一、自定义需要弹出的窗口(弹出按钮放在该窗口,且外发按钮信号),注:需要设置背景色,不然弹出是透明的(不知道原因)
二、主窗口初始化
- int m_popBtnWidth = 0;
- int m_beginPosX = 0;
- int m_beginPosY = 0;
- QPropertyAnimation *m_propertyAnimation; //采用属性动画
-
- void RegisterMainWnd::initPopWidget()
- {
- m_popBtnWidth = 40;
- m_beginPosX = this->width() ;
- m_beginPosY = 0;
- m_detailWnd = new RegisterDetailWnd(this); //需要弹出的窗口
- m_detailWnd->setFixedHeight(this->height());
- m_detailWnd->setMinimumWidth(this->width() / 2);
- m_detailWnd->move(m_beginPosX - m_popBtnWidth,m_beginPosY);// 初始化将其放到主界面最右侧停靠
- m_curPopStatus = false;
- connect(m_detailWnd, &RegisterDetailWnd::popStatusChanged, this, &RegisterMainWnd::onPopStatusChanged); //连接信号
-
- m_propertyAnimation = new QPropertyAnimation(m_detailWnd,"geometry"); //初始化动画
- m_propertyAnimation->setEasingCurve(QEasingCurve::InOutSine);
- m_propertyAnimation->setDuration(800);
- }
三、按钮信号处理
- void RegisterMainWnd::onPopStatusChanged(bool pop)
- {
- if(pop) //从最右边弹出,
- {
- m_propertyAnimation->setStartValue(QRect(m_beginPosX - m_popBtnWidth,m_beginPosY,m_detailWnd->width(),m_detailWnd->height()));
- m_propertyAnimation->setEndValue(QRect(m_beginPosX-m_detailWnd->width(),m_beginPosY,m_detailWnd->width(),m_detailWnd->height()));
- m_propertyAnimation->start();
-
- }
- else //回到最右边
- {
- m_propertyAnimation->setStartValue(QRect(m_beginPosX-m_detailWnd->width(),m_beginPosY,m_detailWnd->width(),m_detailWnd->height()));
- m_propertyAnimation->setEndValue(QRect(m_beginPosX - m_popBtnWidth,m_beginPosY,m_detailWnd->width(),m_detailWnd->height()));
- m_propertyAnimation->start();
-
- }
-
- }
三、重置弹出窗口与主界面宽度一致
- void RegisterMainWnd::resizeEvent(QResizeEvent *e)//重写主界面的事件
- {
- m_beginPosX = this->width() ;
- m_beginPosY = 0;
- m_detailWnd->setFixedHeight(this->height());
- m_detailWnd->setMinimumWidth(this->width() / 2);
- m_detailWnd->move(m_beginPosX - m_popBtnWidth,m_beginPosY);// 右侧停靠
- QWidget::resizeEvent(e);
- }
