QCAD配置文件

实际上是使用了QSettings，可以存储一系列设置。每个设置包括指定设置名称（键）的一个字符串和一个与该键关联的·QVariant存储数据。使用setValue()可以实现一个设置。

配置多线程

[GraphicsView] 
Multithreading=true 
Threads=10

// enable multithreaded graphics view:
if (RSettings.getBoolValue("GraphicsView/Multithreading", true)) {
    var numThreads = RSettings.getIntValue("GraphicsView/Threads", Math.max(RS.getIdealThreadCount(), 6));
    if (numThreads!==1) {
        this.graphicsView.setNumThreads(numThreads);
        //EAction.handleUserMessage(qsTr("Threads:") + " " + numThreads);
    }
  }

 int slice = int(floor(double(list.length())/painterThread.length()));
QList<QFuture<void> > futureThread;
for (int threadId=0; threadId<painterThread.length(); threadId++) {
    int start = threadId*slice;
    int end = (threadId+1)*slice;
    if (threadId==painterThread.length()-1) {
        end = list.length();
    }
    //qDebug() << "slice:" << start << end;
    futureThread.append(QtConcurrent::run(this, &RGraphicsViewImage::paintEntitiesThread, threadId, list, start, end));
}
//RDebug::stopTimer(100, "launch threads");

//RDebug::startTimer(100);
for (int i=0; i<futureThread.length(); i++) {
    futureThread[i].waitForFinished();
}


void RGraphicsViewImage::paintEntitiesThread(int threadId, QList<REntity::Id>& list, int start, int end) {
    for (int i=start; i<end; i++) {
        paintEntityThread(threadId, list[i]);
    }
}

配置文字渲染

[TextRendering] 
RenderAs=Paths

bool RSettings::isTextRenderedAsText() {
    if (textRenderedAsText==-1) {
        textRenderedAsText = getStringValue("TextRendering/RenderAs", "Text") == "Text";
    }
    return textRenderedAsText;
}


void RTextBasedEntity::exportEntity(RExporter& e, bool preview, bool forceSelected) const {
    Q_UNUSED(preview)

    // TODO: use transforms:
    RTextBasedData data = getData();

    if (e.isTextRenderedAsText()) {
        // export text as text and return part that cannot be rendered as text as paths:
        QList<RPainterPath> paths = e.exportText(data, forceSelected);
        // export part of text that can only be rendered as painter paths (CAD fonts):
        e.exportPainterPaths(paths, getPosition().z);
    }
    else {
        e.exportPainterPathSource(data, getPosition().z);
    }
}
