Able to add image file in Qt Design, but image not visible at runtime. Bug?

[Thug]

Hi jsulm,

I'm using free Qt Creator 4.8.1, based on Qt 5.12.1, Win 10 Pro.

My project is a "Qt Widget App" pls see screen below for the option I selected when creating the program.

@Thug Did you check QtCreator bug tracker to see whether this is a known issue? Did you try to disable antivirus software?

Hi,

Might be a silly question but are you sure your .qrc file is compiled ?

[Thug]

Hi @jsulm , I tried disabling McAfee, the "Add Resource" option still freezes. The bug tracker does not seem to show this bug.

@SGaist , are you refering to "Clean project, Run Qmake, Run project" in QT Creator? If yes, I have already tried it. Or do you mean compile qrc via command prompt? How do I select "Add Resource" in command prompt?

I remember the "Add Resource" working, not freezing up 4 days ago when I first installed QT. I did not install anything new nor did any settings since then.

@Thug
You can just edit the .pro file and add the line
RESOURCES += file.qrc
where "file" is the name of your resource file.
As always, when changing the .pro file, make sure that you do a clean/qmake/build cycle.

Hi, @mranger90 the .pro file already included the .qrc line (pls see screenshot below).

A copy of the zipped project file is at:
SG_GUI6

I ran that project on an Ubuntu 18.04 system using Qt 5.12.0
With no modifications, the application built and ran but the wrench was not visible.
In designer mode, the path to the wrench was to my disk - i.e. /home/joem/SG_GU16/Img/Wrench.png.
I changed it to point to the resource entry ":/Res/Img/Wrench.png" in the QLabel/pixmap tab for label_2.
Clean/qmake/rebuild/run and the wrench appears.

[Thug]

@mranger90 , may I ask how do you change the path in Designer mode?

I only see the path
"C:\Users\HG\Doucments\Qt\SG_GUI16\Img\Wrench.png"
when I mouseover the "wrench.png" in the pixmap tab.

Did you select "Choose Resource" or "Choose file"?
I selected "Choose file". When I select "Choose Resource" the program freezes like it is looking for something, I need to press ESC to unfreeze it.

[mranger90]

There are a couple of ways.
the "..." button should give you the option.
or the DownArrow will allow you to choose a resource.
Since the png is already in the resource file, this should work.

Hi
Its not the project it self as it seems to work with same compiler and Qt version.

Have not heard it freezing before when trying to open the resource browse window.
very odd.

Run qmake after adding Image to Resource file

@mrjj oic, then it might be my computer's settings or background programs.
