  • Cocoa Touch: Why doesn't UINavigationController render 'Back' button?

    - by Joshua
    When I push a view controller it animates properly and slides in, the only problem is that no 'Back' button is rendered up top.The back button is still there, I can still tap it, it just doesn't render on the screen. This behavior is identical in both the simulator and on multiple devices. Is this a known issue or bug? Using 3.1.3 of the iPhone SDK. More information: It renders it for further levels, just not on the second level of nav controller. So Main Page (No back button - OK). Second level page (back button, but doesn't render - not OK). Third level page (Back button there and rendering - OK).

  • Image inside a button not positioned correctly in Firefox

    - by Dominic Rodger
    I have the following markup: <p class="managebox"> <button value="Add page"> <img src="page_add.png" alt="Add more content" /> Add Page </button> </p> And the following CSS: p.managebox { position: relative; } p.managebox button { display: block; padding: 5px 7px 4px 30px; position: relative; } p.managebox button img { position: absolute; left: 7px; } In IE 8 I get this: In Chrome 4.0 I get this: In Firefox 3.6 I get this: Does anyone know what I'm doing wrong? One thing I've just realised that may be relevant - if I use an a instead of button, it works fine.

  • iPhone: Add background button to view when UITableView has no cells

    - by Nic Hubbard
    I have a UITableViewController, when there is no data to populate the UITableView, I want to add a button, which uses an image. So, rather than the user seeing a tableview with no records, they will see an image that says, "No records have been added, Tap to add one", then they click and we create a new one. I assumed I would just hide the UITableView, then create the button, but I never see the button. Here I am using: if ([[fetchedResultsController sections] count] == 0) { self.tableView.hidden = YES; // Create button w/ image UIButton * btn = [UIButton buttonWithType:UIButtonTypeRoundedRect]; btn.frame = CGRectMake(0, 0, 100, 50); [btn setImage:[UIImage imageNamed:@"no-rides.png"] forState:UIControlStateNormal]; [self.view addSubview:btn]; } Ideas on why I would never see the button? When I show this view, it seems to have a transparent background for a second, then changes white...

  • Setting button width with fx:Style

    - by Kamo
    I have 4 buttons, all of them have the same width. <s:Button id="btn1" width="{btnWidth}" /> <s:Button id="btn2" width="{btnWidth}" /> <s:Button id="btn3" width="{btnWidth}" /> <s:Button id="btn4" width="{btnWidth}" /> Is it possible to set their width with Style, something like this: s|Button{ width: btnWidth; } I tried it, but auto-complete isn't working, which leads me to think that there's something wrong with the syntax. Basically my goal is to not have the width property set specifically for all 4.

  • jQuery hover() event on div element within a button element

    - by jakeisonline
    I can't seem to get jQuery to notice the div within the following markup <button class="button submit positive right" id="omnisubmit" type="submit"> <div class="label">Submit</div> <div class="controller">&nbsp;</div> </button> And here is the jQuery I'm currently using: $("button#omnisubmit div.controller").hover(function () { console.log("Hover..."); }); However, jQuery doesn't seem to pick up when the mouse is hovering over that div, $("button#omnisubmit div.controller").hover( works correctly, of course. I have a feeling it's because putting divs inside buttons may not be standard HTML?

  • Homework - C# - Creating an object instance with a button click

    - by Erica
    I'm new to learning Windows Programming with C#. My current assignment is to create a very simple bank account program: The user enters the accountholder name, account number and beginning balance, then presses a "Continue" button to work with that account by making deposits and withdrawals. I wrote a separate "BankAccount" class with the required data members and methods. I've put the code for the creation of the BankAccount object in the Continue button click event BankAccount currentAccount = new BankAccount(acctName, acctNum, beginningBalance); But that seems to make it local to that method only, and currentAccount is not recognized when I'm programming the click event for the "Record Transactions" (deposits and withdrawals) button. How and where should the creation of the BankAccount object be coded in order for it to be created when the "Continue" button is clicked and also recognized in the "Record Transactions" button click event? Please let me know if any clarification is needed, or if you need to see part or all of my code.

  • ASP.NET Radio Button State and Back Key

    - by Dave S
    When using the browser back key on a page with radio buttons and using auto-postback, the state of the buttons (checked) stays the same while other parts of the page do not. This results in a situation where button two is checked and the cached page (because of server-side logic) displays a message that button 1 is checked. What is the best way to handle this situation? The following code example exhibits this behavior: [Form:] <asp:RadioButton ID="rb1" runat="server" AutoPostBack="true" Text="Button1" OnCheckedChanged="rb_CheckedChanged" GroupName="rbgroup" Checked="true" /> <br /> <asp:RadioButton ID="rb2" runat="server" AutoPostBack="true" Text="Button2" OnCheckedChanged="rb_CheckedChanged" GroupName="rbgroup" /> <br /> <hr /> <asp:Label ID="lbl1" runat="server">Button 1</asp:Label> [Code Behind:] protected void rb_CheckedChanged(object sender, EventArgs e) { if (rb1.Checked == true) lbl1.Text = "Button 1"; else lbl1.Text = "Button 2"; }

  • Calling a function when using <button> tag with jQuery Mobile

    - by u2sonderzug
    I already asked a similar question for buttons in tags, but I find that solution doesn't work using tags. So, if I am using a script that references jQuery Mobile I have the following line: <button id="buttonAnswer1" data-inline="true">Click me</button> How would I add a listener for when this button is clicked and lets say call the hello() function? i.e. <button id="buttonAnswer1" data-inline="true">Click me</button> <script> function hello(){ console.log("hello world"); } </script>

  • Hide or display a button according to row count of a table

    - by kawtousse
    Hi, i have a HTML table and a button send. First of all the send button must have this style: style.display="none". But if the table has at least one row the button should be displayed (block/inline); I still have no idea how to relate between the table and the button. I try to use JavaScript but i should think about a function and I don't found any of it to apply at type table. Thinking about CSS still also hard since I cannot find a relation between the table and the button.

  • Button top increase with multiple lines

    - by NeTeInStEiN
    Some very very strange behaviour was appearing in my Android application. I was extending Button to replace the standard. In my own button I set: - TextAppearence (text 16px, bold..) - BackgroundDrawable (to an selector that replaced the standard button, that used images of 60px) - Gravity: LEFT|CENTER_VERTICAL. Whenever the text was enough to make the button have 2 text lines, if it had the property Gravity.CENTER_VERTICAL, a top padding would appear! This kept me overflowing and googling for weeks... (set paddingTop, singleLine, and other simple solutions didn't work of course!) Finally got the solution!!! @Override protected boolean setFrame(int l, int t, int r, int b) { int fixedTopSize = 5; return super.setFrame(l,fixedTopSize, r, b-t); } By overriding this method on the extended Button finally i got it to work without the irritating top padding... still i don't understand why this happens. Any ideia?

  • Change the background image of a Button when pressed using VisualStateManager

  • JAXB: @XmlTransient on third-party or external super class

    - by Phil
    Hi, I need some help regarding the following issue with JAXB 2.1. Sample: I've created a SpecialPerson class that extends a abstract class Person. Now I want to transform my object structure into a XML schema using JAXB. Thereby I don't want the Person XML type to appear in my XML schema to keep the schema simple. Instead I want the fields of the Person class to appear in the SpecialPerson XML type. Normally I would add the annotation @XmlTransient on class level into the Person code. The problem is that Person is a third-party class and I have no possibility to add @XmlTransient here. How can I tell JAXB that it should ignore the Person class without annotating the class. Is it possible to configure this externally somehow? Have you had the same problem before? Any ideas what the best solution for this problem would be?

  • add methods in subclasses within the super class constructor

    - by deamon
    I want to add methods (more specifically: method aliases) automatically to Python subclasses. If the subclass defines a method named 'get' I want to add a method alias 'GET' to the dictionary of the subclass. To not repeat myself I'd like to define this modifation routine in the base class. But if I check in the base class init method, there is no such method, since it is defined in the subclass. It will become more clear with some source code: class Base: def __init__(self): if hasattr(self, "get"): setattr(self, "GET", self.get) class Sub(Base): def get(): pass print(dir(Sub)) Output: ['__doc__', '__init__', '__module__', 'get'] It should also contain 'GET'. Is there a way to do it within the base class?

  • CSS sliding-door buttons center alignment

    - by rochal
    Hi guys, I need help to align CSS buttons. I tried many different variations and I just cannot center my button the way I want. Firstly, have a look at this url: http://www.front-end-developer.net/cssbuttons/example.htm I'm using 2 images to form a button (this could be done on 1 image, but in this case we've got two). Everything works as expected as long as we apply float:left or float:right to the parent div element, to 'limit' width of the div and close it as soon as the content of the div ends. You can remove float:left from the button to see what I mean. But what about center positioned buttons? I cannot add float:left/right because I want align it in the middle. In theory, I could set { width:XXpx; margin:0 auto; } And I will get what you can see on this picture: But I don't know the length of the text inside. Having different translations my button can be very short, or 5 times that long. I also tried to use <span> instead of <div>, but unfortunately nested inline elements don't respect their padding correctly... And yes, I must use <a> inside, so buttons can be accessed by web crawlers. I'm really stuck on this one.
