Good evening, I hope you can help me by get along with addins and c++. Her is my question:

void HelloWorldModule::Draw()
{
	// BeginDraw prevents screen updates until a matching EndDraw
	BeginDraw();

	// Clear the screen
	ClearScreen();
	
	// Draw window border
	DrawFrame();

	// Draw any children objects
	DrawChildren();

	// Draw "Hey" at relative window position (10,10)
	PegColor col;
	PegPoint p = {10,10};
	DrawTextR(p,"Hey",col,PegTextThing::GetBasicFont());

	// Matching EndDraw. If this is the outer layer EndDraw
	// then the screen will be updated.
	EndDraw();
}

This is from HelloWorld.
How can I draw a text, maybe after a buttonclick, later?

I don´t cant edit the window, only when I edit the Draw() sequence.

Hello,

I solved the problem with AddR(new PegPrompt(1, 1, "Text"));

But now my question is, how can I clear the screen?

ClearScreen(); seams to do nothing...

I'm not sure at all as I never programmed a ClassPad, but do you need to update the screen after you clear it?

So:

ClearScreen(); // Clear the screen then right immediately update it
EndDraw(); // And here it is, now update the screen with a blank one
