Splitter doubt, want a minimal space for the left widget.

I have 2 frames arranged by a splitter.
I'd want 200 px min for frame1 (the left).
Sincerely I dont know what policy to apply ( nothing works)
Any help would be appreciated

Set the QWidget::sizePolicy() of the left widget to QSizePolicy::MinimumExpanding for horizontal, and its minimum width to 200 QWidget::setMinimumWidth()

Code:

---

class MainWindow: public QMainWindow {
    Q_OBJECT
public:
    MainWindow(QWidget *p = 0): QMainWindow(p) {
        QSplitter *splitter = new QSplitter(this);
        QTextEdit *left = new QTextEdit(this);
        left->setSizePolicy(QSizePolicy::MinimumExpanding, QSizePolicy::Preferred);
        left->setMinimumWidth(200);
        QTextEdit *right = new QTextEdit(this);
        splitter->addWidget(left);
        splitter->addWidget(right);
 
        setCentralWidget(splitter);
    }
public slots:
private:
};
