Closing widget

tactical77

Hi,

I'm having some problems with a connect command. I've been using the qtdesigner so far and everything worked. Now I need to code it manually. The problem is the mainwindow close but I need to close the child widget. Here's the code.

void MainWindow::on_actionKundensuche_triggered()
{

QWidget *window = new QWidget;


QPushButton *button1 = new QPushButton("OK");
QPushButton *button2 = new QPushButton("Abbrechen");

QLineEdit *line1 = new QLineEdit();

window->setFixedSize(300, 250);


QVBoxLayout *layout1 = new QVBoxLayout;
layout1->addWidget(line1);

QHBoxLayout *layout2 = new QHBoxLayout;
layout2->addWidget(button1);
layout2->addWidget(button2);
layout1->addLayout(layout2);

window->setLayout(layout1);

window->show();


connect(button2, SIGNAL(clicked()), this, SLOT(on_abbrechen_triggered()));

  }


void MainWindow::on_abbrechen_triggered()
{
    close();
}

@tactical77 said in Closing widget:

connect(button2, SIGNAL(clicked()), this, SLOT(on_abbrechen_triggered()));

After this do something like this:

connect(button2, SIGNAL(clicked()), window, SLOT(deleteLater()));

If you want to close the widget why do you call close() on your MainWindow?
Call close on your widget instead:

void MainWindow::on_abbrechen_triggered()
{
    window->close();
}
