- public class GridA
- extends BaseA
GridA is an applet wrapper for the Grid widget. It is a general
purpose container for managing components in a grid layout. In
the applet version, any applets can be added to a grid cell
by specifying appropriate parameters in the applet tag.
Parameters supported by this applet includes:
- Grid.DEMO
- TRUE, display button to show style selection.
- Grid.SCROLLABLE
- if true, a Scroller is attached to
the grid.
- Grid.ROWS
- number of rows in grid.
- Grid.COLS
- number of columns in grid.
- Grid.CELL[$row,$col]
- $row is a number between 0 and Grid.ROWS-1. $col is a number
between 0 and Grid.COLS-1. They specify which cell the applet
should be added to. The value of this parameter is an URL for
an applet to be added to the specified cell.
If the child applet is a Tea Set applet, the applet id of the applet
is set to $row.$col. This means to pass parameter
specifically to the applet, the $row.$col needs to
to prepended to the parameter name. For example, if ImageButtonA is added
to row 2 column 5, the parameter for that ImageButtonA should be
1.4.ImageButton.IMAGE. If row/column number is not added to the front of
the parameter name, it will be used by all applet looking for the
parameter, instead of only for one specific applet. This targetting
mechanism is only true for Tea Set applets, unless the applet also
inherits from tea.set.BaseA and follow the same conventions as
explained in the Programming Guide.
- Grid.SPAN[$row,$col]
- this parameter specifies a spanning cell. A coresponding
Grid.CELL[$row,$col] must be supplied for this parameter to be
used. The value of the parameter is number of rows and number
of columns separated by an 'x', e.g. 2x3
- Grid.COLOR[$row,$col]
- a color value in the same formats supported by BaseA.FOREGROUND
parameter. It specifies the background color for the specified cell.
- Grid.ALIGN[$row,$col]
- this parameter specifies the alignment of a cell. A coresponding
Grid.CELL[$row,$col] must be supplied for this parameter to be
used. The value of the parameter is one of the nine possible
alignment flags, or a string containing one or two of H_LEFT,
H_CENTER, H_RIGHT, V_TOP, V_CENTER, and V_BOTTOM.
- Grid.GAP[$row,$col]
- this parameter specifies the gap of a cell. The value of this
parameter are four numbers separated by '-'. Each number specifies
the top, left, bottom, and right gap space respectively. e.g.
0-2-1-0.
- Grid.FREEZEROW
- The number of rows to freeze from the top of the grid. The frozen
rows will not be scrolled with other rows.
- Grid.FREEZECOL
- The number of columns to freeze from the left of the grid. The frozen
columns will not be scrolled with other columns.
- Grid.COLWIDTH
- comma separated list of column width (proportional)
If the list contains fewer than COLS columns, the rest of the column
will have the same width as specified at the last width in the list.
If this parameter is not specified, the column widths are calculated
automatically using the preferred size of cell components. For
detail, see Grid.
- Grid.ROWHEIGHT
- comma separated list of row heights (proportional)
If the list contains fewer than ROWS columns, the rest of the row
will have the same width as specified at the last height in the list.
If this parameter is not specified, the row heights are calculated
automatically using the preferred size of cell components. For
detail, see Grid.
- Grid.RULING
- '|' separated list of ruling style flags: VERTICAL,
HORIZONTAL, or ALL.
- Grid.RESIZABLE
- FALSE to disable user resize. Default is true.
- Grid.INPLACERESIZE
- TRUE to make resizing affecting both
rows/columns next to the resize line.
- Grid.ABSOLUTE
- TRUE to switch grid to absolute mode. Default
is false.
- Grid.3D
- line style for grid rulings: RAISED, LOWERED, and
PLAIN.
- Grid.LINEWIDTH
- 3D border line width. It should be larger than
one.
- Grid.ROWSELECTABLE
- TRUE to enable row select.
- Grid.COLSELECTABLE
- TRUE to enable column select.
- Grid.REGIONSELECTABLE
- TRUE to enable region select.
- Grid.MULTISELECT
- TRUE to enable multiple rows and/or columns
to be selected at one time.
- Grid.COLHEADER
- comma separated list of row headers.
- Grid.ROWHEADER
- comma separated list of column headers.
