[VW7.8] Image turns irresponsive with more than one error notification(?) - more info

Some more information:

When such an error occurs, the first notification dialog shows some text for a split second (until the other notifications come up, I guess).

The Windows task manager shows no activity of the Smalltalk process.

Event-faithful debugging does not change anything.

This is on Win7 64bit with a quad-core processor.

Really hope that this can be resolved….

Is there any way you might be able to modify the default handler for the
UnhandledException so that it dumps e.g.: thisContext printStack to a
file before opening the notifier?

Are you using the 64-bit VM, in preview for Windows?

Maybe you can follow the instructions here to get some more debugging info:

No, I’m using the regular 32bit VM.

Every time I've seen something like this, it's been related to code that is trying to update some Window, and failing - revealing the Window generates the error again (rinse, repeat).

Re: [VW7.8] Image turns irresponsive with more than one error notification(?) - more info

In reply to this post by Christian Haider

Thank you for this tip. This narrows it down a bit. Among the errors I expected there was one with the following trace:

Pixmap(Object)>>doesNotUnderstand:
InputState>>processUnknownEvent:for:
InputState>>send:noOp:
InputState>>process:
InputState>>run
optimized [] in InputState class>>install
BlockClosure>>on:do:
optimized [] in Process class>>forBlock:priority:

This seems to hang the image.
The #printStack message does not provide too much info. If you know something simple to print more info, let me know and will send you the results.

The situation in my app (only exemplary, since I think that problem occurred in other circumstances):
I fork off of a number of requests to a data provider.
When an answer comes back I display the result. The displaying method had a simple error (MNU).
Usually I get a notifier for each of the errors, which is what I want.
But sometimes, unfortunately not deterministic, the image locks up - presumable with the error above.
I tried to find a reproducible case in a vanilla visual.im, but have not succeeded so far.

Cheers,
Christian

Programmatically setting a font

In reply to this post by Andres Valloud-6

I've dug around a bit and can't seem to figure out how to set a font programmatically. For example, how would I change the font for the TextEditorSpec at the end of this script? Thanks.

Re: Programmatically setting a font

Any time. There are a lot of subtleties in the world of TextAttributes, CharacterAttributes, FontDescriptions etcetera, but this should give you some idea on where to start pulling the strings.

Toolbar images

In reply to this post by Carl Gundel

I'm trying to create a window with a toolbar. I have one working in Pollock/Widgetry and I'm trying to port. So this looks straightforward but I can't make it work.

In the menu editor I click on the Details tab for a menu item. Then I specify a class and selector for getting my image. I should be able to specify any class and a selector which returns an instance of a subclass of Image, right? I install the resulting definition on my window. The toolbar appears, but the image doesn't (it looks like a dot). I go back to look at the Details tab for that item in the menu, and I see that the class (and sometimes the selector) do not stick. The image displays fine in an inspector.

I'm quite frustrated. This sort of thing should be dead simple to do. Is there a tutorial for this anywhere?

Any help appreciated. Thanks,

-Carl

Re: Toolbar images

I don't think I ever did a screencast on basic toolbar use, but look at class VisualLauncher. It has one, and you can do what it does. iirc, the images have to be a specific size.

I *think*... I didn't follow this thru the debugger yet, but I think the class has to respond to visualFor:. Where the nominal implementation for that is to simply do a ^self perform: theArgument. IOW, I note that I can't just put Announcer and toolListIcon there. But If I put BehaviorIcons and the selector #Model in it, it works, because the AlphaBlendedIcons resource class implements visualFor: as a sort of bw compat for this unfortunate need.

I wish it weren't so, I'll see if I can't figure out an elegant/safe way to lift this restriction.

Re: Toolbar images

Thanks Travis, but the class I'm specifying is a subclass of ApplicationModel. That seems to meet the requirement of implementing visualFor:. Any other ideas?

Re: [7.4] Toolbar images

In reply to this post by jarober

James,

If I open the menu editor on the launcherToolbar method on class VisualLauncher, there are no images specified on the Details tab. Pretty mysterious.

I forgot to mention that I'm doing this in VW 7.4 if that matters.

Re: Toolbar images

In reply to this post by Carl Gundel

So the method should be sent to your ApplicationModel subclass. I have never went this way but I
don't see why it shouldn't work. Just to make sure that the basic assumptions are correct: Place a
breakpoint at your resource method (the one returning the picture, must be a class method otherwise
it won't work, since #visualFor: asks the app which is the class at that point), then run the
ApplicationModel. You can also try the MenuEditor but it might be protected against exceptions. If
the breakpoint fires, the problem must be with the graphic. If it doesn't fire, then we must check
out why #visualFor:

What's the result of your picture resource method? To have the same behavior as expected for other
toolbar icons, you should return an OpaqueImageWithEnablement of size 20x20 px.
My approach is always a bit different. In general, I extend ToolbarIconLibrary and add the typical
resource methods on its class side, something like #myIcon20x20 and #myIcon20x20mask.
ToolbarIconLibrary is a good container for that kind of stuff and I can reuse all the caching
behavior. Then I use it in the MenuEditor, with class = ToolbarIconLibrary and selector #myIcon.
Note the resource method name change! ToolbarIconLibrary always appends the suffix 20x20 to the
logical name before it accesses its real resource methods.
Hope that helps...

Thanks Holger, your advice turned out to be the easiest to make work.
