QTabWidgets: I can't remove a tab

[prasad_N]

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

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

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

To copy to clipboard, switch view to plain text mode 

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:

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

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

To copy to clipboard, switch view to plain text mode
