先看效果:
在进行多进程开发时,可能会遇到需要进行全局弹窗的需求。
因为平时会使用ToDesk进行远程桌面控制,在电脑被控时,ToDesk会在右下角进行一个顶层窗口的提示,效果如下:
其实要实现顶层窗口,最关键的是设置窗口属性:
cpp
setWindowFlags(Qt::FramelessWindowHint | Qt::WindowStaysOnTopHint);
同时一般也不太需要Windows状态栏的图标,我们可以这样,加一个Qt::Tool上去:
cpp
setWindowFlags(Qt::FramelessWindowHint | Qt::WindowStaysOnTopHint | Qt::Tool);
动画效果的使用,会使程序的呈现更加奈斯:
cpp
// 初始化
{
moveAnimation_ = new QPropertyAnimation(this,"pos",this);
QScreen *primaryScreen = QGuiApplication::primaryScreen();
if(primaryScreen==nullptr) { return; }
geometry=primaryScreen->availableGeometry();
this->move(geometry.width()-300-pix_right_.width(),geometry.height()-200);
setFixedSize(300+pix_right_.width(), 200);
}
// 调用
{
QString imageName = is_expanded_ ? "right" : "left";
QPoint showPoint = QPoint(geometry.width()-300-pix_right_.width(),geometry.height()-200);
QPoint hidePoint = QPoint(geometry.width()-pix_right_.width(),geometry.height()-200);
if(is_expanded_) {
startAnimation(showPoint, hidePoint);
btn_->setMask(pix_right_.mask());
} else {
startAnimation(hidePoint, showPoint);
btn_->setMask(pix_left_.mask());
}
}
// target目标点,oldpos起始点
void AssistDlg::startAnimation(QPoint target, QPoint oldpos)
{
moveAnimation_->setDuration(300);
moveAnimation_->setStartValue(oldpos);
moveAnimation_->setEndValue(target);
moveAnimation_->setEasingCurve(QEasingCurve::OutCubic);
moveAnimation_->start();
}
不规则按钮的主要代码如下:
cpp
btn_ = new QPushButton(this);
btn_->setFixedSize(pix_right_.size());
btn_->setMask(pix_right_.mask());
btn_->setStyleSheet("background-image: url(:/images/right.png)");
btn_->setStyleSheet("QPushButton{"
"border-image:url(:/images/right.png)}"
);
