RTL’g Sakai Tools

In order to create a skin for a RTL context we will be working in a the tool.css (so that we can override tool_base.css) of a new skin, named RTL. We will identify changes that need to be made, workarounds, failures to account for an RTL context in the tool design, etc.

If you are not very interested in the details  – the uncombed and disreputable skin is availiable here

If you want to know how we got to this and the shortcomings of this approach, read on.

We will begin with a simple tool view  – the Announcements list. What it looks like in a LTR context:

What the direction:rtl applied to .portletBody gets us. Am keeping the language as English.

Some nice things: the toolbar has been rearranged. The columns of the announcement table have been flipped correctly. Block elements are now flush right, such as the <h3>Announcements</h3>. The label of the view navigator select is not to the right of the select. The select itself is reoriented. The list paged lists, from right to left: “first page, previous page, next page, last page” correctly as the entire block has been flipped.

Some things that will need to be addressed: a) the pipes between the toolbar items look wacky and need to be aligned right; 2) the navigation panels need to be flipped ( a sad irony: if the layout of these and the toolbar  had been a table our work would be done); 3) the text direction of the cells inside the table needs to be adjusted.

The toolbar

Align the toolbar right. We will be working in the new rtl/tool.css):

.navIntraTool {
	text-align: right;
}

Add a border to the span child of the first list element:

}
/*special style for the first item, namely no border-left*/
.navIntraTool li.firstToolBarItem span{
	/*border:none;*/border-left:1px solid #ccc;
}

and take the border away from the last:

.navIntraTool li:last-child span{
	border:none
}

Since the design of the toolbar did not take into account a RTL possibility we had to resort to a pseudo class to identify the last element. We will see this problem elsewhere.

The navigation panels

The layout of these is set in tool_base.css. We will override in rtl/tool.css:

.viewNav{
	float: right;
}
.listNav{
	float: left;
}

The table list

/*skinned header of standard tab. data table*/
.listHier th, .listHier td{
	text-align: right !important;
}

The !important is needed to override the !important in tool_base.css – a bad decision that now needs to be dealt with.

The end result:

And in the target language:

Some issues remain with the navigation panels – reversing the floats did not exactly reverse the position, resulting in some inexplicable whitespace.  Someone help, please.

To recapitulate before we take on a more complex view of this tool: a) any series that identifies a first item also needs to identify the last; b) floats are not always totally reversible.

Forms and inputs

Some problems regarding the layout of the input, label and required marker troika. The orientation of the three is just not working due to floats. An example from create a new announcement.

So we rearrange the floats and display attributes, paddings, margins (if you are redoing an existing skin, look for some of these definitions elsewhere in the sheets if your results do not match):

.shorttext label{
	float:none;
	display:block;
	padding:0;
	margin:0;
}
.shorttext .reqStar{
	float:right;
	margin-right:-7px;
}
.longtext label{
	float:none;
	display:block
}
.longtext label .reqStar{
	float:right;
	margin-right:-7px;
}

So:

And in Arabic:

The other input types render correctly without any tweaking (this is also from create a new announcement):

While on the subject of inputs, the following is also needed if there is to be mixed RTL and LTR content:

input, textarea{
	unicode-bidi: override;
}
This opens an  additional level of embedding and overrides the Unicode character ordering, reordering the sequence to the value of the direction property. 

A quick glance over the core tools and it seems most rendering now is OK. There will be exceptions where the developer has been forced to apply sui generis layout or styles because of the paucity of the default styles. There will also need to be addressed – please leave some comments where that is the case, thanks!

Off hand – here are some locales that need more work because of these and other reasons:

  1. Filtering controls in Schedule list view.
  2. “Add” menu in Resources – text is misaligned.
  3. Certain icons are facing in the wrong direction – such as disclosure triangles. These will need to be replaced in the file system when they are inline images, or in the skin when pulled as background images.
  4. The FCK Editor – needs configuration – information on configuring the FCK Editor for RTL is here. There are language files for Arabic and Hebrew, Persian as well. Probably a lot of other stuff that a native speaker could figure out needs to be tweaked.
  5. Placement of icons inside certain blocks needs to be tweaked – see alertMessage etc. 

The uncombed and disreputable skin is avaliable here.
