Drupal Navigation Conundrum

- by Vecta

I'm attempting to set up navigation withing a Drupal site and am having a bit of trouble. I'm trying to have a series of pages that each have a set number of sub-pages. These pages will need to link to one another. All pages will contain similar content. For instance: Page 1 will have sub-pages a, b, c, d, e, and f all with content related to the topic of page 1 Page 2 will have sub-pages a, b, c, d, e, and f with content related to the topic of page 2 I'd like these links to appear in a horizontal nav bar on each page. Is it possible to accomplish this using the book module? I've also read some information about the taxonomy menu module that sounds promising, but I'm not really sure how that would work. What route should I look into? Thanks for any input!

Design advices for quick navigation between view

- by Thomas Joulin

Usually, when a View requires a lot of bindings, or some UI Elements like a Bing Map, it takes a "while" to load (like between half a second and a second). I don't want a delay between a "tap" action (like tapping an element on a ListBox) and the navigation action (displaying a new page). I don't mind displaying the page progressively. For example, for a Bing Map, I don't mind displaying a black page with only a title, and a second later, having the Map appear. What are the best practices ? It could post a sample if i'm not clear enough

jQuery changing css on navigation when div # scrolls into view

- by Jonny Wood

I'm looking to recreate the effect used on this site: http://www.brizk.com/ The site uses one large page that scrolls down. As you scroll down and pass different sections the menu navigation on the left changes css class to "current" as the corresponding div comes into view. I presume this can be done with jQuery using $(window).height(); I'm fairly new to jQuery and what I want to write is something like this (in laymans terms): Get height of browser window – if div#content1 is 100px from top and/or 200px from bottom change menu a#link1 to '.current' – else remove .current from all menu a links ... and repeat for 4 different content divs. Can anyone point me in the right direction..? Thanks.

UINavigationController doesn't fully push view and only changes the Navigation toolbar to the next v

- by user284757

So I have an iPhone application that utilizes a UINavigationController for setting up the views. When the application first starts, it presents the user with a UITableViewController and the user can select an item and it will push another view. Now I have it set so that my app remembers the user's last selection and automatically selects it and loads the correct view controller. The only problem is that I am experiencing a really weird glitch when I load the next view automatically.. When the view is pushed, the navigation toolbar will change so that a back button directed to the previous view is showing but it won't display the next view. It will instead keep showing the table view and I can interact with it as well. I can press the back button and it will change the toolbar back and the tableview is still shown. Then when I select an item it loads the view just fine. Thanks for the help.

Problem in building a tab bar inside navigation controller

- by Heba

Hello Everyone! I am really frustrated and I rally hope that you will help me to solve this problem! I'm trying to build a tab bar inside a navigation controller. I used this template provided by WiredBob. My problem is that I want to add more bar items to the tab bar, but I keep getting crash! From the log: 2010-05-24 00:15:43.469 NavTab[9315:207] * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] loaded the "AnnView" nib but didn't get a UITableView.' Also, I tried to fix the size of the a view in IB to fit in with the tab bar, but I couldn't! It was unchangeable. Thanks in advance :-)

How to determine character's foot contact point on a uniform triangle mesh terrain?

- by xenon

For a terrain that is modelled by a heightmap with a uniform triangle mesh, what are some techniques I could use to determine the contact point of the foot of a character standing on the terrain? Since the terrain's Y values are altered by the heightmap, they won't be flat any more. As the character moves on the terrain, it has to know at which values of Y-value its foot should be. Conceptually, what are some methods and techniques to determine the contact point of the character's foot standing on the terrain?

How can I make Maya export a mesh as double-sided?

- by bobobobo

I'm exporting from Maya 2009 to OBJ. The mesh I'm exporting has in it's Render Stats "Double Sided" checked, but when the polygon is exported, only a single side is actually exported. What really needs to happen is for each polygon that is double sided, two polygons need to be exported, facing in opposite directions.. I can do this manually, but is there a way to make the OBJ exporter do it for me?

Jqgrid: navigation based on the selected row

- by bsreekanth

Hello, I was trying to enable navigation based on a selected row. So, the user select a row from jQgrid, and when press the show (is there a show button for the grid, I saw edit, add etc), it needs to go to a new page based on the url (part of the row). $(document).ready(function () { function getLink() { // var rowid = $("#customer_list").jqGrid('getGridParam', 'selrow'); var rowid = $("#customer_list").getGridParam('selrow'); var MyCellData = $("#customer_list").jqGrid('getCell', rowid, 'dataUrl'); return MyCellData; } $("#customer_list").jqGrid({ url:'mytestList', editurl:'jq_edit_test', datatype: "json", colNames:['Call Id','Title','dataUrl'], colModel:[ {name:'callId', width:80, search:false }, {name:'title', width:200, sortable:false }, {name:'dataUrl',hidden:true} ], rowNum:10, sortname:'lastUpdated', sortorder: 'desc', pager:'#customer_list_pager', viewrecords: true, gridview: true }).navGrid('#customer_list_pager', {add:true,edit:true,del:false,search:true,refresh:true}, {closeAfterEdit:true, afterSubmit:afterSubmitEvent }, // edit options {addCaption:'Create New something', afterSubmit:afterSubmitEvent, savekey:[true,13]}, // add options {afterSubmit:afterSubmitEvent} // delete options ); $("#customer_list").jqGrid('filterToolbar'); }); so, the url is passed for each row as dataUrl. I'm trying to read it and set to the button. Whn debug through firebug, the rowid was 223 (there were only 12 rows in the grid), and the cell value is empty. Currently the button is kept outside the grid, but it may better to be it part of the vavGrid thanks.

Adding a navigation bar to a web view in a tab bar app

- by Henrik Erlandsson

I've built the tab bar application in IB, with three tabs. The third tab happily displays a UIWebview where you can browse. The only thing missing is a back button, as not all web pages supply such a link. I need a navigation bar hooked up properly to the correct classes. I'm still a bit unsure about exactly how the hierarchy should look in interface builder and how to hook it up properly. Currently, the third tab is hooked up to a referencing outlet called 'webnews' in the class 'thirdviewcontroller', and the UIWebView (under a normal IUView in the hierarchy, which in turn is under the third tab bar controller) is connected to the webnews outlet. How do I make the navbar control the webview, and do I add code to the thirdviewcontroller.m that lets the navbar on the view control the webview 'back' function? What do I hook up as the delegate for it? Currently I have an app delegate, but that's hooked up to the tab bar. I'm not really after specific code as much as a general 'how it works' clue :) (Unless I can just add the navbar dynamically to the functioning app... but I don't think addSubView on viewWillAppear {} in thirdviewcontroller.m will create the proper functionality?) If I were to guess at the simplest solution, I'd guess create a navbarcontroller.h/.m, slap a navbar on the view in IB, connect the third tab to navbarcontroller, connect the navbar to the webview (?) and move the webnews outlet to navbarcontroller.h, and connect the webview to it. But I don't quite have the nerve to try, better to ask advice first.

Wordpress dynamic navigation function for highlighting single post tabs

- by user269959

I am trying to write a function that i can reuse in my wordpress themes that will allow me to build robust dynamic navigation menus. Here is what i have so far: function tab_maker($page_name, $href, $tabname) { //opens <li> tag to allow active class to be inserted if tab is on proper page echo "<li"; //checks that we are on current page and highlights tab as active if so if(is_page($page_name)){ echo " class='current_page_item'>"; } //closes <li> tab if not active else { echo ">"; } //inserts the link as $href and the name of the tab to appear as $tabname then closes <li> echo "<a href=$href>$tabname</a>"; echo "</li>"; } This code works as expected except i cant enable it to highlight for a single blog post as the page names are dynamic. I know about the wordpress function is_single() which ive used to implement this feature in previous nav menus but i cant find a way to integrate it into this function. appreciate any help!

Custom UIView using CALayers disappears after 180º rotation or navigation controller pop

- by Steve Madsen

I have a created a custom UIView subclass that is exhibiting some strange behavior. It is a spinning wheel selector, and for performance reasons it is drawn entirely into two CALayer instances. The bottom layer is the wheel itself, which is rotated using setAffineTransform: according to touches. The top layer is eye candy. drawRect: is fairly simple. If the control hasn't been drawn yet (or it's been invalidated), it calls a method that creates the images and assigns them to the layer contents property. - (void) drawRect:(CGRect)rect { if (imageLayer == nil) { [self drawIntoImageLayer]; } [self updateWheelRotation]; } When the view controller using this view first appears, everything is fine. There are two instances where the view completely disappears, however: If the device is rotated a full 180°. After a view controller is popped off the navigation stack and the view becomes visible again. drawRect: is not called either time. Interestingly enough, it IS called after a 90° orientation change, and that causes the view to re-appear. How can I ensure that a custom view using CALayers is redrawn properly in these situations?

Wizard style navigation, dismissing a view and showing another one

- by Robin Jamieson

I'm making a set of screens similar to a wizard and I'd like to know how to make a view dismiss itself and its parent view and immediately show a 'DoneScreen' without worrying about resource leaks. My views look like the following: Base -> Level1 -> DoneScreen -> Level2 -> DoneScreen The Level1 controller is a navigation controller created with a view.xib and shown with [self presentModalViewController ...] by the Base controller. The Level1 controller is also responsible for creating the 'DoneScreen' which may be shown instead of the Level2 Screen based on a certain criteria. When the user taps a button on the screen, the Level1 controller instantiates the the Level2 controller and it displays it via [self.navigationController pushViewController ..] and Level2 controller's view has a 'Next' button. When the use hits the 'Next' button in the Level2 screen, I need to dismiss the current Level2's view as well as the Level1's view and display the 'DoneScreen', which would have been created and passed in to the Level2 controller from Level1. (partly to reduce code duplication, and partly to separate responsibilities among the controllers) In the Level2 controller, if I show the 'DoneScreen' first and dismiss itself with [self.navigationController popViewControllerAnimated:YES]; then the Level1 controller's modal view is still present above the 'Base' but under the Done screen. What's a good way to clear out all of these views except the Base and then show the 'DoneScreen'? Any good suggestions on how to get this done in a simple but elegant manner?

Sencha touch 2/ app workflow with navigation view

- by eplatonov

I am trying to understand how can I implement the same functionality which provides navigation view in sencha touch 2, but .... Each item of the 'Ext.NavigationView' component should have it's own unique set of 'navigationBar' elements. I mean set of buttons, for example. I know that I can do something like this: this.getMain().getNavigationBar().rightBox.removeAll(); this.getMain().getNavigationBar().rightBox.add(this.getSettingButton()); //where 'getSettingButton' predefined by me a button And do this action each time when 'push' event happens (clear 'navigationBar' and add appropriate set of buttons) Of course, I even can implement 'Ext.Panel' with 'layout: card' and set of 'Ext.panel' elements in the 'items' property, each of which will be have unique 'toolbar'. To control the behavior I can use 'setActiveItem' method. But, I think each of these approaches is a bit weird, isn't it? I expected that would be much more natural approach to implement it. Most likely I don't know what I need. Confirm my doubts. What is the best way to do it.

Problem pushing multiple view controllers onto navigation controller stack

- by Jim

Hi, I am trying to push three view controllers onto the navigation controller. [self.navigationController pushViewController:one animated:YES]; [self.navigationController pushViewController:two animated:YES]; [self.navigationController pushViewController:three animated:YES]; The desired behavior is that view three will show, and when the back button is pressed it will go to view two and then to view one... What actually happens is that view one is visible and pressing back goes to view two and then back again it goes to view one. Which is to say that view one is shown instead of view three. Very strangely, looking at the viewController array of the navigationController after the calls above show the right entries, and looking at the visibleViewController property shows that it has view three in it... even though view one is visible. If i navigate to a sub view from the visible view one (that shows in the place of view three) and press back from that sub view... it goes to view three. It looks like it is showing view one, but knows it is on view three... I am completely confused... any ideas? Jim

Assign click event to addon icon on navigation bar

- by Charsee

We have created a chrome extension for our app. Where we call a METHOD from a "js file" on CLICK event of the "extension icon" placed on the navigation bar. For this we use message passing between the app.js (file containing the METHOD to be called on icon click) and background.html (using a js file included in this html). The script used to pass message is:(from background.html) chrome.browserAction.onClicked.addListener(function (tab) { chrome.tabs.sendMessage(tab.id, "showPopup"); }); and to listen the message :(in app.js) chrome.extension.onMessage.addListener(function(request) { if (request === "showPopup") { showPopup(); } }); The click event works as expected. But now we want to do same thing in mozilla extension. and we can't pass message to app.js on the click of the icon,so that it can execute the containing methods. We have also added the app.js using pageMod, something like this exports.main = function(options, callbacks) { pageMod.PageMod({ include: ["*"], contentScriptWhen: 'start', contentScriptFile: [data.url('jquery-1.7.1.min.js'),data.url('app.js')] }); createAndAddNavBarButton(); }; function createAndAddNavBarButton() { var navBar = document.getElementById('nav-bar');//assume document has been defined if (!navBar){return;}; var nbBtn = document.createElement('navbaricon'); nbBtn.setAttribute('id', 'navButton'); nbBtn.setAttribute('image', data.url('icon_16.png')); nbBtn.onclick = function(){ showPopup(); return true; } navBar.appendChild(btn); } But the click event does nothing and showPopup() is undefined. When a new page loads event associated with it in the app.js executes without any error but the click event doesn't work. Is there a method from where we can assign click event directly to this icon, as we have done in the case of chrome extension.

create dynamic navigation from xml file in flash cs3

action script newbie here :-) What I want to do is this, hand an xml file to a swf and have the swf generate a dynamic text box and button for each of the links in the xml file a rudimentary navigation here's the xml <?xml version="1.0" encoding="UTF-8"?> <page> <page name="Page Name 1" url="/page-1/" /> <page name="Page Name 2" url="/page-2/" /> <page name="Page Name 3" url="/page-3/" /> <page name="Page Name 4" url="/page-4/" /> </page> and in my fla I have a button in my library named 'nav_button' there's a layer named actions and in frame 1 I have this var xml:XML; var xmlList:XMLList; var xmlLoader:URLLoader = new URLLoader(); var button:Button = new Button(); xmlLoader.load(new URLRequest("links.xml")); xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded); function xmlLoaded(event:Event):void { xml = XML(event.target.data); xmlList = xml.children(); trace(xml.length()); for(var i:int = 0; i < xmlList.length(); i++) { button = new Button(); button.x = 25; button.y = i * 50 +25; addChild(button); } } the xml imports fine, but when it comes to the for loop and adding the buttons and text boxes to the stage, I'm toast

Dynamically resizing navigation div to main content

- by theZod

Greetings and Hello I am trying to put together a wordpress site, now because the content in the main div is going to be a different height with every page I need the navigation sidebar to stretch to the same height. So with a little javascript tom-foolery I can get the sidebar to be the same height with the following code function adjust(){ hgt=document.getElementById('content').offsetHeight; document.getElementById('sidebar').style.height=hgt+'px'; } window.onload=adjust; window.onresize=adjust; Now that's all good for a long page but if the content is smaller then the sidebar stuff gets all messy. So I have tried an if statement like so function adjust() { if (document.getElementById('content').style.height < document.getElementById('sidebar').style.height){ hgt=document.getElementById('content').offsetHeight; document.getElementById('sidebar').style.height=hgt+'px'; else hgt=document.getElementById('sidebar').offsetHeight; document.getElementById('content').style.height=hgt+'px'; } } window.onload=adjust; window.onresize=adjust; But that just doesn't do anything, so any ideas whats going on?

Black Corners On Grouped UITableViewCells Only After Navigation Pops

- by coneybeare

I am not graphics expert but I somehow managed to make some good looking custom grouped UITableViewCells by setting the background view to a backgroundView with some CG code. In all SDK's up to 3.1.3 (maybe 3.2... I haven't tested on the iPad) this was working great, but I think a more recent SDK has introduced a change in the way graphics are cached offscreen. Upon first render, everything is great: The drawing is fine and the corners are transparent. If I push a couple of view controllers on the navigation stack and come back, there are now black corners that appear in the views: BEFORE && AFTER I have tons of code, most of which is written up here. I have tried tweaking to the best of my ability, looking at the docs for applicable changes, but after at least 8 hours in I still cannot find what might cause this. I have tried setting every view I can think of to be backgroundColor=clearColor and opaque=NO What else am I missing? Any debugging tips? UPDATE: I have some debug code in viewDidAppear that prints the backgroundColor and class description of all the subviews. - (void)debugView:(UIView *)view { DebugLog(@"%@ - %@", view.backgroundColor, [[view class] description]); for (UIView* child in view.subviews) { [self debugView:child]; } } - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [DownloadController.networkQueue setSuspended:NO]; for (TTTableViewCell *cell in [self.tableView visibleCells]) { [cell debugView:cell]; } } With this code, I inspect the backgroundColor settings of the cell views on first load, when it is fine, and then again after coming back. There are some differences, but all the colors are still set to be clear. This leads me to believe the issue is underneath the UITableViewCell. UPDATE 2: I have created a simple sample application to highlight the problem here

PHP Multiple navigation highlights

- by Blackbird

I'm using this piece of code below to highlight the "active" menu item on my global navigation. <?php $path = $_SERVER['PHP_SELF']; $page = basename($path); $page = basename($path, '.php'); ?> <ul id="nav"> <li class="home"><a href="index.php">Home</a></li> <li <?php if ($page == 'search') { ?>class="active"<?php } ?>><a href="#">Search</a></li> <li <?php if ($page == 'help') { ?>class="active"<?php } ?>><a href="help.php">Help</a></li> </ul> All works great but, on a couple of pages, I have a second sub menu (sidebar menu) within a global page. I basically need to add a OR type statement into the php somehow, but I haven't a clue a how. Example of what i mean: <li <?php if ($page == 'help') OR ($page == 'help-overview') OR ($page == 'help-cat-1') { ?>class="active"<?php } ?>><a href="#">Search</a></li> Thanks!

How to export 3D models that consist of several parts (eg. turret on a tank)?

- by Will

What are the standard alternatives for the mechanics of attaching turrets and such to 3D models for use in-game? I don't mean the logic, but rather the graphics aspects. My naive approach is to extend the MD2-like format that I'm using (blender-exported using a script) to include a new set of properties for a mesh that: is anchored in another 'parent' mesh. The anchor is a point and normal in the parent mesh and a point and normal in the child mesh; these will always be colinear, giving the child rotation but not translation relative to the parent point. has a normal that is aligned with a 'target'. Classically this target is the enemy that is being engaged, but it might be some other vector e.g. 'the wind' (for sails and flags (and smoke, which is a particle system but the same principle applies)) or 'upwards' (e.g. so bodies of riders bend properly when riding a horse up an incline etc). that the anchor and target alignments have maximum and minimum and a speed coeff. there is game logic for multiple turrets and on a model and deciding which engages which enemy. 'primary' and 'secondary' or 'target0' ... 'targetN' or some such annotation will be there. So to illustrate, a classic tank would be made from three meshes; a main body mesh, a turret mesh that is anchored to the top of the main body so it can spin only horizontally and a barrel mesh that is anchored to the front of the turret and can only move vertically within some bounds. And there might be a forth flag mesh on top of the turret that is aligned with 'wind' where wind is a function the engine solves that merges environment's wind angle with angle the vehicle is travelling in an velocity, or something fancy. This gives each mesh one degree of freedom relative to its parent. Things with multiple degrees of freedom can be modelled by zero-vertex connecting meshes perhaps? This is where I think the approach I outlined begins to feel inelegant, yet perhaps its still a workable system? This is why I want to know how it is done in professional games ;) Are there better approaches? Are there formats that already include this information? Is this routine?

Attaching new animations onto skeleton via props, a good idea?

- by Cardin

I'm thinking of coding a game with an idea of mine. I've coded 2D games before, but I'm new to 3D programming, so I'd like to ask if this idea of mine is feasible or out of my depth. I'm making a game where there are many different characters for the player to choose from (JRPG style). So to save time, I have an idea of creating many different varied characters using a completely naked body mesh and animation skeleton, standardised across all characters. For example, by placing different hair, boots, armor props on the character mesh, new characters can be formed. Kinda like playing dress-up with a barbie doll. I'm thinking this can be done by having a bone on the prop that I can programmically attach to the main mesh. Also, I plan to have some props add new animations to the base skeleton, so equipping some particular props would give it new attack, damage, idle animations. This is because I can't expect the character to have the same swinging animation if he had a big sword or an axe. I think this might be possible if the prop has its own instance of the animation skeleton with just only the new animations, and parenting the base body mesh to this new skeleton. So all the base body mesh has are just the basic animations, other animations come from the props. My concerns are, 1) the props might not attach to the mesh properly and jitter a lot, 2) since prop and body are animated differently, the props and base mesh will cause visual artefacts, like the naked thighs showing through the pants when the character walks, 3) a custom pipeline have to be developed to export skeletons without mesh, and also to attach the base body mesh to a new skeleton during runtime in the game. So my question: are these features considered 'easy' to code? Or am I trying to do something few have ever succeeded with on their own? It feels like all these can be done given enough time and I know I definitely have to do a bit of bone matrix calculations, but I really don't want to drag out the development timeline unnecessarily from coding mathematically intense things or analyzing how to parse 3D export formats. I'm currently only at the Game Design stage, so if these features aren't a good idea, I can simply change the design of the game. (Unrelated to question) I could always, as last resort, have the characters have predetermined outfit and weapon selections so as to animate everything manually.

Maze Navigation in Player Stage with Roomba

Here is my code: /* Scott Landau Robot Lab Assignment 1 */ // Standard Java Libs import java.io.*; // Player/Stage Libs import javaclient2.*; import javaclient2.structures.*; import javaclient2.structures.sonar.*; // Begin public class SpinningRobot { public static Position2DInterface pos = null; public static LaserInterface laser = null; public static void main(String[] args) { PlayerClient robot = new PlayerClient("localhost", 6665); laser = robot.requestInterfaceLaser(0, PlayerConstants.PLAYER_OPEN_MODE); pos = robot.requestInterfacePosition2D(0,PlayerConstants.PLAYER_OPEN_MODE); robot.runThreaded (-1, -1); pos.setSpeed(0.5f, -0.25f); // end pos float x, y; x = 46.0f; y = -46.0f; boolean done = false; while( !done ){ if(laser.isDataReady()) { float[] laser_data = laser.getData().getRanges(); System.out.println("== IR Sensor =="); System.out.println("Left Wall Distance: "+laser_data[360]); System.out.println("Right Wall Distance: " +laser_data[0]); // if laser doesn't reach left wall, move to detect it // so we can guide using left wall if ( laser_data[360] < 0.6f ) { while ( laser_data[360] < 0.6f ) { pos.setSpeed(0.5f, -0.5f); } } else if ( laser_data[0] < 0.6f ) { while(laser_data[0<0.6f) { pos.setSpeed(0.5f, 0.5f); } } pos.setSpeed(0.5f, -0.25f); // end pos? done = ( (pos.getX() == x) && (pos.getY() == y) ); } } } } // End I was trying to have the Roomba go continuously at a slight right curve, quickly turning away from each wall it came to close to if it recognized it with it's laser. I can only use laser_data[360] and laser_data[0] for this one robot. I think this would eventually navigate the maze. However, I am using the Player Stage platform, and Stage freezes when the Roomba comes close to a wall using this code, I have no idea why. Also, if you can think of a better maze navigation algorithm, please let me know. Thank you!
