Member access problem, from same class,
-
I am trying to create a slot from object to other
frame to log , but both belongs to same classwhen trying to access objects placed on log , they are becoming invalid.
how to solve the problem?
@QWidget* ApplicationLog::createLogWindow()
{
m_pCmdLogHL = new QHBoxLayout(this);
m_pLogTE = new QTextEdit(this);
m_pCmdLogHL->addWidget(m_pLogTE);
}@@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;
}@@void ApplicationLog::logWindowMinMax()
{
qDebug()<<"slot invoked" ;
if(m_bIsMaximize)
{
m_pLogTE->setVisible(false);
m_pMinMaxBut->setTooltip("Maximize");
m_bIsMaximize = 0;
}
else
{
m_pLogTE->setVisible(true);
m_bIsMaximize = 1;
m_pMinMaxBut->setTooltip("Minimize");
}
}@in the main window i am calling
@ QWidget* frame = framewindow->createFrameWindow();
QWidget* log = logwindow->createLogWindow();@this particular line is giving problem (segmentation)
@ m_pLogTE->setVisible(false);@why is it wrong to access that object,how to access the object?

when you do it this way you must ensure that you call the methods in the right order to ensure that all dependent methods are accessing initialized members.
But i believe you've stripped out some code right? Thus it's hard to spot the error. The code more or less looks good, despite you're not setting the layout and not returning a widget in your methods while they are declared so, etc.
