Update of popup when the export dialog box is open

I am writing an export plugin to export images on my Web page. On the export dialog box, a drop-down menu to select the gallery where the image should I exported. Contextual menu items are read by the web server after the login information is validated, this product only when I update my login information.

I wonder if there is no way to update the list at the opening of the export dialog box? Add a LrHttp.get call to the startDialog method an output error occurs.

How can manage us such smart update function dynamically export gui?

Best,

Marcus

You could link the 'items' of the popup_menu property to a key in the property table.  Then have an asynchronous task is the LrHttp.get () and update the value of this key.  In broad terms:

f: popup_menu {points = LrView.bind ("menuItems")...}

LrTasks.startAsyncTask (function)

... LrHttp.get ()...

prop.menuItems =... get() property...

  • Overview of the output only works when the preview dialog box is open?

    The preview of the output adjustment certainly between into force, but only when the output preview dialog box is open, while precisely the preview of the images in playback mode is not possible; It is only possible to preview by clicking on an image and open the dialog of OP. As soon as the OP dialog box is closed, the image reverts to its prior Preview State. This is not normal!

    That's how it has always been. Keep in mind, this is a modeless dialog box, it prevents you to navigate through the file.

  • Sharpen in the develop module or in the export dialog box?

    Interpreted by using LR, "output sharpening is in addition to any sharpening you apply in the develop module.» So, I wonder, if do sharpen in the develop module (which is usually the case, because I ask to sharpen when importing as a preset) should still possible sharpening on export (Export, dialog-> output sharpening)? My workflow is usually as follows: 12 mp raws of import, with a "Preset" involving some sharpening (55,1,40,0), then make some adjustments for the photos and I export to jpg with a heavy (long edge 800pix) resize. Export I usually check "sharpen to: screen" "amount: standard." This is my workflow sharpening OK?

    Thank you.

    Yes. Sharpening in two different points. Sharpening during sharpening - develop entered to correct the softness introduced during of conversion of camera detector and later Demosaic process. It's the sharpness that you can easily see the edges more than giving contrast to full view.

    Output sharpening is dependent on the display of the output (in general, print or screen) and is a different animal.

    There are a lot of references inthese communications forums and debates on the differences and the reasoning and the math behind how to Lr.

  • When a modal dialog box is open, and you click anywhere else, there are much too many blinks of this window

    What settings can I change the number of flashes of the modal window

    It is currently set to 6 so it seems and with the software, that I work with is quite disturbing.

    For example, to open the Panel of-> region and language-> additional settings

    A new window should open to the right and down and on top of your active window.

    Is it happens click on the previous window (behind the one that just opened), you should see the window flashes 6 times.

    How can I change something like: say 3?

    Thank you

    After you have backed up your registry database (in case something goes wrong) please see Windows 7 / 8 stop dialogue modal flash Focus parent. If you find that more useful, use a value of 3 instead of 1.

  • Helps the modal dialog box a value back to the calling page

    Greetings,

    Apex Version: 4.1.0.0.32


    What I'm trying to do is create a modal dialogue that is called from a form page. The user dialog box will report to IR which allow him to select a line and send a value of this line to a field of the calling page. I work in Firefox, but I get an error using IE 8. I hope that someone can show me why it does not work in Internet Explorer.

    Here's how I do it:

    Of the calling page:

    Created a button
    Action: Redirect URL
    Target URL: javascript:var rc = window.showModalDialog ('f? p = & APP_ID.:70: & SESSION.: & DEBUG.:', ",'resizable: Yes;) Center: Yes; dialogWidth:1000px; dialogHeight:500px ;') ;


    On the page called:

    The called page is an IR report where the query returns this as one of the columns:

    * (Note: I had to put a point '.' before the onclick so he could show in this thread.) It is not there in my actual code.) *
    select
    <a href="#" name="z" style="color:blue; text-decoration:underline;" .onclick="javascript:passBack(''' || LOT_NO ||''');">Select</a>' SelectThis
    , column1
    , column2
    from sometablename;
    This solves the anchor:
    <a .onclick="javascript:passBack('232158');"  href="#">Select</a>
    Here is the function Javascript is called the anchor onclick:
    function passBack(passVal1)
    {
      opener.document.getElementById("P75_ITEM1").value = passVal1;
      close();
    }
    When I run the present in Firefox, it works as expected. I click the button on the parent page. The modal dialog box is open and the report of the IR is displayed. I click on one of the links in the report and it returns the correct value to the appellant and closed page modal dialog box.

    When I run it in IE8, it fails. I click the button on the parent page. The modal dialog box is open and the report of the IR is displayed. I click on one of the links in the report and I get this error: 'opener.document is null or not an object ".

    I hope that it is clear and that someone can help.

    Thank you

    A quick google search determines that window.opener does not exist when you use window.showModalDialog

    Range of suggestions to use window.open instead of window.showModalDialog to use instead of window.opener dialogArguments

    Try the following:

    The parent page to define a getPopupValue() function:

     function getPopupValue(){
       var dr =  window.showModalDialog('f?p=&APP_ID.:70:&SESSION.::&DEBUG.:::','','resizable:yes;center:yes;dialogWidth:1000px;dialogHeight:500px;');
    
        if ( (dr != undefined) && (dr != '') && (dr != false) ){
         $x("P75_ITEM1").value = dr;
        }
     }
    

    Change the url of the button to call the function:

     javascript:getPopupValue(); 
    

    On the popup page change the valve function for:

    function passBack(passVal1)
    {
      returnValue = passVal1;
      close();
    }

    No idea on how to delete a version

    There is no aspect of registry of a SQL Developer installation.  Only...

    1. the folder where you install SQL Developer.  You should always unzip into an empty folder, of course.

    2. the folder which contains the parameters of the user (either the default value, initial settings or settings migrate one installs it earlier).

    For WIndows Vista & upwards, for example, the default user settings for all installations of SQL Developer are under Developer %APPDATA%\SQL.

    The %AppData%\microsoft\windows\sendto is something like C:\Users\\AppData\Roaming.  Win XP used a slightly different naming convention.  Each facility has a record for its parameters to the user of the SystemN.N.N.N.Nform.  Don't forget that AppData is one of those hidden Windows folders.

    So the current production facility will have user settings in C:\Users\\AppData\Roaming\SQL Developer\system4.1.1.19.59.

    For SQL Developer 4.0 & upward, there is also a separate C:\Users\\AppData\Roaming\sqldeveloper\...\product.conf to point to the JDK.

    It's always a good idea to export your definitions of connection for installation before nuking its SystemN.N.N.N.N folders.

    So, delete a SQL Developer installation is also simple to delete the installation directory and the directory of the user for this version parameters.

    Moreover, the Export page for 4.0.0.13.80 utility preferences (and 4.1.1.19.59 is the same) should look to...
