Using PopUp...

Well, the simple way to learn it is to study TheIDE code... (ide/Help.cpp around line 90) Wink

Thank for suggestion.

I have found the (complex) solution from IDE code and I have simplified it.
The key to show a splash screen is "Ctrl::ProcessEvent();".

This is the code which works:

GUI_APP_MAIN

{
HelloWorld hw;//Examples: AnimatedHello
hw.PopUp(NULL,false,false,true,true);

Ctrl::ProcessEvent();

MyAppWindow app;

Ctrl::EventLoop(); //to run animation

app.Run();
}

Hello Andrei,

thank you for the code snippet. I needed it too. I've modified it slightly to see it in action

GUI_APP_MAIN
{ TopWindow app;

  HelloWorld hw;//Examples: AnimatedHello 
  hw.PopUp(NULL,false,false,true,true);
  hw.Title("Hello world example");
  hw.Text(Nvl(Join(CommandLine(), " "), "Hello world !"));

  Ctrl::ProcessEvent();
  Ctrl::EventLoop(); //to run animation
  app.Run();
}

where this block should substitude the one in AnimatedHello package.
Now next problem is to let appear some static image for a given amount of time. Have you another code snippet with the solution? Smile

Hello, Luigi!

In my computer the "freezing" is indistinguishable.
However, between hw.PopUp() and Ctrl::EventLoop() lines is no animation.
Changing the order of lines should attenuate this undesirable effect.
Using a static image is more safe (although this is less spectacular).

GUI_APP_MAIN
{
TopWindow app;
HelloWorld hw;
//hw.Title("Hello world example");//not necessary
hw.Text(Nvl(Join(CommandLine(), " "), "Hello world !"));
hw.PopUp(NULL,false,false,true,true);
//Ctrl::ProcessEvent();//not ncessary
Ctrl::EventLoop();//to run animation

app.Run();

}
