74519 - gimp.org - Java script drawn tree doesn't work correctly

Status: RESOLVED INVALID

(Tech Evangelism Graveyard :: English US, defect, P3)

Description

[Miroslav Kes]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; 0.8.1) Gecko/20010323
BuildID:    2001032319

In  the page at http://manual.gimp.org/manual/GUM/GUM.html the left frame is
supposed to display java script generated tree. Some tree is displayed but it is
damaged. The tree is too big to be displayed in the frame but no scrollbars show
up. It is impossible to expand or collapse nodes. There should be tabs at the
top of the frame which are not  displayed correctly. There is one more problem
which is not visible at that page (as the backgroud color is gray) but I
experienced that on other pages - the background of the area covered by the tree
is gray no matter what the background color of the page is.

Reproducible: Always
Steps to Reproduce:
1.Open the browser. 
2. Go to http://manual.gimp.org/manual/GUM/GUM.html
3. See what's displayed in the left frame

Actual Results:  See the description.

Expected Results:  I don't want to insult anybody but try to open that URL with
M$ Internet Explorer and you will see.

I would be able to e-mail you some HTML pages that demonstrate the problem with
backgroud color. Just send me an e-mail address.

Seeing everything the reporter describes with 2001040204 / Win98SE.

The missing scrollbars for javascript generated content are described in bug
55334. Perhaps this bug should depend on that?

Oddly, Mozilla takes ages and ages to finally render that page, eating around 4
MB of RAM (I know, there's also bug filed on that).

Dear Reporter: Please don't send me the testcases! I'm only an ordinary Bugzilla
user commenting on some bugs and *not* a developer / contributor. Thanks :-)

The Javascript code is fairly complex, to say the least. However the tree 
widget doesn't appear to have W3C DOM support.

e.g. (from http://manual.gimp.org/manual/GUM/wwhtree.js)

  if(isIE4){
    this.navObj = tabDisplay.document.all["item"+this.id];
    this.iconImg = tabDisplay.document.all["itemIcon"+this.id];
  }else if(isNav4){
    this.navObj = tabDisplay.document.layers["item"+this.id];
    this.iconImg = this.navObj.document.images["itemIcon"+this.id];
    tabDisplay.document.yPos=tabDisplay.document.yPos+this.navObj.clip.height;
  }

The browser sniffer code is:

if (navigator.appVersion.charAt(0) == "4") 
{
   if (navigator.appName == "Netscape") 
   {
      isNav4 = true;
      isIE4 = false;
      if (navigator.appVersion.indexOf("Macintosh") != -1)
         isNav4Mac=true;
   } 
   else if (navigator.appVersion.indexOf("MSIE") != -1) 
   {
      isIE4 = true;
      isNav4 = false;
   }
}

Mozilla has an appVersion beginning with 5, so neither isIE4 nor isNav4 will be 
set to true.
I presume Netscape 6 has an appVersion beginning with 6, so it won't work 
either.
IE5 has an appVersion beginning with 4, so it work work on the site.

Over to evangelism.  There is no way for that site to work with mozilla because
none of the code branches are executed.....

All Evangelism Bugs are now in the Product Tech Evangelism. See bug 86997 for
details.

I've encountered this problem under RH7.1 with mozilla 0.9.5.   Netscape 4.77
works perfectly well with the web page.

In my case, mozilla appears to hang and I have to kill it, although if I waited
long enough, it might finally come back up.

Since gimp and mozilla are both open software, one would presume this problem
could be solved with a little effort.

In Mozilla Mach-O 20030228 the tree is drawn fully expanded, cannot be collapsed.

Please note that this manual only covers GIMP 1.0 and is considered obsolete.
Some of the contents were outdated when GIMP 1.2 was released, and GIMP 2.0 is
due to be finished shortly.

A new user manual is created as a community effort, and it is planned that it
will replace the current http://manual.gimp.org. So I doubt anyone will bother
to fix the errors mentioned in this bug - the content is accessible, after all.

http://manual.gimp.org does not exist anymore - needs closed.
