TreeView problem

• Best way to trigger the update of TreeItem?

  I have a TreeView which consists of thumbnails - those responsible at the request and in the meantime, just text is displayed.
  
  I however have TreeView problems to recognize when such an element is updated. Initially I tried this, calling setValue on the TreeItem element that is appropriate:
  

           private void updateItem(MediaItem item) {
        TreeItem<MediaItem> foundItem = findMediaItem(treeRoot, item);
        
        if(foundItem != null) {
          foundItem.setValue(item);
        }
      }
  
      private TreeItem<MediaItem> findMediaItem(TreeItem<MediaItem> treeRoot, MediaItem mediaItem) {
        for(TreeItem<MediaItem> treeItem : treeRoot.getChildren()) {
          if(treeItem.getValue().equals(mediaItem)) {
            return treeItem;
          }
          
          if(!treeItem.isLeaf()) {
            TreeItem<MediaItem> foundItem = findMediaItem(treeItem, mediaItem);
            
            if(foundItem != null) {
              return foundItem;
            }
          }
        }
        
        return null;
      }

  Unfortunately, I couldn't get this to work at all. After a few more tries, I found a way that works, but it is very heavy:

   private void updateItem(MediaItem item) {
        TreeItem<MediaItem> foundItem = findMediaItem(treeRoot, item);
        
        if(foundItem != null) {
          int index = foundItem.getParent().getChildren().indexOf(foundItem);
          
          foundItem.getParent().getChildren().set(index, new TreeItem<MediaItem>(item));
  //        foundItem.setValue(item);
        }
      }

  Having to create a new object TreeItem and looking for the index of the former just if I can replace it in the ObservableList of its parent seem exaggerated. I was more looking for a method simple "updateTreeItem" or something, where I can move to the item that has been updated. The API TreeCell doesn't seem to have this method, but I donot see how I can use it.
  
  Note: the element 'nine', I update here is actually the same instance (in other words, it is equal to the previous one) - I want to only trigger a new drawing, her look has changed even if it is always equal. I have not tried the substitution of equals for her, but even if it works it would be unsatisfactory because, from an application perspective, these two items are equal apart from having a miniature finished loading...
  
  A simpler solution?

• Project link error: Undefined cadquã with TreeView macros

  Hello world

  I am facing a problem of "Link error - Undefined simbol project" with TreeView, TreeView_GetCheckState() and TreeView_GetCheckState() macros that I use in my project. When I compiled in 2009 it worked, but now that I have compiled for an update later in 2010, it does not work.

  Info on these macros in https://msdn.microsoft.com/en-us/library/windows/desktop/bb773810(v=vs.85).aspx

  These macros are supposed to be set in ComCtl32.lib. I think that since this is a WINAPI it is automatically included in the project, but I have this compilation error. I have included in my project by hand and I can see it now in my project tree, but the same error persists. I have the #include commctrl.h.

  Does anyone know what I am doing wrong that my project does not have these features?

  Hi again,

  I discovered that this macros are defined in CommCtrl.h and they are dependent on the _WIN32_IE, so I wrote in the /D_WIN32_IE of compiler options sets = 0 x 0500 and now the compiler take these macros into account and, therefore, the problem disappeared. For some reason, the value of _WIN32_IE isn't the same thing in my CVI2009 and CVI2010 compiler...

  #if (_WIN32_IE > = 0 x 0500)
  tvm_? etitemstate uses only the State and stateMask mask.
  Unicode or ansi is therefore irrelevant.
  #define TreeView_SetItemState (hwndTV, hti, data, _mask).
  {_Ms_TVi structure TVITEM; \}
  _ms_TVi.mask = TVIF_STATE; \
  _ms_TVi.hItem = (hti); \
  _ms_TVi.stateMask = (_mask); \
  _ms_TVi.State = (data); \
  SNDMSG ((hwndTV), TVM_SETITEM, 0, (LPARAM,)(TV_ITEM *) & _ms_TVi); \
  }

  #define TreeView_SetCheckState (hwndTV, hti, fCheck).
  TreeView_SetItemState (hwndTV, hti, INDEXTOSTATEIMAGEMASK ((fCheck)? 2:1), TVIS_STATEIMAGEMASK)

  #define TVM_GETITEMSTATE (+ 39 TV_FIRST)
  #define TreeView_GetItemState (hwndTV, hti, mask).
  (UINT) SNDMSG ((hwndTV), TVM_GETITEMSTATE, (WPARAM) (hti), (LPARAM) (mask))

  #define TreeView_GetCheckState (hwndTV, hti).
  ((((UINT) (SNDMSG ((hwndTV), TVM_GETITEMSTATE, (WPARAM) (hti), TVIS_STATEIMAGEMASK))) > 12) - 1).

  Problem: Email opens the Inbox, but I can no longer spend JUNKbox, SENTbox, DELETEbox, since the LH side with these options disappeared.

  Go to view | Layout and enable the bar of folder or the folder list, and then you can see the other folders in the Treeview control.

• TreeView with icons displayed incorrectly after expansion (8 JavaFX)

  I have a TreeView with classes CellFactory and TreeCell custom, which has been implemented in JavaFX 2.2 and works perfectly. However, after I upgraded to 8 JavaFX. This tree is completely messed up. If I develop a nodes, there will be duplicate tree nodes in the tree. Here is a simplified version of the source code. If not use a method setGraphic() in class TreeCell, it works fine.

  package test;
  
  
  import javafx.application.Application;
  import javafx.scene.Scene;
  import javafx.scene.control.TreeCell;
  import javafx.scene.control.TreeItem;
  import javafx.scene.control.TreeView;
  import javafx.scene.image.Image;
  import javafx.scene.image.ImageView;
  import javafx.scene.layout.BorderPane;
  import javafx.stage.Stage;
  import javafx.util.Callback;
  
  
  public class TreeViewTest extends Application {
      private static final Image image = new Image(TreeViewTest.class.getResourceAsStream("icon_datasource.png"));
      
      public TreeViewTest() {
      }
  
  
      @Override
      public void start(Stage primaryStage) {
          BorderPane rootPane = new BorderPane();
  
  
          TreeItem<String> root = new TreeItem<String>("Root");
          
          for (int i = 0; i < 5; i++) {
              TreeItem<String> ds = new TreeItem<String>("Datasource " + i);
              
              for (int t = 0; t < 5; t++) {
          TreeItem<String> tb = new TreeItem<String>("Table " + t);
          ds.getChildren().add(tb);
              }
              
              root.getChildren().add(ds);
          }
          
          TreeView<String> tree = new TreeView<String>();
          tree.setCellFactory(new Callback<TreeView<String>, TreeCell<String>>() {
       
       public TreeCell<String> call(TreeView<String> param) {
    return new TreeCell<String>() {
       @Override
       protected void updateItem(String item, boolean empty) {
           super.updateItem(item, empty);
           
           if (!empty) {
               ImageView imageView = new ImageView(image);
               setText(item);
               setGraphic(imageView);
           }
       }
    };
       }
    });
          tree.setRoot(root);
          tree.setShowRoot(false);
          
          rootPane.setLeft(tree);
          
          Scene scene = new Scene(rootPane, 1024, 800);
  
  
          primaryStage.setTitle("Test");
          primaryStage.setScene(scene);
          primaryStage.show();
      }
      
      public static void main(String[] args) {
          launch(args);
      }
  }
  

  In general, cells are reused as items in TreeView (and some make, and ListViews) as soon as they become visible and invisible. It is perfectly possible for a cell to have an element that is not empty and then it change to empty, as the cell is reused for an empty cell.

  If you have a bug in your code: you need

  tree.setCellFactory(new Callback, TreeCell>() {
  
              public TreeCell call(TreeView param) {
                  return new TreeCell() {
                      @Override
                      protected void updateItem(String item, boolean empty) {
                          super.updateItem(item, empty);
  
                          if (!empty) {
                              ImageView imageView = new ImageView(image);
                              setText(item);
                              setGraphic(imageView);
                          } else {
                              setText(null);
                              setGraphic(null);
                          }
                      }
                  };
              }
          });
  

  You lucky in JavaFX2.2 that the re-use of cell does not seem to affect your bug. improving the effectiveness of the re-use of the cell in JavaFX 8 has exposed the problem.

  Furthermore, it is generally a bit pointless to re - create the nodes each time than updateItem (...) is called (frequently), rather than create them once when the cell is created (much less often). So consider

  tree.setCellFactory(new Callback, TreeCell>() {
  
              public TreeCell call(TreeView param) {
                  return new TreeCell() {
                      private ImageView imageView = new ImageView(image);
                      @Override
                      protected void updateItem(String item, boolean empty) {
                          super.updateItem(item, empty);
  
                          if (!empty) {
                              setText(item);
                              setGraphic(imageView);
                          } else {
                              setText(null);
                              setGraphic(null);
                          }
                      }
                  };
              }
          });

• unsupported TreeView Widget

  Hello

  I created a script for photoshop cc2014 it uses a tree view to display the layers in the document, and when I've upgraded to photoshop cc2015, I get the message: "TreeView is not supported" instead of TreeView. Is it possible to fix this?

  Thank you.

  Not immediately. They still use the problems with the new format of Mondo. I'll pass this message Forum script, to see if anyone has more information.

• Drag in TreeView

  Hi all

  I want to make a simple request where you have a tree and on the other side three pictures. In this example I used three rectangles each with a different color.

  The user should be able to drag one of the rectangles of an item in the tree in order to add a new paragraph.

  Everything works, the only problem I have is that I also can drop off anywhere in the entire tree 'frame '. I want that the user must release on

  an element in the tree, not anywhere in the treeframe.

  My second question is, can I also drag the entire image / rectangle instead of the standard small window box when a user tries to drag something? I read that

  in JavaFX 8 would be possible, here you are able to transmit an entire image to the dragboard. My goal was to set the opacity of the rectangle enjoy 20% and then paste

  the rectangle with the mouse, and if the user releases the mouse, the rectangle must return to its position of moose with full opacity. It would be a "nice to have", but

  the first problem is unimportant.

  This example should work out of the box:

  Everything works, the only problem I have is that I also can drop off anywhere in the entire tree 'frame '. I want that the user must release on

  an element in the tree, not anywhere in the treeframe.

  Just surround the code in methods of grip for your setOnDragOver and setOnDragDropped event handlers with

  If (! treeCell.isEmpty ()) {...}

  You could add more sense here if you need, for example to prevent the user from falling on the root or to limit the number of children has fallen on a single node.

  For the JavaFX 8 image features with stretching, in your setOnDragDetected Manager, change the opacity, create an image of the control by calling snapshot() and pass the image to the setDragView (...) method of the Dragboard. In the setOnDragDone Manager, resume the opacity.

• Icons in TreeView disappear after editing

  I have a weird bug where the graphic a TreeCell node is not displayed.

  Java version "1.7.0_25", Windows 7 Ultimate.

  The bug is not always reproducible. There are several housing starts of the application manifest.

  Example 13-3 'implementation a Cell Factory' of http://docs.oracle.com/javafx/2/ui_controls/tree-view.htm and

  Change the line

  TreeItem < String > empLeaf = new TreeItem < String > (employee.getName ());

  TO

  TreeItem < String > empLeaf = new TreeItem < String > (employee.getName (), new (depIcon) ImageView);

  for the nodes of the tree editable with icons. If we change the name of a node and attempts to change once again, but undoes the change

  -by selecting another cell with the mouse - icon of the affected node will become empty. See the image.

  I havemage

  If you put a println statement in the method the TreeCell cancelEdit(), you see, there are more alive than expected TreeCells.

• TableView problem of automatic update in points 2.1 and 2.2

  Hi, guys!
  
  Initial situation: I have a TableView with some elements inside. I update an element (a user object), I remove it from the table and then I put it again to the same index.
  
  The labour code in 2.0.2:

  // Gets selected item
  User selectedUser = (User) table.getSelectionModel().getSelectedItem();
  
  // Updates the User object to show the new data in the table
  selectedUser.setFirstName(fNameTF.getText());
  selectedUser.setLastName(lNameTF.getText());
  selectedUser.setRank((String) (rankCB.getSelectionModel().getSelectedItem()));
  selectedUser.setPassword(passTF.getText());
  
  // Updates table data.
  // First gets the user Object index in the items list,
  // then removes the user object from the table list,
  // then adds the updated user object at the same index it was before.
  int userObjectIndexInItemsList = table.getItems().indexOf(selectedUser);
  table.getItems().remove(table.getItems().indexOf(selectedUser));
  table.getItems().add(userObjectIndexInItemsList, selectedUser);

  Here's my problem: in the version 2.1 and 2.2 (b06) this no longer works. The table does not display the changed data. I also tried getTableItems tableData (new FXCollections.observableArrayList ()), then table.setItems (null), then table.setItems (tableData), but it did not work.
  So, the problem is that the FXCollections.observableArrayList () (which has been used to fill the table in the beginning) don't relate more to the table when a change is made.
  
  Possible, but not desired collaborative:
  1. total re-creation of the table.
  2. total recreation of the tableItems (create a new observable by new objects).
  
  Any suggestions?
  I don't want to recreate the table data whenever a change is made, in particular because it is based on a database.

  JavaFX has a fundamentally different way of handling these types of updates, which can make it difficult to implement this in your current system.

  In short, how updates work in JavaFX of the ListView, TreeView, and TableView is the following:

  Each view type is made of cells. The number of cells is usually pretty close to the amount of visible lines and each cell could be considered to represent a line.

  Each cell is basically a small piece of the user interface that adapts to everything that should appear on the line given at that time there. The updateItem method is called on these cells to associate them with an underlying element of the ObservableList (the model).

  Let's say that your "Items" in the model are objects with a person's name. An implementation of the cell could make this as follows:

    private static final class PersonTableCell extends TableCell {
  
      @Override
      protected void updateItem(final Person person, boolean empty) {
        super.updateItem(mediaNode, empty);
  
        if(!empty) {
          setText(person.getTitle());
        }
      }
    }
  

  The example above will also have the same problem to update your code, otherwise, if you change the subject Person in your model of the cell will not reflect the name changed.

  In JavaFX to inform the cell of the modification, you must add a listener to the property 'text' of your person object. This assumes that a Person object properties are the properties of style of JavaFX. This is done like this (using a binding that uses an internal auditor):

    private static final class PersonTableCell extends TableCell {
  
      @Override
      protected void updateItem(final Person person, boolean empty) {
        super.updateItem(mediaNode, empty);
  
        textProperty().unbind();
  
        if(!empty) {
          textProperty().bind(person.titleProperty());
        }
      }
    }
  

  The foregoing will automatically updated correctly each change to the title property of the person.

  However, this means that you need to change your Person object to use the JavaFX style properties. You donot have always this luxury hotel. However, there are other options. You could for example only support a "changedProperty" in the Person class and have cells listening to it, something like this:

    private static final class PersonTableCell extends TableCell {
      private Person oldPerson;
      private InvalidationListener listener;
  
      @Override
      protected void updateItem(final Person person, boolean empty) {
        super.updateItem(mediaNode, empty);
  
        if(oldPerson != null) {
          oldPerson.removeListener(listener);
          oldPerson = null;
        }
  
        if(!empty) {
          listener = new InvalidatonListener() {
            public void invalidated(Observable o) {
               setText(person.getTitle());
            }
          };
          person.addListener(listener);
          setText(person.getTitle());
        }
      }
    }
  

  Now whenever you want to trigger a "change", you call a method on the Person object that triggers a cancel event. All cells that are tuned to this person object will be notified and update.

  If you donot change the class of the person itself, you could also do this with a wrapper. You will have to experiment a little.

• ScriptUI: Are there ways to mimic a treeview node doubleclick?

  Hello!

  Is there a way to emulate a double click on a node in a Treeview ScriptUI?

  I don't find any appropriate on the Treeview control or Listitem (node) objects.

  Are there workarounds for this?

  Just thinking out loud:

  A Listitem (node) would be located in the coordinates of the mouse move event?

  Is it possible to put other objects as ListItems in the treeview - on top of the active list in the TreeView.onChange event item - just to get a better set of events?

  Other means...?

  Best regards

  Andreas

  Andreas,

  Nodes can be used to double click with no problems. I.e., you check if the tree was double click, then you check what in trees has been clicked. Something like this:

  myTree.onDoubleClick = doSomething;
  
  function doSomething{
     if (/*some valid selection*/){
        . . .
        . . .
     }
  }
  

  Location of an item in the list of the coordinates of a mouse event move would be very difficult, I guess.

• TreeView does not display in Bridge CS6 but it does in ESTK

  running Bridge CS6 on Windows 7.

  Well I have tried many script .jsx existing first, I reduced my test case to this code typed into the ESTK with ExtendScript Toolkit CS6 targets, bridge CS5.1 (4.1), Bridge CS6 (5.032) and Bridge CS6 (64-bit) (5.064).

  var l = new Window ('dialog');

  var tv = w.add ('treeview', undefined);

  TV. Add ('node', 'root');

  w.Show ();

  It works fine with ESTK and CS5.1 targets.

  On both CS6 targets, the window opens, but the treeview widget is empty.  This is the same behavior I saw running the SnpXMLTreeView.jsx and scriptui examples - 2.0.pdf.

  On more complex scripts (existing), it will crash or locking of the CS6 Bridge.

  

  

  A search on the web and the forums shows that I'm not the only one with this problem.

  Yes, there are many problems with Bridge CS6 scripts, but the bridge team did not always recognize their...

  For example...

  http://feedback.Photoshop.com/photoshop_family/topics/extendscript_ui_not_drawing_correctl y_in_bridge? utm_content = topic_link & utm_medium = email & utm_source = reply_notification

  It would be nice to get an update to correct these problems.

• TreeView: Line white between the two nodes are not appear

  Hi all

  I added a treeview control in my dialog plugin for InDesign CS3 and CS4.

  In CS4, it works fine but in CS3, I get a strange question.

  Question: A blank line between two nodes may not appear. See the image below

  I am referring to the white line which we can see in the InDesign paragraph style palette / all indesign sample as the Board treeview as shown below

  I tried this problem but has not found a solution

  Please help me solve this problem.

  Kind regards

  Alam

  I had a similar problem, but in the end, I couldn't figure how to remove the white lines.

  I have given up trying to remove the white and just changed the color of the treeview and everything that was drawn on the top in white.

  It was the only way I managed to hide lines.

• Fill a JQuery Treeview using a PL/SQL procedure

  Hello
  
  We have a lot of problems with the original apex trees, we decided to build our own tree using jQuery Treeview Plugin.
  We want to fill the tree by running an application process of OnDemand, which would return the HTML hierarchy like:
  

  <ul id="browser" class="filetree">
   <li><span class="folder">Folder 1</span>
    <ul>
     <li><span class="file">Item 1.1</span></li>
    </ul>
   </li>
   <li><span class="folder">Folder 2</span>
    <ul>
     <li><span class="folder">Subfolder 2.1</span>
      <ul id="folder21">
       <li><span class="file">File 2.1.1</span></li>
       <li><span class="file">File 2.1.2</span></li>
      </ul>
     </li>
     <li><span class="file">File 2.2</span></li>
    </ul>
   </li>
  </ul>

  I started coding the ODP:
  

  DECLARE    
  
  CURSOR cur IS
  select 
    op_descript, 
    op_id, 
    op_parent_op_id, 
    level
  from operations
  connect by prior op_id = op_parent_op_id
  start with op_id = 0;    
  
  BEGIN
       htp.p('<ul id="browser" class="filetree">');
       FOR c IN cur LOOP
            /* etc... */
       end loop;
  END;

  As the contents of the loop seems a bit complicated, and I don't want to reinvent the wheel, I ask you if you think of another way to fill the tree, or if one of you have already tried a similar thing.
  
  Thank you!
  
  Yann.

  Hi Yann,

  I took a glance at the jquery treeview plugin. Please forget my first comment, it does not work with this treeview.

  What you need to do is create the HTML Structure, and then call the Plugin that converts the list unordered HTML in a Treeview control.

  To create the HTML Code, I would suggest a "PL/SQL" Page of Type region

  Example:

  BEGIN
      FOR rTREE IN
        ( SELECT COL1
                , COL2
                , ...
        )
      LOOP
          HTP.PRN('
  '||....);
      END LOOP;
  END;
  

  You see? Just use HTP. PRN to write the HTML Code of a region of PL/SQL.

  brgds,
  Peter
