Constructor Detail

SimpleGrid

public SimpleGrid()
Creates a instance.


SimpleGrid

public SimpleGrid(java.lang.String[][] elements)
Creates new instance with elements.

Parameters:
elements - Elements of grid.
Method Detail

getColumnCount

public final int getColumnCount()
Returns current column count.

Specified by:
getColumnCount in interface Grid
Returns:
Column count.

getPreferredScrollableViewportSize

public java.awt.Dimension getPreferredScrollableViewportSize()
Returns the preferred size of the viewport for a view component. For example the preferredSize of a JList component is the size required to accommodate all of the cells in its list however the value of preferredScrollableViewportSize is the size required for JList.getVisibleRowCount() rows. A component without any properties that would effect the viewport size should just return getPreferredSize() here.

Specified by:
getPreferredScrollableViewportSize in interface javax.swing.Scrollable
Returns:
The preferredSize of a JViewport whose view is this Scrollable.
See Also:
JComponent.getPreferredSize()

getRowCount

public final int getRowCount()
Returns current row count.

Specified by:
getRowCount in interface Grid
Returns:
Tow count.

getScrollableBlockIncrement

public int getScrollableBlockIncrement(java.awt.Rectangle visibleRect,
                                       int orientation,
                                       int direction)
Specified by:
getScrollableBlockIncrement in interface javax.swing.Scrollable

getScrollableTracksViewportHeight

public boolean getScrollableTracksViewportHeight()
Return true if a viewport should always force the height of this Scrollable to match the height of the viewport. For example a columnar text view that flowed text in left to right columns could effectively disable vertical scrolling by returning true here.

Scrolling containers, like JViewport, will use this method each time they are validated.

Specified by:
getScrollableTracksViewportHeight in interface javax.swing.Scrollable
Returns:
True if a viewport should force the Scrollables height to match its own.

getScrollableTracksViewportWidth

public boolean getScrollableTracksViewportWidth()
Return true if a viewport should always force the width of this Scrollable to match the width of the viewport. For example a normal text view that supported line wrapping would return true here, since it would be undesirable for wrapped lines to disappear beyond the right edge of the viewport. Note that returning true for a Scrollable whose ancestor is a JScrollPane effectively disables horizontal scrolling.

Scrolling containers, like JViewport, will use this method each time they are validated.

Specified by:
getScrollableTracksViewportWidth in interface javax.swing.Scrollable
Returns:
True if a viewport should force the Scrollables width to match its own.

getScrollableUnitIncrement

public int getScrollableUnitIncrement(java.awt.Rectangle visibleRect,
                                      int orientation,
                                      int direction)
Components that display logical rows or columns should compute the scroll increment that will completely expose one new row or column, depending on the value of orientation. Ideally, components should handle a partially exposed row or column by returning the distance required to completely expose the item.

Scrolling containers, like JScrollPane, will use this method each time the user requests a unit scroll.

Specified by:
getScrollableUnitIncrement in interface javax.swing.Scrollable
Parameters:
visibleRect - The view area visible within the viewport
orientation - Either SwingConstants.VERTICAL or SwingConstants.HORIZONTAL.
direction - Less than zero to scroll up/left, greater than zero for down/right.
Returns:
The "unit" increment for scrolling in the specified direction. This value should always be positive.
See Also:
JScrollBar.setUnitIncrement(int)

removeAll

public void removeAll()
Removes all elements.

Overrides:
removeAll in class java.awt.Container

setCellColor

public void setCellColor(int row,
                         int column,
                         java.awt.Color color)
Sets the specified cell's foreground color.

Parameters:
row - target cell's row index.
column - target cell's column index.
color - color.

setCellSize

public void setCellSize(int width,
                        int height)
Sets width and height of grid cell.

Parameters:
width - Cell width.
height - Cell height.

setElements

public void setElements(java.lang.Object[][] elements)
sets elements. all previous elements are removed. remember that type of input parameter must be String[][].

Specified by:
setElements in interface Grid
Parameters:
elements - new elements

setElements

public void setElements(java.lang.String[] rowNames,
                        java.lang.String[] columnNames,
                        java.lang.String[][] elements)
Sets elements and row/column names. All previous elements are removed.

Parameters:
rowNames - Row names
columnNames - Column names
elements - New elements

setLayout

public final void setLayout(java.awt.LayoutManager layout)
You Can't overide this.

Overrides:
setLayout in class java.awt.Container
