一些Qt错误 - 如何解决？

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(); 
} 

而且，试图运行该程序时，遇到下列错误：如下

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 

的ui_checkabder.h内容是：

关于如何解决这些问题的任何想法？

Answer 1

您的分类名称是Ui_Form和Ui::Form而不是CheckAbder。你应该在Designer中重命名它。

Answer 2

你需要了解一点点。文件名与生成的Ui命名空间内容无关。 .ui文件中的小部件名为“Form”而非CheckAbder。使用UI ::形式在您的.cpp文件

重命名表

1. 开始到CheckAbder在你的.ui文件

还要确保，您：您可以通过两种方式解决你的问题。更改后的UI文件添加到项目中，所以它将会被自动生成新的用户界面_ * .h文件的.ui

Answer 3

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

应该

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