getBaseline

public int getBaseline(JComponent c, int width, int height)
Returns the baseline.
Overrides:
getBaseline in class ComponentUI
Parameters:
c - JComponent baseline is being requested for
width - the width to get the baseline for
height - the height to get the baseline for
Returns:
baseline or a value < 0 indicating there is no reasonable baseline
Throws:
NullPointerException - if c is null
IllegalArgumentException - if width or height is < 0
Since:
1.6

getBaselineResizeBehavior

public Component.BaselineResizeBehavior getBaselineResizeBehavior(JComponent c)
Returns an enum indicating how the baseline of the component changes as the size changes.
Overrides:
getBaselineResizeBehavior in class ComponentUI
Parameters:
c - JComponent to return baseline resize behavior for
Returns:
an enum indicating how the baseline changes as the component size changes
Throws:
NullPointerException - if c is null
Since:
1.6
See Also:

getMinimumSize

public Dimension getMinimumSize(JComponent c)
Return the minimum size of the table. The minimum height is the row height times the number of rows. The minimum width is the sum of the minimum widths of each column.
Overrides:
getMinimumSize in class ComponentUI
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 or null
See Also:

getPreferredSize

public Dimension getPreferredSize(JComponent c)
Return the preferred size of the table. The preferred height is the row height times the number of rows. The preferred width is the sum of the preferred widths of each column.
Overrides:
getPreferredSize in class ComponentUI
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

public Dimension getMaximumSize(JComponent c)
Return the maximum size of the table. The maximum height is the row heighttimes the number of rows. The maximum width is the sum of the maximum widths of each column.
Overrides:
getMaximumSize in class ComponentUI
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 or null
See Also:

paint

public void paint(Graphics g, JComponent c)
Paint a representation of the table instance that was set in installUI().
Overrides:
paint in class ComponentUI
Parameters:
g - the Graphics context in which to paint
c - the component being painted; this argument is often ignored, but might be used if the UI object is stateless and shared by multiple components
