How to modify QSpinBox appearance

viniltc

Hi All,

I have got a basic question. How to sublcass a Qt object to make some modification in the appearance?

For ex. I need to modify the standard QSpinBox just with the increment/decrement buttons without the value display:

Even though I came across the keyword "sublcass" an object, I never understood systematic way of doing this. It will be very helpful if someone shows the step-by-step procedure to subclass a standard QSpinBox. I started with the following steps, correct me if I'm wrong

Create a class called customspinbox with base class QSpinBox (include QObject and QWidget).
Did following modifications to the customspinbox class:

#ifndef CUSTOMSPINBOX_H
#define CUSTOMSPINBOX_H

#include <QObject>
#include <QWidget>
#include <QSpinBox>

class customspinbox : public QSpinBox
{
  Q_OBJECT
  
public:
  customspinbox(QWidget *parent =nullptr);
};

#endif // CUSTOMSPINBOX_H

In the mainwindow.ui I added a SpinBox and promoted this to the customspinbox class
I speculate the next step will be to override paintEvent function to delete the textBrowser or similar object which displays the spinbox value. But I don't know how to do this.

can you show me how to get rid of the display part of the QSpinBox?

Hi,

Wouldn't it be simpler to create a custom widget with these two buttons ?
It looks like you are about to make your life more complicated than needed.
