< This class implements the general purpose menu display, which is used throughout the program to display information and let the user interact with items.
A menu consists of the following fields, each of which is explicitly set by calls to the member functions below:

Clears the entire central area of the menu.
Implemented in cSkinLCARSDisplayMenu, cSkinSTTNGDisplayMenu, cSkinCursesDisplayMenu, and cSkinClassicDisplayMenu.

Returns the part of the given string that follows the given Tab (where 0 indicates the beginning of the string).
If no such part can be found, NULL will be returned.

|
virtual |
Returns a pointer to the font which is used to display text with SetText().
The parameter FixedFont has the same meaning as in SetText(). The default implementation returns NULL. Therefore a caller of this method must be prepared to receive NULL if the plugin doesn't implement this method. The returned pointer is valid a long as the instance of cSkinDisplayMenu exists.
Reimplemented in cSkinLCARSDisplayMenu, cSkinSTTNGDisplayMenu, cSkinCursesDisplayMenu, and cSkinClassicDisplayMenu.
|
virtual |
Returns the width in pixel of the area which is used to display text with SetText().
The width of the area is the width of the central area minus the width of any possibly displayed scroll-bar or other decoration. The default implementation returns 0. Therefore a caller of this method must be prepared to receive 0 if the plugin doesn't implement this method.
Reimplemented in cSkinLCARSDisplayMenu, cSkinSTTNGDisplayMenu, and cSkinClassicDisplayMenu.

pure virtual |
Returns the maximum number of items the menu can display.
Implemented in cSkinLCARSDisplayMenu, cSkinSTTNGDisplayMenu, cSkinCursesDisplayMenu, and cSkinClassicDisplayMenu.

|
virtual |
If this menu contains a text area that can be scrolled, this function will be called to actually scroll the text.
Up indicates whether the text shall be scrolled up or down, and Page is true if it shall be scrolled by a full page, rather than a single line. An object of the cTextScroller class can be used to implement the scrolling text area.

pure virtual |
Sets the color buttons to the given strings.
If any of the values is NULL, any previous text must be removed from the related button.
Implemented in cSkinLCARSDisplayMenu, cSkinSTTNGDisplayMenu, cSkinCursesDisplayMenu, and cSkinClassicDisplayMenu.

|
pure virtual |
Sets the Event that shall be displayed, using the entire central area of the menu.
The Event's 'description' shall be displayed using a cTextScroller, and the Scroll() function will be called to drive scrolling that text if necessary.
Implemented in cSkinLCARSDisplayMenu, cSkinSTTNGDisplayMenu, cSkinCursesDisplayMenu, and cSkinClassicDisplayMenu.
Referenced by cMenuEvent::Display().
|
pure virtual |
Sets the item at the given Index to Text.
Index is between 0 and the value returned by MaxItems(), minus one. Text may contain tab characters ('\t'), which shall be used to separate the text into several columns, according to the values set by a prior call to SetTabs(). If Current is true, this item shall be drawn in a way indicating to the user that it is the currently selected one. Selectable can be used to display items differently that can't be selected by the user. Whenever the current status is moved from one item to another, this function will be first called for the old current item with Current set to false, and then for the new current item with Current set to true.
Implemented in cSkinLCARSDisplayMenu, cSkinSTTNGDisplayMenu, cSkinCursesDisplayMenu, and cSkinClassicDisplayMenu.

virtual |
Sets the current menu category.
This allows skins to handle known types of menus in different ways, for instance by displaying icons or special decorations. A derived class can reimplement this function to be informed of any changes in the menu category. If it does, it shall call the base class function in order to set the members accordingly for later calls to the MenuCategory() function.
Reimplemented in cSkinLCARSDisplayMenu.

pure virtual |
Sets a one line message Text, with the given Type.
Type can be used to determine, e.g., the colors for displaying the Text. If Text is NULL, any previously displayed message must be removed, and any previous contents overwritten by the message must be restored.
Implemented in cSkinLCARSDisplayMenu, cSkinSTTNGDisplayMenu, cSkinCursesDisplayMenu, and cSkinClassicDisplayMenu.

Sets the Recording that shall be displayed, using the entire central area of the menu.
The Recording's 'description' shall be displayed using a cTextScroller, and the Scroll() function will be called to drive scrolling that text if necessary.
Implemented in cSkinLCARSDisplayMenu, cSkinSTTNGDisplayMenu, cSkinCursesDisplayMenu, and cSkinClassicDisplayMenu.

|
virtual |
Sets the Total number of items in the currently displayed list, and the Offset of the first item that is currently displayed (the skin knows how many items it can display at once, see MaxItems()).
This can be used to display a scrollbar.
