DisplayWindow

All Superinterfaces:

java.lang.AutoCloseable, java.io.Closeable, DataViewer, EventPublisher
```
public interface DisplayWindow
extends DataViewer, java.io.Closeable
```
A DisplayWindow is the interface to Micro-Manager's image display windows. It is not expected that third-party code implement this interface. If you want to provide your own custom display then you should implement DataViewer instead.

- Method Detail
  - displayStatusString
```
void displayStatusString(java.lang.String status)
```
    Display a custom string in the window. The string will remain displayed until this method is called again to change it. Calls are ignored if the display has closed. This method can be called from any thread.
    
    Parameters:
    
    status - String to display in the window.
  - getZoom
```
double getZoom()
```
    Get the current zoom ratio of the display. If the display has closed, the returned value is undefined. This method can be called from any thread. However, you should call it from the Swing/AWT event dispatch thread if you want to correctly synchronize with other user interface changes.
    
    Returns:
    
    the current zoom ratio (1.0 = actual size)
  - getMagnification
```
@Deprecated
double getMagnification()
```
    Deprecated. use getZoom() instead
    
    Obsolete equivalent of getZoom().
    
    Returns:
    
    the current zoom level
  - setZoom
```
void setZoom(double ratio)
```
    Set the zoom ratio for this display. Calls are ignored if the display has closed. This method can be called from any thread. However, you should call it from the Swing/AWT event dispatch thread if you want to correctly synchronize with other user interface changes.
    
    Parameters:
    
    ratio - zoom ratio to set (1.0 = actual size)
  - setMagnification
```
@Deprecated
void setMagnification(double ratio)
```
    Deprecated. use setZoom(double) instead
    
    Obsolete equivalent of setZoom(double).
    
    Parameters:
    
    ratio -
  - adjustZoom
```
void adjustZoom(double factor)
```
    Multiply the current zoom ratio of the image canvas by the provided factor. This is equivalent to setZoom(factor * getZoom()) if called on the Swing/AWT event dispatch thread. Calls are ignored if the display has closed. This method can be called from any thread. However, you should call it from the Swing/AWT event dispatch thread if you want to correctly synchronize with other user interface changes.
    
    Parameters:
    
    factor - the factor to zoom in by
  - autostretch
```
void autostretch()
```
    Perform a one-shot autoscaling of intensities. The intensity range of the currently displayed image is used to set the intensity scaling range for all displayed channels. If continuous autostretching was enabled, it is disabled. Calls are ignored if the display has closed. This method can be called from any thread. However, you should call it from the Swing/AWT event dispatch thread if you want to correctly synchronize with other user interface changes.
  - addOverlay
```
void addOverlay(Overlay overlay)
```
    Add a graphical overlay. This method can be called from any thread. However, you should call it from the Swing/AWT event dispatch thread if you want to correctly synchronize with other user interface changes.
    
    Parameters:
    
    overlay - the overlay to add
    
    Throws:
    
    java.lang.NullPointerException - if overlay is null

    removeOverlay(org.micromanager.display.overlay.Overlay), getOverlays()
  - removeOverlay
```
void removeOverlay(Overlay overlay)
```
    Remove a graphical overlay. This method can be called from any thread. However, you should call it from the Swing/AWT event dispatch thread if you want to correctly synchronize with other user interface changes.
    
    Parameters:
    
    overlay - the overlay to remove
    
    See Also:
    
    addOverlay(org.micromanager.display.overlay.Overlay)
  - getOverlays
```
java.util.List<Overlay> getOverlays()
```
    Get the overlays attached to this display. This method can be called from any thread. However, you should call it from the Swing/AWT event dispatch thread if you want to correctly synchronize with other user interface changes.
    
    Returns:
    
    the overlays
    
    See Also:
    
    addOverlay(org.micromanager.display.overlay.Overlay)
  - getImagePlus
```
@Deprecated
ij.ImagePlus getImagePlus()
```
    Deprecated. Directly accessing the ImagePlus of an MMStudio display window will generally result in very fragile code. Consider accessing image data through DataViewer.getDataProvider(). For drawing overlay graphics, see addOverlay(org.micromanager.display.overlay.Overlay).
    
    Return the ImageJ ImagePlus object used by the display window. Note that the ImagePlus may be replaced with a new one during the lifetime of the display window. It is recommended that this method be called on the Swing/AWT event dispatch thread. If you call it from another thread, make sure that your thread is not obstructing the event dispatch thread (i.e. the event dispatch thread is not waiting for your thread to finish something).
    
    Returns:
    
    the ImagePlus used by the window, which may be a CompositeImage, or null if none has been created or if the display has closed.
  - requestToClose
```
boolean requestToClose()
```
    Close this display window, giving its owner a chance to cancel closing. For example, the owner may prompt the user to save the data associated with this display. Special display windows may perform other actions. Calls are ignored if the display has already closed.
    
    Returns:
    
    true if the display is closed, or was already closed; false if it remains open
  - close
```
void close()
```
    Close this display window unconditionally. This will skip such actions as prompting the user to save the data. Special display windows may skip other special actions. Calls are ignored if the display has already closed. This method can be called from any thread. However, you should call it from the Swing/AWT event dispatch thread if you want to correctly synchronize with other user interface changes. In particular, the display may not have closed yet at the moment this method returns if called on another thread.
    
    Specified by:
    
    close in interface java.lang.AutoCloseable
    
    Specified by:
    
    close in interface java.io.Closeable
  - setFullScreen
```
void setFullScreen(boolean enable)
```
    Enable or disable full screen mode. Calls are ignored if the display has closed. This method can be called from any thread. However, you should call it from the Swing/AWT event dispatch thread if you want to correctly synchronize with other user interface changes.
    
    Parameters:
    
    enable - whether to enable or disable full screen mode
  - isFullScreen
```
boolean isFullScreen()
```
    Tell whether full screen mode is currently enabled. It is recommended that this method be called on the Swing/AWT event dispatch thread. If you call it from another thread, make sure that your thread is not obstructing the event dispatch thread (i.e. the event dispatch thread is not waiting for your thread to finish something).
    
    Returns:
    
    whether full screen mode is enabled (false if the display has closed
  - toggleFullScreen
```
@Deprecated
void toggleFullScreen()
```
    Deprecated. use setFullScreen(boolean) instead
    
    Enable or disable full screen mode. Calls are ignored if the display has closed.
  - duplicate
```
DisplayWindow duplicate()
```
    Create a new display window for the same data provider as this one. This method can be called from any thread. However, you should call it from the Swing/AWT event dispatch thread if you want to correctly synchronize with other user interface changes.
    
    Returns:
    
    the new display window
  - toFront
```
void toFront()
```
    Raise this display window to the front. Calls are ignored if the display has closed. This method can be called from any thread. However, you should call it from the Swing/AWT event dispatch thread if you want to correctly synchronize with other user interface changes.
  - getWindow
```
java.awt.Window getWindow()
                   throws java.lang.IllegalStateException
```
    Get the java.awt.Window used for this image display. You should not access the contents of the returned window, but you can set its on-screen position and size, etc. If the display is in full screen mode, this method returns the original (hidden) window, not the window used for full-screen display. It is recommended that this method be called on the Swing/AWT event dispatch thread. If you call it from another thread, make sure that your thread is not obstructing the event dispatch thread (i.e. the event dispatch thread is not waiting for your thread to finish something).
    
    Returns:
    
    the java.awt.Window used by this image display
    
    Throws:
    
    java.lang.IllegalStateException - if the display has closed
  - getAsWindow
```
@Deprecated
java.awt.Window getAsWindow()
```
    Deprecated. use getWindow() instead
    
    Get the java.awt.Window used for this image display.
    
    Returns:
    
    the java.awt.Window used by this image display, or null if the display has been closed
  - setCustomTitle
```
void setCustomTitle(java.lang.String title)
```
    Add a custom extra string to the title of this display. The usual format for the window title is "#number: name (zoom ratio) (saved status)". If you call this method, then the name part will be replaced by your custom title. You can call this method with a null argument to revert to the default title, which is what DataViewer.getName() returns. Calls are ignored if the display has closed. This method can be called from any thread.
    
    Parameters:
    
    title - a custom window title, or null to revert to the default
  - show
```
void show()
```
    DisplayWindows are not shown by default. Call this function after construction, and after attaching listeners as needed, to show the Window.
