I've been in the python world lately and python has a dict.update()
https://python-reference.readthedocs.io/en/latest/docs/dict/update.html
It seems that QMap has no such function anymore, but it also never did? unite()
would make a QMultiMap, so there would be multiple entries rather than one.
Which has me asking the question, do I have to provide this myself? Seems a
pretty trivial thing to have to provide?
QVariantMap map_a, map_b;
...
auto combined_map = map_a;
for (const QString& key: map_b.keys()) {
combined_map[key] = map_b[key];
}
Additionally there is no + operator for it, which is actually what I want:
combined_map = map_a + map_b;
But I would be happy with:
combined_map.update(map_b);
Additionally if we're trying to provide as much algebra as possible:
map_a = combined_map - map_b.keys() // remove by matching key
map_a = combined_map - map_b; // remove by matching key-value pairs
In Python, these are doable in a 1-line list/dict comprehension.
Thoughts?
