Changing NSPrintPanel UI in 10.5
Hello, I am interested in adding additional button to the NSPrintPanel dialog at the very bottom line. Between ( PDF v ) and ( Cancel ). Is that possible under Leopard? Custom accessory view is not suitable for me. Even topics from "Extending Printing Dialogs" does not help, because they does not cover information about how to modify PrintPanel UI outside changeable panes. I could do this by getting NSPrintPanel window, accessing its content view and so on... but I wanted to be sure that this is the only way to do that. Is there any "right way" to achieve this?

Re: Changing NSPrintPanel UI in 10.5
Thank you for reply. > What are you trying to accomplish? Basicaly I am trying to merge "Page setup" and "Print" dialogs. That is easy by using NSPrintPanel's setOptions. But I want to keep "Page setup" functionality also. I mean, I want to be able to change paper size for example, without printing. This is quite difficult to do that when having only "Cancel" and "Print" buttons.

Re: Changing NSPrintPanel UI in 10.5
You are right. And that works very well. Except one thing. After changing paper size in Print dialog I have two options - to press Cancel (and revert changes I have made) or to press Print and save new options + print document. I want only to change paper size and save that information for later print. I do not want to print at this moment. In other words, I want to have Print and Page Setup (without printing) functionality in one (Print) dialog. > This is already handled inside the existing print dialog, although not in > its collapsed state.

Katoeri-Hiragana input underline drawing
Hello, I am wondering if it is possible to draw this underline manually? I am talking about underline which is visible when entering text in Katoeri-Hiragana and characters are in undermined state. I have tried to use "- (void)drawGlyphsForGlyphRange:(NSRange)glyphsToShow atPoint:(NSPoint)origin" and "- (void)drawBackgroundForGlyphRange:(NSRange)glyphsToShow atPoint:(NSPoint)origin". But these methods doesn't draw underline. I have noticed, that marked text range is exactly what I want, but the problem is - how to know WHEN underline is required? TextView markedTextAttributes returns dictionary, which has only yellow background. The same you can see when entering Opt+e, for example. Looks like this depends on input locale. But I have no idea how Katoeri-Hiragana should be detected. Any kind of help is very appreciate.

Text layout responsibility
Hello list, I have performed quick search through the list and couldn't find answer to my question. I am trying to implement editable text view which changes text position (paragraphs positions, to be exact) according to the some text attributes. I know, that NSTextContainer is responsible for line rects calculation when text should be placed in known shape. Is it responsible for this when position depends on text attributes also? Reason I am asking is that in method lineFragmentRectForProposedRect:sweepDirection:movementDirection:remainingRect: I do not have any information about glyphs or characters range to be placed in proposed rect, only rect coordinates. Should I do this manually by accessing container -> text view -> text storage? Maybe NSLayoutManager or NSTypeSetter subclass would be better choice? Another thing I'd like to ask, is where should I adjust text view/text container size if this is necessary while typing? I have tried to do this after getting NSTextStorageDidProcessEditingNotification notification. But that raises an exception: >> Exception raised during posting of notification. Ignored. exception: '*** >> NSRunStorage, _NSBlockNumberForIndex(): index (0) beyond array bounds (0)' >> invoked observer method: '*** -[MyTestController >> _TextStorageContentChanged:]' observer: 0x14d60b10 notification name: >> 'NSTextStorageDidProcessEditingNotification' << Any help is very appreciate.

Properly symbol fonts handling in Cocoa
Hello list, Last few days I was trying to understand how symbol fonts (wingdings, webdings X, etc) should be properly handled with cocoa text system. As a good example could be Adobe Photoshop and Apple Pages. Both behaves in the same way and I want to achieve the same result. For example if I choose Wingdings font and type "PO", I see two flag symbols. If I change font to any other (Arial, Times, Helvetica etc.) I see characters I have entered by keyboard layout (PO). Also, If I copy text while Wingdings font is selected, and paste it to another app, I am getting "PO". Searching through the list gave me few ideas. But none of them I found very useful. One of them is to map characters to different codes (by adding 0x00F000). This works, but I doubt this is correct way, because that brakes copy/paste mechanism and when converting back to Arial/Times.. symbols needs to be remapped again. Unless this could be done in auto way. I think only glyphs should be used from font and mapping should be done by text system. The problem is - I have no idea how to do that. Any help is appreciate. P.S. default behavior is like TextEdit: say we have "PO" and after choosing Wingdings font is changed to default Lucida Grande.

Custom field editor context menu
Hello list,
Congrats on WWDC week. Have great sessions :)
I have some troubles implementing custom context menu in NSTextField.
While field is editing, field editor take control over field. So I
implemented my custom field editor:
- (id)windowWillReturnFieldEditor:(NSWindow *)sender toObject:(id)client
{
if (sender && client are OK)
{
static MyCustomFieldEditorView *_editor = nil;
if (_editor == nil)
{
_editor = [[MyCustomFieldEditorView alloc]
initWithFrame:[(NSTextField*)client frame]];
}
[_editor setMenu:[(NSTextField*)client menu]];
return _editor;
}
return nil;
}
Field editor is replaced with my own one, my menu is displayed. Great.
But that works if there is no selected text in editor. But if any, I
am getting:
Spelling suggestion 1
Spelling suggestion 2
...
Spelling suggestion N
-
Ignore Spelling
Learn Spelling
-
Search in Spotlight
Search in Google
-
Look up in Dictionary
-
My Custom menu item 1
...
My Custom menu item N
I want menu to have only my custom items. No spelling & co above my
items. Always. Even with some text selected.
How could I achieve that?
Any help is very appreciate.
Regards,
Rimas M.

Best way to compare CGFloats
Hello, I am stuck with floats (doubles, to be precise) comparison. In part of my app, I am dealing with NSPoint components (x, y) comparison. On 32bit architecture NSPoint components are floats, and direct comparison ( float1 == float2 ) works fine. But on 64bit, they are doubles and '==' does not work due to precision. Lets take an example: C and D are NSPoints. Lets say C is (1.000444089209850063, whatever) and D is (1.00, whatever). If my code is: if (C.x == D.x) thenDoSomething; , then thenDoSomething is not called. Of course. But on my needs, float is more than enough for precision. So question is, what is the most efficient (performance side) and simplest (coding side) way to compare those bastards? At the moment I am thinking about: a) BOOL _floatsOrDoublesAreEqual = ( (float)C.x == (float)D.x); b) BOOL _floatsOrDoublesAreEqual = ( fabs(C.x - D.x) <= _epsilon ); , where _epsilon is something like 0.0001.

In my case I am interested in x's and y's comparison. Not points as themselves. But your suggestion gave me another question, which I have never thought about before - how NSEqualPoints, ...Rects etc works? I guess they *must* be safe to use, because NSPoint, NSRect etc relies on floats/doubles. Or they uses the same '==' and are TRUE only if points/rects are *really* equal?

Long delay of NSPopUpButton first click
Hello list, I am trying to do quite simple thing - add a popup with all fonts, available on system. Each item of menu, should be displayed in corresponding font. As an example could be all iWork apps. When you dealing with text, you have a popup with fonts, and each font name is displayed with "preview" of that font. I have tried to do that in very usual way: - iterating over available fonts - creating a NSMenuItem for each font, setting it up - setting menuItem's attributedTitle with corresponding NSFontAttributeName - adding menuItem to the popup. This works as expected, but after app launch, when I click on that popup for the first time, delay until menu is shown is unacceptable. Usually it takes a few seconds. All following times I click on the popup, the menu is displayed immediately. Until relaunch of the app.. Shark has not provided any useful information. So I am wondering - I have missed something, or should I use some "tricks" to avoid that delay? Any thoughts are very welcome.

Re: Long delay of NSPopUpButton first click
Drawing item titles into image and caching them for later use works nice. But I have noticed unacceptable side effect. Normally, when menu is displayed you can press any letter key, and menu will scroll to the first item, which title starts with that letter. In my case , NSMenuItems does not have titles and that does not work. Looking for workaround to maintain this functionality. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Catching actions of fonts "Typography" panel

That is way to abstract for my needs. Fair enough would be something like "font has changed". Or simply changeFont: for first responder. By getting that action I would be able to implement that changes for any of my views. Not only textview. Any thoughts?

Re: Catching actions of fonts "Typography" panel
Delegate methods could be used if there is an editable textview. But what if not? For other things we have "changeFont:, changeColor:, changeAttributes:".

Re: Catching actions of fonts "Typography" panel
You are absolutely right, Martin. That was I have thought at the beginning.
But it didn't worked. Now I have checked more deeply and looks like I have a
bug in my responders chain which prevents me from getting changeAttributes:.

Re: Text rendered in NSImage is fuzzy
Sorry for touching this old thread. I just want to be sure.

Re: Long delay of NSPopUpButton first click
Well.. that worked. Generally. But those images must have transparent background. And as I have discovered, when dealing with text drawing, that causes loose of sub-pixels antialiasing.

Unless I am missing something. Menu-item's background is changing when item is selected (blue one, by default). I am wondering how iWork apps was able to solve this. Their menu has full antialiasing and responds to keyboard for selecting items by first letter of title. This suggests AttrbutedString way. But it loads fast... Strange.

Getting notification about new font is available
Hello list, During weekend I was trying to figure out how to know when new font becomes available. The only method I was able to find is - (BOOL)fontManager:(id)* theFontManager* willIncludeFont:(NSString *)*fontName* of NSFontManager. But according to the documentation: * Important:* This delegate method is not called in Mac OS X versions 10.3 and later. So it does not work... (I have tried - just in case). For example: if I have a RTF file with "Noteworthy" family font (which is available by default on Lion, but not in SL), after opening it on SL (TextEdit) the font becomes visible in NSFontPanel for that app running session. I need to catch that moment to update my own fonts popup. Any thoughts are very appreciate.

Sandboxing + NSSavePanel's accessoryView
Hello, I am trying to enable sandboxing in my app, and I am dealing with a very strange behavior. I am not sure if this is a bug of Lion/Sandboxing or I have missed something in documentation. In save panel I am using a custom accessoryView which is set in "- (BOOL)prepareSavePanel:(NSSavePanel *)savePanel". I am setting setting accessory view to the real one only if savePanel's "- (BOOL)isExpanded" returns YES. Otherwise I am setting it to nil. To handle save panel's expansion I am using "- (void)panel:(id)sender willExpand:(BOOL)expanding" from NSOpenSavePanelDelegate. If expanding == YES, I am setting the real accessory view, and nil if expanding==NO. That worked very well on Snow Leopard. It even works well on Lion without sandboxing. But if sandboxing is enabled, it does not work. When save panel is displayed and I am trying to expand it, expands and collapses back. It is impossible to expand it. Log has showed, that I am getting - (void)panel:(id)sender willExpand:(BOOL)expanding with expanding==YES and the second one with expanding==NO. At the moment I have no clue what is going on. Any thoughts about this behavior would be very appreciate.

Drawing FULL NSAttributedString
Hi folks, Last few days I am trying to solve very strange puzzle - how to draw FULL attributed string. Short story: I have a NSTextStorage object, which holds my formatted string information. I am editing it via NSTextView (NSLayoutManager + NSTextContainer + my NSTextStorage) mechanism. That works great until I am dealing with drawing. To find out rect, which will be required to fit my text, I am using - (NSRect)usedRectForTextContainer:(NSTextContainer *)aTextContainer of NSLayoutManager. To draw actual content I am using drawBackgroundForGlyphRange:(NSRange)glyphsToShow atPoint:(NSPoint)origin and drawGlyphsForGlyphRange:(NSRange)glyphsToShow atPoint:(NSPoint)origin from the same NSLayoutManager. And that works great for 90% of time. But I need 100%. Problem: Actually I am dealing with two drawing problems: 1. When my attributed string (NSTextStorage) has a shadow, made by using Fonts panel, it is NOT INCLUDED when trying to find out used rect by calling [myLayoutManager usedRectForTextContainer:myTextContainer]. Never. The situation can be easily demonstrated with TextEdit: https://www.dropbox.com/s/vt21zpq46xl0gb5/Text-with-cropped-shadow.png . The same I am getting in my app. But I need a shadow, therefor I have set it. To draw it correctly, I need a bounding (used) rect, which counts in a shadow attribute. Is it possible at all using cocoa text system? 2. With some fonts (for example Eccentric Std, Palemonas, some others which i can't remember right now) the [myLayoutManager usedRectForTextContainer:myTextContainer] returns rect which does not covers WHOLE text. Sometimes diacritic symbols of the very top line are missing (https://www.dropbox.com/s/dpjjugzxcnp771r/Missing-diacrytic-symbol.png <- both letters are the same "Alt + e + e = é" combination), sometimes the first left symbol is cropped (https://www.dropbox.com/s/33mfgoqwbgwcvg1/Cropped-left-side-1.png, https://www.dropbox.com/s/kbgfdzuhcr1svht/Cropped-left-side-2.png, https://www.dropbox.com/s/ntxgufl8e562uep/Cropped-left-side-3.png). Question is the same - how to get rect, which would fit my whole text. Any help is very appreciate. p.s. don't hesitate to ask for an additional information. I could even make a small sample app if required. Regards, Rimas M. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Drawing FULL NSAttributedString
Hello Aki, Thank you for reply. Looks like I will need to learn lots of new things, because fonts metrics are unknown world for me. I have played a bit with "rect of glyph" from NSFont and NSLayoutManager. Some useful information can be found. But lots of unclear things are mostly with baselines and offsets of them.. For example NSFont's boundingRectForGlyph: returns rect, which looks like gonna fit whole glyph, but currently I have no idea how to calculate its position (x and y) in the line of TextView/LayoutManager.

Vertical alignment in NSTextView
Hello, I continue my fight with cocoa text system :)) At the moment I am loosing.. Now I am trying to implement vertical text alignment in NSTextView. If I would need only drawing, would be quite easy. But I need to maintain an editing capability. The thing I am talking about is very similar (or even the same) to the text writing inside shape (rectangle) using Keynote: insert rectangle shape, double click it ant write some text. Using inspector (Text tab) you can choose between top, middle and bottom vertical alignment. I am almost sure, that I need to subclass and overwrite some stuff from either NSLayoutManager or NSATSTypesetter. Just not sure which exact... Any thoughts?

Re: Vertical alignment in NSTextView
Hello Andrew, Nope - that will not going to work, because container inset is expressed as a size and inset is set equally from both sizes: inset.width for left and right "margins", inset.height for top and bottom "margins".

Re: NSTextView and NSTextContainer size & clipping area
As far as I remember, text container inset sets "margins" from both sides:
left and right and/or top and bottom. If text container position is
important according to the text view, this will not work.

Yes, I have followed your suggestion and I am using one of them to access iDisk.

I am talking about things stored at /Web/Sites/_gallery/ xx/ I have tried to mimic structure created by iPhoto, but that does not work. There must be something that I am missing.

Transparent IKImageBrowserView
Hello, As far as I know, it is still impossible to have transparent background of IKImageBrowserView? I am writing to be 100% sure for that. Maybe I have missed something? All my attempts to create transparent IKImageBrowserView failed. I have tried: * (1) setting background color for IKImageBrowserView as itself using IKImageBrowserBackgroundColorKey. That works well until color alpha is equal to 1.0. Bellow that color is ignored (color does not change) or background is changed back to default white. Or... looks like given color is composited on a white background. * setting CALayer as IKImageBrowserView's backgroundLayer: ** (2) using property backgroundColor of CALayer. No background transparency, scrolling ghosts, misc garbages during start-up - some parts of menubar, other windows are visible for a few moments after program launch. ** using custom drawing ( - (void)drawInContext:(CGContextRef)context ) in CALayer subclass: *** (3) drawing transparent image to fill background. No transparency for IKImageBrowserView, some strange ghosts while scrolling. *** (4) filling background with transparent color (alpha < 1.0). Behaves close to previous variant. "Size" of ghosts depends on alpha value. On 3 and 4, flushing context or telling it to clear visible rect makes no sense.

Re: Transparent IKImageBrowserView
My fault. I was sure, that I have checked everything and nothing. I have made a new empty Xcode project and that worked. Finally I have found strange bug in my NSScrollView subclass. Fixed it and looks like everything is OK now. Thank you. Best Regards, Rimas M.

Rotated and scaled CALayer
Hello list, I do not have a lot of practice with Core Animation, maybe that is the reason. I have a real annoying problem. All I want to do is: 1. Create CALayer 2. Set CGImage for its content 3. Depending on situation rotate and zoom in that layer (or its content) Looks like everything works, but I am getting "rotated" pixels (http://dl.dropbox.com/u/2030721/ForAppleList/Rotated%20Pixels.png). That is not what I want. I would like to get rotated content of image with "straight" pixels. I was trying to play with layer transform property, with layer delegate "- (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx" and by using CGContextRotateCTM etc. I have even tried to use layer and sublayer to split transforms (one layer scales, and other rotates) but result is always the same. Is there any way to achieve result I want? Currently the only way I know is: a) to rotate an image by drawing it to the bitmap context b) create new rotated CGImage from it c) and then draw it for scaling. But this way is quite slow. Is there a better one? Any help is very appreciate. Best Regards, Rimas M. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Rotated and scaled CALayer
Hello Andreas, Thank you for detailed explanation. However, I am not able to do what I want. Almost. I have discovered, that if I use only CA layers transformations (via setTransform:), I am getting the same rotated pixels when zooming in. The only way, which does what I want is: a) use core image filter to rotate layer (simple CIAffineTransform) b) use second CI filter to tell renderer to use nearest interpolation instead of linear. c) use CA transformation to scale layer Filter mentioned in b) does nothing. It only sets kCISamplerFilterNearest for kCISamplerFilterMode of the input sampler. And for c) I am using CATransform3DMakeScale. Result is OK - when zooming in pixels remains unrotated. But new problem occurs - when scrolling (even slowly) zoomed in layer, the "pixels" flickers. And that causes filter of b). If I am not using it, o its kCISamplerFilterMode setting to the kCISamplerFilterLinear, flickering is gone. But zoomed pixels becomes rotated. Rotated pixels: http://dl.dropbox.com/u/2030721/ForAppleList/Rotated%20Pixels.png Expected result: http://dl.dropbox.com/u/2030721/ForAppleList/Non-rotated_pixels_when_zooming_in.png Best Regards, Rimas M. p.s.

Re: Rotated and scaled CALayer
Hello Vincent, > Did you had a look at the vImage framework? > > Vincent No I hadn't. I not quite sure which action (and how) I could use in addition with Core Animation. I need (near) real-time drawing for scaling and rotating. So dealing with pixels data for every update is quite expensive. Unless I am missing something?

Shortcut handling in different keyboard layouts
Hello, I have a question about how properly keyboard shortcuts should be handled. For example "pressing key X performs action W". How to ensure that this will work with all keyboard layouts (Cyrillic etc)? Currently I am checking key down event characters, but that is a wrong way, because when layout is changed to Cyrillic that does not work. I thought that would be great to use keyCode to check which action should be performed. But then I remembered German keyboard layout - it has Z and Y mixed. Keyboard button, which has label "Z" in US layout produces keyCode 6, and button with label "Y" produces 16. In German layout codes are the same, but labels swapped. Take iTunes as example. With US layout enabled, pressing Cmd+Y calls Preferences. Meanwhile to do the same in German layout you need to press also Cmd+Y, but "Y" button is not the same as in US and produces different code. I am wondering - how to check incoming key down events to achieve that functionality. I am sure, that checking characters is wrong way. Better would be to check keyCodes, but not perfect. Is there a third way in Cocoa? Help would be very appreciate.

Do you mean [[theEvent charactersIgnoringModifiers] characterAtIndex:0] (which returns unichar) or something different?

While keyboard layout is US for example, pressing "P" (lowercase, without shift or any other modifiers) gives code 112 (ASCII lowercase 'p', ASCII and Unicode 0-255 matches). Meanwhile after switching keyboard layout to RU (Cyrillic), pressing the same key produces symbol "з" (I am sure on www this symbol will not be displayed) with unichar code 1079. And that is the problem - what I need to do to ensure that pressing "p" in US and "RU" keyboard layouts will do the same action in my app. Regards, RImas M. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I have an idea: Check if input character has code 0-255 (ASCII). If yes - perform matching by symbol or its code. Otherwise (Unicode symbol, like Cyrillic) perform matching by keyCode.

I am not sure which way is best for users. The best example for I am talking about is Photoshop tools switching via keyboard. I doubt it uses (or maybe?) Cyrillic characters mapping. Because if you want to switch to Pencil tool, you need to press "P" labeled keyboard button in US layout. Even more, you must press the same button on RU layout. But that button produces "з". I am not talking about command-key -> actions. I want to implement key -> action in the correct way. I am quite sure, that such company as Adobe and long-time project as Photoshop would do that in right way. Maybe I am wrong. For this reason I am writing here.
