  - paintChildren
```
public void paintChildren()
```
    Called by the system to draw the children of the container.
  - setBorderStyle
```
public void setBorderStyle(byte border)
```
    Sets the border for this container. The insets are changed after this method is called. The BORDER_ROUNDED sets the background to transparent.
    
    See Also:
    
    BORDER_NONE, BORDER_LOWERED, BORDER_RAISED, BORDER_SIMPLE, BORDER_TOP, BORDER_ROUNDED
  - getClientRect
```
public Rect getClientRect()
```
    Returns the client rect for this Container, in relative coords. The client rectangle usually excludes the title (if applicable) and the border. If you call this method often, consider using the other version, where a cached Rect is used; it avoids the creation of a Rect.
    
    See Also:
    
    getClientRect(Rect)
  - getClientRect
```
protected void getClientRect(Rect r)
```
    Returns the client rect for this Container, in relative coords, excluding the insets. In this version, you provide the instantiated Rect to be filled with the coords.
  - onColorsChanged
```
protected void onColorsChanged(boolean colorsChanged)
```
    Description copied from class: Control
    
    Called after a setEnabled, setForeColor and setBackColor and when a control has been added to a Container. If colorsChanged is true, it was called from setForeColor/setBackColor/Container.add; otherwise, it was called from setEnabled
    
    Overrides:
    
    onColorsChanged in class Control

                              int b)

  - onPaint
```
public void onPaint(Graphics g)
```
    Draws the border (if any). If you override this method, be sure to call super.onPaint(g);, or the border will not be drawn.
    
    Overrides:
    
    onPaint in class Control
    
    Parameters:
    
    g - the graphics object for drawing
    
    See Also:

  - onAddAgain
```
protected void onAddAgain()
```
    When the container is added for the first time, the method initUI is called, so the user interface can be initialized. From the second time and up that the container is added, the onAddAgain method is called instead.
    
    If this container is a window, this method is not called when the window is popped.
    
    If you don't want this method to be called, you must set ignoreOnAddAgain = true; inside the method initUI or the class constructor. Doing so makes the user interface initialize faster.
    
    Since:
    
    SuperWaba 4.1
  - onRemove
```
protected void onRemove()
```
    Called when this container is removed from the parent. Note that, if this container is a window, this method is not called when the window is unpopped.
    
    If you don't want this method to be called, you must set ignoreOnRemove = true; inside the method initUI or the class constructor. Doing so makes the user interface initialize faster.
    
    Since:
    
    SuperWaba 4.1
  - initUI
```
public void initUI()
```
    Called to initialize the User Interface of this container. This differs from the onAddAgain method by that this method is called only once, at the first time the control is added to the parent. When the container is being setup, the initUI method is called; then, the onAddAgain is called every time the container is added again.
    
    Since:
    
    SuperWaba 3.4
  - setHighlighting
```
public void setHighlighting()
```
    Called by the event dispatcher to set highlighting back to true. A class may extend this to decide when its time to turn it on again or not.
  - swapToTopmostWindow
```
public void swapToTopmostWindow()
```
    Call this method to swap this Container to the topmost window. Note that since we have no idea who is our future parent window, we just use the topmost window. The topmost window is the one that is currently visible.
    This method is useful if you have containers that are SINGLETONS and wish to set them as the current container. E.G.:
```
 public class MainMenu extends Container // create a Singleton from MainMenu
 {
    private static instance;
    public static getInstance()
    {
       return instance != null ? instance : (instance=new MainMenu());
    }
    private MainMenu()
    {
    }
  }
  // then at some other class, you can do:
  MainMenu.getInstance().swapToTopmostWindow();
  
```

```
public void getFocusableControls(Vector v)
```
    Get a list of child controls of this container which are focus candidates
    
    Parameters:

```
public Control findNextFocusControl(Control c,
                                    int direction)
```
    Finds the next control that should receive focus based on the direction with respect to c.
    
    Parameters:
    
    c - The reference control from which to find the next control.

    Returns:
    
    The control which should receive focus next, or null.

  - incLastX
```
public void incLastX(int n)

  - resize
```
public void resize()
```
    This method resizes the Container's width and height to the needed bounds, based on added childs. You can add spaces at right and bottom using the insets.right/bottom properties. Sample:
```
   // this sample will center two buttons of different sizes on screen 
   Container c = new Container();
   add(c, CENTER,BOTTOM,1000,1000);
   c.add(new Button("Ok"),LEFT,TOP);
   c.add(new Button("Cancel"),AFTER+5,SAME);
   c.resize();
 
```
    Note: differently of Window.resize, this method does not call setRect again, it only changes the width and height by direct assignment.
