Using canvas to display pictures at open event handler, More than one picture i mean and i do not want any action taken by user but the user get to see the pictures. Any example of such with xojo? The one i see with xojo is by a click on the picture.
Use a timer instead of the button.
Drag a Timer Object into the Editor and add the Timer Action Event. Set the Period of the Timer. In the Action Event you can handle the change of the Picture which will be displayed in the Canvas.
