我用确定/取消按钮创建了一个名为“new_dialog”的模式对话框。现在我想在“确定”按钮的插槽上工作。我右键单击按钮窗格,从上下文菜单中选择“转到插槽”命令;并得到一个错误:
在 mainwindow.cpp 中找不到带有 Ui::new_dialog 的类。检查包含指令(这是英文翻译)
如何为按钮分配插槽?
谢谢!
一些代码:
mainwindow.cpp 中有 new.ui 和 ui_new.h 指令:
#include "ui_new.h"
该对话框从主窗口调用:
void MainWindow::on_pushButton_clicked()
{
QDialog *new_dialog = new QDialog(0,0);
Ui_New newUi;
newUi.setupUi(new_dialog);
new_dialog->exec();
}
ui_new.h:
