org.jdesktop.swingx.renderer.CheckBoxProvider
public class CheckBoxProvider
A component provider which uses a JCheckBox.
This implementation respects a BooleanValue and a StringValue to configure the button's selected and text property. By default, the selected is mapped to a Boolean-type value and the text is empty.
To allow mapping to different types, client code can supply a custom StringValue which also implements BooleanValue. F.i. to render a cell value of type TableColumnExt with the column's visibility mapped to the selected and the column's title to the text:
BooleanValue bv = new BooleanValue(){
public boolean getBoolean(Object value) {
if (value instanceof TableColumnExt)
return ((TableColumnExt) value).isVisible();
return false;
}
};
StringValue sv = new StringValue() {
public String getString(Object value) {
if (value instanceof TableColumnExt)
return ((TableColumnExt) value).getTitle();
return "";
}
};
list.setCellRenderer(new DefaultListRenderer(
new CheckBoxProvider(new MappedValue(sv, null, bv), JLabel.LEADING)));

public CheckBoxProvider()
public CheckBoxProvider(StringValue stringValue)
stringValue - the StringValue to use for formatting.
public CheckBoxProvider(StringValue stringValue,
int alignment)
stringValue - the StringValue to use for formatting.alignment - the horizontalAlignment.| Method Detail |

public boolean isBorderPainted()
setBorderPainted(boolean)public void setBorderPainted(boolean borderPainted)
The default value is true.
borderPainted - the borderPainted property to configure
the underlying checkbox with.isBorderPainted()protected void format(CellContext context)
Overridden to set the button's selected state and text.
PENDING: set icon?
format in class ComponentProvider<javax.swing.AbstractButton>context - the cell context to configure from, must not be null.getValueAsBoolean(CellContext),
ComponentProvider.getValueAsString(CellContext)protected boolean getValueAsBoolean(CellContext context)
This method messages the
BooleanValue to get the boolean rep. If none available,
checks for Boolean type directly and returns its value. Returns
false otherwise.
PENDING: fallback to check for boolean is convenient .. could cleanup to use a default BooleanValue instead.
context - the cell context, must not be null.
protected void configureState(CellContext context)
Here: set's the buttons horizontal alignment and borderpainted properties to this provider's properties.
configureState in class ComponentProvider<javax.swing.AbstractButton>context - the cell context to configure from, must not be null.protected javax.swing.AbstractButton createRendererComponent()
Here: returns a JCheckBox as rendering component.
