize the control to fill the cell horizontally

verticalAlignment - specifies how controls will be positioned vertically within a cell. Possible values are:

• SWT.BEGINNING (or SWT.TOP): Position the control at the top of the cell
• SWT.CENTER: Position the control in the vertical center of the cell
• SWT.END (or SWT.BOTTOM): Position the control at the bottom of the cell
• SWT.FILL: Resize the control to fill the cell vertically

grabExcessHorizontalSpace - whether cell will be made wide enough to fit the remaining horizontal space

grabExcessVerticalSpace - whether cell will be made high enough to fit the remaining vertical space

horizontalSpan - the number of column cells that the control will take up

verticalSpan - the number of row cells that the control will take up

widthHint - the preferred width in pixels. This value is the wHint passed into Control.computeSize(int, int, boolean) to determine the preferred size of the control

heightHint - the preferred height in pixels. This value is the hHint passed into Control.computeSize(int, int, boolean) to determine the preferred size of the control

Returns:

a new GridData object according to the specified settings
