QT中的QPropertyAnimation使用和toast案列

最近使用学习到动画这一块,无意中接触到使用QPropertyAnimation来完成 类似 toast效果的东西

主要功能:
1、toast实现位置可以根据父窗口而改变;
2、显示时间默认是一分钟,可调
1、QPropertyAnimation自带效果
QPropertyAnimation是Qt自带的动画类,该类可以实现简单的控件动画效果,比如对控件的移动、缩放、不透明度这些来做动画效果(使用某效果之前需要使用setPropertyName函数指定需要的动画属性名,以下三个是Qt已经定义好的)。
1、移动(pos):主要实现移动效果,如从某个点移动到另一个点,所使用的变量类型为QPoint等。
2、缩放(geometry):可实现缩放和移动效果,该属性可以实现指定控件的缩放,并且在缩放的基础上还能实现移动。
3、不透明度(windowOpacity):实现控件的透明度设置(不过该属性只能对顶级窗口使用,对普通控件这些无效)。
2、QPropertyAnimation自定义效果
见引用。
3、QPropertyAnimation toast实现
1.toast头文件
代码如下(示例):
#ifndef TOAST_H
#define TOAST_H
#include <QtWidgets/QWidget>
#include <QLabel>
class Toast : public QWidget
{
Q_OBJECT
public:
Toast(QWidget *parent = Q_NULLPTR);
~Toast();
void setText(const QString& text);
void showAnimation(int timeout = 500);
void movetoPosition(int x,int y);
static void showTip(const QString& text,int x,int y,QWidget* parent = nullptr);
private:
QLabel *label = nullptr;
QWidget *widget = nullptr;
};
#endif // TOAST_H
2.toast cpp
代码如下(示例):
#include "toast.h"
#include <QPropertyAnimation>
#include <QScreen>
#include <QGuiApplication>
#include <QPainter>
#include <QTimer>
#include <QDebug>
#include <QGridLayout>
Toast::Toast(QWidget *parent)
: QWidget(parent)
{
label = new QLabel();
label->setStyleSheet("background-color: rgba(0,0,0,0.80);\nborder-radius: 26px;\ncolor: #FFFFFF;\nfont-family: microsoft yahei;\nfont-size: 16px;\npadding-left:25px;\npadding-right:25px;");
QGridLayout *layout = new QGridLayout;
layout->addWidget(label);
widget = new QWidget();
widget->setWindowFlags(windowFlags() | Qt::FramelessWindowHint | Qt::Tool);
widget->setAttribute(Qt::WA_TranslucentBackground, true);
widget->setGeometry(0,0,170,52);
widget->setLayout(layout);
QScreen* pScreen = QGuiApplication::primaryScreen();
widget->move((pScreen->size().width() - widget->width()) / 2, pScreen->size().height() /2);
widget->setVisible(true);
}
Toast::~Toast()
{
delete label;
delete widget;
}
void Toast::setText(const QString& text)
{
label->setText(text);
}
void Toast::showAnimation(int timeout)
{
QTimer::singleShot(timeout, [&]
{
QPropertyAnimation *animation = new QPropertyAnimation(this, "windowOpacity");
animation->setDuration(500);
animation->setStartValue(1);
animation->setEndValue(0);
animation->start();
connect(animation, &QPropertyAnimation::finished, [&]
{
close();
deleteLater();
});
});
}
void Toast::movetoPosition(int x,int y)
{
widget->move(x,y);
}
void Toast::showTip(const QString& text ,int x,int y,QWidget* parent /*= nullptr*/)
{
Toast* toast = new Toast(parent);
toast->setWindowFlags(toast->windowFlags() | Qt::WindowStaysOnTopHint);
toast->setText(text);
toast->adjustSize();
toast->movetoPosition(x, y);
toast->showAnimation();
}
3.main cpp
void MainWindow::on_pushButton_4_clicked()
{
Toast::showTip("测试成功!测试成功!测试成功!测试成功!测试成功!",this->x(),this->y());
}
void MainWindow::on_pushButton_5_clicked()
{
qDebug()<<"12";
// Toast::showTip(QApplication::translate("Dialog", "Please set destination IP !"));
Toast::showTip("测试成功!",this->x(),this->y());
qDebug()<<"123";
}void MainWindow::on_pushButton_4_clicked()
{
Toast::showTip("测试成功!测试成功!测试成功!测试成功!测试成功!",this->x(),this->y());
}
4、总结
文章参考引用的内容,然后自己实现一个toast,只需要包含头文件和cpp就可以在程序中使用了
