Icons are not visible when installing Qt application on end user machine(Windows) Why?

Franzk

Still, it's more of a deployment issue. Also, having the same conversation in two places will be confusing. Don't double post.

swhweng

Ok
You understand the thing another
So what do you think why such a problem?

Franzk

Standard Qt SDK contains a number of plugins you may not be aware of. Check the $QTDIR/plugins directory.

What is the type of image you use? How do you reference the icons in your code? Did you use designer or do you hand code them? Did you use the correct path -- it is possible to forget the : and still have the icons in your development build due to amazingly conveniently coincidentally similarly named paths.

Franzk

It's a general rule/guideline on a lot of forums, and has been for a long time. This is not without reason. The confusion might not be here now, but it might come in the future, when people start searching through old posts.

Thank you very much for your reply
I do not know did not hear that there is need for additional plugin so as to add ans see icons
I add my icons in Qt Designer, before that I add them to resource file
The path is ok while I compile and launch the application on machine when it built and I see icons in there places when I've put them while developing?
A put .exe, .rcc and dlls to end user and I see no icons?

swhweng

See Qt Reference Documentation
There is anything about you sould use any plugin so as to manage resources
look at
Qt Reference Documentation – the Qt Resource System

there is wrote all should be ok, but the icons still invisible when installing...

I have tried also to deploy with dlls from plugins/codecs , plugins/imageformats, plugins/iconengines but still I can't see icons
I can see only when I install full Qt SDK and I deploy to qt/bin directory
But we understand the end user should not install full Qt SDK so as to use application
why such a problem?>

What's the image type of your icons?

Just merged the two identical threads into one.

Hi Volker
Thanks for your reply man
my icons formats are .ico, .jpeg, .png
why do you ask?

goetz

If you do not have installed the imageformat plugins correctly, your application is not able to display them (nor any other jpeg, png or ico image).

You must maintain the directory hierarchy of the plugins like in the Qt install dir and you might want to add the plugin dir to the library path (use "QCoreApplication::addLibraryPath() ":http://doc.qt.nokia.com/4.7-snapshot/qcoreapplication.html#addLibraryPath).

swhweng

Yea
sure
but the plugins are installed when I install standart Qt SDK from the site ( open source )
Now I try to include imageformats and iconenginer folders with dlls with my .exe and the dlls when I deploy
Lets see how it installs

goetz

Of course you must provide copies of that files in your installation package, as well as the Qt libs.

Hello
I deployed today with /plugins/imageformats folder
It works only when I deploy may application exe, main Qt dlls as I mentioned and imageformats folder on windows
Also I looked at Process Monitor output for my application and I see there that my application uses also QtSVG4.dll, QtXML4.dll but I think it is because resources are in xml format...
How can I deploy on MacOS, Ubuntu, Symbian , Maemo?
Thanks
Pavel

Yes. Everyone told you exactly this.

Read the docs, search the forum and wiki, ask google and come back with actual questions.

For OS X: the docs provide sufficient information.

For Ubuntu: create a deb.

For Symbian, Maemo: have a look at forum nokia and the docs for the respective platform.

swhweng

Thank you all
I succeed to deploy on Win7 using your advices
I currently work on deploying to another platforms
creating .sis installer

Hi, I'm sorry to bring up this old topic.
I had the same problem and thanks to this thread I've fixed my icons. :)
However I need to know if there is a way to determine which plugins EXACTLY does my application require, so i don't have to include all the plugins in my installation package?
Thank you in advance!

tzander

dv879: have you tried to install the pugins one by one until everything works?

dv879

The project is HUGE and I can not determine if everything works the way you are suggesting. And there should definitely be a more "intelligent" way. :)
I wanted to know if there are some kind of dependencies records, where I can check on which plugins depends my program...
