bugdoc compared OO and LO 6.3+

Seems to me that text was always bold. No repro not bold. Test in Windows.

Maybe it's Linux only, at least OpenOffice 3.2 on Linux displayed the text non-bold (as shown in attachment 149213 [details]).

I can't reproduce it in

only reproducible in development enviroments ??

There is a difference in LibreoOffice 6.1.4.2 TDF version vs Ubuntu version.
In the Ubuntu version it is shown as non-bold while in the TDF version it is shown as bold.

michaelweghorn> for me, text of tdf#123397 doc is shown in bold with libreoffice package 1:6.1.5~rc1-2  in debian testing

content.xml:

            <text:p text:style-name="P8">01<text:tab/>Wohnsitz des Antragsgegners oder eines Mitantragsgegners</text:p>

    <style:style style:name="P8" style:family="paragraph" style:parent-style-name="Table_20_Contents">
      <style:paragraph-properties fo:text-align="justify" style:justify-single-word="false">
        <style:tab-stops>
          <style:tab-stop style:position="0.397cm"/>
        </style:tab-stops>
      </style:paragraph-properties>
    </style:style>

styles.xml:
    <style:font-face style:name="Arial1" svg:font-family="Arial" style:font-adornments="Standard" style:font-family-generic="swiss" style:font-pitch="variable"/>

    <style:style style:name="Table_20_Contents" style:display-name="Table Contents" style:family="paragraph" style:parent-style-name="Standard" style:class="extra">
      <style:text-properties style:font-name="Arial1" fo:font-size="7pt" fo:font-weight="normal"/>
    </style:style>




so we have style:font-adornments="Standard" and fo:font-weight="normal", i don't see where the bold is supposed to come from?

styles.xml:

    <style:style style:name="Standard" style:family="paragraph" style:class="text" style:master-page-name="">
      <style:text-properties style:font-name="Arial Black" fo:font-size="10pt" fo:font-weight="900"/>
    </style:style>

somehow the fo:font-weight="900" of the parent style "Standard" is not overwritten by the fo:font-weight="normal" of the derived style "Table Contents".

if you use e.g. de_DE locale, you get "Regular" font weight.

but with en_US you get "Black" font weight.

the problem is that this style:

    <style:style style:name="Table_20_Contents_20__28_user_29_" style:display-name="Table Contents (user)" style:family="paragraph" style:parent-style-name="Standard">
      <style:paragraph-properties ns3:contextual-spacing="false" fo:margin-top="0.049cm" fo:margin-bottom="0.049cm" style:vertical-align="middle"/>
      <style:text-properties style:font-name="Arial" fo:font-size="7.5pt" style:font-name-complex="Arial" style:font-size-complex="7.5pt"/>
    </style:style>


"Table Contents (user)" will be mapped to the same internal SwTextFormatColl as the built-in style "Table Contents", but *only* if it matches the locale's translation of "Table Contents".

this could be fixed by:

1) reworking SwFormat etc. (haven't checked which of the 5-6 classes are actually subclasses of SwFormat) in Writer document model so it stores the "programmatic name" (as used in ODF/other file formats) instead of the "UIName" that is shown in the UI, and then moving the FillUIName / FillProgName conversions out of the "unocore" classes and into all UI classes that display style names.

2) making use of the SwFormat's m_nPoolFormatIds as a second part of the lookup key, so that we can store styles with same name but one has a pool-id and the other does not; not sure which/how many places would need to know whether they want a pool-style or not though.

either of these is a bit of work; anything simpler looks like it's going to cause some kind of problem or other...

Seems very minor, can be easily fixed with setting Default Style, which is empty, to Regular font style.
But Default Style should not be empty. Maybe this should be closed.
