  • Custom view in iPhone SDK gets placed incorrectly in realation to statusbar

    - by markqvist
    (ragh, i'm apparently not allowed to post images, so i have included links to the images in this post instead of embedding them) Im writing an iPhone application based on the navigation controller template, but I am not loading the actual navigation controller as the first view in the window. I create a new view controller from a xib, and then add that as a subview, and then only push the navigation view as a modal when i need it. Here's my application: didFinishLaunching ... method in the application deleate RootViewController *rootViewController = (RootViewController *)[navigationController topViewController]; rootViewController.managedObjectContext = self.managedObjectContext; mainViewController = [[MainViewController alloc] initWithNibName:@"MainViewController" bundle:[NSBundle mainBundle]]; mainViewController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [window addSubview:[mainViewController view]]; [[mainViewController view] setNeedsLayout]; [window makeKeyAndVisible]; return YES; It works but the view is not properly aligned with the statusbar: http://img.exdev.dk/1.png When i click "my ambiances" and push the navigation controller view, and then dismiss it again, the layout is fine: same link as above, just replace the 1 with a 2. Sorry for the hassle, apparently I can also only post one link.... Here's the code I use for presenting/dismissing the navigationcontroller: -(void)pushMyAmbiences { [mainViewController presentModalViewController:navigationController animated:TRUE]; } -(void)returnToMainView { [mainViewController dismissModalViewControllerAnimated:TRUE]; } Is there anything I'm missing here? Layout-wise? Something that needs to be set in the xib? In a vain attempt I tried calling setNeedsLayout on the view, no luck. Any help is greatly appreciated!

  • Select on multiple criteria with XPath

    - by Matt Thrower
    I have an XML document which looks something like this: <meadinkent> <record> <comp_div>MENSWEAR</comp_div> <sty_ret_type>ACCESSORIES</sty_ret_type> <sty_pdt_type>BELTS</sty_pdt_type> <pdt_category>AWESOME_BELTS</pdt_category> </record> <medinkent> I want to useXPath to select nodes which match all four elements and I'm having trouble getting the boolean syntax right. I'm trying this to match the first two just as a test: "/meadinkent/record/comp_div[.='" & comp_div & "'] and /meadinkent/record/sty_ret_type[.='" & sty_ret_type & "']" Which is failing, saying no nodes are returned. Obviously I'm being very stupid - what am I doing wrong? Cheers, mAtt

  • WPF and Prism View Overlay

    - by Zaheer
    Hi, I need some help with overlaying views using the prism framework.Its a little more complexed than that so let me explain.I could be over-thinking this as well :D i have shell (wpf window) and i have 2 views(A & B - both usercontrols) in a module. when the shell loads it loads view A. On view A i have a button to "popup" view B for some user input. so naturally i would think to some sort of modal window/control, maybe even a popup. however the problem i face with the popup is that when i move the shell the popup remains fixed and it doesnt block events in view A. I've tried disabling view A to stop events being fired and i've also tried to use a to get the view B move with the shell. Only the canvas works but i now need a way to block it tho'. Is there anyway i can overlay a view on top of another view with prism? or how does everyone else create modal popups with prism & wpf? any advise or pointers would be greatly appreciated.

  • How to remove view from window?

    - by Wayfarer
    I am using Cocos2D for my main framework. In some cases, I want Cocos2D to load a nib file and have that be the view: window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; TargetPlayerViewController *myController = [[TargetPlayerViewController alloc]initWithNibName:@"TargetPlayerViewController" bundle:nil]; [window addSubview:[myController view]]; [window makeKeyAndVisible]; This works as expected, and shows the TargetPlayerViewController. Wonderful! What I need to know is: once that view has been loaded, how can I have the view remove itself? I've tried a few different ways, but all of them result in the program crashing. To test I have a button on the view set up which triggers this method: - (IBAction)GTFOnow:(id)sender { NSLog(@"GFTO"); window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; //[self.view removeFromSuperview]; //[window makeKeyAndVisible]; } In this method the view should remove itself from the view so I can go back to the Cocos2D. How do I do this?

  • proper way to dynamically assign backbone.js view el

    - by kikuchiyo
    I would like to create two ( or more ) view instances, each with different el attributes, and have events bound to them via backbone.js view's events hash ( not through jQuery ). Getting events to trigger when all instantiations have the same el is easy: someView = Backbone.View.extend({ el: '#someDiv', events: { 'click': 'someFunction' }, someFunction: function(){ //Do something here } }); So far, if I assign el in the initialize function, and set events normally as follows, events do not trigger: someView = Backbone.View.extend({ events: { 'click': 'someFunction' }, initialize: function( options ){ this.el = options.el }, someFunction: function(){ //Do something here } }); My first instinct was to have el be a function that returns the string representation of the dom element of interest: someView = Backbone.View.extend({ el: function(){ return '#someDiv-' + this.someNumber }, events: { 'click': 'someFunction' }, initialize: function( options ){ this.someNumber = options.someNumber }, someFunction: function(){ //Do something here } }); However, this triggers someFunction x times if I have x instantiations of someView. Next I tried setting both the el and events attributes in initialize: someView = Backbone.View.extend({ initialize: function( options ){ this.el = options.el this.events = { 'click': 'someFunction' } }, someFunction: function(){ //Do something here } }); but this does not trigger events. At this point I'm pretty much fishing. Does anyone know how instantiate a backbone.js view with an el specific to that instance that has events that only trigger for that instance, and not other instances of the View?

  • Custom view transition in OpenGL ES

    - by melfar
    I'm trying to create a custom transition, to serve as a replacement for a default transition you would get here, for example: [self.navigationController pushViewController:someController animated:YES]; I have prepared an OpenGL-based view that performs an effect on some static texture mapped to a plane (let's say it's a copy of the flip effect in Core Animation). What I don't know how to do is: grab current view content and make a texture out of it (I remember seeing a function that does just that, but can't find it) how to do the same for the view that is currently offscreen and is going to replace current view are there some APIs I can hook to in order to make my transition class as native as possible (make it a kind of Core Animation effect)? Any thoughts or links are greatly appreciated! UPDATE Jeffrey Forbes's answer works great as a solution to capture the content of a view. What I haven't figured out yet is how to capture the content of the view I want to transition to, which should be invisible until the transition is done. Also, which method should I use to present the OpenGL view? For demonstration purposes I used pushViewController. That affects the navbar, though, which I actually want to go one item back, with animation, check this vid for explanation: http://vimeo.com/4649397. Another option would be to go with presentViewController, but that shows fullscreen. Do you think maybe creating another window (or view?) could be useful?

  • getView only shows Flagged Backgrounds for drawn Views, It does not show Flagged Background when scroll to view more items on list

    - by Leoa
    I am trying to create a listview that receives a flagged list of items to indicate a status to the user. I have been able to create the flag display by using a yellow background (see image at bottom). In Theory, the flagged list can have many flagged items in it. However in my app, only the first three flagged backgrounds are shown. I believe this is because they are initially drawn to the screen. The Flagged background that are not drawn initially to the screen do not show. I'd like to know how to get the remaining flags to show in the list. ListView Recycling: The backgrounds in the listView are being recycled in getView(). This recycling goes from position 0 to position 9. I have flags that need to match at positions 13, 14 and so on. Those positions are not being displayed. listView.getCheckedItemPositions() for multiple selections: This method will not work in my case because the user will not selected the flags. The flags are coming from the server. setNotifyOnChange() and/or public virtual void SetNotifyOnChange (bool notifyOnChange): I'm not adding new data to the list, so I don't see how this method would work for my program. Does this method communicate to getview when it is recycling data? I was unable to find an answer to this in my research. public void registerDataSetObserver: This may be overkill for my problem, but is it possible to have an observer object that keeps track of the all the positions in my items list and in my flag list no matter if the view is recycled and match them on the screen? Code: package com.convention.notification.app; import java.util.Iterator; import java.util.ArrayList; import java.util.List; import android.app.Activity; import android.content.Context; import android.graphics.Color; import android.os.Bundle; import android.text.Html; import android.util.Log; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.view.ViewParent; import android.widget.AdapterView; import android.widget.ArrayAdapter; import android.widget.TextView; public class NewsRowAdapter extends ArrayAdapter<Item> { private Activity activity; private List<Item> items; private Item objBean; private int row; private List<Integer> disable; View view ; int disableView; public NewsRowAdapter(Activity act, int resource, List<Item> arrayList, List<Integer> disableList) { super(act, resource, arrayList); this.activity = act; this.row = resource; this.items = arrayList; this.disable=disableList; System.out.println("results of delete list a:"+disable.toString()); } public int getCount() { return items.size(); } public Item getItem(int position) { return items.get(position); } public long getItemId(int position) { return position; } @Override public int getItemViewType(int position) { for(int k =0;k < disable.size();k++){ if(position==disable.get(k)){ //System.out.println( "is "+position+" value of disable "+disable.get(k)); disableView=disable.get(k); //AdapterView.getItemAtPosition(position); } } return position; } @Override public View getView(final int position, View convertView, ViewGroup parent) { View view = convertView; ViewHolder holder; if (view == null) { LayoutInflater inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); view = inflater.inflate(row, null); getItemViewType(position); long id=getItemId(position); if(position==disableView){ view.setBackgroundColor(Color.YELLOW); System.out.println(" background set to yellow at position "+position +" disableView is at "+disableView); }else{ view.setBackgroundColor(Color.WHITE); System.out.println(" background set to white at position "+position +" disableView is at "+disableView); } //ViewHolder is a custom class that gets TextViews by name: tvName, tvCity, tvBDate, tvGender, tvAge; holder = new ViewHolder(); /* setTag Sets the tag associated with this view.

The header is followed by a number of dashes. My issue is that, in the data, you see a number of entries where the cease time is NULL i.e event is still active. All such entries must go i.e for each element where the alarm cease time is NULL, the start time, the cease time(in this case NULL) and the actual element must be deleted from the file. In the remaining data, all the text starting from word SubNetwork upto BtsSiteMgr= must also go. Along with the headers and the dashes.

  • iphone - moving from one view to another

    - by codemonkey
    Hi there, I am getting started with iphone development and am trying to move from one view to another. I have a main view (NearestPhotosViewController) which basically acts as a menu for my app. I then have a second view (DisplayNearestPhotos). I come from a web (html) background so what i'm trying to do here in web terms is click a button (link) on the NearestPhotosViewController view to then display the DisplayNearestPhotos view. I have been looking around for some code to do this (I don't think it's as simple as doing the equivelent in html). The following code is hooked up to a button on my menu view. -(IBAction)ButtonPressed:(id)sender { DisplayNearestPhotos *views = [[DisplayNearestPhotos alloc] initWithNibName:nil bundle:nil]; [self presentModalViewController:views animated:YES]; views.release; } The above code works (it displays the second view) but what i'd like to know is, is that the correct way to do it? If not, what is the correct way to move from one view to another? Thank you in advance

  • postgres counting one record twice if it meets certain criteria

    - by Dashiell0415
    I thought that the query below would naturally do what I explain, but apparently not... My table looks like this: id | name | g | partner | g2 1 | John | M | Sam | M 2 | Devon | M | Mike | M 3 | Kurt | M | Susan | F 4 | Stacy | F | Bob | M 5 | Rosa | F | Rita | F I'm trying to get the id where either the g or g2 value equals 'M'... But, a record where both the g and g2 values are 'M' should return two lines, not 1. So, in the above sample data, I'm trying to return: $q = pg_query("SELECT id FROM mytable WHERE ( g = 'M' OR g2 = 'M' )"); 1 1 2 2 3 4 But, it always returns: 1 2 3 4

    0 vote down star I have used hibernate to fetch the login information from the mysql database. But the problem is that say for example the user name is 'dhiraj' in the database, now the login is successful by entering the user name, but it is also allowing to enter by taking the user name in uppercase also, e.g., 'DHIRAJ'. I want to restrict it to as it in the database. Can you tell me how to achieve that in hibernate?

  • Deleting a Collection with NHibernate Using the Criteria API

    - by lomaxx
    I think I know what the answer to this question is probably going to be, but I thought I'd go ahead and ask it anyway. It appears that within NHibernate if I do something like this: IList<Customer> customers = Session.CreateCriteria(typeof(Customer)) .Add(Restrictions.Eq("Name", "Steve") .List<Customer>(); And I want to then delete that list of customers. From what I can tell the only way to do it is like this: foreach(var customer in customers) { Session.Delete(customer); } But what I'm wondering is if there's any way I can just go: Session.Delete(customers); And delete the entire collection with a single call?

  • Android: FragmentAdapter and pageview do not update the view

    - by user1240937
    My trouble is: when i get new data, my viewpager that use my custom adapter do not update view. I discovered that many programmer got same bug, so i tried a lot of suggestion but no way works for me. So tired. One more time, read my source and help me understand why i fail with updating view pleaseee! Here is my FragmentAdapter: private class SwipeyTabsPagerAdapter extends FragmentPagerAdapter implements SwipeyTabsAdapter { private final Context mContext; private String[] datas; public SwipeyTabsPagerAdapter(Context context, FragmentManager fm, String[] ds) { super(fm); this.mContext = context; datas=ds; } @Override public int getItemPosition(Object object) { return POSITION_NONE; } @Override public Fragment getItem(int position) { Log.e("new item:", datas[position]); return SwipeyTabFragment.newInstance(datas[position]); } @Override public int getCount() { return datas.length; } public TextView getTab(final int position, SwipeyTabs root) { TextView view = (TextView) LayoutInflater.from(mContext).inflate( R.layout.swipey_tab_indicator, root, false); view.setText(datas[position]); view.setOnClickListener(new OnClickListener() { public void onClick(View v) { mViewPager.setCurrentItem(position); } }); return view; } } and here is where i set adapter: SwipeyTabsPagerAdapter adapter = new SwipeyTabsPagerAdapter(getApplicationContext(), getSupportFragmentManager(),dicts); mViewPager.setAdapter(adapter); mTabs.setAdapter(adapter); mViewPager.getAdapter().notifyDataSetChanged(); By logcat, can see clearly that: only first time, newItem be processed, so view can not be update.

  • iOS Switching an embedded view in storyboard

    - by Coyote6
    I have been trying to figure this out all day and I know it should be able to be done, but being new to iOS development using Objective-C and not Appcelerator I'm having newbie issues. What I am trying to accomplish is to have an embedded view in one of my other views, but to be able to switch which view is embedded through programming. I am using storyboards. When I tried to use the view container it displays the attached view, but I cannot attach multiple views to the container in the storyboard. I drew up an image, but to my annoyance I cannot post an image on here because I don't have enough "rep" points, so I posted it on my site: http://static.c6gx.com/images/iphone-embedded-views-diagram.jpg Later on I would like what appears to be a push segue, within that view container, but first I just want to be able to switch between embedded view 1, 2, 3, etc. Am I supposed to be using a view container to accomplish this, or some other type of controller? Then how would I call the transition to change the view? Thank you for any help you can provide.

  • JPA2 adding referential contraint to table complicates criteria query with lazy fetch, need advice

    - by Quaternion
    Following is a lot of writing for what I feel is a pretty simple issue. Root of issue is my ignorance, not looking so much for code but advice. Table: Ininvhst (Inventory-schema inventory history) column ihtran (inventory history transfer code) using an old entity mapping I have: @Basic(optional = false) @Column(name = "IHTRAN") private String ihtran; ihtran is really a foreign key to table Intrnmst ("Inventory Transfer Master" which contains a list of "transfer codes"). This was not expressed in the database so placed a referential constraint on Ininvhst re-generating JPA2 entity classes produced: @JoinColumn(name = "IHTRAN", referencedColumnName = "TMCODE", nullable = false) @ManyToOne(optional = false) private Intrnmst intrnmst; Now previously I was using JPA2 to select the records/(Ininvhst entities) from the Ininvhst table where "ihtran" was one of a set of values. I used in.value() to do this... here is a snippet: cq = cb.createQuery(Ininvhst.class); ... In in = cb.in(transactionType); //Get in expression for transacton types for (String s : transactionTypes) { //has a value in = in.value(s);//check if the strings we are looking for exist in the transfer master } predicateList.add(in); My issue is that the Ininvhst used to contain a string called ihtran but now it contains Ininvhst... So I now need a path expression: this.predicateList = new ArrayList<Predicate>(); if (transactionTypes != null && transactionTypes.size() > 0) { //list of strings has some values Path<Intrnmst> intrnmst = root.get(Ininvhst_.intrnmst); //get transfermaster from Ininvhst Path<String> transactionType = intrnmst.get(Intrnmst_.tmcode); //get transaction types from transfer master In<String> in = cb.in(transactionType); //Get in expression for transacton types for (String s : transactionTypes) { //has a value in = in.value(s);//check if the strings we are looking for exist in the transfer master } predicateList.add(in); } Can I add ihtran back into the entity along with a join column that is both references "IHTRAN"? Or should I use a projection to somehow return Ininvhst along with the ihtran string which is now part of the Intrnmst entity. Or should I use a projection to return Ininvhst and somehow limit Intrnmst just just the ihtran string. Further information: I am using the resulting list of selected Ininvhst objects in a web application, the class which contains the list of Ininvhst objects is transformed into a json object. There are probably quite a few serialization methods that would navigate the object graph the problem is that my current fetch strategy is lazy so it hits the join entity (Intrnmst intrnmst) and there is no Entity Manager available at that point. At this point I have prevented the object from serializing the join column but now I am missing a critical piece of data. I think I've said too much but not knowing enough I don't know what you JPA experts need. What I would like is my original object to have both a string object and be able to join on the same column (ihtran) and have it as a string too, but if this isn't possible or advisable I want to hear what I should do and why. Pseudo code/English is more than fine.

  • Python: Taking an array and break it into subarrays based on some criteria

    - by randombits
    I have an array of files. I'd like to be able to break that array down into one array with multiple subarrays, each subarray contains files that were created on the same day. So right now if the array contains files from March 1 - March 31, I'd like to have an array with 31 subarrays (assuming there is at least 1 file for each day). In the long run, I'm trying to find the file from each day with the latest creation/modification time. If there is a way to bundle that into the iterations that are required above to save some CPU cycles, that would be even more ideal. Then I'd have one flat array with 31 files, one for each day, for the latest file created on each individual day.

  • LINQ to SQL Where Clause Optional Criteria

    - by RSolberg
    I am working with a LINQ to SQL query and have run into an issue where I have 4 optional fields to filter the data result on. By optional, I mean has the choice to enter a value or not. Specifically, a few text boxes that could have a value or have an empty string and a few drop down lists that could have had a value selected or maybe not... For example: using (TagsModelDataContext db = new TagsModelDataContext()) { var query = from tags in db.TagsHeaders where tags.CST.Equals(this.SelectedCust.CustCode.ToUpper()) && Utility.GetDate(DateTime.Parse(this.txtOrderDateFrom.Text)) <= tags.ORDDTE && Utility.GetDate(DateTime.Parse(this.txtOrderDateTo.Text)) >= tags.ORDDTE select tags; this.Results = query.ToADOTable(rec => new object[] { query }); } Now I need to add the following fields/filters, but only if they are supplied by the user. Product Number - Comes from another table that can be joined to TagsHeaders. PO Number - a field within the TagsHeaders table. Order Number - Similar to PO #, just different column. Product Status - If the user selected this from a drop down, need to apply selected value here. The query I already have is working great, but to complete the function, need to be able to add these 4 other items in the where clause, just don't know how!
