Constructor Detail

public TableLayout()

Creates a new TableLayout object with no limits on the number of rows and columns.

Usage:

TableLayout layout = new TableLayout();

public TableLayout(int rows, int columns)

Creates a new TableLayout object with the specified number of rows and columns.

Usage:

TableLayout layout = new TableLayout(rows, columns);

Parameters:

rows	The number of rows, or 0 for no limit
columns	The number of columns, or 0 for no limit

public TableLayout(int rows, int columns, int hgap, int vgap)

Creates a new TableLayout object with the specified row count, column count, alignment, horizontal gap, and vertical gap.

Usage:

TableLayout layout = new TableLayout(rows, columns, hgap, vgap);

Parameters:

rows	The number of rows, or 0 for no limit
columns	The number of columns, or 0 for no limit
hgap	The horizontal gap between columns
vgap	The vertical gap between rows

Method Detail

public int getColumnCount()

Returns the number of columns in the table.

Usage:	int columns = layout.getColumnCount();
Returns:	The number of columns

public TableConstraints getConstraints(Component comp)

Returns a copy of the constraints requested for the specified component. The constraints value is always converted to a TableConstraints so that clients can use this class in preference to GridBagConstraints without needing a type cast.

Usage:

TableConstraints tc = layout.getConstraints(comp);

Parameter:

comp	The component whose constraints are requested

Returns:

A copy of the constraints object used to specify the layout

public int getDefaultFill()

Returns the default fill parameter for components in the table.

Usage:	int fill = layout.getDefaultFill();
Returns:	The default fill parameter for components in the table

public int getHgap()

Returns the horizontal gap between components.

Usage:	int hgap = layout.getHgap();
Returns:	The horizontal gap between components

public int getHorizontalAlignment()

Returns the horizontal alignment for the table.

Usage:	int align = layout.getHorizontalAlignment();
Returns:	The horizontal alignment for the table

public int getRowCount()

Returns the number of rows in the table.

Usage:	int rows = layout.getRowCount();
Returns:	The number of rows

public int getVerticalAlignment()

Returns the vertical alignment for the table.

Usage:	int align = layout.getVerticalAlignment();
Returns:	The vertical alignment for the table

public int getVgap()

Returns the vertical gap between components.

Usage:	int vgap = layout.getVgap();
Returns:	The vertical gap between components

public void setColumnCount(int columns)

Resets the number of columns in the table.

Usage:

layout.setColumnCount(columns);

Parameter:

columns

The new number of columns

public void setConstraints(Component comp, GridBagConstraints constraints)

Sets the constraints for the component to a copy of the supplied constraints.

Usage:

layout.setConstraints(comp, constraints);

Parameters:

comp	The component to be constrained
constraints	The constraints object used to specify the layout

public void setConstraints(Component comp, String constraints)

Sets the constraints for the component to the constraints specified by the string.

Usage:

layout.setConstraints(comp, constraints);

Parameters:

comp	The component to be constrained
constraints	A string specifying the constraints

public void setDefaultFill(int fill)

Sets the default fill parameter for components in the table. The legal values are NONE, HORIZONTAL, VERTICAL, and BOTH.

Usage:

layout.setDefaultFill(fill);

Parameter:

public void setHgap(int pixels)

Sets the horizontal gap between components.

Usage:

layout.setHgap(pixels);

Parameter:

pixels

The gap between components in pixels

public void setHorizontalAlignment(int align)

Sets the horizontal alignment for the table. The legal values are CENTER, LEFT, RIGHT, and FILL.

Usage:

layout.setHorizontalAlignment(align);

Parameter:

align

The horizontal alignment for the table

public void setRowCount(int rows)

Resets the number of rows in the table.

Usage:

layout.setVerticalAlignment(align);

Parameter:

align

The vertical alignment for the table
