Brainstorm

@tekojo Thanks a lot bro. I think i got the right link :)

@Bharathi Thanks a lot :)

Actually, my idea is to have a storage of different wooden blocks in user interface and drag them one-by-one to working area to design a house model and then generate a txt file containing the stream of the coordinates (including some other attributes like color, shape) of building blocks.

You'll likely have build your avframe with the data contained by the QByteArray

@Edin-M but there would still need to be DB_TABLE macro, just without arguments. Why, what exactly is that macro supposed to do? As for column names, acctually I use properties, so columns are same as property name so DB_COLUMN(QString, name) creates set_name() and get_name() methods Look up Q_PROPERTY. One thing I'm unable is to retrieve list of all QObjects in a system And why should you? There's no central repository for objects ... Besides QObjects are not for that, they can't be copied, you should just use regular objects. And my point was that you don't need to have any macros besides Q_GADGET (which will allow to query for the class name with some tweaking) and Q_PROPERTY (which will give you dynamic properties). The relations can be retrieved from the db.

Hi, Do you mean something like the RSS feed ?

@Maxim-DC but what if that data isn't that stupid like "txtdata" but something more like progress in a game, how to save this? Another approach for this could be QSettings with a custom format. You could set a reader and a writer function that writes encrypted data into a file. QSettings::Format newformat = QSettings::registerFormat("cnf",read,write); settings = new QSettings("cnf/u.cnf",newformat); bool read(QIODevice &dev,QSettings::SettingsMap &map) { //your code goes here return true; } bool write(QIODevice &dev,const QSettings::SettingsMap &map) { //your code goes here return true; } For not so strong encryption you could use Simple Crypt in your read and write functions

Hi, while I think you're correct about QComboBox, for QListView I think you can apply individual stylesheets to it. If you can use a QListWidget instead I have an example: for (int i = 0; (i < 10); ++i) ui->listWidget->addItem(new QListWidgetItem("")); QLabel* l1 = new QLabel("Item1",this); l1->setStyleSheet("* { color: #FF0000; }"); ui->listWidget->setItemWidget(ui->listWidget->item(0),l1); QLabel* l2 = new QLabel("Item2",this); l2->setStyleSheet("* { color: #00FF00; }"); ui->listWidget->setItemWidget(ui->listWidget->item(1),l2);

Hi @I-d-na, To clarify @SGaist's point: QImage is not an image format. It is a C++ class that lets C++ programmers manipulate images. A QImage cannot be downloaded over the internet. A QImage can only exist in a program that's written with Qt. File names like "main-qimg-salad" are not related to QImage. (Yes, I know the both start with a 'Q' and end with "image/"img", but really: they are not related at all.) Now that we've cleared that up, let's get to the root of your problem. If you download a file and it's called "main-qimg-salad", it simply means that the server gave it a filename that starts with "main-qimg", but the server neglected to include the .filetype extension at the end. Therefore, we can't tell what type of image it is. See https://www.quora.com/Why-do-we-get-main-qimg-e7b0b4951d663c737e5bbf2722d23612-jpg-types-of-saving-titles-when-we-download-images-from-the-Internet for a discussion of this naming system. If you search https://www.google.com/search?q="main-qimg" you will find that most of these images are actually JPEG files. So, try renaming your file from "main-qimg-salad" to "main-qimg-salad.jpg" and see what happens.

Thank you for your support.:-)

Sounds good !

I've never used one but I know the device. You should try to contact the VLC team to see with them how they proceed with the UPnP/DLNA part.

Thanks for all responses, so far. (I'd like to keep this question open, in case anyone has other ideas on other options, and stuff). I posed a question about a Qt5-only solution vaguely suggested in a related forum: Getting QImages into QMediaRecoder to create video files (e.g. avi, mp4, or animated gif)? ... https://forum.qt.io/topic/63258/getting-qimages-into-qmediarecoder-to-create-video-files-e-g-avi-mp4-or-animated-gif --

Hi and welcome to devnet, What exactly are you trying to send over your serial port ? In any case, the maximum size of what is sent at a time is 8bit but that doesn't mean you can't send complex structures over it.

One semi-nice way comes to mind. You could use QFontMetrics::elidedText to get the part that fits in a line. The downside is that you would get the text with "...", but you can measure the width of "..." first, add that width to the maximum line width for measurement and then remove the dots from resulting string.

Hi, It's all explained here

I am developing a framework that works similar like rails in Qt: https://github.com/cybercatalyst/qtwebserver

@dridk said: The real goal is to have an alternative of html. Imagine a Web browser with qml page only. It would be cool to see QML used for web apps. Someone has made a start on this: http://akreuzkamp.de/2013/07/10/webapps-written-in-qml-not-far-from-reality-anymore/
