Message dialogs

There are two ways to create simple messages dialogs:

• Using the GUI application which has several methods to directly show message dialogs
• Using the MDIMessageDialogHelper class which allow to create messages dialogs without having to use an instance of the GUIApplication

Using the GUI application

Several GUI application methods allow to add simple message dialogs:

• The GUIApplication.showMessageDialog(String, int, boolean, boolean, String...) method allow to add an OK message dialog, showing optionally an icon for the type of the dialog, and specifying if the dialog is modal and resizable
• The GUIApplication.showMessageDialog(String, int, String...) method allow to add an OK message dialog, showing optionally an icon for the type of the dialog, which is modal and not resizable
• The GUIApplication.showMessageDialog(String, String...) method allow to add an OK message dialog, without an icon, which is modal and not resizable

In all the cases the messages argument specifies the array of messages which will be shown in the dialog, organized in a vertical grid.

Example

The following example creates a message dialog presenting the width and height of an image:

   public class AnalyzeImageAction extends AbstractMDIAction {
      public AnalyzeImageAction(MDIApplication appli, String name) {
        super(appli, name);
        this.setDescription("Analyze", "Analyze Image");
      }

      @Override
      public void run() throws Exception {
        GUIApplication gui = ((GUIApplication) app);
        BufferedImage image = (BufferedImage) gui.getSelectedProperties().getObject();
        gui.showMessageDialog("Size", MDIDialogBuilder.INFORMATION_MESSAGE, "Width: " + image.getWidth(), "Height: " + image.getHeight());
      }
   }

with the following result:

Using the MDIMessageDialogHelper class

Several static methods of the MDIMessageDialogHelper class allow to add simple message dialogs:

• The MDIMessageDialogHelper.showMessageDialog(String, int, boolean, boolean, String...) method allow to add an OK message dialog, showing optionally an icon for the type of the dialog, and specifying if the dialog is modal and resizable
• The MDIMessageDialogHelper.showMessageDialog(String, int, String...) method allow to add an OK message dialog, showing optionally an icon for the type of the dialog, which is modal and not resizable
• The MDIMessageDialogHelper.showMessageDialog(String, String...) method allow to add an OK message dialog, without an icon, which is modal and not resizable

As you can see, you don"t need an instance of the GUIApplication to execute these methods^[1]

The GUI application instance is provided to this class at the start of the framework

.

Example

The following example creates a message dialog presenting the width and height of an image, using the MDIMessageDialogHelper:

   public class AnalyzeImageAction extends AbstractMDIAction {
      public AnalyzeImageAction(MDIApplication appli, String name) {
        super(appli, name);
        this.setDescription("Analyze", "Analyze Image");
      }

      @Override
      public void run() throws Exception {
        GUIApplication gui = ((GUIApplication) app);
        BufferedImage image = (BufferedImage) gui.getSelectedProperties().getObject();
        MDIMessageDialogHelper.showMessageDialog("Size", MDIDialogBuilder.INFORMATION_MESSAGE, "Width: " + image.getWidth(), "Height: " + image.getHeight());
      }
   }

with the following result:
