Constructor Detail

ProgressBar

public ProgressBar(int canvasWidth,
                   int canvasHeight)

This constructor is called once by ImageJ at startup.

Method Detail

show

public void show(double progress)

Updates the progress bar, where abs(progress) should run from 0 to 1. If abs(progress) == 1 the bar is erased. The bar is updated only if more than 90 ms have passed since the last call. Does nothing if the ImageJ window is not present.

Parameters:

progress - Length of the progress bar to display (0...1). Using progress with negative sign (0 .. -1) will regard subsequent calls with positive argument as sub-ordinate processes that are displayed as moving dot.

show

public void show(double progress,
                 boolean showInBatchMode)

Updates the progress bar, where abs(progress) should run from 0 to 1.

Parameters:

progress - Length of the progress bar to display (0...1).

showInBatchMode - show progress bar in batch mode macros?

show

public void show(int currentIndex,
                 int finalIndex)

Updates the progress bar, where the length of the bar is set to ((abs(currentIndex)+1)/abs(finalIndex) of the maximum bar length. Use a negative currentIndex to show subsequent plugin calls as moving dot. The bar is erased if currentIndex>=finalIndex-1 or finalIndex == 0.

update

public void update(Graphics g)

Overrides:

update in class Canvas

paint

public void paint(Graphics g)

Overrides:

paint in class Canvas

getPreferredSize

public Dimension getPreferredSize()

Overrides:

getPreferredSize in class Component

setBatchMode

public void setBatchMode(boolean batchMode)
