Hi
Im out of idea what could be wrong.
It does draw the widgets and such, its just images that dont show ?

[Platinum Lucario]

@mrjj Yeah, same here, I tried reinstalling Qt (all of it, including the entire Qt folder), and I still have the same problem.

[mrjj]

Hi
Its pretty odd.
I tried the porymap on 2 different pc and it just worked so clearly something local
at your pc but the normal suspect gfx driver etc seems not to apply.

So when you reinstalled. did you try taking ONLY the mingw version ?

and nothing else ?

[Platinum Lucario]

@mrjj I've tried with both installing everything and tried installing only the mingw version, still the same result

@Platinum-Lucario
can you upload that test project somewhere?

[mrjj]

@J-Hilk
I think its this one

@Platinum-Lucario
Do you have any special anti virus running that might block rcc.exe silently ?

[Platinum Lucario]

@mrjj The only anti-virus I have, is the built-in Windows Defender, does it actually block rcc.exe silently?

[mrjj]

@Platinum-Lucario

Not seen that happen in winver 1803 or heard about that. only avast and other
non native.

When you compile and run restest
are those file generated in the build folder ?

[Platinum Lucario]

@mrjj Here's what appears in the restest debug folder:

[mrjj]

@Platinum-Lucario
Ok super so rcc runs it seems and the file seems valid/has size.
So it must be related to the image plugin somehow.

Have you tried to load a image using a path and see if that shows ?

[Platinum Lucario]

@mrjj Okay, so I tried reselecting the .jpg in the project, and it came up with an error as seen below. But when I selected a .png image, it worked just fine. So I wonder why it's not allowing .ico and .jpg (or even not having them appear in the Choose a Pixmap window)?

[Platinum Lucario]

I'm still curious as to why the plugins aren't working

[mrjj]

@Platinum-Lucario

Im also very puzzled about that since its both mingw and visualstudio's version
so i am guessing on its something they both load that makes them fail somehow.

[Platinum Lucario]

@mrjj I know I have Visual Studio 2017 Community Edition installed, but surely this wouldn't prevent Qt Creator from loading the plugins, right?

well the Creator is compiled with vs and its runtime could affect it but
that should cause more global issues than just jpg and ico not working.

try to search your installation for qjpeg.dll and see if some app also installed a version.

And as for the imageformats plugin folder, it's there:

This is not the folder you want. This folder contains development plugins for the apps that you build.

Your issue is that Qt Creator can't read the icons. Qt Creator is a Qt-based application too, and it uses its own plugins (not your development plugins).

1. Check C:\Qt\Tools\QtCreator\bin\plugins\imageformats\ to make sure that qico.dll and qjpeg.dll are there
2. Try to open the resource editor again. When the window is open, use ListDLLs (https://docs.microsoft.com/en-us/sysinternals/downloads/listdlls ) to see which DLLs are loaded by Qt Creator. Do you see qico.dll and qjpeg.dll in the list? Are they loaded from the correct folder?

This is the files listed in the directory you mentioned, anything missing that requires it to work?

And of course, I ran ListDlls64.exe with the commands -r -v -d qjpeg.dll and this was the result:

And I ran ListDlls.exe with the same commands, and this was the result:

I ran them both as Administrator.

I don't see Qt Creator in your screenshots.

1. Launch Qt Creator and open the resource editor.
2. Run ListDLLs64.exe QtCreator

I suspect that you'll see Qt Creator using plugins from a different folder instead of C:\Qt\Tools\QtCreator. Remove that other folder from your global PATH.
