public abstract class Inspector
extends javax.swing.JPanel

An Inspector is a JPanel containing information about some object, and updates its displayed information when updateInspector() is called. In-between calls to updateInspector(), the Inspector should show the same information despite repeated repaints() etc. Inspectors commonly also allow the user to change the information, but this is not required: they can be "read-only" if desired.

If your inspector is not volatile (it doesn't change frame-to-frame) then you should setInspectorVolatile(false). It's more efficient.

Your inspector should also update itself at time or when otherwise attached to the object it's supposed to inspect. Generally speaking, a non-volatile inspector never has its updateInspector method called except manually (via the button created in makeUpdateButton() for example). If you like, you can simply call updateInspector() in your own constructor.

`void` | `setVolatile(boolean val)` Set to true (default) if the inspector should be updated every time step.
`protected void` | `updateButtonPressed()` If you've added an UpdateButton with makeUpdateButton(), it will call updateButtonPressed when it is pressed, which by default will call updateInspector().

Field Detail

### UPDATE_ICON

    public static final javax.swing.ImageIcon UPDATE_ICON

Constructor Detail

### Inspector

    public Inspector()

Method Detail

### setVolatile

    public void setVolatile(boolean val)

  Set to true (default) if the inspector should be updated every time step. Else set to false.

### isVolatile

    public boolean isVolatile()

  Returns true (default) if the inspector should be updated every time step. Else returns false.

### updateInspector

    public abstract void updateInspector()

### getUpdateSteppable

    public Steppable getUpdateSteppable()

### updateButtonPressed

    protected void updateButtonPressed()

  If you've added an UpdateButton with makeUpdateButton(), it will call updateButtonPressed when it is pressed, which by default will call updateInspector(). Override this method if that's not the behavior you want.

### makeUpdateButton

    public java.awt.Component makeUpdateButton()

  A convenient function to create UpdateButton which you might add to the bottom of the JPanel (assuming it still is using BorderLayout). This is helpful for the user if your inspector isn't volatile.
