如何从 QMainWindow 中删除栏 [英] How to remove bar from QMainWindow

问题描述

我正在尝试删除此栏，但无法删除它(它位于工具栏下方):

I'm trying to delete this bar, butI can't get rid of it (it's locate just under the toolbar):

那个酒吧的名字是什么，我如何访问它?谢谢.

What is the name of that bar,how can I access it? Thank you.

推荐答案

如果你添加了那个工具栏，你可能有一个指向它的指针?如果是，您可以简单地调用:

If you added that tool bar you probably have a pointer to it? If yes, you can simply call:

removeToolBar(toolbar);

在您的 QMainWindow 类中.否则，您可以从主窗口中删除所有工具栏:

in your QMainWindow class. Otherwise you can remove all tool bars from the main window as:

QList<QToolBar *> allToolBars = mainWindow->findChildren<QToolBar *>();
foreach(QToolBar *tb, allToolBars) {
    // This does not delete the tool bar.
    mainWindow->removeToolBar(tb);
}
