Bug ID: 165507
Summary: Properly support Start and End text alignment,
correctly support Right and Left
Product: LibreOffice
Version: Inherited From OOo
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: [email protected]
Reporter: [email protected]
The ODF standard supports [1] six alignment settings for text in a paragraph:
* start
* end
* left
* right
* center
* justify
At the moment, LO "supports" four of those, and actually - doesn't even really
support those four:
* There is no UI in the Paragraph Style / Paragraph Formatting dialog choosing
Start or End alignment.
* When choosing Left or Right, LO often (always?) actually chooses Start or
End, in terms of what's written to the ODT file. For example, if you create a
Writer document with four paragraphs: LTR,left-align, LTR,right-align,
RTL,right-align and RTL,left-align (with the first one inheriting the page
style), you get this in an FODT output:
<style:style style:name="P1" style:family="paragraph"
style:parent-style-name="Standard">
</style:style>
<style:style style:name="P2" style:family="paragraph"
style:parent-style-name="Standard">
<style:paragraph-properties fo:text-align="end"
style:justify-single-word="false"/>
</style:style>
<style:style style:name="P3" style:family="paragraph"
style:parent-style-name="Standard">
<style:paragraph-properties fo:text-align="end"
style:justify-single-word="false" style:writing-mode="rl-tb"/>
</style:style>
<style:style style:name="P4" style:family="paragraph"
style:parent-style-name="Standard">
<style:paragraph-properties fo:text-align="start"
style:justify-single-word="false" style:writing-mode="rl-tb"/>
</style:style>
So, let's do the following:
* Have the UI show all six options, at least when RTL support is fully enabled.
* Save what the user has actually asked for, to the file.
* Rework the four-button group of alignments into a six-group button, with the
appropriate names, tooltips and help text.
The dilemmas are:
1. What to do when RTL support is _not_ enabled - whether to maintain the "Use
Start even though the user said Left" convention.
2. Whether to show the six buttons on the toolbar, only only the 4 buttons of
S,E,J,C and keep the other off the toolbar by default.
3. What button images to use for proper Left and Right vs Start and End.
