public JiuAwtFrame(EditorState editorState)
```
    Create an object of this class, using the argument editor state. String resources to initialize the menu etc. will be taken from the EditorState object's Strings variable
    
    Parameters:
    
    editorState - EditorState object used by this frame
- Method Detail
  - actionPerformed
```
public void actionPerformed(java.awt.event.ActionEvent e)
```
    Processes event objects that get created when menu items are picked. Determines the MenuIndexConstants value for a given event object and calls the internal AwtOperationProcessor object's process method with the menu value. The operation will then be performed.
    
    Specified by:
    
    actionPerformed in interface java.awt.event.ActionListener
    
    Parameters:
    
    e - the ActionEvent object
  - componentHidden
```
public void componentHidden(java.awt.event.ComponentEvent e)
```
    Specified by:
    
    componentHidden in interface java.awt.event.ComponentListener
  - componentMoved
```
public void componentMoved(java.awt.event.ComponentEvent e)
```
    Specified by:
    
    componentMoved in interface java.awt.event.ComponentListener
  - componentResized
```
public void componentResized(java.awt.event.ComponentEvent e)
```
    Specified by:
    
    componentResized in interface java.awt.event.ComponentListener
  - componentShown
```
public void componentShown(java.awt.event.ComponentEvent e)
```
    Specified by:
    
    componentShown in interface java.awt.event.ComponentListener
  - maximize
```
public void maximize()
```
    Maximize the frame on the desktop. There is no such function in the 1.1 AWT (was added in 1.4), so this class determines the screen size and sets the frame to be a little smaller than that (to make up for task bars etc.). So this is just a heuristical approach.
  - showError
```
public void showError(java.lang.String text)
```
    Displays the argument text in a message box with error in the title bar.
    
    Parameters:
    
    text - the error message to be displayed
  - setDefaultCursor
```
public void setDefaultCursor()
```
    Sets the current cursor to be Cursor.DEFAULT_CURSOR.
  - setOriginalSize
```
public void setOriginalSize()
```
    If an image is currently loaded,
  - setProgress
```
public void setProgress(int zeroBasedIndex,
                        int totalItems)
```
    Description copied from interface: ProgressListener
    
    Sets a new progress level. If an operation consists of totalItems steps, which are numbered from 0 to totalItems - 1, this method can be called after the completion of each step.
    Example: if there are three steps and the first one is done, the parameters must be 0 and 3, which will indicated 33% completion. Parameters 1 and 3 mean 66%, 2 and 3 100%. If you use 3 and 3, an IllegalArgumentException will be thrown.
    Computes (float)(zeroBasedIndex + 1) / (float)totalItems and calls ProgressListener.setProgress(float) with that value.
    
    Specified by:
    
    setProgress in interface ProgressListener
    
    Parameters:
    
    zeroBasedIndex - the index of the step that was just completed
    
    totalItems - the number of steps in this operation
  - setProgress
```
public void setProgress(float progress)
```
    Set a new progress status.
    
    Specified by:
    
    setProgress in interface ProgressListener
    
    Parameters:
    
    progress - float from 0.0f to 1.0f, indicating the progress between 0 and 100 percent
  - setStatusBar
```
public void setStatusBar(java.lang.String text)
```
  - setWaitCursor
```
public void setWaitCursor()
```
  - showInfo
```
public void showInfo(java.lang.String title,
                     java.lang.String text)
```
    Shows a modal dialog with given title bar and message text.
    
    Parameters:
    
    title - will be displayed in the dialog's title bar
    
    text - will be displayed in the dialog's center part
  - updateCanvas
```
public void updateCanvas()
```
    If there is an image loaded, forces a canvas redraw by calling repaint.
  - updateImage
```
public void updateImage()
```
    Removes the current canvas from the frame (if there is an image loaded) and creates a new canvas for the current image.
  - updateStatusBar
```
public void updateStatusBar()
```
    Creates a description string for the current image and sets the status bar to that text.
  - updateTitle
```
public void updateTitle()
```
    Sets the frame's title bar to the application name, plus the file name of the currently loaded image file, plus the current zoom factor, plus an optional asterisk in case the image was modified but not yet saved.
  - zoomIn
```
public void zoomIn()
```
    If an image is currently displayed, zoom in one level.
  - zoomOut
```
public void zoomOut()
```
    If an image is currently displayed, zoom out one level.
