Hey Guys, I've got a simple pointer question related to QTextEdit. I have 18 QLineEdit boxes. I want to create an Array of QTextEdit pointers to point to the 18 instances of QTextEdit so that I can access them using an index rather then having to call each instance every time. When I do this, however, a runtime error is generated.

The 18 instances of QLineEdit

Qt Code: 
  1. QLineEdit *byte0Edit;
  2.     QLineEdit *byte1Edit;
  3.     QLineEdit *byte2Edit;
  4.     QLineEdit *Byte3Edit;
  5.     QLineEdit *byte6Edit;
  6.     QLineEdit *byte4Edit;
  7.     QLineEdit *byte7Edit;
  8.     QLineEdit *byte5Edit;
  9.     QLineEdit *byte13Edit;
  10.     QLineEdit *byte12Edit;
  11.     QLineEdit *byte10Edit;
  12.     QLineEdit *byte14Edit;
  13.     QLineEdit *byte8Edit;
  14.     QLineEdit *byte11Edit;
  15.     QLineEdit *byte15Edit;
  16.     QLineEdit *byte9Edit;
  17.     QLineEdit *byte16Edit;
  18.     QLineEdit *byte17Edit;
  19.  
  20.     byte0Edit = new QLineEdit(groupBox_2);
  21.     byte0Edit->setObjectName(QString::fromUtf8("byte0Edit"));
  22.     byte0Edit->setGeometry(QRect(177, 40, 31, 20));
  23.     byte1Edit = new QLineEdit(groupBox_2);
  24.     byte1Edit->setObjectName(QString::fromUtf8("byte1Edit"));
  25.     byte1Edit->setGeometry(QRect(217, 40, 31, 20));
  26.     byte2Edit = new QLineEdit(groupBox_2);
  27.     byte2Edit->setObjectName(QString::fromUtf8("byte2Edit"));
  28.     byte2Edit->setGeometry(QRect(257, 40, 31, 20));
  29.     Byte3Edit = new QLineEdit(groupBox_2);
  30.     Byte3Edit->setObjectName(QString::fromUtf8("Byte3Edit"));
  31.     Byte3Edit->setGeometry(QRect(297, 40, 31, 20));
  32.     byte6Edit = new QLineEdit(groupBox_2);
  33.     byte6Edit->setObjectName(QString::fromUtf8("byte6Edit"));
  34.     byte6Edit->setGeometry(QRect(417, 40, 31, 20));
  35.     byte4Edit = new QLineEdit(groupBox_2);
  36.     byte4Edit->setObjectName(QString::fromUtf8("byte4Edit"));
  37.     byte4Edit->setGeometry(QRect(337, 40, 31, 20));
  38.     byte7Edit = new QLineEdit(groupBox_2);
  39.     byte7Edit->setObjectName(QString::fromUtf8("byte7Edit"));
  40.     byte7Edit->setGeometry(QRect(457, 40, 31, 20));
  41.     byte5Edit = new QLineEdit(groupBox_2);
  42.     byte5Edit->setObjectName(QString::fromUtf8("byte5Edit"));
  43.     byte5Edit->setGeometry(QRect(377, 40, 31, 20));
  44.     byte13Edit = new QLineEdit(groupBox_2);
  45.     byte13Edit->setObjectName(QString::fromUtf8("byte13Edit"));
  46.     byte13Edit->setGeometry(QRect(337, 70, 31, 20));
  47.     byte12Edit = new QLineEdit(groupBox_2);
  48.     byte12Edit->setObjectName(QString::fromUtf8("byte12Edit"));
  49.     byte12Edit->setGeometry(QRect(297, 70, 31, 20));
  50.     byte10Edit = new QLineEdit(groupBox_2);
  51.     byte10Edit->setObjectName(QString::fromUtf8("byte10Edit"));
  52.     byte10Edit->setGeometry(QRect(217, 70, 31, 20));
  53.     byte14Edit = new QLineEdit(groupBox_2);
  54.     byte14Edit->setObjectName(QString::fromUtf8("byte14Edit"));
  55.     byte14Edit->setGeometry(QRect(377, 70, 31, 20));
  56.     byte8Edit = new QLineEdit(groupBox_2);
  57.     byte8Edit->setObjectName(QString::fromUtf8("byte8Edit"));
  58.     byte8Edit->setGeometry(QRect(500, 40, 31, 20));
  59.     byte11Edit = new QLineEdit(groupBox_2);
  60.     byte11Edit->setObjectName(QString::fromUtf8("byte11Edit"));
  61.     byte11Edit->setGeometry(QRect(257, 70, 31, 20));
  62.     byte15Edit = new QLineEdit(groupBox_2);
  63.     byte15Edit->setObjectName(QString::fromUtf8("byte15Edit"));
  64.     byte15Edit->setGeometry(QRect(417, 70, 31, 20));
  65.     byte9Edit = new QLineEdit(groupBox_2);
  66.     byte9Edit->setObjectName(QString::fromUtf8("byte9Edit"));
  67.     byte9Edit->setGeometry(QRect(177, 70, 31, 20));
  68.     byte16Edit = new QLineEdit(groupBox_2);
  69.     byte16Edit->setObjectName(QString::fromUtf8("byte16Edit"));
  70.     byte16Edit->setGeometry(QRect(457, 70, 31, 20));
  71.     byte17Edit = new QLineEdit(groupBox_2);
  72.     byte17Edit->setObjectName(QString::fromUtf8("byte17Edit"));
To copy to clipboard, switch view to plain text mode 

I then declare an array of QLineEdit Pointers. And point at the 18 instances of QLineEdit.

Qt Code: 
  1. QLineEdit * LineEditArray[18];
  2.  
  3.        LineEditArray[0] =  ui.byte0Edit;
  4. 	LineEditArray[1] =  ui.byte1Edit;
  5. 	LineEditArray[2] =  ui.byte2Edit;
  6. 	LineEditArray[3] =  ui.Byte3Edit;
  7. 	LineEditArray[4] =  ui.byte4Edit;
  8. 	LineEditArray[5] =  ui.byte5Edit;
  9. 	LineEditArray[6] =  ui.byte6Edit;
  10. 	LineEditArray[7] =  ui.byte7Edit;
  11. 	LineEditArray[8] =  ui.byte8Edit;
  12. 	LineEditArray[9] =  ui.byte9Edit;
  13. 	LineEditArray[10] = ui.byte10Edit;
  14. 	LineEditArray[11] = ui.byte11Edit;
  15. 	LineEditArray[12] = ui.byte12Edit;
  16. 	LineEditArray[13] = ui.byte13Edit;
  17. 	LineEditArray[14] = ui.byte14Edit;
  18. 	LineEditArray[15] = ui.byte15Edit;
  19. 	LineEditArray[16] = ui.byte16Edit;
  20. 	LineEditArray[17] = ui.byte17Edit;
To copy to clipboard, switch view to plain text mode 

I then try to set the text of the QLineEdit. This is where the error is generated on the first call to setText.

Qt Code: 
  1. for(int i = 0; i < 18; i++)
  2. {
  3. 	LineEditArray[i]->setText("");
  4. }
To copy to clipboard, switch view to plain text mode 

I can tell I'm overlooking something. Any ideas? Thanks.
