Question

我有以下main.cpp文件：

#include <QApplication>
#include "ui_checkabder.h"
#include <QDialog>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
Ui::CheckAbder ui;
QDialog *dialog = new QDialog;
ui.setupUi(dialog);
dialog->show();
return app.exec();
}

并且，在尝试运行程序时出现以下错误：

C:/Users/avbder/Desktop/abder/main.cpp:7: error: 'CheckAbder' is not a member of 'Ui'

C:/Users/avbder/Desktop/abder/main.cpp:7: error: expected ';' before 'ui'

C:/Users/avbder/Desktop/abder/main.cpp:7: error: expected ';' before 'ui'

C:/Users/avbder/Desktop/abder/main.cpp:9: error: 'ui' was not declared in this scope

ui_checkabder.h的内容如下：

关于如何解决这些问题的任何想法？

感谢。

Answer 1

您的班级名称是Ui_Form和Ui::Form，而不是CheckAbder。您应该在Designer中重命名它。

Answer 2

你需要了解一点点。文件名与生成的Ui名称空间内容无关。 .ui文件中的小部件名为“Form”而不是CheckAbder。您可以通过两种方式解决问题：

在.cpp文件中开始使用Ui :: Form
在.ui文件中将表单重命名为CheckAbder

另外请确保您的.ui文件已添加到项目中，因此更改后会自动生成新的ui _ * .h文件.ui

Answer 3

namespace Ui {
    class Form: public Ui_Form {};
} // namespace Ui

应该是

namespace Ui {
    class CheckAbder: public Ui_Form {};
} // namespace Ui
