Remove widget from a layout
How do I remove a widget from a layout?
Code:
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
startGui = new StartScreenGUI();
ui->verticalLayout->insertWidget(0,startGui);
}
void MainWindow::switchToStart()
{
deleteGuis();
startGui = new StartScreenGUI();
ui->verticalLayout->insertWidget(0,startGui);
}
void MainWindow::deleteGuis()
{
ui->verticalLayout->removeWidget(startGui);
ui->verticalLayout->removeWidget(schemeGui);
ui->verticalLayout->removeWidget(settingsGui);
ui->verticalLayout->removeWidget(listGui);
ui->verticalLayout->removeWidget(historyGui);
}
What have I done wrong here? What happens is that it just put the new widget on top on the old one. I have tried the update() function but it does not seem to do anything in this case. It works if I delete the widget but as I do not know what widget that is in the layout at the moment I have no idea how to destroy the widget as I can not delete widgets that is already deleted(program freezes) |
