Field Detail

APP_NAME

public static final String APP_NAME
The name of this application, jiuawt, plus the version number taken from JiuInfo. Example: jiuawt 0.8.0. Will be displayed in the title bar of this frame.

Constructor Detail

JiuAwtFrame

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(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 ActionListener
Parameters:
e - the ActionEvent object

componentHidden

public void componentHidden(ComponentEvent e)
Specified by:
componentHidden in interface ComponentListener

componentMoved

public void componentMoved(ComponentEvent e)
Specified by:
componentMoved in interface ComponentListener

componentResized

public void componentResized(ComponentEvent e)
Specified by:
componentResized in interface ComponentListener

componentShown

public void componentShown(ComponentEvent e)
Specified by:
componentShown in interface 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(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(String text)

setWaitCursor

public void setWaitCursor()

showInfo

public void showInfo(String title,
                     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.
