Body
monsters.yaml <pre><code>- name: Ogre position: [0, 5, 0] powers: - name: Club damage: 10 - name: Fist damage: 8 - name: Dragon position: [1, 0, 10] powers: - name: Fire Breath damage: 25 - name: Claws damage: 15 - name: Wizard position: [5, -3, 0] powers: - name: Acid Rain damage: 50 - name: Staff damage: 3 </code></pre> main.cpp <pre><code>#include "yaml-cpp/yaml.h" #include <iostream> #include <fstream> #include <string> #include <vector> // our data types struct Vec3 { float x, y, z; }; struct Power { std::string name; int damage; }; struct Monster { std::string name; Vec3 position; std::vector <Power> powers; }; // now the extraction operators for these types void operator >> (const YAML::Node& node, Vec3& v) { node[0] >> v.x; node[1] >> v.y; node[2] >> v.z; } void operator >> (const YAML::Node& node, Power& power) { node["name"] >> power.name; node["damage"] >> power.damage; } void operator >> (const YAML::Node& node, Monster& monster) { node["name"] >> monster.name; node["position"] >> monster.position; const YAML::Node& powers = node["powers"]; for(unsigned i=0;i<powers.size();i++) { Power power; powers[i] >> power; monster.powers.push_back(power); } } int main() { std::ifstream fin("monsters.yaml"); YAML::Parser parser(fin); YAML::Node doc; parser.GetNextDocument(doc); for(unsigned i=0;i<doc.size();i++) { Vec3 v; doc[i] >> v; std::cout << v.x << "\n"; std::cout << v.y << "\n"; std::cout << v.z << "\n"; } return 0; } </code></pre> I thought that, if I modify code analogously, the content of Vec3 will be couted, but it doesn't. What am I doing wrong?

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
