  • C# - How to override GetHashCode with Lists in object

    - by Christian
    Hi, I am trying to create a "KeySet" to modify UIElement behaviour. The idea is to create a special function if, eg. the user clicks on an element while holding a. Or ctrl+a. My approach so far, first lets create a container for all possible modifiers. If I would simply allow a single key, it would be no problem. I could use a simple Dictionary, with Dictionary<Keys, Action> _specialActionList If the dictionary is empty, use the default action. If there are entries, check what action to use depending on current pressed keys And if I wasn't greedy, that would be it... Now of course, I want more. I want to allow multiple keys or modifiers. So I created a wrapper class, wich can be used as Key to my dictionary. There is an obvious problem when using a more complex class. Currently two different instances would create two different key, and thereby he would never find my function (see code to understand, really obvious) Now I checked this post: http://stackoverflow.com/questions/638761/c-gethashcode-override-of-object-containing-generic-array which helped a little. But my question is, is my basic design for the class ok. Should I use a hashset to store the modifier and normal keyboardkeys (instead of Lists). And If so, how would the GetHashCode function look like? I know, its a lot of code to write (boring hash functions), some tips would be sufficient to get me started. Will post tryouts here... And here comes the code so far, the Test obviously fails... public class KeyModifierSet { private readonly List<Key> _keys = new List<Key>(); private readonly List<ModifierKeys> _modifierKeys = new List<ModifierKeys>(); private static readonly Dictionary<KeyModifierSet, Action> _testDict = new Dictionary<KeyModifierSet, Action>(); public static void Test() { _testDict.Add(new KeyModifierSet(Key.A), () => Debug.WriteLine("nothing")); if (!_testDict.ContainsKey(new KeyModifierSet(Key.A))) throw new Exception("Not done yet, help :-)"); } public KeyModifierSet(IEnumerable<Key> keys, IEnumerable<ModifierKeys> modifierKeys) { foreach (var key in keys) _keys.Add(key); foreach (var key in modifierKeys) _modifierKeys.Add(key); } public KeyModifierSet(Key key, ModifierKeys modifierKey) { _keys.Add(key); _modifierKeys.Add(modifierKey); } public KeyModifierSet(Key key) { _keys.Add(key); } }

  • Creating a variable list Pashua, OS X & Bash.

    - by S1syphus
    First of all, for those that don't know pashua is a tool for creating native Aqua dialog windows. An example of what a window config looks like is # pashua_run() # Define what the dialog should be like # Take a look at Pashua's Readme file for more info on the syntax conf=" # Set transparency: 0 is transparent, 1 is opaque *.transparency=0.95 # Set window title *.title = Introducing Pashua # Introductory text tb.type = text tb.default = "HELLO WORLD" tb.height = 276 tb.width = 310 tb.x = 340 tb.y = 44 if [ -e "$icon" ] then # Display Pashua's icon conf="$conf img.type = image img.x = 530 img.y = 255 img.path = $icon" fi if [ -e "$bgimg" ] then # Display background image conf="$conf bg.type = image bg.x = 30 bg.y = 2 bg.path = $bgimg" fi pashua_run "$conf" echo " tb = $tb" The problem is, Pashua can't really get output from stdout, but it can get arguments. Following on from what Dennis Williamson posted here. What ideally it should do is generate an output file based on information from a text file, To executed in pashua_run ore add the pashua_run around the window argument: count=1 while read -r i do echo "AB${count}.type = openbrowser" echo "AB${count}.label = Choose a master playlist file" echo "AB${count}.width=310" echo "AB${count}.tooltip = Blabla filesystem browser" echo "some text with a line from the file: $i" (( count++ )) done < TEST.txt >> long.txt SO the output is AB1.type = openbrowser AB1.label = Choose a master playlist file AB1.width=310 AB1.tooltip = Blabla filesystem browser some text with a line from the file: foo AB2.type = openbrowser AB2.label = Choose a master playlist file AB2.width=310 AB2.tooltip = Blabla filesystem browser some text with a line from the file: bar AB3.type = openbrowser AB3.label = Choose a master playlist file AB3.width=310 AB3.tooltip = Blabla filesystem browser some text with a line from the file: dev AB4.type = openbrowser AB4.label = Choose a master playlist file AB4.width=310 AB4.tooltip = Blabla filesystem random So if there is a clever way to get the output of that and place it into pashua run would be cool, on the fly: I.E load te contents of TEST.txt and generate the place it into pashua_run, I've tried using cat and opening the file... but because it's in Pashua_run it doesn't work, is there a smart way to break out then back in? Or the second way which I was thinking, was create get the output then append it into the middle text file containing the pashua runtime, then execute it, maybe slightly hacky, but I would imagine it will do the job. Any ideas? ++ I know I probably could make my life a lot easier, by doing this in actionscript and cocoa, although at present don't have time for such a learning curve, although I do plan to get round to it.

  • open layers LineString not working

    - by AlexS
    Sorry to bother you guys, but I'm stuck with his problem for half a day. I want to draw poly line in OpenLayers using LineString object, so I've copied the example from documentation. It runs ok but i can't see the line on the screen Code looks like this <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> var map; var lineLayer ; var points; var style; var polygonFeature function test() { lineLayer = new OpenLayers.Layer.Vector("Line Layer"); style = { strokeColor: '#0000ff', strokeOpacity: 1, strokeWidth: 10 }; map.addLayer(lineLayer); points = new Array(); points[0] =new OpenLayers.LonLat(-2.460181,27.333984 ).transform(new OpenLayers.Projection("EPSG:4326"), map.getProjectionObject());; points[1] = new OpenLayers.LonLat(-3.864255,-22.5 ).transform(new OpenLayers.Projection("EPSG:4326"), map.getProjectionObject());; var linear_ring = new OpenLayers.Geometry.LinearRing(points); polygonFeature = new OpenLayers.Feature.Vector( new OpenLayers.Geometry.Polygon([linear_ring]), null, style); lineLayer.addFeatures([polygonFeature]); alert("1"); } function initialize() { map = new OpenLayers.Map ("map_canvas", { controls:[ new OpenLayers.Control.Navigation(), new OpenLayers.Control.PanZoomBar(), new OpenLayers.Control.LayerSwitcher(), new OpenLayers.Control.Attribution()], maxExtent: new OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34), maxResolution: 156543.0399, numZoomLevels: 19, units: 'm', projection: new OpenLayers.Projection("EPSG:900913"), displayProjection: new OpenLayers.Projection("EPSG:4326") }); // Define the map layer // Here we use a predefined layer that will be kept up to date with URL changes layerMapnik = new OpenLayers.Layer.OSM.Mapnik("Mapnik"); map.addLayer(layerMapnik); var lonLat = new OpenLayers.LonLat(0, 0).transform(new OpenLayers.Projection("EPSG:4326"), map.getProjectionObject()); map.zoomTo(3); map.setCenter(lonLat, 19); test(); } </head> <body onload="initialize()" > <div id="map_canvas" style="width: 828px; height: 698px"></div> I'm sure I'm missing some parameter in creation of map or something but I really can't figure which one.

  • Why is Magento so slow?

    - by mr-euro
    Is Magento usually so terrible slow? This is my first experience with it and the admin panel simply takes ages to load and save changes. It is a default installation with the test data. The server it is hosted on serves other non-Magento sites super fast. What is it about the PHP code that Magento uses that makes it so slow, and what can be done to fix it?

  • scala integer weirdness

    Suppose you inadvertently use Integer instead of Int, as in this code: import scala.collection.mutable.Map val contributors = Map[String,Integer]() val count = contributors.getOrElseUpdate("john",0) contributors.put("john",count+1) println(contributors) Compiler output: (fragment of test.scala):7: error: type mismatch; found : Int(1) required: String contributors.put("john",count+1) ^ Why "required: String"?

  • What call from the Android Development Tools API should I use to poll project target loading?

    - by Ricardo Gladwell
    I'm writing my own eclipse plug-in that integrates with the Eclipse Android Development Tools (ADT). However, I'm getting a CoreException ("Project target not loaded yet.") thrown when I attempt to call IProject.build on an Android project as part of a unit test: IProject project = importProject(...); project.build(IncrementalProjectBuilder.FULL_BUILD, monitor); Should I be waiting for the project target to load before calling the above? If so, what call should I use to poll the project target loading status?

  • How to delegate SwingWorker's publish to other methods

    - by Savvas Dalkitsis
    My "problem" can be described by the following. Assume we have an intensive process that we want to have running in the background and have it update a Swing JProgress bar. The solution is easy: import java.util.List; import javax.swing.JOptionPane; import javax.swing.JProgressBar; import javax.swing.SwingWorker; /** * @author Savvas Dalkitsis */ public class Test { public static void main(String[] args) { final JProgressBar progressBar = new JProgressBar(0,99); SwingWorker<Void, Integer> w = new SwingWorker<Void, Integer>(){ @Override protected void process(List<Integer> chunks) { progressBar.setValue(chunks.get(chunks.size()-1)); } @Override protected Void doInBackground() throws Exception { for (int i=0;i<100;i++) { publish(i); Thread.sleep(300); } return null; } }; w.execute(); JOptionPane.showOptionDialog(null, new Object[] { "Process", progressBar }, "Process", JOptionPane.OK_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, null, null); } } Now assume that i have various methods that take a long time. For instance we have a method that downloads a file from a server. Or another that uploads to a server. Or anything really. What is the proper way of delegating the publish method to those methods so that they can update the GUI appropriately? What i have found so far is this (assume that the method "aMethod" resides in some other package for instance): import java.awt.event.ActionEvent; import java.util.List; import javax.swing.AbstractAction; import javax.swing.Action; import javax.swing.JOptionPane; import javax.swing.JProgressBar; import javax.swing.SwingWorker; /** * @author Savvas Dalkitsis */ public class Test { public static void main(String[] args) { final JProgressBar progressBar = new JProgressBar(0,99); SwingWorker<Void, Integer> w = new SwingWorker<Void, Integer>(){ @Override protected void process(List<Integer> chunks) { progressBar.setValue(chunks.get(chunks.size()-1)); } @SuppressWarnings("serial") @Override protected Void doInBackground() throws Exception { aMethod(new AbstractAction() { @Override public void actionPerformed(ActionEvent e) { publish((Integer)getValue("progress")); } }); return null; } }; w.execute(); JOptionPane.showOptionDialog(null, new Object[] { "Process", progressBar }, "Process", JOptionPane.OK_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, null, null); } public static void aMethod (Action action) { for (int i=0;i<100;i++) { action.putValue("progress", i); action.actionPerformed(null); try { Thread.sleep(300); } catch (InterruptedException e) { e.printStackTrace(); } } } } It works but i know it lacks something. Any thoughts?

  • Error while creating tests in Visual Studio

    When I try to generate a unit test for the following method (in a public static class) private static string[] GetFields(string line, char sep) { char[] totrim = { '"', ' ' }; return line.Split(sep).Select(col => col.Trim(totrim)).ToArray(); } The Tests output says: While trying to generate your tests, the following errors occurred: This method or property cannot be called within an event handler. It works if I make the function public - I've tried running Publicize.exe manually, it doesn't complain, but doesn't make any difference either.
