Because of this you do not see the title bar. Sheet Window: Available only on MacOS, a sheet window drops down from the parent window. Modal Dialog: A modal dialog box that cannot be moved around the screen by the user. Movable Modal: A modal dialog box with a title bar that the user can use to drag it around the screen. To do this, add a Window to your project and set its Type property in the Inspector to one of these values: In these situations you can use a Modal Window as a dialog box. There will be times when you need a more advanced dialog box, perhaps with additional controls or a more sophisticated layout than what MessageBox and MessageDialog offer. You can also examine the returned object's properties, if necessary. By determining the type of object that was returned, you learn which button the user pressed. You present the customized dialog by calling the ShowModal method of the MessageDialog class.Īfter the user clicks a button, MessageDialog returns a MessageDialogButton object, which is either an ActionButton, CancelButton, or AlternateActionButton. Not all of the icons are displayed on MacOS. In addition, you can set the text of the message, the subordinate explanation, the type of icon shown in the dialog (no icon, Note, Warning, Stop, or Question), and the title. Set to True to show the button.īy default, only the ActionButton is shown, but you can show the others simply by setting their Visible properties to True. This is a little bit more work, but the results are worth it.Ī MessageDialog can have up to three buttons: ActionButton, CancelButton, and AlternateActionButton, which each have these properties:

You need to declare a variable as type MessageDialog, instantiate it, set its properties, and handle the result returned, which tells you which button the user pressed.

However, since MessageDialog is a class, you cannot accomplish all of this with a one line function call. You can also present subordinate explanatory text below the main message. With the MessageDialog class, you can present up to three buttons and control their text and functionality. By taking advantage of the MessageDialog class you can have more sophisticated dialog boxes than are possible with the MessageBox function.
