Determining if printing is going on in paint method
By looking at the source of the existing visual components, I have found out that JComponent.paintChildren uses getFlag(IS_PRINTING) to determine wether or not the current call to paint will paint to screen or to a printer.
The problem is that both getFlag and the constants it uses are declared as private in JComponent. This is why I am wondering why Sun chose to keep this information private to the JComponent class, while this information could be very useful in some situations.
Also, would there be any alternatives to determine wether or not printing is occuring from a paint method besides managing flags the same way JComponent does?
Thanks in advance.
I gave a try to your approach but it doesn't seem that the graphics object passed to the paint method during the printing process implements PrintGraphics. I'll keep trying stuff with that idea until some new input is given, but thanks for the idea, it sure could have worked out ;)

Output determination and Printer determination for both PO and GR
Dear all,
Can anyone please help me in congiguring the output determination and printer determination for both PO and GR. please give me detailed configuration including the paths as i am stuck with the configuration.
Thanks & Warm Regards

Output of Purchase Order
1. Condition Table
SPRO > Material Management> Purchasing -> Message -> Output Control->Condition Tables->Define Condition Table for Purchase Order
Select:
Purchasing Doc. Type,
Purch. Organization,
Vendor
2. Access Sequences
SPRO -> Material Management-> Purchasing -> Message -> Output Control->Access Sequences->Define Condition Table for Purchase Order
3. Message Type
SPRO -> Material Management-> Purchasing -> Message -> Output Control->Message Types->Define Message Type for Purchase Order
*4. Message Determination Schemas*
4.1. Message Determination Schemas
SPRO -> Material Management-> Purchasing -> Message -> Output Control->Message Schema->Define Message Schema for Purchase Order-> Maintain Message Determination Schema
4.2. Assign Schema to Purchase Order
SPRO -> Material Management-> Purchasing -> Message -> Output Control->Message Schema->Define Message Schema for Purchase Order-> Assign Schema to Purchase Order
5. Partner Roles per Message Type
SPRO -> Material Management-> Purchasing -> Message -> Output Control-> Partner Roles per Message Type ->Define Partner Role for Purchase Order
6. Condition Record
Navigation Path: SAP Menu-> Logistics -> Material Management -> Purchasing-> Master data->Messages-> Purchase Order-> MN04-> Create
Now you create PO (ME21N) and save it. Go to ME22N and print the PO by giving output type.
Output of GR
After setting table, access sequence and output type for GR,run MB02 transaction, enter material document number. Double click one line item and select messages. Separate screen will be opened to configure outputs. Give the required fields and save the document. Now Run MB90, you can take printout. Output Type: WE03 or WE01 or WE02

I cannot print any websites; every time I press "print" it goes to "save the file as [xps]" instead. What's up? I can print in Word without problem.
Bless you, bless you, bless you. After months of living with this annoying problem and not being able to print out emails or websites it is, in a stroke, totally solved. Thank you! It works. It's a wonder and you're a winner!

How do I set up to print from my iPad directly to a "wi-fi direct" printer WITHOUT going through my household wi-fi network/modem? I want to get rid of my household internet service/modem and only use my iPad, but need to be able to print. Please help! Thank you!
Depending on the printer, you may be able to connect/print by creating an ad-hoc (Wi-Fi direct with no router) connection. Check with your printer manufacturer to see if this is supported.
There's a ton of info out there. You could google "ipad print ad-hoc" for some useful info. But the number one thing for you right now is to verify that your printer model supports an ad-hoc connection. -
I want to buy an hp m1536 laserjet for my ipad printing, I believe the printer is not wireless but has sprint. Is the print job going through my wireless router and does that router need to support AirPrint.
The following model is airprint compatible, is this the one you have?
HP LaserJet Pro M1536dnf MFP
If not the "dnf MFP" model, then no.
The router needs to support the Bonjour protocol. If not, the airprint won't work. -
My wireless printer keeps going offline--how can I "stabilize" the connection"
my wireless printer keeps going offline--how can I "stabilize" the connection?
This question was solved.
View Solution.Hello gerrie,
What i would do is Power cycle the printer and the router as well
-basically having them turned off for about 10-15 seconds
-and then powering back the router back on wait for all the lights to turn on completely
-and after that is back up and running i would turn the printer back on and re-establish the connection between the printer and the Wireless network
I am an HP employee.

Passing Data to a Paint Method
Total newbie here just learning the basics of Java on my own. Working a little application that will display a filled polygon which shows the correct heading of ship based on previously input Ship Heading, length and width. I have the application working fine to generate the 5 points, and then it will display correctly when I enter the points in the paint method by hand. Thing is I want to have the coords passed to the paint method. and am having some trouble doing this. All the examples I have seen show the points to be displayed already being declared in the paint method. Here is the Paint Method I have come up with based on examples I have seen. Still pretty new and trying to read through the APIs and other books, but haven't broken the code on understanding them.

Over-riding the paint() method
I want to create a custom button-rounded sides with straight top and bottom to be exact. I understand that you can use the Component class to create components, and over-ride the paint() method to create the actual button's appearance, but how do you do this? Also how do you go about creating an actionlistener for a component like my button idea? Any help will be appreciated!
Since you are creating your own JButton you want to implement MouseListener so that you can detect the mouse up and mouse down events. If you are going to have a hover image then you want to implement MouseMotionListener as well. Here is an example:
public class MyButton extends JComponent implement MouseListener, MouseMotionListener {
private Vector listeners = new Vector();
public MyButton() {
addMouseListener(this);
addMouseMotionListener(this);
public void addActionListener(ActionListener al) {
listeners.add(al);
public void removeActionListener(ActionListener al) {
listeners.remove(al);
//add the overridden methods from MouseListener, MouseMotionListener
public void paint(Graphics g) {
//paint based on the events
}This class will be notified when the mouse enters, exits, is clicked, etc. and you can set a state variable so that your paint routine knows what image to paint.
Hopefully this will clear it up. Not sure how I can make it clearer. -
Help with 2D Graphics - How do I send Variable data to paint method?
I am working on a program that figures mortgage payments and an amortization schedule when a user inputs the principle, APR, and term length in years. After it figures all of those, I want to be able to display a chart that shows the principle and interest amounts for each year. My problem is, how do I get my loan information into my paint method so that I can draw a chart using that data? Any help would be greatly appreciated. The graph class in the code below is called after pressing a "Display Graph" button from my GUI.
I'm pasting my code below. This does not include my main method or my GUI method. I can post those if necessary. Here is my code so far:

My email address iss [email protected] if you wish to reply privately. I can send my entire program code if that will help. Thanks!Hi Deca,
You can use the CmdExecuteSync method of the DIAdem.TOCommand interface to set the value of a text channel. For example passing the string "CHT(1,1) := 'test'" as a parameter to the CmdExecuteSync method will set the 1st row of the 1st channel to "test". Please refer to the DIAdem help for more documentation on the CHT function.
I hope this helps! Please post back if I wasn't clear enough in explaining how to do this or if you have any problems getting it to work.

Hi
I'm working on a draughts game and to make it a little nicer looking I've used graphics for the board squares.
My paint method is double buffered so when a peice is dragged it lags a little because it has to buffer so many images. The only images I need to buffer are the ones that move i.e. the draughts.
Is there a way to draw the squares in a separate paint method so they don't get buffered? Or is java limited to one paint method per class?It's going to lag no matter how many paint methods you use. (Thats even if there ARE other paint methods) If it's lagging because of how many images must be drawn, then perhaps you should write an algorithm that repaints only the areas that have changed. ie: Only repaint wherever the single peice is moved.

How is paint() method invoked?
Hi
I know this may be a silly question but I am not able to understand this concept. I have gone through some concepts of Graphics in Java and some example programs but I am not able to understand what invokes Paint(Graphics g) method. As I dont get this, I am not able to write a program where if I press a Draw button, it draws a line.
I also went through the following link "http://java.sun.com/docs/books/tutorial/2d/overview/index.html" but I did not get my answer.
Please help me.
lakkiSwing determines when a component needs to be repainted. It has a class called the RepaintManager which manages this. You can force the repainting of a component by using the repaint() method.
You should never override the paint() method. Custom painting should be done by overriding the paintComponent() method in Swing. Read the Swing tutorial on "Custom Painting":

Adding a JButton when there's a paint method
I'm creating a game application, sort of like a maze, and I want to add buttons to the levelOne panel to be able to move around the maze. When I add the buttons to the panel they don't appear, I assume the paint method is the reason for this. here's my code, I have 3 files, ill post the user_interface, and the levels class, where the level is created and where i tried to add the button. I tried putting the buttons in a JOptionPane, but then my JMenu wouldn't work at the same time the OptionPane was opened. If anyone knows a way around this instead, please let me know. I also tried using a separate class with a paintComponent method in it, and then adding the button (saw on a forum, not sure if it was this one), but that didn't work either. Also, if there is a way just to simply have the user press the directional keys on the keyboard and have the program perform a certain function when certain keys are pressed, I'd like to know, as that would solve my whole problem. Thanks.

}i tried adding a keylistener, that didn't work too well, i had tried to add it to a button and a textarea which i added to the 'one' frame, it didn't show up, and it didn't work. How would i go about changing the paint method so that it doesn't contain any logic? That's the only way I could think of getting the program to move forward in the game. Thanks.

I'd like to select print paper size with using AxAcroPDFLib method depend on user
I'd like to select print paper size with using AxAcroPDFLib method depend on user
request. Is it possible? in AxAcroPDFLib?
Is there any method to select print paper size in the C# programming.
Or if you know another method, please introduce how to use.
Thank you for your cooperation always.I am pretty sure that you can only do this from JavaScript or from C/C++ APIs.

Paint() method in an entity class
Hi,
I am trying to draw 2 shapes in a Canvas, one rectangle and a circle.
However, I have an entity class for both the rectangle and the circle, something like:
public class MyRectangle
private int width, height;
public MyRectangle() { ... }
pulbic getWidth() { return width; }
pulbic getHeight() { return Height; }
I do not want to draw these 2 shape in the paint() method of the Canvas, I want my Rectangle class and my Circle to have their own paint method to draw themselves into the canvas, is it possible?
If it is possible, can you tell me roughly how to do it?
Do I have to extend the Component class?
Thanks in advance.
SKHi,
I tried to do what you mentioned as the following, but I cant get the circle display on the screen, do you know why? Thanks
