One might encounter all kinds of nasty debuggers just because one does not know about the challenges of multi-processing and shared data structures and so on. Just because ST-80 MVC did not even try to support you in this regard does not imply that it is better compared to Morphic. At least, Morphic gives you something to work with.</span></span></div><div><span style="font-family: Arial, Helvetica, sans-serif"><span style="font-size: 13px"><br></span></span></div><div><span style="font-family: Arial, Helvetica, sans-serif"><span style="font-size: 13px">It is so funny how people react to things they do not yet know much about.

Fantastic, thanks! =)<br>
I added this to the class in which I'm putting most of my stuff,<br>

!See class methodsFor: 'as yet unclassified' stamp: 'Edrx 2/22/2023 02:54'!<br>

target: aBlock;<br>
actionSelector: #value;<br>
addAlarm: #doButtonAction after: ms.<br>

<br>
and now I can simply run this<br>

See run: [ kf := self currentHand keyboardFocus ] after: 5000.<br>
<br>
to save into the variable kf the morph on which the keyboard focus is<br>
after 5 seconds. Neat! =)<br>

<div>Hi,</div>
<div>A morph has to be in the world to be able to interact with it; eg. #openInWorld.<br>
</div>
<div><br>
</div>
<div>If you don't want to see the morph you can send it message #hide. It makes the morph invisible but it's still in the world and can interact with it.<br>
</div>
<div>To see the morph again send #show.</div>
<div>To delete the morph send #delete. The morph will be garbage collected.<br>
</div>

<div dir="ltr">Hi Vanessa!<br>
Thanks! =) This works in a workspace,<br>
<br>
"Create a SimpleSwitchMorph with label 'Toggle'<br>
and a SimpleButtonMorph with label 'Flash'.<br>
The button will be placed below the switch."<br>
<br>
sm := SimpleSwitchMorph new.<br>
sm openInWorld.<br>
bm := SimpleButtonMorph new.<br>
bm openInWorld.<br>
bm position: bm position + (0@32).<br>
<br>
"Three ways of toggling the color of the switch:"<br>
<br>
sm toggleState.<br>
<br>
bl := [ sm toggleState ].<br>
bl value.<br>
<br>
bm target: bl.<br>
bm actionSelector: #value.<br>
bm doButtonAction.<br>
<br>
"Two ways of toggling the switch after 1000ms:"<br>
<br>
sm addAlarm: #toggleState after: 1000.<br>
bm addAlarm: #doButtonAction after: 1000.<br>
<br>
but this doesn't:<br>
<br>
bm2 := SimpleButtonMorph new.<br>
bm2 target: bl.<br>
bm2 actionSelector: #value.<br>
bm2 addAlarm: #doButtonAction after: 1000.<br>
<br>
What is the right way to add an alarm to a morph that is not shown on<br>
the screen? Also, can I create a new invisible morph every time that I<br>
want to run an alarm? Are they going to be garbage collected?<br>
<br>
Thanks in advance!<br>

<div>The best way to do this in Morphic is with "alarms":</div>

</div>
<div> self addAlarm: #changeKeyboardFocus after: 5000.<br>

<div>The way of sleeping you suggest is possible too but more tricky, since you would have to move your wait code to an extra process to not block the UI process, but then make sure that the actual work is done in the UI process again (Morphic is not multithreaded,
although Squeak is).</div>

<div dir="ltr">Hi list,<br>
<br>
a few days ago I asked for help on how to send a "synthetic" keyboard<br>
event to a morph, and Karl Ramberg gave me exactly the right hints in<br>
this thread:<br>
<br>
<a href="http://lists.squeakfoundation.org/pipermail/squeak-dev/2023-February/223473.html" target="_blank">http://lists.squeakfoundation.org/pipermail/squeak-dev/2023-February/223473.html</a><br>
<br>
My code is ready except for documentation and comments - I'll work on<br>
that in the next few days and then post the result here and on the<br>
wiki...<br>
<br>
...but there's a feature that I want to add to it that - again =( -<br>
needs something that I'm not being able to discover by myself. How do<br>
I write a line of code that waits for 5 seconds, sort of like running<br>
"sleep 5" in a shell, and that doesn't block the rest of the system?<br>
If I have that I'll be able to run these two lines in a workspace,<br>
<br>
self mySleep: 5000.<br>
kf := self currentHand keyboardFocus.<br>
<br>
switch the keyboard focus to something else by clicking on it, and<br>
then the variable kf will be set to this "something else"...<br>
<br>
Thanks in advance!<br>
