/**
|
|
* \brief GUI message box for displaying error messages and warnings.
|
|
*
|
|
* PMsgBox is a ROOT-based GUI window that displays multi-line error messages
|
|
* in a scrollable list box. It provides a simple, modal-like interface for
|
|
* showing diagnostic information to the user.
|
|
*
|
|
* The message box:
|
|
* - Parses multi-line error messages (separated by newline characters)
|
|
* - Displays each line in a scrollable list box
|
|
* - Provides an Exit button that terminates the application
|
|
* - Uses ROOT's TGMainFrame for window management
|
|
*
|
|
* Typical use case:
|
|
* \code
|
|
* std::string errorMsg = "Error parsing file:\nLine 42: Invalid syntax\nAborting...";
|
|
* PMsgBox msgBox(errorMsg, gClient->GetRoot(), 640, 240);
|
|
* \endcode
|
|
*
|
|
* \see TGMainFrame for the base class
