今天给大家讲解基于C++/Qt的CQGUI框架的阴影圆角
窗口实现，实现效果如下图所示：：
window.open('http://www.qtcn.org/bbs/attachment/Mon_2103/17_208164_4c2ef28c0daf092.png?177');" style="max-width:700px;max-height:700px;" onload="if(is_ie6&&this.offsetWidth>700)this.width=700;" >CQGUI开发环境：：- Microsoft Visual Studio 2019
- Qt5.15.1
步骤如下：：一、继承关系 class LoginPanel :
public QDialog
二、窗口属性 setAttribute(Qt::WA_TranslucentBackground);
//设置顶层面板背景透明setWindowFlags(Qt::FramelessWindowHint);
//设置无边框setContentsMargins(10, 10, 10, 10);
Qt::WA_TranslucentBackground Indicates that the
widget should have a translucent background, i.e., any non-opaque regions of the widgets will be translucent because the widget will have an alpha channel. Setting this flag causes WA_NoSystemBackground to be set. On
Windows the widget also needs the Qt::FramelessWindowHint window flag to be set. This flag is set or cleared by the widget's author.
三、设置阴影效果 auto *defaultShadow =
new QGraphicsDropShadowEffect();defaultShadow->setBlurRadius(10.0);defaultShadow->setColor(QColor(0, 0, 0, 160));defaultShadow->setOffset(0, 0);_loginMainFrm->setGraphicsEffect(defaultShadow);
四、设置样式 QFrame#loginMainFrm>
QFrame#leftFrame{
background:
rgba(255,255,255,0.9);
border-top-left-radius:6px;
border-top-right-radius:0px;
border-bottom-right-radius:0px;
border-bottom-left-radius:6px;}
五、事件响应 protected:
void mousePressEvent(QMouseEvent *e)
override ;
void mouseReleaseEvent(QMouseEvent *e)
override ;
void mouseMoveEvent(QMouseEvent *e)
override ;
void closeEvent(QCloseEvent *e)
override ;
bool event(QEvent* e)
override ;
protected:
bool eventFilter(QObject* o, QEvent* e)
override;
