222888 - If "MSThemeCompatible" meta is specified and set to "No", radio buttons look ugly

Status: RESOLVED DUPLICATE of bug 16380

(Core :: Layout: Form Controls, defect)

Description

[Thomas Verelst]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5) Gecko/20031007
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5) Gecko/20031007

On Mozilla 1.4 and 1.5, when specifying <meta http-equiv=MSThemeCompatible
content=no> in the head section, a form's radio buttons get something that I can
best describe as a "speckled round border".

The only way to get around it is to sniff out Internet Explorer via JavaScript
and add the meta tag in a document.write section intended for that browser
exclusively.&nbsp; This way, Mozilla won't "see it".

Reproducible: Always

Steps to Reproduce:
1. Add <meta http-equiv=MSThemeCompatible content=no> to the head
2. Add <input type=radio> to the body
3. Check your page



Expected Results:  
Mozilla should ignore the "MSThemeCompatible" meta tag.

Reporter, we will need to see a specific URL or a testcase where you can
demonstrate this problem.

Hi.
I see someone else already did.  Should I maybe post screen shots?

Why should Mozilla ignore this? If you disable Theme support, then Mozilla will
use its internal form styles... that's what it means.

[Thomas Verelst]

The tag's purpose is to disable the themes feature in Internet Explorer 6 on
Windows XP.  This feature generally affects the look of the scrollbar as well as
buttons and input fields, which may be a problem (for the web designer) if the
page in question is intended to show up in a specific way.

I said that Mozilla should ignore this tag because it's not intended to change
anything in Mozilla.

Yes, and Mozilla has a similar feature which does very much the same thing (on
Windows XP).  That is, it will also use the Windows XP theming functionality to
style page elements.

So if the designer doesn't want IE to do that, presumably they don't want
Mozilla to do it either.  hence our support for MSThemeCompatible

[Thomas Verelst]

Hmm... OK...

But this tag doesn't affect radio buttons in Internet Explorer.  Why does it in
Mozilla?

Comment 9

[Boris Zbarsky [:bzbarsky]]

Does IE change radio button rendering when you change themes?  Mozilla does,
with the theme.

Comment 10

[Thomas Verelst]

Specifying that meta tag changes the radio buttons in Internet Explorer 6 from
the "special one" to the "regular one" if a theme is enabled.  If no theme is
enabled, it is the "regular one" either way.  On Mozilla, it changes from the
"regular one" to something that you can see in the screen shot posted above in
the attachment section.

Where does this look come from?  I cannot reproduce it with any other browser
with neither theme.

Comment 11

[Boris Zbarsky [:bzbarsky]]

The button it changes to is the "regular" one in Mozilla.  i.e. the one drawn
using Mozilla's built-in radio-button-drawing routine.

Comment 12

[Thomas Verelst]

OK, well... it does not for me.  I get what you can see in the screenshot.

Windows 2000 SP4 (English)
Mozilla 1.5 (English)

Comment 13

[Thomas Verelst]

(I checked the behavior of Internet Explorer 6 on a machine nearby running
Windows XP Pro SP1.)

Comment 14

> I get what you can see in the screenshot.

Yes... that screenshot is exactly what the built-in radio-drawing routine
produces on Windows.

Comment 15

[Thomas Verelst]

So do you suggest I cancel this bug and write a new one with a better
description?  I would only have to change the "Expected results" part to "The
radio buttons rendered by the built-in radio-button-drawing routine on Windows
when <meta http-equiv=MSThemeCompatible content=no> is specified should show up
as 'normal' radio buttons."

Comment 16

[Boris Zbarsky [:bzbarsky]]

I believe we have existing bugs on the fact the our drawing routine draws ugly
radio buttons on Windows....

Comment 17

[Thomas Verelst]

I just did a check on "radio button" and I didn't find any that deals with the
"drawing routine".  Maybe it's in bugs that were originally filed for a purpose
other than radio buttons.

If you happen to know of one, you're welcome to change this bug's status to
"duplicate".
