< 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:

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.

Returns the maximum number of items the menu can display.

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.

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.
Reimplemented from cSkinDisplay.
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.

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.

Sets the item at the given Index to Channel.
See SetItem() for more information. If a derived skin class implements this function, it can display a Channel item in a more elaborate way than just a simple line of text. If WithProvider ist true, the provider shall be displayed in addition to the channel's name. If the skin displays the Channel item in its own way, it shall return true. The default implementation does nothing and returns false, which results in a call to SetItem() with a proper text.

Sets the item at the given Index to Event.
See SetItem() for more information. If a derived skin class implements this function, it can display an Event item in a more elaborate way than just a simple line of text. If Channel is not NULL, the channel's name and/or number shall be displayed. If WithDate is true, the date of the Event shall be displayed (in addition to the time). TimerMatch tells how much of this event will be recorded by a timer. If the skin displays the Event item in its own way, it shall return true. The default implementation does nothing and returns false, which results in a call to SetItem() with a proper text.

Sets the item at the given Index to Recording.
See SetItem() for more information. If a derived skin class implements this function, it can display a Recording item in a more elaborate way than just a simple line of text. Level is the currently displayed level of the video directory, where 0 is the top level. A value of -1 means that the full path names of the recordings shall be displayed. If Total is greater than 0, this is a directory with the given total number of entries, and New contains the number of new (unwatched) recordings. If the skin displays the Recording item in its own way, it shall return true. The default implementation does nothing and returns false, which results in a call to SetItem() with a proper text.

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.

Sets the mode by which the items in this menu are sorted.
This is purely informative and may be used by a skin to display the current sort mode by means of some text or symbol.

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.
Reimplemented from cSkinDisplay.
Implemented in cSkinLCARSDisplayMenu, cSkinSTTNGDisplayMenu, cSkinCursesDisplayMenu, and cSkinClassicDisplayMenu.
