• App stop non destructive outbreak of class?

  Is it just me or BB10 does NO destroyers, including your main application class, when it stops your application with the X button? This means not only that no cleaning is done by the main application class, but also by children of the app's classes.

  I know I can do cleaning, managers of manualExit and aboutToQuit signals, but what's the point of instantiation of classes with (this) .parent if their destructors are never going to call anyway?

  I tried the breakpoints of parameters in my destructive code, and they called when I delete the objects programmatically, but never during the shutdown of the application.

  Good catch, although not quite because the app is on the job. I created a new empty application with Momentics, and it looked like this:

  Q_DECL_EXPORT int main( int argc, char **argv ) {
      // this is where the server is started etc
      Application app( argc, argv );
  
      // localization support
      QTranslator translator;
      QString locale_string = QLocale().name();
      QString filename = QString( "BlankTest_%1" ).arg( locale_string );
      if ( translator.load( filename, "app/native/qm" ) ) {
          app.installTranslator( &translator );
      }
  
      // create the application pane object to init UI etc.
      new ApplicationUI( &app );
  
      // we complete the transaction started in the app constructor and start the client event loop here
      return Application::exec();
      // when loop is exited the Application deletes the scene which deletes all its children (per qt rules for children)
  }
  

  .. .the class ApplicationUI is created, but it is never deleted. I guess it's been abandoned once main() ends by garbage collection. I tried to change it to this:

  Q_DECL_EXPORT int main( int argc, char **argv ) {
      int retVal;
      ApplicationUI* ui;
  
      // this is where the server is started etc
      Application app( argc, argv );
  
      // localization support
      QTranslator translator;
      QString locale_string = QLocale().name();
      QString filename = QString( "BlankTest_%1" ).arg( locale_string );
      if ( translator.load( filename, "app/native/qm" ) ) {
          app.installTranslator( &translator );
      }
  
      // create the application pane object to init UI etc.
      ui = new ApplicationUI( &app );
  
      // we complete the transaction started in the app constructor and start the client event loop here
      retVal = Application::exec();
      // when loop is exited the Application deletes the scene which deletes all its children (per qt rules for children)
  
      delete ui;
  
      return retVal;
  }
  

  .. .and now the destructor of ApplicationUI fires before leaving the main().

• objects vs C++ QML Dynamics

  normally I use ComponentDefinitions and create / destroy all my UI of QML, who works fast and easy.

  C++ only I use for business logic

  Sometimes I have to create a C++ user interface controls, in this case a sheet, because:

  If you use a spreadsheet with a NavigationPane or TabbedPane a TabbedPane root tab,

  then c++ findChild can not find 'behind' the leaf objects

  See this thread.

  so my solution is to create / destroy these leaves of C++, because then I can ask these leaves to find objects.

  It works perfectly and I will write blog and provide video HowTo handle this

  Now my questions to all the C++ / Qt gurus out there:

  What is the best way to create / destroy the leaf?

  Here is my code:

  1. open the sheet

  called from QML

  Create the spreadsheet and open it

  void ApplicationUI::openAdminSheet() {
      QmlDocument *qmlAdminSheet = QmlDocument::create(
              "asset:///admin/AdminSheet.qml");
      qmlAdminSheet->setContextProperty("REST", mKinveyREST);
      qmlAdminSheet->setContextProperty("sercar10", this);
      mAdminSheet = qmlAdminSheet->createRootObject();
      mAdminSheet->setParent(this);
      mAdminSheet->open();
  }
  

  everything works perfectly

  Sheet with TabbedPane opens on top

  I put setContextProperty of classes where I invoke methods.

  my business logic found objects such as DataModels, etc. drop-down menus using findChild() sheet as root

  When the work is done and user wants to go back:

  2. close the sheet

  called from QML

  close the worksheet

  destroy the roadmap

  call a function in QML. This function lives in the part of the root, so not executable from inside the leaf, but the roots after the closure of the leaf

  void ApplicationUI::closeAdminSheet() {
      mAdminSheet->close();
      mAdminSheet->deleteLater();
      QMetaObject::invokeMethod(Application::instance()->scene(),
                  "goHomeFromAdmin");
  }
  

  -------------

  now my question:

  I use deleteLater() to destroy the roadmap.

  is it ok?

  This means content will be deleted without danger?

  is this the right place?

  or should I only do the close() and connect to onClosed() Signal and then deleteLater?

  What happens if the user closes and opens very fast sheet and openAdminSheet() creates a new worksheet before execution of deleteLater()?

  Could it happen?

  THX for tips HowTo, go the safer way to create / remove sheets of C++ - even if the user clicks repeatedly on open / close?

  Hello

  1. open the sheet

  QmlDocument belongs to the default application. Where it is used to instantiate a single page, this page can be defined as the mother of QmlDocument, so they are destroyed together (this technique is described on this page).

  ...mAdminSheet = qmlAdminSheet->createRootObject();qmlAdminSheet->setParent(mAdminSheet);...
  

  Loading of the QML will take probably some time, perhaps that is useful to load the document once and store it somewhere, spawning objects if necessary root while reusing the QML. While it should work in theory, I have not tried this.

  2 destruction of the leaf

  Close() is not instantaneous. deleteLater() is asynchronous, but most likely will trigger before close animation is over, so I think it's safer to wait until closed() is triggered and destroy the paper after that. This can be done on the spot, something like:

  QObject::connect(mAdminSheet, SIGNAL(closed()), mAdminSheet, SLOT(deleteLater()));
  

  children of mAdminSheet should be removed safely if their parents are properly defined.

  > what happens if the user closes and opens the sheet very fast and openAdminSheet() create a new worksheet before deleteLater() run? Could it happen?

  mAdminSheet is only a pointer (a memory address). The real object is not destroyed even if the pointer is overwritten.

  After

  mAdminSheet->deleteLater();
  

  is called, it is prudent to reassing pointer in openAdminSheet. The old object will continue to exist until it is removed from the queue of events in Qt.

• Knife will not divide an object

  I have imported a png file and can not divide the different images in the file out of the other.  I tried the knife tool, the pathfinder tool, all without success. I wonder if I first change the file itself.  I like to shoot the green image in a separate object.  Thank you in advance.

  

  Sam,

  Illy (description of work Adobe Illustrator) sees just like clusters of pixels of raster images.

  And each image is just a bunch of pixels, regardless of how things look.

  You can cut the picture by cropping in Photoshop (get a copy of the image around the green part) and another around the red part.

  Or you can let Illy do it in a corresponding manner with the dirty destructive work done on two copies:

  (1) create a path where you want to crop the image (including the relevant part);

  (2) select the two path and image and Ctrl + 7 (object > clipping mask > make);

  (3) in the drop-down list the palette/Panel transparency list select everything except Normal (Multiply is fine; this step may not be necessary in your version, you can try without him).

  (4) object > flatten transparency, just keep the defaults including 100% vector.

  (5) thrill (optional, unless that inevitable).

  This will crop the image to the (the bounding box of the) Clipping Path.

  Other, and mentioned tools only work on traces objects.

• Could not complete your request because the smart object is not directly editable

  Well, I'm trying to simply remove a background but photoshop won't let me do. It comes up with the error:

  Could not complete your request because the smart object is not directly editable

  I read on the internet, saying that I should "rastize" my diaper. I googled rastize, but I couldn't find a good answer is that rastize. Also, I tried to translate rastize into my mother tongue, but it also says rastize. However, my photoshop is in Dutch. I couldn't find the option 'rastize '. What should I do? Here is a screenshot:

  https://postimg.org/image/enzf7mah3/

  Rasterization is to flatten just this particular layer. Since you are using is a smart object, you can double click top in the layer panel and edited directly, or you can rasterize it. It is always better to do a non-destructive editing, so you really need to use a layer mask to remove the background rather than delete it. However, the position of pixelation here is a layer in the menu:

  

• Replace the color of Rusty object

  Hello

  I have a rusty object I need green replaced with red, but without interfering or color.

  I found the color replace did a pretty bad job, creating a solid color layer and masking work, but he "painted" on the rust, the Replace Color tool is pretty good, but there is no way to adjust the color. I used a dark red-brown and it seems enough rose (see attachment).

  It would be ideal if I could exit the replacement as an adjustment layer brush, not sure it's possible...?

  

  

  

  If anyone has any tips or advice it would be greatly appreciated.

  See you soon.

  Create green color with the Magic Wand selection, click Hue/Saturation in the Panel settings then check the colorize and play with hue, Saturation, and brightness sliders. You can change the mask later using the Brush tool, for example. In this way, you will have non-destructive adjustment layer and mask layer you can change at any time. You can use and other adjustments like curves but according to me, is easier with the Hue/Saturation, if you want to visually work without matching the exact values.

  On the screenshot below, I've done exactly in front of the thing by mistake, but the principle remains the same.

  I guess this feature without doubt not will be part of Lightroom because of the non-destructive nature publishing. Is that programs like Photoshop are for. But I don't speak for Adobe, because I do not work for them, and I did not all understand what are their plans for the future.

• Original destructive editing using Lightroom?

  Is there a hidden feature in Lightroom that will allow me to edit, or back up my original JPEG files, destructive?

  Normally, I would never change my own originals, but there is in the project that I am currently working about 255 JPEG images taken with an iPhone and already arranged in a video slideshow in first. However, someone didn't bother to change levels or color correct it at any time, and I do not want to completely re - build all of the video sequence. Ideally, I can just edit original and update the first with the change until I give...

  All of the intentions and objectives, levels, and color correction on the front is heavy, difficult and does not offer the finest photo, change in the characteristics of LR, this is, in my opinion.

  My other option, it seems to me, is to open and change each one individually with Photoshop and save the originals in this way, but it is slow and inefficient compared to LR to work with such a great set.

  Any help, or wrapper or plug-in work suggestions would be greatly appreciated.

  Thank you.

  Is there a hidden feature in Lightroom that will allow me to edit, or back up my original JPEG files, destructive?

  Laughing out loud!

  You could--

  1 adjust images in Lightroom

  2 export all images. (JPEG, do not resize, do re not name)

  3. Optional-(supprimer tous les originaux)

• Photoshop is completely non-destructive

  I feel that Lightroom is completely non-destructive but Photoshop isn't. Can someone please clarify this for me?

  Photoshop was made (there for many years), a publisher of pixel as such destructive in terms of basic functionality. Later they added features that make it possible to work non-destructively (most importantly the layers of adjustment and smart objects).

  Then Yes, you can easily transform a porridge with Photoshop file, but you don't have to if you do not want.

  Lightroom was made as a parametric Editor, where all the settings are written as text instructions and saved as metadata. So with Lightroom, it is not possible to change the original in some way, even if you wanted to.

  BTW, I personally think that the term "non-destructive" is somewhat a smoke screen - at least in the current context. Of course, it is never totally destructive as long as you keep the original as the background layer and do not touch that. But the real advantage with 'non-destructive' is that you can go back and readjust even once the file is saved and closed. So, I prefer to call re-editable or reversible, or something in that sense.

• DNG import a stack and align as a smart object without rasterising?

  I can't do this without rasterising. It would be a great help for my workflow. Is there a solution for this option to prevent a destructive change?

  Any help much appreciated.

  You can't do an align layers with a dynamic object - I tried. Most of the time when you make a layer to align, it is followed by a merger of the layers, which also won't work with the statement of objections, as PS does not change the tones to mix properly, so I think Adobe don't think it would be nice to have so MUCH to this effect.

• Change the color of an object with blur

  I have a group of objects, that I submit for a stock site, but as I was testing things I realized that I couldn't change the color of the blurred items that I had developed the appearance. I had expanded the appearance so that if the object has been to scale upwards or downwards, the blur would stay in proportion. How can I maintain the blur effect (trying to make the highlights and shadows mix their better circles), while being able to change the color, AND resize it while maintaining the proportions? All tips are appreciated!

  I found a solution. If someone runs into it, here's how you can resize non-destructive. You don't need to expand appearance so you can keep changing the color and appearance itself. You'll just have to resize using the tool of the scale instead of drag the handles of the object. When you use the scale tool, you can specify that you want to scale appearances.

• [Q] not destructive of the adjustments to layer masks?

  Hello.

  Is it possible to make non-destructive adjustments to a layer mask?

  Thank you very much

  Jon

  

  We can divide the mixture so manages by alt-click-drag the.

  Edit: actually, come to think of it, the dynamic object can be useless, Clipping a layer adjustment in hidden layer with mixture settings so should work.

• Mirroring with non-destructive outline

  I am trying to achieve...

  

  .. .but with appearances, so that I can always change the graphic later, to say that if I wanted to do something like this (alt + click - move to dupe an item within the Group)...

  (desired mode traced result)

  Someone knows how to do this in a non-destructive way, so that I don't have to recreate the black outline around all of this, every time I want to make a change?

  To do now:

  1. Create the two square, group them and create an appearance (fx > transform) to account for x with a copy (mirroring the object on the left side).
  2. Expand the appearance.
  3. Copy all stick behind, add the paths and add the black line.

  Makes me what I want to see, but it's a pain in the neck for edit/edit/Polish. I want to get the run around these two objects in the Group and still be able to non-destructively (i.e. do not expand appearance) change the group with update of the race and thinking. Can it be done? Without a script?

  See you soon,.

• Adjustments are disabled for dynamic objects

  I want to edit a photo of LR3 as dynamic objects. When I open it for LR3 in CS5 I can't use the adjustment tools because they are disabled (all instead of the shadows and HDR). Why?

  Because only a few of the adjustments can work as smart filters.  And because dynamic objects are not pixelated layers that can be adjusted in a destructive way.

  You should use adjustment layers.

• Develop Lightroom and raw Photoshop smart objects

  I understand the function develop that Lightroom and Photoshop raw adjustments are the same.  So I adjust in one or.  I can then open the image as a smart object in photoshop. I can then perform other settings as an adjustment layer. I think it's the same as a function to develop Lightroom and Photoshop raw adjustments?  I understand the dynamic objects allows to edit not destructive and dynamic filters.

  SO my questions are: when you would not open the image as a smart object? Surely that I should always open the image as a smart object?  If I want to make objects not allowed to smart edition as Clone Stamp I can then create a new layer and then apply the Clone Stamp to the layer, I can't?

  Then, should I also convert all layers to smart layers or leave them as a normal layer.

  Or third, I'm away from the track?

  Check that the size of the file of this image saved under Camera Raw smart object... make sure that you ALWAYS want to use THE? Hope you have big hard disks...

  Camera Raw Smart Objects are indeed useful especially when you want to melt renderings ACR 2 or more in a single file. But Smart Objects are a lot more limited than files regular pixel. Use them when it makes sense...
