I may be wrong but you can use signal and slot (on changing textbox's text example):
//mainwindow.cpp constructor:
MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow)
{
// connection for accessing to UI from another UI
ProfileSearch* profilesearch = new ProfileSearch;
connect( profilesearch, SIGNAL(updateUI1Signal(const QString)), this, SLOT(updateUI2TextSlot(const QString) ) );
// launch profilesearch form:
profilesearch.exec();
}
//mainwindow.h
{
public slots:
void updateUI2TextSlot( const QString text ) {ui->MWtextEdit->setText(text);} // set new text in mainwindow form
}
//profilesearch.h
signals:
void updateUI1Signal(const QString text);
// row click event handler
void ProfileSearch::on_row_column_whatewer_clicked()
{
emit updateUI1Signal("Hello from ProfileSearch form to MainWindow form");
}
