When I pass the code to Windows the icons are black and white

serkan_tr

I designed the screen using Qt in Linux. And the codes worked without any problems. I built the same system in Windows environment but this time the system did not work as I expected, the icons turned black and white and the buttons did not work properly, what is the reason for this?

(In Linux environment the buttons work properly, the button I press only appears bright, but in Windows this feature does not work properly.)

Thank you for your answers

I didn't fully understand the problem but I solved it. Because button usage works differently in Windows and Linux for some reason (maybe because of the Qt version)

This is the code that works in Linux

Seems like the icons couldn't be found...
Check if your paths are correct.

@Pl45m4 shapes were formed. The shapes have no colors If the path was wrong then the shapes would not have formed.

Put those icons in the resource file, then you can reference them with an identical path on every platform.

This part works correctly in Linux but not in Windows. The signal slot mechanism is not triggered in this part.

You post in General and Desktop, for Qt widget programs, but your screenshot is clearly QML. So which are you using?

Although I know nothing about QML, you have chosen to specify external files (rather than resource files) by path and have used a relative path, right? So what makes you think the ../..... will reference the same file/directory under both OSes? Assuming QML treats them as relative to the current directory (does it?) what is that when you run the QML application on each platform and why do you assume they will be the same?

You might consider earlier suggestion:

I have no idea what "The signal slot mechanism is not triggered in this part" has to do with anything.

... so put the images into a Qt resource file to make sure they are found.

UPDATE
Yes, I see what you mean.

First do either of:

Change to Qt resources. Does that make any difference?
Change your existing paths to deliberately-non-existing, like rubbish/assets/..., so you are sure it is wrong. Does that make any difference?

If these produce same result, i.e. correct shapes but black & white, then it does indeed seem you have some trouble correctly rendering colored icons on the platform. I don't know why that should be. Check the properties of the .png files, do you have to install anything like a PNG library to make things work? Maybe try, say, a .jpg or .gif for one of them and see how that renders?

@serkan_tr it's not the in the Qt resource file so location might change depending on OS.

This: "../assets/icons/home.png" is not a uniform path across the operating systems. An effect of which you just experience.

In some Qt Quick Controls styles the icon are rendered in monochrome. Linux has a different default style than window.
