 - lookup xw-view for xwidget in emacs window(during redisplay)
 (- do something for all siblings of a xw-view. not atm)
 
+*** TODO xwidget creation interface
+xwidgets are a little bit like emacs processes but also a little bit
+like emacs images. Therefore its not perfectly obvious how to handle
+creation. Currently I just use hardcoded identifiers. the real scheme
+needs to be something else.
+
+Heres a tentative approach:
+- xwidget-create returns a xwidget object, like process creation
+  functions. the xwidget will be largely uninitialized until
+  discovered by redisplay. an xw belongs to a buffer
+- xwidget-insert inserts the xwidget in a buffer. when discovered by
+  redisplay it will be initialized and a xwidget-view allocated
+- an event will be emitted when initialization is finished when
+  relevant like for sockets
+
+the problem with this aproach is that its not really legal to reuse
+xwidget objects by writing several display specs who reference the
+same xwidget. It could presumably be done but it would just become
+weird for no real benefit. the big preblem is that the display spec
+decides the on-screen size, and its not sane to have xwidget views
+with different sizes. therefore such display specs would need to be
+catched and dissallowed. Except it is hard because AFAIK the specs
+don't have an identity as such. A flag in the structure could be set
+by lookup so the first display attempt would win. but then you can't
+rewrite the spec to change the size. hmmm. A third approach would be
+to just allow the 1st spec refering an xw during a redisplay to take
+effect, the rest are signaled as errors. this wouldnt be too bad.
+
+the other aproach would be to work more like images:
+
+- write the display spec with all information needed to create the
+  xwidget.
+- retrieve the xwidget objet from the spec with an xwidget-at-point function. It
+  can be uninitalized which client code must handle. Unlike
+  assynchronous process creation we dont get back a handle, because
+  there is none yet.
+- emitted event on initialization, when needed. Many widgets don't
+  need this. for instance, a button sends an event when pressed. but
+  you can't press it unless its on screen, and then its initialized
+  properly. 
+
+This approach seemed good, but how do I know which instance
+generates an event if I cant set the id beforehand?
+
+so, therefore, the first two aproach is used.
