How do I get the new toolbar item style of OSX Yosemite?
I created a standard toolbar, but the buttons don't have that button-like look. Do I need to drag actual buttons to the toolbar to get this look?
What I have:
What I want (that round bezel and white background):
There are two types of items in toolbars, image items and view items. It looks like you have an image item. You seem to want a view item where the view is an NSButton configured as a round textured button. So, yes, you should drag actual buttons to the toolbar.
I would not attempt to control the button background. You should use the button as-is to get the default system appearance. Apple recommends using a PDF template image (all black with the alpha channel used to make the image). The button itself would not have a title/label. Rather that would be on the containing toolbar item.
It looks like you may have applied an internal blue "glow" or highlight to your image. Generally, you should not do that. Let the frameworks apply appropriate effects to the template image automatically based on the button state and shows-state-by mode.

Works just fine for my Cocoa app under Yosemite -
are you actually setting the template property for your icon images..?
From the NSImage docs:
The 'template' property is metadata that allows clients to be smarter
about image processing. An image should be marked as a template if it
is basic glpyh-like black and white art that is intended to be
processed into derived images for use on screen.

My goal is to view the content of the bottom page from the top of the other content page. In order to accomplish this, I used PushModalAsync to navigate and set the BackgroundColor property of the navigation page to Transparent. I can view the content on the bottom page on Android. However on the iOS platform, a black color is always displayed and I am unable to read the content of the bottom page. Why is the background color always black even when it is set to be transparent in PushModalAsync?
Note: The iOS platform displays a white screen when I change the navigation to PushAsync.
Expected Behavior:
Background color should not be black and it should be transparent when navigating using PushModalAsync
Actual Behavior:
Background color is always black even when the content page background color is set as transparent when navigating using PushModalAsync

If you want to do EXACTLY like that, it is not possible (it will require so much work that you can't expect someone to provide you the solution here).
On iOS that control (ViewController) is drawn that way in that presentation mode. So as long as you use that control and that mode it will work that way irrelevant if you use Xamarin or something else. As ViewControllers are most basic controls it is not realistic to replace them with something else. But you can replace presentation mode. In Xamarin.Forms you can do that this way:
<ContentPage ...
xmlns:ios="clr-namespace:Xamarin.Forms.PlatformConfiguration.iOSSpecific;assembly=Xamarin.Forms.Core"
ios:Page.ModalPresentationStyle="FormSheet">
...
</ContentPage>
This will result in somewhat different visual presentation but that is the only way to have one ViewController drawn over another without going into some deep customization that would require tons of code, especially on Xamarin.Forms.
You can also try some other values, but the default value will not work.
In iOS, the hierarchy is managed by the view controller. Each page has a separate view controller. A page consists of a window, a root view, and a subview. You cannot see the layout of the previous page by setting the background color to be transparent.

I am working on OSX 10.10
I am facing a strange problem of sub view colors getting inverted for HUD Panel.
For example the button when set to default button looks right in Xib file but when executed the look and feel of button is modified by the HUD panel.
I am having a HUD Panel in my Xib file as follows
But when executed the button looses its default button status. It looks as follows
How do I maintain the look and feel of the button after execution. User is not able to judge which action will be the default action due to this look and feel
Try
_defaultButton.appearance = [NSAppearance appearanceNamed:NSAppearanceNameAqua];
Interface Builder follows a set of rules but these rules are not context-dependent. The context I'm talking about is "being displayed in a HUD Panel".
The rule applied in this case is "draw a blueish button in Interface Builder if the button is a default button" even if it's not always what happens (cf. what you're seeing in your second screenshot).
I don't know since which OS X version it's working like that, but now controls in HUD Panels are displayed with a different style (which does not have a special color for default button).
You can confirm this Interface Builder comportment by adding a simple NSTextField in your HUD Panel, it'll draw with a white background in Interface Builder but it will have a black background when running with a gray focus ring.
Interface Builder:
OS X 10.10:
I've never found a way to disable this special styling for controls in HUD Panel but several workarounds (the default button is still working correctly even if not having a special color).
The special styling only occurs when your HUD Panel have a title bar.
self.panel.styleMask = (NSHUDWindowMask | NSTitledWindowMask | NSUtilityWindowMask | NSNonactivatingPanelMask);
If you remove the title bar, it'll display without any special styling:
self.panel.styleMask = (NSHUDWindowMask | NSUtilityWindowMask | NSNonactivatingPanelMask);
At this point, you can implement and draw your own title bar in the panel and mimic the default one. I don't really like this approach because first it's a lot of work for a simple button and the custom styling of controls make them prettier and more easy to read in a HUD Panel.
Another solution was the 'VLC' way. They use HUD Panels but their controls don't have any special styling. They're using BGHUDAppKit which was released when Apple provided HUD Panel without any special controls to go with it. They use it to force the bluish style instead of the greyish one which are now used by default in HUD Panels.
I didn't really like this approach too, I didn't want to add a library for a simple button, library not updated since 2011.
What I end up doing was drawing a custom button (with a simple subclass) for default buttons in a HUD Panel. This solution is quick and allow you to choose the color you want for default button in a HUD Panel (blueish may not be the best for a HUD Panel, your call).
I am new in MAC OS X development, I have to align text centre in nsMenuItem but I not find any particular solution. I checked on google but not find any tutorial.
Find some tutorial but not exactly same, in these tutorial we take a NSView in nsMenuItem and then Insert subview in NSVIEW to accomplish it centre align.
Is there is any better solution? Please provide me link if possible.
Edit : I attached screen shot, but this is not working for me.
Thanks
You can set the Attributed String of the menu item, which does allow you to center the text, as well as change the font, color and size of the text as well.
I do not know which version of Xcode/OSX you are using, but under Xcode 5.0.2 you can use the built-in interface builder to edit the attributed strings of menu items.
Click the MainMenu.xib entry, then click the menu you want to edit to open it, then click the menu entry. On the right side of the window there should be some options, if not click the right most square in the group of 3 at the top right of the Xcode window 1.
Once you have the right panel open click the Attributes Inspector icon [2] (4th from the left, looks like a slider type icon). At the bottom of the list of attributes you will see an entry for "Attrib. Title" [3].
That is where you can set a custom font, color and alignment for your menu item.
If you need more control then that provides, you can also embed custom NSViews into your menus which gives you complete control over how the menu will look.
I'm wondering if in IOS is possible to customize segmented control like the attached image. I have tried to change buttons image, but the segmented control container is still visible under the customized buttons. I observed that the segmented buttons title disappears if you add button image. Custom button images must include title?
Many thanks
Just roll your own. Make three UIButtons with two images for each state and write logic to allow only one of them to be selected.
I'm build a Mac application in the style of the Lion Mail.app. As part of this I'm attempting to create a simular toolbar to the one in the Mail.app but I can't seem to get the image in my toolbar button centered vertically.
Looking at the Mail.app toolbar I see a nice series of buttons with centered icons:
but when I go interface builder I can't seem to recreate the same button. What I get is:
What I've tried doing is, in Interface Builder:
Create a new window
Add a NSToolbar to that window
Add an NSButton to the toolbar with Style - 'Push', Image - 'Envelope', Position - 'NSImageOnly', Scaling - 'Proportionally Down'
As you can see the icon is clearly not centered vertically on the button like those in the Mail.app toolbar.
Anybody have any ideas???
At the moment I'm using XCode 4.2 and laying out this button with Interface Builder. I'm trying to build the toolbar button by ONLY adding the image to the button and not painting the button for each item, ie drawing the border and icon.
Any help would be greatly appreciated as this has been driving me a little nuts.
Thanks in advance - AYAL
Turns out the answer to this problem was much simpler then I had expected. After a lot of teeth gnashing, hair pulling, and twiddling pixels I came across the solution.
Instead of using a 'Push' button I simply had to switch to a 'Round Textured' button. Once I did that any image I added to the button was nicely centered. Next I just had to manually scale my image to look right.
The recipe then for a Mail.app Toolbar is as follows:
Add a button to your Toolbar
Set the button style to 'Rounded Textured'
Set the image of the button
Set the position to 'NSImageOnly'
Set the button size to 40 x 25 as well as the min and max sizes of the ToolbarItem
The result is a toolbar that can look very simular to the Mail.app toolbar.
Thanks All - AYAL
One way to do it is to have your image actually be the button i.e. take up all of the button's canvas. You will have to use the button's setBordered: method so the button's border is not drawn.
you could make the button image in something like gimp or photoshop then use that as the background or image for the button.
i feel like your going to say "this is what im doing". and maybe you made the little mail icon but i mean for you to make the whole button, outline and everything, then use that for the button image. make sense?
like here, just use this as the background
