Constructor Details

VariableHeightPanel

public VariableHeightPanel(boolean pack,
 int hgap,
 int vgap)

Construct a new VariableHeigthPanel.

Parameters:

pack - true means to fit as many components on a row, not worrying about lining up columns; false means to fit as many components on a row, and line up the columns as if in a grid

hgap - horizontal gap between components

vgap - vertical gap between components

Method Details

setBounds

public void setBounds(int x,
 int y,
 int width,
 int height)

Overrides:

setBounds in class Component

setBounds

public void setBounds(Rectangle r)

Overrides:

setBounds in class Component

setUseSingleLineLayout

public void setUseSingleLineLayout(boolean singleLineLayout)

This method is in place because the clients of this panel are not the ones that construct this panel and thus cannot create the desired type of layout at construction time. This method has no effect if this panel was constructed with pack set to false, which makes this panel use a grid style layout.

Parameters:

singleLineLayout - True signals to put all children on a single row; false will use as many rows as are needed to layout all of the children.

getPreferredLayoutSize

public Dimension getPreferredLayoutSize()

Return the preferred size of the layout manager of this panel.
