QTabWidgets: I can't remove a tab

Hello,
Sorry for my English. I'm new to Qt, in my project the user can move from one tab to the next one. ( Slot of the button: ui->Pestanas->insertTab(1, ui->Pestana_Orden_Trabajo, "Orden de Trabajo");
ui->Pestanas->setCurrentIndex(1); )

It works, but I would like to just show the first tab when the window appears for the first time.
I've tried this:

Code:

---

Partes::Partes(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::Partes)
{
    ui->setupUi(this);
 
    ui->Pestanas->setCurrentIndex(0);
    ui->Pestanas->removeTab(1);
    ui->Pestanas->removeTab(2);
 
}

---

It makes disappear the second tab that comes with the QTabWidget deffault form when you first include it in the ui. But the the tab that I added for designing the widgets I want it to bring inside doesn't disappear.

Does anyone know any way to do it?

Thanks for replying!

lets say you have 3 tabs, index 0, 1, 2

Code:

---

ui->Pestanas->setCurrentIndex(0);
ui->Pestanas->removeTab(1);
ui->Pestanas->removeTab(2);

---

You set current tab to first tab. //index 0
And you removed 2nd tab with //ui->Pestanas->removeTab(1); //index 1
Now tab indexes will changed, now tab indexes you have are : 0, 1

And now you are trying to remove 3rd Tab(index 2) which is not there //ui->Pestanas->removeTab(2);


Try this:

Code:

---

ui->Pestanas->removeTab(1);
ui->Pestanas->removeTab(1);

---

Your solution solved my problem!
Very well explained.

Thank you very much!
