Hi Eric,

MorphInspector, FormInspector, and a bunch of other small new improvements to the inspector framework have arrived in the Squeak Trunk just a few months ago! See http://forum.world.st/Please-try-out-Inspector-Refactoring-td5114974.html and https://squeak.org/downloads/#current-trunk-image-2:~:text=Current-,Trunk,-Image :-)

> I find the whole relationship between a Text and TextStyle a bit confusing, especially where it comes to setting Fonts. It appears that there are lots of different "kinds" of Fonts, and there's a good amount of indirection so it's difficult to determine which kind of fonts (StrikeFont? TTFont?) "live" and how to see what's available and pick programmatically. Is there a good primer somewhere on Text/TextStyle?

These are good questions others can probably answer better than I could do.
This is all I can tell you:

  1.  Font rendering in Squeak is difficult and the default font (DejaVu Sans) appears to be the only one that looks kind of nice in all sizes. I almost never choose a different font.
  2.  To change the font in a Text, use something like:
'foo' asText
addAttribute: (TextFontReference toFont: (StrikeFont
familyName: 'Darkmap DejaVu Sans'
pointSize: 20));
openAsMorph

> Also -- how can I disable editing of a TextMorph?

See TextMorph >> #readOnly: or also Morph >> #lock to disable any interaction.

Best,
Christoph

Hi Christoph,

for displaying graphics in an inspector, have a look at MorphInspector (screenshot) or FormInspector (pixels). Custom interactive fields are not (yet?) supported, but in theory, you could subclass Inspector and override the relevant toolbuilder methods.

I can't seem to find MorphInspector in a current (5.3 here) image. Is this a separate package?


Regarding to your second question - why don't you use a TextMorphs? The composition of different formatting styles applied to a string is just what makes up a Text

Aha, yes, I think I've looked into this before. I find the whole relationship between a Text and TextStyle a bit confusing, especially where it comes to setting Fonts. It appears that there are lots of different "kinds" of Fonts, and there's a good amount of indirection so it's difficult to determine which kind of fonts (StrikeFont? TTFont?) "live" and how to see what's available and pick programmatically. Is there a good primer somewhere on Text/TextStyle? Also -- how can I disable editing of a TextMorph?

Thanks again
