Hi,
It was almost impossible, but it does not load the UI file:
GuiParser::GuiParser(QTreeWidget *tree)
{
treeWidget = tree;
QUiLoader uiLoader;
QFile file("mainwindow.ui"); // I also copied file to C: root
and wrote fix path here
// I also wrote here a file.open, but it does not help to change
it from unknown error to a better one
QMessageBox msgBox0;
msgBox0.setText( file.errorString() ); // gives UNKNOWN ERROR
msgBox0.exec();
ui = uiLoader.load(&file);
QMessageBox msgBox;
msgBox.setText( uiLoader.errorString() ); // An error occured
when reading the UI file at line 1, column 0. Premature end of
document.
msgBox.exec();
currentButton = NULL;
currentLabel = NULL;
}
