Field Detail

DEFAULT_ALIGN

public static final int DEFAULT_ALIGN

The default alignment used when alignment is not specified. Value is SWT.LEFT.

Constant Field Values

DEFAULT_SIZE

public static final int DEFAULT_SIZE

Constant Field Values

DEFAULT_WEIGHT

public static final int DEFAULT_WEIGHT

The default weight used when weight is not specified. Value is 0.

Constant Field Values

size

public final int size

The size property for this GridColumn. Possible values:

• GridPrint.PREFERRED - indicates that the column should be as wide as the preferred width of its widest element.
• SWT.DEFAULT - Similar to GridPrint.PREFERRED, except that the column may shrink down to its minimum width if space is scarce.
• A value > 0 indicates that the column should be size points wide (72pts = 1").

align

public final int align

The default alignment for Prints in this column. Possible values are SWT.LEFT, SWT.CENTER, SWT.RIGHT, or SWT.DEFAULT. Note that alignment affects the placement of PrintPieces within the grid's cell--the alignment elements of the PrintPiece themselves are not affected. Thus, in order to achieve the desired effect, a Print having an alignment property should be set to the same alignment as the grid cell it is added to. For example, a TextPrint in a right-aligned grid cell should be set to right alignment as well.

Cells that span multiple columns use the alignment of the left-most cell in the cell span.

weight

public final int weight

The weight of this column. If the available print space is wider than the grid's preferred width, this field determines how much of that extra space should be given to this column. A larger weight causes the column to receive more of the extra width. A value of 0 indicates that the column should not be given any excess width.

Constructor Detail

GridColumn

public GridColumn(int align,
                  int size,
                  int weight)

Constructs a GridColumn.

Parameters:

align - The default alignment for Prints in this column.

size - The size this column should be given.

weight - The weight this column should be given.

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

parse

public static GridColumn parse(java.lang.String spec)

Parses the given column spec and returns a GridColumn matching that spec.

Format:

  [align:]size[:grow]
  
  align  = L | LEFT |
           C | CENTER |
           R | RIGHT
  size   = P | PREF | PREFERRED |
           D | DEF | DEFAULT |
           (Positive number)[PT|IN|INCH|CM|MM]
  weight = N | NONE |
           G | GROW | G(#) | GROW(#)
 

The default alignment is LEFT. The weight argument expresses the weight property: NONE indicates a weight of 0; GROW indicates a weight of 1; and GROW(3) indicates a weight of 3. The default weight (if weight is omitted) is 0.

Examples:

 LEFT:DEFAULT:GROW // left-aligned, default size, weight=1
  R:72PT:N          // light-aligned, 72 points (1") wide, weight=0
  right:72          // identical to previous line
  c:pref:none       // center-aligned, preferred size, weight=0
  p                 // left-aligned (default), preferred size, weight=0
  r:2inch           // right-aligned, 2 inches (50.8mm)
  r:50.8mm          // right-aligned, 50.8 mm (2")
 

Parameters:

spec - the column spec that will be parsed.

Returns:

a GridColumn matching the column spec.
