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.

I want to disable the "Advanced" tab whenever the Boolean result is false. I thought it would be as simple as this code:

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

Unfortunately, this code does not disable the tab, it remains enabled even when I check it:

tabWidget->tabBar()->isTabEnabled(1);  // This returns true

Why doesn't the tab become disabled? Is there another way to do it?

I am using Qt 5.4.0.

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);
}

QTabWidget - prevent change of tab without disabling tabs, The checkbox permits to enable or disable a tab when its value is changed if all the pages are disabled, QTabWidget will show one of them. Here is my take on this. I've created a class that inherits QTabWidget. What I do is; set the "maximum vertical size of QTabWidget" to its tabBars height to hide the panels. It is a hacky solution and I had to add some extra lines to deal with quirks. file: hidabletabwidget.h

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 ) ;
}
