class Ui MainWindow has no member named actionnew ui actionnew ssetIcon的錯誤解決方案

C:\Users\Administrator\Desktop\untitled\mainwindow.cpp👎 In
constructor ‘MainWindow::MainWindow(QWidget*)’:

C:\Users\Administrator\Desktop\untitled\mainwindow.cpp:12: error:
‘class Ui::MainWindow’ has no member named ‘actionnew’
ui->actionnew->setIcon(QIcon(":/Image/Frame.jpg"));
^

當看見這種錯誤，你應該看看你的UI的界面的按鈕，雙擊進入

	//與UI中的標識一一對應
    ui->actionnew_2->setIcon(QIcon(":/Image/Frame.jpg"));
    ui->actionne->setIcon(QIcon(":/Image/up.png"));
