[Solved]add widget at runtime

[toho71]

Hello
I'm trying the example of Nokia where I try to loop out a groupboxes with lineedits at runtime
When I have done my loop it's only on groupbox visible.

@void ParseXMLExample::addPersonsToUI(QList< QMap<QString,QString> >& persons) {

while(!persons.isEmpty()) {
            QGroupBox* personGB = new QGroupBox("Person",this);
            QFormLayout* layout = new QFormLayout;
            QMap<QString,QString> person = persons.takeFirst();
            layout->addRow("First name", new QLineEdit(person["firstname"]));
            layout->addRow("Surname", new QLineEdit(person["surname"]));
            layout->addRow("E-mail", new QLineEdit(person["email"]));
            layout->addRow("Website", new QLineEdit(person["website"]));
            personGB->setLayout(layout);

            //this->_layout->addWidget(personGB); //This causes error
            personGB->show();


    }

}@

whats wrong I know that it is 3 posts in the list

So... who manages the position of the groupbox personGB? You are currently stacking them one on top of the other, it seems to me.

It was this code who was manage the position and the _layout is a Qpointer but it causes an error

@this->_layout->addWidget(personGB);@ //This causes error

I dont know how to complete this code so it works again.

"An" error is not very specific. What error does it cause?

You have to make sure that the base layout/widget where you want to put this widget on,
is setup well...

in this line:

@QGroupBox* personGB = new QGroupBox("Person",this);@

you are already parenting your QGroupBox to the underlaying widget..

try this:

mainwindow.cpp

@
#include "mainwindow.h"
#include "ui_mainwindow.h"

#include <QGroupBox>
#include <QFormLayout>
#include <QLineEdit>

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::CQMainWindow)
{
ui->setupUi(this);

vbox = new QVBoxLayout(); // var declared in headerfile as "QVBoxLayout *vbox;"
centralWidget()->setLayout(vbox); // set the base layout on the central widget

// Test Data
QMap<QString,QString> people;
people.insert("firstname", "Steven");
people.insert("surname", "Ceuppens");

QMap<QString,QString> people2;
people2.insert("firstname", "Jan");
people2.insert("surname", "Janssens");

QList< QMap<QString,QString> > data;
data << people << people2;

addPersonsToUI(data);

}

MainWindow::~MainWindow()
{
delete ui;
}

void MainWindow::addPersonsToUI(QList< QMap<QString,QString> >& persons) {

while(!persons.isEmpty()) {
    QGroupBox *personGB = new QGroupBox("Person", this);
    QFormLayout *layout = new QFormLayout;
    QMap<QString,QString> person = persons.takeFirst();
    layout->addRow("First name", new QLineEdit(person["firstname"]));
    layout->addRow("Surname", new QLineEdit(person["surname"]));
    layout->addRow("E-mail", new QLineEdit(person["email"]));
    layout->addRow("Website", new QLineEdit(person["website"]));
    personGB->setLayout(layout);

    vbox->addWidget(personGB);
}

}
