That's ok, if I check the xml I can see the correct source:

Qt Code: 
  1. <widget class="QLabel" name="label_2">
  2.     <property name="geometry">
  3.      <rect>
  4.       <x>190</x>
  5.       <y>150</y>
  6.       <width>57</width>
  7.       <height>14</height>
  8.      </rect>
  9.     </property>
  10.     <property name="text">
  11.      <string>TextLabel</string>
  12.     </property>
  13.    </widget>
  14.   </widget>
To copy to clipboard, switch view to plain text mode 

And in the .cpp file it is put:
Qt Code: 
  1. #include "ui_mainwindow.h"
To copy to clipboard, switch view to plain text mode 

But in the terminal if I do qmake, make, ./nameproyect I can see the correct changes.
This problem don't happen in all my proyects.

Thanks
