events |

|
157 |
All events are processed in a workstations dispatchEvent method. |
|
158 |
There, incoming events are first sent to itself, for a first (view independent) |
|
159 |
preprocessing. For example, the devices state of the shift-, alt-, control and |
|
160 |
meta keys are updated there. After that, the event is forwarded either to |
|
161 |
the views sensor or to the view directly (if it has no sensor). |
|
162 |
(Sensorless views are a leftover from ancient times and will sooner or |
|
163 |
later vanish - simplifying things a bit. Do not depend on views without |
|
164 |
sensors to work correctly in future versions.) |
|
165 |
||
166 |
This event processing is done by the event dispatcher process, which is |
|
167 |
launched in ST/X's startup sequence (see Smalltalk>>start). |
|
168 |
Event processing is done at a high priority, to allow keyboad processing |
|
169 |
and CTRL-C handling to be performed even while other processes are running. |
|
1697 | 170 |
The code executed by the event process is found in #startDispatch. |
293 | 171 |
|
172 |
Individual events can be enabled or disabled. The ones that are enabled |
|
173 |
by default are: |

However, as mentioned above, there may be a few places, where the default |
1191 | 276 |
display 'Display' is still hard-coded - especially, in contributed and |
277 |
Public domain code, you may find those. |
|

Beside this (little bug ;-), remote display operation works pretty well. |
|
280 |
If you write your application to work around those, multi-display applications are |
|

possible in the current release (and actually being used in a concrete application, |

where up to 6 x-terminals are connected to a single linux PC). |
1191 | 283 |
|
284 |
To make your application ready for multi-display operation, replace all |
|
285 |
references to 'Display' by: 'Screen current', which evaluates to the currently |
|
286 |
active display. I.e. each view gets its actual display via this expression. |
|
287 |
Since ST/X views already use this, new views opened by remote views should |
|
288 |
come up on the remote display. |
|
151 | 289 |
|
290 |
There is no easy solution for things like Notifiers, WarnBoxes or |
|
291 |
Debuggers when opened from some background or non-view process. |
|
292 |
These will come up one the default Display, as returned by 'Screen default'. |

"Return the key translated via the translation table. |

Your application program should never depend on the values returned |
4990 |
by this method, but instead use symbolic keys (such as #FindNext). |
|
4991 |
Doing so allows easier reconfiguration by changing the translation map |
|

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

key exists; on those we always get AltX if the metaModifiers are not set correctly). |
89 | 4997 |
If multiple modifiers are active, the symbol becoms the concatenation |
4998 |
as in AltCtrlq (for control-alt-q). Shift will affect the last component, |
|
4999 |
thus the above with shift becoms: AltCtrlQ instead. |
|
5000 |
Some keyboards offer both Alt and Meta keys - on those, the first has a |
|
5001 |
prefix of Alt, the second has Cmd as prefix. Keyboards with only an Alt |
|
5002 |
key will will create prefix codes of Cmd for that. |
|
5003 |
For symbolic keys (i.e.Tab, Backspace etc, shift is ignored). |
|
51 | 5004 |
Then the result is used as a key into the translation keyboardMap |
5005 |
to get the final return value." |
