    Hi, as I said in the other thread, I think your isn't an optimal solution: what's happen if 2 tables aren't enough to show all your data? Could you show a mockup of your solution?

    Yes the idea is to have the same qml file ( more or less - I'm still investigating if this is possible ) on each device and each device renders the part for its screen. I think this is easily achievable when the qml has static parts and no animation. I trying to figure out how to make it work when you have animation, simple example: a square that moves horizontally from one to screen to the next... In my example I have a timer that every second moves the rectangle of 10pixel to the right, to make everything work I need to have the two timers of the two devices synchronized... and this is what I'm trying to look in the sources of Qt.... Your idea could be a solution, do you think its feasible? The problem is that when you have a big videowall ( 3x3 or 4x4 ) I don't think a single computer has the power to render at a decent frame rate the whole setup..

    Hey, I just made a little research and what I found so far: Watch for an added file with QFileSystemWatcher::directoryChanged and printing with QPrinter. I will now try to use those classes and see how far I can get. I then want to show the file that just has been added to the directory with QImage and QLabel. Is there a better way to do this? The button should then be a QPushButton with set alpha value. I will give it a try :) Thank for any comment :P Best, JRS

    [quote author="MichelS" date="1372661838"]Thanks for sharing. I haven't thought of this yet, but it sounds reasonable. Although I'd avoid it to delete objects in slots connected to their signal.[/quote] In the Tufão documentation, I've used to put several paragraphs explaining how to properly use unsafe signals and this info would have to be in every unsafe signal. After introduce the concept of unsafe signals, the how to use an unsafe signal became a reference to a page that is clearer and simpler.

    I have posted it on stackoverflow.com and i got the answer. The path shouldn't be "C:/", but "My Computer". @model->myComputer().toString();@ It solves the problem. I have posted the answer here, because maybe someday someone will have the same problem and he will get here looking for help.

    I'm using windows 7 currently with MinGW. Thanks for the blog reference. Unfortunately none of the blog links are valid but I think it may provide a roadmap to something useful.

    [quote author="qxoz" date="1363178482"]I am ashamed to admit but I didn't hear about Prezi before. As i understand it is a alternative for PowerPoint? I think for apps like this, QtQuick can be better choice. What do you think?[/quote] QtQuick is also a better choice. But for a developer who specializes in C++, they can work better in a language where they can harness their full potential... Way better if both QML and Qt/C++ are supported. :)

    Ok, thank you very much. I was searching for something like BSA for hours on Polish, Spanish and English Google and I don't know how it's possible that I haven't found it. The day when I will make my first money, I will spend it on a beer for you! (or five beers :D)

    Nope: These will be probably provided by enhancements to KDE Shortcut system, and by enhancing shortcuts within the Window Manager (KWin).

    Okay, thank you, that sounds like a good plan. I changed the border size, but there is still a pixel (maybe two) between the border of the QWidget and the QTabWidget
