+  to get more info about how to do things.
 * In places where in C++ you need to pass `ImVec2` or `ImVec4`, you'll need to pass two or four float parameters respectively.
 * When you need to get an output from the Dear-ImGui use wrappers for primitives: `ImBool`, `ImInt` etc.
+* Due to the Java and JNI restrictions we can't provide a fully fledged callbacks to the ImGui::InputText*() methods.
+  Partly you could replace some of the features (like providing of the allowed chars to input) by using the ImGuiInputTextData class. Read javadoc to get more info.
