Minimal, Complete and Verifiable Example code:
Consider:
struct Text {
Text(const std::string& label, const std::string& str) :label(label), str(str) {}
void update() {
ImGui::InputText(label.c_str(), &str);
}
std::string label;
std::string str;
};Initialization with:
Text t1("", "Text1");
Text t2("", "Text2");And updating with:
t1.update();
t2.update();
