How to get the data of the photo outside processRenderedPhotos?

LR SDK is still new for me. I'm fixing some issues of a project open source. It plans to export files to Wikimedia Commons from LR. There are two places where it is necessary to fill in a text based formular by actual values of the selected photos: (a) export, (b) to the dialog box export, it is possible to get a glimpse of the form, it takes as the first photo of the selection. (b) can be called before (a).

(a) works very well. An iteration is performed, the context is available by setting calling 'exportContext' of function 'processRenderedPhotos '. "exportContext" is used to get the 'exportSession '.

(b) is caused by a push button to "viewFactory: push_button" in "sectionsForTopOfDialog". It is nor a "'exportContext ' or a 'exportSession' available. "

So far I have no idea, to get data from a photo outside of ""processRenderedPhotos ", like"sectionsForTopOfDialog". "

Thank you for your interest to this thread!

Any help is appreciated.

Another description of this problem recently, I've done here: here.

If you run these lines with a debugger, you see the following error message:

This error message is from LR to tell you that you must call the method from one task other than the main task of the plugin:

Because a large part of the SDK must be called from one task other than the main task, my plugins used to do all their work within a work started by LrTasks.

In general, when a plugin generates an error, LR will be silently to complete this task and does not display the error (which is what has happened to you).  To get the errors displayed, you must wrap the text of each task in the following:

My debugging Toolbox has syntactic sugar that makes it easier, for example

You should also encapsulate callback functions that are passed to UI elements created by LrView.

  • Photosmart 7525: photosmart 7525 photo tray - how to get the photo tray to use instead of the main tray

    I use a computer from Dell using Windows 8.1 desktop 64-bit.  Printer is HP Photosmart all-in-one 7525.  The software is Microsoft Picture Manager.   I want to print a photo .jpg of MS Picture Manager for paper photo 4 x 6 I have loaded in the photo printer paper tray.  The problem is that printing is still trying to main paper tray in the printer.  Remove all paper from the main tray just causes the print operation to not to say that the main paper tray is in the paper.    If the main tray contains plain paper, the photo printed on this paper.  I have the printer set up to use the photo tray.  I select HP 4 x 6 paper in MS Picture Manager and also set Picture Manager to the highest print quality.  But no mater what I tried, the printer selects tray to main paper rather than the smaller photo paper tray.  The printed image is 4 x 6, but it is printing on paper of the main plate.  What I am doing wrong?

    Well - I found that among the pop ups related print had a link 'options' that seems to indicate that it could be me trying to change things which were not suitable for my printer - so I didn't click the link.  So this time I didn't click the link and he showed me up - again - to set the s/w to use the photo tray.  So I did and the photo made print from the photo rather than the main tray tray.  So now I know how to do and don't need to mess with trinkets or all other signs, you've shown me.  Thank you for taking the time to try to help me.  I appreciate your help.  CR

  • Inversion of executives to 'draw' effect - how to get the photo to stay.

    Hi all

    I'm just learning how to create the "drawing" wonderful flash effect by reversing the images. However, when I publish my work (.swf either as an animated .gif) drawing is inspired, and then the completed chart disappears.

    I have the settings so that it will not loop because I don't want it "draws" more than once. So what should I do so that when the animation is made drawing, it does not disappear?

    Thank you!

    Use the IW format - it will make independent NLS solution. And all you need is truncated 7th day of each month using IW:

    select  sysdate current_date,
            trunc(trunc(sysdate,'mm') + 6,'iw') first_monday_the_month
      from  dual
    --------- ---------
    08-MAR-13 04-MAR-13

    Here is the list of the first Monday of the month of this year:

    with t as(
              select  add_months(date '2013-1-1',level-1) dt
                from  dual
                connect by level <= 12
    select  dt first_of_the_month,
            trunc(dt + 6,'iw') first_monday_the_month

    Date1 - date2 is the exact number of days is after date2 date1. (It is as accurate as possible, given that the DATEs do not have fractions of a second).

    and one entire display i mean positive integer
    Select round ((sysdate) - to_date (date_start)), date_start days of per_periods_of_service

    You want to probably get the exact number of days first, then ROUND this number:

    SELECT  ROUND (SYSDATE - TO_DATE (date_start, ...))   AS days
    FROM    per_periods_of_service; 

    Always pass arguments at least 2 to TO_DATE:
    (1) the string to be converted, and
    (2) a saying string how (1) is formatted

    This gives negative also result

    Right; If date1 is before date2 then date1 - date2 returns a negative number.
    If you want to never get a negative value, use ABS (date2 - date1). If it returns 4, then you know that one of the DATEs was 4 days before the other, but you won't know who was earlier.

    I hope that answers your question.
    If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and also publish outcomes from these data.
    Explain, using specific examples, how you get these results from these data.
    Always tell what version of Oracle you are using.
