superscript/subscript minor behavior glitches

[Andrei Arici]

In version 0.48.3.1 r9886, if no text is selected, subperscript and subscript buttons toggle text to 7.8 and then between 7.8 and 12 points, despite an 40 points text initial size. Things work well if you select text.

I suggest dissabling buttons while there is no text selected or modify behavior - super/subscript text relative to current font size for the next input leaving currently available text intact as right now everything is reduced to 7.8 and untogling will only result in setting it to 12.

Note: font sizes in Inkscape are px not pt (see tooltip of the font size selector). Request for additional unit selector already filed and tracked elsewhere.

Expected behavior (quoting the manual):
«Superscripts and subscripts can be created by selecting text and clicking on the corresponding icons ( icon , icon ) in the Tool Controls.

The selected text will be shifted up or down and reduced in size. Superscripts and subscripts can be removed by selecting and then clicking on the same icons. Inkscape implements superscripts and subscripts by setting the baseline-shift attribute to either “super” or “sub”, and by setting the font-size attribute to 65%. Inkscape will only recognize a superscript or subscript if the baseline-shift attribute is set in this manner. The font size can be changed after the superscript or subscript is created. The baseline-shift attribute is not supported by all browsers (e.g. Firefox 4). As a workaround, one can manually shift the text vertically.»

Thanks for the headsup regarding px and points.

However I really don't think the "expected behavior" is a correct behavior.

Suppose I've written something and now I want the next character to be superscripted. I now have 3 options:

1. Click superscript before writing anything - which reduces everything to 7.8 px. - this is plain wrong.

2. Or write that character
 - then select it
- then click superscript
- then deselect it (because if I start typing I overwrite)
- than to my surprise everything is superscript so I have to select text again
- un-superscript it
- deselect it and start typing.

3. Being aware of the faulty behavior we select chars in the middle only.

Suggested behavior: the next chars after clicking superscript ought to be 66 % of the previous character.

If I hit the "B" button (bold) all the text in the text-object turns bold. If I am to hit superscript at some point, I'd say I'd only want the next char to be super. But everything get's shrinked - and not to 65% of the original, but to 65% of 12 px. It's twice faulty.

I got an even weirder result.

Write a character
- then select it
- then click superscript
- then deselect it (I deselected whole text object and reselected it)
- then to my surprise everything is superscript so I have to select text again
- un-superscript it
- now the un-superscripted text is *above* the superscripted text so there are three levels of super duper fun

I set this to Confirmed.
