java - How to make endless (infinite) nodes in Piccolo2D? -


I would like to draw some infinite objects in Piccolo2D, such as endless rectangular (cartesian) grid. It will be indifferent in the graphic editor on the grid as some geometrical object.

Unfortunately, Piccolo determines some kind, even if the color needs to be called and it does not apply to me appropriately.

The program below has yellow objects, which I want to make endless. This type is Pendles . I am adding this cycle as a child. 

  Package test. Endless; Import java.awt.color; Import java.awt.geom.Rectangle2D; Import org.piccolo2d.PNode; Import org.piccolo2d.extras.PFrame; Import org.piccolo2d.nodes.PPath; Import org.piccolo2d.util.PPaintContext; The public class Try_PGrid {public static class PENDless PNode extends {@Override protected void paint (PPaintContext paintContext)} (rectangle 2D localclip = paint contact. Tolkoclip (); . PaintContext.getGraphics () setColor (Color.yellow); fill colorContext.getGraphics () filling (localClip). }} Public Static Zero Main (string [] Args) {New Peephr () {@ Override Public Zero Starter () {PPath circle = PPath.createEllipse (0, 0, 100, 100); Pendalece grid = new pandale (); grid.addChild (cycle); //grid.setBounds (Double.NEGATIVE_INFINITY, double. NEGATIVE_INFINITY, double .POSITIVE_INFINITY, double.POSITIVE_INFINITY); // do not work on all //grid.setBounds (10, -10, 50, 50); // Yellow until that grid grid Setbound (-1000, -1000, 2000, 2000); // until the extent of pigeon (yellow) GetLayer () AddBild (grid); }}; Unfortunately, I have found that:  
 1) If the limitations are the default (empty) then the yellow paint only happens when the circle is visible  
 2) If the limitations Large and finite, so the yellow paint with the border  
 3) It does not support the infinite couple, although it is legal in theory; If there is infinite set, no one is attracted to it.  
 How to implement?   
 
 
 This is a part of how Java handles drawing.

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...
