Detailed Description

The purpose of modal_dialog_scope is to help to avoid the modal dialog recursion problem. Current toplevel modal dialog handle is stored globally, so when creation of a new modal dialog is blocked, it can be activated to indicate the reason for the task being blocked.

Constructor & Destructor Documentation

modal_dialog_scope::modal_dialog_scope ( HWND  p_wnd ) throw ( )

inline

This constructor initializes the modal dialog scope with specified dialog handle.

: m_initialized(false) {initialize(p_wnd);}

modal_dialog_scope::modal_dialog_scope ( ) throw ( )

inline

This constructor leaves the scope uninitialized (you can call initialize() later with your window handle).

Member Function Documentation

static bool modal_dialog_scope::can_create ( ) throw ( )

inlinestatic

Returns whether creation of a new modal dialog is allowed (false when there's another one active).
NOTE: when calling context is already inside a modal dialog that you own, you should not be checking this before creating a new modal dialog.

void modal_dialog_scope::initialize ( HWND  p_wnd ) throw ( )

Initializes the scope with specified window handle.
