The size hint tells the +menu how much space it needs to reserve for this item, and paint +is called whenever the item needs painting. +<p> This simple mechanism allows you to create all kinds of +application specific menu items. Examples are items showing +different fonts in a word processor or menus that allow the +selection of drawing utilities in a vector drawing program. +<p> A custom item is inserted into a popup menu with +<a href="qmenudata.html#insertItem">TQPopupMenu::insertItem</a>(). +<p> By default, a custom item can also have an icon and a keyboard +accelerator. You can reimplement <a href="#fullSpan">fullSpan</a>() to return TRUE if you +want the item to span the entire popup menu width. This is +particularly useful for labels. +<p> If you want the custom item to be treated just as a separator, +reimplement <a href="#isSeparator">isSeparator</a>() to return TRUE. +<p> Note that you can insert pixmaps or bitmaps as items into a popup +menu without needing to create a TQCustomMenuItem. However, custom +menu items offer more flexibility, and -- especially important +with Windows style -- provide the possibility of drawing the item +with a different color when it is highlighted. +<p> <a href="menu-example.html">menu/menu.cpp</a> shows a simple +example how custom menu items can be used. +<p> Note: the current implementation of TQCustomMenuItem will not +recognize shortcut keys that are from text with ampersands. Normal +accelerators work though. +<p> <img src=qpopmenu-fancy.png> +<p> <p>See also <a href="qmenudata.html">TQMenuData</a>, <a href="qpopupmenu.html">TQPopupMenu</a>, and <a href="misc.html">Miscellaneous Classes</a>. + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="TQCustomMenuItem"></a>TQCustomMenuItem::TQCustomMenuItem () +</h3> +Constructs a TQCustomMenuItem + +<h3 class=fn><a name="~TQCustomMenuItem"></a>TQCustomMenuItem::~TQCustomMenuItem ()<tt> [virtual]</tt> +</h3> +Destroys a TQCustomMenuItem + +<h3 class=fn>bool <a name="fullSpan"></a>TQCustomMenuItem::fullSpan () const<tt> [virtual]</tt> +</h3> +Returns TRUE if this item wants to span the entire popup menu +width; otherwise returns FALSE.
