MultiLineLabel in GenericDialog

[Stephan Preibisch]

Hi everyone,

I want to use a MultiLineLabel to display text in a GenericDialog. Using a listener I want to change that comment (the MultiLineLabel) depending on a choice in one of the other elements. However, there is no method to set the text of the MultiLineLabel.

Until now, I used a Label, where after adding the message " " to the GenericDialog, I changed the text which then contains "\n"'s before calling showDialog(). This way I got a Label which has multiple lines and a setText() method that I can call from the Listener. I just recently figured out that this works only under Mac, not Windows and Linux. Bummer.

Is there any way to set the text of a MultiLineLabel without using reflections?
Alternatively, I could use multiple normal Labels, but then the distance between them is far too large, it does not look like a block.

If this all doesn't work, I will extend the MultiLineLabel class and add it as my own element. But if there is a more elegant way would be nice.

Thanks a lot,
Stephan

The latest ImageJ daily build (1.49a19) adds a setText() method to the MultiLineLabel class. The following example plugin, which is recordable, demonstrates how to use this method.

import ij.*;
import ij.plugin.PlugIn;
import ij.gui.*;
import java.awt.*;

public class Dialog_Test implements PlugIn, DialogListener {
    private String divider = "----------";
    private String defaultText = "abcdef";
    private static GenericDialog gd;
    String text;

    public void run(String arg) {
        showDialog();
        IJ.log("Text: "+text);
    }
               
    void showDialog() {
        gd = new GenericDialog("Test Dialog");
        gd.addStringField("Text: ", defaultText);
        gd.addMessage(divider+"\n"+defaultText+"\n"+divider);
        gd.addDialogListener(this);
        gd.showDialog();
    }

    public boolean dialogItemChanged(GenericDialog gd, AWTEvent e) {
        text = gd.getNextString();
        MultiLineLabel label = (MultiLineLabel)gd.getMessage();
        label.setText(divider+"\n"+text+"\n"+divider);
        return true;
    }
   
}
