View Replies View RelatedI've searched everywhere but found no way to disable loading of images by Java WebEngineHow to do it?
Research done:
I found some ideas, such as using URL.setURLStreamHandlerFactory() to use my own URLStreamHandler, and having that analyze the URL to only return URLConnections for URL's that don't end in .jpg .png etc.
But that has many problems: Sometimes the image url doesn't end in .jpg, if it's a dynamic image, such as a captcha. So how can I disable automatic image loading from WebEngine?
How do I keep an item (TreeItem) from being selected when performing a drag -n- drop? I don't want it to be selected because it will end up making the target disappear (selection of TreeItem changes target panel).

View Replies View RelatedI have a requirement where in the content of the text area is dynamically populated from the database. I am able to successfully retrieve and display the data on the text area.
However when the content is too large, I am not able to dynamically set the height of the text area. When I try to display the same as a label, the display is flawless, dynamically sets the height as per the content. So, I tried to create a label, with same content and dynamically bind the height to the preferred height as below, but it doesn't work.
// Generate User Note Description
TextArea textArea = new TextArea();
Label text = new Label();
// SETTING THE TEXT TO A LABEL TO RETRIEVE THE HEIGHT
text.setText(usrNotes.getNote().trim());

{

Next to reading I need to assign to two dimensional array, but without giving "col1","col2","col3" a lot.
The array is for example, Array[3][] = {{"c00"},{"c10","c11"},{"c20","c21","c22"}};

I want to disable one of the JMenuItem on load itself but when i tried with following code it is disabling after I selected the JMenuitem.
what additional changes are needed to make it work accordingly.

public void actionPerformed(ActionEvent e) {
applyTruthFlag(currentBTE.isTruthFlag());
}
});
this.menuFilter.add(this.onOffItem);
private void applyTruthFlag(boolean truthAuswertung) {
this.onOffItem.setEnabled(truthAuswertung);
//this.onOffItem.repaint();

I have a website which requires login. After I enter username and password and click login button, a new page is loaded. In that page I have a username in the right up corner. When the user clicks logout button, Session.Clear() method is called and also Response.Redirect(" to login page "). It works OK, but the problem appears when I then click Back button in the browser. It gets me back to previous page with the username in the right up corner. Insted, I would like to show message asking user to enter password again so he can login properly.
What should i do at client side???

View Replies View RelatedI am learning Java but have a strong C# background. I am trying to figure out the syntax to do this in Java. In C# I would do the following to enable all text boxes in a panel
private void EnableAll() {
foreach (Control ctrl in Panel1.Controls) {
if (ctrl is Textbox)
((Textbox)ctrl.Enabled = true;
}
}
Is there something similar I can do in Java to do the same thing.

I have a web application. I want to generate the UI part(basically html/jsp pages) to be generated dynamically using drag and drop of elements.So is there is any way that I can:
1: Have drag and drop of elements in jsps?
2: How I can create and store back the form attributes dynamically?
I am just trying to understand during a drag and drop how can I transfer the actual object instead of just creating a new one. I believe I am close but I cannot nail down where I am going wrong. Here is my code I am using to test this.
First/Main:
Java Code:
package main;
import javax.swing.SwingUtilities;
public class Main {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable(){
[Code] ......
When I drag the JPanels it just copies and makes a new one. I tested this by having a sysout send to the console a private int that I set during the initial creation of the object.
How to calculate an outcome/number through a combination of 4 drop down menus (drop down menu's 1 and 2 combine to form a specific value and menu's 3 and 4 combine to form a specific value), example ;
1st drop down menu (1*) = a,b,c,d,e
2nd drop down menu (2*) = 5,4,3,2,1
3rd drop down menu (3*)= a,b,c,d,e
4th drop down menu (4*)= 5,4,3,2,1
Example of drop down menu layout - [URL] ....
a->e = low to high (value) predominant value so b5>a1 ; d5>c1
5->1 = low to high (value)
Then the calculation involves the 1st and 2nd menu to form 1 value, so c3, e4 etc and the 3rd and 4th menu unite to form 1 value that is different from the first; c2, e3
So (1*2*) b3 ; (3*4*) b1 = x value
Also the value from 1*2* menu must be lower than value from menu 3*4*; so you cannot input 1*2* c4 ; 3*4* c5 /or b1 (so once the first menu is selected, the 3rd and 4th menu's wont show anything lower)...
Is it possible to do drag and drop using robot class instead of using TransferHandler class?
View Replies View RelatedIs there a way to disable sorting by clicking on the JTable headers?I have tried a few ways but because I am sorting the data when I load it that 'breaks' that also. Here is what I am trying to achieve.

table.setAutoCreateRowSorter(true);
table.getRowSorter().toggleSortOrder(6);
table.getRowSorter().toggleSortOrder(7);
table.getRowSorter().toggleSortOrder(5);
table.getRowSorter().toggleSortOrder(5);
but then I want it so the user cannot resort that when the table is displayed..
