All Implemented Interfaces:: ActionListener, AdjustmentListener, FocusListener, ItemListener, KeyListener, TextListener, WindowListener, ImageObserver, MenuContainer, Serializable, EventListener, Accessible

Direct Known Subclasses:: NonBlockingGenericDialog

public class GenericDialog
extends Dialog
implements ActionListener, TextListener, FocusListener, ItemListener, KeyListener, AdjustmentListener, WindowListener

This class is a customizable modal dialog box. Here is an example GenericDialog with one string field and two numeric fields:

  public class Generic_Dialog_Example implements PlugIn {
    static String title="Example";
    static int width=512,height=512;
    public void run(String arg) {
      GenericDialog gd = new GenericDialog("New Image");
      gd.addStringField("Title: ", title);
      gd.addNumericField("Width: ", width, 0);
      gd.addNumericField("Height: ", height, 0);
      gd.showDialog();
      if (gd.wasCanceled()) return;
      title = gd.getNextString();
      width = (int)gd.getNextNumber();
      height = (int)gd.getNextNumber();
      IJ.newImage(title, "8-bit", width, height, 1);
   }
 }

To work with macros, the first word of each component label must be unique. If this is not the case, add underscores, which will be converted to spaces when the dialog is displayed. For example, change the checkbox labels "Show Quality" and "Show Residue" to "Show_Quality" and "Show_Residue".

    defaultValue - value to be initially displayed
    digits - number of digits to right of decimal point
  - addNumericField
```
public void addNumericField(String label,
                   double defaultValue,

    Parameters:
    label - the label
    defaultValue - value to be initially displayed
    digits - number of digits to right of decimal point
    columns - width of field in characters
    units - a string displayed to the right of the field

  - addCheckbox
```
public void addCheckbox(String label,
               boolean defaultValue)
```
    Adds a checkbox.
    
    Parameters:
    label - the label
    defaultValue - the initial state
  - addPreviewCheckbox
```
public void addPreviewCheckbox(PlugInFilterRunner pfr)
```
    Adds a checkbox labelled "Preview" for "automatic" preview. The reference to this checkbox can be retrieved by getPreviewCheckbox() and it provides the additional method previewRunning for optical feedback while preview is prepared. PlugInFilters can have their "run" method automatically called for preview under the following conditions: - the PlugInFilter must pass a reference to itself (i.e., "this") as an argument to the AddPreviewCheckbox - it must implement the DialogListener interface and set the filter parameters in the dialogItemChanged method. - it must have DIALOG and PREVIEW set in its flags. A previewCheckbox is always off when the filter is started and does not get recorded by the Macro Recorder.
    
    Parameters:
    pfr - A reference to the PlugInFilterRunner calling the PlugInFilter if automatic preview is desired, null otherwise.
  - addPreviewCheckbox
```
public void addPreviewCheckbox(PlugInFilterRunner pfr,
                      String label)
```
    Add the preview checkbox with user-defined label; for details see the addPreviewCheckbox method with standard "Preview" label. Adds the checkbox when the current image is a CompositeImage in "Composite" mode, unlike the one argument version. Note that a GenericDialog can have only one PreviewCheckbox.
  - addCheckboxGroup
```
public void addCheckboxGroup(int rows,
                    int columns,
