how can I use the ofParameter helper class from ofxImGui?

[moebiussurfing]

hey @eduardfrigola ,
I tried to include the helpers from ofxImGui to allow add parameters easy...

I added this files:
Helpers.h, Helpers.cpp, (maybe this one could help too: `imconfig.h)

But I am stuck when tried to tweak this method of Helpers.cpp:

//--------------------------------------------------------------
const char * ofxImGui::GetUniqueName(const std::string& candidate)
{
	std::string result = candidate;
	while (std::find(windowOpen.usedNames.top().begin(), windowOpen.usedNames.top().end(), result) != windowOpen.usedNames.top().end())
	{
		result += " ";
	}
	windowOpen.usedNames.top().push_back(result);
	return windowOpen.usedNames.top().back().c_str();
}

It's crashing when adding an ofParameter because it seems related to other classes from ofxImGui and how it handles the window/context...

I have only added #include "Helpers.h" to my project but maybe I must instantiate the class?

Any tip around this?

I made it "work partially" but without handling the names, so all sliders move together...
I just deleted all the code like this:

//Helpers.cpp:

//--------------------------------------------------------------
const char * ofxImGui::GetUniqueName(const std::string& candidate)
{
	std::string result = candidate;
	return result.c_str();
}

And with this app code:

//ofApp:

#include "ofApp.h"
#include "imgui.h"
#include "Helpers.h"

//--------------------------------------------------------------
void ofApp::setup() {

	gui.setup();

	params.setName("myOfParameterGroup");
	params.add(shapeType.set("shape", 1, 1, 2));
	params.add(numShapes.set("num squares", 1, 1, 24));
	params.add(separation.set("separation", 5, 1, 100));
	params.add(shapeSide.set("square side", 50, 5, 200));
	paramsNested.setName("style");
	paramsNested.add(fill.set("fill", false));
	paramsNested.add(color.set("color", ofColor(0, 0), ofColor(0, 0), ofColor(1, 1)));
	paramsNested.add(lineWidth.set("lineWidth", 1, 0.1, 10));
	params.add(paramsNested);
}

//--------------------------------------------------------------
void ofApp::draw() {

	ofVec2f pos(100, 100);

	gui.begin();
	{
		ofxImGui::AddParameter(fill);
		ofxImGui::AddParameter(numShapes);

		auto mainSettings = ofxImGui::Settings();
		mainSettings.windowPos = pos;
		ImGui::SetNextWindowPos(ofVec2f(pos.x, pos.y));

		ofxImGui::AddGroup(params, mainSettings);
	}
	gui.end();
}

It looks like that:
