[Message part 1 (text/plain, inline)]

Hello,

Whenever I try to use Emacs' built-in icons, I have some difficulty
understanding the user interface for customizing an icon. For example,
regardless of the type of icon element, all the fields have similar
labels, which makes the interface difficult to understand and use.
For instance, for Images, it is not clear that the String field is
intended to enter the image file name:

Choice: Value Menu [Images|Colorful Emojis|Monochrome Symbols|Text only]
Repeat:
INS DEL String:
INS
Plist:
INS DEL :
            Key:
            Value:
INS

Also, nothing guides you regarding usage of this complex widget.

I propose the attached patch that improves the widget used to
customize an icon. Possible ChangeLog:

2024-09-11  David Ponce  <da_vid <at> orange.fr>

	Improve usability of the widget used to customize icon.

	* lisp/cus-edit.el (custom-icon--images-sub-type)
	(custom-icon--emojis-sub-type, custom-icon--symbols-sub-type)
	(custom-icon--texts-sub-type): New constant.
	(custom-icon--type): New constant.
	(custom-icon-value-create): Use it.

With this patch, a quick help summarizes usage, and the different
fields are named according to the kind of icon element.

Here is a view of the new UI when customizing the default `button' icon:

---------------------------------------------------------------
Hide Button:
Icon elements:
- Only the first occurrence of a same element counts.
- Missing elements will take their default value.:
- At least one element should be provided with a valid value.

INS DEL Choice: Value Menu Images:
         
         Values:
         INS DEL Image filename:
         INS
         Image attributes:
         INS DEL :
                     Key: :face
                     Value: icon-button
         INS

INS DEL Choice: Value Menu Colorful Emojis:
         
         Values:
         INS DEL Emoji text: 🔵
         INS
         Emoji text properties:
         INS DEL :
                     Key: :face
                     Value: icon
         INS

INS DEL Choice: Value Menu Monochrome Symbols:
         
         Values:
         INS DEL Symbol text: ●
         INS
         Symbol text properties:
         INS DEL :
                     Key: :face
                     Value: icon-button
         INS

INS DEL Choice: Value Menu Texts Only:
         
         Values:
         INS DEL Text: button
         INS
         Text properties:
         INS DEL :
                     Key: :face
                     Value: icon-button
         INS

INS

WDYT?

Thanks!
