• Connecting an overloaded PyQT signal using new-style syntax

  - by Claudio

  I am designing a custom widget which is basically a QGroupBox holding a configurable number of QCheckBox buttons, where each one of them should control a particular bit in a bitmask represented by a QBitArray. In order to do that, I added the QCheckBox instances to a QButtonGroup, with each button given an integer ID: def populate(self, num_bits, parent = None): """ Adds check boxes to the GroupBox according to the bitmask size """ self.bitArray.resize(num_bits) layout = QHBoxLayout() for i in range(num_bits): cb = QCheckBox() cb.setText(QString.number(i)) self.buttonGroup.addButton(cb, i) layout.addWidget(cb) self.setLayout(layout) Then, each time a user would click on a checkbox contained in self.buttonGroup, I'd like self.bitArray to be notified so I can set/unset the corresponding bit in the array. For that I intended to connect QButtonGroup's buttonClicked(int) signal to QBitArray's toggleBit(int) method and, to be as pythonic as possible, I wanted to use new-style signals syntax, so I tried this: self.buttonGroup.buttonClicked.connect(self.bitArray.toggleBit) The problem is that buttonClicked is an overloaded signal, so there is also the buttonClicked(QAbstractButton*) signature. In fact, when the program is executing I get this error when I click a check box: The debugged program raised the exception unhandled TypeError "QBitArray.toggleBit(int): argument 1 has unexpected type 'QCheckBox'" which clearly shows the toggleBit method received the buttonClicked(QAbstractButton*) signal instead of the buttonClicked(int) one. So, the question is, how can we specify, using new-style syntax, that self.buttonGroup emits the buttonClicked(int) signal instead of the default overload - buttonClicked(QAbstractButton*)?

• problem with QPropertyAnimation in Qt

  - by belhaouary

  Hi , i have a problem with QPropertyAnimation in Qt my code: QString my_text = "Hello Animation"; ui->textBrowser->setText((quote_text)); ui->textBrowser->show(); QPropertyAnimation animation2(ui->textBrowser,"geometry"); animation2.setDuration(1000); animation2.setStartValue(QRect(10,220/4,1,1)); animation2.setEndValue(QRect(10,220,201,71)); animation2.setEasingCurve(QEasingCurve::OutBounce); animation2.start(); till now it seems very good , but the problem is that i can see this animation only when i show a message box after it . QMessageBox m; m.setGeometry(QRect(100,180,100,50)); m.setText("close quote"); m.show(); m.exec(); when i remove the code of this message box , i can't see the animation anymore. the functionality of the program doesn't require showing this MessageBox at all. Can anybody help?

• Segmentation fault in Qt application framework

  - by yan bellavance

  this generates a segmentation fault becuase of "QColor colorMap[9]";. If I remove colorMap the segmentation fault goes away. If I put it back. It comes back. If I do a clean all then build all, it goes away. If I increase its arraysize it comes back. On the other hand if I reduce it it doesnt come back. I tired adding this array to another project and What could be happening. I am really curious to know. I have removed everything else in that class. This widget subclassed is used to promote a widget in a QMainWindow. class LevelIndicator : public QWidget { public: LevelIndicator(QWidget * parent); void paintEvent(QPaintEvent * event ); float percent; QColor colorMap[9]; int NUM_GRADS; }; the error happens inside ui_mainwindow.h at one of these lines: hpaFwdPwrLvl->setObjectName(QString::fromUtf8("hpaFwdPwrLvl")); verticalLayout->addWidget(hpaFwdPwrLvl); I know i am not providing much but I will give alink to the app. Im trying to see if anyone has a quick answer for this.

• QObject::connect not connecting signal to slot

  - by user1662800

  I am using C++ and Qt in my project and my problem is QObject::connect function doesn't connect signal to a slot. I have the following classes: class AddCommentDialog : public QDialog { Q_OBJECT public: ...some functions signals: void snippetAdded(); private slots: void on_buttonEkle_clicked(); private: Ui::AddCommentDialog *ui; QString snippet; }; A part of my Main window: class MainWindow : public QMainWindow { Q_OBJECT public: explicit MainWindow(QWidget *parent = 0); ~MainWindow(); private slots: void commentAddedSlot(); void variableAddedSlot(); ... private: AddCommentDialog *addCommentDialog; ... }; Ant the last dialog; class AddDegiskenDialog : public QDialog { Q_OBJECT public: ... signals: void variableAdded(); private slots: void on_buttonEkle_clicked(); private: Ui::AddDegiskenDialog *ui; ... }; In the main window constructor i connect signals and slots: addCommentDialog=new AddCommentDialog(); addDegiskenDialog=new AddDegiskenDialog(); connect(addDegiskenDialog, SIGNAL(variableAdded()), this, SLOT(variableAddedSlot())); connect(addCommentDialog, SIGNAL(snippetAdded()), this, SLOT(commentAddedSlot())); The point is my commentAddedSlot is connected to it's signal successfully, but commentAddedSlot is failed. There is the Q_OBJECT macros, no warning such as about no x slot. In addition to this, receivers(SIGNAL(snippetAdded())) gives me 1 but receivers(SIGNAL(variableAdded())) gives me 0 and i used commands qmake -project; qmake and make to fully compile. What am i missing?

• How to access widgets created within functions in later function calls in Qt

  - by Inanepenguin

  So currently I have code, in C++, that creates a few QLabels, a QLineEdit, and a QCheckBox when a selection is made from a QComboBox. However, I would like to be able to access the widgets I have created in a later function to destroy them if a new selection is made from the combo box. I am able to access the objects created from using the Designer by doing ui-Object but i am not able to do that with objects created by using my own code. Can I do that some how, because I know how to work with that. In short, I would like to be able to dynamically create/destroy QWidgets based on selections made by the user. Is there a reference I should know of to do this, or any documentation? Or am I just completely going about this the wrong way? Here is the code I presently have for creating the objects: if (eventType == QString::fromStdString("Birthday")) { QLabel *label1 = new QLabel ("Celebrant: "); QLabel *label2 = new QLabel ("Surprise: "); QLineEdit *lineEdit = new QLineEdit; QCheckBox *box = new QCheckBox; ui->gridLayout->addWidget(label1,3,0,1,1, 0); ui->gridLayout->addWidget(label2,4,0,1,1,0); ui->gridLayout->addWidget(lineEdit,3,1,1,1,0); ui->gridLayout->addWidget(box,4,1,1,2,0); }

• how can i make sure to get the server response correctly when i invoke the server with QNetworkReque

  - by noname

  I wrote the server site call in Qt, but i haven't get the server response for every server invoking. I have to use the server reply to continue the program flow. The request is correctly reached to server and server do reply.The server is also on my machine. Here is the code how i make the server site call; QNetworkAccessManager nam1 = new QNetworkAccessManager(this); qnetmg=nam1; QObject::connect(nam1, SIGNAL(finished(QNetworkReply*)),this,SLOT(finishedGettingMarker(QNetworkReply*))); QString strurl="http://localhost:8080/ServerWeb"; QUrl url(strurl); QNetworkRequest preq(url); QNetworkReply* reply = nam1->get(preq); qreply=reply; Inside finisedGettingMarker slot, i have already eliminate for QNetworkReply-error case and i used one global variable for QNetworkAccessManager;"qnetmg" and one global variable for QNetworkReply;"qreply". And also i make qnetmg.disconnect(this,0); and qreply.abort(); inside that slot method. But the problem is i haven't got the response for every server invoking time. If anyone who know the way to solve it , please reply me. This situation happened only in Opera. Thanks in advance.

• How can I use Qt to get html code of this NCBI page??

  - by user308503

  I'm trying to use Qt to download the html code from the following url: http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=nucleotide&cmd=search&term=AB100362 this url will re-direct to www.ncbi.nlm.nih.gov/nuccore/27884304 I try to do it by following way, but I cannot get anything. it works for some webpage such as www.google.com, but not for this NCBI page. is there any way to get this page?? QNetworkReply::NetworkError downloadURL(const QUrl &url, QByteArray &data) { QNetworkAccessManager manager; QNetworkRequest request(url); QNetworkReply *reply = manager.get(request); QEventLoop loop; QObject::connect(reply, SIGNAL(finished()), &loop, SLOT(quit())); loop.exec(); if (reply->error() != QNetworkReply::NoError) { return reply->error(); } data = reply->readAll(); delete reply; return QNetworkReply::NoError; } void GetGi() { int pos; QString sGetFromURL = "http://www.ncbi.nlm.nih.gov/entrez/query.fcgi"; QUrl url(sGetFromURL); url.addQueryItem("db", "nucleotide"); url.addQueryItem("cmd", "search"); url.addQueryItem("term", "AB100362"); QByteArray InfoNCBI; int errorCode = downloadURL(url, InfoNCBI); if (errorCode != 0 ) { QMessageBox::about(0,tr("Internet Error "), tr("Internet Error %1: Failed to connect to NCBI.\t\nPlease check your internect connection.").arg(errorCode)); return "ERROR"; } }

• can I access a struct inside of a struct without using the dot operator?

  - by yan bellavance

  I have 2 structures that have 90% of their fields the same. I want to group those fields in a structure but I do not want to use the dot operator to access them. The reason is I already coded with the first structure and have just created the second one. before: struct{ int a; int b; int c; object1 name; } str1; struct{ int a; int b; int c; object2 name; } str2; now I would create a third struct: struct{ int a; int b; int c; } str3; and would change the str1 and atr2 to this: struct{ str3 str; object1 name; } str1; struct { str3 str; object2 name; } str2; Finally I would like to be able to access a,b and c by doing: str1 myStruct; myStruct.a; myStruct.b; myStruct.c; and not: myStruct.str.a; myStruct.str.b; myStruct.str.c; Is there a way to do such a thing. The reason for doing this is I want keep the integrety of the data if chnges to the struct were to occur and to not repeat myself and not have to change my existing code and not have fields nested too deeply. RESOLVED: thx for all your answers. The final way of doing it so that I could use auto-completion also was the following: struct str11 { int a; int b; int c; }; typedef struct str22 : public str11 { QString name; }hi;

• Qt - problem appending to QList of QList

  - by bullettime

  I'm trying to append items to a QList at runtime, but I'm running on a error message. Basically what I'm trying to do is to make a QList of QLists and add a few customClass objects to each of the inner lists. Here's my code: widget.h: class Widget : public QWidget { Q_OBJECT public: Widget(QWidget *parent = 0); ~Widget(); public slots: static QList<QList<customClass> > testlist(){ QList<QList<customClass> > mylist; for(int w=0 ; w<5 ; w++){ mylist.append(QList<customClass>()); } for(int z=0 ; z<mylist.size() ; z++){ for(int x=0 ; x<10 ; x++){ customClass co = customClass(); mylist.at(z).append(co); } } return mylist; } }; customclass.h: class customClass { public: customClass(){ this->varInt = 1; this->varQString = "hello world"; } int varInt; QString varQString; }; main.cpp: int main(int argc, char *argv[]) { QApplication a(argc, argv); Widget w; QList<QList<customClass> > list; list = w.testlist(); w.show(); return a.exec(); } But when I try to run the application, it gives off this error: error: passing `const QList<customClass>' as `this' argument of `void List<T>::append(const T&) [with T = customClass]' discards qualifiers I also tried inserting the objects using foreach: foreach(QList<customClass> list, mylist){ for(int x=0 ; x<10 ; x++){ list.append(customClass()); } } The error was gone, but the customClass objects weren't appended, I could verify that by using a debugging loop in main that showed the inner QLists sizes as zero. What am I doing wrong?

• Container item implementation

  - by onurozcelik

  Hi, I am working in Train Traffic Controller software project. My responsibility in this project is to develop the visual railroad GUI. We are implementing the project with Qt. By now I am using QGraphicsLinearLayout to hold my items. I am using the layout because I do not want to calculate coordinates of each item. So far I wrote item classes to add the layout. For instance SwitchItem class symbolizes railroad switch in real world. Each item class is responsible for its own painting and events. So far so good. Now I need a composite item that can contain two or more item. This class is going to be responsible for painting the items contained in it. I need this class because I have to put two or more items inside same layout cell. If I don' t put them in same cell I can' t use layout. See the image below. BlockSegmentItem and SignalItem inside same cell. Here is my compositeitem implementation. #include "compositeitem.h" CompositeItem::CompositeItem(QString id,QList<FieldItem *> _children) { children = _children; } CompositeItem::~CompositeItem() { } QRectF CompositeItem::boundingRect() const { FieldItem *child; QRectF rect(0,0,0,0); foreach(child,children) { rect = rect.united(child->boundingRect()); } return rect; } void CompositeItem::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget ) { FieldItem *child; foreach(child,children) { child->paint(painter,option,widget); } } QSizeF CompositeItem::sizeHint(Qt::SizeHint which, const QSizeF &constraint) const { QSizeF itsSize(0,0); FieldItem *child; foreach(child,children) { // if its size empty set first child size to itsSize if(itsSize.isEmpty()) itsSize = child->sizeHint(Qt::PreferredSize); else { QSizeF childSize = child->sizeHint(Qt::PreferredSize); if(itsSize.width() < childSize.width()) itsSize.setWidth(childSize.width()); itsSize.setHeight(itsSize.height() + childSize.height()); } } return itsSize; } void CompositeItem::contextMenuEvent(QGraphicsSceneContextMenuEvent *event) { qDebug()<<"Test"; } This code works good with painting but when it comes to item events it is problematic. QGraphicsScene treats the composite item like a single item which is right for layout but not for events. Because each item has its own event implementation.(e.g. SignalItem has its special context menu event.) I have to handle item events seperately. Also I need a composite item implementation for the layout. How can I overcome this dilemma?

• Qt, can't display child widget

  - by Blin

  I have two widgets defined as follows class mainWindow : public QWidget { Q_OBJECT public: mainWindow(); void readConfig(); private: SWindow *config; QVector <QString> filePath; QVector <QLabel*> alias,procStatus; QVector <int> delay; QGridLayout *mainLayout; QVector<QPushButton*> stopButton,restartButton; QVector<QProcess*> proc; QSignalMapper *stateSignalMapper, *stopSignalMapper, *restartSignalMapper; public slots: void openSettings(); void startRunning(); void statusChange(int); void stopProc(int); void restartProc(int); void renew(); }; class SWindow : public QWidget { Q_OBJECT public: SWindow(QWidget *parent=0); void readConfig(); void addLine(int); private: QVector<QPushButton*> selectButton; QVector<QLabel*> filePath; QVector<QLineEdit*> alias; QSignalMapper *selectSignalMapper; QVector<QSpinBox*> delay; QGridLayout *mainLayout; public slots: void selectFile(int); void saveFile(); void addLineSlot(); }; when i create and display SWindow object from mainWindow like this void mainWindow::openSettings() { config = new SWindow(); config->show(); } everything is ok, but now i need to access the mainWindow from SWindow, and void mainWindow::openSettings() { config = new SWindow(this); config->show(); } doesn't display SWindow. How can i display SWindow? How do i call a function on widget close?

• Using images in QListWidget, is this possible?

  - by Neko

  Hi, again. :) As with the last few times I posted here, I have a question about QT, which I am using to create a chat messenger client. To display the list of online users, I'm using a QListWidget, as created like this: listWidget = new QListWidget(horizontalLayoutWidget); listWidget->setObjectName("userList"); QSizePolicy sizePolicy1(QSizePolicy::Preferred, QSizePolicy::Expanding); sizePolicy1.setHorizontalStretch(0); sizePolicy1.setVerticalStretch(0); sizePolicy1.setHeightForWidth(listWidget->sizePolicy().hasHeightForWidth()); listWidget->setSizePolicy(sizePolicy1); listWidget->setMinimumSize(QSize(30, 0)); listWidget->setMaximumSize(QSize(150, 16777215)); listWidget->setBaseSize(QSize(100, 0)); listWidget->setContextMenuPolicy(Qt::CustomContextMenu); Users are shown by constantly refreshing the list, like this: (Note: There are different channels, with different userlists, so refreshing it is the most efficient thing to do, as far as I know.) void FMessenger::refreshUserlist() { if (currentPanel == 0) return; listWidget = this->findChild<QListWidget *>(QString("userList")); listWidget->clear(); QList<FCharacter*> charList = currentPanel->charList(); QListWidgetItem* charitem = 0; FCharacter* character; foreach(character, charList) { charitem = new QListWidgetItem(character->name()); // charitem->setIcon(QIcon(":/Images/status.png")); listWidget->addItem(charitem); } } This has always worked perfectly. The line that I commented out is the one I have problems with: my current goal is to be able to display a user's online status with an image, which represents whether they are busy, away, available, etc. Using setIcon() does absolutely nothing though, apparently; the items still show up as they used to, without icons. I'm aware that this is probably not the way this function needs to be used, but I have found little documentation about it online, and absolutely no useful examples of implementations. My question is, can anybody help me with fixing this problem? Any help would be appreciated terrifically, like always!

• Getting the responseText from XMLHttpRequest-Object

  - by Sammy46

  I wrote a cgi-script with c++ to return the query-string back to the requesting ajax object. I also write the query-string in a file in order to see if the cgi script works correctly. But when I ask in the html document for the response Text to be shown in a messagebox i get a blank message. here is my code: js: <script type = "text/javascript"> var XMLHttp; if(navigator.appName == "Microsoft Internet Explorer") { XMLHttp = new ActiveXObject("Microsoft.XMLHTTP"); } else { XMLHttp = new XMLHttpRequest(); } function getresponse () { XMLHttp.open ("GET", "http://localhost/cgi-bin/AJAXTest?" + "fname=" + document.getElementById('fname').value + "&sname=" + document.getElementById('sname').value,true); XMLHttp.send(null); } XMLHttp.onreadystatechange=function(){ if(XMLHttp.readyState == 4) { document.getElementById('response_area').innerHTML += XMLHttp.readyState; var x= XMLHttp.responseText alert(x) } } </script> First Names(s)<input onkeydown = "javascript: getresponse ()" id="fname" name="name"> <br> Surname<input onkeydown = "javascript: getresponse();" id="sname"> <div id = "response_area"> </div> C++: int main() { QFile log("log.txt"); if(!log.open(QIODevice::WriteOnly | QIODevice::Text)) { return 1; } QTextStream outLog(&log); QString QUERY_STRING= getenv("QUERY_STRING"); //if(QUERY_STRING!=NULL) //{ cout<<"Content-type: text/plain\n\n" <<"The Query String is: " << QUERY_STRING.toStdString()<< "\n"; outLog<<"Content-type: text/plain\n\n" <<"The Query String is: " <<QUERY_STRING<<endl; //} return 0; } I'm happy about every advice what to do! EDIT: the output to my logfile works just fine: Content-type: text/plain The Query String is: fname=hello&sname=world I just noticed that if i open it with IE8 i get the query-string. But only on the first "keydown" after that IE does nothing.

• Qt 4.6 Adding objects and sub-objects to QWebView window object (C++ & Javascript)

  - by Cor

  I am working with Qt's QWebView, and have been finding lots of great uses for adding to the webkit window object. One thing I would like to do is nested objects... for instance: in Javascript I can... var api = new Object; api.os = new Object; api.os.foo = function(){} api.window = new Object(); api.window.bar = function(){} obviously in most cases this would be done through a more OO js-framework. This results in a tidy structure of: >>>api ------------------------------------------------------- - api Object {os=Object, more... } - os Object {} foo function() - win Object {} bar function() ------------------------------------------------------- Right now I'm able to extend the window object with all of the qtC++ methods and signals I need, but they all have 'seem' to have to be in a root child of "window". This is forcing me to write a js wrapper object to get the hierarchy that I want in the DOM. >>>api ------------------------------------------------------- - api Object {os=function, more... } - os_foo function() - win_bar function() ------------------------------------------------------- This is a pretty simplified example... I want objects for parameters, etc... Does anyone know of a way to pass an child object with the object that extends the WebFrame's window object? Here's some example code of how I'm adding the object: mainwindow.h #ifndef MAINWINDOW_H #define MAINWINDOW_H #include <QtGui/QMainWindow> #include <QWebFrame> #include "mainwindow.h" #include "happyapi.h" class QWebView; class QWebFrame; QT_BEGIN_NAMESPACE class MainWindow : public QMainWindow { Q_OBJECT public: MainWindow(QWidget *parent = 0); private slots: void attachWindowObject(); void bluesBros(); private: QWebView *view; HappyApi *api; QWebFrame *frame; }; #endif // MAINWINDOW_H mainwindow.cpp #include <QDebug> #include <QtGui> #include <QWebView> #include <QWebPage> #include "mainwindow.h" #include "happyapi.h" MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) { view = new QWebView(this); view->load(QUrl("file:///Q:/example.htm")); api = new HappyApi(this); QWebPage *page = view->page(); frame = page->mainFrame(); attachWindowObject(); connect(frame, SIGNAL(javaScriptWindowObjectCleared()), this, SLOT(attachWindowObject())); connect(api, SIGNAL(win_bar()), this, SLOT(bluesBros())); setCentralWidget(view); }; void MainWindow::attachWindowObject() { frame->addToJavaScriptWindowObject(QString("api"), api); }; void MainWindow::bluesBros() { qDebug() << "foo and bar are getting the band back together!"; }; happyapi.h #ifndef HAPPYAPI_H #define HAPPYAPI_H #include <QObject> class HappyApi : public QObject { Q_OBJECT public: HappyApi(QObject *parent); public slots: void os_foo(); signals: void win_bar(); }; #endif // HAPPYAPI_H happyapi.cpp #include <QDebug> #include "happyapi.h" HappyApi::HappyApi(QObject *parent) : QObject(parent) { }; void HappyApi::os_foo() { qDebug() << "foo called, it want's it's bar back"; }; I'm reasonably new to C++ programming (coming from a web and python background). Hopefully this example will serve to not only help other new users, but be something interesting for a more experienced c++ programmer to elaborate on. Thanks for any assistance that can be provided. :)

• Qt - reloading widget contents

  - by bullettime

  I'm trying to modify the fridge magnets example by adding a button that will reload the widget where the draggable labels are drawn, reflecting any changes made to the text file it reads. I defined another class that would contain the button and the DragWidget object, so there would be an instance of this class instead of DragWidget in main(): class wrapWidget: public QWidget { public: wrapWidget(); }; wrapWidget::wrapWidget() { QGridLayout *gridlayout = new QGridLayout(); DragWidget *w = new DragWidget(); QPushButton *b = new QPushButton("refresh"); gridlayout ->addWidget(w,0,0); gridlayout ->addWidget(b,1,0); setLayout(gridlayout ); connect(b,SIGNAL(clicked()),w,SLOT(draw())); } The call to connect is where I'm trying to do the refresh thing. In the original fridge magnets example, all the label drawing code was inside the constructor of the DragWidget class. I moved that code to a public method that I named 'draw()', and called this method from the constructor instead. Here's DragWidget definition and implementation: #include <QWidget> QT_BEGIN_NAMESPACE class QDragEnterEvent; class QDropEvent; QT_END_NAMESPACE class DragWidget : public QWidget { public: DragWidget(QWidget *parent = 0); public slots: void draw(); protected: void dragEnterEvent(QDragEnterEvent *event); void dragMoveEvent(QDragMoveEvent *event); void dropEvent(QDropEvent *event); void mousePressEvent(QMouseEvent *event); void paintEvent(QPaintEvent *event); }; DragWidget::DragWidget(QWidget *parent) : QWidget(parent) { draw(); QPalette newPalette = palette(); newPalette.setColor(QPalette::Window, Qt::white); setPalette(newPalette); setMinimumSize(400, 100);//qMax(200, y)); setWindowTitle(tr("Fridge Magnets")); setAcceptDrops(true); } void DragWidget::draw(){ QFile dictionaryFile(":/dictionary/words.txt"); dictionaryFile.open(QFile::ReadOnly); QTextStream inputStream(&dictionaryFile); int x = 5; int y = 5; while (!inputStream.atEnd()) { QString word; inputStream >> word; if (!word.isEmpty()) { DragLabel *wordLabel = new DragLabel(word, this); wordLabel->move(x, y); wordLabel->show(); wordLabel->setAttribute(Qt::WA_DeleteOnClose); x += wordLabel->width() + 2; if (x >= 245) { x = 5; y += wordLabel->height() + 2; } } } } I thought that maybe calling draw() as a slot would be enough to reload the labels, but it didn't work. Putting the draw() call inside the widget's overriden paintEvent() instead of the constructor didn't work out as well, the program would end up in an infinite loop. What I did was obviously not the right way of doing it, so what should I be doing instead?

• Super Noob C++ variable help

  - by julian

  Ok, I must preface this by stating that I know so so little about c++ and am hoping someone can just help me out... I have the below code: string GoogleMapControl::CreatePolyLine(RideItem *ride) { std::vector<RideFilePoint> intervalPoints; ostringstream oss; int cp; int intervalTime = 30; // 30 seconds int zone =ride->zoneRange(); if(zone >= 0) { cp = 300; // default cp to 300 watts } else { cp = ride->zones->getCP(zone); } foreach(RideFilePoint* rfp, ride->ride()->dataPoints()) { intervalPoints.push_back(*rfp); if((intervalPoints.back().secs - intervalPoints.front().secs) > intervalTime) { // find the avg power and color code it and create a polyline... AvgPower avgPower = for_each(intervalPoints.begin(), intervalPoints.end(), AvgPower()); // find the color QColor color = GetColor(cp,avgPower); // create the polyline CreateSubPolyLine(intervalPoints,oss,color); intervalPoints.clear(); intervalPoints.push_back(*rfp); } } return oss.str(); } void GoogleMapControl::CreateSubPolyLine(const std::vector<RideFilePoint> &points, std::ostringstream &oss, QColor color) { oss.precision(6); QString colorstr = color.name(); oss.setf(ios::fixed,ios::floatfield); oss << "var polyline = new GPolyline(["; BOOST_FOREACH(RideFilePoint rfp, points) { if (ceil(rfp.lat) != 180 && ceil(rfp.lon) != 180) { oss << "new GLatLng(" << rfp.lat << "," << rfp.lon << ")," << endl; } } oss << "],\"" << colorstr.toStdString() << "\",4);"; oss << "GEvent.addListener(polyline, 'mouseover', function() {" << endl << "var tooltip_text = 'Avg watts:" << avgPower <<" <br> Avg Speed: <br> Color: "<< colorstr.toStdString() <<"';" << endl << "var ss={'weight':8};" << endl << "this.setStrokeStyle(ss);" << endl << "this.overlay = new MapTooltip(this,tooltip_text);" << endl << "map.addOverlay(this.overlay);" << endl << "});" << endl << "GEvent.addListener(polyline, 'mouseout', function() {" << endl << "map.removeOverlay(this.overlay);" << endl << "var ss={'weight':5};" << endl << "this.setStrokeStyle(ss);" << endl << "});" << endl; oss << "map.addOverlay (polyline);" << endl; } And I'm trying to get the avgPower from this part: AvgPower avgPower = for_each(intervalPoints.begin(), intervalPoints.end(), AvgPower()); the first part to cary over to the second part: << "var tooltip_text = 'Avg watts:" << avgPower <<" <br> Avg Speed: <br> Color: "<< colorstr.toStdString() <<"';" << endl But of course I haven't the slightest clue how to do it... anyone feeling generous today? Thanks in advance

• Qt : crash due to delete (trying to handle exceptions...)

  - by Seub

  I am writing a program with Qt, and I would like it to show a dialog box with a Exit | Restart choice whenever an error is thrown somewhere in the code. What I did causes a crash and I really can't figure out why it happens, I was hoping you could help me understanding what's going on. Here's my main.cpp: #include "my_application.hpp" int main(int argc, char *argv[]) { std::cout << std::endl; My_Application app(argc, argv); return app.exec(); } And here's my_application:hpp: #ifndef MY_APPLICATION_HPP #define MY_APPLICATION_HPP #include <QApplication> class Window; class My_Application : public QApplication { public: My_Application(int& argc, char ** argv); virtual ~My_Application(); virtual bool notify(QObject * receiver, QEvent * event); private: Window *window_; void exit(); void restart(); }; #endif // MY_APPLICATION_HPP Finally, here's my_application.cpp: #include "my_application.hpp" #include "window.hpp" #include <QMessageBox> My_Application::My_Application(int& argc, char ** argv) : QApplication(argc, argv) { window_ = new Window; window_->setAttribute(Qt::WA_DeleteOnClose, false); window_->show(); } My_Application::~My_Application() { delete window_; } bool My_Application::notify(QObject * receiver, QEvent * event) { try { return QApplication::notify(receiver, event); } catch(QString error_message) { window_->setEnabled(false); QMessageBox message_box; message_box.setWindowTitle("Error"); message_box.setIcon(QMessageBox::Critical); message_box.setText("The program caught an unexpected error:"); message_box.setInformativeText("What do you want to do? <br>"); QPushButton *restart_button = message_box.addButton(tr("Restart"), QMessageBox::RejectRole); QPushButton *exit_button = message_box.addButton(tr("Exit"), QMessageBox::RejectRole); message_box.setDefaultButton(restart_button); message_box.exec(); if ((QPushButton *) message_box.clickedButton() == exit_button) { exit(); } else if ((QPushButton *) message_box.clickedButton() == restart_button) { restart(); } } return false; } void My_Application::exit() { window_->close(); //delete window_; return; } void My_Application::restart() { window_->close(); //delete window_; window_ = new Window; window_->show(); return; } Note that the line window_->setAttribute(Qt::WA_DeleteOnClose, false); means that window_ (my main window) won't be deleted when it is closed. The code I've written above works, but as far as I understand, there's a memory leak: I should uncomment the line //delete window_; in My_Application::exit() and My_Application::restart(). But when I do that, the program crashes when I click restart (or exit but who cares). (I'm not sure this is useful, in fact it might be misleading, but here's what my debugger tells me: a segmentation fault occurs in QWidgetPrivate::PaintOnScreen() const which is called by a function called by a function... called by My_Application::notify()) When I do some std::couts, I notice that the program runs through the entire restart() function and in fact through the entire notify() function before it crashes. I have no idea why it crashes. Thanks in advance for your insights! Update: I've noticed that My_Application::notify() is called very often. For example, it is called a bunch of times while the error dialog box is open, also during the execution of the restart function. The crash actually occurs in the subfunction QApplication::notify(receiver, event). This is not too surprising in light of the previous remark (the receiver has probably been deleted) But even if I forbid the function My_Application::notify() to do anything while restart() is executed, it still crashes (after having called My_Application::notify() a bunch of times, like 15 times, isn't that weird)? How should I proceed? Maybe I should say (to make the question slightly more relevant) that my class My_Application also has a "restore" function, which I've not copied here to try to keep things short. If I just had that restart feature I wouldn't bother too much, but I do want to have that restore feature. I should also say that if I keep the code with the "delete window_" commented, the problem is not only a memory leak, it still crashes sometimes apparently. There must surely be a way to fix this! But I'm clueless, I'd really appreciate some help! Thanks in advance.

  - by Whospal

  I created a python test program (Test_InfoPanel.py) that has MainWindow with dockWidget, and within it, a tabWidget with scrollArea widget. However, when I resize the MainWindow, the vertical scrollbar doesn't auto-appear when the Similarly, when I undock the dockWidget & resize, the vertical scrollbar doesn't auto-appear. Pls help!

initially created the mainWindow as a Dialog, but realized that after undock & redock, the dockWidget doesn't dock properly. Somehow there's an offset. This doesn't seem to be a problem if the mainWindow is a QtGui.QMainWindow instead of a QtGui.QDialog.
