QT左右弹窗控件

QT自定义控件(左右方向弹出控件)

自定义控件存在的意义 ：QT 内置控件丑，而且满足不了有些实际开发的需求。所以需要编写自定义控件来完成一些特殊需求。

效果展示

1. 界面说明 ：点击右侧中间的按钮会从左边或者右边弹出一个窗体，这个窗体还可以自定义。
2. 功能说明 ：单击按钮窗体弹出，再次单击窗体消失
3. 补充说明：弹窗可自定义成任意控件。亦可以设置按钮与弹窗之间的 距离

代码:

class myButton : public QToolButton
{
   Q_OBJECT
public:
   explicit myButton(QWidget *parent = nullptr);
    ~myButton();
   //myButton(QWidget *parent = nullptr,int pos=0);
public:
   void initWidgetInfo();
   void createTool(toolWidget*tools);
   void mousePressEvent(QMouseEvent *);
   void moveEvent(QMoveEvent *);
   void hideEvent(QHideEvent*);
   void setListParent(QWidget*parent);
   void setItemWidgetPos(int pos);
   void setSpacting(int spacing);
   void dealWithAnimation();
   void printPos();
signals:

public slots:
