| GridLayout | | final public class GridLayout extends Layout (Code) | | Instances of this class lay out the control children of a
Composite in a grid.
GridLayout has a number of configuration fields, and the
controls it lays out can have an associated layout data object, called
GridData. The power of GridLayout lies in the
ability to configure GridData for each control in the layout.
The following code creates a shell managed by a GridLayout
with 3 columns:
Display display = new Display();
Shell shell = new Shell(display);
GridLayout gridLayout = new GridLayout();
gridLayout.numColumns = 3;
shell.setLayout(gridLayout);
The numColumns field is the most important field in a
GridLayout. Widgets are laid out in columns from left
to right, and a new row is created when numColumns + 1
controls are added to the Composite.

| Constructor Summary | |
| public | GridLayout()
Constructs a new instance of this class. | | public | GridLayout(int numColumns, boolean makeColumnsEqualWidth)

| Method Summary | |
| protected Point | computeSize(Composite composite, int wHint, int hHint, boolean flushCache)
| | protected boolean | flushCache(Control control)
| | GridData | getData(Control[][] grid, int row, int column, int rowCount, int columnCount, boolean first)

| | public String | toString()
Returns a string containing a concise, human-readable
description of the receiver. |
| horizontalSpacing | | public int horizontalSpacing(Code) | | horizontalSpacing specifies the number of pixels between the right
edge of one cell and the left edge of its neighbouring cell to
the right.
The default value is 5.
|
| makeColumnsEqualWidth | | public boolean makeColumnsEqualWidth(Code) | | makeColumnsEqualWidth specifies whether all columns in the layout
will be forced to have the same width.
The default value is false.
|
| marginBottom | | public int marginBottom(Code) | | marginBottom specifies the number of pixels of vertical margin
that will be placed along the bottom edge of the layout.
The default value is 0.
since:
3.1 |
| marginHeight | | public int marginHeight(Code) | | marginHeight specifies the number of pixels of vertical margin
that will be placed along the top and bottom edges of the layout.
The default value is 5.
|
| marginLeft | | public int marginLeft(Code) | | marginLeft specifies the number of pixels of horizontal margin
that will be placed along the left edge of the layout.
The default value is 0.
since:
3.1 |
| marginRight | | public int marginRight(Code) | | marginRight specifies the number of pixels of horizontal margin
that will be placed along the right edge of the layout.
The default value is 0.
since:

The default value is 5.
|
| numColumns | | public int numColumns(Code) | | numColumns specifies the number of cell columns in the layout.
If numColumns has a value less than 1, the layout will not
set the size and position of any controls.
The default value is 1.
|
| verticalSpacing | | public int verticalSpacing(Code) | | verticalSpacing specifies the number of pixels between the bottom
edge of one cell and the top edge of its neighbouring cell underneath.

number of columns, and whether or not the columns
should be forced to have the same width.
If numColumns has a value less than 1, the layout will not
set the size and position of any controls.
Parameters:
numColumns - the number of columns in the grid
Parameters:
makeColumnsEqualWidth - whether or not the columns will have equal width
