Squeak clock face

Hi,

I'm toying with the idea of making a clock program in Squeak to run on a Raspberry Pi Zero W. I
would like to have a full screen display of the face of the clock sans hands and have the hands
display over the clock face and move with the time. Can someone please point me in the right
direction as to Squeak objects to define and control the display.

I will probably use Seaside to allow web access to the settings of the program. Things like
timezone and maybe replacement clock faces and hands.

Re: Squeak clock face

There once was a WatchMorph

then in 2013 it was removed

"These classes don't seem to be used, so unload them. They always can be loaded later."

(MCPackage named: 'Morphic-CandidatesForGo') unload .

While I cannot give you what you want, I'd just like to point out that the Trunk image actually has

a WatchMorph (see screenshot), maybe you can fiddle something with it?

Cool. Using metacello, it should load in 5.1 and Trunk as well.

Things like
timezone and maybe replacement clock faces and hands.

You might like to grab the code that Bob helped me with for the weather station barometer/thermometer gauges.
http://www.squeaksource.com/WeatherStation.html
Oh, wait, the dial stuff is RotaryDialMorph which is in Morphic-Extras-Widgets which ought to be in the trunk image for now.

The ClockDialMorph looks like what I want. I may add a second hand if that isn't too hard and
doesn't slow down the display.

The morphs are completely new to me, so is there a simple way I can instantiate a
ClockDialMorph and test/play with it?

Thanks again.

ClockDialMorph new openInWorld

Right now it doesn’t scale with the halo handles; if anyone wants to improve that it would be nice. Adding a second hand shouldn’t present too many problems (basically add an instvar, make it pretty much a copy of what the hourHandMorph is/does but skinnier, add rotating it a bit to the #setTime: method)

I did some digging and found openInWorld. I am working on my own ClockImageMorph where the
face and the three hands will be images read from the disk. Trying to figure out how to read
the images now. I want the user to be able to install their own images. So, I don't want to
have them imbedded in the Squeak image. I'm trying to learn how to read the graphics into a
morph now.

ClockDialMorph new openInWorld

Or, even simpler, just get a sample instance from the System Browser:

There are undoubtedly a few ways to handle this (as answered by other folks already). One way to do this is to open the desktop menu (click on background), then open objects(o) menu, choose the 'find' option, and search for clock. The non-digital clock is the clock face - if you drag it out, you it will be instantiated and ready to play with.

Also, you asked how to read an image into a Morph. You can just drag the image file onto the Squeak desktop, and it should give you a variety of options, including 'open in a window', which imports it as a SketchMorph visible in Squeak.

Squeak clock face

In reply to this post by Hannes Hirzel

Hi Everyone,

Thanks for all the help so far. I'm able to read/load a picture from disk to use as the clock
face. For now I'm making the hands in much the same way they are made in ClockDialMorph. I
will replace that with pictures read in the same way the clock face is read. I'm having some
trouble with the way the hands rotate around their origin/corner point. I vaguely remember an
old discussion about this kind of thing. I will search for any info I can find on that. I
need to solve this because the user will need to specify a point on the hands that they rotate
around and I will need to use that point.

Squeak clock face

In reply to this post by Hannes Hirzel

Hi Guys,

Thanks to all your help I am well past reading in images and using them as clock faces and
clock hands. BUT I am having trouble rotating things around a point in the middle of a clock
hand. Either I don't understand what I'm doing (which is most likely) or something is wrong.

While trying to understand what happens when a morph is rotated, I have looked at the position
of things. Positions seems to be based on the real screen and not where things are within
another morph. Is it possible to find out where a morph is within its parent?

Hi Bob,

Thanks for the help. But owner position is always 0@0. Maybe I should try to ask a big
picture question. I have sub-classed RotaryDialMorph similar to Tim's ClockDialMorph. Tim has
the hands (minute and hour) rotate around one of their ends. I'm trying to get them to rotate
around a point say 20 pixels in from that end. How should I do this?

Take a look at ClockDialMorph>>initialize and how that needle is created, positioned, and wrapped with a transformationmorph - which is in turn positioned.

Take a look also at Barometer (etc) morph>>initialize to see how the fancy needle is created and positioned

Unfortunately back in April of this year we pretty much established that the rotationCenter stuff was broken and had been for a looooooooooooooooooooooooong time.

Re: Squeak clock face

Well, I think is for eToys Players and in that works well, to test use this in workspace:

attrs := {{100 . Color red . 0.5@0.5} . {200 . Color blue . 0.25@0.25}}..
hands := attrs collect: [:att| |lm|
lm := LineMorph from: 150@300 to: (Point x: 150+(att at:1) y: 300) color: (att at: 2) width: 2.
lm rotationCenter: (att at: 3).
lm makeForwardArrow].
hands do: [:m | m openInWorld].

and then create 2 (eToy) scripts to rotate, I am enclosing a movie (344kb), I hope is not rejected:

Hi Tim,

Can you please explain what this does:

pointerMorph position: pointerMorph extent * ( -0.5@ -0.65).

especially what does "* ( -0.5@ -0.65)" do and why and what do -0.5 and -0.65 relate to?

Thanks.

Lou
