Re: NSTokenField token color/control

[Brandon Walkin]

I wrote some code a while back to customize the appearance of a token  
field. Feel free to use it. It does use some private API, though, so  
beware.

Re: NSScroller width

[Brandon Walkin]

Use +scrollerWidth and +scrollerWidthForControlSize. Here's a custom  
scroller subclass from BWToolkit which might help you out: http://bitbucket.org/bwalkin/bwtoolkit/src/tip/BWTransparentScroller.m

Hi there,

I've googled a lot before post this question but I'm stucked.

I'm trying to subclassing NSScroller to change the aqua look and,  
most important, to change the width of the vertical scroll bar.


My subclass is:

- (void)drawRect:(NSRect)rect
{
  [self drawKnobSlot];
  [self drawKnob];
}

- (void)drawKnob
{
  NSRect rect = [self rectForPart:NSScrollerKnob];
  [[NSColor darkGrayColor] set];
  [NSBezierPath fillRect:rect];
}

- (void)drawKnobSlot
{
  NSRect rect = [self rectForPart:NSScrollerKnobSlot];
  [[NSColor grayColor] set];
  [NSBezierPath strokeRect:rect];
}

It works and change the look as I want but not the width. I tried to  
set rect width but is not the right way because the rect goes beyond  
the scrollview.


Any help is appreciated.

Thanks,
Max

Re: Applying color to template images

NSImage *copiedImage = [self copy];

Changing NSSliderCell's knob thickness

[Brandon Walkin]

I'm trying to make a vertical slider with a knob that's 1 pt tall. I  
can't quite figure out how to do this without rewriting NSSliderCell.


Overriding -knobThickness and returning a particular thickness doesn't  
seem to have any effect on the thickness of the knob. The - 
setKnobThickness: method is deprecated, but it too seems to have no  
effect on the knob size.


I could fake it by drawing a 1 pt tall line in the center of the large  
knob rect I'm provided and drawing the slider track with an inset on  
both sides so the 1 pt tall knob can reach both ends of the slider.  
The issue with that is when the area on the track near the knob is  
clicked, the knob won't move to that position. And when that area on  
the track is dragged, the knob moves as though it's being dragged.  
Since NSSliderCell thinks the knob is thicker, it thinks the click is  
on the knob instead of the track.


I've made a basic sample app that you can play with: 
http://www.box.net/shared/ylqm2uck5o

Any help would be appreciated. Thanks.

I tried imageNamed, but it does not find an image. I tried to search

Hi all,

I've just released version 1.2 of BWToolkit with three new additions:  
a gradient box with customizable border and inset lines, a styled text  
field that lets you apply a gradient and a shadow to text, and a  
hyperlink button to link text or images to URLs. I've also added Snow  
Leopard support and various fixes and improvements.


For those who haven't heard of BWToolkit, it's a BSD licensed plugin  
for Interface Builder that contains commonly used UI elements and  
other objects designed to simplify Mac development.

This method was introduced in 10.5. If you require Tiger

Alternately, you can use BWInsetTextField which is part of the

[ANN] BWToolkit 1.1 IB Plugin: Codeless Split Views

[Brandon Walkin]

Hi all,

I've just released a new version of my IB plugin with a split view  
that requires no programming for common split view functionality.  
Right within Interface Builder, you can specify which subviews should  
resize with the split view, set min and max sizes on subviews, mark a  
subview as "collapsible", and hook a button up to an action on the  
split view which will collapse or expand the collapsible subview with  
Core Animation.


Watch a screencast of the split view in action and read more about it  
here: http://www.brandonwalkin.com/blog/2009/02/24/bwtoolkit-11-codeless-split-views/


If you've never heard of BWToolkit, this webpage outlines all the  
features: http://brandonwalkin.com/bwtoolkit

Use a cell to draw your text and call -setBackgroundStyle: on it with

method is Leopard-only.

Re: subpixel rendering vs. layer backed views

[Brandon Walkin]

There are a couple tricks you can use to retain subpixel antialiasing.  
If you're giving the view a layer so you can animate it occasionally,  
try giving it a layer just before you tell it to animate and removing  
the layer once the animation is complete. For quick alpha or origin  
changes, the user won't notice the temporary lack of subpixel rendering.


If the view sits on a constant background, then you can retain  
subpixel antialiasing while the view is layer backed, provided that it  
draws a background. Some views (like text fields, for instance) can be  
configured to draw a background color in Interface Builder. Other  
views (like the check box you have in your sample project) need to be  
subclassed to draw a background. Just override -drawRect:, draw your  
background, and call super.  Keep in mind, the background you draw  
doesn't need to be a flat color. It can be a gradient or some wacky  
pattern, as long as it's opaque.


-Brandon

Is it the case that I can have a layer backed view (and thus nice

I feel like I'm missing something but when I put a check box in a  
layer backed view, it looks terrible. It's poorly antialiased and  
there is no subpixel rendering.

gradient rect by a pixel to leave space for it so you can draw it at  
some other point in drawRect:.


Here's the relevant code from BWToolkit (http://brandonwalkin.com/bwtoolkit 
):


static NSColor *topColor, *middleTopColor, *middleBottomColor,  
*bottomColor;

static NSGradient *gradient;

+ (void)initialize;
{
topColor = [[NSColor colorWithCalibratedWhite:(253.0f / 255.0f)  
alpha:1] retain];
middleTopColor = [[NSColor colorWithCalibratedWhite:(242.0f /  
255.0f) alpha:1] retain];
middleBottomColor = [[NSColor colorWithCalibratedWhite:(230.0f /  
255.0f) alpha:1] retain];
bottomColor	= [[NSColor colorWithCalibratedWhite:(230.0f /  
255.0f) alpha:1] retain];


gradient = [[NSGradient alloc] initWithColorsAndLocations:
   topColor, (CGFloat)0.0,
   middleTopColor, (CGFloat)0.45454,
   middleBottomColor, (CGFloat)0.45454,
   bottomColor, (CGFloat)1.0,
   nil];
}

- (void)drawRect:(NSRect)rect
{   
rect = self.bounds;

NSRect gradientRect =  
NSMakeRect 
(rect.origin.x,rect.origin.y,rect.size.width,rect.size.height - 1);

[gradient drawInRect:gradientRect angle:270];
}

These are just debugger errors.  This is most like due to those

stripped.  It should not affect debugging of your own application.


I did some googling and found that people used a tool to use  
@executable_path rather than @loader_path but I also read that  
those values should be the exact same so changing them is not the  
optimal change to make.


For an application, they resolve to the same thing.

Does anyone have any idea where I can see / set these values?  I  
have checked my Xcode Project Build settings, the framework build  
settings, etc. and cannot find them.


They are set in the frameworks project, not yours.  So if you're  
linking to pre-built versions of Sparkle and BWToolkit, there are no  
settings in your app that affect this.


In general, @loader_path is preferred over @executable_path, as it  
allows embedded frameworks to work in both an executable and a  
bundle, plugin, or sub-framework.  The only downside is that  
@loader_path requires 10.4 or newer.  If you're on 10.5 or newer,  
@rpath is even better than @loader_path.

I'm the developer of BWToolkit. Some users have run into this problem

Re: 2-pixel borders in NSSplitView - I want 1 pixel.

[Brandon Walkin]

NSSplitView's thin style produces 1 pt thick dividers. You can verify  
this by asking the split view for it's -dividerThickness. What's  
likely happening in your document is that one of your subviews has  
it's border style set to something other than "none" in IB. Your  
divider would appear to be 2 pixels thick, but one pixel would be the  
divider and the other would be the subview's border.


To change the color, you can use BWSplitView (which it appears you  
already have loaded in IB). It's a subclass of NSSplitView which, at  
the moment, only adds one feature which is being able to set the color  
for thin dividers in the IB inspector.


The two common divider colors are 64,64,64 and 165,165,165. Please  
don't use black. :)

Not so good. When creating or opening a document, there's more to do  
than just creating the NSDocument instance.  
openUntitledDocumentAndDisplay:error: is the way to go.


By itself this wouldn't pop up a document because of the overridden  
applicationShouldOpenUntitledFile: method


No, that had nothing to do with it. By creating the NSDocument  
instance directly, you simply weren't getting the document window  
shown.



So I added:

[newDoc makeWindowControllers];  and the method mentioned below.

Reading your notes carefully though it looks like I maybe should be  
using openUntitledDocumentAndDisplay:error instead of the  
makeWindowController thing that got my document to popup perhaps  
only because I added the showWindow:self to the end of that method.


Exactly.

And you are probably right that I am getting two instantiations,  
but only "seeing" one.


I will test your suggestion first, though It might take me a few  
because the template doesn't generate a NSDocumentController, only  
the NSPersistentDocument class itself so I first have to figure out  
how to add the Controller to my AppController class and stuff  
without breaking everything,  I should be able to  get  
openUntitledDocumentAndDisplay:error to work (I bet it does, so  
here is a pre thank you!!!),


No need to stress! NSDocumentController is a singleton object that  
every AppKit application gets for free. So instead of:


  MyDocument *newDoc = [[MyDocument alloc] init];

just write this:

  NSError *error;
  MyDocument *newDoc = [[NSDocumentController  
sharedDocumentController] openUntitledDocumentAndDisplay: YES error:  
&error];

  if (!newDoc)
  ... // report the problem described in 'error'

... I pulled out the extra call to makeWindowControllers and  
traced, When the document gets create via the New menu item the  
makeWindowControllers gets called automatically like you described,  
but just instantiating the document with MyDocument *newDoc =  
[[MyDocument alloc] init]; doesn't call makeWindowControllers.   
Perhaps that is what the NSDocumentController is supposed to do for  
me?


Yup. It also causes the document to appear on the Window menu for  
you, and populates the Open Recent menu.

You can't set one in IB. The workaround is to declare outlets in  
your File's Owner object to each of the toolbar items you need to  
refer to, and then use the outlets directly (or get the IB-assigned  
identifier via the outlet, if that's what you need). That will  
probably feel a bit hokey, but perhaps a future version of IB will  
have a more elegant implementation for this.




Replying a bit late here but I should point out that since version  
1.0.2 of the BWToolkit IB plugin, it has supported the ability to  
specify an toolbar item's identifier in the inspector.

Re: Newbie. Creating SubViews that aren't associated with NSWindow, or NSPanel?

[Brandon Walkin]

The NSPanels are unnecessary middle men in your case. Rather than  
using an NSPanel in order to access its contentView, instead create a  
new standalone view object in IB by dragging in a custom view from the  
library to the document window (not the canvas). Then double click the  
view's icon in the document window, and the view will open up in a  
window. You can then go ahead and lay out its contents, just as you  
would with a NSPanel's contentView.

outlets from, for example, File's Owner to these views to reference
them later in the code."

Is there a way to visually see in interface builder the view, without
it being in a window/panel?

Thanks a lot for the feedback.

Here's kind of what I was thinking..

option 1. Create multiple NSWindows or NSPanels, for view1,view2. Use
the contentView property of those windows to attach to my main window
when you've clicked a toolbar button.
option 2. Use separate nibs for the views, each nib would be an
NSPanel. Then the main bundle loads those nibs in, attaches it's
contentView to the main bundle's main view.

Is this the right direction? I'd really appreciate some feedback.

Thanks all

Re: Fixed width of left pane in NSSplitView

[Brandon Walkin]

Feel free to use the -splitView:resizeSubviewsWithOldSize: delegate  
method implementation from this class:

http://www.bitbucket.org/bwalkin/bwtoolkit/src/tip/BWAnchoredButtonBar.m

It keeps all views except the right most view at a constant width when  
the window is resized.


To incorporate this in your app, just copy the method into a class of  
yours and set it as the split view's delegate using the -setDelegate:  
method. You can read more about delegation in the docs: http://developer.apple.com/DOCUMENTATION/Cocoa/Conceptual/CocoaFundamentals/CommunicatingWithObjects/chapter_6_section_4.html


Cheers,
Brandon

No. Just wire up a different object as the delegate for your split

Re: Creating a Bottom Bar on NSWindow

[Brandon Walkin]

You can use my BWToolkit plugin for Interface Builder to add a bottom  
bar. The advantage to using the plugin rather than doing it  
programmatically (as Andre suggested) is that you'll be able to see  
the bottom bar in IB which makes it easy to position UI elements on or  
above it.


Here's a link:

I could not find any control or info on how to do this, but I noticed
that if I set the Appearance : Texture attribute to true in Interface
Builder (for the window), I seemed to get a bottom bar.

You can see a screenshot here:

My question is:

Is this the correct way to create the bottom bar?

Is there any way to style the window so it look more like itunes
(itunes has a lighter grey).

Thanks for any input...

I've been playing with this too, and I used -setSelectedIndex:  
because that is in your header and -switchToItemAtIndex:animate: is  
marked as private. I also tried using NSToolbar's - 
setSelectedItemIdentifier:, however that causes the toolbar icon to  
change but not the view, so you may want to override that.


1) add:
- (void)setSelectedItemIdentifier:(NSString *)itemIdentifier
{
  selectedIndex = [itemIdentifiers indexOfObject:itemIdentifier];
  [self switchToItemAtIndex:[self  
toolbarIndexFromSelectableIndex:selectedIndex] animate:YES];

}

2) change line 284 in -selectItemAtIndex: to call supers  
implementation:

[super setSelectedItemIdentifier:identifier];

Using the label to change the toolbar selection is not a good idea  
because the labels may be localized and then they won't match. And  
using the index only works for toolbars that can't be modified. You  
could create a custom NSToolbarItem class in IB and add the  
identifier to the IB inspector, that way developers can set custom  
identifiers in IB like they can when creating the toolbar items in  
code.


One more thing, any of the headers (like BWSelectableToolbar.h) that  
users of your framework may need to use your classes, should be  
marked as public so that the headers are exported with the framework  
and then we can include them like:

#import "BWToolkitFramework/BWSelectableToolbar.h"


--Nathan



Thanks for the suggestions. I'll implement them for the next release.

Just a note: I'm tracking issues on Bitbucket so if you have any other  
bugs or feature enhancements, please post them there. http://www.bitbucket.org/bwalkin/bwtoolkit/issues/

Brandon

[ANN] BWToolkit - Plugin for IB 3

[Brandon Walkin]

Hi all,

BWToolkit is a BSD licensed plugin for Interface Builder 3 that  
contains commonly used UI elements and other useful objects. These  
include a suite of transparent (HUD) controls, a selectable toolbar  
for "no code" preferences windows and tabbed sheets, button bars,  
textured bottom bars, a textured slider, a gradient token field, and  
much more.


You can read about it in more detail, watch screencasts, and download  
the plugin (along with the source) on my blog:

Re: Static text over an image

I've seen it happen a few times where views will be layered in the  
reverse order that they're set to in IB. Try moving the label behind  
the image and see if that gives you the desired result.

Brandon

Re: Changing NSTextFieldCells' editing appearance?

The black color you're seeing when editing is the -backgroundColor of

appropriate color.

Re: How do I get those 1 pixel black lines into my app window?

[Brandon Walkin]

Use a non-textured window instead of a textured one. You'll get a  
black line beneath the titlebar (or toolbar). To get a bottom bar with  
a divider line, call this method on your window:


- (void)setContentBorderThickness:(CGFloat)borderThickness forEdge: 
(NSRectEdge)edge


Set the thickness to 34 for a large bar, or 24 for a small one. Edge  
should be NSMinYEdge.


Cheers,
Brandon

This looks better than stock, which of course is why everybody and

people using horizontal line NSBox objects to create these?  That
seems like a kludge.  They also make for Illegal Geometry complaints

Re: NSTextFieldCell subclass template image inversion

[Brandon Walkin]

You can make a template image white by telling its cell:

[cell setBackgroundStyle:NSBackgroundStyleDark]

Cheers,

On 26-Jun-08, at 4:18 PM, [EMAIL PROTECTED] wrote:


Hello list

My NSTextFieldCell subclass is based on ImageAndTextCell.m from the  
SourceView sample.

This displays text and images in a single cell.

My difficult is in getting system media template images to invert  
when the cell is highlighted.

The documentation for NSImage - setTemplate states:

You can mark an image as a “template image” to notify clients who  
care that the image contains only black and clear content.


Yes, I detect that an image is a template, but how do I initiate  
"caring".


My feeble attempts at getting my client to care have firstly been to  
try and invert the NSImageRep of the template, but this fails as the  
image rep is the undocumented NSCoreUIImageRep and not a  
NSBitmapImageRep.


My second attempt was along the following lines:

[cell setHighlighted:YES];
[cell setState:NSOnState];
NSImage *image = [cell preparedImage];

A modified - duller - image is returned, but not an inverted one.
I think that this is more along the right track. But something's  
missing (brains probably).


Any enlightenment would be welcome.

Jonathan

Re: Constraining a NSSlider to Certain Values

I have managed to get my slider working the way I want it to by
overriding mousedown and mousedragged, however there is still one
small detail. I cant see how to make the slider knob show its
'pushed' image while the slider is being dragged. Does anyone know
how to do this?

thanks!

I'm not sure but maybe -[NSCell setHighlighted:] will help you.
If it does not work, have a look at -[NSCell setState:]

That's probably one of this two properties that control the cell
apparence.



Sadly both of those don't appear to do the job. Oh well.

regards,

Peter


To show the pressed image, implement -startTrackingAt:inView: and
-stopTracking:at:inView:mouseIsUp in your cell. All you need to do
in these methods is set a BOOL and then call super. Then in the
method where you draw your knob, check the BOOL and draw the pressed
or normal image accordingly.
