一 编译结果
二 代码研究
2.1 全部类管理方式
enum class ShowType{
balloon,main};
enum class DictType{
ShanbayDict,YoudaoDict};
namespace DICT{
extern std::unique_ptr<Gui> gui;
extern std::unique_ptr<Application> app;
extern std::unique_ptr<ShanbayDict> shanbayDict;
extern std::unique_ptr<YoudaoDict> youdaoDict;
extern std::unique_ptr<Config> cfg;
extern Dictlogo* logo;
extern ShowType showType;
void init();
void queryWord(const QString& word);
void showWord(DictType dictType,const QString& wordinfo);
}
2.2 浮窗显示管理方式
void Application::run(){
DICT::init();
if(DICT::cfg->isStartloginshanbay()){
DICT::gui->showLoginWin();
}else{
if(!DICT::cfg->isAutohide()){
DICT::gui->showMainWin();
}
}
}
2.3 字典管理方式
QObject::connect(DICT::cfg.get(),&Config::signalChange,
[&](const QString& key, const QVariant& value){
if(key=="screentext"){
getscreenwordAction->setChecked(value.toBool());
}else if(key=="autospeak"){
autospeakAction->setChecked(value.toBool());
setScreenText();
}else if(key=="selectedtext"){
setScreenText();
}else if(key=="clipboardtext"){
setScreenText();
}
});
2.4 qml加载方式
//loginWin
void Gui::showLoginWin(){
qDebug()<<"show loginwin";
if(loginWin==nullptr){
qDebug()<<"load loginwin";
engine->load(QUrl(QStringLiteral("qrc:/qml/Login.qml")));
loginWin = qobject_cast<QWindow*>(engine->rootObjects().last());
loginWin->setIcon(QIcon(":/img/logo.png"));
//loginWin->setFlags(Qt::FramelessWindowHint);
//qDebug()<<engine.rootObjects().size()<<loginWin->objectName();
QObject::connect(loginWin,SIGNAL(signalRegisterClick()),
this,SLOT(registerClick()));
QObject::connect(loginWin, SIGNAL(signalLoginClick(QString,QString,QString)),
this, SIGNAL(signalLoginClick(QString,QString,QString)));
QObject::connect(loginWin,SIGNAL(signalFreshCaptchaImg()),
this,SIGNAL(signalFreshCaptchaImg()));
QObject::connect(this,SIGNAL(signalShowCaptchaImg(QVariant)),
loginWin,SLOT(showCaptchaImg(QVariant)));
QObject::connect(this,SIGNAL(signalSetLoginWinState(QVariant)),
loginWin,SLOT(setState(QVariant)));
}
loginWin->show();
}
2.5 网络通信管理方式
