  • Loading a UIView from a UITableview

    - by Michael Robinson
    I can firgure out how to push a UIView from a Tableview and have the "child" details appear. Here is the view I'm trying to load: Here is the code that checks for children and either pushes a itemDetail.xib or an additional UITable, I want to use the above .xib but load the correct contents "tableDataSource" into the UItable: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //Get the dictionary of the selected data source. NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row]; //Get the children of the present item. NSArray *Children = [dictionary objectForKey:@"Children"]; if([Children count] == 0) { ItemDetailViewController *dvController = [[ItemDetailViewController alloc] initWithNibName:@"ItemDetailView" bundle:[NSBundle mainBundle]]; [self.navigationController pushViewController:dvController animated:YES]; [dvController release]; } else { //Prepare to tableview. FirstTab *rvController = [[FirstTab alloc] initWithNibName:@"FirstView" bundle:[NSBundle mainBundle]]; //Increment the Current View rvController.CurrentLevel += 1; //Set the title; rvController.CurrentTitle = [dictionary objectForKey:@"Title"]; //Push the new table view on the stack [self.navigationController pushViewController:rvController animated:YES]; rvController.tableDataSource = Children; [rvController release]; } } Thanks for the help. I see lots of stuff on this but can't find the correct push instructions.

  • Android onFling not responding

    - by Kevin Moore
    I am new to android first of all so think of any newbie mistakes first I am trying to add a fling function in my code. public class MainGamePanel extends SurfaceView implements SurfaceHolder.Callback, OnGestureListener { private MainThread thread; private Droid droid; private Droid droid2; private static final String TAG = gameView.class.getSimpleName(); private GestureDetector gestureScanner; public MainGamePanel(Context context){ super(context); getHolder().addCallback(this); droid = new Droid(BitmapFactory.decodeResource(getResources(), R.drawable.playerbox2), 270, 300); droid2 = new Droid(BitmapFactory.decodeResource(getResources(), R.drawable.playerbox2), 50, 300); thread = new MainThread(getHolder(), this); setFocusable(true); gestureScanner = new GestureDetector(this); } public boolean onTouchEvent(MotionEvent event){ return gestureScanner.onTouchEvent(event); } @Override protected void onDraw(Canvas canvas){ canvas.drawColor(Color.BLACK); droid.draw(canvas); droid2.draw(canvas); } @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { droid.setX(50); droid.setY(50); Log.d(TAG, "Coords: x=" + e1.getX() + ",y=" + e2.getY()); return true; } @Override public boolean onDown(MotionEvent e) { droid2.setX((int)e.getX()); droid2.setY((int)e.getY()); Log.d(TAG, "Coords: x=" + e.getX() + ",y=" + e.getY()); return false; } I got the gestureListener to work with: onDown, onLongPress, and onShowPress. But i can't get any response with onFling, onSingleTapUp, and onScroll. What mistake am I making? does it have to do with views? I don't know what code would be useful to see.... so any suggestions would be much appreciated. Thank You!

  • Help regarding multi-threading in MFC,please help me firends!

    - by kiddo
    Hello all,in my application there is a small part of function,in which it will read files to get some information,the number of filecount would be utleast 50,So I thought of implementing threading.Say if the user is giving 50 files,I wanted to separate it as 5 *10, 5 thread should be created,so that each thread can handle 10 files which can speed up the process.And also from the below code you can see that some variables are common.I read some articles about threading and I am aware that only one thread should access a variable/contorl at a me(CCriticalStiuation can be used for that).For me as a beginner,I am finding hard to imlplement what I have learned about threading.Somebody please give me some idea with code shown below..thanks in advance file read function:// void CMyClass::GetWorkFilesInfo(CStringArray& dataFilesArray,CString* dataFilesB, int* check,DWORD noOfFiles,LPWSTR path) { CString cFilePath; int cIndex =0; int exceptionInd = 0; wchar_t** filesForWork = new wchar_t*[noOfFiles]; int tempCheck; int localIndex =0; for(int index = 0;index < noOfFiles; index++) { tempCheck = *(check + index); if(tempCheck == NOCHECKBOX) { *(filesForWork+cIndex) = new TCHAR[MAX_PATH]; wcscpy(*(filesForWork+cIndex),*(dataFilesB +index)); cIndex++; } else//CHECKED or UNCHECKED { dataFilesArray.Add(*(dataFilesB+index)); *(check + localIndex) = *(check + index); localIndex++; } } WorkFiles(&cFilePath,dataFilesArray,filesForWork, path, cIndex); dataFilesArray.Add(cFilePath); *(check + localIndex) = CHECKED; }

  • Changing UIViews during UIInterfaceOrientation on iPad

    - by FreeAppl3
    I am trying to change views on rotation because my views have to be significantly different from portrait to landscape. Now the code I am using works once then the app freezes when trying to rotate back. Either direction does not make a difference. For example: If I am in Landscape and rotate to portrait everything works great until I rotate back to landscape then it freezes and does absolutely nothing. Here is the code I am using to achieve this In my "viewDidLoad" method [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didRotate:) name:UIDeviceOrientationDidChangeNotification object:nil]; Then I call this for the rotation: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return YES; } - (void)didRotate:(NSNotification *)notification { UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation]; if ((orientation == UIDeviceOrientationLandscapeLeft) || (orientation == UIDeviceOrientationLandscapeLeft)) { // present the other viewController, it's only viewable in landscape [self.view addSubview:landScapeView]; } if ((orientation == UIDeviceOrientationLandscapeRight) || (orientation == UIDeviceOrientationLandscapeRight)) { // present the other viewController, it's only viewable in landscape [self.view addSubview:landScapeView]; } else if ((orientation == UIDeviceOrientationPortrait || (orientation == UIDeviceOrientationPortrait)) { // get rid of the landscape controller [self.view addSubview:portrait]; } else if ((orientation == UIDeviceOrientationPortraitUpsideDown || (orientation == UIDeviceOrientationPortraitUpsideDown)) { // get rid of the landscape controller [self.view addSubview:portrait]; } }

  • Generics Java and Shadowing of type parameters

    - by rubixibuc
    This code seems to work fine class Rule<T> { public <T>Rule(T t) { } public <T> void Foo(T t) { } } Does the method type parameter shadow the class type parameter? Also when you create an object does it use the type parameter of the class? example Rule<String> r = new Rule<String>(); Does this normally apply to the type parameter of the class, in the situation where they do not conflict? I mean when only the class has a type parameter, not the constructor, or does this look for a type parameter in the constructor? If they do conflict how does this change? SEE DISCUSSION BELOW if I have a function call x = <Type Parameter>method(); // this is a syntax error even inside the function or class ; I must place a this before it, why is this, and does everything still hold true. Why don't I need to prefix anything for the constructor call. Shouldn't Oracle fix this.

  • casting char[][] to char** causes segfault?

    - by Earlz
    Ok my C is a bit rusty but I figured I'd make my next(small) project in C so I could polish back up on it and less than 20 lines in I already have a seg fault. This is my complete code: #define ROWS 4 #define COLS 4 char main_map[ROWS][COLS+1]={ "a.bb", "a.c.", "adc.", ".dc."}; void print_map(char** map){ int i; for(i=0;i<ROWS;i++){ puts(map[i]); //segfault here } } int main(){ print_map(main_map); //if I comment out this line it will work. puts(main_map[3]); return 0; } I am completely confused as to how this is causing a segfault. What is happening when casting from [][] to **!? That is the only warning I get. rushhour.c:23:3: warning: passing argument 1 of ‘print_map’ from incompatible pointer type rushhour.c:13:7: note: expected ‘char **’ but argument is of type ‘char (*)[5]’ Are [][] and ** really not compatible pointer types? They seem like they are just syntax to me.

  • Saving image to the existing file throws "A generic error occurred in GDI+" error.

    - by ryan
    i am trying to create a overlapped image using different images,then saving to a particular location. so that i can use generated image(overlapped img) in my telerik reporting. it is important to me to save the overlapped image to the same location with same name. but generating this overlapped image second time throws throws "A generic error occurred in GDI+" error. Please help me with this. It seems i can not override the existing image file. i tried deleting the existing image every time i generate the new one. but its not allowing me deleting the file ,may be it is used by telerik reporting. Here is the image create method which takes the baseimage path, sectionimage path and the reportimage path (this is the target locationenter code here) public static void Creat(List<string> sectionNames, string reportImagePath, string baseImagePath) { var file = Image.FromFile(baseImagePath); Graphics g = Graphics.FromImage(file); foreach (var sectionName in sectionNames) { var image = Image.FromFile(sectionName); g.DrawImage(image, new PointF(0.0F, 0.0F)); } file.Save(reportImagePath, ImageFormat.Png); file.Dispose(); }

  • How to sort NSMutableArray? Code review needed

    - by JAM
    Good evening. This code works. It sorts an array of cards by both Suit and Card Value. It is also very much brute force. Can you recommend a better way? Does Objective-C help dealing with a situation where object being sorted itself has multiple fields, on which sorting depends? -(void) sort: (NSMutableArray *) deck { NSUInteger count = [deck count]; Card *thisCard; Card *nextCard; int this; int next; BOOL stillSwapping = true; while (stillSwapping) { stillSwapping = false; for (NSUInteger i = 0; i < count; ++i) { this = i; next = i+1; if (next < count) { thisCard = [deck objectAtIndex:this]; nextCard = [deck objectAtIndex:next]; if ([thisCard suit] > [nextCard suit]) { [deck exchangeObjectAtIndex:this withObjectAtIndex:next]; stillSwapping = true; } if ([thisCard suit] == [nextCard suit]) { if ([thisCard value] > [nextCard value]) { [deck exchangeObjectAtIndex:this withObjectAtIndex:next]; stillSwapping = true; } } } } } }

    I am creating dynamic labels and letting users change attributes of the labes like backcolor and so by sending unicode. However I don't know how to check if the label exists therefore I can't manipulate the dynamicly created label. below is my code: if ((InputBox.Text.StartsWith("p")) && (InputBox.Text.EndsWith("}")))// only process if the message starts with p and ends with } { string Message = InputBox.Text; InputBox.Text = "";// Clear the box when done. // Butt1 message line if (Message.StartsWith("plabelt1")) { if (Message.StartsWith("plabelt1_BackColor")) { Message = Message.Substring(19); //labelt1.BackColor = System.Drawing.Color.FromName(Message.Replace("}", "")); } } private void ImageBox_DragDrop(object sender, DragEventArgs e) { //Graphics g = ImageBox.CreateGraphics(); //g.DrawImage((Image)e.Data.GetData(DataFormats.Bitmap), //new Point(e.X - this.Left, e.Y - this.Top - 150)); Point p2 = PointToClient(Cursor.Position); Label buttlbl_ = new Label(); labelCount++; buttlbl_.Name = "labelt" + labelCount.ToString(); buttlbl_.Location = new Point(p2.X, p2.Y); buttlbl_.Size = new System.Drawing.Size(37, 37); buttlbl_.BackColor = System.Drawing.Color.DarkGray; this.Controls.Add(buttlbl_); buttlbl_.BringToFront(); ImageBox.Invalidate(); } } Any suggestions?

  • How to optimize this simple function which translates input bits into words?

    - by psihodelia
    I have written a function which reads an input buffer of bytes and produces an output buffer of words where every word can be either 0x0081 for each ON bit of the input buffer or 0x007F for each OFF bit. The length of the input buffer is given. Both arrays have enough physical place. I also have about 2Kbyte free RAM which I can use for lookup tables or so. Now, I found that this function is my bottleneck in a real time application. It will be called very frequently. Can you please suggest a way how to optimize this function? I see one possibility could be to use only one buffer and do in-place substitution. void inline BitsToWords(int8 *pc_BufIn, int16 *pw_BufOut, int32 BufInLen) { int32 i,j,z=0; for(i=0; i<BufInLen; i++) { for(j=0; j<8; j++, z++) { pw_BufOut[z] = ( ((pc_BufIn[i] >> (7-j))&0x01) == 1? 0x0081: 0x007f ); } } } Please do not offer any compiler specific or CPU/Hardware specific optimization, because it is a multi-platform project.

  • iOS: Best Way to do This w/o Calling Method 32 Times?

What's the best way of achieving this? Using a third party tool (Game Center Manager), I can get the following line to return a dictionary with leaderboard ID's as keys and the Top 1 highest score as values NSDictionary *highScores = [[GameCenterManager sharedManager] highScoreForLeaderboards:leaderboardIDs]; So my question is, how can I combine those 2 segments of code to pull in the 100 values for each leaderboard, resulting in a dictionary with all of the leaderboard names as keys, and the Total (of each 100 scores) of the leaderboards for values.

  • Get class instance by class name string

    - by VDVLeon
    Hi all, I noticed the function Object.factory(char[] className) in D. But it does not work like I hoped it would work; it does not work ;) An example: import std.stdio; class TestClass { override string toString() { return typeof(this).stringof; // TestClass } }; void main(string[] args) { auto i = Object.factory("TestClass"); if (i is null) { writeln("Class not found"); } else { writeln("Class string: " ~ i); } } I think this should result in the message: "Class string: TestClass" but it says "Class not found". Does anybody know why this happens and how I could fix it ? Or do I need to make my own class factory. For example by make a class with a static array Object[string] classes; with class instances. When I want a new instance I do this: auto i = (className in classes); if (i is null) { return null; } return i.classinfo.create();

  • NSView only redraws on breakpoint

    - by Jacopo
    I have a custom view inside a NSPopover. It should change according to user input and it does the first time the user interact with it but it fails to redraw the following times. I have tried to put an NSLog inside the -drawRect: method and it doesn't get called during normal execution. When I try to debug and put a breakpoint inside the method it gets called normally and the app works as it should. I explicitly call the view -setNeedsDisplay: method every time I need it to redraw. I don't understand why it should make a difference. Here is the code that update the status of the view. These methods are part of the NSTextField delegate method -textDidChange: and I checked that these get called every time the user type something in the textfield associated with popover. [tokenCloud tokensToHighlight:[NSArray arrayWithObject:completeSuggestionString]]; tokenCloud.tokens = filteredTokens; [tokenCloud setNeedsDisplay:YES]; The views is a series of recessed button. The first line update the status of all the buttons in the popover and the second add or delete buttons. They both work properly because the first time they are called the view is update properly. I have also checked that both the status of the buttons in tokenCloud and its property tokens are updated correctly. The problem is that the NSView subclass, tokenCloud, doesn't redraw so the changes are not reflected in the UI the second time. Here is the draw method of the view: - (void)drawRect:(NSRect)rect { [self recalculateButtonLocations]; NSLog(@"Redrawn"); } Again this method gets called normally every time I update the view if I place a breakpoint in [self recalculateButtonLocations];. If instead I let the app run normally nothing gets logged in the console the second time I update the view. Same thing if I include the NSLog in the recalculateButtonLocations method, nothing gets logged the second time meaning that the method is not called.

  • Redirect To Another Site With Header Information Attached Javascript

I have a scene with a waiter holding a tray of food (the food is a random CCSprite choosen from an array) each time he comes onscreen he holds a new piece of food (the user touches the food and the waiter walks off to return again with a new piece of food however I cant seem to delete the old peice of food from the screen as it says the child is already added... any help would be great -(id) init { ///other code then... waiterOnSCreen = [CCSprite spriteWithSpriteFrameName:@"CatUP.png"]; waiterOnSCreen.position = ccp(CatOffSCreenPosX, catXpos); [self addChild:waiterOnSCreen z:0]; //moving the waiter // the random food sprite is added later to the waiter // [waiterOnSCreen addChild:myRandomSprite]; } -(void)LoadRandomFood { ///I make my array here then... int i = arc4random() % [RandomFood count]; myRandomSprite = (CCSprite *)[RandomFood objectAtIndex:i]; //waiterOnSCreen is a CCSprite added on the init [waiterOnSCreen addChild:myRandomSprite]; myRandomSprite.position=ccp(290,220); myRandomSprite.tag = RandomFoodTag; } } later in if(CGRectContainsPoint(waiterOnSCreen.boundingBox, location)) { //trying to remove the food here //Ive already tried to remove the sprite using [self removeChildByTag:RandomeObjectTag]; //and also CCSprite *wantedSprite = (CCSprite *)[self getChildByTag:RandomFoodTag]; [wantedSprite removeFromParentAndCleanup:YES]; } }

  • C++: Help with cin difference between Linux and Windows

    - by Krashman5k
    I have a Win32 console program that I wrote and it works fine. The program takes input from the user and performs some calculations and displays the output - standard stuff. For fun, I am trying to get the program to work on my Fedora box but I am running into an issue with clearing cin when the user inputs something that does not match my variable type. Here is the code in question: void CParameter::setPrincipal() { double principal = 0.0; cout << endl << "Please enter the loan principal: "; cin >> principal; while(principal <= 0) { if (cin.fail()) { cin.clear(); cin.ignore(INT_MAX, '\n'); } else { cout << endl << "Plese enter a number greater than zero. Please try again." << endl; cin >> principal; } } m_Parameter = principal; } This code works in Windows. For example, if the user tries to enter a char data type (versus double) then the program informs the user of the error, resets cin, and allows the user another opportunity to enter a valid value. When I move this code to Fedora, it compiles fine. When I run the program and enter an invalid data type, the while loop never breaks to allow the user to change the input. My questions are; how do I clear cin when invalid data is inputted in the Fedora environment? Also, how should I write this code so it will work in both environments (Windows & Linux)? Thanks in advance for your help!

  • ListView and wrap_content

    - by gaiapac
    I want to create an activity with a ListView on the left and a TextView on the right, side by side. I write the following xml, but the ListView occupies the entire page and it don't worry about the wrap_content. Why? How can I resolve it? <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > <ListView android:id="@+id/lv" android:layout_width="wrap_content" android:layout_height="match_parent" /> <TextView android:id="@+id/tv" android:layout_width="wrap_content" android:layout_height="match_parent" /> </LinearLayout> EDIT: my onCreate @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ListView lv = (ListView) findViewById(R.id.lv); String[] values = new String[] { "Test1", "Test2", "Test3", "Test4" }; ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.layout.left, R.id.tv1, values); lv.setAdapter(adapter); }
