events |
141 |
" |
|
142 |
All events are processed in a workstations dispatchEvent method. |
|
143 |
There, incoming events are first sent to itself, for a first (view independent) |
|
144 |
preprocessing. For example, the devices state of the shift-, alt-, control and |
|
145 |
meta keys are updated there. After that, the event is forwarded either to |
|
146 |
the views sensor or to the view directly (if it has no sensor). |
|
147 |
(Sensorless views are a leftover from ancient times and will sooner or |
|
148 |
later vanish - simplifying things a bit. Do not depend on views without |
|
149 |
sensors to work correctly in future versions.) |
|
150 |
||
151 |
This event processing is done by the event dispatcher process, which is |
|
152 |
launched in ST/X's startup sequence (see Smalltalk>>start). |
|
153 |
Event processing is done at a high priority, to allow keyboad processing |
|
154 |
and CTRL-C handling to be performed even while other processes are running. |

The code executed by the event process is found in startDispatch. |
293 | 156 |
|
157 |
Individual events can be enabled or disabled. The ones that are enabled |
|
158 |
by default are: |
|
1352 | 159 |
keypress / keyRelease |
160 |
buttonPress / buttonRelease / buttonMotion (i.e. motion with button pressed) |
|
161 |
pointerEnter / pointerLeave |
|
293 | 162 |
|
163 |
other events have to be enabled by sending a corresponding #enableXXXEvent |
|
164 |
message to the view which shall receive those events. |
|
165 |
For example, pointerMotion events (i.e. motion without button being pressed) |

Currently, there is are only two concrete display classes (released to the public): |
151 | 185 |
|
1191 | 186 |
XWorkstation - a plain X window interface |
187 |
||
188 |
GLXWorkstation - an X window interface with a GL(tm) (3D graphic library) |
|
189 |
extension; either simulated (VGL) or a real GL |
|
190 |
(real GL is only available on SGI machines) |
|
1122 | 191 |
|
192 |
the following are coming soon: |
|
193 |
||
1191 | 194 |
OpenGLWorkstation |
195 |
- an X window interface with a openGL(tm) (3D graphic library) |
|
196 |
extension; either simulated (MESA) or a real openGL |
|
197 |
(real openGL is only available on SGI/NT machines) |
|
198 |
||
199 |
WinWorkstation - what will that be ? |
|
151 | 200 |
|
201 |
An experimental version for a NeXTStep interface exists, but is currently |
|
202 |
no longer maintained and not released. |
|
1122 | 203 |
Also, interfaces for other graphic systems (i.e. OS/2) are |
204 |
planned for and will be available (hopefully) in late 96. |
|
151 | 205 |
|
206 |
DeviceWorkstation itself is an abstract class; the methods as defined |
|
207 |
here perform things which are common to all graphic devices or block |
|
208 |
methods and raise a subclassResponsibilty error condition. |
|
209 |
To create a new graphic interface, at least the subclassResponsibilty-methods |
|
210 |
have to be reimplemented in a concrete subclass. |

This does not work with other devices (i.e. Windows). |
151 | 217 |
|
218 |
If you want to experiment with multi-display applications, |
|
219 |
you have to: |
|
220 |
||
1191 | 221 |
- create a new instance of XWorkstation: |
222 |
||
223 |
Smalltalk at:#Display2 put:(XWorkstation new). |
|
224 |
or: |
|
225 |
Smalltalk at:#Display2 put:(GLXWorkstation new). |
|
226 |
||
227 |
||
228 |
- have it connect to the display (i.e. the xServer): |
|
229 |
(replace 'localhost' below with the name of your display) |
|
230 |
||
231 |
Display2 := Display2 initializeFor:'localhost:0.0' |
|
232 |
||
233 |
returns nil, if connection is refused |
|
234 |
- leaving you with Display2==nil in this case. |
|
235 |
||
236 |
||
237 |
- start an event dispatcher process for it: |
|
238 |
(this is now no longer needed - the first opened view will do it for you) |
|
239 |
||
240 |
Display2 startDispatch |
|
241 |
||
242 |
||
243 |
- optionally set its keyboard map |
|
244 |
(since this is usually done for Display in the startup-file, |
|
245 |
the new display does not have all your added key bindings) |
|
246 |
||
247 |
Display2 keyboardMap:(Display keyboardMap) |
|
248 |
||
249 |
||
250 |
- create a view for it: |
|
251 |
||
252 |
(FileBrowser onDevice:Display2) open |
|
253 |
||
254 |
(Workspace onDevice:Display2) open |
|
255 |
||
256 |
(Launcher onDevice:Display2) open |
|
1208 | 257 |
does not work with Launcher, since its an ApplicationModel (not a view) |
1191 | 258 |
use: |
259 |
Launcher openOnDevice:Display2 |
|
260 |
instead. |

However, as mentioned above, there may be a few places, where the default |
1191 | 263 |
display 'Display' is still hard-coded - especially, in contributed and |
264 |
Public domain code, you may find those. |
|
265 |
||
266 |
Beside this (little bug ;-), remote display operation works pretty well. |
|
267 |
If you write your application to work around those, multi-display applications are |
|
268 |
possible in the current release. |
|
269 |
||
270 |
To make your application ready for multi-display operation, replace all |
|
271 |
references to 'Display' by: 'Screen current', which evaluates to the currently |
|
272 |
active display. I.e. each view gets its actual display via this expression. |
|
273 |
Since ST/X views already use this, new views opened by remote views should |
|
274 |
come up on the remote display. |
|
151 | 275 |
|
276 |
There is no easy solution for things like Notifiers, WarnBoxes or |
|
277 |
Debuggers when opened from some background or non-view process. |
|
278 |
These will come up one the default Display, as returned by 'Screen default'. |
|
279 |
||
1191 | 280 |
There may still some problems to be expected, |
151 | 281 |
if the screens have different display capabilities (b&w vs. greyscale vs. |
282 |
color display). The current styleSheet approach keeps default values |
|
283 |
only once (it should do so per display ...) For now, expect ugly looking |
|
284 |
views in this case - or set your styleSheet for the smallest common |
|
285 |
capabilities (i.e. for b&w). |

"Return the key translated via the translation table. |

89 | 4311 |
Your application program should never depend on the values returned |
4312 |
by this method, but instead use symbolic keys (such as #FindNext). |
|
4313 |
Doing so allows easier reconfiguration by changing the translation map |
|

in the 'smalltalk.rc' or 'display.rc' startup files. |

89 | 4319 |
If multiple modifiers are active, the symbol becoms the concatenation |
4320 |
as in AltCtrlq (for control-alt-q). Shift will affect the last component, |
|
4321 |
thus the above with shift becoms: AltCtrlQ instead. |
|
4322 |
Some keyboards offer both Alt and Meta keys - on those, the first has a |
|
4323 |
prefix of Alt, the second has Cmd as prefix. Keyboards with only an Alt |
|
4324 |
key will will create prefix codes of Cmd for that. |
|
4325 |
For symbolic keys (i.e.Tab, Backspace etc, shift is ignored). |
|
51 | 4326 |
Then the result is used as a key into the translation keyboardMap |
4327 |
to get the final return value." |
