The first one was a question that I asked, and the second was an<br>
answer by Marcel Taeumel. I was able to decypher almost all his<br>
pointers - but not yet this one:<br>
<br>
HandMorph >> #generateKeyboardEvent:<br>
<br>
I am using this code:<br>
<br>
a := Array with: 50@100 with: 200@300 with: 100@400.<br>
b := (PolygonMorph<br>
vertices: a color: Color red<br>
borderWidth: 1 borderColor: Color black).<br>
World addMorph: b.<br>
<br>
b beSmoothCurve.<br>
b beStraightSegments.<br>
<br>
b vertices.<br>
b vertices at: 1.<br>
b vertices at: 1 put: 40@100.<br>
b vertices at: 1 put: 50@100.<br>
b vertices at: 1 put: 40@100. b computeBounds.<br>
b vertices at: 1 put: 50@100. b computeBounds.<br>
<br>
b color.<br>
b color: Color banana.<br>
b color: Color red.<br>
<br>
e := EventHandler new.<br>
b eventHandler.<br>
b eventHandler: nil.<br>
b eventHandler: e.<br>
<br>
bl := [ :a :b | { a . b }].<br>
bl := [ :a :b | Transcript show: { a . b }; cr. ].<br>
bl numArgs.<br>
bl value: 2 value: 3.<br>
bl perform: #value:value: with: 2 with: 3.<br>
<br>
bl := [ :evt :sm | Transcript show: { evt . sm }; cr. ].<br>
bl := [ :evt :sm | Transcript show: { evt keyValue . sm }; cr. ].<br>
bl := [ :evt :sm | self halt. ].<br>
e on: #keyStroke send: #value:value: to: bl.<br>
b currentHand newKeyboardFocus: b.<br>
<br>
It is meant to be used in a workspace. By selecting the right parts of<br>
it and running them with "do it"s or "print it"s in the right order I<br>
can create a PolygonMorph, some EventHandlers, and some blocks, and<br>
then I can make the PolygonMorph react to keyboard events in different<br>
ways. The last line switches the keyboardFocus to my PolygonMorph, and<br>
then I can send several keystroke events to my PolygonMorph, and<br>
inspect their events either on the transcript or on the debugger.<br>
<br>
Question: suppose that evt is an event whose printed representation is<br>
this one:<br>
<br>
[79@273 keystroke ' ' (32) 956759]<br>
<br>
I know that this means that:<br>
<br>
evt position -> 79@273<br>
evt type -> #keystroke<br>
evt keyValue -> 32<br>
evt keyCode -> 32<br>
evt source -> self currentHand<br>
evt timeStamp -> 956759<br>
<br>
How do I write code that creates an event like that? I would like to<br>
create, ahem, "synthetic keystrokes", and experiment with sending them<br>
to certain morphs...<br>
<br>
Thanks in advance!<br>
