• Printing python tkinter output

  - by Eric

  I am trying to print the contents of a python tkinter canvas. I have tried using the postscript method of canvas to create a postscript file, but I get a blank page. I know this is because I have embedded widgets, and these do not get rendered by the postscript method. Before I rewrite my program to create a more printer-friendly layout, can someone suggest a way to approach this problem? All of the programming books I have ever read approach the problem of sending output to a printer with a bit of hand-waving, something along the lines of: "It's a difficult problem that depends on interacting with the operating system." I also have a hard time finding resources about this because of all the pages related to printing to the screen. I am using Python 2.6, on Ubuntu 9.04.

• Do you prefer to code on a Laptop or a Desktop, or both ?

  - by CAD bloke

  What is your primary development machine - a Desktop or a laptop? Why? Do you use both - if so, do you use source control to keep them synched? This might seem like a dumb question but I'm on the steep part of the learning curve & I'd be interested in your insights. [edit] - Using a laptop assumes hanging an Imax-sized screen off it when it is docked. Using a desktop assumes 2x Imax screens. [edit] - This is faster than Twitter! IDE is VS2008 - laptop is 17 (or 15) inch, 1920x1200

• How to redirect on apache after running a script through cgi

  - by Yotam

  I have an ubuntu machine which I have installed apache on. I want to use a web page to run some simple shell script through cgi and then go back to my home screen. I also want to the go-back step to be automatic. I have set a redirect in my apache.conf which works fine but the script doesn't run at all. Is there a way to run the script and only then apply the redirect? Comment: I think this may be the answer but I'm not sure.

• Multi "column" DataGridView C#

  - by Wesley

  I have a DataGridView that's bound to a DataSet. It has columns DateCreated, Weight, DateUsed. Those three columns do not take up much horizontal space on DataGridView that is nearly full screen. Is it possible to have those columns wrap back to the top if the view is wide enough to support a second group of those colums. So across the header it would read DateCreated, Weight, DateUsed, DateCreated, Weight, DateUsed. Then when a row is clicked, only 3 cells would be highlighted, not all six. Is there something that can provide this functionality?

• How to add padding for background image

  - by michael

  Hi, I have a linear layout which has a background image (a 9 patched png file). How can I add padding to left and right so that the background image does not take up the whole width? I have tried 'android:paddingLeft' and 'android:paddingRight', but that does not change anything. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:paddingLeft="25dip" android:paddingRight="25dip" android:background="@drawable/background"> The whole background still stretches the whole screen width. Thank you for any help.

• How do I get the name of the test method that was run in a testng tear down method?

  - by Zachary Spencer

  Basically I have a tear down method that I want to log to the console which test was just run. How would I go about getting that string? I can get the class name, but I want the actual method that was just executed. Class testSomething() { @AfterMethod public void tearDown() { system.out.println('The test that just ran was....' + getTestThatJustRanMethodName()'); } @Test public void testCase() { assertTrue(1==1); } } should output to the screen: "The test that just ran was.... testCase" However I don't know the magic that getTestThatJustRanMethodName should actually be.

• How to set Camera View as background with views over it?

  - by Android Student

  So, I'm trying to make the background to one of my apps look "futuristic." I thought of an idea to make the screen look almost transparent yet have views over it. So, it would look something like this: I'm thinking that I can use the camera to capture the background of the phone (without taking a picture, just having the real time view in the background) and then, if possible, place a semi-transparent slightly blurred ImageView over that. Finally, on top of that I can place the other views including the ImageButtons. So, my question is how would I go about doing this? I have searched but haven't found anything relevant. It must be possible; its just how to do it? I don't expect you to give me all the code as an answer, just if you have any ideas that can help or links or code that can point me in the right direction, it would be greatly appreciated! Thanks!

• IB z-order on simulator 6.0

  - by Stanley

  Consider the above's IB objects listing. Siblings further down the list should be on top of the siblings listed further up when rendered on the screen. Under Xcode 4.5.2, everything is ok if iphone simulator 5.1 is used. But for simulator 6.0 the map just covers everything. The same if using actual devices (phones) for testing. Hope that somebody knowledgeable could help. Please also add comments if you do not find such a problem on simulator 6.0. Because chances are the problem is related to how my project is setup. Update : Have setup a test project with the iOS 6 map view. There seems to be no problem with the z-order. So the problem should relate to my code.

• Is there a transformation matrix that can scale the x and/or y axis logarithmically?

  - by Dave M

  I'm using .net WPF geometry classes to graph waveforms. I've been using the matrix transformations to convert from the screen coordinate space to my coordinate space for the waveform. Everything works great and it's really simple to keep track of my window and scaling, etc. I can even use the inverse transform to calculate the mouse position in terms of the coordinate space. I use the built in Scaling and Translation classes and then a custom matrix to do the y-axis flipping (there's not a prefab matrix for flipping). I want to be able to graph these waveforms on a log scale as well (either x axis or y axis or both), but I'm not sure if this is even possible to do with a matrix transformation. Does anyone know if this is possible, and if it is, what is the matrix?

• What's wrong with the architecture of a game object drawing and updating itself?

  - by Ricket

  What are the reasons for and against a game object drawing and updating itself? For example, if you have a game where the player has a position on screen, why not have an all-encompassing class: public class Player { private int x, y, xVelocity, yVelocity; private Sprite s; //... public Player() { // load the sprite here, somehow? } public void draw(CustomGraphicsClass g) { g.draw(s, x, y); } public void update(long timeElapsed) { x += (xVelocity * timeElapsed); y += (yVelocity * timeElapsed); } } What is wrong with this design? What are the downfalls or concerns? How would you better write something like this, or better architect this type of thing in a game? Also, somewhat connected, how would you implement loading that Sprite image? And furthermore, how would you then implement collision between two Players? (I should probably separate these extra two questions into new questions, huh?)

• tmux: create session if none exists

  - by rampion

  I'm switching from using gnu-screen to tmux, and I'm still trying to wrap my head around changes. One thing I'd like to be able to do is start tmux and have it automatically connect to a session if one exists, and otherwise create a new session. tmux attach attaches to an automatically existing session - but errors out if no session exists tmux new creates a new session - but it does so every time, so I can't leave it in my .tmux.conf tmux has-session tests whether a session exists - but I don't know how to stitch it together with the other commands Can anyone give me some configure file advice?

• Load all tab bar views when application first runs

  - by codenoobie

  Here's the problem. I have a tab bar controller with 4 separate views. When I navigate from the first view to the second view, it takes some time to load up the second view. What I want to do is be able to load and initialize all of my tab bar views during my splash screen. That way, when the user navigates between the tab views, there is no wait time. So the question is... how do I manually initialize my individual tab bar views in my app delegate? And once again, thank you stackoverflow!

• Why doesn't Google OpenID provider work with PHP-OpenId on my server?

  - by Steven Devijver

  Hey, I'm using PHP-OpenId 2.1.3 which I've unzipped on my server here (this is the consumer example that comes with PHP-OpenId). When I enter the Google OpenId url (https://www.google.com/accounts/o8/id) and submit I get a blank screen. When I try the exact same example code on the PHP-OpenId website here with the same URL it works fine. I don't understand what I'm doing wrong. The only thing I can think of is that somehow Google does not want to work with my server. Any ideas how to make this work? Thanks

• Converting Informix 'Perform' screens to a Windows-based application

  - by Lunthita

  For the past several years we have slowly built an Access-based front end to access our InformixSE database (unix). Our Sun server will be shut down in a couple of months and I'm looking for a relatively inexpensive solution for porting over the remainder of our old ".per" screens to a Windows-based solution. And even for the screens that have been reprogrammed, there's nothing that beats being able to query any field on the screen like you could with those simple-to-get-up-and-running Informix "Perform" screens. Does anyone have experience with a solution?

• What is the best way to make a game timer in Actionscript 3?

  - by Nuthman

  I have built an online game system that depends on a timer that records how long it took a player to complete a challenge. It needs to be accurate to the millisecond. Their time is stored in a SQL database. The problem is that when I use the Timer class, some players are ending up getting scores in the database of less than a second. (which is impossible, as most challenges would take at least 11 seconds to complete even in a perfect situation.) What I have found is that if a player has too many browser windows open, and/or a slow computer, the flash game slows down actually affecting the timer speed itself. The timer is 'spinning' on screen so you can physically see the numbers slowing down. It is frustrating that I cannot just open a second thread or do something to allow flash to keep accurate time regardless of whatever else is going on in the program. Any ideas?
