just use the filePath without further modification, its already the complete path.
This code

QDir d = QFileInfo(filePath).absoluteDir(); QString absolute=d.absolutePath();

will lead you to the dir above the selected path...

@SGaist Dman that was silly mistake :(

@SGaist Thanx mate

What you need in fact is a QFormLayout (a subset of the grid layout) where you can insert the pairs of widgets with QFormLayout::addRow.

@Lasith You should open the database only once. Currently you do it each time button is pressed.

Hi,

There's no need for any global objects all the more if you only have one active connection for your application but it's also valid if you are managing multiple connections. The QSqlDatabase class already provides everything you need.

Like written in the documentation, if you are only using one connection, don't give it a name, it will become the default connection and all the SQL related classes will use it by default.

If you have several connections, it's easy to retrieve the one you are interested in by using QSqlDatabase::database.

On a side note, you should properly test the outcome of your open call. Right now it could be failing and you don't care about that possibility.

@Lasith
Hi
old type c array can also work.
Its just a matter of what is registered already.
You can register your own types.

Hi
Yes calling the function directly is actually a better solution in this case.
Its worth mentioning that the so called slots are 100% normal c++ member functions
and can be called without any Qt involvement/use of.

void MainWindow::on_pushButton_clicked() { int value=ui->lineEdit->text().toInt(); // get value Dialog dialog1; dialog1.sendIntData(value); dialog1.exec(); }

@mostefa said in connecting to database when a form loads using signals and slots:

I think that this post is duplicate

Strictly speaking it isn't, although it's quite similar.

@mostefa Thanx mate

Hi,

Your code won't work, your QSqlDatabase object is invalid.

Please take the time to look at the code example in QSqlDatabase's documentation as well as the example provided.

It' also discouraged to store database object like that locally. QSqlDatabase allows for easy connection handling without the need for these local copies.

http://download.qt.io/official_releases/qt/

You also have the MaintenanceTool that offers that possibility.

@Kushan
basically Oracle supports requests via ODBC driver. So this is more a matter of your DB configuration.

@J.Hilk Thanx alot

While I'm here, you can use https://github.com/VSRonin/Qt-Model-Serialisation/tree/dev

CsvModelSerialiser modelSaver; modelSaver->setModel(ui->tableWidget_2->model()); modelSaver->setCsvSeparator(" "); QFile mFile("C:/Users/Desktop/Qt/textfiles/test.txt"); modelSaver->saveModel(&mFile);

@Rohith
Hi
Im not sure what goes wrong.
I guess you are still not using the RIGHT click layout menu ?
Do not drag layouts from left box.

Please see this video.

You're welcome !

Since you have it working now, please mark that thread as solved using the "Topic Tools" button so that other forum users may know a solution has been found :)

@chaithubk Just create a directory containing QtCreator, all needed libraries and plug-ins and copy it to other machines. You can zip the folder to reduce its size. You can take a look at this: http://doc.qt.io/qt-5/linux-deployment.html As QtCreator uses Qt the description there applies to it as well.

I was also thinking, after my last post, that this is more a possible improvement suggestion. Thanks for that pointer.

@koahnig said in Qt Creator 4.3.0 & stability:

Not sure if it can be consiedered as a bug.

Bug, a suggestion or a task, call it however suits you; it should still allow you to uninstall the tool.

This prevents a deselect during installation and also prevents the removal and reinstallation.

I don't know that part of the infrastructure well, so I'll take your word for it. I rarely use the maintenance tool, but many people do, so it'd be good to work as smoothly as possible. ;)

@Sumit Should be possible, but I never used Bitbake

@rhonaldjr

u have marked as solved.
cheers.

Thanks,

CMake insists on creating the build directory, and it is annoying that you have to delete build directories all over the place when all you want to do is take a quick look at some sources. So creator "builds" in a temporary directory to extract information from CMake -- till you actually trigger an explicit build from creator. At that point the actual build directory is created and all the files go there.

You need to tell cmake to run your command in the source directory if those commands depend on being run from there: CMake usually does not build in the directory your sources are and will default to running stuff in the build directory.

Hi and welcome to devnet,

Did you install Visual Studio 2015 ? If so did you install the C++ component ?

If you have the .pdb you can add it to Creator. I don't have windows on hand, but it was somewhere in the Tools > Options ... > Debugger > CDB configuration.

@maydin As libs are not located in include directories it should be:

LIBS += -L/usr/lib -lncurses

@mrjj , Thanks bud. It worked. You have just made my life easier.

Thank you! I didnt noticed that. I did correct this mistakes, but still getting the same error:( and empty window :/
