c++ - 将 QKeySequence/QKeySequenceEdit 限制为只有一个快捷方式

Question

是否可以限制QKeySequence在QKeySequenceEdit中只显示一个快捷方式？目前它最多支持 4 个快捷方式。我的应用程序仅支持一个快捷方式的键序列，例如Ctrl+A 或 Ctrl+C 而不是例如Ctrl+A、D 或 Ctrl+C、X、Z。

是否可以将 QKeySequence 或 QKeySequenceEdit 限制为仅一个键序列？

解决了它，不是最好的解决方案，但很快......如果你想要更多自定义的东西，我认为你必须自己构建它......

customkeysequenceedit.h:

#ifndef CUSTOMKEYSEQUENCEEDIT_H
#define CUSTOMKEYSEQUENCEEDIT_H

#include <QKeySequenceEdit>

class QKeyEvent;

class CustomKeySequenceEdit : public QKeySequenceEdit
{
    Q_OBJECT

public:
    explicit CustomKeySequenceEdit(QWidget *parent = 0);
    ~CustomKeySequenceEdit();

protected:
    void keyPressEvent(QKeyEvent *pEvent);
};

#endif // CUSTOMKEYSEQUENCEEDIT_H

customkeysequenceedit.cpp:

#include "customkeysequenceedit.h"

#include <QKeyEvent>

CustomKeySequenceEdit::CustomKeySequenceEdit(QWidget *parent) : QKeySequenceEdit(parent) { }

CustomKeySequenceEdit::~CustomKeySequenceEdit() { }

void CustomKeySequenceEdit::keyPressEvent(QKeyEvent *pEvent)
{
    QKeySequenceEdit::keyPressEvent(pEvent);

    QKeySequence seq(QKeySequence::fromString(keySequence().toString().split(", ").first()));
    setKeySequence(seq);

}
