结合Qt中的工具栏和标题栏 [英] Combine toolbar and title bar in Qt

问题描述

如何在顶部栏中实现工具栏，例如Tiled完成了吗?

How can the toolbar be implemented in the top bar, like, for example, Tiled has it done?

通常，工具栏如下所示:

Normally, the toolbar looks like the follows:

示例代码的当前状态:

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    explicit MainWindow(QWidget *parent = nullptr) {
        auto *tbar = new QToolBar();  
        tbar->addWidget(new QPushButton("Push Me"));
        this->addToolBar(tbar);
    }
};

推荐答案

如果仍在使用Qt 4.x，则可以使用QMainWindow中包含的setUnifiedTitleAndToolBarOnMac(bool set)函数:

If you are still using Qt 4.x, you can just use the setUnifiedTitleAndToolBarOnMac(bool set) function that is included in QMainWindow:

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    explicit MainWindow(QWidget *parent = nullptr) {
        auto *tbar = new QToolBar();  
        tbar->addWidget(new QPushButton("Push Me"));
        this->addToolBar(tbar);
        this->setUnifiedTitleAndToolBarOnMac(true); // activate Mac-style toolbar
    }
};
