Bug #16641
closed
The "click-to-enlarge" function of the image content element does not provide scrollbars to the new window.
0%
Description
This concerns the "click-to-enlarge" function of the "image" content element as well as the "text+image" content element. The issue is that the script "class.tslib_content.php" does not provide the opportunity to activate scrollbars to the picture window. The window that opens on a click is not scrollable if the picture is large as the screen size!
This concerns all versions of Typo3 starting from 3.6 (the oldest I tried) and up to the latest 4.0.2
Suggested solution:
First, let's introduce two more parameters to define the window width and height and a third parameter which contains the options for the window (i.e. "scrollable=..." and so on). They are configurable by TypoScript. Therefore insert the following code six lines beneath "if ($conf['JSwindow'])" into the function "imageLinkWrap($string,$imageFile,$conf)":
if ($conf['window_width']) {
$dims[0] = $conf['window_width'];
}
if ($conf['window_height']) {
$dims[1] = $conf['window_height'];
}
if ($conf['JSwindow.']['parameter']) {
$windowparams = $conf['JSwindow.']['parameter'];
}Then, change the line
htmlspecialchars('openPic(\''.$GLOBALS['TSFE']->baseUrlWrap($url).'\',\''.($conf['JSwindow.']['newWindow']?md5($url):'thePicture').'\',\'width='.($dims[0]+$offset[0]).',height='.($dims[1]+$offset[1]).',status=0,menubar=0\'); return false;').(which is some lines beneath the above) to
htmlspecialchars('openPic(\''.$url.'\',\''.($conf['JSwindow.']['newWindow']?md5($url):'thePicture').'\',\'width='.($dims0+$offset0).',height='.($dims1+$offset1).','.$windowparams.'\'); return false;').

I just wanted to ask the developers to insert that code into the script to make the system better and more functional. Is it possible to implement that code with the next release of typo3?

Hi Gernot, I think what Michael is saying is there is no way for the devs to apply your patch as we do not know where to apply the code you submitted, you should submit a patch in the form of a diff for the developers to work with, you should find the url's below helpful for learning how todo this.

I uploaded the diff-file for my suggestion. It should be applied to "class.tslib_content.php" in typo3_src/typo3/sysext/cms/tslib/.
Thank you very much for your help!

The patch misses a context, you can enable this using the "-u" parameter when running "diff". But anyway, I wonder why you have dropped the call of baseUrlWrap()? Did you just forget it?
After all I don't like this solution very much because it seems so static to me. On an 800x600 screen the scrollbars are needed much sooner than with a higher resolution.
Since I remember that there is a possibility to find this out using JavaScript, I would prefer such a solution much more. And you?

I think I just forget the baseUrlWrap(). It should be inserted again!
I am not a developer or a programmer, so I don't know what is static or not static. Sorry for that. I am just an admin for typo3 sites. And as an admin I missed the scrollbars when opening a new picture window. I need the scrollbars for example for showing my visiters picture in panorama format, which is twice the screen size or more (even in high resolution). Without screenbars the visitor can't see the whole picture.
As I understand the "click-to-enlarge" function, when clicking on an image the javascript function "openPic(url,winName,winParams)" is called which creates a new window via "window.open(url,winName,winParams)". The last parameter are the options for the new window. The "class.tslib_content.php" script sets this parameter to "status=0,menubar=0". That is static! The admin has no possibility to change this via typoscript or something else. The only solution is to change the code of "class.tslib_content.php".
So the main concern of my report was to point out this problem to the developers. You are right, my suggested solution is the simplest, but that's what I could do in my typo3 installation to solve that problem. Perhaps the developers could find a more sophisticated solution to make the window parameters configurable through typoscript. Maybe it is also possible to introduce a new field or butten next to the "click-to-enlarge" box in the BE which provides these options?
What do you think?
PS: Perhaps I am wrong here with my question, because it is no real bug!? I also submitted this question to the typo3-dev mailinglist, but until now nobody answered to that question.

Any news on this? I do have the same problem here. Will this issue be fixed in the near future?

I made a patch only to add scrollbars if necessary and submitted the issue to core list for approval.

I will remove assignment to me. I do not want this bug to stay on me indefinitely.

this problem can be fixed in most cases by TS like this
tt_content.image.20.1.imageLinkWrap.bodyTag = <style type="text/css">html{overflow-x: hidden;overflow-y: auto;}</style><body style="margin:0; background:#fff;">
tt_content.textpic.20.1.imageLinkWrap.bodyTag < tt_content.image.20.1.imageLinkWrap.bodyTag

As this report is very old, is the handling in newer TYPO3 CMS Versions (like 6.0/6.1) more like you expect it?
