Java App - Capture Selected Area Of Screen And Save It
Oct 22, 2014
I want to do an app that capture a selected area of a screen and save it. I did a few research and i did the code down below.
My questions are:
1 - How can i open a pdf file in this app ? (i tried use a method but it didnt work. I dont know exactly where to put it on the code)
2 - How can i save the selected area in a new file ? (a image file : JPEG, JPG,png)
3 - [the complex part] right now, the code only "save" one selected area each time. I want to capture a lot of parts of screen and save this in the same image file. one beside the other. How can i do this ?
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.

I'm making a game of checkers for my A2 Computing coursework which is due in within a week. I have completely finished the game, and only thing I have left to do is connect the two JPanels together via a CardLayout that I have made. However I am unsure how to do so
I have kept the code I am displaying to a minimal, hence I have removed all the action listeners for my buttons, anyway the problem I have is that, I would like it so that when the user clicks on the 'Multiplayer' button which is the array button ourButtons[1], it will then transition into my main game screen so that the user can then play a game of checkers.
Here is the main important GUI from my CheckerBoard class:
import java.awt.*; import java.awt.event.*; import javax.swing.*; public class CheckerBoard extends JPanel implements ActionListener, MouseListener { // Main routine that opens an Applet that shows a CheckerBoard public static void main(String[] args) { new CLayout();
I've been having trouble with this code for about a week and I've finally got it down to one error. Here is the code:
import java.util.Scanner; public class Triangle { public static void main (String[] args) { Scanner Console = new Scanner(System.in); System.out.print("Please enter the three lengths of your Triangle: "); double a = console.nextDouble();
[Code] ....
And here is the error:
Triangle.java:30: error: class, interface, or enum expected } // End class ^ 1 error

I'm currently writing a small program, where I need to save data into a Defaulttablemodel in a jTable.I have to save the name, a number and the email-adress.I added a button which opens a new JFrame and there I need to change the email and/or the name.My current solution is far from good: No matter which row I select, i can only update the "newest" row (last created). How can I visualize the values of the selected row (out.println// or whatever) so I can go further and overwrite these values.My Code when I click on Update:
int zeilenwahl = jTableStudenttab.getSelectedRow(); // System.out.println(jTableStudenttab.getSelectedRow()); if (zeilenwahl != -1) { this.setVisible(false); new Bearbeitung().setVisible(true); } else { JOptionPane.showMessageDialog(rootPane, "Zum Bearbeiten Zeile auswählen"); }

I just learned about 2D arrays and am still trying to get a grasp on the concepts. I'm a little confused by how you return all the values in a row to add up and display the sum if the row is entered by the user.
import java.util.*; public class RowSum { public static void main(String[] args) { Scanner s = new Scanner (System.in); int userpick = 0; int sum = 0;
