Constructor Details

TableCursor
Constructs a new instance of this class given its parent table and a style value describing its behavior and appearance.The style value is either one of the style constants defined in class
SWT
which is applicable to instances of this class, or must be built by bitwise OR'ing together (that is, using theint
"|" operator) two or more of thoseSWT
style constants. The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses.- Parameters:
parent
- a Table control which will be the parent of the new instance (cannot be null)style
- the style of control to construct- Throws:
IllegalArgumentException
-- ERROR_NULL_ARGUMENT - if the parent is null
SWTException
-- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the parent
- ERROR_INVALID_SUBCLASS - if this class is not an allowed subclass

Method Details
-
addSelectionListener
Adds the listener to the collection of listeners who will be notified when the user changes the receiver's selection, by sending it one of the messages defined in theSelectionListener
interface.When
widgetSelected
is called, the item field of the event object is valid. If the receiver hasSWT.CHECK
style set and the check selection changes, the event object detail field contains the valueSWT.CHECK
.widgetDefaultSelected
is typically called when an item is double-clicked.- Parameters:
listener
- the listener which should be notified when the user changes the receiver's selection- Throws:
IllegalArgumentException
-- ERROR_NULL_ARGUMENT - if the listener is null
SWTException
-- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
- See Also:
-
setVisible
public void setVisible(boolean visible) Description copied from class:Control
Marks the receiver as visible if the argument istrue
, and marks it invisible otherwise.If one of the receiver's ancestors is not visible or some other condition makes the receiver not visible, marking it visible may not actually cause it to be displayed.
- Overrides:
setVisible
in classControl
- Parameters:
visible
- the new visibility state
-
removeSelectionListener
Removes the listener from the collection of listeners who will be notified when the user changes the receiver's selection.- Parameters:
listener
- the listener which should no longer be notified- Throws:
IllegalArgumentException
-- ERROR_NULL_ARGUMENT - if the listener is null
SWTException
-- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
- Since:
- 3.0
- See Also:
-
getColumn
public int getColumn()Returns the index of the column over which the TableCursor is positioned.- Returns:
- the column index for the current position
- Throws:
SWTException
-- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
-
getBackground
Returns the background color that the receiver will use to draw.- Overrides:
getBackground
in classControl
- Returns:
- the receiver's background color
-
getForeground
Returns the foreground color that the receiver will use to draw.- Overrides:
getForeground
in classControl
- Returns:
- the receiver's foreground color
-
getRow
Returns the row over which the TableCursor is positioned.- Returns:
- the item for the current position, or
null
if none - Throws:
SWTException
-- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
-
setBackground
Sets the receiver's background color to the color specified by the argument, or to the default system color for the control if the argument is null.Note: This operation is a hint and may be overridden by the platform. For example, on Windows the background of a Button cannot be changed.
- Overrides:
setBackground
in classControl
- Parameters:
color
- the new color (or null)- Throws:
IllegalArgumentException
-- ERROR_INVALID_ARGUMENT - if the argument has been disposed
SWTException
-- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
-
setForeground
Sets the receiver's foreground color to the color specified by the argument, or to the default system color for the control if the argument is null.Note: This operation is a hint and may be overridden by the platform.
- Overrides:
setForeground
in classControl
- Parameters:
color
- the new color (or null)- Throws:
IllegalArgumentException
-- ERROR_INVALID_ARGUMENT - if the argument has been disposed
SWTException
-- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
-
setSelection
public void setSelection(int row, int column) Positions the TableCursor over the cell at the given row and column in the parent table.- Parameters:
row
- the index of the row for the cell to selectcolumn
- the index of column for the cell to select- Throws:
SWTException
-- ERROR_WIDGET_DISPOSED - if the receiver has been disposed
- ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
-
setSelection
Positions the TableCursor over the cell at the given row and column in the parent table.- Parameters:
row
- the TableItem of the row for the cell to selectcolumn
- the index of column for the cell to select- Throws:
SWTException
