JavaFX 2.0 :: Float Modeless Popup On Top Of All Other Content
Jun 1, 2014
I have a case where I want to float a modeless popup on top of all other content. Seems like a Popup is ideal for this. Except for the following annoyances:
I don't see any way to tie its position to some owner window. You can supply an initial anchor position, but I noticed that if I drag the frame of the app window containing the JavaFX application, the Popup remains where it is and can actually appear outside the bounds of the App! I find this very disconcerting. I suppose I could bind its position to the screen coords of the Stage, but it would seem that I should not have to do this.If I minimize the app, the Popup remains visible. Rather odd given that when I called Popup.show(Window), you would think when the owner Window got hidden it would hide the owned Popups too. Again, I could probably bind to some property on the Stage, but like (1), it seems you should not have to do this.
I haven't tried this while embedding the Scene in a browser. I certainly hope that these Popups should not be allowed outside the bounds of the browser window. That spells trouble.
Is there an existing way to bind the content of a ListProperty? Consider the following:
private final ListProperty<Worker<?>> workers = new SimpleListProperty<>(FXCollections.observableArrayList()); public ListProperty<Worker<?>> workersProperty() {return workers;} public ObservableList<Worker<?>> getWorkers() {return workers.get();} public void setWorkers(ObservableList<Worker<?>> workers) {this.workers.set(workers);}
[Code]...
What I want to do is bind the content of the stateWatchedWorkers list to workers. If the entire workers list is replaced, I want stateWatchedWorkers to be updated to match the content of the new list. Put another way, I want the stateWatchedWorkers list to be mapped to the current list being held by the workers property.
I am facing an issue with the TableView in Java FX 8.
I am having a TableView created with data with scrollbars automatically added in when the Window is minimized. I moved the horizontal scrollbar to right and then maximized the window to full.
After this the column headers remained no longer aligned with the content. When I click on any column header then the header aligns with the content.
The Issue is replicable also in case when a vertical scrollbar gets automatically added to a table view with preloaded data...
I am trying to figure out the best way to load localized versions of FXML content. I know that I can localize strings, images etc. by specifying a ResourceBundle when loading the FXML using FXMLLoader with a ResourceBundle. But what about if you need to tweak the FXML for different locales (eg, adding more real estate for certain elements, different fonts, etc). Is there any way to create localized versions of FXML content? The only thing I can come up with is a naming convention like MyForm.fxml, MyForm_de_DE.fxml, ... and trying to load them based on the locale, but I'd have to come up with my own fallback for specific locales that aren't found.
I want to create a ScrollPane where I can scale the contents. Think of a simple drawing program that allows you to zoom in and zoom out.
If I create a ScrollPane in SceneBuilder and then drop a couple of Circles into the AnchorPane all looks good.
If I then set a scale of 0.5 for the AnchorPane Scale X and Scale Y the AnchorPane gets scaled about its centre leaving space between the left and top edge of the AnchorPane and the left and top edge of the enclosing ScrollPane.
The only way to get the AnchorPane so that it aligns with the top left of the ScrollPane seems to be to add a negative amount to Translate X and Translate Y.
In my application I would like the user to be able to adjust the zoom (Scale) continually and also the size of the AnchorPane must be allowed to change as the user add/deletes/edits content.
Does this mean I have to continually monitor the AnchorPane properties and set compensating Translate X and Translate Y values each time? Or is there an easier way to achieve what I want?
I'm using the tableview-component. The size of font of header is greater then that of cells. The problem is: the width of the column bases on the cell with the longest string and if the header-string is longer then the header gets truncated (it shows ellipsis) and I have to change the width of column manually. How could I solve this problem? The easiest way would be to compute the column-width on myself. I can't find any method in javafx, that would allow to compute the width of string in pixels. In Swing there is the FontMetrics class and Graphics class, so it is easy to get the width in pixels. Are there any pendants to this classes in JavaFX?
Is it possible to make it so that when the popup box comes up I will only be able to click on the box? For example, I would be browsing the internet while the program is running and then the box pops up and I am forced to answer the question before I can click on anything else. If it is possible, how do I do it?
I have created a swing application which has a TrayIcon, this has one button that has the following code:
displayItem.addActionListener( new ActionListener(){ public void actionPerformed(ActionEvent e) { trayIcon.displayMessage("Hello Title","Hello World", TrayIcon.MessageType.WARNING); } }); [/highlight]
I have another class which I run via the following:
Thread counter = new Thread(new regCheck()); counter.start();
And within this "start" method I want to be able to wait 10 seconds and then trigger the popup that appeared within the original class. I think that the right method of achieving this is to create a function within my original class causes the popup.
public void display(String a, String b) { trayIcon.displayMessage(a,b, TrayIcon.MessageType.WARNING); }
However I have two issues here:
-firstly I dont know how to get the original trayIcon image from the method it was initialized into this new method. -secondly I dont know how to trigger this event from the other class. Here is the method that I tried (but doesnt work)
window w = new window(); w.display("a","b");
This doesn't work because window's main begins to run and endlessly creates multiple windows and TrayIcons. What is the correct way to implement this sort of behaviour?
I am having issue with jmenu popup in netbeans. It only sometimes works. Sometimes I don't get a java popup at all. Sometimes my File and Edit options are completely missing. This is what my code looks like.
import javax.swing.*; public class menu { /** * @param args the command line arguments */ public static void main(String[] args) { // TODO code application logic here JFrame f = new JFrame(); f.setVisible(true);
Is there a way to connect the popupmenu to the right Object (JFrame).
(Something like SwingUtilities.getWindowAncestor(popupmenu)
I've created 2 JFrames each with the same MouseClass. When you click on the RMB a pop menu is shown with a background item. When clicked on the background item only the last created JFrame changes his background.
Below is my simplified code. I'm probably not thinking like a good OO'er.
I am developing my college's project in JSP using jquery to open a magnific popup when user clicks on a link and the in the magnific Popup must be fetched from Mysql and i tried two approaches for this:
1. magnific Popup type is ajax here i passed the variable value in the link of href (after '?') to another JSP page where connection to database is created and queries are written in JSTL to fetch data and show this in magnific Popup .. But i failed in this approach, don't know in another JSP page the data without having database connection is loaded in the magnific Popup easily but not database data..
2. magnific Popup type inline here i need to pass the variable value in the same page between different tags..
We created one web application which runs on tomcat 7.0.35 using spring mvc 3.0 . Its working perfectly on 32-bit windows machine in IE 8 on Windows 7 OS, when we tried to run this on 64-bit windows 2008 Server, jquery is not working. Also I populate data from Pop-up JSP to parent JSP, and it works 3/10 times only and does not work always.
We used the following jquery plugins in our project
I have a combobox with this PopupMenuListener. All works fine, except that the popupMenuWillBecomeInvisible method does not capture the selection made and neither does it show the selection.
PopupMenuListener pmlMqMessagePurged = new PopupMenuListener() { @SuppressWarnings("unchecked") public void popupMenuWillBecomeVisible(PopupMenuEvent arg0) { try { JdbcSqlServerDataSource ds = new JdbcSqlServerDataSource( DbConnectionURL.UToolDbHostName, 0,
[Code] .....
The popupMenuWillBecomeInvisible does fire but the System.out.println() returns 'nul'l as answer to the value i have selected from the combobox.
Main screen leftsecond screen rightswing portal application is visible on two screens. If you open a context menu (right mouse) on the right screen, the context menu open on the left (Main) screen instead of the right.
Will I'm tying in my code to set a default number for the JTextField that when the user decide not to put any numbers. Like let say that I want the textfield set to 0 , so then the user do not file it it won't make any problem to the program because its already has a default number.
Note: This is a small part of my code. when I leave it empty it take the 0 as a value, However, when I write in text field it also take the value of a 0 and the finalTotal is also = to 0.what I'm doing wrong.
I am getting the blank value in the array and this code is passed in IVR for playing the values since the first value is blank the prompts arrangements is disturbed. I want to replace the blank space or value by zero.
How do I write a program that shows the max and the min value of a float integer? like for example in order to get the max value of a long integer we type System.out.println(Integer.MAX_VALUE); How would I do that for a float integer?
Ok, so in my quest to achive perfect ray casting and line/plane intersection, what I believe to be my last problem is precision of a float. I need some precision (0.000) but I am dealing with the difference of (-1.000000000) and (-1.000000002), where the second number would be completely off. I looked at DecimalFormat, but that just puts it into a string, I need actual loss of precision.
Java Code:
DecimalFormat form = new DecimalFormat("0.00"); String newX = form.format(x); String newY = form.format(y); String newZ = form.format(z); x = Float.parseFloat(newX); y = Float.parseFloat(newY); z = Float.parseFloat(newZ); mh_sh_highlight_all('java');
Doing an early exercise out of the Java Examples in a Nutshell book and they are asking for 'an efficient search algorithm to find the desired position' of two floats in a sorted array that bound an int. My try is below:
public static int search(int searchnum, float[] nums){ int low = 0; int high = nums.length - 1; int mid = (low + high) / 2; while(low < high){ if(nums[mid] < searchnum){
[Code] ....
This is working for the example but I would like to know if it is considered 'efficient' or even good?
I am trying to write a Float Array to a file but it is only writing the last line of the array to a file. I have also attached the entire assignment as a zip file with all required files. Here is the part of the code I am having issues with:
