@sneubert Thanks :)

@lucaszanella
Do you have a resource file named openglunderqml.qrc ?
Can you refer this example?

Hi,

AFAIK, no. IIRC KDevelop has some stuff already implemented for Docker, but not Qt Creator.

I am using Ubuntu Gnome, add .desktop in /usr/share/applications/

https://developer.gnome.org/integration-guide/stable/desktop-files.html.en

https://forum.qt.io/topic/38166/qt-installer-framework-create-shortcut-on-the-desktop/3

@gizalp
Why do you think python (or anything else) is going to open any terminal window? And what OS are you on anyway?

For QProcess:setProgram you should have process.setProgram("python");, only. But in this case I think it's getting overridden by your process.start("python test.py"); so it doesn't matter, but it's wrong.

If you want to grab a sub-process's output, you have to handle QProcess::readyReadStandardOutput(), and in there something like QByteArray QProcess::readAllStandardOutput(), if that's what you mean by "How can I get the 'Hello' output?".

How this relates to Trying to implement thumbnail list I have no idea....

Hi @huseyinkozan
Yes. It works like a charm.

Mucip:)

@jsulm
well ,Thank you!

Thank you all. The problem is solved I think. I up vote all answers to appreciate your help.

Following what you wrote, it looks like you should rather take a look at QDesktopWidget.

@FrankiPL
I suspect @speeter will have long disappeared, as that post was a year ago :)

Just a thought: have a look at (the first part of) https://raspberrypi.stackexchange.com/a/61086, which claims it's a generic Linux problem rather than just a RPi one. It's not quite the same messages, but worth investigating?

@THEFree
Yep and they also talk about linux there
sudo zypper install libgstreamer-0_10-0
which is same for ubuntu just using apt-get install

And if you have the correct version installed then maybe
sudo apt-get install libqt5multimedia5-plugins
will do it for you.

Thank you dear friend .

You're right . the drivers names were wrong . it works now

Solved, gstreamer-0.10-ffmpeg was missing.

sudo add-apt-repository ppa:mc3man/gstffmpeg-keep sudo apt-get update sudo apt-get install gstreamer0.10-ffmpeg

UPDATE:

Not really solved, using this plugin breaks GStreamer:

How can I fix this problem?

Alright if you say it may couse some problems I think I will install it twice.

How to use "windeployqt" on Ubuntu?

You have two options:

You pack what's needed by hand and don't use the deployment tool at all. You try to run the said tool through wine, which may or may not work.

Cheers!

It looks like you're using the Ubuntu packaged Qt and not the one you installed using the installer.
You should check the Kit in QtCreator you're using.

@SGaist Sure! :)

Try to start your computer and then press Strg-Alt-F1. You then should see the text console (you can go back to graphic mode via Alt-F7). Does the text-console work?

@JKSH Thanks, this link solved my problem.

Hi,
Do you see CONFIG+=qml_debug in your pro file ? which means you have enabled QML debugging (actually it's on by default) . if you remove it then it is disabled.
And just try in release mode.

You can call QWidget::resize() in main.cpp to make your viewer bigger.

I have looked into this myself. You will need to look at UNO and download the SDK for Libreoffice / Openoffice. Once you have this you can automate this software on any platform you want.

I haven't done much beyond the examples provided ( http://api.libreoffice.org/examples/examples.html#Cpp_examples ) since there was no pressing need but I believe this is the answer.

This has nothing to do with Qt but I don't see why you couldn't incorporate this into a Qt program. This should not be an issue.

Re-building the plugin to use your currently installed libmysqlclient_r would be the simple and easy path. Just grab the sources and follow the instruction in the database part of Qt's documentation.

Hi and welcome to devnet,

2 things:

Why this QString::fromUtf8(tr("XXX").toLatin1()) instead of tr("XXX") in QAction constructor ?? Why this mainWindow.menuBar()->addMenu(fileMenu); at the end ??

@kuzulis
I downloaded the versions of gdb and python as mentioned in the script you mentioned . now my project is working fine. I used this link to install gdb .

@SGaist
Thanks for the reply.
The link helped me. I installed libx11-xcb-dev using this .

Thanks for replay, I will try this.

Solved! I had to install kio package via sudo apt-get install kio and now works fine!

Ok, following the wiki worked.

See in the documentation here

Did you name one of your target android ?

I installed g++-arm-linux-gnueabihf and now I can compile for Android.

@jsulm Library file what is very important for building 32-bit?

Hi @PabloAmunt,
packaging for Linux is a major pain in the ass. If you are targeting Ubuntu the place to start is the Ubuntu packaging guide: http://packaging.ubuntu.com/
Good luck!

@mehrdad said:

in publish process there is a part that ask licence file (list of numbers)
first, what is the syntax of this file?

That is an Ubuntu-specific requirement, so most users on this forum don't know the answer.

maybe, i also ask this question in stackoverflow
but i think i have better chance to find a qt programmer that published an app in software center.

The Ubuntu SDK is built on on top of Qt, so most Ubuntu app publishers know Qt. Your best chance is to ask at http://askubuntu.com/

Good luck!
