hide tab in Qt
How to hide tab from Qtabwidget in Qt
you can use removeTab() and then addTab() again to show it.
... and you can do your tabs "tabsClosable"
Apart from removing tabs, there currently is no function to hide a tab. A patch against Qt 5 to add this functionality was recently "welcomed":http://lists.qt-project.org/pipermail/development/2012-March/002828.html but it will only appear in Qt 5.1.
Thanks for the reply sir
