- // Implementation Notes:
- // - Each tab points to a LLPanel (see LLTabTuple below)
- // - When a tab is selected, the validation callback
- // (LLUICtrl::mValidateSignal) is called
- // - If the validation callback returns true (or none is provided),
- // the tab is changed and the commit callback
- // (LLUICtrl::mCommitSignal) is called
- // - Callbacks pass the LLTabContainer as the control,
- // and the NAME of the selected PANEL as the LLSD data
