AutoSizingBase (gwt-traction 1.6.0 API)

java.lang.Object
- com.google.gwt.user.client.ui.UIObject
- - com.google.gwt.user.client.ui.Widget
  - - com.google.gwt.user.client.ui.Composite
    - - com.tractionsoftware.gwt.user.client.ui.AutoSizingBase<T,S>

All Implemented Interfaces:

KeyDownHandler, KeyUpHandler, HasAttachHandlers, ValueChangeHandler<String>, EventHandler, HasHandlers, EventListener, Focusable, HasText, HasVisibility, IsRenderable, IsWidget

Direct Known Subclasses:

AutoSizingTextArea, AutoSizingTextBox
```
public abstract class AutoSizingBase<T extends Widget & HasTextSelection & HasValue<String> & HasValueChangeHandlers<String> & HasKeyDownHandlers & HasKeyUpHandlers & Focusable & HasText,S extends Widget>
extends Composite
implements KeyDownHandler, KeyUpHandler, ValueChangeHandler<String>, Focusable, HasText
```
This attaches to an input, listening for KeyDown/KeyUp, and automatically resizing the text area. It does this using a shadow control that matches the text of the input.

Constructor Detail

AutoSizingBase

public AutoSizingBase(T box,
              S shadow)

Method Detail
- getShadowSize
```
public abstract int getShadowSize()
```
  Returns the size of the shadow element
- setShadowText
```
public abstract void setShadowText(String text)
```
  Parameters:
  text - the text that should be set on the shadow to determine the appropriate size of the widget
- setSize
```
public abstract void setSize(int size)
```
  Parameters:
  size - will take into account minSize, maxSize, and extraSize. the implementation should just call setWidth or setHeight as appropriate.
- getMinSize
```
public final int getMinSize()
```
- setMinSize
```
public final void setMinSize(int minSize)
```
- getMaxSize
```
public final int getMaxSize()
```
- setMaxSize
```
public final void setMaxSize(int maxSize)
```
- getExtraSize
```
public final int getExtraSize()
```
  This is the amount of extra horizontal or vertical space that will be added.
- setExtraSize
```
public final void setExtraSize(int extraSize)
```
- setMinFromCss
```
public final void setMinFromCss(String property)
```
- setMaxFromCss
```
public final void setMaxFromCss(String property)
```
- getAndResetValueFromCss
```
public final int getAndResetValueFromCss(String property,
                          String reset)
```
- onLoad
```
protected void onLoad()
```
  Matches the styles and adjusts the size. This needs to be called after the input is added to the DOM, so we do it in onLoad.
  
  Overrides:
  
  onLoad in class Widget
- getWidget
```
public T getWidget()
```
  Overrides:
  
  getWidget in class Composite
- matchStyles
```
public void matchStyles(String name)
```
- setStyles
```
public void setStyles(String name,
             String value)
```
- onKeyDown
```
public void onKeyDown(KeyDownEvent event)
```
  On key down we assume the key will go at the end. It's the most common case and not that distracting if that's not true.
  
  Specified by:
  
  onKeyDown in interface KeyDownHandler
- onKeyUp
```
public void onKeyUp(KeyUpEvent event)
```
  Specified by:
  
  onKeyUp in interface KeyUpHandler
- onKeyCodeEvent
```
protected void onKeyCodeEvent(KeyCodeEvent event,
                  String newShadowText)
```
- onValueChange
```
public void onValueChange(ValueChangeEvent<String> event)
```
  Specified by:
  
  onValueChange in interface ValueChangeHandler<String>
- sync
```
public void sync()
```
- resetSize
```
public void resetSize()
```
- adjustSize
```
public void adjustSize()
```
- setWidth
```
public void setWidth(int width)
```
- setHeight
```
public void setHeight(int height)
```
- getTabIndex
```
public final int getTabIndex()
```
  Specified by:
  
  getTabIndex in interface Focusable
- setTabIndex
```
public final void setTabIndex(int index)
```
  Specified by:
  
  setTabIndex in interface Focusable
- setFocus
```
public final void setFocus(boolean focus)
```
  Specified by:
  
  setFocus in interface Focusable
- setAccessKey
```
public final void setAccessKey(char key)
```
  Specified by:
  
  setAccessKey in interface Focusable
- getText
```
public final String getText()
```
  Specified by:
  
  getText in interface HasText
- setText
```
public abstract void setText(String text)
```
  Specified by:
  
  setText in interface HasText
