```
public static final int PARENTSIZEMIN
```
    Constant used in param width or height (will use parent's minimum size between width and height) in setRect. You can use this constant added or subtracted to a number to specify a increment to the calculated size. There are two ways to use it:
    1. PARENTSIZEMIN + constant: it will use as a PERCENTAGE of the parent's size. For example, PARENTSIZEMIN+20 in width will result in 20% of parent's size.
    2. PARENTSIZEMIN - constant: it will use as a FRACTION of the parent's size. For example, PARENTSIZEMIN-4 in width will result in 1/4 of parent's size.
    If there are no constant number, size will be 100% of the parent's width/height. If the parent is unknown, the screen size will be used instead.

You can set pass BRIGHTER_BACKGROUND or DARKER_BACKGROUND as parameter, AFTER calling setBackColor or setForeColor, to compute the color based on the background.

  - addTimer
```
public TimerEvent addTimer(int millis)
```
    Adds a timer to a control. Each time the timer ticks, a TIMER event will be posted to the control. The timer does not interrupt the program during its execution at the timer interval, it is scheduled along with application events. The timer object returned from this method can be passed to removeTimer() to remove the timer. Under Windows, the timer has a minimum resolution of 55ms due to the native Windows system clock resolution of 55ms. Under Palm OS and other platforms, the minimum timer resolution is 10ms.
    If the control that holds the timer is removed from screen, the timer is also disabled. Consider using the dispatch-listener event model (addTimerListener) instead of creating a control just to catch the event (if this is the case).
    
    Parameters:
    
    millis - the timer tick interval in milliseconds

```
    The relative positioning will be made with the given control (relative). Note that in this case, only the SAME,BEFORE,AFTER are affected by the given control. Here is an example of relative positioning:
    Important note: you can't use FILL/FIT with BEFORE/RIGHT/BOTTOM (for x,y).
    add(new Label("1"),CENTER,CENTER); add(new Label("2"),AFTER,SAME); add(new Label("3"),SAME,AFTER); add(new Label("4"),BEFORE,SAME); add(new Label("5"),BEFORE,BEFORE);
    You will see this on screen:
    512 43
    Note: add(control, x,y) does: add(control); control.setRect(x,y,PREFERRED,PREFERRED);
    Important! Always add the control to the container before doing a setRect.
    The relative positioning does not work well if the control is placed outside screen bounds.
    Parameters:
    
    x - One of the relative positioning constants: LEFT, RIGHT, SAME, BEFORE, AFTER, CENTER, with a small adjustment. You can also use an absolute value, but this is strongly discouraged.
    
    y - One of the relative positioning constants: TOP, BOTTOM, SAME, BEFORE, AFTER, CENTER, with a small adjustment. You can also use an absolute value, but this is strongly discouraged.
    
    width - One of the relative positioning constants: PREFERRED, FILL, FIT, SAME. You can also use an absolute value, but this is strongly discouraged.
    
    height - One of the relative positioning constants: PREFERRED, FILL, FIT, SAME. You can also use an absolute value, but this is strongly discouraged.
    
    relative - To whom the position should be relative to; or null to be relative to the last control.
    
    screenChanged - Indicates that a screen change (resize, collapse) occured and the reposition method is calling this method. Set by the system. If you call this method directly, always pass false to it.

  - repaint
```
public static void repaint()
```
    Marks all controls in the screen for repaint. Important note: when you call repaint, a flag is set indicating that the screen must be repainted; then, the next time a event (a keypress, a timer, a pen event) occurs, the screen is updated. If you call repaint and the control isn't effectively repainted, you can use the Control.repaintNow method.
    
    If you want to avoid a method call, you can do
    Window.needsPaint = true;
    See Also:

    Redraws the control immediately. If this control is a Window, the whole window area is marked for repaint (useful if you're removing some controls from a container). This method affects only this control, while the repaint method affects the whole screen. If Window.enableUpdateScreen is true, the method returns immediately.

public void setFocusLess(boolean on)
```
    Sets this control to be focusless. If this control is a container, sets all its children to be focusless too. A focusless control can receive and dispatch events, but cannot receive focus. Here's an example of how to use it to create a keypad:
    // class fields private PushButtonGroup numericPad; private KeyEvent ke = new KeyEvent(); // in the initUI method: String []numerics = {"1","2","3","4","5","6","7","8","9","0",".","-"}; add(numericPad=new PushButtonGroup(numerics, false, -1, -1, 6, 4, true, PushButtonGroup.BUTTON), RIGHT-2, TOP+2); numericPad.setFocusLess(true); // in the onEvent method Control focus; if (e.target == numericPad && (focus=getParentWindow().getFocus()) instanceof Edit) { String s = numericPad.getSelectedCaption(); if (s != null) { ke.key = s.charAt(0); ke.target = focus; focus.onEvent(ke); } }

  - updateScreen
```
public static void updateScreen()
```
    This method causes the immediate screen update. The screen is saved in a buffer and, when this method is called, the buffer is transfered to the screen, using the nextTransitionEffect set. NOTE: for a thread-safe version, use safeUpdateScreen
