QTabWidget上的“显示/隐藏"子选项卡

问题描述：

假设我有一个包含5个子选项卡的QTabWidget.现在，我想通过以下代码在5个子标签之一中显示/隐藏一个子标签

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

但这对我不起作用.有什么解决办法吗?

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

谢谢！

答

您只能选择使用:

void QTabWidget::removeTab(int index)

您需要将指向QWidget的指针存储在选项卡中，以便以后可以将其插入.

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

您可以例如做类似的事情:

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));
                ....
            }
        }
    }
};
