ImNodes
=======
A standalone [Dear ImGui](https://github.com/ocornut/imgui) node graph implementation.
Library provides core features needed to create a node graph, while leaving it to the user to define content of node.
Node layouting is left to the user, however comprehensible example is available which can be used as a base.
## A (very) trivial example
```cpp
static ImNodes::CanvasState canvas;
if (ImGui::Begin("ImNodes", nullptr, ImGuiWindowFlags_NoScrollbar | ImGuiWindowFlags_NoScrollWithMouse))
{
ImNodes::BeginCanvas(&canvas);
struct Node
{
ImVec2 pos{};
bool selected{};
ImNodes::Ez::SlotInfo inputs[1];
ImNodes::Ez::SlotInfo outputs[1];
};
static Node nodes[3] = {
{{50, 100}, false, {{"In", 1}}, {{"Out", 1}}},
{{250, 50}, false, {{"In", 1}}, {{"Out", 1}}},
{{250, 100}, false, {{"In", 1}}, {{"Out", 1}}},
};
for (Node& node : nodes)
{
if (ImNodes::Ez::BeginNode(&node, "Node Title", &node.pos, &node.selected))
{
ImNodes::Ez::InputSlots(node.inputs, 1);
ImNodes::Ez::OutputSlots(node.outputs, 1);
ImNodes::Ez::EndNode();
}
}
ImNodes::Connection(&nodes[1], "In", &nodes[0], "Out");
ImNodes::Connection(&nodes[2], "In", &nodes[0], "Out");
ImNodes::EndCanvas();
}
ImGui::End();
```
