I'm wondering how to set the Tab Order (for accessibility purposes) in iText 7 via code. In Adobe Acrobat, I can open up Page Properties (see image) and choose the tab order. Now, iText 7 correctly loads and saves existing properties, but I can't figure out a way to actually set the property using code. Does anyone know how to do this?
Right now there is no convenient API to set tab order on a page in iText7. However, you can always do that on the PDF level using object manipulation.
Assuming you have a PdfDocument, you can access any page you want and get a PdfPage instance, and then you can set the value of the /Tabs key as in the following piece of code:
PdfPage page = pdfDoc.getPage(1);
page.put(new PdfName("Tabs"), PdfName.S);
Value of PdfName.S corresponds to structure order. Other possible values for PDF 1.7 are PdfName.C (column order) and PdfName.A (annotations array order).
Please note that now you have to create a PdfName instance for Tabs manually, but the new PdfName.Tabs will be available in 7.0.2.

I have tried everything I know to make title of header replicate items value, including substitution string &P10_TITLE_TEXT. inside headers title property. Generally, this would work for normal region, but in my case I try to modify value of pages main region, which is rendering first, before any other item. My assumption is that title text is not showing because it cannot see items value yet.
Is there a simple way to refresh title header after items are ready, or perhaps another better solution?
PS: This is main header of the modal dialog page, that has no property for setting static id, and it's template is less adjustable then normal regions.
Try the following javascript in "Execute When Page Loads" of the modal page:
$('.ui-dialog-title',parent ? parent.document : document).text( apex.items. P10_TITLE_TEXT.value );
Pre-Rendering computations may be the solution here.
You can try creating a computation before Regions under Pre-Rendering to set &P10_TITLE_TEXT.. There will be no need to "refresh". This is if you are simply loading it once.
If you are trying to set headers based on input every time you change it, I would advise separating into two pages so you can submit the page and APEX can reload and process, or just use javascript.
Is my expectation valid? If yes, please guide me.
Local machine->local server process-> I generate Birt report-> which contain hyperlinks hard coded for example: http://www.ip_one.com/birtserver/parameters...(this is fine and points to another report and get me the report also when I hit the Url from inside the generated pdf report).
Now, what I need is to change ip_one to suppose ip_two once I hit the hyperlink which is inside the pdf(on the fly) keeping all the other parts of the url intact.
I am using birt-rcp-report-designer-4_2_2.
Thanks in advance.
It sounds like you are trying to dynamically create a hyperlink at report run time.
In the properties editor of the report item that has your link (i.e. label), edit the hyperlink. In the Hypelink Options (pop-up) to the left of "Location" field is the button ab| select 'JavaScript' Syntax.
You will be able to create the URL using JavaScript.
I am trying to change the layout ( css/html structure) of Virtuemart 2 order verification emails. Problem is that I have to make a fake purchase each and every time I do a change in the 10 different files (located # components/com_virtuemart/views/invoice/order/tmpl) that create this email template.
The closest "preview" I got was this direct access url "http://domain.com/index.php?option=com_virtuemart&view=invoice&layout=invoice&format=html&tmpl=component&virtuemart_order_id=1401"
But again it loads Joomla's head/body elements not the actual email template.
So how can I have a "preview" of how the template looks like with my new changes BEFORE make an actual test purchase? Is this possible?
You shouldn't change the core files otherwise the next update of VirtueMart (of which there are many) will erase your changes.
You should use Joomla!'s template overrides which VM2 supports that way you can update as needed to new versions without loosing your changes. See this article on docs.joomla.org on "How to override the output from the Joomla! core" and this one on template overrides.
3. You need to add the &format=raw at the end of the link to retrieve just the output of the component with out the template/html body wrapped around it. Of course that relies on the component as well.
I was going to suggest using raw, but looking at the current VM2 it doesn't properly support the format=raw option. Looking at the mail layout in the invoice view it not structured to return it the way you expect, it actually generates a HTML version by default with a matching text only version.
The best I could come up given those two options
Return a close equivalent of the HTML email
http://domain.com/index.php?option=com_virtuemart&view=invoice&layout=mail&virtuemart_order_id=1401&tmpl=component
Return the text version, albeit wrapped in the html page... you may have to view the source to see your invoice text.

Im using play framework and rendering PDF usin rednerPDF() method.
I would like to display some part of content always be in new page.
For Example I have two tables, One table should be in first page and another table should in next page instead of continue from first page. The first table contents are dynamic and we can't sure the height of the table.
Is it possible?
Is it possible?Yes.
You said one table(first one) should be in first page,and again you said its content is dynamic.Now my question is it span over pages and in the next page you want to write second table?This is a generic scenario and what you mentioned is specific one.
You can start trying using two properties of PdfPTable setSplitLate() and setSplitRows()(just google it out for details read Itext In Action).Just keep Two table as two Rows of outer table.set those two property for inner as well as outer in some way as you want(i.e generic case/Specific case).
Another alternative way is use writeSelectedRows() method over PdfContentByte(I don't konw which Object you gonna use for manipulating pdf but you can get it from PdfWriter,*PdfStamper* by using getDirectContent/*UnderContent*/OverContent) after generating table.To use this method you have to set total width of the table so the height can be calculated by method getTotalHeight of PdfPTable.If You use this height properly you absolutely know where your table ends.But all these specific part you have to read & understand first.
With yahp you can use a special html tag to force a page break
<yahp:pb />
we can achieve this by page-break-after:always
Please refer

i would like to create an image gallery on my homepage in drupal. Each image will have been uploaded by the user, and, as i understand it, will be saved in some image directory folder in drupal. My question concerns a recent tip i picked up in response to the general debate whether or not it is good to store images as blob in mysql. The tip was to store the filenames of the images in mysql so you can essentially still sort the files. I was wondering whether this would be possible even if the files url is in drupal so to speak. It should be possible shouldn't it? I new to programming you see and want to the images on my homepage to be periodically refreshed according to a define sorting function. I would greatly appreciate any response to this question. Cheers.
You can using content types and views module for create gallery in Drupal 7.
First create new content type with gallery name(admin/structure/types/add).
Then add a image field to gallery content type and save it.
If you want have thumbnail of image you should create a image style. for example create a image style with thumbnail_custom name and add suitable effect(admin/config/media/image-styles/add). You will use of this image style in views in the next step.
Then create a new view with gallery-view name. uncheck create a page, check create a block, enter block title and item per page you want(admin/structure/views/add).
In Filter criteria from block details add content type gallery.
In Fields add Content image that appears in node:gallery and select and select thumbnail_custom for image style option.
Save view.
This view block appears in Blocks section and you select region for it.
If you want this block appears only in the front page, in configuration of this block in the section pages of visibility settings check "Only the listed pages" option and then enter "<front>" phrase in textarea.
