Question

如上所述，我的任务是更改使用QT 5.7的现有Visual Studio项目的代码。在我之前从事此工作的学生不幸地用我完全不熟悉的cmake构建了他的项目，但不幸的是，我绝对没有时间参与其中。

我的第一个尝试是建立一个新的VS项目，将所有必要的源文件和QT文件粘贴到其中。这导致了几个问题，其中之一是我必须在所有Q类中删除，保存和重写<!DOCTYPE html> <html> <head> <title>HOME</title> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <link rel="stylesheet" type="text/css" href="../css/home.css"> </head> <body class=background> <div class="btn-container"> <button class="button login">LOGIN</button> </div> <div class="btn-container"> <button class="button register">REGISTER</button> </div> </body> </html>。

这告诉我，实际的工作流程从一开始就在破坏项目。

关于这一点，我的前任使用Q_OBJECT连接Gui对象（如Buttons）的信号和插槽。调试时得到

QMetaObject::connectSlotsByName

对于GUI中所有现有的QWidget-Childs。

这似乎很奇怪，因为此类按钮等的信号必须以moc代码存在（当然存在相应的插槽），对吗？

项目中存在大量的Gui元素，因此我宁愿不要对每个元素都使用connect。

问题：

1。）是否有建议的工作流程，该工作流程使人脚射门的频率降低？ 2.）为了使Qt的元对象编译器能够创建QMetaObject::connectSlotsByName: No matching signal for on_[some Gui Obejct]_clicked()和ui_*.h，需要moc_*.cpp，*.ui和潜力资源文件，对吗？ 3.）该项目最初由cmake构建的事实在多大程度上会影响Qt-meta编译？

非常感谢您

编辑： QMainWindow-Class *.qrc的其他信息和代码示例。我添加了Navigation_Gui行，这会产生过多的违规行为，我认为不应该这样做。

connect

标题

Navigation_Gui::Navigation_Gui(QWidget *parent)
: QWidget(parent){

this->Storage = new ThreadStorage();                            
this->CamPtr = new CamBar(this->Storage);   
this->NavPtr = new Navigation(this->CamPtr, this->Storage);

ui.setupUi(this);

this->getRegPoints = false;
this->Storage->Log << "Main Gui initialized" << endl;

connect(this->ui.pushButton, SIGNAL(clicked()), this, SLOT(on_pushButton_clicked())); }

这是生成的Ui头

时

connect

我明白了

connect(this->ui.pushButton, SIGNAL(clicked()), this, SLOT(on_pushButton_clicked()));

这也很奇怪。
