child.h

#ifndef WRAPPER_H

#define WRAPPER_H
#include <QWidget>
#include <QFrame>
#include <QKeyEvent>
#include <QHBoxLayout>

class Ping;

class Wrapper : public QWidget
{
    Q_OBJECT

public:
    Wrapper(QWidget * parent=0);
    Ping * pingWidget;
    int resizedWidth;
    int resizedHeight;
    QHBoxLayout * hbox;
protected:
    void keyPressEvent(QKeyEvent *);
    void keyReleaseEvent(QKeyEvent * e);
    void  resizeEvent(QResizeEvent * e);
private:

};

parent.cpp

class Ping : public QWidget
{
Q_OBJECT

public:
    Ping(QWidget * parent=0);
    ~Ping();
    int w;
    int h;
    void keyPressEvent(QKeyEvent *);
    void keyReleaseEvent(QKeyEvent *);
protected:
    void paintEvent(QPaintEvent *);
    void timerEvent(QTimerEvent *);
...
        };

在网络上的一个答案中，我发现我需要将此代码放在paintEvet上，所以我这样做了 - 无论是父母还是孩子。

Wrapper::Wrapper(QWidget * parent) : QWidget(parent)
{
    setMinimumSize(300,400);
    setGeometry(100,100,300,400);


    pingWidget=new Ping(this);
    pingWidget->setStyleSheet("QLineEdit { background-color: yellow ;};");
//doesn't work
        pingWidget->move((width()-300)/2, (height()-400)/2);
    setStyleSheet("QLineEdit { background-color: yellow ;};");
//doesn't work  




    //QPushButton * b1=new QPushButton(this);
//if i add the button and change its color - it works     
this->setStyleSheet("background-color: red;");


  //  user1->setGeometry(width()/10, height()/10, );



}

但仍然没有进展。我该怎么办？

Setstylesheet对于父母和孩子都不起作用
