Changing drop Down Text in JAVAFX after the page is loaded - javafx-2

How do I change the text size in the drop down in java FX? Currently it's not coming out correctly as per the css. Looks fine when I run the url through a browser. However the drop down text sizes are coming out very small when the url is loaded and viewed in JAVA FX.
Here is my code:
public void start(Stage stage) throws InterruptedException {
stage.setTitle("test");
Pane stackPane = new Pane();
Browser browser = new Browser();
stackPane.getChildren().add(browser);
Rectangle2D primaryScreenBounds = Screen.getPrimary().getVisualBounds();
webScene = new Scene(stackPane, primaryScreenBounds.getWidth(), (primaryScreenBounds.getHeight()-50), Color.web("red"));
webScene.getStylesheets().add(this.getClass().getResource("main.css").toExternalForm());
stage.setScene(webScene);
stage.show();
}
public Browser() {
//apply the styles
getStyleClass().add("browser");
String url = "http://localhost:8000/myapp";
webEngine.load(url);
getChildren().add(browser);
}

BrowserComponent with Infiniteloop

How do I add an Infinite progress till the WebPage is fully loaded?
Form hi = new Form("Hi World");
hi.setLayout(new BorderLayout());
final BrowserComponent wb = new BrowserComponent();
hi.addComponent(BorderLayout.CENTER, wb);
final Dialog ipDlg = new InfiniteProgress().showInifiniteBlocking();
wb.setURL("https://www.codenameone.com");
wb.addWebEventListener("onLoad", new ActionListener() {
#Override
public void actionPerformed(ActionEvent evt) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
});
hi.show();
ipDlg.dispose();
above is the code I am using.
This won't work since dialog is literally a separate Form. So the browser component will never load and won't show what's going on below.
You can use an InteractionDialog which is just a Container in the layered pane. This means the browser will keep loading and you can draw on top of it. Just add the InfiniteProgress into the InteractionDialog and show it.

Online Pdf viewer with pinch zoom throws exception after close activity

I want to open a PDF file from server in web-view with zoom facilities.
I am using webView.setBuiltInZoomControls(true) but it throws an exception after close activity.
I am using below code:
webView = (WebView) findViewById(R.id.webView);
webView.getSettings().setSupportZoom(true);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
webView.loadUrl(url);
return false;
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
}
});
webView.loadUrl("http://docs.google.com/gview?embedded=true&url=" + data.getTypeUrl());
Exception is :
android.view.WindowLeaked: Activity has leaked window android.widget.ZoomButtonsController$Container that was originally added here
Try this:
// make sure your pinch zoom is enabled
webView.getSettings().setBuiltInZoomControls(true);
// don't show the zoom controls
webView.getSettings().setDisplayZoomControls(false);

JDialog doesn't size correctly with wrapped JTextArea

While making a program, I noticed a bug with the JOptionPane.showMessageDialog() call. I use a button to create a JTextArea that wraps and then display a dialog containing this text area.
If the text area is too large, however, the dialog does not size itself correctly to the height of the JTextArea. The Dialog cuts off the OK button in this example.
I replicated the bug in the following code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class DialogBug {
public static void main(String[] args) {
final JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
final String text = "looooooooooooooooooooooong text looooooooooooooooooooooooooooooooooooooong text";
JButton button = new JButton();
button.setPreferredSize(new Dimension(30, 30));
button.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
JTextArea area = new JTextArea(text, 0, 50);
area.setEditable(false);
area.setLineWrap(true);
area.setWrapStyleWord(true);
area.append(text);
area.append(text);
area.append(text);
JOptionPane.showMessageDialog(frame, area, "why does it do this", JOptionPane.WARNING_MESSAGE);
}
});
frame.add(button);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
}
I would post a picture, but I don't have enough reputation...
Is there a way to fix this without having to use a JScrollPane?
Here's a screenshot:
If you run the pack command on the dialog (a function in the Window class) it will resize based on subcomponents. For your case you will have to rewrite without using the showMessageDialog() to get the resize to work (so make the dialog first, add the text, pack, then show it)
Dialog b = new Dialog();
// add stuff
b.pack();
For my test code it worked perfectly to get the dialogs to be the right sizes
Without pack()
With pack()

Resizing GXT Window When Browser Window Resizes

Developing using GXT 2.2.5 on GWT 2.3.0.
The application I'm working on displays a resizable Window with auto scrollbars. I want to make sure the Window size does not exceed the size of the browser window it gets displayed in. To that effect, I added the following code:
addWindowListener(new WindowListener()
{
public void windowActivate(WindowEvent we)
{
super.windowActivate();
Window window = we.getWindow();
window.layout(true);
int width = window.getWidth();
int height = window.getHeight();
int maxWidth = XDOM.getViewportWidth();
int maxHeight = XDOM.getViewportHeight();
window.setSize(Math.min(width, maxWidth), Math.min(height, maxHeight));
window.center();
}
};
This manages sizing the Window to fit in the browser when it gets opened quite nicely.
My problem is that if the user then resizes the browser window, the open Window does not adjust and ends up being clipped.
Is there some way for me to either force the Window to stay within the boundaries of the browser, or capture the resize event so that I can tell the Window to resize accordingly?
Thanks.
You need to add the listener (actually handler -- listeners got depreciated) to the browser window.
So if you have several different windows you show at different times that all need to be resized with the window, you need to have a listener for each window and add it to the browser window when the window is shown.
To add a listener to the browser Window, use:
com.google.gwt.user.client.Window.addResizeHandler(handler);
So for example to resize ContentPanel cp:
com.google.gwt.event.logical.shared.ResizeHandler handler = new ResizeHandler() {
#Override public void onResize(com.google.gwt.event.logical.shared.ResizeEvent event) {
cp.setWidth(event.getWidth());
cp.setHeight(event.getHeight());
}
};
So then if you switch to a new view or ContentPanel you need to register that...
com.google.gwt.user.client.Window.addResizeHandler(handler2);
com.google.gwt.event.logical.shared.ResizeHandler handler2 = new ResizeHandler() {
#Override public void onResize(com.google.gwt.event.logical.shared.ResizeEvent event) {
cp2.setWidth(event.getWidth());
cp2.setHeight(event.getHeight());
}
};
NOTE:
You can't do event.getWindow() for the ResizeEvent you need to handle that another way.
Actually I tend to do it in a constructor like:
com.google.gwt.event.logical.shared.ResizeHandler handler2;
public MyDialog(){
handler2 = new ResizeHandler() {
#Override public void onResize(com.google.gwt.event.logical.shared.ResizeEvent event) {
setWidth(event.getWidth());
setHeight(event.getHeight());
}
};

Common menu item for all scenes in Java FX

I want to develop a multiple scenes Java FX application. But I want to have the common menu across all scenes. I think using FXML I can create a menu in a scene. But Can I have the same menu across all the scenes even after I navigated to other screen?
If so how is it. Else let me know any alternative for it.
Yes this is possible. I'm using this mechanism in my own application.
What I do first is make an FXML with the menu bar and an AnchorPane who contains the content. This FXML is loaded when the application starts.
I use a Context class (based on the answer of Sergey in this question: Multiple FXML with Controllers, share object) which contains a method ShowContentPane(String url) method:
public void showContentPane(String sURL){
try {
getContentPane().getChildren().clear();
URL url = getClass().getResource(sURL);
//this method returns the AnchorPane pContent
AnchorPane n = (AnchorPane) FXMLLoader.load(url, ResourceBundle.getBundle("src.bundles.bundle", getLocale()));
AnchorPane.setTopAnchor(n, 0.0);
AnchorPane.setBottomAnchor(n, 0.0);
AnchorPane.setLeftAnchor(n, 0.0);
AnchorPane.setRightAnchor(n, 0.0);
getContentPane().getChildren().add(n);
} catch (Exception ex) {
System.out.println(ex.getMessage());
}
}
So what basically happens is:
When the program starts, set content pane in the Context:
#Override
public void initialize(URL url, ResourceBundle rb) {
Context.getInstance().setContentPane(pContent); //pContent is the name of the AnchorPane containing the content
...
}
When a button or menuitem is chosen, I load the FXML in the content Pane:
#FXML
private void handle_FarmerListButton(ActionEvent event) {
Context.getInstance().showContentPane("/GUI/user/ListUser.fxml");
}
Hope this helps :)
