/**
* @defgroup Entry Entry
*
* An entry is a convenience widget which shows
* a box that the user can enter text into. Unlike a
* @ref Scrolled_Entry widget, entries DO NOT scroll with user
* input. Entry widgets are capable of expanding past the
* boundaries of the window, thus resizing the window to its
* own length.
*
* You can also insert "items" in the entry with:
*
* \<item size=16x16 vsize=full href=emoticon/haha\>\</item\>
*
* for example. sizing can be set bu size=WxH, relsize=WxH or absize=WxH with
* vsize=ascent or vsize=full. the href=NAME sets the item name. Entry
* supports a list of emoticon names by default. These are:
*
* - emoticon/angry
* - emoticon/angry-shout
* - emoticon/crazy-laugh
* - emoticon/evil-laugh
* - emoticon/evil
* - emoticon/goggle-smile
* - emoticon/grumpy
* - emoticon/grumpy-smile
* - emoticon/guilty
* - emoticon/guilty-smile
* - emoticon/haha
* - emoticon/half-smile
* - emoticon/happy-panting
* - emoticon/happy
* - emoticon/indifferent
* - emoticon/kiss
* - emoticon/knowing-grin
* - emoticon/laugh
* - emoticon/little-bit-sorry
* - emoticon/love-lots
* - emoticon/love
* - emoticon/minimal-smile
* - emoticon/not-happy
* - emoticon/not-impressed
* - emoticon/omg
* - emoticon/opensmile
* - emoticon/smile
* - emoticon/sorry
* - emoticon/squint-laugh
* - emoticon/surprised
* - emoticon/suspicious
* - emoticon/tongue-dangling
* - emoticon/tongue-poke
* - emoticon/uh
* - emoticon/unhappy
* - emoticon/very-sorry
* - emoticon/what
* - emoticon/wink
* - emoticon/worried
* - emoticon/wtf
*
* These are built-in currently, but you can add your own item provieer that
* can create inlined objects in the text and fill the space allocated to the
* item with a custom object of your own.
*
* See the entry test for some more examples of use of this.
*
* Signals that you can add callbacks for are:
* - "changed" - The text within the entry was changed
* - "activated" - The entry has had editing finished and changes are to be committed (generally when enter key is pressed)
* - "press" - The entry has been clicked
* - "longpressed" - The entry has been clicked for a couple seconds
* - "clicked" - The entry has been clicked
* - "clicked,double" - The entry has been double clicked
* - "focused" - The entry has received focus
* - "unfocused" - The entry has lost focus
* - "selection,paste" - A paste action has occurred
* - "selection,copy" - A copy action has occurred
* - "selection,cut" - A cut action has occurred
* - "selection,start" - A selection has begun
* - "selection,changed" - The selection has changed
* - "selection,cleared" - The selection has been cleared
* - "cursor,changed" - The cursor has changed
* - "anchor,clicked" - The anchor has been clicked
