• Remove class when move to next menu item

  - by danit

  I have a simple nav made up of the following HTML; <div class="inner"> <div class="button"><img class="portal" src="images/portalbutton.png" /></div> <a href="#"><div class="prod_description">&nbsp;</div></a> </div> There are a number of items (All set to float left along side each other) to make up a nav bar. When I hover over .button and/or .prod_description I want the .inner <div> to have the class .hover added to it. This is so I can set a background image around the whole thing (Kind of like highlighting the nav item). I only then want to remove .hover when another .button or .prod_description is hovered over, in which case this nav item takes the .hover class.

• Joomla forwarding code to the View...is this the correct way to do it?

  - by jax

  Here are some sample methods from my Controller class. Now when the user clicks the New button $task=add is sent to the Controller and the add() method is called. As you can see it does not really do anything, it just creates a url and forwards it off to the correct view. Is this the correct way of doing things in the MVC pattern? /** * New button was pressed */ function add() { $link = JRoute::_('index.php?option=com_myapp&c=apps&view=editapp&cid[]=', false); $this->setRedirect($link); } /** * Edit button was pressed - just use the first selection for editing */ function edit() { $cid = JRequest::getVar( 'cid', array(0), '', 'array' ); $id = $cid[0]; $link = JRoute::_("index.php?option=com_myapp&c=apps&view=editapp&cid[]=$id", false); $this->setRedirect($link); }

• Ajax twice + facbook login/logout

  - by Devenv

  Hi, I have a very specific problem. The site I'm developing loads the FB connect button by ajax (it loads the box that includes FBC button). And when user logs in it loads instead of it the box with FB logout link. The problem is that FB requires to call FB.init() at the end of the body (when all the FB stuff is already on the page) and you can't do it twice as the second time is ignored. So what happens is - I do FB.init() inside the login box and FBC button works perfectly, but the logout link doesn't as FB.init() doesn't work there. The only solution I came up with is to place the login and logout buttons outside of ajax boxes and show them in the right places after ajax boxes are loaded. I'm pretty much sure this will work but I don't like the solution (which looks more like hack).

• ASP.Net Problem with View Control

  - by tking

  I admit, I'm an .NET n00b. Basically what I'm trying to do is I have a page with a text box on it and an image button. On click of the image button I want it to show a view control I have set up. Inside this view control is an image and some text. So this is what I have in my code-behind. protected void btnSubmit_Click(object sender, ImageClickEventArgs e) { string email = txtUnsubscribe.Text; vwSuccess.Visible = true; } Simple right? Well when I click on the button for submit, I get the "Object reference not set to an instance of an object." error message. Where am I going wrong?

• How to access radioButton individual items?

  - by vikitor

  Hello, I've got 2 radio button groups showed differently depending on the value selected on another radio button. The thing is that I would like to set the default value of the group to the first element in the radiobutton group, but when I change from the other radio button it preserves the value previously selected, when I want it to be reset to the default value. I've been searching in the javascript repository but apparently I cannot access like it says with radio[1].checked = true... It says that radio[1] is undefined, but radio is an HTML Input element object. I'm accessing it from a different file, but var radio = document.getElementById("radio") works, but I can't access the individual radiobuttons. Thank you in advance

• Simple iPhone tally method question

  - by Rob

  Just trying to create a simple method that counts up 1 on the tally when the button is pressed. My knowledge is extremely limited and I am pretty sure that my problem is somewhere in the method implementation: -(IBAction) updateTally:(id) sender { NSString *text; int total = 0; total = total + 1; text=[[NSString alloc] initWithFormat: @"%i", total]; lblTally.text = text; } I have done the necessary interface declarations for the lblTally UILabel and the updateTally method. I suspect that there is some sort of an NSString/int/%i/%@ mixup that I am making but I'm not sure how to fix it. When I run the program as it currently is it displays a 0 in the lblTally label field on the iphone. When I press the button it then displays a 1 in that field. However, if I continue to press the button - nothing happens.

• I can't set main Class variable in onCreate Method

  - by natrollus

  Main class has two variables that want to reach another class: public class MyClassA extends Activity { int i = 1; Button b1; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); this.i = 31; this.b1 = (Button) findViewById(R.id.btn1); ~~ } } Second class want to call variables in mainClass object: public class MyclassB implements OnClickListener{ MyClassA mainClass = new MyClassA(); Button btn = mainClass.b1; int n = mainClass.i; public void OnClick(View arg0){ Log.v("btn:",btn); Log.v("int:",n); } //btn returns null; //int returns 1; But onCreate method not set variables.. Why not set main class variables like this.i=31 ?

• Breaking from for loop in MATLAB GUI

  - by Nick

  I have a for loop in the opening function of a GUI in MATLAB and I'm trying to use a callback button to break the loop. I'm new to MATLAB. Here's the code I have: %In the opening function of the GUI handles.stop_now = 0; for i=1:inf if handles.stop_now==1 break; end end % Executes on button press function pushbutton_Callback(hObject, eventdata, handles) % hObject handle to end_segmenting_button (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) handles.stop_now=1; guidata(hObject, handles); For some reason, despite defining the variables with handles, the loop doesn't break upon pressing the button. Anyone know what's going on? Thanks.

• add gtk.widget in a gnome Applet

  - by dominos

  Hi, I have a question : I write a little gnome applet, and when we click on a button i want to add a gtk.widget under the "gnome-panel" like the calendar of the clock-applet. But I don't know how to do this. It's my code : listButton = gtk.Button(_("lastest")) self.listTwitt = gtk.TreeView() mainLayout = gtk.VBox() mainLayout.pack_start(listButton) mainLayout.pack_start(self.listTwitt) self.applet.add(mainLayout) With this code, when i click on the button, the list shows up in the gnome panel : it's because I add it in the mainLayout. So how do I add it under the "gnome-panel". Thanks

• updating a shape in scene with a for loop using javafx

  - by Susanta

  Following is a code fragment. I am updating a rectangle using a for loop when a button is pressed. This is a model for my ultimate intention of showing visualization of data model as it changes large number of times inside a for loop. It works but I see only one change. Now since I am changing the width randomly I should see large number of changes. It seems I am making a wrong assumption on something basic. The code goes below: 7 var rec: Rectangle = Rectangle { 8 x: 10, y: 10 9 width: 140, height: 90 10 fill: Color.BLACK 11 } 12 13 Stage { 14 title: "MyApp" 15 scene: Scene { 16 width: 200 17 height: 200 18 content: [ 19 rec, 20 Button { 21 text: "Button" 22 action: function () { 23 for (i in [1..999]) { 24 rec.width = 25 + java.lang.Math.random()*50; 25 } 26 } 27 } 28 ] 29 } 30 }

• Two buttons in a form, Both called

  - by coffeeaddict

  Here's my ASP.NET form. When I click one button it calls both jQuery functions. It's probably a rudimentary HTML question but I'm not sure why: <form id="form1" runat="server"> <div id="testDialog"> </div> <p><input type="button" id="invoke1" value="test 1" /></p> <input type="button" id="invoke2" value="test 2" /> </form> <script type="text/javascript"> $(function() { $("input:invoke1").click(function(){ showSomething("testDialog"); }); $("input:invoke2").click(function(){ showSomething2("test.aspx", options); }); }); </script>

• iPhone SDK: How do I programatically change the background image of a UIButton added to a NIB?

  - by user304583

  I've seen several questions/answers related to entirely creating a button in code, but not one which would let me know how to change the button image in code, when I originally added the button to my NIB in Interface Builder. I know how to change the background in Interface Builder.. but I want to change it in code, so I can change it automagically. Any help really appreciated! Perhaps the answer is so obvious nobody needs to ask.. if so please forgive the dweeb that I am and help! :-)

• Automatic VisualState Manager in Silverlight

  - by Matt

  If you create a simple button and then choose Edit Template - Edit a Copy, Blend will automatically generate a style area, along with all the button states (MouseEnter, MouseLeave, Pressed, etc). No where in the code behind or auto generated style area does it say that on a "MouseOver" event, change the state to "MouseOver", but it still manages to work! Is the only way to change a button's state have to be done the code behind using the VisualStateManager.GoToState method, or can you change it much like CSS does (a:hover) using the VisualStateManager? From my experience, setting just doesn't seem to do the trick.

• Add multiple Styles to Silverlight Control

  - by lidermin

  Hello, I'm using silverlight and I defined two styles for the page: ExpanderBottomRightButtonStyle ExpanderScaleStyle Now I want to add those two styles to the same control: <controls:Expander x:Name="expBRButton" Grid.Row="1" Grid.Column="2" Margin="5" Style="{StaticResource ExpanderBottomRightButtonStyle}"> <controls:Expander.Content> <Button Content="&lt;Button&gt;"></Button> </controls:Expander.Content> </controls:Expander> I don't want to join the two styles in one, cause I need them separately too. I thought something like: Style="{StaticResource ExpanderBottomRightButtonStyle ExpanderScaleStyle}" But it's not possible. How should I do this? I'm new on Silverlight 3. Thanks in advance.

• WPF: how to make normal listbox left-drag-select behavior use middle mouse instead?

  - by Scott Bilas

  I'm building a special listbox control that our designers want customized in some tweaky ways. One thing they want to see is that the middle button-drag does what the left button-drag normally does (we are repurposing left-drag to other things). So it needs the two key features that left-drag does in a ListBox default implementation: While holding down the button and dragging, the selection starts where I click down and extends to where I drag. While dragging outside the listbox region, it scrolls if there is scrollable space in that direction. Before I go an duplicate this functionality by hand, is there any easy way to fool ListBox into thinking it's getting left-mouse drag events but instead is getting middle-mouse?

• Allowing pop-up's and downloads with flex

• Pop up window dialogs

  - by Omega

  In Cocoa, my application's main window has a button. How can I make it so when you click it, a new window will be generated and set focus to such window so that the main window can not be clicked or interacted with at all? This new window will have a textfield and a submit button. You click it and the window is supposed to close and send the textfield's data back to the main window (and it will recover focus as well). I found this: How to open a new window on button click in Cocoa Mac Application? But the answer doesn't seem to be working for me. The function showWindow doesn't seem to be recognized...

• Changing the cursor in WPF sometimes works, sometimes doesn't

  - by Scott

  On several of my usercontrols, I change the cursor by using this.Cursor = Cursors.Wait; when I click on something. Now I want to do the same thing on a WPF page on a button click. When I hover over my button, the cursor changes to a hand, but when I click it, it doesn't change to the wait cursor. I wonder if this has something to do with the fact that it's a button, or because this is a page and not a usercontrol? This seems like weird behavior.

• iPhone SKD make the iPod controller appear

  - by nico

  Hi all, It's been a while I'm consulting stackoverflow, but this time I didn't find any answer :( My question is quite simple :) On an iPhone/iPod touch, play music. Double tap the home button while the music is playing. You will see appear a popup with the play/pause/next/previous buttons and a volume control. Do you know if it's possible to make this popup appear programmatically ? I mean, I would like to add a button in my app that will display the popup, avoiding the user to double tap the home button (most of them doesn't know this shortcut). Thank you in advance !
