Constructor Detail

JxPanel

public JxPanel(LayoutManager layout,
               boolean isDoubleBuffered)

Creates a new JPanel with the specified layout manager and buffering strategy.

Parameters:

layout - the LayoutManager to use

isDoubleBuffered - a boolean, true for double-buffering, which uses additional memory space to achieve fast, flicker-free updates

JxPanel

public JxPanel(LayoutManager layout)

Create a new buffered JPanel with the specified layout manager

Parameters:

layout - the LayoutManager to use

JxPanel

public JxPanel(boolean isDoubleBuffered)

Creates a new JPanel with FlowLayout and the specified buffering strategy. If isDoubleBuffered is true, the JPanel will use a double buffer.

Parameters:

isDoubleBuffered - a boolean, true for double-buffering, which uses additional memory space to achieve fast, flicker-free updates

JxPanel

public JxPanel()

Creates a new JPanel with a double buffer and a flow layout.

Method Detail

getBaselineIdx

public int getBaselineIdx()

Get the index of the component, which should be used to determine the baseline of the panel.

If not set (i.e. the index is < 0), the panel will pick first component, which returns a baseline > -1 automatically. If otherwise out of range, i.e. the index points to a none-existing component, a baseline of -1 gets returned.

Returns:

-1 if not set, the index of the component otherwise.

See Also:

setBaselineIdx(int)

setBaselineIdx

public void setBaselineIdx(int baselineIdx)

Set the index of the component used to determine the baseline of this panel.

Parameters:

baselineIdx - index of the component to be used for baseline computation. If negativ, the first JComponent with a baseline > 0 will be used.

See Also:

getBaselineIdx(), Container.getComponent(int)

getBaseline

public int getBaseline(int width,
                       int height)

Get the baseline for this panel, or a value less than 0 if the baseline can not be determined. The baseline is measured from the top of the panel.

Overrides:

getBaseline in class JComponent

Parameters:

width - Width of the internal component to determine baseline for.

height - Height of the internal component to determine baseline for.

Returns:

baseline for the specified component
