  Hallo, ich möchte unter Windows 7,8,10,… mit VC 2017 programmieren. Welche Klassenbibliothek sollte ich benutzen? Ich habe schon (bis 2005) mit VC 6, MFC programmiert und hatte gute Erfahrung damit. Jetzt geht es um ein neues Projekt: 1. Hardware Programmierung, 2. Datenbank, 3. Internet-Verbindung, … Meine erste Wahl wäre “VC 2017 mit MFC“. Nach meiner Recherche im Internet die Entwicklung von MFC ist gestoppt. Ist Desktop-Anwendung-Entwicklung mit WPF (Windows Presentation Foundation) eine gute Wahl? Wenn es um Web geht, dann benutze ich: PHP, JavaScript, jQuery, HTML, Linux server debian/ ubuntu, Postfix Mailserver (Dovecot, Ubuntu), Webserver Apache. Bei MFC kann man CHtmlView, CDHtmlDialog, … verwenden, um z.B. leichter HTML und JS für die Oberfläche zu benutzen. Kann man auch mit WPF für die Oberfläche von Desktop-Anwendungen auch HTML und JS verwenden? Wie wäre es die Wahl von Sciter (oder QT)? Laut https://sciter.com/: “… Sciter allows using time proven, robust, and flexible HTML and CSS for GUI definition, and GPU accelerated rendering.” Wäre es eine schlechte Entscheidung, wenn man VC 2017 mit Sciter kombinieren würde? (PS: Ja, ich habe die Beiträge im Forum gelesen, trotzdem möchte ich speziell in meinem Fall eure Meinung darüber hören) Vielen Dank im Voraus, Sandro.

  Vielen Dank! Mit dem Textstream geht es: //Button um Textdatei zu erstellen void MainWindow::on_pushButton_clicked() { filename = QFileDialog::getSaveFileName(this,"Datei speichern...", QDir::currentPath(), "Texte (*.txt)"); } //Button um in Textdatei zu schreiben void MainWindow::on_pushButton_2_clicked() { QFile file(filename); file.open(QIODevice::WriteOnly); QTextStream stream(&file); //#include <QTextStream> stream << ui->lineEdit->text(); } Alles geht jetzt ohne Fehler.

  Ich werde erstmal ohne weitermachen. Es wird mir nicht schaden sich erstmal überhaupt richtig mit Qt zu befassen. Kleine Apps bauen kann ich auf jeden Fall damit wobei eigentlich Desktopanwendungen bei mir im Vordergrund stehen. Und wenn ich mich dann damit sicher und vertraut fühle kann ich mir nochmal Felgo anschauen. Dann kann ich auch besser einschätzen, ob es mir wirklich Vorteile bringt oder nicht.

  Damit kann man z.B. die eigentlichen Daten verwalten. Sagen wir, du hast eine Klasse "Auto", und eine Tabelle, die irgendwelche Daten zu den Autos anzeigt. Dann steckt hinter der DisplayRole z.B. der Markenname. Aber du hast auch irgendwelche Operationen, bei denen du das Auto selbst brauchst. z.B. ein Knopf, und wenn man auf den drückt, wird ein Video zu dem markierten Auto abgespielt. Dazu brauchst du irgendwelche Daten, die nicht sichtbar sind.

  Du solltest dir immer was denken, wenn du irgendwas auf dem Heap erzeugst Das ist eine gute Grundeinstellung in C++.

  Ja, da schau ich natürlich schon nach. Aber vielleicht gibts noch andere Quellen, die gut/strukturiert die wichtigen Konzepte beschreiben? Diese Beispiele habe ich schon gesehen. Mag sein, dass ich blind bin, aber ich erkenne da nichts neues, ich vermute, das würde sich genauso wie bei mir verhalten. Bzw., es kann gut sein, dass ich beim Aufbau des Layouts was falsch gemacht habe. Evtl. ist die MouseArea zu groß und geht über die ListView hinaus. Ich kann nämlich die Items beliebig im Fenster positionieren, obwohl die ListView 100 Pixel breit sein sollte. Woran liegt das?

  Das wirst du dann selber programmieren müssen (außer du findest ein Custom Control dafür im Netz), s. z.B. Qt: How to add two widgets (say QPushButton) to the status bar, one to the left and other to the right side?

  Speichermanagement von Zeigern in QT5

  @Burkhi sagte in Speichermanagement von Zeigern in QT5: Mir ist nicht klar, ob bei Qt bei der Übergabe des Parent dieser später den Speicher der untergeordneten Objekte wieder freigibt Ja. @Burkhi sagte in Speichermanagement von Zeigern in QT5: Nach meiner Erfahrung bieten sich bei Speicherallokationen in C++ std::unique_ptr bzw. std::shared_ptr am besten an, seitdem ich diese verwende, habe ich keinerlei Probleme mehr mit Speicherlecks. Ganz so einfach ist das nicht... Denk mal an eine Software in der Größenordnung 5-10 Mio Zeilen Code, über Jahrzehnte gewachsen, auch noch mit dutzenden 3rdparty Komponenten, die teilweise ganz unterschiedliche Speicherverwaltungsstrategien verfolgen. Dann teilweise auch noch sehr viele Querreferenzen (über viele Ecken), Caches usw. Und dann lässt du das auf einem Live Server paar Tage laufen, und hast das Gefühl, das verbraucht vielleicht etwas zu viel Speicher ^^ Klar, in den letzten Jahren sind Memleaks viel seltener geworden, grad auch wegen den Smartpointern. Aber wenn wir doch mal irgendwo einen vermuten, ist es teilweise immer noch extrem aufwändig, den zu finden.

  Ja, das hat so jetzt funktioniert. Dann versteh ich allerdings nicht, warum das nicht schon beim ersten mal geklappt hatte. Aber gut, das reicht mir erstmal, will das nicht mehr untersuchen.

  Ich mache es genau so wie @DocShoe es selber geschrieben hat. Nur das "adjust_action_state()" bei mir ein SLOT ist, den man dann auch mit anderen Signalen verbinden kann. Nur wenn eben der SLOT nicht zum SIGNAL passt ( von der Signatur her ) gehe ich den Umweg über einen extra SLOT, der dann adjust_action_state() klassisch als Funktion aufruft.
