toggleSelectionColors

private void toggleSelectionColors()

Toggle selection colors from focused to inactive and vice versa. This is not an optimal solution but much easier than rewriting the whole paint methods. Using a LaF specific renderer was avoided because often a custom renderer is already used in applications. Then either the inactive colors are not used, or the application has to be changed to extend a FlatLaf renderer.

paintCell

protected void paintCell(Graphics g,
 int row,
 Rectangle rowBounds,
 ListCellRenderer cellRenderer,
 ListModel dataModel,
 ListSelectionModel selModel,
 int leadIndex)

Overrides:

paintCell in class BasicListUI

paintCellSelection

protected void paintCellSelection(Graphics g,
 int row,
 int x,
 int y,
 int width,
 int height)

Paints (rounded) cell selection. Supports selectionArc and selectionInsets.

Note: This method is only invoked if either selection arc is greater than zero or if selection insets are not empty.

Since:

3

useUnitedRoundedSelection

private boolean useUnitedRoundedSelection(boolean vertical,
 boolean horizontal)

paintCellSelection

public static void paintCellSelection(JList<?> list,
 Graphics g,
 int row,
 int x,
 int y,
 int width,
 int height)

Paints a cell selection at the given coordinates. The selection color must be set on the graphics context.

This method is intended for use in custom cell renderers to support selectionArc and selectionInsets.
