Show and hide Tab page

[fulin]

Hi,

I know that we can hide a page of a Tab by

int page_index = 0;
ui->myTab->removeTab(page_index);

int page_index = 0;
ui->myTab->removeTab(page_index);

To copy to clipboard, switch view to plain text mode 

but how can I show this page again. There seems no such kind of function in Qt 4.7 Tab

int page_index = 0;
ui->myTab->showPage(page_index);

int page_index = 0;
ui->myTab->showPage(page_index);

To copy to clipboard, switch view to plain text mode 

Thank you in advance
