  • Return lines in input code causing gaps/whitespace between elements in output?

    - by Jenny Zhang
    I am trying to put images next to each other on a webpage. Here is my HTML: <img class="pt" src="Yellow Tulip.jpg" title="Yellow Tulip" alt="Yellow Tulip" /> <img class="pt" src="Pink Tulip.jpg" title="Pink Tulip" alt="Pink Tulip" /> <img class="pt" src="Purple Tulip.jpg" title="Purple Tulip" alt="Purple Tulip" /> However, on my webpage, this shows a gap between each image. I've noticed that once I remove the return line that makes the elements separate and readable and instead just put all the elements on one line, the gaps go away. <img class="pt" src="Yellow Tulip.jpg" title="Yellow Tulip" alt="Yellow Tulip" /><img class="pt" src="Pink Tulip.jpg" title="Pink Tulip" alt="Pink Tulip" /><img class="pt" src="Purple Tulip.jpg" title="Purple Tulip" alt="Purple Tulip" /> Is there anyway I can achieve the output of the latter but still have the code/input look like the former? I really like the readability that the return lines (enter spaces) bring to the code, but I don't want the whitespace it creates on the actual page. If someone could explain why this is and/or how to fix it, I'd be really grateful! :)

  • How to convert Vector Layer coordinates into Map Latitude and Longitude in Openlayers.

    - by Jenny
    I'm pretty confused. I have a point: x= -12669114.702301 y= 5561132.6760608 That I got from drawing a square on a vector layer with the DrawFeature controller. The numbers seem...erm...awfull large, but they seem to work, because if I later draw a square with all the same points, it's in the same position, so I figure they have to be right. The problem is when I try to convert this point to latitude and longitude. I'm using: map.getLonLatFromPixel(pointToPixel(points[0])); Where points[0] is a geometry Point, and the pointToPixel function takes any point and turns it into a pixel (since the getLonLatFromPixel needs a pixel). It does this by simply taking the point's x, and making it the pixels x, and so on. The latitude and longitude I get is on the order of: lat: -54402718463.864 lng: -18771380.353223 This is very clearly wrong. I'm left really confused. I try projecting this object, using: .transform(new OpenLayers.Projection("EPSG:4326"), map.getProjectionObject()); But I don't really get it and am pretty sure I did it incorrectly, anyways. My code is here: http://pastie.org/909644 I'm sort of at a loss. The coordinates seem consistent, because I can reuse them to get the same result...but they seem way larger than any of the examples I'm seeing on the openLayers website...

  • How to set default view in OpenLayers, WITHOUT restricting bounds?

    - by Jenny
    Based on samples, I can see that you can set a default view in OpenLayers by saying something along the lines of: var bounds = new OpenLayers.Bounds(-125, 25, -65, 50); var map = new OpenLayers.Map('map', {restrictedExtent: bounds }); However, this also (as the name implies), restricts me to be able to ONLY navigate within these bounds. I can zoom out and see things outside of these bounds, but I can't then zoom back onto them, or scroll to them. I've tried not having any restrictedExtent (or making it the entire map), but then I can't get it to focus on the area I want. I tried using: map.setCenter(new OpenLayers.LonLat(0,0), 3); console.log(map.getCenter()); To set the zoom and the center...but it doesn't seem to do ANYTHING, other than set the variable "center" which I can then read from map.getCenter() (if I don't set it, it's null, if I do set it, I can see it...but the map itself stays fully extended and it's center doesn't seem to change at all...) The Map layer I am using is: OpenLayers.Layer.OSM.Mapnik with displayOutsideMaxExtent set to true... I'm really at a loss here. My goal is to have a default region of the world zoomed in to and in view (such as the United States), with the option of viewers being able to go outside the default to view things.

  • HTML Table: How to resize data cells when already specified "colspan"?

    - by Jenny
    I have tabular data to display, which has a meaning to both rows and columns. Columns are time blocks, rows are days. A particular datacell is confined to a single day, but can be in multiple time block. To show this, I am using the colspan tag. <div id = "GuideTable"> <table> <tr> <td colspan = 3> </td></tr></table> </div> Or Whatever. I'm trying to apply CSS formating to the entire table, and for changing colors, etc, things are fine, but wanting to have a consistent width is where I am running into problems. Right now, each data cell's width seems tied to the maximum width in its column (everything auto lines up). Some columns are itty bitty, others are huge. I'm trying to make columns consistently sized (even if that means every column is as big as the biggest column needs to be), but setting an individual datacells width (either via css or in the tag itself) is getting me nowhere. I'm thinking maybe the colspan tag is overriding my manual width? If that's the case, how can I change the width of a column as a whole, especially since they aren't explicitly defined? (CAN you explicitly define columns?) Examples of the CSS I'm using: #GuideTable td{ background:#ffffff; border-style: solid; border-width: 1px; width: 100px; }

  • OpenLayers eraseFeatures doesn't erase features from map screen.

    - by Jenny
    I'm using OpenLayers, and have a layer for my Map, and a single Vector Layer. In this vector layer, I am using the DrawFeature control to draw a square. I have a listener waiting for a feature to be added, and then deleting any existing features (I only want one square at a time), like so: polygonLayer.events.register("beforefeatureadded", feature, function(evt){ console.log("Clearing existing polygons"); console.log(polygonLayer.features.length); polygonLayer.destroyFeatures(); polygonLayer.redraw(); });//end attempt at events registration When I check my layer.features.size, I can see that it's always 1, just like I expect, but the squares on the screen are still displayed. Even when I call .redraw() on the layer, the squares are still there. Is there some extra step I'm missing? Edit: You can find my code here: http://pastie.org/909644 Edit: Just realized: If I draw a square from previously existing coordinates, I can clear it just fine. It seems to be just the squares drawn from the controller that are an issue?

  • Accessing TextView from another class

    - by Jenny
    I've got my main startup class loading main.xml but I'm trying to figure out how to access the TextView from another class which is loading information from a database. I would like to publish that information to the TextView. So far I've not found any helpful examples on Google. EDIT: This is my class that is doing the Database work: import android.widget.TextView;import android.view.View; public class DBWork{ private View view; ... TextView tv = (TextView) view.findViewById(R.id.TextView01); tv.setText("TEXT ME") Yet, everytime I do that I get a nullpointerexception

  • how to temporarily set makeprg in vim

    - by Haiyuan Zhang
    In the normal case I use vim's make utility I will set makeprg to the Makefile of the project I'm currently working for. Since usually the project will last for weeks or even longer, I don't need to change the setting of makeprg very often . But sometimes I need to write some "foobar" code either for practicing my c++ skill or for prototyping some primitive ideas in my mind. So whenever I switch to the "foobar" mode of vim usage, I need to comments the original makeprg setting add the new setting as following : au FileType c set makeprg=gcc\ % au FileType cpp set makeprg=g++\ % which is really very very inconvenient . when I back to the "normal project mode" of vim usage, I need to change back to the original setting . back and forth .... what I want to know from you guys is that : is it possible to make the setting of makeprg temporarily . for example , define a function in which first set a local value of makeprg and then call make before return form the function call automatically restore makeprg to the value before the function call.

  • jquery dynatree class methods

    - by Jj Zhang
    I'm a new user of dynatree plugin. When I read the documentation, I found the list of tree and node class member functions, such as tree.getRoot(), node.countChildren(). However, when I tried to use them, it complained that no such methods were found. Here is a sample code I am testing with: var tree = ("#test").dynatree(treeData); var rootNode = tree.getRoot(); //not working var rootNode2 = ("#test").dynatree("getRoot"); //this works var numChildren = rootNode2.countChildren(); //not working Help please. Thanks. -JJ

  • how to manage a "resource" array efficiently

    - by Haiyuan Zhang
    The senario of my question is that one need to use a fixed size of array to keep track of certain number of "objects" . The object here can be as simply as a integer or as complex as very fancy data structure. And "keep track" here means to allocate one object when other part of the app need one instance of object and recyle it for future allocation when one instance of the object is returned .Finally ,let me use c++ to put my problme in a more descriptive way . #define MAX 65535 /* 65535 just indicate that many items should be handled . performance demanding! */ typedef struct { int item ; }Item_t; Item_t items[MAX] ; class itemManager { private : /* up to you.... */ public : int get() ; /* get one index to a free Item_t in items */ bool put(int index) ; /* recyle one Item_t indicate by one index in items */ } how will you implement the two public functions of itemManager ? it's up to you to add any private member .

  • why can't I comment lines in visual mode

    - by Haiyuan Zhang
    I want to comment several lines in my .vimrc, the usual way I do it is :x,ys/^/"/ and x stands for the start line number and y stands for the line number of the last line. I read some post which said in visual mode this task can be done by the following step: 1 Select your lines with VISUAL BLOCK 2 press I to insert before all highlighted lines. 3 type your comment charact , in this case should be " 4 then ESC I fllowed the above steps and met met problems in step 2 . the thing is when I select the lines in Visual mode and press I , vim ( I use version7.2) go back to insert mode and the cursor back to the start of the first line. so if you continue to do the step 3 and step 4, you end up in just inserting " at the start the first line , far from what I want to achieve. so could you point out what's wrong with the recipe ? thanks in advance

  • how to manage vim plugin

    - by Haiyuan Zhang
    I want to know how do you manage your vim plugins. As it is, One of the biggest fun of using is that one can easily try many interesing new plugins, just download it and unzip it in under ~/.vim. But if you try too often and try too much, you might get trouble as confilct of key mapping , in compatitble script version, dpendency between different plugin ..... Then you want to remove some plugin ,kind of like rollback your vim to a sound condition. But, the rollback could be very painful . cus for some "giant" plugin, like perl-support ( it's great plugin, anyway), will consist of many vim scripts which spread in different dirctories. To remove single one giant plugin will be anoying, not too mention if you remvoe many plugin at one time. In a word , I'm looking for good practice for managing vim plugins.

It's will be very tedious that when you want to bind a link local adress to a ipv6 socket you need to the set sin6_scope_id field of sockaddr_in6 struct as well. I'm wondering if someone can provide a good practise like solution here for me or anyone who interested in this topic to learn from.
