Show/Hide sub-tab on QTabWidget

问题

Assuming I have a QTabWidget that contains 5 sub-tabs. Now I want to show/hide a sub-tab in one of 5 sub-tabs by following code

ui->twListTabs->widget(0)->hide();           // Hide first sub-tab

But this didn’t work for me. Do you have any solutions?

Thanks!

You only have the option to use:

void QTabWidget::removeTab(int index)

You need to store the pointer to the QWidget in the tab so that you can later insert it.

You could e.g. do something like:

class TabWidget : public QTabWidget
{
   Q_OBJECT

      enum tabwidgets {tabwidget1,tabwidget2,...,number_of_tabwidgets};
      QWidget* widgets_[number_of_tabwidgets];
   public:
      TabWidget(QWidget* parent=0)
      : QWidget(parent)
      {
         for(int i(0);i<number_of_tabwidgets;++i)
     {
        switch(i)
        {
           case tabwidget1:
              insertTab(i,widgets_[i]=new TabWidget1,QString::number(i));
           ....
        }
     }
      }
};
