how to add children to the QTree Widget

[ManiRon]

@mrjj said in how to add children to the QTree Widget:

UNAME = $$system(uname -s)
contains( UNAME, [lL]inux ):message( This looks like Linux ($$UNAME) to me )

So thsi is for linux?
UNAME = $$system(uname -s)
contains( UNAME, [lL]inux ):message( This looks like Linux ($$UNAME) to me )

If i want to check for xenomai what should i do sir?

[ManiRon]

@mrjj

Is there any way sir?

[mrjj]

@ManiRon
Hi
Yes you can do it.
But you need to find out how. I dont have xenomai
installed so i cant say how we can spot the difference between plain linux and
xenomai
so try
UNAME = $$system(uname -s)
on both systems and see what it types.
If different, you can use that as a flag

@mrjj

contains( UNAME, [lL]inux ):message( This looks like Linux ($$UNAME) to me )

This message where it will be printed sir?

[ManiRon]

@ManiRon

And i have another doubt ?

[mrjj]

@ManiRon
yes message print out the variable name $$UNAME ( what it contains)
what is other doubt?

[ManiRon]

@mrjj my anogther doubt is

I am trying to view the data in a list . i have specified already

[ManiRon]

@mrjj

And i have another doubt .
I am trying to see the data which i have inserted into my QList . I can see the size but i cannot see the data.

Code:

QList<QString> m_Data;
for(int i=1;i<3;i++)
{
Data = QString("SubItem"+QString::number(i));
m_Data.append(Data.toLatin1().constData());
QString H = m_Data.at(i); //trying to see data
qDebug()<<"Data"<< m_Data.at(i);
}

while running the application crashesdonno why

[mrjj]

@ManiRon
Hi
what you mean u can see the size but not the data?

qDebug()<<"Data"<< m_Data.at(i); <<< u print index from 1,2,3
but u call append so first call, there is data in zero
but u print 1
then next loop
you print from 2, but only data in 0,1
and so on.
it starts in zero. so adjust the for loop.

for(int i=0;i<2;i++)
{
Data = QString("SubItem"+QString::number(i+1));
m_Data.append(Data.toLatin1().constData());
qDebug()<<"Data"<< m_Data.at(i);  //trying to see data
}

@mrjj said in how to add children to the QTree Widget:

but

if i give

int i = m_data.size();
and print the i value , I can see the data size that which i have inserted in the list.

But if i try to see the data

QString H = m_data.at(i);
and print the H value using qDebug i data is not coming and the application crashes

[mrjj]

@ManiRon
Yes, you access to high index.
as u start with 1.
and list start with zero.
So that can crash.
