Window freez on type text into TFileEditor

[paule32]

Hello, I oversee something, the Code compiled fine, but on runtime, the Application can not be close (Alt+X), and the Window can not be closed. Please Help. I have the following Code:

void TVDemo::tvEditor()
{
    TMyTvEditor *editor = (TMyTvEditor *) validView(new TMyTvEditor(TRect(0, 0, 79, 23)));

    if (editor != 0) {
        editor->helpCtx = hcCalendar;
        deskTop->insert( editor );
    }
}

class TMyTvEditor : public TWindow {
public:
    TMyTvEditor(const TRect& bounds):
        TWindowInit(&TMyTvEditor::initFrame),
        TWindow(bounds, "Mein Fenster", wnNoNumber) {

        // Viewer erstellen
        viewer = new TScroller(TRect(2, 2, 39, 23),
            standardScrollBar(sbHorizontal),
            standardScrollBar(sbVertical));
        insert(viewer);

        // Text-Editor erstellen
        TScrollBar *hScrollBar = new TScrollBar( TRect( 2, size.y - 1, size.x - 24, size.y ) );
        hScrollBar->hide();
        insert(hScrollBar);

        TScrollBar *vScrollBar = new TScrollBar( TRect( size.x - 23, 1, size.x - 22, size.y - 1 ) );
        vScrollBar->hide();
        insert(vScrollBar);

        editor = new TFileEditor(TRect(1, 1, size.x - 24, size.y - 1), hScrollBar, vScrollBar, nullptr, "www.txt");
        insert(editor);

        options |= ofSelectable;
    }

    void handleEvent(TEvent &event) {
        TWindow::handleEvent(event);
        if (event.what == evCommand) {
            switch (event.message.command) {
                case cmClose:
                    close();
                    clearEvent(event);
                    break;
                case cmButton1:
                    // Aktion für Schaltfläche 1
                    break;
                case cmButton2:
                    // Aktion für Schaltfläche 2
                    break;
            }
        }
        else {
            clearEvent(event);
        }
    }

private:
    TScroller *viewer;
    TFileEditor *editor;
    TButton *button1;
    TButton *button2;
};
