如何禁用QTabWidget中的一个选项卡? [英] How do I disable one tab in a QTabWidget?

问题描述

我有一个名为tabWidget的QTabWidget.它具有三个选项卡:基本"，高级"和当前结构".这些选项卡按此顺序显示在窗口小部件中.

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.

每当布尔值result为false时，我都想禁用高级"选项卡.我认为这将像下面的代码一样简单:

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);
}

不幸的是，此代码不会禁用该选项卡，即使我选中它也会保持启用状态:

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

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

为什么该选项卡没有被禁用?还有另一种方法吗?

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

我正在使用Qt 5.4.0.

推荐答案

您可以使用成员函数根据您的代码段，它看起来像这样:

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

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