    • isSelected

      public boolean isSelected()

    • setSelected

      public void setSelected(boolean arg0)
      Flips the selection flag and, on an actual change, fires ItemEvent then ChangeEvent — the fan-out DefaultButtonModel.setSelected performs.

      A plain JButton has no visual selected state, but it very much has the selection state: new JButton("go").setSelected(true) then isSelected() answers true on JDK 25, with an ItemEvent and a ChangeEvent delivered on the way. Only the rendering is missing here, which is the half R_decline_effect_only permits dropping. JToggleButton overrides this to coordinate its ButtonGroup and its surrogate's model (D_jradiobutton).

    • getModel

      public ButtonModel getModel()
      Returns:
      the model setModel(ButtonModel) installed, or null when none was — the button's real state machine is the surrogate's, not reachable through this accessor (SD_sjbutton)

    • setModel

      public void setModel(ButtonModel arg0)
      Installs a user-supplied ButtonModel: getModel() reports it from here on, the JDK's super.setEnabled(model .isEnabled()) propagation runs, and "model" fires. The model itself is inert — the button's state machine lives in the surrogate's own ButtonModel (SD_sjbutton), so a foreign model receives no pressed/armed/selected pulses and drives nothing. That is the declined effect; the state and notification are owed (R_decline_effect_only, D_owed_events).

      The JDK's listener rewiring (ChangeListener / ActionListener / ItemListener onto the new model) is part of the same declined effect, and its updateMnemonicProperties / updateDisplayedMnemonicIndex calls are R_layouts_close_enough rendering.

      getModel() keeps returning null for a button whose model was never set, which is what it did before — so this changes nothing for code that never installs one.
