Is it possible to forbid the selection in the TextField?

I have a small problem: my text field keeps selecting itself, for example if I alt - tab application.

For my application, text selection is not required and is not used - so I want to dismiss this annoying behavior. In fact, just implemented selection transparent or white color works perfectly.

Is it possible to do this?

just implemented selection transparent or white color works perfectly.

Having an editable field without being able to see the selections on the ground seems kind of strange to me. But anyway, you can do so via css:

textField.setStyle("-fx-highlight-fill: null; -fx-highlight-text-fill: -fx-text-fill;");

Create a style .text-entry style sheet if you want to apply the style to all text entry fields.

See the JavaFX css reference guide for answers to all your questions on css: http://docs.oracle.com/javafx/2/api/javafx/scene/doc-files/cssref.html

You can also listen on the selectedTextProperty and clear the selection, whenever something is selected.

Sample application:

import javafx.application.Application;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.scene.Scene;
import javafx.scene.control.TextField;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class TextFieldHighlightFill extends Application {
  public static void main(String[] args) { launch(args); }
  @Override public void start(final Stage stage) throws Exception {
    TextField standardTextField = new TextField("Plain Jane");

    TextField styledTextField = new TextField("Jumping Jackrabbits");
    styledTextField.setStyle("-fx-highlight-fill: null; -fx-highlight-text-fill: -fx-text-fill;");

    final TextField forbiddenTextField = new TextField("Happy hippopotamuses");
    forbiddenTextField.setStyle("-fx-highlight-fill: null; -fx-highlight-text-fill: -fx-text-fill;");
    forbiddenTextField.selectedTextProperty().addListener(new ChangeListener() {
      @Override public void changed(ObservableValue observable, String oldValue, String newValue) {
        if (newValue != null || !newValue.isEmpty()) {
          int caretAt = forbiddenTextField.getCaretPosition();
          forbiddenTextField.selectRange(caretAt, caretAt);
        }
      }
    });

    final VBox layout = new VBox(10);
    layout.getChildren().addAll(standardTextField, styledTextField, forbiddenTextField);
    layout.setStyle("-fx-padding: 10; -fx-background-color: cornsilk;");
    stage.setScene(new Scene(layout));
    stage.show();
  }
}

    In general, Yes, if the function is a function table, you can do something like:

    select  t.col1,
            t.col2,
            f.col1,
            f.col2,
            f.col3
      from  table_name t,
               table(some_table_function(param1,...paramN)) f

  • is it possible to change the selection without re-lasso using the magnetic lasso?

    When you use the lasso to select someone in a photo, perhaps not usually SO accurate sound in some places.  for the lasso of the cuts in the area of the photo you want to cut, I find that I have to start the process.  Is there a way to go back a few points and try again?

    Once I finished the lasso and I see that the points of this Cup in the picture, is possible to edit the edges of the selection?

    Just go in the Quick Mask by pressing Q.

    This converts the selection to a red mask.

    You can then add or subtract the mask with a hard brush.

    Once finished, press Q again.

    I don't think there are beacons of style that would allow you to change the colors highlighted. As you say it is determined by the operating system settings.

  • Is it possible to sort the images by file name?

    I imported a record of 200 images in Photos for OS X (El Captain). Image files have been appointed in the order - I want them to appear in a slide show: photo_01, photo_02 etc...

    Once I imported the images - I found them all out of order - and the only options I can find in the view menu are somehow 'oldest first', 'newest first' or ' title '. Please, someone tell me I'm missing something obvious - he and not that Apple chose to omit the possibility to sort the images by name? If this is the case - I'm speechless - how is f - ing stupid!

    Sort by file name is not an option in the Photos. Albums and smart albums you yourself set can be sorted by name, date of capture, or manually.

    Sorting through the predefined albums is automatic:

    • 'Photos' display with moments and collections is sorted by date of capture and the location.
    • 'All the Photos' display is sorted by the date of the import session.
    • Other built-in smart albums are sorted by the date of capture.

    You can see the current sort order, preset, if it is grayed out in the "view > sort ' menu.

    As a workaround:

    1. If you need to want pictures to be sorted by file name, copy the name of the file in the title field. Then, create a smart album of the items and sort by title. We have posted a trick to copy the name of the file in the title field for the selected photos: Script: change the title filename without Extensionor: Script: batch change the titles of the Extension/w
    2. Or view your photo library in pictures of power.  This versatile tool lets you browse photos as a list or thumbnail while looking the other metadata under the thumbnails or displayed as list with columns selected and sorted by columns.

    You can do a lot with the free trial: download PowerPhotos here: Fat Cat Software-PowerPhotos

  • Is it possible to keep the timer "always on top"?

    When you use the timer I like to keep the timer of disappearing from the screen saver, but I didn't understand how to do... If that's possible.  After the timer starts, he goes down to a few seconds and the clock face appears again.  To check the time remaining on the timer, you must click to the home screen and select new application timer... which, in few seconds again goes to the background and the face of the clock reappears, again he must open the clock app to see the remaining time.  If there is a way to keep the timer "on-top" without having to repeatedly touch the screen during execution of the timer, I have not discovered.  I would also add the timer to my eyes so I can toggle to him as well.  Of course, I can do it on my iPhone, but the Watch has not yet this ability.  Apple engineers could make sure with the timer and the timer if they see the need.  Are there others who want that ability as well?  I think so.

    Hello

    It is not currently possible to add Timer looks. However, your watch can be configured for more convenient use of the application of the timer:

    • Set your watch to return to the last app used to raise your wrist:
      • On your iPhone, in the application of the watch, go to: Watch My > General > wrist Detection - turn on.
      • On your iPhone, in the application of the watch, go to: Watch My > General > screen Wake:
        • Raise the topic on the wrist, select RESUME last activity.

    After you start a timer by opening the timer app, your watch will return to timer (for as long it remains the last app used) when you then lift your wrist.

    • Add a Timer to your dial of the watch as a complication. When you view the time on your watch:
      • Firmly press the display > drag left / right to the face of the watch you want to customize (not to slip if you want to customize the current face of the watch).
      • Press the Customize button.
      • Some watch faces offers more than one screen customization options > move left until you reach the last screen to select (if available) complications.
      • Tap a complication to customize what is shown in this place.
      • Turn the digital Crown to scroll through available there complications until you reach Timer.
      • Press the digital Crown, then press the dial to return.

    To start the timer directly from your watch dial, press the complication. Once started, the remaining time will be then showed complication on your watch until the end of the timer dial, when the application opens for you to make them disappear.

  • A60-106: is it possible to upgrade the DVD/CD-RW combo

    Hello. Anyone know if it is possible to upgrade the DVD/CD-RW combo on my A60-106? There is nothing wrong with the origonal, but DVD write speeds also have multiplied since I my A60. I burn a lot of discs, and any increase in speed would be a major asset. If the upgrade is possible, am I limited to real Tosh or is there any of the third-party available-based jobbies. My current drive is a Pioneer DVR-K13A.

    Thanks in advance.

    Brian

    Hi Brian,.

    You can certainly replace your optical drive with a new. You will need to ensure that the new disk is the same size as the original (i.e. its physical dimensions), and uses the same connectivity as your original (master, slave, or Cable Select). This last point can be problematic, because very few third-party resellers list actually what setting of their readers.

    As for the actual burn speed, you can see that other factors will affect this. you will find many posts in these forums related to the low burning rate.

    Good luck

  • Using pictures of Yosemite 1.0.1 I created a 400 photo album. I custom sort them. When I copy a USB to share with friends my custom sort is lost. Is it possible to maintain the current order of photo on a USB?

    Using pictures of Yosemite 1.0.1 I created a 400 photo album. I custom sort them. When I copy a USB to share with friends my custom sort is lost. Is it possible to maintain the current order of photo on a USB?

    Of course, not as the sorting, the viewer sees is defined by them not by you - given the same USB you can use the finder to display in alphabetical order, last updated order etc. size - files have no command - the viewer defines the order

    You can select Photos and export using a file for sequential access to export name so if the Viewer uses an alpha sort they correspond to your order desired - you can facilitate this, but they must define their queue viewer correctly for them to see it as you wish

  • Not possible to use the Nvidia GPU both graphics primary source all the time?
