在Qt中聲明QVector類類型時出錯。聲明類類型QVector時出錯
錯誤:「不完全類型是不允許的」
我不明白是什麼原因導致這個錯誤。
如果我#include「storage.h」在main.cpp中並聲明Qvector的類存儲它工作正常,但是當我在波形類中做同樣的事情時,它報告錯誤。
我試過向前聲明波形類中的存儲類,但仍然得到相同的錯誤。
任何幫助?
的main.cpp
#include "test_subject_02.h"
#include <QtGui/QApplication>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
TEST_SUBJECT_02 w;
w.show();
return a.exec();
}
test_subject_02.h
#ifndef TEST_SUBJECT_02_H
#define TEST_SUBJECT_02_H
#include <QtGui/QMainWindow>
#include "ui_test_subject_02.h"
#include"waveform.h"
#include "storage.h"
class TEST_SUBJECT_02 : public QMainWindow
{

public:
TEST_SUBJECT_02(QWidget *parent = 0, Qt::WFlags flags = 0);
waveform *wv;

QVector<storage> ser; //works fine here
wv->readfile("e:/testing2/result/3/abc.cur");
}

waveform.h

}
waveform::~waveform()

storage.h定義
#ifndef STORAGE_H
#define STORAGE_H
#include <QObject>
class storage : public QObject
{
Q_OBJECT
public:

哦..那個愚蠢的錯誤。謝謝 – secretgenes
