Detailed Description

TMenuBar objects represent the horizontal menu bars from which menu selections can be made by:

1. direct clicking
2. F10 selection and hot keys
3. selection (highlighting) and pressing Enter
4. hot keys

The main menu selections are displayed in the top menu bar. This is represented by an object of type TMenuBar, usually owned by your TApplication object.

Submenus are displayed in objects of type TMenuBox. Both TMenuBar and TMenuBox are derived from TMenuView (which is in turn derived from TView).

For most TVision applications, you will not be involved directly with menu objects. By overriding TApplication::initMenuBar() with a suitable set of nested new TMenuItem and new TMenu calls, TVision takes care of all the standard menu mechanisms.

Member Function Documentation

TStreamable * TMenuBar::build ( ) [static]

Called to create an object in certain stream-reading situations. Reimplemented from TMenuView.

void TMenuBar::draw ( ) [virtual]

Draws the menu bar with the default palette. The TMenuItem::name and TMenuItem::disabled data members of each TMenuItem object in the menu linked list are read to give the menu legends in the correct colors. The current (selected) item is highlighted. Reimplemented from TView.

TRect TMenuBar::getItemRect ( TMenuItem * item ) [virtual]

Returns the rectangle occupied by the given menu item. It can be used with mouseInView() to determine if a mouse click has occurred on a given menu selection. Reimplemented from TMenuView.
