close button only for some tabs in Qt

Question

Hello,

I am using Qt for an assignment I have for college, and I want to use QTabWidget to display a chat window much like Pidgin's. I want to make the "group chat" tab always open and impossible to close and the rest of the "private channel" tabs closable.

QTabWidget's setTabsClosable(bool) is not helping ...

any ideas?

I guess you can handle the tabCloseRequest signal and decide whether u'll close a given tab or not

http://doc.qt.nokia.com/4.6/qtabwidget.html#tabCloseRequested

Edit: I created a small example to check it out. My example is a simple QtGui application with a mainwindow that has a tabwidget. I then added the tabCloseRequested slot. Here is the code

void MainWindow::on_tabWidget_tabCloseRequested(int index)
{
   if(someCondition){
       return;
   } else if(anotherCondition){
       ui->tabWidget->removeTab(index);
   }
}

From this example only tabs where the condition doesn't apply will be closed.

You should reimplement your widget's event(Event *e) method, check the type of e, find out CloseEvents, and call parent class's event when you can allow tab to close, or e->ignore() when you do not want it.

Note, then you must parent's event() handle othr events, so do not accept(), reject() or forget them Ж)
