events |
166 |
" |
|
6099 | 167 |
All events are processed in a workstation's dispatchEvent method. |
293 | 168 |
There, incoming events are first sent to itself, for a first (view independent) |
6099 | 169 |
preprocessing. For example, the device's state of the shift-, alt-, control and |
293 | 170 |
meta keys are updated there. After that, the event is forwarded either to |
6099 | 171 |
the view's sensor or to the view directly (if it has no sensor). |
293 | 172 |
(Sensorless views are a leftover from ancient times and will sooner or |
173 |
later vanish - simplifying things a bit. Do not depend on views without |
|
174 |
sensors to work correctly in future versions.) |
|
175 |
||
176 |
This event processing is done by the event dispatcher process, which is |
|
177 |
launched in ST/X's startup sequence (see Smalltalk>>start). |
|
6099 | 178 |
Event processing is done at a high priority, to allow keyboard processing |
293 | 179 |
and CTRL-C handling to be performed even while other processes are running. |
1697 | 180 |
The code executed by the event process is found in #startDispatch. |
293 | 181 |
|
6296 | 182 |
Individual events can be enabled or disabled. |
6099 | 183 |
The ones that are enabled by default are: |
6296 | 184 |
keypress / keyRelease |
185 |
buttonPress / buttonRelease / buttonMotion (i.e. motion with button pressed) |
|
186 |
pointerEnter / pointerLeave |
|
6099 | 187 |
|
188 |
Other events have to be enabled by sending a corresponding #enableXXXEvent |
|
293 | 189 |
message to the view which shall receive those events. |
190 |
For example, pointerMotion events (i.e. motion without button being pressed) |

The above is only of interest, if you write your own widget classes; |
293 | 194 |
existing widgets set things as required in their #initEvents method. |

In ST/X, all interaction with the graphics device is done through |
|
201 |
an instance of (a subclass) of DeviceWorkstation. |
|
202 |
Every view has a reference to the device it has been created on in |
|
4350 | 203 |
its 'device' instance variable. |
151 | 204 |
|
205 |
One particular device instance is bound to the global variable Display: |
|
206 |
this is the default graphics display, on which new views are created |
|
207 |
(however, provisions exist for multi-display operation) |

However, as mentioned above, there may be a few places, where the default |
1191 | 290 |
display 'Display' is still hard-coded - especially, in contributed and |
291 |
Public domain code, you may find those. |

Beside this (little bug ;-), remote display operation works pretty well. |
1191 | 294 |
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 | 297 |
|
298 |
To make your application ready for multi-display operation, replace all |
|
299 |
references to 'Display' by: 'Screen current', which evaluates to the currently |
|
300 |
active display. I.e. each view gets its actual display via this expression. |
|
301 |
Since ST/X views already use this, new views opened by remote views should |
|
302 |
come up on the remote display. |
|
151 | 303 |
|
304 |
There is no easy solution for things like Notifiers, WarnBoxes or |
|
305 |
Debuggers when opened from some background or non-view process. |
|
306 |
These will come up one the default Display, as returned by 'Screen default'. |

Finally, your application should care for I/O errors (i.e. lost connection when |

There may still some problems to be expected, |
151 | 331 |
if the screens have different display capabilities (b&w vs. greyscale vs. |
332 |
color display). The current styleSheet approach keeps default values |
|
4350 | 333 |
only once (it should do so per display ...) |
334 |
For now, expect ugly looking views in this case - or set your styleSheet |

"Return the key translated via the translation table. |
|
7145 |
Your application program should never depend on the values returned |
|
7146 |
by this method, but instead use symbolic keys (such as #FindNext). |
|
7147 |
Doing so allows easier reconfiguration by changing the translation map |
|
7148 |
in the 'smalltalk.rc' or 'display.rc' startup files. |
|
7149 |
||
7150 |
First, the modifier is prepended, making character X into |
|
7151 |
AltX, CtrlX or CmdX (on many systems, no separate Cmd (or Meta) |
|
7152 |
key exists; on those we always get AltX if the metaModifiers are not set correctly). |
|
7153 |
If multiple modifiers are active, the symbol becoms the concatenation |
|
7154 |
as in AltCtrlq (for control-alt-q). Shift will affect the last component, |
|
7155 |
thus the above with shift becoms: AltCtrlQ instead. |
|
7156 |
Some keyboards offer both Alt and Meta keys - on those, the first has a |
|
7157 |
prefix of Alt, the second has Cmd as prefix. Keyboards with only an Alt |
|
7158 |
key will will create prefix codes of Cmd for that. |
|
7159 |
For symbolic keys (i.e.Tab, Backspace etc, shift is ignored). |
|
7160 |
Then the result is used as a key into the translation keyboardMap |
|
7161 |
to get the final return value." |
