149 Q. WHY does Dialogs::Dialogs pass `this' to dialog constructors?
151 A. To avoid a segfault.
152 The dialog constructors need to connect to their
153 respective showSomeDialog signal(*) but in order to do
154 that they need to get the address of the Dialogs instance
155 from LyXView::getDialogs(). However, since the Dialogs
156 instance is still being constructed at that time
157 LyXView::getDialogs() will *not* return the correct
158 address because it hasn't finished being constructed.
159 A Catch-22 situation (or is that the chicken and the egg...).
160 So to get around the problem we pass the address of
161 the newly created Dialogs instance using `this'.
163 (*) -- I'm using signals exclusively to guarantee that the gui code
164 remains hidden from the rest of the system. In fact the only
165 header related to dialogs that anything in the non-gui-specific
166 code gets to see is Dialogs.h! Even Dialogs.h doesn't know what a
167 FormCopyright class looks like or that its even going to be used!
169 No other gui dialog headers are seen outside of the gui-specific
170 directories! This ensures that the gui is completely separate from
171 the rest of LyX. All this through the use of a few simple signals.
172 BUT, the price is that during construction we need to connect the
173 implementations show() method to the showSomeDialog signal and this
174 requires that we have an instance of Dialogs and the problem mentioned
177 Almost all other dialogs should be able to operate using the same style
178 of signalling used for Copyright. Exceptions should be handled
179 by adding a specific show or update signal. For example, spellchecker
180 needs to set the next suspect word and its options/replacements so we
182 Signal0<void> updateSpellChecker;
184 Since we would have to have a
185 Signal0<void> showSpellChecker;
187 in order to just see the spellchecker and let the user push the [Start]
188 button then the updateSpellChecker signal will make the SpellChecker
189 dialog get the new word and replacements list from LyX. If you really,
190 really wanted to you could define a signal that would pass the new
191 word and replacements:
192 Signal2<void, string, vector<string> > updateSpellChecker;
194 (or something similar) but, why bother when the spellchecker can get
195 it anyway with a LyXFunc call or two. Besides if someone extends
196 what a dialog does then they also have to change code in the rest of
197 LyX to pass more parameters or get the extra info via a function
198 call anyway. Thus reducing the independence of the two code bases.
200 We don't need a separate update signal for each dialog because most of
201 them will be changed only when the buffer is changed (either by closing
202 the current open buffer or switching to another buffer in the current
203 LyXView -- different BufferView same LyXView or same BufferView same
206 So we minimise signals but maximise independence and programming
207 simplicity, understandability and maintainability. It's also
208 extremely easy to add support for Qt or gtk-- because they use
209 signals already. Guis that use callbacks, like xforms, must have their
210 code wrapped up like that in the form_copyright.[Ch] which is awkward
211 but will at least allow multiple instances of the same dialog.
213 Signals will also be a great help in controlling the splashscreen --
214 once signalled to hide it can disconnect from the signal and remove
217 LyXFuncs will be used for requesting/setting LyX internal info. This
218 will ensure that scripts or LyXServer-connected applications can all
219 have access to the same calls as the internal user-interface.
