Create tab?

[jpn]

When I click here it will open a new tab like that Firefox press ctr+ T it will open a new tab

You can't create such functionality in Qt Designer which is just a layout designer. You write functionality in code; first you react to the shortcut and then you call QTabWidget::addTab().
