Importing image to another class.
In the view controller file.
there is two methods, one is for opening the iphone photo library
and the other one is didFinishPickingImage:editingInfo.
after choosing the image, it will the bring the user to the SomeEdit file with .xib file
in the someEdit file there is a UIImageView already.
but the question is I don't know how to link the two files together.
to show the image in the someEdit interface.
Can anyone tell me what method I should add to let it link together?
Hi,

Problems drawing images form another class
Ok as the title says I'm having trouble drawing images from a different class. I have a class that represents a plane and it has a draw' method that draws its .gif image.
public void draw (Graphics g)
g.drawImage(planepic , xPos, yPos, null)
then in my main class in the paint method i have
plane.draw(g);
I think my problem is the null for my image observer. I tried using null as my image observer and i got a error saying i can't make a static reference to a non static method.
I've done some research because i never really understood static but i still don't quite get it.
Also when I use this as my image observer i get a error in my plane object.
I also just tried passing and making a object for my main class and i still got the static error.
Any help is appreciated and thanks in advanceOk as the title says I'm having trouble drawing

public class Plane implements ImageObserver
public boolean imageUpdate(

switch(infoFlags)
case ALLBITS:
return false;
case SOMEBITS:
return true;

return true;

Any help is appreciated and thanks in advanceWhen you call draw(g) from your other class you hand it a Graphics context that you instantiated somewhere else ie: in another class. Without a more complete example it is really impossible to determine your issue for sure,
but if I was to guess I would say you need to make sure that the Graphics context handed to the draw(Graphics) method was instantiated from a Component that was already visible. ie: Do a f
Frame.createImage() from your parent frame after iyou have already called setVisible(true); In other words I suspect you are making and Image from some other Component that is not yet visible. That however is a guess so if not the issue post the rest of the code or at least a minimal implementation that demonstrates this.
About static:
static means the class/variable is the same throughout ALL classes of that type and if changed in one instance it will change and thus be the same for all instances.
You CAN call static by referencing the base class Object without having to instantiate.
ie:given
public class SomeClass
static String name;
static String getName
if(name == null)
name = "DefaultName";
return name;
}Thus you could call..
String name = SomeClass.getName();As opposed to
SomeClass myClass = new SomeClass();
myClass.getName();This can get you in trouble if you try to make a method that is static
that then tries to reference non static variables.
ie:
public class SomeClass
int x;
static String name;
SomeClass()
x=0;
static String getName
if(name == null)
name = "DefaultName";
x++;
return name;
}In this case SomeClass.getName(); will throw and exception because it is trying to access[b] x from a static context .
Hope that clears that up for you; if not post a more complete example.
Good Luck!

Cannot import custom made java class
Hello
I wrote a java class say (Money.java) which compiled fine. When I was importing it to another class (Account.java), the folowing error message appears:
Account.java.1:'.' expected
import Money;(an errow pointing to ";")
I dont think the code is wrong, because when I cut and attach the Money class code to the front of the Account class it compiled successfully.... I am confused! I wrote the import command according to the text book as follows:
import Money;
public class Account
By the way, both the Money and Account classes are saved in the save folder... How come it wont let me import...
Looking forward for an early reply.
ThanksIn older versions of Java, it was possible to import classes from the default package using a statement like:
import Money;
This feature has been removed from Java as of version 1.5. You cannot import classes from the default package.
Note that if your other code (Account.java) is also in the default package, you do not need to import the class Money. Just remove the import statement.
If class Account is in a different package and you want to use class Money, then the only option you have is to put class Money in another package than the default (unnamed) package. -
Class fails to import another class in J2SE1.4?Why?
Dear experts,
I use JSDK1.4.2.
I havenot set any classpath.
I write the following two classes.
class1.java
public class1{
public class1(){
public void showMessage(){
System.out.println("Message from class1");
I have another class "class2.java" with the following code:
import class1;
public class2{
public static void main(String arg[]){
class1 clsObj = new class1();
clsobj.showMessage();
I have stored both the classes under c:\MyFolder.
I havenot used any package and i donot want to use packages.
when I compile "class1.java" in the C:\MyFolder> , Its compiled without any problem.
But when I try to compile the second class "class2.java",It shows the error at the line
"import class1", '. expected'
Though I can use the class1 as it is without importing it into class2.java, I used this as an example to solve some other problem.
What could be wrong? Should I set the classpath?
Please help me to resolve this.
Thankx in advanceThis line does not look very pretty:
public class1 {Try this instead:
public class class1 { -
Is there a way to click on one image and activate the animation in another class?
I'm using the ibooks.js library. So it'd need to .activate another class if using the ibooks-toggleable function.
Thanks!Harold,
I can't say how this compares to Word, since I don't use it, but you can open as many document at a time as you wish in Pages. Each will have its own window. Having too many open will slow your system and reduce Macbook battery life.

Calling a class's method from another class
Hi, i would like to know if it's possible to call a Class's method and get it's return from another Class. This first Class doesn't extend the second. I've got a Choice on this first class and depending on what is selected, i want to draw a image on the second class witch is a Panel extended. I put the control "if" on the paint() method of the second class witch is called from the first by the repaint() (first_class.repaint()) on itemStateChanged(). Thankx 4 your help. I'm stuck with this.This program is for my postgraduation final project and i'm very late....

Problem using repaint() method from another class

Needed help in: how to import image in InDesign Server using Java Code
New to InDesign Server.
I am not been able to import image to document.
I tried to import image using the sample snippets "PlaceTextFileInFrame.java".
modified the line:
String placefilepath = "C:\\placeFile.txt";
to
String placefilepath = "C:\\Image.jpg";
myTextFrame.place(placefilepath);
Is this the correct way to import image or there is another solution.
1.The image gets imported but i am getting blur image(Zoomed image).
2.The image gets imported to its original image width & height.
3.I need to know how to set the image width & size.My Requirement is-- I ve to connect to msn search page in order retrieve the result set from msn search. The same code which I do pasted below is working for GOOGLE n YAHOO with minor changes.But not for MSN.., Can any one help me.
I've pasted the code for msn..,

Adding a MeshView as part of another class not working when returned?
I have a class that extends box, to get the properties to display it as a box, or else have the option to display it as a 3D image/Mesh.
I have this code
public class Face extends Box
private MeshView image3D;
public Face(TriangleMesh mesh)
this.image3D = new MeshView(mesh);
public TriangleMesh getImage3D()
return (TriangleMesh) image3D.getMesh();
public MeshView getImage3DView()
return image3D;
public void setImage3D(TriangleMesh mesh)
this.image3D = new MeshView(mesh);
Granted there are many more methods and variables I just wanted to show what I needed. Basically I have a 3D importer class, which I'll post in a second, which imports the data for the mesh. From there I return the TriangleMesh and then set it to a MeshViewer that is setup currently as a constructor call in the Face class, and then I set it to a group using the getter method.
Face d = new Face(i.stlImporter("CylinderHead-binary.stl"));
d.setMaterial(gray);
d.setLayoutX(200);
d.setLayoutY(200);
Group s1 = new Group (d.getImage3DView());and finally
public class importer
TriangleMesh mesh = new TriangleMesh();
public TriangleMesh stlImporter(String s)
StlMeshImporter stl = new StlMeshImporter();
// Generated vertex normals result in a smoothly shaded surface
stl.setCreaseAngle(24);
try
URL cylinderHeadUrl = this.getClass().getResource(s);
stl.read(cylinderHeadUrl);
catch (ImportException e) {
e.printStackTrace();
// STL includes only geometry data
mesh = stl.getImport();
stl.close();
return mesh;
public TriangleMesh getStlImport()
return mesh;
}However if I change all of the face code into MeshView it will work. So basically it seems that something is up with MeshView being used in Face.
Edited by: KonradZuse on Apr 5, 2013 8:22 PMWell basically I wanted to have a class that was originally a box, but then would have a 3D image. The converter that came out a week or so ago imports it as a Mesh, so I wanted to be able to have it return a mesh if it's a 3D object.
I was just confused how it would all work. To make a box, I assumed I had to extend the box, and great it based on that, or shape. Maybe it would just be easier to save the TriangleMesh, then load it into a MeshViewer in another class. I figured I could just make a viewer in the class and just add that viewer, but maybe that's not a good idea.
Now I realize that I can just make everything a 3D mesh, box included, so I can just make it a viewer with additional properties like my box was supposed to be, or maybe just the mesh itself, then add it to a viewer later, thoughts?
I'd appreciate any insight on the class structure that I'm confused about, thanks!~!!

Problem getting arraylist from another class
I am trying to call information about an arraylist from another class. I am using this code to call the size of an arraylist:
import java.io.*;
public class Test
public static void main(String argv[]) throws IOException
Echo03 thing = new Echo03();
int y=thing.value();
System.out.println(y);
Echo03 thing2 = new Echo03();
int x=thing2.percent.size();
System.out.println(x);
}from another file which starts like this:
public class Echo03 extends DefaultHandler
static ArrayList<String> percent = new ArrayList<String>();
static ArrayList<String> text = new ArrayList<String>();
int a;
public int value(){
return percent.size();
public static void main(String argv[]) throws IOException
{The second file is based on an example piece of code from the Java website. I havent posted the whole thing, but if it is relevant then please ask.
Anyway when I run Echo03 by itself, the arraylist has a size of 2. But when I run it from the Test file, it says a size of 0. Is this because the data is not being transferred between the classes? Or is the Echo03 program not executing (and hence the arraylist is not filling up)?
How can I fix this? I have tried 2 ways of calling the data (As seen in my Test file). Neither work.I didnt post the full bit of the code for the second one. Here it is:
import java.io.*;

int a;
public static void main(String argv[]) throws IOException
if (argv.length != 1) {
System.err.println("Usage: cmd filename");
System.exit(1);
// Use an instance of ourselves as the SAX event handler
DefaultHandler handler = new Echo03();
// Use the default (non-validating) parser
SAXParserFactory factory = SAXParserFactory.newInstance();
try {
// Set up output stream
out = new OutputStreamWriter(System.out, "UTF8");
// Parse the input
SAXParser saxParser = factory.newSAXParser();
saxParser.parse( new File(argv[0]), handler);
for (int b=0; b<percent.size();b++){
System.out.println(percent.get(b+1));
} catch (Throwable t) {
System.exit(0);
static private Writer out;
public void startElement(String namespaceURI,
String lName, // local name
String qName, // qualified name

throws SAXException
if (attrs != null) {
StringBuffer sb = new StringBuffer (250);
for (int i = 0; i < attrs.getLength(); i++) {
nl();
emit(attrs.getValue(i));
sb.append (attrs.getValue(i));
String sf = sb.toString ();
percent.add(sf);
System.out.println(" String: "+sf); a++;
public void characters(char buf[], int offset, int len)
throws SAXException
emit(" ");
String s = new String(buf, offset, len);
if (!s.trim().equals("")) {text.add(s); emit(s);}

Easy question: Give access to a class in another class.
Stupid title, but dont know how to express myself :P Sorry for that.
To the problem. Never had this problem before, and I know its a really easy solution to this.
I have my Main class, which creates a MyView class. Inside this class, I make to new classes(or instances of classes i've already made), MyPanel and MyToolsPanel. Now I want to add buttons inside the MyToolsPanel class, and add actionlisteners to these buttons inside MyPanel.
What I'v always done to grant access to MyToolsPanel inside of MyTools, is to simply add a
//this is the MyPanel class
MyToolsPanel mtp;
public void setMtp(MyToolsPanel mtp){
this.mtp = mtp;
}and then in the MyView class which create these to classes, I put a command: mp.setMtp(mtp);
When I run this it doesnt work.. Why? Should be easy to solve, since it obviously is a stupid problem that I just dont see. :P Feeling kind of stupid to ask this question, but this is how it is...
EDIT: I might have to implement actionListener inside the MyToolsPanel class?

Unable to add/import images from other sources
Hi,
I'm using iPhoto 5.0.4, and I'm trying to import images that were captured on another Mac using iPhoto 2 and then burned to CD so that I could take them home. When I go to "Add to Library", it tells me that iPhoto could not import the files because they may not contain valid data or it may be an unrecognized file type. The file type is the same. Whether it's valid data or not is impossible for me to interpret since the pics open up in any image editing program just fine.
Any suggestions or work arounds?
SophieHi Sophie,
Where are the images that you are trying to add to the library?
did you put them in the iPhoto Library folder in the Finder manually?
If you did, drag them to the desktop, then add them to the library. -
How to exchange one image for another with a click
I am brand new to actionscript, so bear with me! I need to create an interactive web-based system which takes the user through steps to assemble something. One of the pages will have images of the tools needed. I want the user to be able to 'tick' off each tool, so that when they click on the image of a specific tool it is replaced by the image faded out and a big red tick over it. essentially it is replacing one image for another when it is clicked on.
any ideas on the actionscript? Sorry i know this must be basic stuff for you!
thanks!your tool images should be converted to movieclips and given instance names and you should create a red tick movieclip that you assign a class, say RedTick. you can then use:
tool1.addEventListener(MouseEvent.CLICK,toolClickF);
function toolClickF(e:MouseEvent):void{
var redtick:RedTick=new RedTick();
addChild(redtick);
redtick.x=e.currentTarget.x;
redtick.y=e.currentTarget.y;
e.currentTarget.alpha=.4; -
"Imported" images are on disk but show up as grey rectangles in Lightroom 4 and 5
All of a sudden, images "imported" into Lightroom 4 started showing up only as gray rectangles. The first set of images on the card had been "imported" with no issues. The second set of uploads (different images) have always shown up as gray rectangles (from the first "import"). Same result when I removed the Lightroom folder and used a card reader instead of straight from the camera. I tried images from another card in another camera and got the same result, so it seems like a software issue. In hopes of fixing the problem, I upgraded to Lightroom 5 (it was time anyway). But the upgrade of the original Lightroom 4 catalog to a Lightroom 5 catalog did not solve the problem. Based on my research on this site, I trashed and replaced my Preferences file but everything remains gray rectangles. Any ideas would be greatly appreciated.
First thing to try is to recalibrate your display. This is often caused by a bad display profile. Second thing is to delete the previews on your images and have Lightroom rebuild them.
