General and Desktop

thanks alot

thank you.

I "think" they are release libs because I configured with release option on. And I'm talking about static lib, 2MB QtCore and 8MB QtGUI seems unbelievable to me... Anyway, what I'm caring about is the size of the final static-linked app.

Yep, that's why I gave the second block of code (which I've just realised had the processEvents() call still in it - it wasn't meant to be there)

Depends on the work done in the callback. Usually the callback function is executed in the library's thread, which may be your main thread. If you need to feed back information into your application, it's probably a good idea to read "Threads, Events & QOjects":https://developer.qt.nokia.com/wiki/Threads_Events_QObjects for more information on how to pass event callbacks into the event loop.

You could use the "text frame feature of a QTextDocument":http://doc.qt.nokia.com/4.7/richtext-cursor.html#frames which can have a border and check, how it looks like in the RTF format.

Ah okay, I see my mistake, @ //Wrong QFuture<void> future = QtConcurrent::run(concurrentFunction(&timer)); //Right QFuture<void> future = QtConcurrent::run(concurrentFunction, &timer); @ Thanks for your help!

And then stuff like this will be possible: @ connect(sender, &Sender::valueChanged, [=](const QString &newValue) { receiver->updateValue("senderValue", newValue); } ); @ Or as is our example @ QObject::connect(play, SIGNAL(clicked()), ={sli->setValue(150);}); @ THIS CODE IS NOT WORKING IN QT4, AND MIGHT NOT EVEN WORK IN QT5 AS THE SYNTAX IS SUBJECT TO CHANGE[/quote] Thanks, really impressive.

[quote author="soroush" date="1313309286"]bq. Changing this must be done in an OS dependant way by overwriting some messages… So, how should I do that?[/quote] As I told you, it's OS dependant. I don't know how to do it on Linux / mac, but on windows, you have to overwrite winEvent and handle WM_NCXXX messages. there are couple of descriptions around on the internet about that, so I suggest you search with google. It's not trivial, and it's on my list to write a wiki for windows on that, but that's currently far away, it's much code you need for that currently...

Thanks , working great

i got it working. i solved it with the first reply advice plus i did not have a click event. thank you for your help.

try @myWin *dialog = new myWin(this); dialog->setAttribute(Qt::WA_DeleteOnClose, true); dialog->show(); @ Edit : Gerolf is faster ;)

That's by design. A Listview is a plain list, not a tree. And a list has noch child elements. It's a table with only one column. If you want to exapnd collaps child elements, you need a treeview.

thanks for the code alexisdm.

also, i am starting to understand what can and can't be done inside of a constructor.

Great you solved it! Could you edit your title and add [solved] in front of it? [done -mariusg]

According to this code, you're not declaring it in the .cpp file either. To declare the variable, you need to add (to your mainwindow.h file) @ protected: loginBox * login; @

Not at all, that was an example. I didn't know how many of those you had so I settled with the easier variant to write down, thinking you would adapt it appropriately (and you did ;) ).

Hmm... why Window Flags Qt example does not have that problem in that case? However not in Mac, need to check other OSs.

Here is the code for the tableView that is in reverse order and not highlighted correctly: dlgprint.cpp @void DlgPrint::createReportTable(QStringList stringList) //strinLlist is used elsewhere { printModel= new QSqlRelationalTableModel (this); printModel-> setEditStrategy(QSqlTableModel::OnManualSubmit); printModel-> setTable (mTableName); //string identified through assessor function printModel-> setRelation (2, QSqlRelation("student", "id", "LName")); printModel-> setRelation (3, QSqlRelation("testNum", "id", "Test")); printModel->setFilter(mFilterString); printModel->select(); proxy = new MyProxyModel(this); proxy->setSourceModel(printModel); ui->printView->setModel(proxy); connect(this,SIGNAL(sendRows(int, int, int, int)), proxy, SLOT(getRows(int, int, int, int))); ui->printView->setItemDelegate(new QSqlRelationalDelegate(this)); ui->printView->setSelectionMode(QAbstractItemView::SingleSelection); ui->printView->setSelectionBehavior(QAbstractItemView::SelectRows); ui->printView->setColumnHidden(0,true);//id ui->printView->resizeColumnsToContents(); printModel->setHeaderData (2, Qt::Horizontal, "Score"); ui->printView->setSortingEnabled(true); ui->printView->resizeColumnsToContents () ; ui->printView->horizontalHeader()->setStretchLastSection(true); highlightCells(); printModel->select(); } void DlgPrint::highlightCells() { float highScore= FLT_MIN; float lowScore= FLT_MAX; float fastReactionTime=FLT_MAX; float slowReactionTime=FLT_MIN; int rowHigh=0; int rowLow=0; int rowFastReact=0; int rowSlowReact=0; float totalTime =0; float totalReactTime=0; float averageScore =0; float averageReact=0; int totalRows = 0; float currentScore; float currentReactTime; QString string; int numRows =proxy->rowCount(); for (int r=0; r<numRows; r++ ) { currentscore = proxy->index(r,2).data(Qt::DisplayRole).toFloat(); currentReactTime = proxy->index(r,3).data(Qt::DisplayRole).toFloat(); //something here to mapToSource?? if (currentScore > highScore) { highScore = currentScore; rowHigh = r; } if (currentScore < lowScore) { lowScore = currentScore; rowLow = r; } totalRows++; totalScore += currentScore; if (currentReactTime < fastReactionTime) { fastReactionTime = currentReactTime; rowFastReact = r; } if (currentReactTime > slowReactionTime) { slowReactionTime = currentReactTime; rowSlowReact = r; } totalReactTime += currentReactTime; } } if (totalRows !=0) { averageScore=totalScore/totalRows; averageReact=totalReactTime/totalRows; } emit sendRows (rowSlow, rowFast,rowSlowReact, rowFastReact); }@ I tried to eliminate the code that was irrelevant to the table creation. Hopefully I didn't forget something. What is wrong here?
