Access to UI elements

[ivanotero76]

Hi everyone!

I am attemptting to access to elements of mainwindow.ui (it would be named ui elements? ).

I have two sample of use of this elements.

First work fine but in case of comboBox It doen't work.

Could you help me?

QString def_fileGbxml = ui->lineEditFile->text();
 
    QComboBox cb_tipoEdificio = this->ui->comboBox_1

QString def_fileGbxml = ui->lineEditFile->text();

    QComboBox cb_tipoEdificio = this->ui->comboBox_1

To copy to clipboard, switch view to plain text mode 

How can define it to use in my mainwindow.cpp. I want to load it from file of data.

I have data on file like that:

constructionIdRefs:
cons-1
cons-2
cons-3
cons-4
cons-5
cons-6
***************
openingTypes:
FixedWindow
NonSlidingDoor
end1;
end2;

constructionIdRefs:
cons-1
cons-2
cons-3
cons-4
cons-5
cons-6
***************
openingTypes:
FixedWindow
NonSlidingDoor
end1;
end2;

To copy to clipboard, switch view to plain text mode 

I can write file like I want. Do you recommend another organization of data??

On the other hand. I read about define manual ComboBox and Label but in this way I can't view it in main window.

For example:

QGridLayout *layoutPrincipal = new QGridLayout();
    layoutPrincipal->addWidget(new QLabel("Latitud"),0,0);
    latitud = new QLineEdit();
    layoutPrincipal->addWidget(latitud,0,1);
    layoutPrincipal->addWidget(new QLabel("Longitud"),1,0);
    longitud = new QLineEdit();
    layoutPrincipal->addWidget(longitud,1,1);
 
    getLocation = new QPushButton("Get Position");
    layoutPrincipal->addWidget(getLocation,3,0,1,2);
 
    valores_combo << "primero" << "segundo" << "tercero";
    combo_buildings = new QComboBox();
 
    combo_buildings->addItems(valores_combo);
 
    this->setWindowTitle("Config of initial values of gbxml");
    this->setLayout(layoutPrincipal);

QGridLayout *layoutPrincipal = new QGridLayout();
    layoutPrincipal->addWidget(new QLabel("Latitud"),0,0);
    latitud = new QLineEdit();
    layoutPrincipal->addWidget(latitud,0,1);
    layoutPrincipal->addWidget(new QLabel("Longitud"),1,0);
    longitud = new QLineEdit();
    layoutPrincipal->addWidget(longitud,1,1);

    getLocation = new QPushButton("Get Position");
    layoutPrincipal->addWidget(getLocation,3,0,1,2);

    valores_combo << "primero" << "segundo" << "tercero";
    combo_buildings = new QComboBox();

    combo_buildings->addItems(valores_combo);

    this->setWindowTitle("Config of initial values of gbxml");
    this->setLayout(layoutPrincipal);

Is there any way to view this elements in mainwindow.ui?

It is possible a mix of both?

Yo need to use a pointer:

QComboBox *cb_tipoEdificio = this->ui->comboBox_1

QComboBox *cb_tipoEdificio = this->ui->comboBox_1

The rest of your post is just very hard to understand.
