Re: Cursor above siblings
Hi Uli, thanks a lot for the reply! I tried to override mouseMoved:, addCursorRect:cursor:, cursorUpdate:, resetCursorRects, mouseEntered: without calling super, but the I-beam cursor is still set when it is being moved over NSTextView. I also found this in the Cocoa Event Handling Guide docs: Cursor-update events are a special kind of mouse-tracking event that the Application Kit handles automatically. When the mouse pointer enters a cursor rectangle, the Application Kit displays a cursor image appropriate to the type of view under the rectangle; for example, when a mouse pointer enters a text view, an I-beam cursor is displayed. One can read the handles automatically above as no easy way to override. I also think I read somewhere sometime that someone overrode the mouseMoved: method for cursor setting but I cannot find it anymore. However, I'm not sure I understood your last advice: what subview do you mean? Both the button (or the view holding the button) and the textview are siblings. If I make the button a subview of the textarea it wont show up at all..? In any case, I will try to look into this further so if anyone has an idea about this, please let me know.

With a regular view, I would say you just need to create a cursor region around your button that overrides the one set by the other view to set an arrow, but ISTR that cursor regions that overlap have always been kind of unreliable. At least that’s what I’ve found in my testing so far. Sometimes they just don’t seem to trigger. Another problem seems to be that NSTextView seems to not be using cursor views. I have the impression that it just listens for mouseMoved events and re-sets the cursor every time. I still haven’t fully figured out what’s going on here. So in short, you could try to override NSTextView to see if you can get it to not set the cursor at all, then make it use cursor regions instead. If the overlapping of cursor regions doesn’t work sufficiently well, you could make the cursor view aware of the other views’ cursor rects and just have it generate a series of rects with the subviews’ rects cut out, then only set cursor regions for the remaining views. Maybe you’ll have to override mouseMoved: for that, and just not call the inherited method when it’s over a subview.

Yeah, you are probably right...
I did the same, and one thing that looks like it turns off the cursor is
overriding resetCursorRects and updateTrackingAreas to do nothing, and doing
-(void) viewDidMoveToWindow
{
[super viewDidMoveToWindow];
[self.enclosingScrollView setDocumentCursor: nil];
[self.enclosingScrollView updateTrackingAreas];
[self.enclosingScrollView resetCursorRects];
}
That turns off the text view’s cursor, it seems.
Well, I have the custom textview which has empty both resetCursorRects
and updateTrackingAreas, and the snippet from you above, and it still
sets the I-beam cursor. What's more, now it sometimes does not set the
cursor back to the arrow one when I leave the textview area.
I will definitely let you know, if I figure out something useful... One
idea is that I may just drop this floating above approach and do what
NSTextFinder does, namely temporary resize the enclosing scrollview and put
that button over the newly cleaned up area. I would prefer the former,
though, so I will try a bit more.

Cursor above siblings
Hi! I have a window with a custom view, which contains two children: a textview with scrollbars and a button. I would like to overlay the button over the textview so when I click in that area somewhere, the button receives the event before the textview. It kind of works, except for one thing: the cursor is always of the I-beam variety, even when above the button, see [1] and [2]. I think the problem is that the sibling views overlap but don't know how to fix it. I tried to move the button beneath the textview in hierarchy but that doesn't work (button is not shown) and I tried to `addTrackingArea:` but that doesn't work either (maybe I didn't do it the right way but then again, I thought NSButton has its own tracking area). Please, how can I make the cursor change back to the default variety when hovering over the button? I can place the button in a custom view and work with that view, if that helps..?

Few questions about NSTextView
Hi! I'm trying to work with NSTextView but in the course of my learning I encountered several behaviors which I cannot understand why they are happening. Please, I would greatly appreciate if someone could explain in a few words why do they behave like they do and how to achieve the opposite effect. 1. Suppose there is a window which has two NSTextViews in it and each of them uses the findbar (NSTextFinder). The problem is that after closing one findbar (finishing the finding) the cursor jumps to the other textview, i.e. the focus does not return the textview for which the find operation originated. For example: the textviews are side-by-side and the left one has the focus (cursor). When I hit cmd+f, the findbar pop-up and when I hit esc it disappears. But now the cursor jumps to the right textview. I would have thought that it makes sense to return to the textview which I was typing into at first. How do I achieve this? 2. Suppose there is a window with one NSTextView which contains a lot of text so that the scrollbars show up. Now this is very weird and I'm not sure if anyone else can confirm this but I verified it even in TextEdit: when the vertical scrollbar is roughly in 1/4 of the height and I resize the window, the text re-flows immediately as I drag then window border. When the scrollbar is in 3/4 of the height, it re-flows only after releasing the mouse button. Why? Is there a way to make it either re-flow always continuously or never? 3. Similar situation as the second one but this one is even more weird in my eyes. When resizing the window with lots of text, sometimes after releasing the mouse button the cursor jumps/scrolls into middle of the textview and sometimes it does not. I cannot see any pattern, perhaps besides that 1/4 and 3/4 heights but even that doesn't work consistently. My question is, is it possible to disable the centering forever? I.e., when resizing the window, how to make the line at which the text cursor blinks *not* scroll into the middle of textview? I realize the situations might not be very straightforward to picture, I can screen-capture a video or something if there is a need. My hope is that some more experienced developers will recognize these patterns and point me in the right direction because apparently I'm missing something obvious.

NSRegularExpression segfault

Please, can anyone explain to me why does the following program
consistently segfault after 5 characters? I'm running 10.9.5...
#import Cocoa/Cocoa.h
int main () {
NSString *pattern =

NSRegularExpression *expression = [NSRegularExpression

for (NSUInteger i = 0; i 10; i += 1) {
NSString *string = [@ stringByPaddingToLength:i withString:@a
startingAtIndex:0];
NSTextCheckingResult *result = [expression
firstMatchInString:string options:0 range:NSMakeRange(0, i)];
NSLog(@%@, NSStringFromRange([result range]));
}
return 0;
}
It says:
{0, 0}
{0, 1}
{0, 2}
{0, 3}
{0, 4}
{0, 5}
Segmentation fault: 11
Thanks in advance!

Re: Size of NSSplitViewDividerStyleThin
Thanks for the reply! You are right that `splitView:additionalEffectiveRectOfDividerAtIndex:` looks better. I tried id but it still exhibits the said behavior. But I noticed that the grab area is indeed wider than 1px (perhaps it is even 5px!) but the mouse cursor does not turn into `resizeUpDownCursor` (?) when hovering above the divider. Hence it is very confusing why would one want to grab the divider when the cursor is the default text selection one. Btw., when I don't do `setDocumentView` for the textviews, the cursor shows up as expected. Why is this happening? Is it possible to have the resizing cursor over the whole divider frame?

According to the NSScrollViewDelegate documentation: A split view with thin dividers proposes an effective frame that's a little larger than the drawn frame, to make it easier for the user to actually grab the divider.” And AFAICT this is what actually happens in (say) Mail, where the mail list appears to be just a table view in a scroll view. I get more than 1 pixel’s leeway to grab the dividers on each side of it. Anyway, ‘splitView:additionalEffectiveRectOfDividerAtIndex:’ isn’t intended for widening the grab region. It’s for adding a separate rect containing (e.g.) a grabber icon, that’s below or to one side of the divider. The delegate method ‘splitView:effectiveRect:forDrawnRect:ofDividerAtIndex:’ appears to be intended for what you want to do. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Size of NSSplitViewDividerStyleThin
Thanks for the reply again! The problem is I now tried to only copy-paste from the Apple docs and Cocoa with Love and I still get the said behavior. That is, when I move the mouse cursor slowly across the divider it changes back to text selection cursor right after leaving the splitting line. In picture: | | -X--- -- divider X X -- resize cursor | -- text selection cursor | ^ moving mouse from here in the upper direction Why does not the cursor continue to be of the resize variety for the additional 2 pixels?

My guess is that there’s something wrong with the resizing of your text views to fit the scroll view’s container, so near the divider the cursor is over a text view *and* the divider cursor (i.e. grab) rect, and the text view is winning control of the cursor. Possibly your text views are not resizing with the window at all, or possibly they’re resizing but their edges are pinned slightly outside the scroll view’s visible rect. Yet another issue might be the text view’s own insets, which typically provide clearance between the view’s container and the actual text. I believe the default is for some clearance on the sides and maybe the top, but I’m not sure about the bottom. Either way, since the “extra pixels each side of the divider that help to grab it” aren’t part of a divider “view”, I think you’ll have to make sure that the content of the split pane stay far enough away from the divider’s physical thickness to permit this whole “extra pixels” thing to work. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Size of NSSplitViewDividerStyleThin

And everything works fine. The problem begins when I set the style to `NSSplitViewDividerStyleThin`. The gap (grab area) between the two textviews becomes 1px wide and it becomes very diffult to grab the divider and alter the splitting. I tried to add `splitView:additionalEffectiveRectOfDividerAtIndex:` to the delegate, and it even adds the extra rectangle, but it still doesn't work becase the rectangle becomes covered up by the textviews(?). I mean, it is there but I cannot grab it because it is beneath the textviews, so it still effectively is 1px wide. My question is, how to have a thin divider which has wider hit area than 1px? In other words, I like how `NSSplitViewDividerStyleThin` looks and how `NSSplitViewDividerStyleThick` behaves. Is it somehow possible to have both?

Dynamic library linking
Hello,
I have a simple program which I can compile but when I tried to link it
with a dynamic library the linker is not able to find the library, despite
that it is in the same folder as the program.
The longer version: I want to embed Python 3.3 interpreter into simple C
program. I'm on MacOS 10.8, which ships with Python 2.7. I downloaded the
binary distribution of 3.3 version from python.org, copied the dynamic
library from the bundle to a folder, along with all the headers. The
library I copied was a file named Python which had a symlink pointing to
it named libpython3.3m.dylib. Now that the library is in the folder, I
renamed it to python33 so it wouldn't collide with installed Python of
version 2.7.
So the folder has these files: embed.c, python33 and include folder.
The embed.c containts:
#include Python.h
int
main(int argc, char *argv[])
{
Py_Initialize();
PyRun_SimpleString(print 'test'\n);
Py_Finalize();
return 0;
}
and running file python33 says:
python33 (for architecture i386): Mach-O dynamically linked shared
library i386
python33 (for architecture x86_64): Mach-O 64-bit dynamically linked
shared library x86_64
The problem I have is that when try to run:
gcc embed.c -I./include -L. -lpython33
if breaks with:
ld: library not found for -lpython33
Please, does anyone know why?
I guess this is not exactly Cocoa-related question but I tried to ask about
this at various places and I have not found a solution, yet.
I have various theories about why this happens, I would be thankful if
someone could confirm/reject these:
- I cannot just copy out a dynamic library out of a bundle, I have to
install the whole Python 3.3 and after it is properly installed at
particular locations, then I can link with it.
- I'm missing some linker flags. I tried DYLD_LIBRARY_PATH=. but it
didn't help.
- The Python 3.3 library was compiled with different compiler that what I
use to compile my program with.
PS: it compiles with:
gcc embed.c -I./include python33
but when I tun ./a.out it breaks with:
dyld: Library not loaded:
/Library/Frameworks/Python.framework/Versions/3.3/Python
Referenced from: /Users/ecir/Desktop/embed/./a.out
Reason: image not found
Trace/BPT trap: 5
I would really appreciate any hint on how to solve this, thank you in
advace!

have accidentally deleted it. Now it links! So to recap, properly naming
the library (libpython33.so) and compiling with:
gcc embed.c -I./include -L. -lpython33
works! Thank you so much people!
The problem is, as Stephen points out, the executable doesn't run:

What you need to is include the entire Python 3.3 framework in your
Application bundle. Once you've figured out how to do that, linking against
it is as simple as telling Xcode to link the framework. Here are two links

Hello,
I have a simple program which I can compile but when I tried to link it
with a dynamic library the linker is not able to find the library, despite
that it is in the same folder as the program.
The longer version: I want to embed Python 3.3 interpreter into simple C
program. I'm on MacOS 10.8, which ships with Python 2.7. I downloaded the
binary distribution of 3.3 version from python.org, copied the dynamic
library from the bundle to a folder, along with all the headers. The
library I copied was a file named Python which had a symlink pointing to
it named libpython3.3m.dylib. Now that the library is in the folder, I
renamed it to python33 so it wouldn't collide with installed Python of
version 2.7.
So the folder has these files: embed.c, python33 and include folder.
The embed.c containts:
#include Python.h
int
main(int argc, char *argv[])
{
Py_Initialize();
PyRun_SimpleString(print 'test'\n);
Py_Finalize();
return 0;
}
and running file python33 says:
python33 (for architecture i386): Mach-O dynamically linked shared
library i386
python33 (for architecture x86_64): Mach-O 64-bit dynamically linked
shared library x86_64
The problem I have is that when try to run:
gcc embed.c -I./include -L. -lpython33
if breaks with:
ld: library not found for -lpython33
Please, does anyone know why?
I guess this is not exactly Cocoa-related question but I tried to ask
about
this at various places and I have not found a solution, yet.
I have various theories about why this happens, I would be thankful if
someone could confirm/reject these:
- I cannot just copy out a dynamic library out of a bundle, I have to
install the whole Python 3.3 and after it is properly installed at
particular locations, then I can link with it.
- I'm missing some linker flags. I tried DYLD_LIBRARY_PATH=. but it
didn't help.
- The Python 3.3 library was compiled with different compiler that what I
use to compile my program with.
PS: it compiles with:
gcc embed.c -I./include python33
but when I tun ./a.out it breaks with:
dyld: Library not loaded:
/Library/Frameworks/Python.framework/Versions/3.3/Python
Referenced from: /Users/ecir/Desktop/embed/./a.out
Reason: image not found
Trace/BPT trap: 5
I would really appreciate any hint on how to solve this, thank you in
advace!

Thank you for the reply! Unfortunately, there seem to be a tiny bug with
undo. My textview has setRichText: set to NO so that it triggers
the first condition. When the textview looks like this:
aaa
bbb
and I select and copy aaa, then select bbb, delete it by hitting --,
paste aaa, and then I try to undo, it does nothing, i.e. the last line
remains bbb, instead of . In menubar, there it even says Undo Paste
but it does nothing.
Any idea would that could be?

To oversimplify: Menu commands typically go to the first responder — whatever has the UI focus. If the focused object doesn't implement the menu item's method, the event system shops the event up a logical hierarchy called the responder chain (e.g. text field - window - document - application) until it finds an object that does implement the command. The first object that implements the command executes it. File Save Document sends saveDocument: to the first responder. Because the chain goes from bottom up, the saveDocument: message arrives at the document object directly, without mediation from the application's document controller. Thanks. I apologize but I still don't quite understand. If I just implement saveDocument: at the document and leave document controller without it, the menu item is still disabled. When I add saveDocument: to the controller as well, it works. I mean, if I try to visualize it, if I just alloc:init: a document it just floats there in memory, how would a menu know about it? So I need to create it via the document controller, no? If this is the case, how to propagate the saveDocument: event though the document controller to the document? To put it differently, you seems to be saying that that the responder chain flows the other way than what I thought. Ok, but then how does it know about the document? When I were doing this in Xcode, I would just connect the menu item to the first responder and the document from IB would receive the saveDocument:, right? But there has to be a document controller, I imagine it is somehow implied or implicit as in not exposed to the user, which does the heavy lifting, do I understand this correctly? If so, what exactly does this document controller do?

Thank you for the reply! Yes, document-based. However, not sure if it is an issue, but I have my own subclassed window controller. The docs also say that the default for shouldCascadeWindows is YES. I tried to set it to YES in setShouldCascadeWindows:, without luck. I look at the EnhancedDataBurn example but it uses the origin of already shown window, which is slightly different than my case, I believe.

Why's that? Do I have to remember the returned NSPoint and pass it to next cascadeTopLeftFromPoint:? If I remember correctly you are using the document architecture. The documentation has this to say. If you use the Cocoa document architecture, you can use the setShouldCascadeWindows: method of NSWindowController to set whether the window, when it is displayed, should cascade in relation to other document windows (that is, have a slightly offset location so that the title bars of previously displayed windows are still visible). The default is true, so typically you have no additional work to perform. If you are not using the document architecture, you can use the cascadeTopLeftFromPoint: method ofNSWindow to cascade windows yourself. The method returns a point shifted from the top-left corner of the window that can be passed to a subsequent invocation of cascadeTopLeftFromPoint: to position the next window so the title bars of both windows are fully visible. http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/WinPanel/Tasks/SizingPlacingWindows.html Have you examined the EnhancedDataBurn sample code? It has two examples of where -[NSWindow cascadeTopLeftFromPoint:] is used. http://developer.apple.com/library/mac/#samplecode/EnhancedDataBurn/Introduction/Intro.html --Richard ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Window cascading
Thanks! Will look at it. On Tue, May 8, 2012 at 5:22 PM, Richard Somers rsomers...@awinets.comwrote: On May 8, 2012, at 8:51 AM, ecir hana wrote: Yes, document-based.

I look at the EnhancedDataBurn example but it uses the origin of already shown window, which is slightly different than my case, I believe. I would suggest that you download the solutions for Cocoa Programming For Mac OS X (3rd Edition) and look at Chapter 10_Archiving. This chapter contains a modern fully functional document based sample application with window cascading working perfectly. You should be able to quickly get the sample project up and running in a few minutes in Xcode 4.2 by validating the project build settings and setting the default SDK. http://www.bignerdranch.com/book/cocoa_programming_for_mac_os_x_rd_edition_ Subclassing the window controller is a more advanced topic and if I were you I would not focus on that right now. --Richard ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

saveDocument:
Hello,
please, could you clarify one thing for me? In document-based apps, if I
were to implement my own document controller, how would I trigger the
saving of a file? In other words, in menu there is an item which fires
saveDocument: and in document there is a method saveDocument: - how
does the action travels through document controller? In yet another words:
(Menu) saveDocument: - (Document controller) ? - (Document) saveDocument:
Do I have the picture right? Is it ok to write something like (in the
controller):
- (void)saveDocument:(id)sender {
[[self currentDocument] saveDocument:sender];
}
I think I just need to pass saveDocument: from the menu to the document,
am I right?
Kind regards,
Ecir Hana

Re: Minimal document-based app
Thank you all very much, it is much clearer to me now. I'm diving into documentation now... ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Minimal document-based app
Thank you all for the replies!
As I said above, I don't want the question to be whether I should better
use NIBs, or whether Cocoa is more suitable than assembler. I somewhat know
already what the role of NIB is, that it can save time and so on. What I
would like to know is what to do if I was not using NIBs, i.e. if I wanted
to build as much as possible by hand.
To put it in other words, imagine I wanted to go to some city and was
asking about the best spots for hitchhiking. I know it's faster to get
there by a car and that I can use a train. And please, let's not argue
whether I should be hitchhiking in the first place.
Now, I have some code to share!
Please, I think I managed to write an app which seems to be working but I
would like to check whether I missed something. Here what I did:
- I have to use a bundle. That is, a folder with the following structure:
Contents
Contents/Info.plist
Contents/MasOS/executable
- Info.plist has to have:
CFBundleExecutable for executable
CFBundleName for the name of top-most folder (i.e. the bundle filename)
CFBundleDocumentTypes - which I don't yet understand and will get do it
bellow
- then, the other interesting thing I found out is that I don't need to
write AppDelegate (!). So, my main.m looks like:
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
NSApplication * application = [NSApplication sharedApplication];
a menu item which fires newDocument:
[application run];
- then, and this is the interesting bit, newDocument: gets automatically
routed to my NSDocumentClass from Info.plist and there I create the window,
the model, etc.:
- (id)init
{
self = [super init];
if (self) {
NSRect contentSize = NSMakeRect(0.0f, 0.0f, 480.0f, 320.0f);
window = [[NSWindow alloc] initWithContentRect:contentSize
styleMask:NSTitledWindowMask backing:NSBackingStoreBuffered defer:YES];
...
[window makeKeyAndOrderFront:self];
}
return self;
}
And when I hit apple-n, the new window pops-up! I also have to implement
dataOfType: and readFromData: - that comes next.
But I have lots of questions:
- I saw that Xcode named the Info.plist differently (it prepends my project
name to it) - is it ok just to call it Info.plist? Is there any convention?
- this CFBundleDocumentTypes - what if I wanted to have only one kind of
documents? Does it have to be an array as well? What is the absolute
minimum every CFBundleDocumentTypes must contain?
- is it really the case that I don't need the AppDelegate? It currently
makes sense to me but maybe I'm missing something?
- I don't want to put the window in init, where else should I put it? Does
NSDocument have an equivalent of applicationDidFinishLaunching, i.e. when
the document is created is there any callback fired?
- new windows are positioned over the previous ones - I know this is
because of that NSMakeRect() - the application created using Xcode (with
NIBs) put every new window slightly to the right, slightly below the
previous window - what is responsible for it? The NIB?
Lots of questions, I know. Thank you in advance for any help with answering
these!

Re: Minimal document-based app
If nothing else, it would explain to me how things works, 20 lines of code would help me better than 20 documentation pages. There tutorials above certainly did the explaining very well. Also, I don't really want to argue whether there is merit or not - I would be more thankful for the eventual tutorial or code sample.

It's usually misguided to try and build UI in code, it saves you nothing and makes it much harder to get anywhere. Just start a new Cocoa app and use the project template for a document based app. It gives you the necessary starting points, which though it adds a nib, it's extremely small. There is nothing to be gained by going some other route. --Graham On 30/04/2012, at 7:47 AM, ecir hana wrote: Dear list, I'm trying to understand how the things in Cocoa works but I'm struggling with one thing.
