Changing widget's name in both design view and code view in Qt

I'm just starting Qt5 using QtCreator, and I have a question regarding changing the name of widgets in design view.

So, for example, I have a QComboBox and I I use findChild() to find it (this is in mainwindow.cpp):

QComboBox *comboBoxType;
void MainWindow::on_Start_clicked()
{

    comboBoxType = ui->stackedWidget->findChild<QComboBox *>("typeComboBox", Qt::FindChildrenRecursively);
    comboBoxType->addItem("Hash");
    comboBoxType->addItem("Hash2");
}

But when I changed the name of the the widget from typeComboBox to typeBox in design view, for instance, the typeComboBox name in mainwindow.cpp wasn't changed, and led to an obvious crash:

02:32:37: The program has unexpectedly finished.
02:32:37: The process was ended forcefully.
02:32:37: D:\...\build-cryptog-Desktop_Qt_5_15_2_MinGW_64_bit-Debug\debug\cryptog.exe crashed.

Is there any ways of changing/updating both name, in .ui and mainwindow.cpp simultaneously, or is there a better way other than manually typing in the name in mainwindow.cpp, so that I don't have to go find the culprit in code after I change something in design view?

Solution

  • In QtCreator you can use the Advanced Find menu (Ctrl+Shift+F) to do a find and replace operation across all files in the project.

    Enable the options "Case sensitive" and "Whole words only" to limit the match to the exact name.
