  • GWT celltable Simple pager Next and previous buttons

    - by Saritha
    I am working on a CellTable with a SimplePager. My paging works fine in the sense when i set the page size to be 5 only 5 records are being displayed. My question is that do next and previous buttons come by default or do we have to configure them. I have seen the show case example code and i do not see any external configurations . my SimplePager code is as follows: //create pager SimplePager.Resources resources = GWT.create(SimplePager.Resources.class); SimplePager simplePager = new SimplePager(TextLocation.CENTER, resources , false, 0, true); simplePager.setDisplay(cellTableSearchResults); simplePager.setPageSize(5); // create data provider ListDataProvider<GridDTO> dataProvider = new ListDataProvider<GridDTO>(); dataProvider.addDataDisplay(cellTableSearchResults); dataProvider.setList(components); Please help.

  • Best keyboards for emacs?

    - by catphive
    For emacs users out there, what are your recommended keyboards? Bonus points for keyboards that: Have no capslock key. Instead, a control key in that position. Alt keys that are closer to the center, and easier to use with meta key combos. I find alt keys too far to the left to be a bit awkward to hit with my thumb in some key combos. Help ergonomically with emacs in other ways. I'm not a huge fan of model M style high and clacky keys. I instead prefer laptop style flat keys; however, I'm not disqualifying either category.

  • Move document.ready function to a separate javascript fucntion?

    - by tonsils
    Hi, Is it possible to move the following code within a jQuery document.ready function into a separate javascript function, so that it can be called just like any other javascript function, i.e.: <script type="text/javascript"> $(document).ready(function() { $('div#infoi img[title]').qtip({ position: { adjust: { x:-110, y:0 }, corner: { target: 'bottomLeft', tooltip: 'topMiddle' } }, style: { width: 250, padding: 5, background: '#E7F1FA', color: 'black', textAlign: 'center', border: { width: 3, color: '#65a9d7' }, tip: 'topRight' } }); }); </script> If yes, then how - if not, then that answers my question. Thanks.

  • Scala, represent pattern of boolean tuple into something else.

    - by Berlin Brown
    This is a cellular automata rule (input Boolean == Left, Center, Right Cell) and output Boolean . What is a better way to represent this in Scala. trait Rule { def ruleId() : Int def rule(inputState:(Boolean, Boolean, Boolean)) : Boolean override def toString : String = "Rule:" + ruleId } class Rule90 extends Rule { def ruleId() = 90 def rule(inputState:(Boolean, Boolean, Boolean)) : Boolean = { // Verbose version, show all 8 states inputState match { case (true, true, true) => false case (true, false, true) => false case (false, true, false) => false case (false, false, false) => false case _ => true } } }

  • Positioning the dialog box in the centre of the screen

    - by ame
    I have a dialog box developed in mfc for a Windows CE device and want it to occupy the entire screen. I used the following code to center my dialog box on the lcd screen of the device: CWnd* pWnd = GetDesktopWindow(); CenterWindow(pWnd); However, I still get a tiny sliver of space on the left side of the dialog box, resizing the dialog merely makes it overflow on the right side of the LCD while the tiny space on the left remains (I can see the blue of the win CE desktop behind.) Are there any suggestions to solve this problem? I checked the margin settings for this dialog box in my .rc files and leftmargin and topmargin are both set to 0. I was wondering if I could get the coordinates of the centre of the screen and then place my window one or two points to the left to deal with the current offset. A messy approach I know!

  • What would be my best MySQL Synchronization method?

    - by Kerry
    We're moving a social media service to be on separate data centers with global load balancing, as our other hosting provider's entire data center went down. Twice. This means that both websites need to be synchronized in some sense -- I'm less worried about the code of the pages, that's easy enough to sync, but they need to have the same database data. From my research on SO, it seems MySQL Replication is a good option, but the MySQL manual, for scaling out, says that its best when there are far more reads then there are writes/updates: http://dev.mysql.com/doc/refman/5.0/en/replication-solutions-scaleout.html In our case, it's about equal. We're getting around 200-300 thousand requests a day right now, and we can grow rapidly. Every request is both a read and write request. What would be the best method or tool to handle this?

  • NotificationCenter Widget Failed To Use CoreLocation

    - by James Ye
    I'm writing a notification center widget, and it had to use location information. In normal apps I use CoreLocation and it works fine. But in my widget, I tried to locationServicesEnabled but it didn't go to the callback functions, and the authorizationStatus is always kCLAuthorizationStatusNotDetermined, and the authorize setting didn't show up in Setting - location service. I already set the delegate to the class. The system's Yahoo weather widget can auto locating and it uses CoreLocation too, so the widget do have ability to use location service. Why CoreLocation doesn't work on my widget?

  • Detecting crosses in an image

    - by MrOrdinaire
    I am working on a program to detect the tips of a probing device and analyze the color change during probing. The input/output mechanisms are more or less in place. What I need now is the actual meat of the thing: detecting the tips. In the images below, the tips are at the center of the crosses. I thought of applying BFS to the images after some threshold'ing but was then stuck and didn't know how to proceed. I then turned to OpenCV after reading that it offers feature detection in images. However, I am overwhelmed by the vast amount of concepts and techniques utilized here and again, clueless about how to proceed. Am I looking at it the right way? Can you give me some pointers? Image extracted from short video Binary version with threshold set at 95

  • Determining where to animate the map given a list of GeoPoints

    - by Itsik
    My android application loads some markers on an overlay onto a MapView. The markers are placed based on a dynamic list of GeoPoints. I want to move the map center and zoom into the area with most items. Naively, I can calculate the superposition of all the points, but I would like to remove the points that are very far from the mass of points from the calculation. Is there a known way to calculate this ? (e.g. probability, statistics .. ?)

  • How to draw to screen in c++ ?

    - by Kesarion
    How would I draw something on the screen ? not the console window but the entire screen, preferably with the console minimised. Also, would it show up on a printscreen ? What I want to do is create something like a layer on top of the screen that only me and my aplication are aware of yet still be able to use aplications as usual. Here's an example: Let's say I want 2 yellow squares 5 by 5 pixels in size appearing in the center of the screen on top of all the other applications, unclickable and invisible to a printscreen.

  • How to make a custom installer for games, etc?

    - by Dodi300
    Hello. Can anyone tell me how to create a custom installer to 'install' games. I say custom meaning I don't want the user to have the option where the game is installed. I want it to be a straight forward process, maybe with just one loading bar. The program I'm developing is a 'center' for game playing, which includes a community and other features, such as a timer that records how long a game is played for. I just thought that installing each game in one place, with a simple installer would make the program easier to use. It also will allow me to do other features as the games will all be installed in one place. No need for the user to specify where the game is installed. Would this be possible?

  • Math - Convert Arbitrary Length to Range From -1.0 to 1.0?

    - by TheDarkIn1978
    how can i convert a length into a range of -1.0 to 1.0? example: my stage is 440px in length and accepts mouse events. i would like to click in the middle of the stage, and rather than an output of X = 220, i'd like it to be X = 0. similarly, i'd like the real X = 0 to become X = -1.0 and the real X = 440 to become X = 1.0. i don't have access to the stage, so i can't simply center-register it, which would make this process a lot easier. also, it's not possible to dynamically change the actual size of my stage, so i'm looking for a formula that will translate the mouse's real X coordinate of the stage to evenly fit within a range from -1 to 1.

  • Drawing a 2D line on a canvas

    - by Jason94
    I have the datalist = 62, 76, 80, 72, 71, 75, 77 that i want to present as a 2D line drawed point to point. In my Wpf application i have a canvas with the height: 173 and width: 455. How do i go about it and draw a line by my datalist and use almost the whole height of the canvas? as it is now the data is just represented on a line at the bottom at the canvas, not using (and therefor giving a bad representation of the data) whole heigh of the canvas. It would also be nice to place it in the center of the box too...

  • What if Web page's background matters

    - by hgulyan
    Hi, I have a complex background image and images, that should be on exact positions of the background image. How can I organize web page? I can't use absolute positions, because I need to organize background to view it nice on any monitor, any resolution and any browser. It can be aligned to center or smth else. Web page can be written just with HTML, Javascript or with a library like JQuery. Here's an example of what kind of web page I'd like to have. http://desandro.com/portfolio/ (background picture and points on it) Thanks in advance.

  • How do I update mysql database when posting form without using hidden inputs?

    - by user1322707
    I have a "members" table in mysql which has approximately 200 field names. Each user is given up to 7 website templates with 26 different values they can insert unique data into for each template. Each time they create a template, they post the form with the 26 associated values. These 26 field names are the same for each template, but are differentiated by an integer at the end, ie _1, _2, ... _7. In the form submitting the template, I have a variable called $pid_sum which is inserted at the end of each field name to identify which template they are creating. For instance: <form method='post' action='create.template.php'> <input type='hidden' name='address_1' value='address_1'> <input type='hidden' name='city_1' value='city_1'> <input type='hidden' name='state_1' value='state_1'> etc... <input type='hidden' name='address_1' value='address_2'> <input type='hidden' name='city_1' value='city_2'> <input type='hidden' name='state_1' value='state_2'> etc... <input type='hidden' name='address_2' value='address_3'> <input type='hidden' name='city_2' value='city_3'> <input type='hidden' name='state_2' value='state_3'> etc... <input type='hidden' name='address_2' value='address_4'> <input type='hidden' name='city_2' value='city_4'> <input type='hidden' name='state_2' value='state_4'> etc... <input type='hidden' name='address_2' value='address_5'> <input type='hidden' name='city_2' value='city_5'> <input type='hidden' name='state_2' value='state_5'> etc... <input type='hidden' name='address_2' value='address_6'> <input type='hidden' name='city_2' value='city_6'> <input type='hidden' name='state_2' value='state_6'> etc... <input type='hidden' name='address_2' value='address_7'> <input type='hidden' name='city_2' value='city_7'> <input type='hidden' name='state_2' value='state_7'> etc... // Visible form user fills out in creating their template ($pid_sum converts // into an integer 1-7, depending on what template they are filling out) <input type='' name='address_$pid_sum'> <input type='' name='city_$pid_sum'> <input type='' name='state_$pid_sum'> etc... <input type='submit' name='save_button' id='save_button' value='Save Settings'> <form> Each of these need updated in a hidden input tag with each form post, or the values in the database table (which aren't submitted with the form) get deleted. So I am forced to insert approximately 175 hidden input tags with every creation of 26 new values for one of the 7 templates. Is there a PHP function or command that would enable me to update all these values without inserting 175 hidden input tags within each form post? Here is the create.template.php file which the form action calls: <?php $q=new Cdb; $t->set_file("content", "create_template.html"); $q2=new CDB; $query="SELECT menu_category FROM menus WHERE link='create.template.ag.php'"; $q2->query($query); $toall=0; if ($q2->nf()<1) { $toall=1; } while ($q2->next_record()) { if ($q2->f('menu_category')=="main") { $toall=1; } } if ($toall==0) { get_logged_info(); $q2=new CDB; $query="SELECT id FROM menus WHERE link='create_template.php'"; $q2->query($query); $q2->next_record(); $query="SELECT membership_id FROM menu_permissions WHERE menu_item='".$q2->f("id")."'"; $q2->query($query); while ($q2->next_record()) { $permissions[]=$q2->f("membership_id"); } if (count($permissions)>0) { $error='<center><font color="red"><b>You do not have access to this area!<br><br>Upgrade your membership level!</b></font></center>'; foreach ($permissions as $value) { if ($value==$q->f("membership_id")) { $error=''; break; } } if ($error!="") { die("$error"); } } } $member_id=$q->f("id"); $pid=$q->f("pid"); $pid_sum = $pid +1; $first_name=$q->f("first_name"); $last_name=$q->f("last_name"); $email=$q->f("email"); echo " // THIS IS WHERE THE HTML FORM GOES "; replace_tags_t($q->f("id"), $t); ?>

  • update dialog title for each click

    - by Scarface
    Hey guys I have a quick question, I have a dialog box that has multiple links with different attributes. Each time a link is clicked, the attribute src is printed inside of the dialog box so that each link has a unique output in the dialog. My problem is simply that only the first src title is in every box and I would like to change that as well with each click. I separated the line containing title to show the problem. If anyone has any ideas I would appreciate it. <a class="open" src="something" title="Click to play">link</a> <a class="open" src="something else" title="Click to play">link2</a> $('.open').click(function() { src=$(this).attr('src'); $('#show').html(''+src+''); $(\"#show\").dialog({hide: 'clip', width: 400,height: 150,position: 'center', show: 'clip',stack: true,title: ''+src+'', minHeight: 25, minWidth: 100, autoOpen: false,resizable:false}); $('#show').dialog('open'); })

I'm not sure If i'm being clear. I've searched but all I found is the css position fixed stuff. Can you help me with a link or something? Best Regards

  • CALayer Position Contents to Bottom Left

    - by Louis
    I am attempting to draw an image onto a CALayer. I only need an image, so I have created my later as follows: CALayer *layer = [CALayer layer]; I add my image as follows: NSImage *img = [[NSImage alloc] initWithContentsOfFile:@"path/to/img.png"]; [layer setContents:img]; This works, however it draws my images to fill the entire parent frame (stretching my image in the process). Reading the docs, I found the following: [layer setContentsGravity:@"kCAGravityBottomLeft"]; I am attempting to draw my image in the bottom left of the parent frame, however no matter what I do it draws my icon in the bottom center. Is there anyway to specify the bottom left?
