I’ve tried a number of things to add a resource and use an icon with a button. I’ve noticed I can access Slicer resources, but not ones in the Resources folder of my module. I’d like to do the following, hopefully with a relative path as opposed to absolute, with the icon file in the Resources/Icons…

Thanks very much everyone. I currently have it working with this in the CMakeLists.txt: set(MODULE_PYTHON_RESOURCES Resources/Icons/${MODULE_NAME}.png Resources/Icons/SSFPIcon.png ) And this in my module Widget class: moduleDir = os.path.dirname(slicer.util.modulePath(self.__module__)) …

You can do this: iconPath = os.path.join(os.path.dirname(self.parent.path), ‘Resources/Icons’, ‘SSFPicon.png’) icon = qt.QIcon(iconPath)

Thanks, I can see where you’re going with this, though when I tried it, self.parent.path was not recognized. What am I missing?

I think part of the problem is that I’m trying to use it from the Widget class. I’m looking at ScriptedLoadableModule.py and I see that self.parent.path works from the module class.

I’m currently trying the following, but the image still does not show in the button: moduleDir = os.path.dirname(slicer.util.modulePath(self.__module__)) iconPath = os.path.join(moduleDir, 'Resources/Icons', 'SSFPicon.png') icon = qt.QIcon(iconPath) Is there something else missing? Th…

Did you verify that the path actually points to the image? For example you need to install the image file to the build directory as well. A working example: https://app.assembla.com/spaces/slicerrt/subversion/source/HEAD/trunk/GelDosimetryAnalysis/src/GelDosimetryAnalysis/GelDosimetryAnalysis.py#ln…

I’ve checked the value of iconPath, and it points to the image. What build directory do you mean? I’ve looked at the code you referenced, and what I have is consistent. A possible difference may be that I’m using an additional image, rather than the one that was defined when the module was created.…

I said all I know. Please try to work with this example and see what is in it that is not present in your module. One of those differences will be what causes your image not to show up. The qrc file is a good starting point.

Ok. Thanks for trying. If you think of anything else, let me know.

There are many examples for using custom icons in widget classes. For example: https://github.com/SlicerIGT/SlicerIGT/blob/b05132759b32ae3a2d3e52e9897dd28f7a39677d/PlusRemote/PlusRemote.py#L55 Using qrc file is a bit more complicated, because you need to compile resources and for that probably you …

Yes, this is basically the same method. What you’ll need to make sure is that the icon file is properly deployed with your module.
