How to build widgets from any .ui files created by QtDesigner
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.
Here is my code.
QString fname = QFileDialog::getOpenFileName(this, tr("Load file ..."),QDir::currentPath(),tr("UI Files (*.ui)"));
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?
I have solved it by adding designer into my .pro file.
