[SOLVED] std::string and Q_PROPERTY()

ASxa86

I am unable to get std::string properties for my custom widget to appear in QtDesigner.

Below is an example of the code i'm running that isn't working. Any suggestions?

@
// CustomCheckBox.h
#pragma once
#include <QtWidgets/QCheckBox>

#include <string>

Q_DECLARE_METATYPE(std::string)

class CustomCheckBox : public QCheckBox
{
Q_OBJECT
// this property does NOT appear in QtDesigner
Q_PROPERTY(std::string name READ getName WRITE setName)

 public:
      CustomCheckBox(QWidget* parent = nullptr);
      virtual ~CustomCheckBox();

      void setName(const std::string& x);
      std::string getName() const;

 private:
      std::string name;

};
@

@
// CustomCheckBox.cpp
#include "CustomCheckBox.h"

CustomCheckBox::CustomCheckBox(QWidget* parent) : QCheckBox(parent)
{
// doesn't work
qRegisterMetaTypestd::string();

 // doesn't work
 qRegisterMetaType<std::string>("std::string");

}

Hi,

std::string is a template specification (some kind of typedef).
I think that Q_PROPERTY doesn't workfor templates (check on the documentation).

Anyway IMHO it's better to use QString as property.

I...should have known that. Thank you. Using QString will probably be what I do now.
