How do I disable one tab in a QTabWidget?

Question

I have a QTabWidget called tabWidget. It has three tabs: \"Basic\", \"Advanced\", and \"Current Structure\". The tabs are displayed in the widget in that order

Answer 1

You can't, not this way.

You have to iterate through all the children in the Page and disable them.

Something like this:

QList<QWidget*> list = parentWidget->findChildren<QWidget*>() ;
foreach( QWidget* w, list ) {
   w->setEnabled( false ) ;
}

Answer 2

You can enable/disable individual tabs in a QTabWidget using the member function setTabEnabled(int index, bool enable).

Based on your code snippet, it would look like this:

bool result = false;
if (result == false)
{
  tabWidget->setTabEnabled(1, false);
}

Answer 3

You could disable the layout of the tab.

bool result = false;
if (result == false)
{
  tabWidget->widget(1)->layout()->setDisabled(true);
}

Answer 4

If you use Qt Widgets Application template and Advanced tab's name is tabAdvanced (you can check the name in Object Inspector), this should work:

ui->tabAdvanced->setEnabled(false);
