Qt Problem

[NewFolder]

Hello guys,

I want to know how to run shell commands within Qt. This is my first application:

I want to find a File using file name and file location. But how can I do that? I try to do this:

void Dialog::on_lineEdit_textEdited(QString )
{
 
}
 
void Dialog::on_lineEdit_2_textEdited(QString )
{
 
}
 
void Dialog::on_pushButton_clicked()
{
    QString strText = QString("find ./%1 -name \'%2\' | zenity --text-info --title \'Find Files\'").arg(lineEdit.text()).arg(lineEdit_2.text());
}

void Dialog::on_lineEdit_textEdited(QString )
{

}

void Dialog::on_lineEdit_2_textEdited(QString )
{

}

void Dialog::on_pushButton_clicked()
{
    QString strText = QString("find ./%1 -name \'%2\' | zenity --text-info --title \'Find Files\'").arg(lineEdit.text()).arg(lineEdit_2.text());
}

To copy to clipboard, switch view to plain text mode 

But it doesn't work:

/home/tonto/Desktop/FindFiles/dialog.cpp:22: error: ‘lineEdit’ was not declared in this scope
/home/tonto/Desktop/FindFiles/dialog.cpp:22: error: ‘lineEdit_2’ was not declared in this scope

/home/tonto/Desktop/FindFiles/dialog.cpp:22: error: ‘lineEdit’ was not declared in this scope
/home/tonto/Desktop/FindFiles/dialog.cpp:22: error: ‘lineEdit_2’ was not declared in this scope

To copy to clipboard, switch view to plain text mode 

So, can anyone help me? Thanks.

PS: I use Ubuntu Linux.

As far as your lineedit error goes, is lineEdit a member variable of Dialog class ? May be you have some ui member variable and you need to do something like ui->lineEdit.

@aamer4yu
No, lineEdit is not a member variable of Dialog class. Please help me, I don't know what to do!

[aamer4yu]

what is the lineEdit member of then ? You need to properly access it through its holder / creator

I'm not sure, but I think lineEdit is a member of Dialog class.
So, what can I do?

Is it a school assignment of some kind?
