I have a colour coded table, the JComboBox has items that are also colour coded to correspond to the colours on the table.
My ComboBox contains:
comboBoxSFMotor.addItem("Select a Value");
comboBoxSFMotor.addItem("Electric");
comboBoxSFMotor.addItem("DC Shunt");
comboBoxSFMotor.addItem("Combustion");
How can I set a background colour for each of the items in the JComboBox that will correspond to the table so that the user can make an easy selection?
I am creating a JSP page with a html table to display employee directory. This is scriptlet :
<% List<Employee> list = new ArrayList<Employee>(); PhoneListController controller = new PhoneListController(); list = controller.getAllContacts(); for (Employee eachEmp : list) { %>
and then i display the table rows and columns for each employee object(PS: I know scriptlets are bad and obsolete but this is my first individual project.)
I would like to change the background color of certain rows based on value of one particular value(based on eachEmp.getManagerCode).
How can i achieve that by using javascript? I tried to call a js function by calling onload event on . But as I need to check for each row that is not the possible solution. I have not tried jquery yet as I am very new to jquery and I didnt quite understand how to do it in jquery.
I have code which query value from database,the use case is the user can enter value as 1,01,11 in database but when the user enter value in xml file he can only enter 11,01,12 in database there is two columns lets say column test1=1 and test2=2 combination of this is 12,which is the value the use will enter in xml, but sometime the use can enter test1=04 than column test2=00 ....
I need to display a list of environment id's out of my xml file into a JComboBox. I understand fine how to make lists and what not but examples are always hard coded.
No problem setting background color for layouts, e.g. bdrPn.setBackground(new Background((new BackgroundFill(Color.BLACK, CornerRadii.EMPTY, Insets.EMPTY))));
But neither of the following are working for me, running JavaFX 8 on latest OS-X
scene = new Scene(bdrPn, winW, winH, Color.BLACK); scene.setFill(Color.BLACK); scene.setFill() worked fine for previous versions of JavaFX.
I've just started working on a program and i'm already having difficulties with the program. I can't get the background color to change from the basic gray color. Maybe you can tell me what i'm doing wrong.
import javax.swing.JFrame; import javax.swing.WindowConstants; import java.awt.*; import java.lang.Object; import java.awt.Color; public class FrameDemo{ public static void main(String args[]){ Toolkit toolkit = Toolkit.getDefaultToolkit ();
[Code]...
also if theres any way to shorten up what I have there, that would be great.
If I want to read from file the word "red" And then the following is not the right way like in the code ,, How to set the Color name
File inputFile = new File ("C:\input.txt"); Scanner scan = new Scanner (inputFile); String RedColor=scan.nextLine(); Color backColor = new Color(redColor);
I need to process one component drag to the table. I misunderstand, how I can see to which Cell fall the component. I tried to use Event and Mouse event handlers in my custom Cell, but they do not work. I can copy the drag event to the table and table handles it, but how to get needed Cell I cant understand.
I am trying to align the core/middle side color of a cube, index 4, with the bottom middle color of the same side, index 7. (Each side has values 0-8 where 0 - is the top left corner, 1 is the top mid corner, 2 is the top right corner, 3 is the middle left corner, etc).
In addition to lining up those two colors, I am also making sure that the neighbor color of index 7(the color that it is attached), in this case the bottom color, matches with the top core/middle color. I will attach some pictures and a print out to show what I am talking about...
However, in my code when I am trying to align all of these up together, it does not go into the while loop. Each of the loops essentially is trying to get a match of same color with index 4 and 7, as well as making sure that index 7's neighbor color (the bottom color, in this case) matches with the top color.
Here is what I have tried:
private void alignSideColor(){//make the bottom colors neighbor match with a middle side value and rotate it to the top, for the top cross
if(cube.bottom.square[1].charAt(0) == topColor){ while(cube.front.square[7].charAt(0) != frontColor && cube.bottom.square[1].charAt(0) != topColor){ rotateBottomClockwise(1); System.out.println("Trying to align side color...");
[Code] .....
The print out of the ELSE IF is: alignment is: W-G and tops: R-R NOW ITS ALIGNED even though the sides, index 4 and 7, are NOT aligned with each other
I have also tried the same thing but with out the 2nd condition in each while loop, and although is DOES enter the while loop, it does not perform correctly -- index 4 and 7 WILL have matches colors, but it does not check to see if index 7's neighbor matches with the top color.
Here is how it prints out ** ** ** G7 B6 Y1 ** ** **//this portion is the back of the cube ** ** ** R6 W5 O4 ** ** ** ** ** ** R3 W2 O1 ** ** ** B3 G4 Y9 W9 O8 Y7 W3 B4 G9//this portion is the left, top, and right of the cube B2 G5 R8 W4 R5 Y6 O2 B5 G8 O7 W8 R9 B7 B8 B9 R1 R4 R7 ** ** ** O3 O6 O9 ** ** **//this portion is the front of the cube ** ** ** Y2 Y5 Y8 ** ** ** ** ** ** B1 G6 W7 ** ** ** ** ** ** Y3 Y4 G1 ** ** **//this portion is the bottom the cube ** ** ** R2 O5 G2 ** ** ** ** ** ** W1 W6 G3 ** ** **
Here is the cube showing the top, left and front side
Here is the left and bottom side. As you can see index 4, G5 -- yes that is a 5 lol -- does not have the same color as index 7, W8.
I need to rotate the bottom until W8 is aligned with a middle white value. An examples of a neighbor is: W8-R2
This is my codes in a button that if I click it . that information will send to Jtable but the problem is the jtable is in another frame so how can i connect this ?
DefaultTableModel model = (DefaultTableModel) new admin().tableBagtags.getModel(); if (txtName.getText().equals("")) { JOptionPane.showMessageDialog(null, "Please fill out all fields.", "Error!", JOptionPane.ERROR_MESSAGE);
I'm trying to get the input of two jcomboBoxes for example if jcombobox 1 option 1 and jcombox box 2 option 1 is selected result = x
Here is my code:
comboDest1.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent event) { // // Get the source of the component, which is our combo box. // JComboBox comboDest1 = (JComboBox) event.getSource();
So why is it that when I attach a KeyAdapter to a JTextField the code in the KeyAdapter will execute, but when I apply that same KeyAdapter to a JComboBox with its edit feature turned on it won't and, more importantly,
displaying COM port in Combo box , see my code below , it does not show any error but it does not show COM port in combo box , instead it shows the class name of Communicator with some garbage data .
I am trying to Make A GUI which has a Jcombo box i also want it to have a jlabel that up dates depending on which option the user selects from the JcomboBox
for exampl if i select lion i want it to say you chose lion on the Jlabel and if i choose ostrich i want it to say ostrich and so on
CommPortIdentifier portIdentifier = CommPortIdentifier.getPortIdentifier(port); if (portIdentifier.isCurrentlyOwned()) { System.out.println("Error: Port is currently in use"); } else { CommPort commPort = portIdentifier.open(this.getClass().getName(), 2000);
[Code].....
To set the serial port parameters i need to use Integers instead of strings.
I'm having an issue with using a JComboBox to select an item from a parallel array and displaying the correlating results in the same frame. Essentially, I have to add seven cities to a JComboBox drop down within a frame, select a city then display the population of that city in the frame with a label indicating the population. I have two issues:
1) my label text will not show up during execution unless I drag a corner no matter what width or height I make the frame.
2) I need to make the JComboBox selection correlate to the city population and display as a label, not having making that work using the getSelectedIndex() method.
I think I need to add an event listener for the combobox selection, not sure where to add that if that is the case. Here is my mess so far:
I have loaded the combo box at starting of program.When i am adding the element to combo box through database it's not updating visually.But the inserted data is successfully loaded in List.
I'm trying to populate my JComboBox with an Arraylist. Using two different classes, a GUI class (with the JComboBox - called it MainGui) and a class where I extract information from a database and put it into an ArrayList (which I call databaseconn).In my databaseconn class, I can print out the content of the ArrayList perfectly fine, but when I try to do it in my GUI class it just prints empty brackets "[]".(What I need it to do is to populate the drop down list in the JComboBox with the hotel information).Here's my code:
//The dataaccesslayer you should use for classes that deal with connection to the database

Can a JCalendar be used as an item. I cannot find and appropriate combodatepicker or at least one that looks like a standard combobox. I cannot get an answer from google search all i can get is how to add normal items.
I recently posted that JComboBox should be used in a generic manner. I presumed that once declared, with some type Foo, that one could then do:
Java Code:
JComboxBox<Foo> cb = new JComboBox<>(); // sometime later Foo foo = cb.getSelectedItem(); mh_sh_highlight_all('java');
However, getSelectedItem() is documented to return a type of Object so a cast is still needed. I can't understand (even for backward compatibility) why it doesn't return a type of the specified type. Many other old classes have been converted to generics so why should this be any different? I just found that one could use getPrototypeDisplayValue() but that seems counter intuitive.
My database contains path of images that I want my jComboBox to diaplay. I have written the following code but it does not work for comboBox but works fine when I display image on jLabel etc. How should I go about this
The program to actually read what i am entering inside the comboboxes. It is all there but does not work when i hit the submit purchase button.
import java.util.*; class DateConstructor { /* Verifies that the day code is consistent with monthCode and yearCode. Returns the corresponding date if so. If not, it sets the errorCode to an appropriate value and returns null. */ public static Date constructDate(int monthCode, int dayCode, int yearCode, ErrorCode errorCode) { boolean isCorrect = false; Date dateEntered = null; switch (monthCode)
I have a student class with fields names and Gender. Now, I have a students' array. such that I can create multiple students' classes: student a, student b, student c e.t.c and store them into the students' array. Now, I store this students' array in a JComboBox and want to only display the names of these students in the array. Such that the JComboBox lists only the names of student a, student b and student c. . When a user clicks on a selected Item on the JComboBox, even though, it was a student's name that was selected, I want the selectedItem to be a object of the Student class. This, I have learnt works with JList by writing your own custom JList models and then DefaultListCellRenderer. Is there anyway, one could also do this with JComboBox?
//Main Method import StudentList; import Student; import ViewGui; import Controller; public class SwingMainMethod {
