createMouseInputListener
Creates the mouse listener for theJTableHeader
.- Returns:
- the mouse listener for the
JTableHeader
-
createUI
Returns a new instance ofBasicTableHeaderUI
.- Parameters:
h
- a component.- Returns:
- a new instance of
BasicTableHeaderUI
-
installDefaults
protected void installDefaults()Initializes JTableHeader properties such as font, foreground, and background. The font, foreground, and background properties are only set if their current value is either null or a UIResource, other properties are set if the current value is null.- See Also:
-
installListeners
protected void installListeners()Attaches listeners to the JTableHeader. -
installKeyboardActions
protected void installKeyboardActions()Register all keyboard actions on the JTableHeader. -
uninstallDefaults
protected void uninstallDefaults()Uninstalls default properties -
uninstallListeners
protected void uninstallListeners()Unregisters listeners. -
uninstallKeyboardActions
protected void uninstallKeyboardActions()Unregisters default key actions. -
getRolloverColumn
protected int getRolloverColumn()Returns the index of the column header over which the mouse currently is. When the mouse is not over the table header, -1 is returned.- Returns:
- the index of the current rollover column
- Since:
- 1.6
- See Also:
-
rolloverColumnUpdated
protected void rolloverColumnUpdated(int oldColumn, int newColumn) This method gets called every time when a rollover column in the table header is updated. Every look and feel that supports a rollover effect in a table header should override this method and repaint the header.- Parameters:
oldColumn
- the index of the previous rollover column or -1 if the mouse was not over a columnnewColumn
- the index of the new rollover column or -1 if the mouse is not over a column- Since:
- 1.6
- See Also:
-
getBaseline
Returns the baseline.- Overrides:
getBaseline
in classComponentUI
- Parameters:
c
-JComponent
baseline is being requested forwidth
- the width to get the baseline forheight
- the height to get the baseline for- Returns:
- baseline or a value < 0 indicating there is no reasonable baseline
- Throws:
NullPointerException
- ifc
isnull
IllegalArgumentException
- if width or height is < 0- Since:
- 1.6
- See Also:
-
getMinimumSize
Return the minimum size of the header. The minimum width is the sum of the minimum widths of each column (plus inter-cell spacing).- Overrides:
getMinimumSize
in classComponentUI
- Parameters:
c
- the component whose minimum size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components- Returns:
- a
Dimension
object ornull
- See Also:
-
getPreferredSize
Return the preferred size of the header. The preferred height is the maximum of the preferred heights of all of the components provided by the header renderers. The preferred width is the sum of the preferred widths of each column (plus inter-cell spacing).- Overrides:
getPreferredSize
in classComponentUI
- Parameters:
c
- the component whose preferred size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components- Returns:
- a
Dimension
object containing given component's preferred size appropriate for the look and feel - See Also:
-
getMaximumSize
Return the maximum size of the header. The maximum width is the sum of the maximum widths of each column (plus inter-cell spacing).- Overrides:
getMaximumSize
in classComponentUI
- Parameters:
c
- the component whose maximum size is being queried; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components- Returns:
- a
Dimension
object ornull
