Hi, you need to call the show() method of MainPara.
class MainScreen : public Screen, public ButtonListener
{
public:
MainScreen()
{
mPara = new Parametre();
mButton = new Button();
mButton->setText("Parametre");
mButton->addButtonListener(this);
}
void buttonClicked(Widget* button)
{
mPara->show();
}
};

Sure. Add MainPara.h MainScreen with #include "MainPara.h" and set a MainPara* called mMainPara;

#ifndef MAINSCREEN_H_
#define MAINSCREEN_H_

When I modify as you made him he puts me the following error:
C:\Documents and Settings\cottin\WorkSpace\HouseAlert\/MainScreen.h:51: error: ISO C++ forbids declaration of `MainPara' with no type
C:\Documents and Settings\cottin\WorkSpace\HouseAlert\/MainScreen.h:51: error: expected `;' before '*' token

Did you include this line?
#include "MainPara.h"
