QUESTION
I have searched a lot for this topic and already found some approach but I get some errors I can't find the reason of it.
Idea is to read the keys from the enum with QMetaEnum to fill the strings in a combobox later.
I have already the enum and also setup Q_Object and Q_Enum Macro in the class where the enum is. But I am getting "undefined reference to 'Planet:: metaObject() const'" error message by using the QMetaEnum.
Here is the planet.h

I am learning C programming from "Learn c the hard way by Zed Shaw". He asks the learner to try and break their own code.
So I tried the following C code and thought printing more values that I gave argv will break it but it did not until later.
...ANSWER
Answered 2021-May-30 at 09:48A segmentation fault happens when the code try to access a memory region that is not available.
Accessing an array out of bounds doesn't means that the memory before or after the area occupied by the array is not available: The compiler or the runtime usually put all varibales or data in general in a given block of memory. If your array is the last item of such a memory block, the accessing it with a to big index will produce a Segmentaion Fault but is the array is in the middle of the memory block, you will just access memory used for other data, giving unexpected result and undefined behavior.
If the array (In may example, but valid for anything) is written, accessing available memory will not produce a segmentation fault but will overwrite something else. It may produce unexpected results or crash or segmentation fault later! This kind of bug is frequently very difficult to find because the unexpected result/behavior looks completely independent of the root cause.

function as well as the angle calculation entirely in your JavaScript callback. It is not clear what you are trying to achieve with your code but here is some example JS callback implementation based on your code that changes the pie angle (tested with Bokeh v2.1.1):

When I run this, the scatter_mapbox colorscale is set to the same properties as the choropleth_mapbox properties. Namely, it uses the color scale Viridis instead of Picnic and uses the choropleth's numerical scale. How can I make the the colorscale for the scatterplot Picnic.
