java - GUI doesn't display the background i set for it(compiles) -


I am trying to create a GUI to make a game, this game is irrelevant.

According to me, what I should do is show me a GUI, with one frame, however, only shows the frame, the image is not found anywhere: (

Does anyone tell me Could I have done wrong? Thank you for your time! javax.swing.jframe; import javax.swing.jpanel; import javax.swing.ImageIcon; import javax.swing.JLabel ; Import Javax.swing. *; Import java.awt.BorderLayout; import java.awt. *; Public class graph {int maxX, maxY; personal jframe frame; graph () {dimension screenSize = toolkit.getDefaultToolkit (). GetScreenSize (); MaxX = screenSize.width; maxY = screenSize.height; frame = new JFrame ("My application"); Frame.Set default close operation (JFrame.EXIT_ON_CLOSE); Frame.Set Size (Max, Max); Frame.Setlines SerialTit (Empty); JLabel label = new jlab (icon), zpnic panel = new zpinal (new border layout); panel.ed (la bell, border layout.c.ca); frame.add (panel, BorderLayout.CENTER); frame.setVisible (true);} public string (g) {return.getClass (). GetProtectionDomain (). GetCodeSource () GetLocation (). GetPath () ReplaceAll ("20", ""); } Public static zero major (string algos []) {SwingUtilities.invokeLater (new runall) {@Override Public run zero () {GraphG = new graph ();}}); }}

This example shows you the correct order in which you want to perform operations . In addition, the SwingUtilities.invokeLater () method should start a swing application. It uses EDT, which you can read, another note is that you set the size of the frame, but when it shows that it is too small, the reason is that you have created the frame.pack ( ) , which will ensure that only the location you really need is used. 

  import java.awt.BorderLayout; Import javax.swing.JFrame; Import javax.swing.JLabel; Import javax.swing.JPanel; Public class graph {JFrame frame; Public Graph () {frames = new JFrame ("My Applications"); Frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE); Frame.setSize (1366770); Frame.setLocationRelativeTo (zero); JAlabelLabel = New JLab ("Some Labels"); Jpegel panel = new zpinal (new border layout ()); Panel.ed (label, border layout.ca); frame.add (panel, BorderLayout.CENTER); Frame.pack (); Frame.setVisible (true); } Public static zero major (string algos []) {SwingUtilities.invokeLater (new runall) {@Override Public run zero () {GraphG = new graph ();}}); }}

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
