Removing color gradient window from Qt5 ColorDialog

This is the standard Color Dialog box from Qt5

enter image description here

Is it possible to view the basic colors alone and remove the color gradient from the dialog?

I found simple solution of this problem. It is not a removing, but with my code, we cannot see this gradient and cannot use it.

We need create subclass. Let's code:

mycolordialog.h

#ifndef MYCOLORDIALOG_H
#define MYCOLORDIALOG_H

#include <QColorDialog>
#include <QLabel>

class MyColorDialog : public QColorDialog
{
    Q_OBJECT
public:
    explicit MyColorDialog(QWidget *parent = 0);

signals:

public slots:


};

#endif // MYCOLORDIALOG_H

mycolordialog.cpp

#include "mycolordialog.h"

MyColorDialog::MyColorDialog(QWidget *parent) :
    QColorDialog(parent)
{
    QLabel * l = new QLabel("Teeeeext",this);
    l->setGeometry(245,5,325,215);//this values control the area and position of label
    //you can change this values and remove another area of main dialog window

    QPixmap pixmap("G:/2/qt.jpg");
    l->setPixmap(pixmap.scaled(325,215,Qt::IgnoreAspectRatio));;//resize our picture
    l->show();
}

How to use it???

#include "mycolordialog.h"
//...
void MainWindow::on_pushButton_16_clicked()
{
    MyColorDialog cd;
    cd.exec();
    qDebug() << cd.selectedColor();
}

You can set in label beautiful logo of your app, or something another. I use logo from here http://reichertbrothers.com/images/qt-logo.png , but I convert it into jpg format.

What we get???

enter image description here

Notice, that all another area is available and you can choose any color and work as you want, but this gradient window is remove!!

I hope it helps.

The options that you can select to modify the look of the color dialog are in the QColorDialog documentation. 

    enum ColorDialogOption {
    ShowAlphaChannel    = 0x00000001,
    NoButtons           = 0x00000002,
    DontUseNativeDialog = 0x00000004
    };

This options do not hide the color picker, therefore you will have to implement your custom color picker.
