Setting Kendo UI grid height 100% of wrapper

I know there is an easy way to set fixed height of a Kendo UI grid through their API but for our specific needs, I need to make the grid expand in full height of its wrapper.

With the following markup structure, I set .wrapper to height:600px and I tried to give .k-grid-content height:100% but it doesn’t expand. #grid expands to 100% with height:100% but I need the inside contents to expand as well. How do I achieve that?

Here is the demo JS BIN

<div class="wrapper">
    <div id="grid">
        <div class="k-grid-header"></div>
        <div class="k-grid-content"></div>
        <div class="k-grid-pager"></div>


According to one of Kendo’s tech support team; Dimo Dimov. You should set the height of one container, and everything inside should be set to 100% (including the grid). Then you manually adjust the content height on document ready and window resize.

See here for his example:

See here for yours updated with a js function to set the height of the wrapper to the window height.

Essentially the content is resized with:

function resizeGrid() {
    var gridElement = $("#grid"),
        dataArea = gridElement.find(".k-grid-content"),
        gridHeight = gridElement.innerHeight(),
        otherElements = gridElement.children().not(".k-grid-content"),
        otherElementsHeight = 0;
        otherElementsHeight += $(this).outerHeight();
    dataArea.height(gridHeight - otherElementsHeight);

and the wrapper is sized with (you may need to modify this to suit your layout):

function resizeWrapper() {

Document ready and window resize both call:

$(window).resize(function() {

Relevant css:

#grid {
  height: 100%;

  overflow: hidden;

Frosted Glass Effect in JavaFX?

I’m making an iOS7-themed JavaFX2/FXML project and I was wondering how I could make a Rectangle object have a iOS7-like frosted glass effect.

I’d also like it to have a small shadow. This is tricky, since you might be able to see the shadow behind the semi-transparent object. I’d just like it to be present around the edges.

Is this possible? Here’s a picture showing the desired effect (not including the small drop-shadow):

I'd like it to look like this

UPDATE: Here’s a continuation of the issue. This is going to look amazing :D.


Sample Solution


Run the program below and scroll or swipe up to show the glass pane.

The purpose of the program is just to sample the techniques involved not to act as a general purpose library for the frost effect.

import javafx.animation.*;
import javafx.application.Application;
import javafx.geometry.Rectangle2D;
import javafx.scene.*;
import javafx.scene.Node;
import javafx.scene.control.Label;
import javafx.scene.effect.*;
import javafx.scene.image.*;
import javafx.scene.input.ScrollEvent;
import javafx.scene.layout.*;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import javafx.stage.Stage;
import javafx.util.Duration;

// slides a frost pane in on scroll or swipe up; slides it out on scroll or swipe down.
public class Frosty extends Application {

    private static final double W = 330;
    private static final double H = 590;

    private static final double BLUR_AMOUNT = 60;
    private static final Duration SLIDE_DURATION = Duration.seconds(0.4);

    private static final double UPPER_SLIDE_POSITION = 100;

    private static final Effect frostEffect =
        new BoxBlur(BLUR_AMOUNT, BLUR_AMOUNT, 3);

    @Override public void start(Stage stage) {
        DoubleProperty y = new SimpleDoubleProperty(H);

        Node background = createBackground();
        Node frost      = freeze(background, y);
        Node content    = createContent();

        Scene scene = new Scene(
                new StackPane(


        addSlideHandlers(y, content, scene);

    // create a background node to be frozen over.
    private Node createBackground() {
        Image backgroundImage = new Image(
        ImageView background = new ImageView(backgroundImage);
        Rectangle2D viewport = new Rectangle2D(0, 0, W, H);

        return background;

    // create some content to be displayed on top of the frozen glass panel.
    private Label createContent() {
        Label label = new Label("The overlaid text is clear and the background below is frosty.");

        label.setStyle("-fx-font-size: 25px; -fx-text-fill: midnightblue;");
        label.setEffect(new Glow());
        label.setMaxWidth(W - 20);

        return label;

    // add handlers to slide the glass panel in and out.
    private void addSlideHandlers(DoubleProperty y, Node content, Scene scene) {
        Timeline slideIn = new Timeline(
                new KeyFrame(
                        new KeyValue(

        slideIn.setOnFinished(e -> content.setVisible(true));

        Timeline slideOut = new Timeline(
                new KeyFrame(
                        new KeyValue(

        scene.setOnSwipeUp(e -> {

        scene.setOnSwipeDown(e -> {

        // scroll handler isn't necessary if you have a touch screen.
        scene.setOnScroll((ScrollEvent e) -> {
            if (e.getDeltaY() < 0) {
            } else {

    // create a frosty pane from a background node.
    private StackPane freeze(Node background, DoubleProperty y) {
        Image frostImage = background.snapshot(
                new SnapshotParameters(),
        ImageView frost = new ImageView(frostImage);

        Rectangle filler = new Rectangle(0, 0, W, H);

        Pane frostPane = new Pane(frost);

        StackPane frostView = new StackPane(

        Rectangle clipShape = new Rectangle(0, y.get(), W, H);


        return frostView;

    public static void main(String[] args) { launch(args); }

Answers to additional questions

“JDK 8,” would that happen to be a requirement of this?

The sample code above is written against JDK 8. Porting it back to JDK 7 by replacing the lambda calls with anonymous inner classes is pretty trivial.

In general, Java 7 is pretty dated for JavaFX work. I advise upgrading at your earliest convenience to work with a Java 8 minimum version.

initiating your Panes with arguments

More convenient constructors for most parent nodes is a Java 8 feature. You can easily convert the Java 8 format:

 StackPane stack = new StackPane(child1, child2);

To Java 7:

 StackPane stack = new StackPane();
 stack.getChildren().setAll(child1, child2);

will this working if the desktop is behind a frosty pane?

Not directly, you can create a new question for that.

angularJS filter expression in ng-repeat

I would like to know what is the most elegant and simple way to implement this. I need to add a filter expression for a ng-repeat that would filter 2 conditions from one property.

In this example

  • If you enter A, it would display checkbox for A,
  • enter B – display checkbox for B.

But I want to display the specified checkboxes plus anything with empty condition. There is no condition for C, so:

  • if you enter A, I want to display both A and C checkboxes,
  • enter B, I want to display both B and C checkboxes.


I would create custom filter like:

app.filter('myfilter', function() {
   return function( items, condition) {
    var filtered = [];

    if(condition === undefined || condition === ''){
      return items;

    angular.forEach(items, function(item) {          
       if(condition === item.condition ||  item.condition === ''){

    return filtered;

and usage:

<span ng-repeat="charge in charges  |  myfilter:level.condition">

See Demo in Plunker

It looks pretty elegant and clear.

Hope it will help


Error – “java: cannot find symbol” in IntelliJ IDEA

I want to run my project but IntelliJ IDEA version 13 shows some strange error message:

enter image description here

Now class file has some small cross at class icon.

But this code was compiled, I couldn’t figure out this strange behavior.

How to solve this trouble?


I believe the class is excluded from compilation – I think I’ve had this before.

Try: Settings -> Compiler -> Excludes


Android: Directory and file chooser android library

I’m using aFileChooser android library project in my app to select the file from external storage. but it doesn’t seem to pick only directory to let user select the download location to download the files. Is there any android library project which support both pick file and pick directory?

I understand there are multiple questions have been answered here either for file chooser or directory chooser but after extensive search I couldn’t find one for both directory and file chooser. Any help would be appreciated.


I have no android library project, but you can simply make your own file chooser with the next code. This code will ask you to chose a file browser, when you select a file in the file browser you’ll get the path in the onActivityResult function in the FilePath String.

Create this public:

private static final int ACTIVITY_CHOOSE_FILE = 3;

When a button is clicked you can call this:

            Intent chooseFile;
            Intent intent;
            chooseFile = new Intent(Intent.ACTION_GET_CONTENT);
            intent = Intent.createChooser(chooseFile, "Choose a file");
            startActivityForResult(intent, ACTIVITY_CHOOSE_FILE);

You can catch the directory with this code :

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode != RESULT_OK) return;
        String path     = "";
        if(requestCode == ACTIVITY_CHOOSE_FILE)
              Uri uri = data.getData();
              String FilePath = getRealPathFromURI(uri);


public String getRealPathFromURI(Uri contentUri) {
    String [] proj      = {MediaStore.Images.Media.DATA};
    Cursor cursor       = getContentResolver().query( contentUri, proj, null, null,null); 
    if (cursor == null) return null; 
    int column_index    = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    return cursor.getString(column_index);

Edit: If you do not want to use an external file browser, you can import this android library into your project:
