问题描述

我希望QAction由多个键盘快捷键触发.根据文档，应该通过将QKeySequences列表传递给 QAction来实现:: setShortcuts()，但实际上似乎只使用列表中的第一个键序列.

I want a QAction to be triggered by multiple keyboard shortcuts. According to the documentation, this should be possible by passing a list of QKeySequences to QAction::setShortcuts() , but in practice it seems that only the first key sequence in the list is used.

我创建了一个简短的示例来演示该问题.在这里，我试图同时包含 + 和 + (这是 + 和Mac上的 + )触发我的操作".以这种形式，只有 + 会触发操作.如果交换了两个快捷方式，以便首先使用 + ，则它将触发操作，并触发 + 不会.最后，如果所有快捷方式列表中的内容都被注释掉，并且QKeySequence :: Cut所在的行未注释，则即使文档说，它既映射到 + K 和 + .代码:

I've created a short example that demonstrates the problem. Here I'm trying to have both + and + (which are + and + on the Mac) trigger "My Action". In this form, only + will trigger the action. If the two shortcuts are swapped so that + is first, then it will trigger the action and + will not. Finally, if all of the shortcut list stuff is commented out and the line with QKeySequence::Cut is uncommented, only + will work even though the documentation says that it maps to both + and + on the Mac. The code:

#include "mainwindow.h"
#include <QMenuBar>
#include <QAction>

MainWindow::MainWindow() {
    QMenu* menu = new QMenu("Menu");
    menuBar()->addMenu(menu);
    QAction* action = new QAction("My Action", this);
    // Create a list with two shortcuts
    QList<QKeySequence> shortcuts;
    shortcuts.append(QKeySequence(Qt::META + Qt::Key_K));
    shortcuts.append(QKeySequence(Qt::CTRL + Qt::Key_X));
    action->setShortcuts(shortcuts);
    // Alternatively, use one of the QKeySequence::StandardKey enums
    //action->setShortcuts(QKeySequence::Cut);
    connect(action, SIGNAL(triggered()), this, SLOT(doIt()));
    menu->addAction(action);
}

// slot
void MainWindow::doIt() { qDebug("MainWindow::doIt()"); }

如果有关系，我正在使用Mac OS X 10.9.2，并且已经在Qt 5.2.1和Qt 5.3.0中进行了尝试.

If it matters, I'm using Mac OS X 10.9.2, and I've tried this with Qt 5.2.1 and Qt 5.3.0.

我包含了头文件和main.cpp，以防任何人只想复制并粘贴来运行示例，但是其中没有有趣或不标准的地方.头文件:

I'm including the header file and main.cpp in case anyone wants to just copy-and-paste to run the example, but there is nothing interesting or non-standard in them. Header file:

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    MainWindow();

public slots:
    void doIt();
};

#endif // MAINWINDOW_H

main.cpp:

#include "mainwindow.h"
#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();

    return a.exec();
}
