Hi,

Did you check that you have all dependencies required for the freeglut .dll if any ?

Hi and welcome to devnet,

Why not use a layout for that ?

@SGaist

Thanks for the question.

That made me search for the function. I had never implemented a function by that name.

Searching, I found the reference in mainwindow.h, private slots.
I have no clue, how it landed in there.

Removing it , fixed the issue.

Argh, I was really pulling out hair.

Thanks!

Manu

Hi,

Did you just clone the curl sources ? If so the you have to build it before you can use it.

Hi
I would try a normal QML example and see if all is as it should be.
The warnings/erros sounds like you dont have QML installed.

You might need to install Qt with the online installer if you have not already done that.

I realise that your question is a few months old. However I'd like to clarify and answer for you or anyone who may come across this in a google search as I did.

Your question is basically 4 questions:

1) Can one use the (largely) LGPL OpenSource QT to edit GPLv2 Source Code?
A. Yes. If you distribute a binary, as per LGPL you must provide a way for the recipient to re-link the binary with their own or different versions of the libraries provided by QT. GPLv2 code CAN be linked to an LGPL library. In this sense they are perfectly compatible..

2) Do you need to distribute any source code?
A. Yes. You must re-distribute your modified GPLv2 Source. It doesn't have to be GitHub, but anyone who gets a binary from you must be made aware of where to get sources.

3) Does using a commercial version of QT release you from your obligation?
A. Yes and No.

No, because GPLv2 does not allow any modifications to be held under any other license but GPLv2, so you are obligated to follow those guidelines irrespective.

Yes, because you no longer need to keep up with QT's LGPL guidelines, you can choose to not distribute any changes you make to a QT Library and/or not provide a relinking mechanism.

4) Can you charge for your effort?
A. Yes. Whether you go OpenSource or Commercial you can charge your client.

Hi, and welcome!

@fangyu said in Can qt integrate with software developed by tk:

I have a program written in tk, and I want to access its window through qt.

Can you describe what you mean by "access its window through Qt"? Are you trying to control the other window from a Qt application?

Can be obtained through "findwindows" in the windows system, so is there a similar API in the ubuntu system.

You could get the window ID (see https://stackoverflow.com/questions/151407/how-to-get-an-x11-window-from-a-process-id for example), and then call QWindow::fromWinId() (see https://doc.qt.io/qt-5/qwindow.html#fromWinId)

However, this is not properly supported so you might not be able to do everything you want.

can qt integrate with the software developed by tk?

Not directly.

Hi
Yes that was what i meant. maybe badly explained.
In linux, even the actual file name does start with libXX, then you
do not included when used as link name. and just use XX

Hi,

As a first step, use this QImage constructor to create a QImage object that you will set on a QLabel.

Once you have that, then you'll be able to go further.

@naeco2005 Looks like ICU is optional, see https://doc.qt.io/qt-5/windows-requirements.html#icu
Also, if you have a commertial license you can ask QtCompany for support.

Many thanks for the confirmation.

@m-manirul You really expect exact answer for each of these libs?!
Why do you actually want to know that? For most of these libs many versions will work, so how can anybody give you an exact answer?
Just try to build for your system.
The only important part here is OpenSSL, I think for Qt 5.5 you need v1.0.x
HTTPS is not a lib but encrypted HTTP.

Hi,

You should give more details about what you are doing, what this is about, what OS you are running, in what way is it related to Qt, etc.

@abuabdellah From http://ppa.launchpad.net/ubuntu-sdk-team/ppa/ubuntu/dists/ I can see that Ubuntu 19.10 (eoan) is not supported. It looks like latest Ubuntu version there is 17.04. I'm not even sure Ubuntu Touch is still in development? I was thinking it was stopped by Canonical.

Thanks for the feedback !
