Running Java based GUIs as Plug In
Locked
 
|
Hello Everyone!
I'm trying to build a user-friendly GUI for a PlugIn. I know that it must be possible, but I looked all over the net and couldn't find a solute answer. The problem that I have is that the PlugIn runs bug-free, and the imageJ status line says "done" without showing the GUI. For example an easy code: import ij.*; import ij.process.*; import ij.gui.*; import java.awt.*; import java.awt.image.*; import java.awt.event.*; import ij.plugin.*; import ij.plugin.frame.*; import java.awt.Color; import javax.swing.*; public class JFrameExample_ { public static void main(String[] args) { JFrame myJFrame = new JFrame(); myJFrame.setTitle("JRadioButton Beispiel"); myJFrame.setSize(450,300); JPanel panel = new JPanel(); panel.setBackground(Color.red); JCheckBox check = new JCheckBox("Ich bin eine CheckBox", true); panel.add(check); myJFrame.add(panel); myJFrame.setLocation(100, 200); myJFrame.pack(); myJFrame.setVisible(true); } } The Compiler runs over it without any trouble, but the GUI is not shown. I saw a lot of PlugIns running with Java GUIs but I couldn't get a single one work! I'm very gladful for every idea. best regards Steve |

Hi Steve,
ImageJ plugins don’t use the standard Java ‘main’ function as an entry point. Try creating a new ImageJ Plugin from « Plugins|New|Plugin » and calling your GUI code from within the provided « run » function. Something like the following: > import ij.*; > import ij.process.*; > import ij.gui.*; > import java.awt.*; > import java.awt.image.*; > import java.awt.event.*; > import ij.plugin.*; > import ij.plugin.frame.*; > import java.awt.Color; > import javax.swing.*; > > public class My_Plugin implements PlugIn { > > public void run(String arg) { > IJ.showMessage("My_Plugin","Hello world!"); > JFrame myJFrame = new JFrame(); > myJFrame.setTitle("JRadioButton Beispiel"); > myJFrame.setSize(450,300); > JPanel panel = new JPanel(); > panel.setBackground(Color.red); > > JCheckBox check = new JCheckBox("Ich bin eine CheckBox", true); > panel.add(check); > > myJFrame.add(panel); > myJFrame.setLocation(100, 200); > myJFrame.pack(); > myJFrame.setVisible(true); > } > } Best regards, John Le 14 oct. 2013 à 15:41, Influenza a écrit : > Hello Everyone! > > I'm trying to build a user-friendly GUI for a PlugIn.

Hi,
On Mon, 14 Oct 2013, John Hayes wrote: > ImageJ plugins don’t use the standard Java ‘main’ function as an entry point. To clarify: main() methods are meant to be main entry points into applications, not into classes. You should expect main() methods to call System.exit() upon exit, which would quit all of ImageJ without giving the user a chance to save their data. That is the reason why plugins have a run() method which is expected *not* to quit the application. ImageJ plugins also have the quirk that you can perform all the computation in a constructor (that cannot take parameters). This is not good object-oriented design, of course, but it is convenient for quick-n-dirty coding. Ciao, Johannes -- ImageJ mailing list: http://imagej.nih.gov/ij/list.html |

Hi Steve;
Guess you are a newbie programming plugins, I was a few months ago :) You don't need a main method. Just implement the necessary interface (PlugIn, PlugInFilter or PlugInFrame), check on the site for more information. In your example the code below should work. public class JFrameExample_ implements PlugIn { public void run(String arg0) { JFrame myJFrame = new JFrame(); myJFrame.setTitle("JRadioButton Beispiel"); myJFrame.setSize(450,300); JPanel panel = new JPanel(); panel.setBackground(Color.red); JCheckBox check = new JCheckBox("Ich bin eine CheckBox", true); panel.add(check); myJFrame.add(panel); myJFrame.setLocation(100, 200); myJFrame.pack(); myJFrame.setVisible(true); } }

Thanks Johannes,
you improved my nooby-knowledge. But do you have an idea how I can run and display the java based GUI? it even doesn't work when I changethe main into a run() method... Best regards Steve |
