Hi,

i try to use a ComboBox for a selection of Baudrates.
I wan't to Display the Label for a Baudrate and store an unisigned int in the userData.

Here's my Code:
Qt Code: 
  1. typedef struct
  2. {
  3.     QString         m_displayName;
  4.     unsigned int    m_Btr0Btr1;
  5. } baudrate_t;
  6.  
  7. ...
  8.  
  9. const baudrate_t available_bauds[]={  {"1 MBaud/s",0x014},
  10.                                         {"800 kBaud/s",0x0016},
  11.                                         {"500 kBaud/s",0x001C},
  12.                                         {"250 kBaud/s",0x011C},
  13.                                         {"125 kBaud/s",0x031C},
  14.                                         {"100 kBaud/s",0x432F},
  15.                                         {"95 kBaud/s",0xC34E},
  16.                                         {"83 kBaud/s",0x852B},
  17.                                         {"50 kBaud/s",0x472F},
  18.                                         {"47 kBaud/s",0x1414},
  19.                                         {"33 kBaud/s",0x8B2F},
  20.                                         {"20 kBaud/s",0x532F},
  21.                                         {"10 kBaud/s",0x672F},
  22.                                         {"5 kBaud/s",0x7F7F},
  23.                                      };
  24.  
  25. ...
  26.  
  27. for (int i = 0; i<( sizeof(available_bauds) / sizeof(available_bauds[0]) ); ++i)
  28.     {
  29.         QString       Label    = available_bauds[i].m_displayName;
  30.         unsigned int  BTR0BTR1 = available_bauds[i].m_Btr0Btr1;
  31.         ui->cB_baudrate->addItem(Label,QVariant(BTR0BTR1));
  32.     }
  33.  
  34. /*DEBUG Code*/
  35.     qDebug() << ui->cB_baudrate->itemText(2);
  36.     QVariant check_data =  ui->cB_baudrate->itemData(2,Qt::UserRole);
  37.     bool ok = false;
  38.     unsigned int check_btr0btr1 = check_data.toUInt(&ok);
  39.     if (ok)
  40.     {
  41.         qDebug() << check_btr0btr1;
  42.     }
  43. /*END DEBUG CODE*/
To copy to clipboard, switch view to plain text mode 

the returned QVariant is always invalid.

What am i doing wrong?
