All Implemented Interfaces:

Drawable
```
public class CTabFolder
extends Composite
```
Instances of this class implement the notebook user interface metaphor. It allows the user to select a notebook page from set of pages.
The item children that may be added to instances of this class must be of type CTabItem. Control children are created and then set into a tab item using CTabItem#setControl.
Note that although this class is a subclass of Composite, it does not make sense to set a layout on it.

Styles:

CLOSE, TOP, BOTTOM, FLAT, BORDER, SINGLE, MULTI

Events:

Selection

"CTabFolder2"

Note: Only one of the styles TOP and BOTTOM may be specified.
IMPORTANT: This class is not intended to be subclassed.

```
public CTabFolder(Composite parent,
          int style)
```
    Constructs a new instance of this class given its parent and a style value describing its behavior and appearance.
    The style value is either one of the style constants defined in class SWT which is applicable to instances of this class, or must be built by bitwise OR'ing together (that is, using the int "|" operator) two or more of those SWT style constants. The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses.
    Parameters:
    parent - a widget which will be the parent of the new instance (cannot be null)
    style - the style of widget to construct
    
    Throws:
    java.lang.IllegalArgumentException -
    
    ERROR_NULL_ARGUMENT - if the parent is null

```
    Description copied from class: Scrollable
    
    Given a desired client area for the receiver (as described by the arguments), returns the bounding rectangle which would be required to produce that client area.
    In other words, it returns a rectangle such that, if the receiver's bounds were set to that rectangle, the area of the receiver which is capable of displaying data (that is, not covered by the "trimmings") would be the rectangle described by the arguments (relative to the receiver's parent).

    Parameters:
    x - the desired x coordinate of the client area
    y - the desired y coordinate of the client area
    width - the desired width of the client area
    height - the desired height of the client area
    
    Returns:
    the required bounds to produce the given client area

  - getMRUVisible
```
public boolean getMRUVisible()
```
    Returns true if the receiver displays most recently used tabs and false otherwise.
    When there is not enough horizontal space to show all the tabs, by default, tabs are shown sequentially from left to right in order of their index. When the MRU visibility is turned on, the tabs that are visible will be the tabs most recently selected. Tabs will still maintain their left to right order based on index but only the most recently selected tabs are visible.
    For example, consider a CTabFolder that contains "Tab 1", "Tab 2", "Tab 3" and "Tab 4" (in order by index). The user selects "Tab 1" and then "Tab 3". If the CTabFolder is now compressed so that only two tabs are visible, by default, "Tab 2" and "Tab 3" will be shown ("Tab 3" since it is currently selected and "Tab 2" because it is the previous item in index order). If MRU visibility is enabled, the two visible tabs will be "Tab 1" and "Tab 3" (in that order from left to right).

  - reskin
```
public void reskin(int flags)
```
    Description copied from class: Widget
    
    Marks the widget to be skinned.
    The skin event is sent to the receiver's display when appropriate (usually before the next event is handled). Widgets are automatically marked for skinning upon creation as well as when its skin id or class changes. The skin id and/or class can be changed by calling Display.setData(String, Object) with the keys SWT.SKIN_ID and/or SWT.SKIN_CLASS. Once the skin event is sent to a widget, it will not be sent again unless reskin(int) is called on the widget or on an ancestor while specifying the SWT.ALL flag.
    
    The parameter flags may be either:
    
    SWT.ALL
    
    all children in the receiver's widget tree should be skinned
    
    SWT.NONE
    
    only the receiver should be skinned
    
    Overrides:
    
    reskin in class Widget
    
    Parameters:
    flags - the flags specifying how to reskin
  - setBackground
```
public void setBackground(Color color)
```
    Description copied from class: Control
    
    Sets the receiver's background color to the color specified by the argument, or to the default system color for the control if the argument is null.
    Note: This operation is a hint and may be overridden by the platform. For example, on Windows the background of a Button cannot be changed.
    
    Overrides:
    
    setBackground in class Control
    
    Parameters:
    color - the new color (or null)
  - setBackground
```
public void setBackground(Color[] colors,
                 int[] percents)
```
    Specify a gradient of colors to be drawn in the background of the unselected tabs. For example to draw a gradient that varies from dark blue to blue and then to white, use the following call to setBackground:
```
        cfolder.setBackground(new Color[]{display.getSystemColor(SWT.COLOR_DARK_BLUE), 
                                           display.getSystemColor(SWT.COLOR_BLUE),
                                           display.getSystemColor(SWT.COLOR_WHITE), 
                                           display.getSystemColor(SWT.COLOR_WHITE)},
                               new int[] {25, 50, 100});
 
```
    Parameters:
    colors - an array of Color that specifies the colors to appear in the gradient in order of appearance left to right. The value null clears the background gradient. The value null can be used inside the array of Color to specify the background color.
    percents - an array of integers between 0 and 100 specifying the percent of the width of the widget at which the color should change. The size of the percents array must be one less than the size of the colors array.

                                  new int[] {25, 50, 100}, true);
 
```
    Parameters:
    colors - an array of Color that specifies the colors to appear in the gradient in order of appearance left to right. The value null clears the background gradient. The value null can be used inside the array of Color to specify the background color.

  - setMRUVisible
```
public void setMRUVisible(boolean show)
```
    When there is not enough horizontal space to show all the tabs, by default, tabs are shown sequentially from left to right in order of their index. When the MRU visibility is turned on, the tabs that are visible will be the tabs most recently selected. Tabs will still maintain their left to right order based on index but only the most recently selected tabs are visible.
    For example, consider a CTabFolder that contains "Tab 1", "Tab 2", "Tab 3" and "Tab 4" (in order by index). The user selects "Tab 1" and then "Tab 3". If the CTabFolder is now compressed so that only two tabs are visible, by default, "Tab 2" and "Tab 3" will be shown ("Tab 3" since it is currently selected and "Tab 2" because it is the previous item in index order). If MRU visibility is enabled, the two visible tabs will be "Tab 1" and "Tab 3" (in that order from left to right).
    Parameters:
    show - the new visibility state
