Strange problem with QPushButton

[timarco]

Hello,

Firstly, I apologize for my english.

I have a strange problem. It's verry dificult to explain so i hope that you understand me (I do my best). I develop my application which have some QPushButton. When I go on my first button I can click on him. No problem. But when i go on my second button, if it's not align vertically with the first button, I can't click on him. It's more stranger because on the third button, i don't have this problem. Anyone have already this problem? I put my code.

#include <QApplication>
#include <QObject>
#include "MaFenetre.h"

Can it be that a label covers the button that dont work ?
Labels are transparent and it would not be visible.

@timarco
as @mrjj siad, and I find that m_line_sechantillon_file( QLineEdit ) and m_text_mes_sechantillon( QLabel ) overlap m_bouton_schantillon( QPushButton )

and why not use layout to handle widgets' position?
