  • Changing UI color in Eclipse

    - by Lo'oris
    I'm aware of this topic: I've used it to change most of the editor colors, and that's great. But that wasn't enought, there's still too much white (and I need to change it because it hurts my eyes). I've searched in the preferences (both using Eclipse itself and editing the files) for instances of while (255,255,255) and changed them all. Looks like I'm missing something. too much white in the UI: http://www.imagebanana.com/view/gy89qf7/eclipse_too_much_white_1.png totally white in this screen: http://www.imagebanana.com/view/j8282wf/eclipse_too_much_white_2.png

  • How do I calculate the average direction of two vectors

    - by Mike Broughton
    Hi, I am writing and opengl based iphone app and would like to allow a user to translate around a view based on the direction that they move two fingers on the screen. For one finger I know I could just calculate the vector from the start position to the current position of the users finger and then find the unit vector of this to get just the direction, but I don't know how I would do this for two fingers, I don't think adding the components of the vectors and calculating the average would work so I'm pretty much stuck... thanks in advance

  • Disable iOS keyboard (don't show it at all) in phonegap

    - by lashleigh
    If I were writing a native app I would try the solution given here which says: Try to implement the following method in text view's delegate: - (BOOL)textViewShouldBeginEditing:(UITextView *)textView{ return NO; } Unfortunately I need to use phonegap, so I don't have a text view to manipulate. It would be great if I could permanently suppress the keyboard in this app. We've got some custom on screen keyboard that people are supposed to use instead. So, any idea how to disable the popup keyboard completely?

  • How to create a generic Android XML layout for all activities

    - by zabawaba
    I have an application that needs the same items [5 buttons acting as tabs] in every screen. Is it possible to create a "base XML layout" that has these 5 buttons and then have all the other XML files extend from the bas layout in some way so that I don't have to have multiple buttons that will ultimately have the same functionality. Is there a better approach to this problem that can be supported by API 9

  • elisp: posn-at-point returns nil after goto-char. How to update the display before posn-at-point?

    - by Cheeso
    In emacs lisp, posn-at-point is documented as: posn-at-point is a built-in function in C source code. (posn-at-point &optional POS WINDOW) . Return position information for buffer POS in WINDOW. POS defaults to point in WINDOW; WINDOW defaults to the selected window. . Return nil if position is not visible in window. Otherwise, the return value is similar to that returned by event-start for a mouse click at the upper left corner of the glyph corresponding to the given buffer position: (WINDOW AREA-OR-POS (X . Y) TIMESTAMP OBJECT POS (COL . ROW) IMAGE (DX . DY) (WIDTH . HEIGHT)) The posn- functions access elements of such lists. ok, now I've got a function that looks something like this: (defun my-move-and-popup-menu () "move the point, then pop up a menu." (goto-char xxxx) (setq p (posn-at-point)) (my-popup-menu p ...) ) Basically, move the point, then retrieve the screen position at that point, and then popup a menu at that screen position. But I am finding that posn-at-point returns non-nil, only if the xxxx character position (the after position) is visible in the window, before the call to goto-char. It seems that the position is not actually updated until exit from the function. If goto-char goes a long way, more than one screenful, then the retrieved position is always nil, and my code doesn't know where to popup the menu. The reason I suggest that the position is not actually updated until exit from the function - when the menu successfully pops up, the cursor is clearly visible in its previous location while the popup menu is being displayed. When I dismiss the menu, the cursor moves to where I expected it to move, after the goto-char call. How can I get the position to be really updated, between goto-char and posn-at-point, so that posn-at-point will not return nil? In a Windows Forms application I would call Form.Update() or something similar to update the display in the middle of an event handler. What's the emacs version of that?

  • Android menu view, gridview or something else?

    - by dfilkovi
    I need to create a home screen (menu) with four to six items arranged in a grid view, each item needs to have an icon and a text below the icon. I googled and everything I could find were adapterView examples, with dynamic menu loading, and I want to make it with static xml, this view will not change so no need for dynamic code. Can anyone post an xml example of this?

  • mvc partial views loses track of the images folder when using jquery

    This is what I have and it works: $(function(){ $('.slide-out-div').tabSlideOut({ tabHandle: '.handle', //class of the element that will become your tab pathToTabImage: 'http://mhmiisdev2/images/contact_tab.gif', //path to the image for the tab //Optionally can be set using css imageHeight: '122px', //height of tab image //Optionally can be set using css imageWidth: '40px', //width of tab image //Optionally can be set using css tabLocation: 'right', //side of screen where tab lives, top, right, bottom, or left speed: 300, //speed of animation action: 'click', //options: 'click' or 'hover', action to trigger animation topPos: '200px', //position from the top/ use if tabLocation is left or right leftPos: '20px', //position from left/ use if tabLocation is bottom or top fixedPosition: true //options: true makes it stick(fixed position) on scroll }); }); This is what I want and it doesnt work when I change from one controller to another controller.

  • Is it even possible to change a UIButtons background color??

    - by dubbeat
    Hey, This one has me stumped. Is it possible at all to change the background color of a UIButton in Cocoa for iphone. I've tried setting the background color but it only changes the corners. SetBackgroundColor seems to be the only method available for such things. Please refer to my screen shot [random setBackgroundColor:[UIColor blueColor]]; [random.titleLabel setBackgroundColor:[UIColor blueColor]];

  • Calling compiled C from R with .C()

    - by Sarah
    I'm trying to call a program (function getNBDensities in the C executable measurementDensities_out) from R. The function is passed several arrays and the variable double runsum. Right now, the getNBDensities function basically does nothing: it prints to screen the values of passed parameters. My problem is the syntax of calling the function: array(.C("getNBDensities", hr = as.double(hosp.rate), # a vector (s x 1) sp = as.double(samplingProbabilities), # another vector (s x 1) odh = as.double(odh), # another vector (s x 1) simCases = as.integer(x[c("xC1","xC2","xC3")]), # another vector (s x 1) obsCases = as.integer(y[c("yC1","yC2","yC3")]), # another vector (s x 1) runsum = as.double(runsum), # double DUP = TRUE, NAOK = TRUE, PACKAGE = "measurementDensities_out")$f, dim = length(y[c("yC1","yC2","yC3")]), dimnames = c("yC1","yC2","yC3")) The error I get, after proper execution of the function (i.e., the right output is printed to screen), is Error in dim(data) <- dim : attempt to set an attribute on NULL I'm unclear what the dimensions are that I should be passing the function: should it be s x 5 + 1 (five vectors of length s and one double)? I've tried all sorts of combinations (including sx5+1) and have found only seemingly conflicting descriptions/examples online of what's supposed to happen here. For those who are interested, the C code is below: #include <R.h> #include <Rmath.h> #include <math.h> #include <Rdefines.h> #include <R_ext/PrtUtil.h> #define NUM_STRAINS 3 #define DEBUG void getNBDensities( double *hr, double *sp, double *odh, int *simCases, int *obsCases, double *runsum ); void getNBDensities( double *hr, double *sp, double *odh, int *simCases, int *obsCases, double *runsum ) { #ifdef DEBUG for ( int s = 0; s < NUM_STRAINS; s++ ) { Rprintf("\nFor strain %d",s); Rprintf("\n\tHospitalization rate = %lg", hr[s]); Rprintf("\n\tSimulation probability = %lg",sp[s]); Rprintf("\n\tSimulated cases = %d",simCases[s]); Rprintf("\n\tObserved cases = %d",obsCases[s]); Rprintf("\n\tOverdispersion parameter = %lg",odh[s]); } Rprintf("\nRunning sum = %lg",runsum[0]); #endif } naive solution While better (i.e., potentially faster or syntactically clearer) solutions may exist (see Dirk's answer below), the following simplification of the code works: out<-.C("getNBDensities", hr = as.double(hosp.rate), sp = as.double(samplingProbabilities), odh = as.double(odh), simCases = as.integer(x[c("xC1","xC2","xC3")]), obsCases = as.integer(y[c("yC1","yC2","yC3")]), runsum = as.double(runsum)) The variables can be accessed in >out.

  • ob_start() -> ob_flush() doesn't work

    - by MB34
    I am using ob_start()/ob_flush() to, hopefully, give me some progress during a long import operation. Here is a simple outline of what I'm doing: <?php ob_start (); echo "Connecting to download Inventory file.<br>"; $conn = ftp_connect($ftp_site) or die("Could not connect"); echo "Logging into site download Inventory file.<br>"; ftp_login($conn,$ftp_username,$ftp_password) or die("Bad login credentials for ". $ftp_site); echo "Changing directory on download Inventory file.<br>"; ftp_chdir($conn,"INV") or die("could not change directory to INV"); // connection, local, remote, type, resume $localname = "INV"."_".date("m")."_".date('d').".csv"; echo "Downloading Inventory file to:".$localname."<br>"; ob_flush(); flush(); sleep(5); if (ftp_get($conn,$localname,"INV.csv",FTP_ASCII)) { echo "New Inventory File Downloaded<br>"; $datapath = $localname; ftp_close($conn); } else { ftp_close($conn); die("There was a problem downloading the Inventory file."); } ob_flush(); flush(); sleep(5); $csvfile = fopen($datapath, "r"); // open csv file $x = 1; // skip the header line $line = fgetcsv($csvfile); $y = (feof($csvfile) ? 2 : 5); while ((!$debug) ? (!feof($csvfile)) : $x <= $y) { $x++; $line = fgetcsv($csvfile); // do a lot of import stuff here with $line ob_flush(); flush(); sleep(1); } fclose($csvfile); // important: close the file ob_end_clean(); However, nothing is being output to the screen at all. I know the data file is getting downloaded because I watch the directory where it is being placed. I also know that the import is happening, meaning that it is in the while loop, because I can monitor the DB and records are being inserted. Any ideas as to why I am not getting output to the screen?

  • What's the best CDN for image hosting on a high-volume web site?

    - by Mike
    Akamai is way too expensive. Photobucket is not reliable. Is there a great content delivery network that I can use just to host my images? We deploy images programmatically via FTP, so there is some programming behind the scenes. Having some sort of reporting about the reliability of the service, whether it's raw logs files or a web-based admin screen that shows http errors, would also be important. Has anyone worked with edgecast?

  • How to change color of selected references

    - by user272924
    Visual Studio 2010 highlights all references to the same variable (or class) when your cursor is placed over it. with the theme I use highlighted references are white on white - making them virtually impossible to read. what is the name of "display item" in Options- Environment Fonts and Colors that is responsible for that color? changing Plain Text to a darker one partially solves an issue however that also changes color for lots of other stuff on a screen, so ideally would be to change a background for this type of "selection"..

  • iPhone - Track three touches

    - by Striker
    Suppose you have three points of contact on the iPhone screen and one of those touches moves... The touchesMoved method will be invoked and the [[event touchesForView:self] count] will be equal to '3' because there are three touches for the event, but how can you distinguish between the touches? For example - find out whether it was the first, second, or third touch which moved? Thanks.
