42    + code to read this & generate UIs is in:
43	+ DTD: xmlscript/dtd/dialog.dtd
44	+ xmlscript/source/xmldlg_imexp/imp_share.hxx, line 674
45	+ xmlscript/source/misc/unoservices.cxx
46		xmlscript/source/xmlflat_imexp/xmlbas_import.cxx (?)
47		"com.sun.star.comp.xmlscript.XMLBasicImporter"
48	+ the dialog piece seems separate ?
49		"importDialogModel" ...
50	+ cf. the interesting test code ...
51	+ cd xmlscript/test
52	  dmake
53	  ../unxlngi6.pro/bin/imexp /opt/OOInstall ./test.xml
54	    + generates & renders a dialog ...
55
56	+ This code has ~all we need to get a simple impl.
57	    + compatibility wrappers [!]

59    // first create model:
60    Reference< container::XNameContainer > xModel( xContext->getServiceManager()->createInstanceWithContext(

81** Basic dialog editor:
82
83    + basctl/source/dlged/dlged.cxx
84	+ dialog editor (?)
85    + basctl/source/basicide/basobj3.cxx
86    + basctl/source/basicide/basides3.cxx
87	+ BasicIDEShell:CreateDlgWin ...
88
89
90** FIXME:
91	+ createPeer - when called is always passed
92	  the toplevel [ it seems ... ]
93	+ we need to pass a container instead ...
94		+ or have some separate hint / method ?
95		+ or call the 'setChild' inside the model
96		  construction bits ? [!?]
97
98UnoControlContainer::addingControl:
99	+ only caller to 'setContext'
100		+ sets the 'Parent' for peers ...
101
102Dialog is an UnoControlContainer ...
103	+ hmm ...
104	+ 'XControlContainer'
105		+ perhaps just what we need ... [!]
106	+ our VBox should be one ...
107
108	+ Other things: tab widgets are 'UnoControlContainers' ...
109		+ finally remembered: xml foo ...
110		+
111
112
113	+ FIXME: it -seems- that we don't store
114		 much hierarchy in the model [ any ? ]
115		+ UnoControlModel -> ?
116
117	+ UnoControlDialogModel - has an XNameContainer ...
118		+ but ... only the UnoControl-Dialog-Model has this ...
119
120
121	+ Wow - even the percieved hierarchy:
122		+ 'exportDialogModel'
123			+ achieved by 'getElementNames'
124				-> flat set of names ... [urgh]
125
126	+ So - we need to add more structure:
127		+ XNameContainers ...
128			+ that we insert into [!?]
129		+ we also need to retain order for packing.
130
131	+ need a list of sillies to reverse / revert (?) ...
132
133	+ back-compat:
134		+ kill bogus nesting eg. radiogroup ...
135			[ have a group/tag instead - or hierarchical names ? ]
136		+ ditto for 'titledbox' ...
137		+ menulists - seem rather unrelated / bogus anyway.
138		+ Add into toplevel & child ...
139
140    + copy Dialog bits into unocontrolcontainer.cxx ...
141	+ re-using unocontrolcontainer ...
142
143
144** FIXME:
145    + we need property introspection on the awt widgets:
146	+ but they have no property interfaces [!] -
147	    interestingly the UnoControl's don't either
148	    only the UnoControlModel foo ...
149	+ unocontrols.cxx:
150	    Uno
151    + source/helper/property.cxx
152	+ has all the type information ...
153	+ but no information on what properties are
154	  valid for a type ... - implicit in the UnoControlModel's
155	  code ...
156	    + ImplGetPropertyInfos ...
157
158    + add to vclxwindow.cxx:
159	+ inc/toolkit/helper/property.hxx
160	+ 'getProperties' static ...
161
162** It seems that things like UnoControlComboBoxModel are missing
163   some derived properties: EchoChar (etc.)
164    UnoControlDateFieldModel - missing ... EchoChar too (?) - deliberate ?
165    + query these ... [!?]
166
167layout container - start child 'combobox'
168   missing property 46 (EchoChar)
169   missing property 48 (HardLineBreaks)
170   missing property 12 (HScroll)
171   missing property 104 (LineEndFormat)
172   missing property 10 (MultiLine)
173   missing property 13 (VScroll)
174
175    + add regression test:
176	+ count number of properties ...
177
178
179TODO:
180	add 'XPropertySetInfo' to VCLXWindow:
181	    + trivial to implement :-)
182	    + hook it to Ricardo's parser ... [!] :-)
183
184* xmlscript
185	+ xmldlg_import.cxx -
186	+ xml_helper/xml_impctx.cxx - foo ...
187
188
189* plan:
190	+ hard-code container hooks into the xmlscript/ parser ...
191	+ create a layout object in toolkit/
192		+ populate it with good things ...
193
194	+ coupling to toolkit - widget instantiation: how ...
195		+ ComponentInfos
196			+ vclxtoolkit.cxx:
197		+ has a 'hook function' for 'fnSvtCreateWindow'
198		  for SVT widgets :-) [ grotesque ;-]
199			+ [ wow - fetched by dlopen! ;-]
200
201	+ A little app - a-la solver: using awt (?)
202		+ XMessageBoxFactory ...
203		+ XToolkit:
204			+ CreateWindow ...
205		+ ** how does the xml code generate these guys ? **
206
207	+ what APIs does the xmlimporter use ? not 'createWindow' seemingly.
208
209+ existing xml import uses: property bag a -lot-:
210	Reference< beans::XPropertySet > xProps(
211	        _pImport->_xDialogModel, UNO_QUERY_THROW );
212	* we do _xDialogModel->insertByName (new any<XControlModel>())
213		+ to build hierarchy ( cf. ~ControlImportContext )
214
215	DialogImport:
216		css::uno::Reference< css::container::XNameContainer > _xDialogModel;
217
218	Reference< container::XNameContainer > xModel( xContext->getServiceManager()->createInstanceWithContext(
219			OUString( RTL_CONSTASCII_USTRINGPARAM( "com.sun.star.awt.UnoControlDialogModel" ) ), xContext ), UNO_QUERY );
220
221	toolkit/source/controls/dialogcontrol.cxx
222		+ UnoControlButtonModel (eg.)
223		+ service 'UnoControlModel' ...
224
225	+ poke at 'titledbox' or 'radiogroup' to see how containment works there ...
226		+ how will child widget properties work ?
227		+ bug with a 'vbox' inside a 'titledbox' ...
228	+ titledbox - acts as a container (interesting)
229		- offsetting child positions
230	+ how will pseudo-containers eg. "radiogroup" cope ?
231
232	+ propose new syntax: [ with child properties a-la glade ]:
233
234	<hbox id="baa" flange="true">
235		<child padding="0" expand="false" fill="false">
236			<radio id="foo" value="..."/>
237		</child>
238		<radio id="foo" value="..."/>
239	</hbox>
240
241	+ if 'child' element omitted - default properties used ...
242	+ if multiple elements in same 'child' set: all have the same props.
