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".

public GenericDialog(String title)
```
    Creates a new GenericDialog with the specified title. Uses the current image image window as the parent frame or the ImageJ frame if no image windows are open. Dialog parameters are recorded by ImageJ's command recorder but this requires that the first word of each label be unique.

    defaultText - the text initially displayed
  - addStringField
```
public void addStringField(String label,
                           String defaultText,

  - addCheckbox
```
public void addCheckbox(String label,

```
    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,

    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

```
    Makes the next item appear in the same row as the previous. May be used for addNumericField, addSlider, addChoice, addCheckbox, addStringField, addMessage, addPanel, and before the showDialog() method (in the latter case, the buttons appear to the right of the previous item). Note that addMessage (and addStringField, if its column width is more than 8) use the remaining width, so it must be the last item of a row.
