Class CellRendererStateSupport
When creating a cell renderer that has more than one component to manage state of (such as a JLabel
for
the icon, and a JTextArea
for the text), this class can be used to coordinate the cell states so
that all the components are in sync: the correct background and foreground for the selected state, eg.
Handles the following renderer state of cells:
- Selected/Not Selected
- Enabled/Disabled
- Focused (see constructor for which components gets the focused border)
The following properties will be set for components supported by this class:
- Background
- Foreground
If the passed component is a JLabel
and the label has a CellRendererIcon
For labels with no icons set in the initial state (the icon for these JLabel
s are null), use the
builder's addToIcons(JLabel)
.
