QTabWidget example

stretchthebits

Hello all,
Is there a QTabWidget example? One that programmaticly creates the control and places an edit box, a check box a button or something in some of the tabs?

I am able to create the tab control but I don’t see my edit boxes.

TABCTRLConversion=new QTabWidget(this);
//Position the control
TABCTRLConversion->setGeometry(5, 450, 500, 500);

//We have to create a widget for each tab
WIDGETTemperature=new QWidget(NULL);

tempString="Temperature";
TABCTRLConversion->addTab(WIDGETTemperature, tempString);
WIDGETWeight1=new QWidget(NULL);
tempString="Weight";
TABCTRLConversion->addTab(WIDGETWeight1, tempString);
WIDGETWeight2=new QWidget(NULL);
tempString="Weight2";
TABCTRLConversion->addTab(WIDGETWeight2, tempString);
connect(TABCTRLConversion, SIGNAL(currentChanged(sint)), this, SLOT(OnSelchangeTabConversion(sint)));

xSPosition1=30;
yPosition1=500;
yOffset1=50;
yOffset2=22;
EDITBOXCelsiusSize=71;
STATICTemperature1=new QLabel(WIDGETTemperature);
//Position the control
STATICTemperature1->setGeometry(xSPosition1, yPosition1-yOffset2, 171, 22);
STATICTemperature1->setText(tr("Convert °F to °C and K"));
EDITFahrenheit=new QLineEdit(WIDGETTemperature);
//Position the control
EDITFahrenheit->setGeometry(xSPosition1, yPosition1, EDITBOXCelsiusSize, 22);
EDITFahrenheit->setMaxLength(50);
connect(EDITFahrenheit, SIGNAL(textChanged(QString)), this, SLOT(OnChangeEditFahrenheit(QString)));

I don't know whether your code does not work. One simply creates a QWidget for each "page", and put that into the QTabWidget via addTab(), as you seem to have done.

Then, like any other QWidget, each of those page widgets should have a QLayout, and you add your sub-controls onto the page layouts as usual.

@JonB What if I don't want to use QLayout and I want to position the edit boxes, check boxes, myself.
In fact, when I change tabs, my OnSelchangeTabConversion(sint index) is not getting called.

@stretchthebits said in QTabWidget example:

SIGNAL(currentChanged(sint))

There is no such signal in QTabWidget - this is also printed during runtime on the console.
And please use the new signal/slot syntax - then you can't hit such problems anymore.

Thanks, I changed that part to
connect(TABCTRLConversion, &QTabWidget::currentChanged, this, &CChemicalADlg::OnSelchangeTabConversion);

and it worked. One problem solved. One more to go.

@stretchthebits Then please mark the topic as solved, thx.
