  • CSS- removing horizontal space in list menu using display inline property

    - by Kayote
    Hi All, Im new to CSS and have a set target of learning & publishing my website in CSS by the end of the month. My question: Im trying to build a CSS horizontal menu with hover drop downs, however, when I use the 'display: inline' property with li (list) items, I get horizontal spaces between the li (list) items in the bar. How do I remove this space? Here is the html: <div id="tabas_menu"> <ul> <li id="tabBut0" class="tabBut">Overview</li> <li id="tabBut1" class="tabBut">Collar</li> <li id="tabBut2" class="tabBut">Sleeves</li> <li id="tabBut3" class="tabBut">Body</li> </ul> </div> And here is the CSS: #tabas_menu { position: absolute; background: rgb(123,345,567); top: 110px; left: 200px; } ul#tabas_menu { padding: 0; margin: 0; } .tabBut { display: inline; white-space: list-style: none; background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(rgba(255,142,190,1)),to(rgba(188,22,93,1))); background: -moz-linear-gradient(top, rgba(255,142,190,1), rgba(188,22,93,1)); font-family: helvetica, calibri, sans-serif; font-size: 16px; font-weight: bold; line-height: 20px; text-shadow: 1px 1px 1px rgba(99,99,99,0.5); -moz-border-radius: 0.3em; -moz-box-shadow: 0px 0px 2px rgba(0,0,0,0.5); -webkit-border-radius: 0.3em; -webkit-box-shadow: 0px 0px 2px rgba(0,0,0,0.5); padding: 6px 18px; border: 1px solid rgba(0,0,0,0.4); margin: 0; } I can get the space removed using the 'float: left/right' property but its bugging me as to why I cannot achieve the same effect by just using the display property.

  • recommending gcc to inline the function

    - by thetna
    I don't know how feasible it is and how sensible is this question here. Is there any changes that we can make in makefile to recommend GCC inline all the function although the functions are not inlined during the declaration or nowhere in the source file.

  • Better solution then simple factory method when concrete implementations have different attributes

    - by danip
    abstract class Animal { function eat() {..} function sleep() {..} function isSmart() } class Dog extends Animal { public $blnCanBark; function isSmart() { return $this->blnCanBark; } } class Cat extends Animal { public $blnCanJumpHigh; function isSmart() { return $this->blnCanJumpHigh; } } .. and so on up to 10-20 animals. Now I created a factory using simple factory method and try to create instances like this: class AnimalFactory { public static function create($strName) { switch($strName) { case 'Dog': return new Dog(); case 'Cat': return new Cat(); default: break; } } } The problem is I can't set the specific attributes like blnCanBark, blnCanJumpHigh in an efficient way. I can send all of them as extra params to create but this will not scale to more then a few classes. Also I can't break the inheritance because a lot of the basic functionality is the same. Is there a better pattern to solve this?

  • Evaluating php generated javascript "inline"?

    - by talkingnews
    If you look at the source of this page http://kingston.talking-newspapers.co.uk/ you will see a large amount of inline javascript near the top. I don't really want all this extra stuff floating around in my page source, I'd much rather get it off into a script tag, and then I can minify it and all sorts. If I call it as a php file, this SHOULD work in theory, I just end the js file extension with php instead, and in the header I put the following: header("Content-type:application/x-javascript"); but... a lot of the php variables used to generate the playlist within the javascript are setup at the beginning of the main index.php file, and in calling this php-generated js playlist file like this, it seems to evaluate it entirely separately, so it's full of errors. The only way round it I can think of is to have the page write a file, then immediately read it in. The other thing is, the playlist is likely to change often and dynamically, so I think I need to get minify to NOT cache it?

  • C2244 when trying to call the pow function from inline assembly

    - by schrödingers cat
    I would like to call the pow function from inline assembly. The problem is i'm getting error C2244: 'pow' : unable to match function definition to an existing declaration. I'm new to assembly so this may be a trivial question but how do i resolve this? I guess it has something to do with the compiler not beeing able to properly resolve the overload of pow. The following code fragment is causing the error: do_POW: // push first argument to the stack sub esp, size value_type fld qword ptr [ecx] fstp qword ptr [esp] // push second argument to the stack sub esp, size value_type fld qword ptr [ecx - size value_type] fstp qword ptr [esp]and pop fpu stack // call the pow function call pow sub ecx, size value_type fstp qword ptr [ecx] add esp, 2 * size value_type jmp loop_start

  • Pros and Cons of Different macro function / inline methods in C

    - by Robert S. Barnes
    According to the C FAQ, there are basically 3 practical methods for "inlining" code in C: #define MACRO(arg1, arg2) do { \ /* declarations */ \ stmt1; \ stmt2; \ /* ... */ \ } while(0) /* (no trailing ; ) */ or #define FUNC(arg1, arg2) (expr1, expr2, expr3) To clarify this one, the arguments are used in the expressions, and the comma operator returns the value of the last expression. or using the inline declaration which is supported as an extension to gcc and in the c99 standard. The do { ... } while (0) method is widely used in the Linux kernel, but I haven't encountered the other two methods very often if at all. I'm referring specifically to multi-statement "functions", not single statement ones like MAX or MIN. What are the pros and cons of each method, and why would you choose one over the other in various situations?

  • Inline javascript performance.

    - by Geromey
    I know it is better coding practice to avoid inline javascript like: <img id="the_image" onclick="do_this(true);return false;"/> I am thinking about switching this kind of stuff for bound jquery click events like: $("#the_image").bind("click",function(){ do_this(true); return false; }); Will I lose any performance if I bind a ton of click events? I am not worried about the time it takes to initially bind the events, but the response times between clicking and it happening. I bet if there is a difference, it is negligible, but I will have a ton of functions bound. I'm wondering if browsers treat the onclick attribute the same way as a bound event. Thanks

  • C inline assembly of x96 fbstp instruction

    - by David HUnter
    Was wondering how to inline a usage of fbstp on a 32 bit I86 architecture. I tried something like int main( ) { double foo = 100.0; long bar = 0; asm( "pushl %1; fbstp %0" : "=m"(bar) : "r"(foo) ); ... But bar is unchanged. I have tried reading everything I can find on this but most example simply do things like add two integers together. I can’t find any that talk about pushing operands onto the stack and what I should be doing when an instruction like fbstp writes 80 bits of data back to memory ( i.e. what C type to use ) and how to specify it in the asm syntax. Also on x86-64 there seems to be a pushq and no pushl but fbstp still exists whereas fbstq does not. Is there some other magic for 64 bit.

  • How to inline string.h function on linux?

    - by tz1
    I want to optimize some code such that all the functions in string.h will be inlined. I'm on x86_64. I've tried -O3, -minline-all-stringops and when I do "nm a.out" it shows it is calling the glibc version. Checking with gcc -S, I see the calls. What am I missing? There are dozens of #ifdef _SOME_SETTING_ in string.h, and bits/string3.h shows the inline version, but I don't know how to get there. for example: $ cat test.c include main() { char *a, b; strcpy(b,a); } / When compiled with: gcc -minline-all-stringops -O6 -I. -S -o test.S test.c .file "test.c" .text .p2align 4,,15 .globl main .type main, @function main: .LFB12: .cfi_startproc subq $8, %rsp .cfi_def_cfa_offset 16 xorl %esi, %esi xorl %edi, %edi call strcpy addq $8, %rsp .cfi_def_cfa_offset 8 ret .cfi_endproc .LFE12: .size main, .-main .ident "GCC: (GNU) 4.5.1 20100924 (Red Hat 4.5.1-4)" .section .note.GNU-stack,"",@progbits */

  • Fancybox2 Inline Content Gallery

    - by beefchimi
    I am trying to create a gallery of inline content with Fancybox 2, and am failing miserably. I checked out some other resources online and they seem to indicate doing this relatively easily, yet, I cannot seem to get it to work. Here is my fiddle: http://jsfiddle.net/beefchimi/jtxHd/2/ Now, I feel like the fiddle is not loading the resources, so thats a problem. But even with the resources this does not work, I get the fancybox error. Resources: http://fancyapps.com/fancybox/source/jquery.fancybox.pack.js?v=2.1.3 http://fancyapps.com/fancybox/source/jquery.fancybox.css?v=2.1.3 Any help would be greatly appreciated. EDIT: So I can't submit my question without including some code, because linking to jsfiddle isn't okay, so, here is my fancybox initialization, which you will also find in the jsfiddle: $(document).ready(function() { $('a.inlinepopup').fancybox({ 'width' : '75%', 'height' : '75%', 'autoScale' : false, 'type' : 'iframe' }); });

  • Django Admin: OneToOne Relation as an Inline?

    - by Jim Robert
    I am putting together the admin for a satchmo application. Satchmo uses OneToOne relations to extend the base Product model, and I'd like to edit it all on one page. It is possible to have a OneToOne relation as an Inline? If not, what is the best way to add a few fields to a given page of my admin that will eventually be saved into the OneToOne relation? for example: class Product(models.Model): name = models.CharField(max_length=100) ... class MyProduct(models.Model): product = models.OneToOne(Product) ... I tried this for my admin but it does not work, and seems to expect a Foreign Key: class ProductInline(admin.StackedInline): model = Product fields = ('name',) class MyProductAdmin(admin.ModelAdmin): inlines = (AlbumProductInline,) admin.site.register(MyProduct, MyProductAdmin) Which throws this error: <class 'satchmo.product.models.Product'> has no ForeignKey to <class 'my_app.models.MyProduct'> Is the only way to do this a Custom Form? edit: Just tried the following code to add the fields directly... also does not work: class AlbumAdmin(admin.ModelAdmin): fields = ('product__name',)

  • Inline image and caption in article - conform caption's width to image's width

    - by Micah
    Here's my code: <div class="image"> <img src="image.jpg" alt="Image description" /> <p class="caption">This is the image caption</p> </div> Here's my CSS: .image { position: relative; float: right; margin: 8px 0 10px 10px; } .caption { font-weight: bold; color: #444666; } As is above, the caption will conform to the width of div.image. My problem is often the img varies in size, from 100px width to 250px width. I'd like to make the caption width conform to the corresponding width of the image, no matter the size. While I'd love for this to be more semantic as well, I'm not sure how easy it would be to switch p.caption with img. Of course, I'd prefer that method but am taking this a step at a time. Is there some jquery code that I can use to detect the width of the image and add that width as an inline style to the caption tag? Is there a better way to do this? I'm open to suggestions.

  • Adding a button or link to an inline in Django admin

    - by Lexo
    Hello, I have created the following django models: class Entry(SiteObject): parent = models.ForeignKey(Blog, related_name="entries") content = models.TextField(help_text = "The Content of the blog post") class EntryImage(models.Model): entry = models.ForeignKey(Entry, related_name="entryimages") imagewidth = models.PositiveIntegerField(editable=False,) imageheight = models.PositiveIntegerField(editable=False,) image_file = ImageWithThumbnailsField( #from sorl-thumbnail. Basically a wrapper for an ImageField that generates a thumbnail. upload_to="images/blogs", height_field="imageheight", width_field="imagewidth", help_text = "Select an image to upload.", thumbnail={'size': (360,720)}, generate_on_save=True, ) The EntryImage class shows up as an inline in the admin page for Entry. What I'd like to do is place a link or a button beside each of these inlines that does the following: Save the EntryImage Append <Image x> to the content of the Entry, where x is the number of the EntryImage. This will be replaced by the image's thumbnail using a template filter. Save the Entry Return to editing the Entry I have looked into this, but I just can't wrap my head around where I'm supposed to add this button or link. Has anyone else tried something similar? I've got JQuery available, since I'm using WYMEditor for the content field of the Entry class. Would this help? Thanks in advance, Lexo

  • Responsive Inline Elements with Twitter Bootstrap

    - by MightyZot
    Originally posted on: http://geekswithblogs.net/MightyZot/archive/2013/11/12/responsive-inline-elements-with-twitter-bootstrap.aspxTwitter Boostrap is a responsive css platform created by some dudes affiliated with Twitter and since supported and maintained by an open source following. I absolutely love the new version of this css toolkit. They rebuilt it with a mobile first strategy and it’s very easy to layout pages once you get the hang of it. Using a css / javascript framework like bootstrap is certainly much easier than coding your layout by hand. And, you get a “leg up” when it comes to adding responsive features to your site. Bootstrap includes column layout classes that let you specify size and placement based upon the viewport width. In addition, there are a handful of responsive helpers to hide and show content based upon the user’s device size. Most notably, the visible-xs, visible-sm, visible-md, and visible-lg classes let you show content for devices corresponding to those sizes (they are listed in the bootstrap docs.) hidden-xs, hidden-sm, hidden-md, and hidden-lg let you hide content for devices with those respective sizes. These helpers work great for showing and hiding block elements. Unfortunately, there isn’t a provision yet in Twitter Bootstrap (as of the time of this writing) for inline elements. We are using the navbar classes to create a navigation bar at the top of our website, www.crowdit.com. When you shrink the width of the screen to tablet or phone size, the tools in the navbar are turned into a drop down menu, and a button appears on the right side of the navbar. This is great! But, we wanted different content to display based upon whether the items were on the navbar versus when they were in the dropdown menu. The visible-?? and hidden-?? classes make this easy for images and block elements. In our case, we wanted our anchors to show different text depending upon whether they’re in the navbar, or in the dropdown. span is inherently inline and it can be a block element. My first approach was to create two anchors for each options, one set visible when the navbar is on a desktop or laptop with a wide display and another set visible when the elements converted to a dropdown menu. That works fine with the visible-?? and hidden-?? classes, but it just doesn’t seem that clean to me. I put up with that for about a week…last night I created the following classes to augment the block-based classes provided by bootstrap. .cdt-hidden-xs, .cdt-hidden-sm, .cdt-hidden-md, .cdt-hidden-lg {     display: inline !important; } @media (max-width:767px) {     .cdt-hidden-xs, .cdt-hidden-sm.cdt-hidden-xs, .cdt-hidden-md.cdt-hidden-xs, .cdt-hidden-lg.cdt-hidden-xs {         display: none !important;     } } @media (min-width:768px) and (max-width:991px) {     .cdt-hidden-xs.cdt-hidden-sm, .cdt-hidden-sm, .cdt-hidden-md.cdt-hidden-sm, .cdt-hidden-lg.cdt-hidden-sm {         display: none !important;     } } @media (min-width:992px) and (max-width:1199px) {     .cdt-hidden-xs.cdt-hidden-md, .cdt-hidden-sm.cdt-hidden-md, .cdt-hidden-md, .cdt-hidden-lg.cdt-hidden-md {         display: none !important;     } } @media (min-width:1200px) {     .cdt-hidden-xs.cdt-hidden-lg, .cdt-hidden-sm.cdt-hidden-lg, .cdt-hidden-md.cdt-hidden-lg, .cdt-hidden-lg {         display: none !important;     } } .cdt-visible-xs, .cdt-visible-sm, .cdt-visible-md, .cdt-visible-lg {     display: none !important; } @media (max-width:767px) {     .cdt-visible-xs, .cdt-visible-sm.cdt-visible-xs, .cdt-visible-md.cdt-visible-xs, .cdt-visible-lg.cdt-visible-xs {         display: inline !important;     } } @media (min-width:768px) and (max-width:991px) {     .cdt-visible-xs.cdt-visible-sm, .cdt-visible-sm, .cdt-visible-md.cdt-visible-sm, .cdt-visible-lg.cdt-visible-sm {         display: inline !important;     } } @media (min-width:992px) and (max-width:1199px) {     .cdt-visible-xs.cdt-visible-md, .cdt-visible-sm.cdt-visible-md, .cdt-visible-md, .cdt-visible-lg.cdt-visible-md {         display: inline !important;     } } @media (min-width:1200px) {     .cdt-visible-xs.cdt-visible-lg, .cdt-visible-sm.cdt-visible-lg, .cdt-visible-md.cdt-visible-lg, .cdt-visible-lg {         display: inline !important;     } } I created these by looking at the example provided by bootstrap and consolidating the styles. “cdt” is just a prefix that I’m using to distinguish these classes from the block-based classes in bootstrap. You are welcome to change the prefix to whatever feels right for you. These classes can be applied to spans in textual content to hide and show text based upon the browser width. Applying the styles is simple… <span class=”cdt-visible-xs”>This text is visible in extra small</span> <span class=”cdt-visible-sm”>This text is visible in small</span> Why would you want to do this? Here are a couple of examples, shown in screen shots. This is the CrowdIt navbar on larger displays. Notice how the text is two line and certain words are capitalized? Now, check this out! Here is a screen shot showing the dropdown menu that’s displayed when the browser window is tablet or phone sized. The markup to make this happen is quite simple…take a look. <li>     <a href="@Url.Action("what-is-crowdit","home")" title="Learn about what CrowdIt can do for your Small Business">         <span class="cdt-hidden-xs">WHAT<br /><small>is CrowdIt?</small></span>         <span class="cdt-visible-xs">What is CrowdIt?</span>     </a> </li> There is a single anchor tag in this example and only the spans change visibility based on browser width. I left them separate for readability and because I wanted to use the small tag; however, you could just as easily hide the “WHAT” and the br tag on small displays and replace them with “What “, consolidating this even further to text containing a single span. <span class=”cdt-hidden-xs”>WHAT<br /></span><span class=”cdt-visible-xs”>What </span>is CrowdIt? You might be a master of css and have a better method of handling this problem. If so, I’d love to hear about your solution…leave me some feedback! You’ll be entered into a drawing for a chance to win an autographed picture of ME! Yay!

  • When should method overloads be refactored?

    - by Ben Heley
    When should code that looks like: DoThing(string foo, string bar); DoThing(string foo, string bar, int baz, bool qux); ... DoThing(string foo, string bar, int baz, bool qux, string more, string andMore); Be refactored into something that can be called like so: var doThing = new DoThing(foo, bar); doThing.more = value; doThing.andMore = otherValue; doThing.Go(); Or should it be refactored into something else entirely? In the particular case that inspired this question, it's a public interface for an XSLT templating DLL where we've had to add various flags (of various types) that can't be embedded into the string XML input.

  • Strange behavior with gcc inline assembly

    - by Chris
    When inlining assembly in gcc, I find myself regularly having to add empty asm blocks in order to keep variables alive in earlier blocks, for example: asm("rcr $1,%[borrow];" "movq 0(%[b_],%[i],8),%%rax;" "adcq %%rax,0(%[r_top],%[i],8);" "rcl $1,%[borrow];" : [borrow]"+r"(borrow) : [i]"r"(i),[b_]"r"(b_.data),[r_top]"r"(r_top.data) : "%rax","%rdx"); asm("" : : "r"(borrow) : ); // work-around to keep borrow alive ... Another example of weirdness is that the code below works great without optimizations, but with -O3 it seg-faults: ulong carry = 0,hi = 0,qh = s.data[1],ql = s.data[0]; asm("movq 0(%[b]),%%rax;" "mulq %[ql];" "movq %%rax,0(%[sb]);" "movq %%rdx,%[hi];" : [hi]"=r"(hi) : [ql]"r"(ql),[b]"r"(b.data),[sb]"r"(sb.data) : "%rax","%rdx","memory"); for (long i = 1; i < b.size; i++) { asm("movq 0(%[b],%[i],8),%%rax;" "mulq %[ql];" "xorq %%r10,%%r10;" "addq %%rax,%[hi];" "adcq %%rdx,%[carry];" "adcq $0,%%r10;" "movq -8(%[b],%[i],8),%%rax;" "mulq %[qh];" "addq %%rax,%[hi];" "adcq %%rdx,%[carry];" "adcq $0,%%r10;" "movq %[hi],0(%[sb],%[i],8);" "movq %[carry],%[hi];" "movq %%r10,%[carry];" : [carry]"+r"(carry),[hi]"+r"(hi) : [i]"r"(i),[ql]"r"(ql),[qh]"r"(qh),[b]"r"(b.data),[sb]"r"(sb.data) : "%rax","%rdx","%r10","memory"); } asm("movq -8(%[b],%[i],8),%%rax;" "mulq %[qh];" "addq %%rax,%[hi];" "adcq %%rdx,%[carry];" "movq %[hi],0(%[sb],%[i],8);" "movq %[carry],8(%[sb],%[i],8);" : [hi]"+r"(hi),[carry]"+r"(carry) : [i]"r"(long(b.size)),[qh]"r"(qh),[b]"r"(b.data),[sb]"r"(sb.data) : "%rax","%rdx","memory"); I think it has to do with the fact that it's using so many registers. Is there something I'm missing here or is the register allocation just really buggy with gcc inline assembly?

  • Inconsistent email formatting with inline css created using Javamail

    - by user1816183
    Okay, so I have a program that sends an email when it is finished running. I use inline css to format the email. This was working up until yesterday however now I am seeing different formats depending on which email account I view the email in.

private Bullet bullet; private GameRenderer aims; // Ask for a reference to the Soldier when InputHandler is created. public InputHandler(Ball ball) { myBall = ball; } @Override public boolean touchDown(int screenX, int screenY, int pointer, int button) { return false;

} @Override public boolean touchDragged(int screenX, int screenY, int pointer) { return false; } @Override public boolean mouseMoved(int screenX, int screenY) { return false; } @Override public boolean scrolled(int amount) { return false; } } i am rendering all graphics in a GameRender class and a gameworld class if you need more info please let me know I am trying to make the array work but keep finding that when an array is initialized then the bullet fips back to the original and ends up being backwards???? and if I create an array I keep getting Exceptions throw??? Thank you for any help given.

  • An Epic Question "How to call a method when the page loads"

    - by Arunkumar Ramamoorthy
    Quite often, there comes a question in OTN, with different subjects, all meaning "How to call a method when my ADF page loads?". More often, people tend to take the approach of ADF Phase Listener by overriding before/afterPhase methods.In this blog, we will go through different options in achieving it.1. Method Call Activity as default activity in Taskflow :If the application is built with taskflows, then this is the best suited approach to take. 1.a. Calling a Data Control Method :To call a Data Control method (ex: A method in AMImpl exposed as client interface), simply Drag and Drop the method as Default Method Call Activity, then draw a control flow case from the method to your page. Once after this, drop the taskflow as region in main page. When we run the main page, the Method Call Activity would be called first, and then the page will be rendered.1.b. Calling a Method in Backing Bean: To call a method in the backing bean before pageload, we can follow the similar approach as above. Instead of binding the Method Call Activity to an action/method binding in pagedef, we bind to the method. Insert a Method Call Activity (and make it as default) from the Component Palette. Double click on to select a method to bind. This approach can also be used, to perform some action in backing bean along with calling a method Data Control (just need to add bindings code in backing bean to execute DC method). 2. Using invokeAction Executable :If the application is built with pages and no taskflows are involved, then this option can be taken into consideration.In the page definition of the page, add an invokeAction Executable and bind it to the method needed to be executed. 3. Using combination of Server and Client Listeners : If the page does not have any page definition, then to call a method in backing bean, this approach can be taken. In this, a serverListener would be added at the document level, which would be calling the method in backing bean. Along with this, a clientListener would be added with "load" type (i.e will be triggered when the page loads), which would queue a serverEvent to trigger the method. 4. Using Page Phase Listener :This should be the last resort. Care should be taken when using this approach since the Phase Listener would be called for each request sent by the client.Zeeshan Baig's blog covers this scenario.
