How to build widgets from any .ui files created by QtDesigner

[Amry]

Hi guys,

I would like to make something like GUI creator which takes an ui file and creates widgets in it, and show in a window.
So I have created a button on click I use QFileDialog to get a file.
And then I would like to use the ui file from QFileDialog to create that gui/widgets and show in a window.

I have tried QFormbuilder, but it always gives me compile error "undefined reference to `QFormBuilder::QFormBuilder()'"

Is there a way to do it in qt5?

Any help appreciated

Undefined reference sounds like just missing linker lib. Can you show any code (.pro settings)? You're probably missing something like Qt += widgets or whatever the module the QFormBuilder is in.

Hi Chris,

Here is my code.
@
void MainWindow::load()
{
QString fname = QFileDialog::getOpenFileName(this, tr("Load file ..."),QDir::currentPath(),tr("UI Files (*.ui)"));
ui->path->setText(fname);

QFormBuilder loader;
     QFile file("untitled.ui");
     file.open(QFile::ReadOnly);
     QWidget *myWidget = loader.load(&file, this);
     file.close();

     QVBoxLayout *layout = new QVBoxLayout;
     layout->addWidget(myWidget);
     setLayout(layout);


QMainWindow *mnw = new QMainWindow();
mnw->setCentralWidget(myWidget);
mnw->show();

}

I also wanted it to take the file that is loaded by QFileDialog, but it gives also error.

Any idea what is wrong?

Hi,

I have solved it by adding designer into my .pro file.

Thanks anyway.
