• Is it possible to get the class of a generic Type?

  I wanted to male a generic class to map the static fields of a class, of the same type (think < tt > < /tt > Color.RED) and the only way I could find to get the class fields / was passing the literal class to the constructor. Is there a way to do this with a constructor with no arguments?

  package darrylbu.util;
  
  import java.lang.reflect.*;
  import java.util.*;
  
  public class StaticFieldMap<T> extends HashMap<String, T> {
  
    @SuppressWarnings("unchecked")
    public StaticFieldMap(Class<T> clazz) {
      Field[] fields = clazz.getDeclaredFields();
      for (Field field : fields) {
        if (field.getType() == clazz) {
          try {
            put(field.getName(), (T) field.get(null));
          } catch (IllegalArgumentException ex) {
            ex.printStackTrace();
          } catch (IllegalAccessException ex) {
            ex.printStackTrace();
          }
        }
      }
    }
  }

  Since the usual question what about the reflection is usually "why?" I am including a possible use case.

  import darrylbu.util.StaticFieldMap;
  import java.awt.Color;
  import java.util.Map;
  import javax.swing.*;
  import javax.swing.event.ListSelectionEvent;
  import javax.swing.event.ListSelectionListener;
  
  public class ColorMapDemo {
  
    public static void main(String[] args) throws Exception {
      SwingUtilities.invokeLater(new Runnable() {
  
        @Override
        public void run() {
          new ColorMapDemo().makeUI();
        }
      });
    }
  
    public void makeUI() {
      final Map<String, Color> colorMap = new StaticFieldMap<Color>(Color.class);
      String[] data = colorMap.keySet().toArray(new String[] {});
      final JPanel panel = new JPanel();
      final JList list = new JList(data);
      list.addListSelectionListener(new ListSelectionListener() {
  
        public void valueChanged(ListSelectionEvent e) {
          if (!e.getValueIsAdjusting()) {
            panel.setBackground(colorMap.get((String)list.getSelectedValue()));
          }
        }
      });
      list.setSelectedIndex(0);
      panel.add(new JScrollPane(list));
      JFrame frame = new JFrame();
      frame.add(panel);
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.setSize(300, 300);
      frame.setLocationRelativeTo(null);
      frame.setVisible(true);
    }
  }

  Thanks Ben. Sorry - what a j.l.r. type?

  A java.lang.reflect.Type all j.l.Class implements this interface. What you have to do is this.getClass () .getGenericSuperclass () of the class, the cast of the Type returned to ParameterizedType, call getActualTypeArguments() and the result would be the color class object.

  I don't really have the "requirements" being just a hobby programmer. But the other day I wrote a program to display all "named colors" of javafx.scene.paint.Color (there is a lot more than in java.awt.Color) and I felt that a utility class/method can be useful to have around.

  Well, the technique described above is somewhat fragile, but achievable. If it is 'just' for a project, you need to decide for yourself if it's the right person.

  Composition of favour over the legacy; StaticFieldMap should implement the map and delegate to an internal hash table.

  Must do it, thanks. I guess that your reasoning behind the advice is that the class is a card but is-not-a HashMap. Am I wrong?

  Correct, and the implementation details would be so leaked into your public API if it were to inherit from HashMap.

  Or do you think it would be better/cleaner to do this with a utility method?

  Yes. However, playing with the API j.l.r.Type is a good learning experience. I remember trying to use seriously and then thinking changed his mind. However there are cases where it makes sense to use [1].

• Manipulate the menu refnum

  Is it possible to manipulate the paths menu item in the same way that you can manipulate the paths?  With the files, you can build paths and trails band will get where you want to go, but I don't see any way to do with menus.

  I have an application that dynamically generates the menus.  When a user selects a menu item, I want to give him a check, but I want to uncheck all the other menu items that are in the same submenu.  If the menu items are fixed, it's not a problem, but if the menu items are dynamic, I'm having a devil of a time.

  I solved my problem.  I had a typo in very stupid that I didn't notice.

• Manipulate the shapes &amp; vectors with Expressions

  Hello

  Is it possible to manipulate the different vectors of a path or shape in After Effects using expressions? How one would call the individual vectors in the script of the expression? If not, are there other ways to draw and adjust the forms via expressions? Thank you

  -Saib

  As I said, you can't. The question here is, you actually want to animate the mask or shape layer paths? Most of which can be done easily with distorting (and much more intuitive, too) as Bézier or the puppet tool. So for me, you simply follow a bad strategy here...

• CS3: Remove the deletion of a page element

  Hello

  Is it possible to remove the deletion of a page element?

  I get the kDeletePageItemBoss in my observer if the user deletes one or more page elements. But I don't know if I can remove the deletion.

  Thank you

  Hans

  Hans,

  One way to do this would be to create a custom implementation of ICommandInterceptor. You can search 'ICommandInterceptor' of this forum and you will encounter an example you could get going in the right direction. Unfortunately, the example is a bit blurred due to the conversion of forum, but it's a start!

  I hope this helps!

• Is it possible to put the property inside the loop node?

  I created three nodes of separation of property (color graphics) for my 3 XY graphs.

  Is it possible to have a property node, put this tag inside the loop where I ranges from 1 to N, and say plot_color_i

  where plot_color_1 would update 1 XY graph, plot_color_2 update XY Graph 2, etc. ?

  See the attached VI.

  Yes.  Create an array of references to the XY graphs and have this auto-index in the property node in the loop For

• Is it possible to display the dynamic value in the ToolTip? I tried: this.assist.toolTip.value = this.rawValue; for a text field 'property MouseEnter', but it does not display the current raw value. It displays a previous raw value of the field... Guilty

  Is it possible to display the dynamic value in the ToolTip?

  I tried:

  this.assist.toolTip.value = this.rawValue; for a text field on 'ownership' MouseEnter

  but it does not display the current raw value. It displays a previous raw value of the field...

  I wrote 'YYYY', but is not displaying on the first mouseEnter event

  

  When I show event mouseEnter for the 2nd time it gives good value.

  

  Now, I changed the "BBBB" value but the first mouseEnter event it displays the value previous i.e. "YYYY."

  

  I found the solution. I wrote the script ("this.assist.toolTip.value = this.rawValue ;") on 'property MouseEnter' but the need to write the script to the "Output" of the field event. ")

  

  Thank you.

• Is it possible to change the timestamp on a photo on the iPhone 6?

  I need a question and answer that emerged in a court case, I'm involved in - is it possible to manipulate or modify the date information on a picture taken on an iPhone 6?

  Yes. The encoded information can be changed using the Windows or Mac photo editing tools. An expert can detect the fact that it has been changed, however.

• Is it possible to draw the same color for each curve automatically

  Hello

  Is it possible to draw the same color for each curve automatically. I use graphic XY basis with data set.

  Lol you'll either need to set the properties through the dialog box.  Or use the nodes property of the graph to adjust the Active plot and then set the color of the plot.  This can be done in a loop For.

  

• Is it possible to view the properties of the class defined by the user as a hierarchy

  So I drag a property node and right-click to display the list of all possible properties.  They are well organized into groups and subgroups etc...

  Is it possible to do the same for the properties I defined for a class?  Let's say I have 20 properties to access data members.  Some of them are related to each other somehow so I want to bring together them on the dropdown property.

  

  I have never tried this, but try to give the names of properties as "Group 1property 1", and "Group 1property 2". " LabVIEW uses this kind of syntax in many other places...

• Is it possible that when the new record is inserted in a table then this empty inserted record is automatically displayed without scrolling?

  Mr President.

  Is it possible that when the new record is inserted in a table then this empty inserted record is automatically displayed without scrolling?

  Because I change the size property of the table 5 range and my new record is inserted at no 10.

  When I click the addRecord button the new parallel line does not appear, do scroll down to see it.

  I want that we don't have to scroll down.

  The line is displayed automatically.

  as shown in the photo my behavior of page.

  

  Concerning

  If you just need the newly created line to be visible,

  You can simply set contentDelivery = 'immediate' and displayRow = "selected".

  P.S. the blog mentioned above only.

• What determines the order that CSS styles class and/or target rule are listed in the menu of the class of the HTML or CSS property inspector in Dreamweaver CC?

  Using Mac OS 10.10.4 and Dreamweaver 8 and Dreamweaver CC 2015 or Mac OS 10.6.8

  What determines the order that CSS styles class and/or target rule are listed in the menu of the class of the HTML or CSS property inspector in Dreamweaver CC?

  Is it possible to change the order in the drop-down list so that a frequently used class style/Targeted rule is listed first (to the top of the list)?

  I just have an attached style sheet and which shows alphabetically in the drop-down list. Maybe, if you have more than one style sheet, the styles appear in the load order of the leaves and alphabetically within each worksheet.

• Manipulate the graduations to get finer resolution labeled tick when you zoom in the graphs

  I have a need to achieve a more fine resolution of the tick labeled in my LineChart when I chose to zoom on a narrow of the chart area. It seems that JavaFX has no support to allow the labelling on the scales, only of the graduations.

  I tried to manipulate the minorTickCount property, but it has the opposite effect of what I'm looking for. For example, to increase the number of minor counties does not reduce the distance between the points of major ticks in terms of value of the axis, and I see no obvious way to actually manipulate what should be the distance between the minor graduations / major in terms of value of the axis. This seems all managed by JavaFX, which is too rigid for my taste.

  I really need to find some sort of solution here, I can't have my axes basically get labeled when the zoom is pretty high for all main scale applies do not at all.

  Does anyone have any ideas? This value opens a feature request for--or already exist? I want to be able to manipulate these axes / ticks more than I currently seem to be able to.

  I have never tried to do something like that, but documentation of the API it seems that NumberAxis.setTickUnit (...) must realize what you need (it sets the distance, in units of the axis between the graduations main brands). You could link it to a dependent value upper and lower too, if necessary.

  Another option would be to subclass NumberAxis and override the calculateTickValues method, although it sounds like it might be difficult.

• It is possible to disable the custom color picker color?

  Hi guys!

  I searched in the discussions on the color picker, but I found something...

  It is possible to disable the option to select a custom color? I work in a company that makes software to Brazilian clients, and not everyone understands English phrases...

  In other words it is the translation of the option, but I don't know if it is possible also.

  Thank you!

  You certainly need to add the stylesheet to the scene, not to anything else. If you take my example and change

  scene.getStylesheets ()...

  TO

  root.getStylesheets ()...

  you will see that it won't work anymore.

  The difference between that and the css that you used, it's that the css you used is applied to the selector button display color; You should apply styles to the popup (color palette), who does not appear in your VBox or AnchorPanes. Notice how the police changed to the name of the color in the button, but it has not changed for the label of 'Personal colour' you are trying to remove.

  Somewhere there is a code that adds the VBox you are subclassing of a scene and this decoration in a stadium. Your best option (maybe second best option, see below) is to find this code, you can add the style sheet to the scene itself.

  If you are working within a framework of someone else wrote and cannot access or modify the code where the scene is set, you have another option I see. Each node has a stage property that refers to the scene which this node belongs. So you can observe the changes made to this property and when it is updated, add the style sheet to the scene.

  So here's a hack to make my original hack works, in case you can not directly access the scene for some reason any:

  final String suppressCustomColorCss = getClass().getResource( "noCustomColorPicker.css").toExternalForm();
  colorPicker.sceneProperty().addListener(new ChangeListener() {
   @Override
    public void changed(ObservableValue observable,
    Scene oldScene, Scene newScene) {
    if (newScene != null) {
    List cssClasses = newScene.getStylesheets();
    if (!cssClasses.contains(suppressCustomColorCss)) {
    cssClasses.add(suppressCustomColorCss);
    }
    }
    }
  });
  

  This code basically says "when the color selector becomes an integral part of a new scene, add the stylesheet to this scene.

  At this point, you're applying notch on top of hack to get the effect you need. I think if I were in this situation I would not go ahead and define my own color chart. What you really need is a menu button, a property for the selected color and a popup with a layout of controls allowing to choose an arbitrary color. It would be a bit of work, but shouldn't be too hard. If you take this option (which I think may be your best bet), it's more work now but it will be clear what you do - when you (or other programmers on your team) eventually return to the code, you will understand how it works much better.

  You must also file two requests for features. An API toggle the option of choosing a custom color, as this seems to be a reasonable piece of functionality to have. The other should be properly internationalized text for the labels in the selector of colors, which are currently just hard coded in the code source in English.

• Is it possible to set the degree of parallel on Auto?

  Is it possible to adjust the degree of the parallel to Auto in the physical model?
  I can see to turn on the parallel and can set the degree of a number, I am just unable to know how the Auto value.
  
  Thank you
  NIC

  Hi Nic,

  By Auto, I assume you mean DOF consisting of PARALLEL on its own, rather than whole PARALLEL.

  It is generated if you set the parallel property to YES and leave blank the level property.
