Error C2352: illegal call of non-static member function

b1gsnak3

you are trying to update a window for a non-existent object... You must first create an object of NewSurveyDialog type class and then call the method for that object...

the error says it all:
you're trying to access the member function which isn't declared as static.
Since you are using a member inside the function you need to call the method on an instance instead of the static way (with prepended NewSurveyDialog::).

Thanks for the replies.

I do create an object. I only put in some of the code.

When I declare in newsurveydialog.h as a static

static void parseNewSurveyData( QString str );

I get the following compile errors.

newsurveydialog.cpp
.\newsurveydialog.cpp(85) : error C2227: left of '->IDC_EDIT_OUTPUT_RAW' must point to class/struct/union/generic type

as i wrote in my post: you are accessing a member (ui) inside this function. Thus you can't make it static.
Because you can only access other static members out of a static method.

Here is the code that creates the ui-> object for ui->IDC_EDIT_OUTPUT_RAW->append( str );

NewSurveyDialog::NewSurveyDialog(QWidget *parent ) :
QDialog(parent),
ui(new Ui::NewSurveyDialog)
{
ui->setupUi(this);

// set flags default values
m_bNotifyPaused = FALSE;
//nConnection = NULL;

//connect(ui->buttonOK, SIGNAL(clicked()), SLOT(buttonPressedOK()));

connect(ui->IDC_BUTTON_BROWSE_SAVE_SURVEY, SIGNAL(clicked()), SLOT(buttonPressedBrowseSaveSurvey()));

connect(ui->StartNewSurvey, SIGNAL(clicked()), SLOT(buttonStartNewSurvey()));

connect(ui->PauseAnalysis, SIGNAL(clicked()), SLOT(buttonPauseAnalysis()));


//ui->IDC_RSSI_BARGRAPH->setVisible(false);

initProgress(-115,-55);

updateProgress( -115 );

ui->IDC_RSSI_BARGRAPH->setVisible(true);

ui->IDC_EDIT_OUTPUT_RAW->setVisible(true);

ui->IDC_REPEATER_ID->insert( gRptrSerialNbr);

ui->IDC_PARENT_ID->insert( gMasterID );

nonJoinableCount = 0;

}

rraf02

so how do I pass a data string to newSurveyDialog ?

raven-worx

did you read my first post at all? You should use a instance to your object where you want to call the method.
Or you could use SIGNALS/SLOTS to send a string to another object.

That's the code creating an ui-object...
but the method you're calling isn't a member of the ui-class but of your class NewSurveyDialog
-> that's the one you have to instantiate and call the method on its instance

b1gsnak3

in pannel connection.cpp you must create an instance of NewSurveyDialog... For example:

@
mData = thread->getData().replace(request.trimmed(), tr(”“)).trimmed();
qDebug() << “trimmed ==” << mData;

mData = thread->getData();
qDebug() << “trimmed ==” << mData;
NewSurveyDialog *someName = new NewSurveyDialog(); // This is an instance of a object
somename->parseNewSurveyData(mData); // This is how you call the method for that object
@

I'm new at QT and figuring it out as I go, (Reading up and then Trial and Terror).

As my brother said when he was posted to Scotland, I know you are speaking english, but I don't understand a word you are saying. :-)

I thought I already had an instance already created as I am updating the new window, I just need to pass data to it from the com port data stream.

So do you have an example of how I might use SIGNALS/SLOTS to send a string from another object.
I will also try to read up on signals/slots.

BTW, thanks for the help.

Mario84

even if you really had created the instance... "NewSurveyDialog::parseNewSurveyData( mData );" is always a static member call

rraf02

Thanks. I will give that a try.
