Pls tell me how can I hide the tabpanel "..." title if there is only one tab in my tab?
I can’t use Ext.Panel because I use rather complicated methods to generate extjs code on the server, and there are a lot of design errors that prevent me from generating a regular Ext.Panel for this case.

tnx all, Solution: I am adding css rules
.strip-hidden .x-tab-strip-wrap
{
display: none;
}
.strip-show .x-tab-strip-wrap
{
display: block;
}
and server side (delphi, something like ExtPascal)
if (frmContainer.Tab.Items.Count = 1) then
frmContainer.Tab.Cls := 'strip-hidden'
else
frmContainer.Tab.Cls := 'strip-show';
So it works for me (chrome, firefox).
I add 2 rules because I have windows in the windows, so if the child windows have many tabs, they will be hidden using the css rule of the parent window. so i have 2 rules and it works.
