Status: NEW

Description

[Mats Palmgren (inactive)]

Cursor glyph for CSS3 'no-drop' is the same as for 'not-allowed'.

(spawned off from bug 163174 comment 98)

The desired glyph is a hand with a small 'not-allowed' symbol next to it.

Comment 1

[Sergey Sokoloff]

I've just started working on a new glyph.

Comment 2

[Gérard Talbot]

Sergey, which program do you use to create win32 cursors? I use MicroAngelo. I
can easily convert a 32x32 .gif into a valid win32 .cur file.
I've created a custom no-drop win32 .cur; the only issue remaining is
determining the hotspot preferred in Mozilla.

With MSIE 6, you can view it

Frankly speaking, I edit the corresponding doublebytes manually after creating
the cursor.

I'll attach the specs for you here, wait a minute.

Attachment: Windows bitmaps (BMP, ICO, CUR)

To save your time, I'll summarize: 0A is X coord offset, 0C is Y coord offset
for hotspot.

Attachment: Microsoft Windows custom cursor (.CUR) for CSS3 no-drop

Open it in your favourite hex editor; the first bytes should be:

00 00 02 00 01 00 20 20 04 00 06 00 01 00 E8 02

06 and the following 01 is the hotspot: X=6, Y=1, counting from (0;0) the upper
left corner of the bitmap.

[Sergey Sokoloff]

Several differences between my version and
http://www.gtalbot.org/GRAPHICS/ICO/Custom_made_no-drop.cur are the following:

1) I used 1-pixel white halo around no-drop symbol to make it visible on black
or other dark backgrounds

2) I made hand's thumb somewhat wider, to match anatomy of average user

Reduced unnecessary bloat; now this cursor is as small in filesize as 326
bytes.

Yeah, good idea: MSIE 6 does that.

> 2) I made hand's thumb somewhat wider, to match anatomy of average user

Also, your .cur file is smaller (766 bytes, 16 colors); mine is 2238 bytes, 256
colors.

[Sergey Sokoloff]

2 colors should be enough ;-)

"
no-drop
    Indicates that the dragged item cannot be dropped at the current cursor location. Often rendered as a hand or pointer with a small circle with a line through it. 

not-allowed
    Indicates that the requested action will not be carried out. Often rendered as a circle with a line through it.

A lot of things has changed since 2006, and since I don't have access to a computer with Windows, I wonder, is this still the case?

Comment 12

[d]

Should have tried the testcase first, it's the same thing on Mac OS X. This should be switched from a Windows bug to an all OS bug, or, closed, if we feel that there is no need to have different cursors.

Comment 13

What's the right component for this bug?

Comment 14

[Gérard Talbot]

Hello,

I get expected results in 
https://www.w3.org/TR/css-ui-3/#valdef-cursor-no-drop
and
http://www.gtalbot.org/DHTMLSection/Cursors.html#CSS3


I get/see an arrow (albeit not a white hand) with a small red 'not-allowed' circle symbol on its righthand side. The spec says: "Often rendered as a hand or pointer with a small circle with a line through it." So, an arrow is fine.

I use Firefox 52.0.1 buildID=20170317212642 under 
Linux 4.8.0-42-generic x86_64 (64bit)
Qt: 5.6.1
KDE Plasma: 5.8.5
KDE development platform: 4.14.22
KDE Frameworks: 5.28
Kubuntu 16.10 (codename: yakkety)

Can anyone else please report his/her findings for Windows 7, 8, 10 and for Mac OS X 10+ ?

Another 'cursor: no-drop' test:

Comment 16

[j.j.]

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0

"no-drop" is the same as "not-allowed" for me on Win7

[Chris Mills [:cmills]]

Adding ddn so we can update the cursor property page when this is fixed.

hmm, I'm waiting for a fix since 13 years ... 
btw, why is this marked as "enhancement"? It's just a bug, no?

Severity has been set to "normal"; "enhancement" has been removed. Presumably, enhancement was added at a time when CSS3 UI spec was then in a draft state.

Priority P4 has been replaced with P3.

Can any Mac OS X users or Windows 10 report if this bug has been fixed for him/her when trying the following tests:

http://www.gtalbot.org/DHTMLSection/Cursors.html#CSS3

http://test.csswg.org/suites/css-ui-3_dev/nightly-unstable/html/cursor-007.htm

?

Thank you.

I just tried today's nightly on my OSX 10.12 Macbook and the icon is still the same for no-drop and not-allowed (a small pointer under which there is a circle with a diagonal line through it). I also get a similar results in a stock Windows 10/Edge virtual machine, though the icon is just a red circle with a diagonal line through it, without a bit of pointer-arrow.

Comment 21

[Jeremy Zhao]

[BugBot (nomail) [:suhaib / :marco/ :calixte]]

The last needinfo from me was triggered in error by recent activity on the bug. I'm clearing the needinfo since this is a very old bug and I don't know if it's still relevant.

Comment 25

[j.j.]

(In reply to Jim Mathies [:jimm] from comment #24)

I will fix it

Can you also have look on bug 204841 ?
Testcase is here: http://elektronotdienst-nuernberg.de/bugs/cursor.html

Comment 26

[[Not actually Gijs]]

I will fix it.

Comment 27

[Naci Sta]

I think, that this is issue of Windows itself and not Firefox.

Comment 28

[Red John]

Hey Naci Sta, I'm think about it, and I think, that it is issue with Firefox and not of the Windows, so stop lying.
