Constructor Detail

PageTableCellInfo

public PageTableCellInfo(com.klg.jclass.page.JCPageTable table,
                         int row,
                         int column)

Creates a TableCellInfo object for a given table cell.

Parameters:

table - The table the cell belongs to

row - The row index of the cell in the table

column - The column index of the cell in the table

Method Detail

getBackground

public Color getBackground()

Returns the background colour of the cell being displayed.

Specified by:

getBackground in interface JCCellInfo

Returns:

The colour to draw in the cell's background

getForeground

public Color getForeground()

Returns the foreground colour of the cell being displayed.

Specified by:

getForeground in interface JCCellInfo

Returns:

The colour to draw the cell's foreground in

getSelectedBackground

public Color getSelectedBackground()

Returns the background color of the cell being displayed when the cell is selected.

Specified by:

getSelectedBackground in interface JCCellInfo

Returns:

The colour to draw in the cell's background

getSelectedForeground

public Color getSelectedForeground()

Returns the foreground color of the cell being displayed when the cell is selected.

Specified by:

getSelectedForeground in interface JCCellInfo

Returns:

The color to draw the cell's foreground in

getFont

public Font getFont()

Returns the font of the cell being displayed.

Specified by:

getFont in interface JCCellInfo

Returns:

The font used to draw the cell

getHorizontalAlignment

public int getHorizontalAlignment()

Returns the horizontal alignment for the cell being displayed.

Specified by:

getHorizontalAlignment in interface JCCellInfo

Returns:

The position of the cell contents relative to the column

getVerticalAlignment

public int getVerticalAlignment()

Returns the vertical alignment for the cell being displayed.

Specified by:

getVerticalAlignment in interface JCCellInfo

Returns:

The position of the cell contents relative to the row space

getMarginInsets

public Insets getMarginInsets()

Returns the Insets object representing the margins for the cell.

This method should be applied to editor components but not to renderer components since the renderer has already been mapped inside the area bounded by the margins and borders.

Specified by:

getMarginInsets in interface JCCellInfo

Returns:

Insets object representing the margins for the cell

getBorderInsets

public Insets getBorderInsets()

Returns the Insets object representing the borders for the cell.

This method should be ignored by editor and renderer components since the editor is deliberately made bigger than the renderer by this amount.

Specified by:

getBorderInsets in interface JCCellInfo

Returns:

Insets object representing the borders for the cell

getBorderStyle

public int getBorderStyle()

Returns the border style for the cell. Renderers and Editors should ignore this value.

Specified by:

getBorderStyle in interface JCCellInfo

Returns:

border style for the cell

getDrawingArea

public Rectangle getDrawingArea()

Returns the dimensions of the drawing area for the cell being displayed. When the renderer's draw() method is called, the gc is translated to the upper left-hand corner of the drawing area for the cell. As a result, the (x,y) of the Rectangle are always (0,0).

Specified by:

getDrawingArea in interface JCCellInfo

Returns:

size of the drawing area.

setDrawingArea

public void setDrawingArea(Rectangle rect)

isEditable

public boolean isEditable()

Determines whether the cell is editable.

Specified by:

isEditable in interface JCCellInfo

Returns:

Always returns false for PageLayout tables

isEnabled

public boolean isEnabled()

Determines whether the cell is enabled.

Specified by:

isEnabled in interface JCCellInfo

Returns:

getSelectAll

public boolean getSelectAll()

Determines whether the editor should select the contents before editing.

Specified by:

getSelectAll in interface JCCellInfo

Returns:

Always returns false for PageLayout tables

getClipHints

public int getClipHints()

Determines whether the renderer should draw some indication if the entire contents of the cell cannot be rendered within the given area.

Specified by:

getClipHints in interface JCCellInfo

Returns:

getDataType

public Class getDataType()

Returns the cell's associated data type.

Specified by:

getDataType in interface JCCellInfo

Returns:

cell's associated data type
