events |
157 |
" |
|
158 |
All events are processed in a workstations dispatchEvent method. |
|
159 |
There, incoming events are first sent to itself, for a first (view independent) |
|
160 |
preprocessing. For example, the devices state of the shift-, alt-, control and |
|
161 |
meta keys are updated there. After that, the event is forwarded either to |
|
162 |
the views sensor or to the view directly (if it has no sensor). |
|
163 |
(Sensorless views are a leftover from ancient times and will sooner or |
|
164 |
later vanish - simplifying things a bit. Do not depend on views without |
|
165 |
sensors to work correctly in future versions.) |
|
166 |
||
167 |
This event processing is done by the event dispatcher process, which is |
|
168 |
launched in ST/X's startup sequence (see Smalltalk>>start). |
|
169 |
Event processing is done at a high priority, to allow keyboad processing |
|
170 |
and CTRL-C handling to be performed even while other processes are running. |
|
1697 | 171 |
The code executed by the event process is found in #startDispatch. |
293 | 172 |
|
173 |
Individual events can be enabled or disabled. The ones that are enabled |
|
174 |
by default are: |
|
3397 | 175 |
keypress / keyRelease |
176 |
buttonPress / buttonRelease / buttonMotion (i.e. motion with button pressed) |
|
177 |
pointerEnter / pointerLeave |
|
293 | 178 |
|
179 |
other events have to be enabled by sending a corresponding #enableXXXEvent |
|
180 |
message to the view which shall receive those events. |
|
181 |
For example, pointerMotion events (i.e. motion without button being pressed) |

However, as mentioned above, there may be a few places, where the default |
1191 | 281 |
display 'Display' is still hard-coded - especially, in contributed and |

Public domain code, you may find those. |
|

Beside this (little bug ;-), remote display operation works pretty well. |
|
285 |
If you write your application to work around those, multi-display applications are |
|

where up to 6 x-terminals are connected to a single linux PC). |
1191 | 288 |
|
289 |
To make your application ready for multi-display operation, replace all |
|
290 |
references to 'Display' by: 'Screen current', which evaluates to the currently |
|
291 |
active display. I.e. each view gets its actual display via this expression. |
|
292 |
Since ST/X views already use this, new views opened by remote views should |
|
293 |
come up on the remote display. |
|
151 | 294 |
|
295 |
There is no easy solution for things like Notifiers, WarnBoxes or |
|
296 |
Debuggers when opened from some background or non-view process. |
|
297 |
These will come up one the default Display, as returned by 'Screen default'. |

"Return the key translated via the translation table. |
|
5976 |
Your application program should never depend on the values returned |
|
5977 |
by this method, but instead use symbolic keys (such as #FindNext). |
|
5978 |
Doing so allows easier reconfiguration by changing the translation map |
|
5979 |
in the 'smalltalk.rc' or 'display.rc' startup files. |
|
5980 |
||
5981 |
First, the modifier is prepended, making character X into |
|
5982 |
AltX, CtrlX or CmdX (on many systems, no separate Cmd (or Meta) |
|
5983 |
key exists; on those we always get AltX if the metaModifiers are not set correctly). |
|
5984 |
If multiple modifiers are active, the symbol becoms the concatenation |
|
5985 |
as in AltCtrlq (for control-alt-q). Shift will affect the last component, |
|
5986 |
thus the above with shift becoms: AltCtrlQ instead. |
|
5987 |
Some keyboards offer both Alt and Meta keys - on those, the first has a |
|
5988 |
prefix of Alt, the second has Cmd as prefix. Keyboards with only an Alt |
|
5989 |
key will will create prefix codes of Cmd for that. |
|
5990 |
For symbolic keys (i.e.Tab, Backspace etc, shift is ignored). |
|
5991 |
Then the result is used as a key into the translation keyboardMap |
|
5992 |
to get the final return value." |
