• Auto-Filtrer elements in an editable ComboBox

  Hello world
  
  I have a < MyItem > editable ComboBox. When I type in the textfield of the combobox I want to filter the items accordingly and then select an available item.
  
  Does anyone do this?
  
  I'm ChangeListeners adding to:
  
  .selectionModelProperty () .getValue () .selectedItemProperty)
  .editorProperty () .getValue () .textProperty)
  . valueProperty()
  
  without success.
  
  See you soon,.

  It of pretty convenient, but not perfect. The trick I used here was to avoid filtering if the text in the editor of value through a selection is made. It will not automatically change the selection (the label at the bottom watching the current selection). When I tried to do, it seemed to destroy any reasonable notion of what is selected in the editor.

  The commented code is an attempt to return to the full list on a selection is made. It seems that it works, to delay treatment until after that default managers were called; That is why the Platform.runLater (...). This definitely falls into the category of the 'hack' and maybe not particularly desirable from the point of view ergonomics anyway. In addition, scrolling is kinda weird by activating this option; If you type, and then use the arrow keys for selection, it won't scroll the selected item on the first press of the arrow keys.

  A similar thing happens with the modification of the text selected in the Editor: it seems to only work if you reschedule using Platform.runLater (...). It is not clear to me why, but do not make this mess up typing a bit.

• Flex 4 component editable ComboBox no spark

  I have recently started to use the version Release of Flash Builder 4, after using the beta for a while.  In the beta, the ComboBox component has a property called editable, allowing you to change the textInput component in the combobox.  If you don't want it to be editable, you can set this property is false.  With the Release version, it seems that the "editable" property isn't there anymore, and I can't figure out how to make non editable ComboBox.  Is there a way to do this?

  Use s:DropDownList instead.

• Editable ComboBox bug?

  Hello

  I reproduce a ComBox behavior which I suspect to be a bug in a small example.

  When the TextField object intercepts the event, the println displays the current value = > OK

  When the ComboBox control (which is editable) intercept the println event does not display the current value = > bug?

  @Override

  {} public void start (point primaryStage)

  TextField textField = new TextField();

  ComboBox comboBox = new more;

  comboBox. setEditable (true);

  EventHandler, eventHandler (event e) =-> {}

  System.out.println ("textField text:" + textField.textProperty () .get ());

  System.out.println ("comboBox value:" + comboBox.valueProperty () .get ());

  };

  textField.addEventFilter (KeyEvent.KEY_RELEASED, eventHandler);

  comboBox.addEventFilter (KeyEvent.KEY_RELEASED, eventHandler);

  Root StackPane = new StackPane();

  VBox, vBox = new VBox (textField, comboBox);

  root.getChildren () .addAll (vBox);

  Scene = new scene (root, 300, 250);

  primaryStage.setScene (scene);

  primaryStage.show ();

  }

  Could you please confirm if this is a bug?

  Thank you

  Olivier

  In fact, it's not a bug, I found the right way to get the value:

  System.out.println ("comboBox value:" + comboBox.getEditor () .textProperty () .get ());

  Instead of

  System.out.println ("comboBox value:" + comboBox.valueProperty () .get ());

  Sorry for the inconvenience

• Make the object selected in a ComboBox

  Hi all
  
  don't know why I do not understand the mechanics of JavaFX... How can I do a rendering custom object displayed/selected (some classes, used for example). The rendering of the list is done by a cellfactory, but I can not find the method of the selected object.
  
  Please answer this for a modifiable and a non editable combobox.
  
  Thank you in advance, Tim

  Keep in mind that at the point 2.2, ComboBox has 2 instances of ListCellFactory: one for one for his button and the pop-up list combo (combo collapsed, the part that lies before the arrow). Using those you can return the same object differently (ie: 1 line - brief description of the key and several lines + details + icon for the popup list).
  In paragraph 2.1 of FX, there is only 1 ListCellFactory and it applies both on the button and the list.

• limit max char in combobox

  I have an editable combobox. Is it possible to limit the number of characters to 20 characters? I know that this must be a Javascript if possible but do not know how to code or where it's going (validation custome, key race script etc) any help would be great!

  Thank you!

  Ken

  Add a new function to a JavaScript to the document level that looks like:

  Limit the number of characters that can be entered

  function ks_maxchars (max) {}

  Get all the characters that have been entered

  var v = AFMergeChange (event);

  Reject change if it will not exceed the maximum allowed

  If (v.length > max) {}

  Event.change = "";

  }

• How to set the focus to the ComboBox control via actionsript?

  Hello

  I wanted the focus (describing the border) on a TextInput(id:myTextInput) and ComboBox(id:myComboBox) in actionscript. I tried myTextInput.setFocus (); that works very well for the TextInput component. In the case of ComboBox, myComboBox.setFocus (); works if and only if the ComboBox editable property is set to true. It does not work if it is not editable ComboBox. I wanted to put the focus on an uneditable combo box... Pls help... How can I achieve this?

  Hello

  Try this:

  focusManager.setFocus (myComboBox);

  focusManager.showFocus ();

  Hello everyone

  I'm developing an application for use in a tablet. Everything´s works fine except that the combobox control that I use is really difficult "hiring" cause it s size, not the text box, but more particularly the selector to display items. I need to make bigger somehow. Please need help how can I achieve this.

  Thanks in advance, Esteban.

  Did you change the editing mode of the key icon to the icon of tweezers?  When you do this, you can change the individual components that make up the control.

  I am a novice in programming as well as the CVI. Please explain in detail if anyone knows.

  You can do this, but it will shows. You can add columns in the control ring menu, so you'll have to create your own popup with a tree control that replaces the menu ring. I have attached a sample program as proof of concept and you get started.

• Table 2D 1 d array of combobox

  Hi, I have a question,

  I have a chart of the combobox, I want to fill every single comboboxes from one of the dimension of the 2d array.

  I tried with a cluster, and it works. When I work with a 1 d table, I don't have the option to iterate through each element inside since it is a 1 d table.

  Thank you.

  It is not possible.  All elements of an array have the same properties (except Position, value, & Focus button).  In an array of combo boxes, each element must have the same set of strings.

  It is true what you say about the paintings, but is not true that this is not possible.  Here, I've posted an example where there is an array of clusters, with a combo box and a string.  The chain is sorta like a filter and only shows items from mailbox that match this combo string.  Thus, in this way, it seems that several list boxes drop-down list box different elements, but really, they change just when the user interacts with the drop-down list box.
