Unable to access members of same class, giving seg fault

[stampede]

No return statements in functions returning non-void:

QWidget* ApplicationLog::createLogWindow()
{
  m_pCmdLogHL = new QHBoxLayout(this);
  m_pLogTE =    new QTextEdit(this);
  m_pCmdLogHL->addWidget(m_pLogTE);
 // return !
}
 
QWidget* ApplicationLog::createFrameWindow()
{
    m_pButtonsHL = new QHBoxLayout(this);
    m_pMinMaxBut = new Button(this,"Minimize");
     connect(m_pMinMaxBut,SIGNAL(clicked()),this,SLOT(logWindowMinMax()));
m_bIsMaximize = 1;
// return !
}

QWidget* ApplicationLog::createLogWindow()
{
  m_pCmdLogHL = new QHBoxLayout(this);
  m_pLogTE =    new QTextEdit(this);
  m_pCmdLogHL->addWidget(m_pLogTE);
 // return !
}

QWidget* ApplicationLog::createFrameWindow()
{
    m_pButtonsHL = new QHBoxLayout(this);
    m_pMinMaxBut = new Button(this,"Minimize");
     connect(m_pMinMaxBut,SIGNAL(clicked()),this,SLOT(logWindowMinMax()));
m_bIsMaximize = 1;
// return !
}

Another thing, check if createLogWindow() is called before trying to access m_pLogTE object.

The OP's code won't even compile, much less execute, so obviously we are not seeing the whole story. As amleto says in every post:

If you have a problem, CUT and PASTE your code. Do not retype or simplify it. Give a COMPLETE and COMPILABLE example of your problem. Otherwise we are all guessing the problem from a fabrication where relevant details are often missing.
