  • add JButton into frame with JTable

    - by Edan
    hello, I would like to know how to put a button inside a frame that contain JTable inside. (The button should not be inside a cell, but after the table ends) Here is the example code I wrote so far: class SimpleTableExample extends JFrame { // Instance attributes used in this example private JPanel topPanel; private JTable table; private JScrollPane scrollPane; private JButton update_Button; // Constructor of main frame public SimpleTableExample() { // Set the frame characteristics setTitle("Add new item" ); setSize(300, 200); setBackground( Color.gray ); // Create a panel to hold all other components topPanel = new JPanel(); topPanel.setLayout( new BorderLayout() ); getContentPane().add( topPanel ); // Create columns names String columnNames[] = {"Item Description", "Item Type", "Item Price"}; // Create some data String dataValues[][] = {{ "0", "Entree", "0" }}; // Create a new table instance table = new JTable( dataValues, columnNames ); //////////////////////////// JComboBox item_Type_Combobox = new JComboBox(); item_Type_Combobox = new JComboBox(item_Type.values()); TableColumn column = table.getColumnModel().getColumn(1); column.setCellEditor(new DefaultCellEditor(item_Type_Combobox)); //////////////////////////// // Add the table to a scrolling pane scrollPane = new JScrollPane( table ); topPanel.add( scrollPane, BorderLayout.CENTER ); } } How do I add button after the table I created? thanks in advance

  • Custom WPF TreeView

    - by Robert
    I have a custom class that I would like to bind a WPF TreeView that has three tiers. Each tier needs to be bound like this: Monitor --> LCD --> Samsung 1445 LCD --> CRT --> Sony 125 CRT Here is the example code: public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); SystemInventory sysInventory = new SystemInventory(); //Possibly do something like this. _myTreeView.DataContext = sysInventory.DeviceGroupInstances; } public class SystemInventory { public ObservableCollection<DeviceGroup> DeviceGroupInstances { get; set; } public SystemInventory() { DeviceGroupInstances = new ObservableCollection<DeviceGroup>(); DeviceGroupInstances.Add(new DeviceGroup("Monitor")); } } public class DeviceGroup { public string DeviceGroupName { get; set; } public ObservableCollection<DeviceType> DeviceTypeInstances { get; set; } public DeviceGroup(string deviceGroupName) { DeviceTypeInstances = new ObservableCollection<DeviceType>(); DeviceGroupName = deviceGroupName; if (deviceGroupName == "Monitor") { DeviceTypeInstances.Add(new DeviceType("LCD")); DeviceTypeInstances.Add(new DeviceType("CRT")); } } } public class DeviceType { public string DeviceTypeName { get; set; } public ObservableCollection<DeviceInstance> DeviceInstances { get; set; } public DeviceType(string deviceGroupName) { DeviceInstances = new ObservableCollection<DeviceInstance>(); DeviceTypeName = deviceGroupName; if (deviceGroupName == "Monitor") { DeviceInstances.Add(new DeviceInstance("Samsung 1445 LCD")); } else { DeviceInstances.Add(new DeviceInstance("Sony 125 CRT")); } } } public class DeviceInstance { public string DeviceInstanceName { get; set; } public DeviceInstance(string instanceName) { DeviceInstanceName = instanceName; } } }

  • Lua Operator Overloading

    - by Pessimist
    I've found some places on the web saying that operators in Lua are overloadable but I can't seem to find any example. Can someone provide an example of, say, overloading the + operator to work like the .. operator works for string concatenation? EDIT 1: to Alexander Gladysh and RBerteig: If operator overloading only works when both operands are the same type and changing this behavior wouldn't be easy, then how come the following code works? (I don't mean any offense, I just started learning this language): printf = function(fmt, ...) io.write(string.format(fmt, ...)) end Set = {} Set.mt = {} -- metatable for sets function Set.new (t) local set = {} setmetatable(set, Set.mt) for _, l in ipairs(t) do set[l] = true end return set end function Set.union (a,b) -- THIS IS THE PART THAT MANAGES OPERATOR OVERLOADING WITH OPERANDS OF DIFFERENT TYPES -- if user built new set using: new_set = some_set + some_number if type(a) == "table" and type(b) == "number" then print("building set...") local mixedset = Set.new{} for k in pairs(a) do mixedset[k] = true end mixedset[b] = true return mixedset -- elseif user built new set using: new_set = some_number + some_set elseif type(b) == "table" and type(a) == "number" then print("building set...") local mixedset = Set.new{} for k in pairs(b) do mixedset[k] = true end mixedset[a] = true return mixedset end if getmetatable(a) ~= Set.mt or getmetatable(b) ~= Set.mt then error("attempt to 'add' a set with a non-set value that is also not a number", 2) end local res = Set.new{} for k in pairs(a) do res[k] = true end for k in pairs(b) do res[k] = true end return res end function Set.tostring (set) local s = "{" local sep = "" for e in pairs(set) do s = s .. sep .. e sep = ", " end return s .. "}" end function Set.print (s) print(Set.tostring(s)) end s1 = Set.new{10, 20, 30, 50} s2 = Set.new{30, 1} Set.mt.__add = Set.union -- now try to make a new set by unioning a set plus a number: s3 = s1 + 8 Set.print(s3) --> {1, 10, 20, 30, 50}

  • How to create an XML document from a .NET object?

    - by JL
    I have the following variable that accepts a file name: var xtr = new XmlTextReader(xmlFileName) { WhitespaceHandling = WhitespaceHandling.None }; var xd = new XmlDocument(); xd.Load(xtr); I would like to change it so that I can pass in an object. I don't want to have to serialize the object to file first. Is this possible? Update: My original intentions were to take an xml document, merge some xslt (stored in a file), then output and return html... like this: public string TransformXml(string xmlFileName, string xslFileName) { var xtr = new XmlTextReader(xmlFileName) { WhitespaceHandling = WhitespaceHandling.None }; var xd = new XmlDocument(); xd.Load(xtr); var xslt = new System.Xml.Xsl.XslCompiledTransform(); xslt.Load(xslFileName); var stm = new MemoryStream(); xslt.Transform(xd, null, stm); stm.Position = 1; var sr = new StreamReader(stm); xtr.Close(); return sr.ReadToEnd(); } In the above code I am reading in the xml from a file. Now what I would like to do is just work with the object, before it was serialized to the file. So let me illustrate my problem using code public string TransformXMLFromObject(myObjType myobj , string xsltFileName) { // Notice the xslt stays the same. // Its in these next few lines that I can't figure out how to load the xml document (xd) from an object, and not from a file.... var xtr = new XmlTextReader(xmlFileName) { WhitespaceHandling = WhitespaceHandling.None }; var xd = new XmlDocument(); xd.Load(xtr); }

  • Please critisize this method

    - by Jakob
    Hi I've been looking around the net for some tab button close functionality, but all those solutions had some complicated eventhandler, and i wanted to try and keep it simple, but I might have broken good code ethics doing so, so please review this method and tell me what is wrong. public void AddCloseItem(string header, object content){ //Create tabitem with header and content StackPanel headerPanel = new StackPanel() { Orientation = Orientation.Horizontal, Height = 14}; headerPanel.Children.Add(new TextBlock() { Text = header }); Button closeBtn = new Button() { Content = new Image() { Source = new BitmapImage(new Uri("images/cross.png", UriKind.Relative)) }, Margin = new Thickness() { Left = 10 } }; headerPanel.Children.Add(closeBtn); TabItem newTabItem = new TabItem() { Header = headerPanel, Content = content }; //Add close button functionality closeBtn.Tag = newTabItem; closeBtn.Click += new RoutedEventHandler(closeBtn_Click); //Add item to list this.Add(newTabItem); } void closeBtn_Click(object sender, RoutedEventArgs e) { this.Remove((TabItem)((Button)sender).Tag); } So what I'm doing is storing the tabitem in the btn.Tag property, and then when the button is clicked i just remove the tabitem from my observablecollection, and the UI is updated appropriately. Am I using too much memory saving the tabitem to the Tag property?

  • Trying to Use LoadMoreElement in Monotouch.Dialog

    - by user1487581
    I am using Monotouch to write an Ipad app. The app uses tables to browse down through a directory tree and then select a file. I have used Monotouch.Dialog to browse the directories and I set up the directory tables as the app starts.However there are too many files to set up in a table as the app starts and so I want to set up the 'file table' as the file is selected from the lowest level directory table. I am trying to use LoadMoreElement to do this but I cannot make it work or find any examples online. I have coded the 'Elements API Walkthrough' in the Xamarin tutorial at:- http://docs.xamarin.com/ios/tutorials/MonoTouch.Dialog I then add a new section to the code:- _addButton.Clicked += (sender, e) => { ++n; var task = new Task{Name = "task " + n, DueDate = DateTime.Now}; var taskElement = new RootElement (task.Name){ new Section () { new EntryElement (task.Name, "Enter task description", task.Description) }, new Section () { new DateElement ("Due Date", task.DueDate) }, new Section() { new LoadMoreElement("Passive","Active", delegate {MyAction();}) } }; _rootElement [0].Add (taskElement); Where MyAction is:- public void MyAction() { Console.WriteLine ("we have been actioned"); } The problem is that MyAction is triggered and Console.Writeline writes the message but the table stays in the active state and never returns to passive. the documentation says:- Once your code in the NSAction is finished, the UIActivity indicator stops animating and the normal caption is displayed again. What am I missing? Ian

  • Using Custom MapType with Google Maps API

    - by Pat Long - Munkii Yebee
    I realise there are a couple of examples such as Maoki's Add Your Own Custom Map and Mike Williams' [link text][Google Maps API Tutorial] however I have looked at these and still end up with a Grey box. The API will not call my "getTileUrl" callback function. This is the javascript I am using var map = new GMap2(document.getElementById("map")); map.setUIToDefault(); var copyCollection = new GCopyrightCollection('Map Data:'); var copyright = new GCopyright(1, new GLatLngBounds(new GLatLng(-90, -180), new GLatLng(90, 180)), 0, "©2006 RunwayFinder.com"); copyCollection.addCopyright(copyright); var tilelayers = [new GTileLayer(copyCollection, 3, 11)]; tilelayers[0].getTileUrl = function (a, b) { var z = 17 - b; var f = "http://localhost:25213/test.jpg?x=" + a.x + "&y=" + a.y + "&zoom=" + z + "&width=100&height=100"; return f; }; var custommap = new GMapType(tilelayers, new GMercatorProjection(12), "Chart", { errorMessage: "No chart data available" }); map.addMapType(custommap); Can anyone see what it is i am doing wrong?

  • How can I control the width of JTextFields in Java Swing?

    - by Jonas
    I am trying to have several JTextFields on a single row, but I don't want them to have the same width. How can I control the width and make some of them wider than others? I want that they together take up 100% of the total width, so it would be good if I could use some kind of weigthing. I have tried with .setColumns() but it doesn't make sense. Here is my code: class Row extends JComponent { public Row() { this.setLayout(new BoxLayout(this, BoxLayout.X_AXIS)); JTextField fld1 = new JTextField("First field"); JTextField fld2 = new JTextField("Second field, should be longer"); JTextField fld3 = new JTextField("Short field"); JTextField fld4 = new JTextField("Another field"); fld1.setBorder(null); fld2.setBorder(null); fld3.setBorder(null); fld4.setBorder(null); fld1.setFocusable(false); fld2.setFocusable(false); fld3.setFocusable(false); fld4.setFocusable(false); fld1.setColumns(5); // makes no sense this.add(fld1); this.add(fld2); this.add(fld3); this.add(fld4); } } this.setLayout(new GridLayout(20,0)); this.add(new Row()); this.add(new Row()); this.add(new Row());

  • Trouble adding video controls to video selected by XML comboBox

    - by user560128
    Hello, it's been a few years since I've touched flash, so perhaps I'm just overlooking something. If anyone could look at the code and offer any suggestions that would be awesome. What's working, I select a video from a combobox that is populated from an XML file, pick the video and it plays. I've been trying to add pause/play, stop, forward and reverse functionality, once I get that to work I also want to add a video scrubber(slider), and previous/next buttons to go to the previous/next video as listed in the xml file. At the moment I have a component button on the stage called playButton, which I'm trying to use for pause/play functionality. Below is my code, the player control is at the very bottom. Thanks. import fl.data.DataProvider; var nc:NetConnection = new NetConnection(); nc.connect(null); var ns:NetStream = new NetStream(nc); var videosXML:XML = new XML(); var loader:URLLoader = new URLLoader(); var request:URLRequest= new URLRequest("xml/videos.xml"); var videos:Array = new Array({label:"Select a Video",data:""}); var client:Object = new Object(); theVideo.attachNetStream(ns); ns.client = client; loader.addEventListener(Event.COMPLETE,loaderOnComplete); loader.load (request); function loaderOnComplete(event:Event):void{ videosXML = new XML(event.target.data); for each (var video:XML in videosXML.video){ videos.push({label:video.name.toString(),data:video.url.toString()}); } moviesCB.dataProvider = new DataProvider(videos); } moviesCB.addEventListener(Event.CHANGE, changeHandler); function changeHandler(event:Event):void { if(ComboBox(event.target).selectedItem.data != ""){ ns.play(ComboBox(event.target).selectedItem.data); } }; client.onMetaData = metadataHandler; function metadataHandler(md:Object):void{ } //player controls playButton.onRelease = function() { ns.pause(); }

  • SWT: scrollable area within a tab

    - by DaveJohnston
    I am trying to add a scrollable area to my tabbed window. So far I have a CTabFolder in a shell. I have added 5 CTabItems to it and everything works as expected. On one of my CTabItems the contents are too big to fit on the screen so I would like to be able to scroll. The contents is a collection of Groups each containing various widgets. So the CTabFolder is created as follows: CTabFolder tabs = new CTabFolder(shell, SWT.BORDER); tabs.setSimple(false); tabs.setUnselectedImageVisible(false); tabs.setUnselectedCloseVisible(false); tabs.setMinimizeVisible(false); tabs.setMaximizeVisible(false); FormData tabsLayoutData = new FormData(); tabsLayoutData.top = new FormAttachment(0, 5); tabsLayoutData.left = new FormAttachment(0, 5); tabsLayoutData.bottom = new FormAttachment(92, 0); tabsLayoutData.right = new FormAttachment(100, -5); tabs.setLayoutData(tabsLayoutData); Then the CTabItem: CTabItem tab = new CTabItem(tabs, SWT.NONE); tab.setText("Role"); Then the contents: Composite tabArea = new Composite(tabs, SWT.V_SCROLL); tabArea.setLayout(new FormLayout()); tab.setControl(tabArea); So the groups contained within the tab are created with tabArea as the parent and everything appears as you would expect. The problem is though that the vertical scroll bar is always present but doesn't seem to do anything. The contents are chopped off at the bottom of the tabArea composite. Is there anything else I need to do to get the scrolling to work properly?

  • Please critique this method

    - by Jakob
    Hi I've been looking around the net for some tab button close functionality, but all those solutions had some complicated eventhandler, and i wanted to try and keep it simple, but I might have broken good code ethics doing so, so please review this method and tell me what is wrong. public void AddCloseItem(string header, object content){ //Create tabitem with header and content StackPanel headerPanel = new StackPanel() { Orientation = Orientation.Horizontal, Height = 14}; headerPanel.Children.Add(new TextBlock() { Text = header }); Button closeBtn = new Button() { Content = new Image() { Source = new BitmapImage(new Uri("images/cross.png", UriKind.Relative)) }, Margin = new Thickness() { Left = 10 } }; headerPanel.Children.Add(closeBtn); TabItem newTabItem = new TabItem() { Header = headerPanel, Content = content }; //Add close button functionality closeBtn.Tag = newTabItem; closeBtn.Click += new RoutedEventHandler(closeBtn_Click); //Add item to list this.Add(newTabItem); } void closeBtn_Click(object sender, RoutedEventArgs e) { this.Remove((TabItem)((Button)sender).Tag); } So what I'm doing is storing the tabitem in the btn.Tag property, and then when the button is clicked i just remove the tabitem from my observablecollection, and the UI is updated appropriately. Am I using too much memory saving the tabitem to the Tag property?

  • ambient values in mvc2.net routing

    - by Muhammad Adeel Zahid
    Hello Everyone, i have following two routes registered in my global.asax file routes.MapRoute( "strict", "{controller}.mvc/{docid}/{action}/{id}", new { action = "Index", id = "", docid = "" }, new { docid = @"\d+"} ); routes.MapRoute( "default", "{controller}.mvc/{action}/{id}", new { action = "Index", id = "" }, new { docConstraint = new DocumentConstraint() } ); and i have a static "dashboard" link in my tabstrip and some other links that are constructed from values in db here is the code <ul id="globalnav" class = "t-reset t-tabstrip-items"> <li class="bar" id = "dashboard"> <%=Html.ActionLink("dash.board", "Index", pck.Controller, new{docid =string.Empty,id = pck.PkgID }, new { @class = "here" })%> </li> <% foreach (var md in pck.sysModules) { %> <li class="<%=liClass%>"> <%=Html.ActionLink(md.ModuleName, md.ActionName, pck.Controller, new { docid = md.DocumentID}, new { @class = cls })%> </li> <% } %> </ul> Now my launching address is localhost/oa.mvc/index/11 clearly matching the 2nd route. but when i visit any page that has mapped to first route and then come back to dash.board link it shows me localhost/oa.mvc/7/index/11 where 7 is docid and picked from previous Url. now i understand that my action method is after docid and changing it would not clear the docid. my question here is that can i remove docid in this scenario without changing the route. regards adeel

  • "pushModalScreen called by a non-event thread" thrown on event thread

    - by JGWeissman
    I am trying to get my Blackberry application to display a custom modal dialog, and have the opening thread wait until the user closes the dialog screen. final Screen dialog = new FullScreen(); ...// Fields are added to dialog Application.getApplication().invokeAndWait(new Runnable() { public void run() { Application.getUiApplication().pushModalScreen(dialog); } }); This is throwing an Exception which says "pushModalScreen called by a non-event thread" despite the fact that I am using invokeAndWait to call pushModalScreen from the event thread. Any ideas about what the real problem is? Here is the code to duplicate this problem: package com.test; import net.rim.device.api.ui.*; import net.rim.device.api.ui.component.*; import net.rim.device.api.ui.container.*; public class Application extends UiApplication { public static void main(String[] args) { new Application(); } private Application() { new Thread() { public void run() { Application.this.enterEventDispatcher(); } }.start(); final Screen dialog = new FullScreen(); final ButtonField closeButton = new ButtonField("Close Dialog"); closeButton.setChangeListener(new FieldChangeListener() { public void fieldChanged(Field field, int context) { Application.getUiApplication().popScreen(dialog); } }); dialog.add(closeButton); Application.getApplication().invokeAndWait(new Runnable() { public void run() { try { Application.getUiApplication().pushModalScreen(dialog); } catch (Exception e) { // To see the Exception in the debugger throw new RuntimeException(e.getMessage()); } } }); System.exit(0); } } I am using Component Package version 4.5.0.

  • Problem with setVisible (true)

    - by Jessy
    The two examples shown below are same. Both are supposed to produce same result e.g. generate the coordinates of images displayed on JPanel. Example 1, works perfectly (print the coordinates of images), however example 2 returning 0 for the coordinate. I was wondering why because, I have put the setvisible (true) after adding the panel, in both examples. The only difference is that example 1 used extends JPanel and example 2 extends JFrame EXAMPLE 1: public class Grid extends JPanel{ public static void main(String[] args){ JFrame jf=new JFrame(); jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); final Grid grid = new Grid(); jf.add(grid); jf.pack(); Component[] components = grid.getComponents(); for (Component component : components) { System.out.println("Coordinate: "+ component.getBounds()); } jf.setVisible(true); } } EXAMPLE 2: public class Grid extends JFrame { public Grid () { setLayout(new GridBagLayout()); GridBagLayout m = new GridBagLayout(); Container c = getContentPane(); c.setLayout (m); GridBagConstraints con = new GridBagConstraints(); //construct the JPanel pDraw = new JPanel(); ... m.setConstraints(pDraw, con); pDraw.add (new GetCoordinate ()); // call new class to generate the coordinate c.add(pDraw); pack(); setVisible(true); } public static void main(String[] args) { new Grid(); } }

    - by Edan
    Hello, I have a class containing Enum with values. (names) In other class I would like to enter inside a table a cell type of JCombobox that will use these enums values. my problem is to combain between string values and the enum. for example the enum class: enum item_Type {entree, main_Meal, Dessert, Drink} for example the table class: setTitle("Add new item" ); setSize(300, 80); setBackground( Color.gray ); // Create a panel to hold all other components topPanel = new JPanel(); topPanel.setLayout( new BorderLayout() ); getContentPane().add( topPanel ); //new JComboBox(item_Type.values()); JComboBox aaa = new JComboBox(); aaa = new JComboBox(item_Type.values()); TableColumn sportColumn = table.getColumnModel().getColumn(2); // Create columns names String columnNames[] = {"Item Description", "Item Type", "Item Price"}; // Create some data String dataValues[][] = {{ "0", aaa, "0" }}; // Create a new table instance table = new JTable( dataValues, columnNames ); // Add the table to a scrolling pane scrollPane = new JScrollPane( table ); topPanel.add( scrollPane, BorderLayout.CENTER ); I know that at the dataValues array I cant use aaa (the enum jcombobox). How can I do that? thanks in advance.

  • C# WinForms MultiThreading in Loop

    - by Goober
    Scenario I have a background worker in my application that runs off and does a bunch of processing. I specifically used this implementation so as to keep my User Interface fluid and prevent it from freezing up. I want to keep the background worker, but inside that thread, spawn off ONLY 3 MORE threads - making them share the processing (currently the worker thread just loops through and processes each asset one-by-one. However I would like to speed this up but using only a limited number of threads. Question Given the code below, how can I get the loop to choose a thread that is free, and then essentially wait if there isn't one free before it continues. CODE foreach (KeyValuePair<int, LiveAsset> kvp in laToHaganise) { Haganise h = new Haganise(kvp.Value, busDate, inputMktSet, outputMktSet, prodType, noOfAssets, bulkSaving); h.DoWork(); } Thoughts I'm guessing that I would have to start off by creating 3 new threads, but my concern is that if I'm instantiating a new Haganise object each time - how can I pass the correct "h" object to the correct thread..... Thread firstThread = new Thread(new ThreadStart(h.DoWork)); Thread secondThread =new Thread(new ThreadStart(h.DoWork)); Thread thirdThread = new Thread(new ThreadStart(h.DoWork)); Help greatly appreciated.

  • How do you manually set a RadioGroup value in wicket?

    - by Kane
    I'm trying to change the selected radio button in a Wicket RadioGroup during an AjaxEventBehavior but can't figure out how to do so. Specifically when a user types some text in a textbox I want to change the selected radio button to one I specify. How do you do this? Here's what I have so far (it crashes on addComponent): myRadioGroup = new RadioGroup("MyNewGroup", new PropertyModel(getPojo(), "selectedGroup")); Radio internalRadio = new Radio("InternalDirectoryNumber", new Model("Internal")); myRadioGroup .add(internalRadio); Radio externalRadio = new Radio("OtherMobileNumber", new Model("External")); myRadioGroup .add(externalRadio); TextField myTxtField= new TextField("TextBoxPrivateNumber", new PropertyModel(getVoiceItem(), "privateMobilePhone")); myTxtField.add( new AjaxEventBehavior( "onKeyUp" ) { @Override protected void onEvent(AjaxRequestTarget target) { Component component = target.getPage().get("myForm:MyNewGroup").setDefaultModelObject("External"); target.addComponent(component); //this causes an exception } }); myRadioGroup .add(myTxtField); Here is the exception that's thrown. java.lang.IllegalArgumentException: cannot update component that does not have setOutputMarkupId property set to true. Component: [MarkupContainer [Component id = myRadioGroup]] What's the proper way to do this? I'm not finding a whole lot of wicket documentation for this online.
