  • Need Help: adding MouseListeners to JComponents (Drawing a JComponent and then attaching a MouseListener)

    - by user1074574
    Drawing a JComponent and then attaching a MouseListener seems very simple to me, but not in this case: I'm having a problem with a MouseListener attached to a child JComponent; here's some brief code to help describe it: Note: The BGT class has implemented ActionListers/MouseListeners that do not have any code in them, and 'figures' is an array of SwingThings. public class GC extends BGT{ public GC(){ super(); buildJMenu(); drawPanel.addMouseListener(this); //drawPanel being the panel that draws the JComponents (it is a public variable in the BGT class) drawPanel.addMouseMotionListener(this); this.addMouseListener(this); } public static void main(String[] args){ GC a = new GC(); }... public void mouseClicked(MouseEvent e) { System.out.println(e.getSource()); //This only seems to print out the DrawPanel's information }... public void mouseReleased(MouseEvent e) { repaint(); ... tempMyJTextField = new MyJTextField(startX, startY, width, height); tempMyJTextField.addMouseListener(this); tempMyJTextField.addMouseMotionListener(this); figures.add(tempMyJTextField); for(int i = 0; i < figures.size(); i++) figures.get(i).addTo(drawPanel); } This is the addTo method in the MyJTextField class: public class MyJTextField extends JTextField implements SwingThing{ ... public void addTo(JPanel p) { p.add(myTextField); } ... } In the MouseClicked event it never registers that the JComponent was clicked. (The drawing/painting works fine) Thanks.

  • how to access a different movieclip within the flash in AS3

    - by Pieter888
    I've been trying to learn Action Script 3 the past few weeks, making tiny interactive games to learn the basics. I stumble upon a problem every now and then but most of the times google helps me out. But this problem has got me stuck so please help: The main stage contains two objects(movieclips), the player and a wall. The player has got his own code so when I drag in the player object I don't have to write any code into the main stage to be able to move the player. This all worked pretty well and I now wanted to add the wall so the player actually has something to bounce into. Now here is the problem, I want to check if the player touches the wall, I've done this before but that was when I used the main stage as my coding playground instead of putting the code in movieclips. How can I check if the player hits the wall within the movement code of the player object?

  • Calling child constructor by casting (ChildClass)parentObject; to track revisions

    - by FreshCode
    To track revisions of a Page class, I have a PageRevision class which inherits from Page and adds a revision ID (Guid RevisionID;). If possible, how should I cast an existing Page object to a PageRevision and ensure that the PageRevision constructor is called to create a new revision ID? I could could have a PageRevision(Page page) constructor which generates the Guid and copies all the Page attributes, but I want to automate it, especially if a Page class has many attributes (and I later add one, and forget to modify the copy constructor). Desired use Page page = new Page(123, "Page Title", "Page Body"); // where 123 is page ID PageRevision revision = (PageRevision)page; // now revision.RevisionID should be a new Guid. Page, PageRevision classes: public class Page { public int ID { get; set; } public string Title { get; set; } public string Body { get; set; } } public class PageRevision : Page { public Guid RevisionID { get; set; } public PageRevision() { this.RevisionID = Guid.NewGuid(); } }

  • codeigniter and OOP general question regarding calling functions, and the parent constuctor

    - by thrice801
    Ok so I have some gaps in my understanding of PHP OOP, classes and functions specifically, this whole constructor class deal. I use both Zend and CI but right now Im trying to figure this out in CI as it is less complicated. So all Im trying to do is understand how to call a function from a view page in code igniter. I understand that might go against MVC but Im working with an api and search results not from my database, so basically, I want to define a function in my class that I am able to call in one of my view pages.. and I keep getting "Fatal error: Call to undefined function functionname" error no matter what I try. I thought I just had to declare public function testing() { echo "testing testing 123; } but calling that from the view I get that error. Then I read something about having to go parent::Controller(); in the index of the class where the testing function also resides? But that didnt work either. Anyways, ya, can someone explain what I need to do in order to call the "testing()" function on one of my view pages? and clarification on the constructor class and what exactly parent::Controller() even does, would be much appreciated as well.

  • Nested forms and automatic creation of parent, children

    - by Karen
    Guys, I was wondering if it was possible to create new parent, children in a has many relationship, using rails nested forms. Rails documentation clearly says that this works in a one to one relationship. Not sure if its the same in has many relationship. For example: If params = { :employee => { :name => "Tester", :account_attributes => {:login => 'tester'} } } works as one to one relationship. So Employee.new(params) works fine. New employee, account are created. Supposing I had params = { :employee => { :name => "Tester", :account_attributes => { "0" => {:login => 'tester'}, "1" => {:login => 'tester2'} } } } Employee.new(params) doesnt work. It fails on child validations saying parent cant be blank. Any help is appreciated. Thanks Karen

  • Retrieve parent node from selection (range) in Gecko and Webkit

    - by Jason
    I am trying to add an attribute when using a wysiwyg editor that uses "createLink" command. I thought it would be trivial to get back the node that is created after the browse executes that command. Turns out, I am only able to grab this newly created node in IE. Any ideas? The following code demonstrates the issue (debug logs at bottom show different output in each browser): var getSelectedHTML = function() { if ($.browser.msie) { return this.getRange().htmlText; } else { var elem = this.getRange().cloneContents(); return $("<p/>").append($(elem)).html(); } }; var getSelection = function() { if ($.browser.msie) { return this.editor.selection; } else { return this.iframe[0].contentDocument.defaultView.getSelection(); } }; var getRange = function() { var s = this.getSelection(); return (s.getRangeAt) ? s.getRangeAt(0) : s.createRange(); }; var getSelectedNode = function() { var range = this.getRange(); var parent = range.commonAncestorContainer ? range.commonAncestorContainer : range.parentElement ? range.parentElement(): range.item(0); return parent; }; // **** INSIDE SOME EVENT HANDLER **** if ($.browser.msie) { this.ec("createLink", true); } else { this.ec("createLink", false, prompt("Link URL:", "http://")); } var linkNode = $(this.getSelectedNode()); linkNode.attr("rel", "external"); $.log(linkNode.get(0).tagName); // Gecko: "body" // IE: "a" // Webkit: "undefined" $.log(this.getSelectedHTML()); // Gecko: "<a href="http://site.com">foo</a>" // IE: "<A href="http://site.com" rel=external>foo</A>" // Webkit: "foo" $.log(this.getSelection()); // Gecko: "foo" // IE: [object Selection] // Webkit: "foo" Thanks for any help on this, I've scoured related questions on SO with no success!

  • Read Parent nodes only from XML using LINQToXML

    - by ItsMeSri
    I have XML string that has parent nodes "Committee" and inside that another child node "Committee" is there. When I am using "from committee in xDocument.DescendantsAndSelf("Committee")" it is reading childnode also, but I don't want to read child nodes, I just want to read Parent nodes only. <Committee> <Position>STAFF</Position> <Appointment>1/16/2006</Appointment> <Committee>PPMSSTAFF</Committee> <CommitteeName>PPMS Staff</CommitteeName> <Expiration>12/25/2099</Expiration> </Committee> <Committee> <Position>STAFF</Position> <Appointment>4/16/2004</Appointment> <Committee>PMOSSTAFF</Committee> <CommitteeName>PPMS </CommitteeName> <Expiration>12/25/2099</Expiration> </Committee> XElement xDocument= XElement.Parse(xml); var committeeXmls = from Committee in xDocument.Descendants("Committee") select new { CommitteeName = Committee.Element("CommitteeName"), Position = Committee.Element("Position"), Appointment = Committee.Element("Appointment"), Expiration = Committee.Element("Expiration") }; int i = 0; foreach (var committeeXml in committeeXmls) { if (committeeXml != null) { drCommittee = dtCommittee.NewRow(); drCommittee["ID"] = ++i; drCommittee["CommitteeName"] = committeeXml.CommitteeName.Value; drCommittee["Position"] = committeeXml.Position.Value; drCommittee["Appointment"] = committeeXml.Appointment.Value; drCommittee["Expiration"] = committeeXml.Expiration.Value; dtCommittee.Rows.Add(drCommittee); // educationXml.GraduationDate.Value, educationXml.Major.Value); } }

  • Treeview does not refresh to show childnode moved from one parent node to another

    - by mike
    I am using the Windows Forms TreeView class which contains a set of TreeNodes. The TreeNodes can have child nodes. I have a root node with 2 sub nodes (Node1 and Node2) Node1 has 2 subnodes (child1 and child2) I have a function that will allow a user to select any node and move it to another node: TreeNode SelectNode = this.TreeView1.SelectedNode; TreeNode DestNode = SelectedNewNode(); //function to select a new node SelectedNode.Remove(); DestNode.Nodes.Add(SelectedNode); this.TreeView1.Refresh(); When this executes, the current selected node (child2) is removed from its current parent (Node1) and added to Node2. However, the Refresh() method of the TreeView control does not show that child2 is under Node2. If I debug it and look at the Nodes collection in the TreeView i do see that child2 is under Node2. Can anyone tell me why the Refresh() method does not redraw the new parent to child mapping? Is there a way to tell the TreeView to redraw with the new mappings?

  • iPhone sdk Cocoa Touch - Pass touches down from parent UIView to child UIScrollview

    - by Joe
    I have a UIView inside my xib in IB and inside that is a UIScrollview that is a small 80x80 square and dynamically loaded with 8 or so 80 x 80 thumbnail images. The UIScrollview is not clipping the images so that they extend out either side so you can swipe left and right to scroll a chosen image into the the centre, paging is on so they snap ti each image. I have researched and found this is the best and possibly only way to do this. The UIScrollview sits in a 'container' UIView for one reason, it is there to receive the touches/swipes and pass them down to it's child the UIScrollview as otherwise all touches would have to start in the small 80x80 UIScrollview area and I wan them to be anywhere along the row of images. I have seen some sample code somewhere for doing this but just can not implement it. Treat me as a noob, starting from beginning to end, how should the UIView and UIScrollview be set up in IB to allow any touches to be passed, and what code should I put into where? The UIView is set up as scroll_container and the child UIScrollview is char_scroll At the moment I have got it all working except for the touches being passed from the parent to the child, and at the moment the touches have to always start inside the UIScrollview (tiny 80x80 box in centre) when I want to be able to swipe left or right in the long 480X80 horizontal parent UIView and have this still scroll the child UIScrollview. Hope you can help and understand what I mean!

  • Ajax call to parent window after form submission

    - by David
    Hi all, Pardon the complicated title. Here's my situation: I'm working on a Grails app, and using jQuery for some of the more complex UI stuff. The way the system is set up, I have an item, which can have various files (user-supplied) associated with it. On my Item/show view, there is a link to add a file. This link pops up a jQuery modal dialog, which displays my file upload form (a remote .gsp). So, the user selects the file and enters a comment, and when the form is submitted, the dialog gets closed, and the list of files on the Item/show view is refreshed. I was initially accomplishing this by adding onclick="javascript:window.parent.$('#myDialog').dialog('close');" to my submit button. This worked fine, but when submitting some larger files, I end up with a race condition where the dialog closes and the file list is refreshed before the new file is saved, and so the list of files is out of date (the file still gets saved properly). So my question is, what is the best way to ensure that the dialog is not closed until after the form submit operation completes? I've tried using the <g:formRemote tag in Grails, and closing the dialog in the "after" attribute (according to the Grails docs, the script is called after form submission), but I receive an error (taken from FireBug) stating that window.parent.$('#myDialog').dialog is not a function Is this a simple JavaScript/Grails syntax issue that I'm missing here, or am I going about this entirely wrong? Thanks so much for your time and assistance!

  • How to get position of parent element - XSL

    - by joe
    What I wish I could do in xsl is the following, but unfortunatly parent/position() is not valid. XSL <xsl:template match="li"> <bullet> <xsl:apply-templates/> </bullet> <!-- todo: if this is the last bullet AND there are no more "p" tags, output footer --> <xsl:if test="count(ancestor::div/*) = parent/position()"> <footer/> </xsl:if> </xsl:template> XML <html> <div> <p>There is an x number of me</p> <p>There is an x number of me</p> <p>There is an x number of me</p> <ul> <li>list item</li> <li>list item</li> <li>list item</li> <li>list item</li> <li>list item</li> </ul> </div> </html> Anyone have any ideas how to figure out this problem from WITHIN my template match for li?

  • MySQL & PHP - Creating Multiple Parent Child Relations

    - by Ashok
    Hi, I'm trying to build a navigation system using categories table with hierarchies. Normally, the table would be defined as follows: id (int) - Primary key name (varchar) - Name of the Category parentid (int) - Parent ID of this Category referenced to same table (Self Join) But the catch is that I require that a category can be child to multiple parent categories.. Just like a Has and Belongs to Many (HABTM) relation. I know that if there are two tables, categories & items, we use a join table categories_items to list the HABTM relations. But here i'm not having two tables but only table but should somehow show HABTM relations to itself. Is this be possible using a single table? If yes, How? If not possible, what rules (table naming, fields) should I follow while creating the additional join table? I'm trying to achieve this using CakePHP, If someone can provide CakePHP solution for this problem, that would be awesome. Even if that's not possible, any solution about creating join table is appreciated. Thanks for your time.

  • Child sProc cannot reference a Local temp table created in parent sProc

    - by John Galt
    On our production SQL2000 instance, we have a database with hundreds of stored procedures, many of which use a technique of creating a #TEMP table "early" on in the code and then various inner stored procedures get EXECUTEd by this parent sProc. In SQL2000, the inner or "child" sProc have no problem INSERTing into #TEMP or SELECTing data from #TEMP. In short, I assume they can all refer to this #TEMP because they use the same connection. In testing with SQL2008, I find 2 manifestations of different behavior. First, at design time, the new "intellisense" feature is complaining in Management Studio EDIT of the child sProc that #TEMP is an "invalid object name". But worse is that at execution time, the invoked parent sProc fails inside the nested child sProc. Someone suggested that the solution is to change to ##TEMP which is apparently a global temporary table which can be referenced from different connections. That seems too drastic a proposal both from the amount of work to chase down all the problem spots as well as possible/probable nasty effects when these sProcs are invoked from web applications (i.e. multiuser issues). Is this indeed a change in behavior in SQL2005 or SQL2008 regarding #TEMP (local temp tables)? We skipped 2005 but I'd like to learn more precisely why this is occuring before I go off and try to hack out the needed fixes. Thanks.

  • Drag/drop problem (draggable in position:relative parent)

    - by MackDaddy
    Here's the scenario, I'm using prototype and scriptaculous, but I believe jquery would have the same issue. I have a list draggable images in a relatively positioned div. The problem is I can't drag the images out of the parent div... well... you can, they're just not visible. If you remove the position:relative on the parent div, it works just fine, I can drag items out of the div perfectly. However because of this little IE7 bug: http://snook.ca/archives/html%5Fand%5Fcss/position%5Frelative%5Foverflow%5Fie/ that position:relative is required. IS there another work around to this bug that does not require setting position? I've tried playing with z-index and everything I can think of to no avail. Here's the CSS for the box: #products{ width: 680px; height: 400px; border: 1px solid gray; /*background-color: #66FF00;*/ overflow-y: scroll; overflow-x: hidden; font-family:"Helvetica Neue","Helvetica"; font-size:12px; font-weight:bold; position: relative; } If you would like to see this bug in action, you can visit it here: http://twinmed-dev.com/template%5Fadd.php. Try searching for an item like "gloves" then adding it to the cart below. Thanks for any help.

  • jQuery slideDown: Parent element doesn't expand?

    - by bobsoap
    Hi, This issue occurs in our beloved Internet Explorer 7: I have a list of items, each with a hidden child div. When user clicks the "expand" button in any list item, the hidden div will expand downwards and push all content beneith it lower. This works just as it should in FF, Chrome, IE8 - but IE7 will not expand the parent element along with its children. This is noticeable because the top-most parent container has an absolutely positioned image at the very bottom (yea... rounded corners) - that doesn't get pushed down when the content expands. I'm guessing that's because of the absolute positioning... Just wondering whether I should attempt to code up some huge workaround in jQuery just for that (assuming I'm able to), or if this is a known issue of some sort. My HTML: <div id="container"> <ul> <li>Click here to expand <div class="hide"></div> </li> <li>Click here to expand <div class="hide"></div> </li> <li>Click here to expand <div class="hide"></div> </li> </ul> <div id="containerbottom"></div> </div> The CSS: #container { position:relative; } #container #containerbottom { position:absolute; bottom:0px; left:0px; } The jQuery is pretty much your everyday slide function: $('ul li').click(function() { $(this).children('.hide').slideDown(200); }); Any ideas?

  • Constraining to parent container with MouseDragElementBehavior

    - by anonymous
    Hi all, I just had a question regarding constraining a control's drag and drop movement to its parent canvas. I tried using the ConstrainToParentBounds property on the MouseDragElementBehavior, however, when this is used the drag must be done really slowly or the movement of the control is choppy or stops altogether. So I am attempting to implement my own boundary constraints. I seem to be running into difficulty though. I am still using the MouseDragElementBehavior but am attempting to supplement it by also handling mouseleftbuttondown, mousemove, mouseleftbuttonup events. I know that these are working (haven't been overridden by the MouseDragElementBehavior) as I have tested them using other methods. I will post my current code below: private void Control_MouseMove(object sender, MouseEventArgs e) { MyControl mc = (MyControl)sender; Canvas canvas = (Canvas)mc.parent; GeneralTransform ct = canvas.TransformToVisual(Application.Current.RootVisual as UIElement; Point canvas_offset = ct.Transform(new Point(0,0)); double canvasTop = canvas_offset.Y; double canvasLeft = canvas_offset.X; GeneralTransform gt = mc.TransformToVisual(Application.Current.RootVisual as UIElement); Point offset = gt.Transform(new Point(0,0)); double controlTop = offset.Y; double controlLeft = offset.X; if(isMouseCaptured) { if(controlTop < canvasTop) { mc.Opacity = 1; //to test if conditions are being met, seems to indicate ok mc.setValue(Canvas.TopProperty, canvasTop); } if(controlLeft < canvasLeft) { mc.Opacity = 1; mc.setValue(Canvas.TopProperty, canvasTop); } } } This is what my code looks like at the moment (I realize there is nothing there for right/bottom). I've tried a bunch of different things at this point and none of them seem to give the desired result; the control's movement is still not constrained to the canvas. Any help/pointers would be greatly appreciated. Thanks!

  • Getting the name of a child class in the parent class (static context)

    - by Benoit Myard
    Hi everybody, I'm building an ORM library with reuse and simplicity in mind; everything goes fine except that I got stuck by a stupid inheritance limitation. Please consider the code below: class BaseModel { /* * Return an instance of a Model from the database. */ static public function get (/* varargs */) { // 1. Notice we want an instance of User $class = get_class(parent); // value: bool(false) $class = get_class(self); // value: bool(false) $class = get_class(); // value: string(9) "BaseModel" $class = __CLASS__; // value: string(9) "BaseModel" // 2. Query the database with id $row = get_row_from_db_as_array(func_get_args()); // 3. Return the filled instance $obj = new $class(); $obj->data = $row; return $obj; } } class User extends BaseModel { protected $table = 'users'; protected $fields = array('id', 'name'); protected $primary_keys = array('id'); } class Section extends BaseModel { // [...] } $my_user = User::get(3); $my_user->name = 'Jean'; $other_user = User::get(24); $other_user->name = 'Paul'; $my_user->save(); $other_user->save(); $my_section = Section::get('apropos'); $my_section->delete(); Obviously, this is not the behavior I was expecting (although the actual behavior also makes sense).. So my question is if you guys know of a mean to get, in the parent class, the name of child class.

  • Get parent attribute within new child form?

This works well and once the new child form submitted it correctly gets associated in the child/parent relationship. What I am trying to do, is lookup values form the parent within the new child form. The problem is that the child relationship is not yet created. Is there anyway I can use a .where lookup in the view? Or, is there a better way of doing this? At the moment I am passing the animal_id though to the new Claim form and it's inserted into a hidden field labelled animal_id. What I am trying to do: <%= @animal.where(:animal_id => params[:animal_id]).id %> The above would ideally get the animal ID from the soon-to-be-associated animal. Is there any sort of before_filter or anything that could take the passed params from the URL and temporarily create the relationship just for the new form view and then permanently create the relationship once the form is submitted? I've tried adding the following to my Claims controller and then called @animal.AnimalName in the view but I get NoMethodError: before_filter :find_animal protected def find_animal if params[:animal_id] Animal.find(params[:animal_id]) end end The URL of the new claim is correctly showing the animal ID so I'm not sure why it's not finding it: http://localhost:3000/claims/new?animal_id=1 The model relations are as follows: animal has_many claims animal has_one exclusion claim has_one animal exception has_one animal

  • Calling an Overridden Method from a Parent-Class Constructor

    - by Vaibhav Bajpai
    I tried calling an overridden method from a constructor of a parent class and noticed different behavior across languages. C++ - echoes A.foo() class A{ public: A(){foo();} virtual void foo(){cout<<"A.foo()";} }; class B : public A{ public: B(){} void foo(){cout<<"B.foo()";} }; int main(){ B *b = new B(); } Java - echoes B.foo() class A{ public A(){foo();} public void foo(){System.out.println("A.foo()");} } class B extends A{ public void foo(){System.out.println("B.foo()");} } class Demo{ public static void main(String args[]){ B b = new B(); } } C# - echoes B.foo() class A{ public A(){foo();} public virtual void foo(){Console.WriteLine("A.foo()");} } class B : A{ public override void foo(){Console.WriteLine("B.foo()");} } class MainClass { public static void Main (string[] args) { B b = new B(); } } I realize that in C++ objects are created from top-most parent going down the hierarchy, so when the constructor calls the overridden method, B does not even exist, so it calls the A' version of the method. However, I am not sure why I am getting different behavior in Java and C#.
