I am having trouble making text fields look acceptable when using different typefaces.
See this screenshot taken from a test app I made to demonstrate the problem. It consists of a single XIB, with no code in the delegate or anywhere else. This is on OSX Mavericks with Xcode 5.1.1 but I haven't tried on other versions.
The default system font looks fine in the top text field, as you'd expect. Compare this to the one below: same exact size and shape, all I did differently was change the typeface in Interface Builder. Text is pushed downwards, and descending letters (lowercase pqjg) are clipped. The Menlo example below is also pushed downwards, though not quite as badly.
How do I fix this?
A quick test shows Lucida Grande and Helvetica require 17 pixels, and Menlo requires 19 pixels:
Note that this excludes the border and shadows, so you need your text view to be significantly larger than that to guarantee it will fit.
Interface Builder has been specifically designed for Lucida Grande, it knows it can get away with being too small because that font doesn't use all the space it has available. Doesn't work well with other fonts.
You can resolve this a couple of different ways:
• Enable "Uses Single Line Mode" on the Text Field Panel. When I first
encountered this issue it wasn't obvious that this would automatically
align the text vertically within an NSTextField.
or...
• Simply adjust the size of the NSTextField using the adjustment boxes
that appear after you click on it. You can also adjust them through
the "Control" properties.

I know how to programmatically change QFont, either directly or via Style.
Problem is: is there some way to say "use the largest Font fitting into given space" (and change it when window is manually resized)?
Or should I override resizeEvent() for affected QWidget(s), recompute font, apply, etc, etc?
I have some difficult time in creating iOS screen to match with visual design provided by design team.
The design team has provided the spacing info for each screen which shows how much space each text needs to be apart from other UI element on the screen. This is attached for your reference. You can see here that the two text labels "Activate Your Account" and "A Verification link...." are placed apart by 25px.
The same thing I am trying to achieve in the storyboard. I am attaching the storyboard screen snapshot for reference.
From this you can see that I cannot keep exactly 25px b/w the two text labels because for the following issue
The text font is custom font and I cannot load the same in storyboard. I have added the font file in the project, but when I try to open it in storyboard for UILabel, it doesn't list out. I am not sure why xcode doesn't show up. This makes me hard to resize the label's frame. If I try to decrease the empty space in the label (upper and lower part of the text), this will make label height less, but when I set the font programmatically, it doesn't fit in this small space.
When I try to increase the height of the label, the text inside the label starts displaying at the center leaving space at the top and bottom of the label frame.
So I want to know how to solve this problem. If anyone had this issues and sorted out, please let me know how to fix this.
Many Thanks
Your designers aren't speccing their designs correctly :) Show them how iOS renders text and have them spec their designs in the same way. This is what we do on the Facebook design team. I mocked up an example for you (each square is 4dp/8px).

I have a requirement to create a button in a Windows 8.1 app which has an icon and a text label. The icon will be a symbol from Segoe UI Symbols and the text label will be Segoe UI Semibold at a smaller text size.
I want to be able to reuse the button in different places within the app, using different icons and text labels.
How show I go about this? I could create a button and then edit the ContentPresenter to have a horizontally oriented stack panel with two TextBlocks, but then how could I reuse this? And how could I change the text in the two different text blocks?
Should I create a separate custom control with separate dependency properties for each of the textblock strings? I'm interested in hearing what you would do.
thanks
Create a simple Style. To make it easy, I would base it off the standardized AppBarButton style. You can format it to whatever size you want (I have done something similar to make a larger button or one with text on the side).
Have the main icon simply be a ContentPresenter which binds to the Content using a TemplateBinding. Make sure to set the FontFamily to Segoe UI Symbol. Have the text label pull from AutomationProperties.Name, similar to how the AppBarButton style does.
Then, whenever you want to use this just do:
<Button Style="{StaticResource MyCustomButtonStyle}"
Content="" // Where "000" is replaced by the number of the icon you wish to use.
AutomationProperties.Name="Text Label"/>
This should be extensible and easily reproducible to whatever location you need. When copying over the AppBarButton style, I suggest removing the artificial size limits (specifically the width of the main content Grid). I do suggest either giving the Text Label a fixed size or having it pull its size from the specified parent Width, so that it will Wrap correctly.
Hope this helps and happy coding!
Are you desiring to create something like for an AppBar? Take a look at AppBarButton and the style/types it supports. In Windows 8.1 we added some things around SymbolIcon specifically. Since you basically want two pieces of 'content' for your style you'll have to re-purpose one property (unless you create a custom control which doesn't sound needed for this scenario). Using AutiomationProperties.Name for the visible label is a good idea because it will also help with accessibility by default for those users.
Investigate the style for AppBarButton to get you started.
I've been looking for a solution for this one all day.
I have 4 NSTextFields (actually subclassed for a few custom operations), which all share the same X position.
The problem is, some have different styles (light, regular, bold) and might have different sizes.
What happens is that, even though the X origin is the same, the 1st letter always has a bit of (consistently different) left margins.
Please see pic: https://dl.dropbox.com/u/1977230/Screen%20Shot%202012-12-11%20at%2017.55.58.png
I want to make sure that all lines start exactly at the same point, say 100px from the left.
Any idea how to override that weird padding?
Cheers
The margin you're talking about I'm pretty sure is the lineFragmentPadding on the NSTextContainer that is used by the NSTextField.
See the NSTextContainer reference:
http://developer.apple.com/library/Mac/#documentation/Cocoa/Reference/ApplicationKit/Classes/NSTextContainer_Class/Reference/Reference.html
And here's a page from the tutorial on Text Layout:
https://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/TextLayout/Concepts/CalcTextLayout.html
It states in that article:
The typesetter makes one final adjustment when it actually fits text
into the rectangle. This adjustment is a small amount fixed by the
NSTextContainer object, called the line fragment padding, which
defines the portion on each end of the line fragment rectangle left
blank. Text is inset within the line fragment rectangle by this amount
(the rectangle itself is unaffected). Padding allows for small-scale
adjustment of the text container’s region at the edges and around any
holes and keeps text from directly abutting any other graphics
displayed near the region. You can change the padding from its default
value with the setLineFragmentPadding: method. Note that line fragment
padding isn’t a suitable means for expressing margins; you should set
the NSTextView object’s position and size for document margins or the
paragraph margin attributes for text margins.
Unfortunately, it looks like NSTextField's NSTextContainer and NSLayoutManager are private and inaccessible, but it appears they are accessible in an NSTextView:
https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/ApplicationKit/Classes/NSTextView_Class/Reference/Reference.html#//apple_ref/occ/cl/NSTextView
So that may be the class you need to subclass if you want to have minute control over this kind of functionality.
Have you looked into CoreText? I think it may provide the facilities to do what you're looking for. From the docs...
The Core Text layout engine is designed specifically to make simple text layout operations easy to do and to avoid side effects.
You are able to access "font metrics," which enable you to (from the docs)...
For every font, glyph designers provide a set of measurements, called metrics, which describe the spacing around each glyph in the font. The typesetter uses these metrics to determine glyph placement. Font metrics are parameters such as ascent, descent, leading, cap height, x-height, and so on.
EDIT:
It just may be that NSTextField was not designed for what you are trying to do. NSTextField does custom layout apart from a NSLayoutManager.
You may need to upgrade to a NSTextView, which always has a dedicated NSLayoutManager attached. Apple has some example projects you could search for using NSLayoutManager and NSTextView.
If you're using NSTextField to draw simple static text, take a look at AppKit additions to NSString. Use sizeWithAttributes: to get size of the "text" image. Then use the size to calculate rects for drawing. Finally use one of draw methods to actually draw text. Don't forget to "round" result of sizeWithAttributes! It's not pixel aligned.
But if you need to draw something more complex than simple label, use Core Text. You can find very good example of how to use it in twui source code.
When I am changing the font of a label to anything other than the default, the label's font never changes. I can change the font size but not the displaying font. However, when I double click on the label, I can see what the label's font would look like. Can anyone help me with this?
Not all fonts are available on the iPhone. If you are setting the font to an unavailable one, it will default to helvetica. Search the net for a list of the fonts you can use.
You can reference http://iosfonts.com/ for fonts available for each version of iOS. Fonts outside this list will appear as Helvetica, as jrturton said.
I would suggest expanding the size of the text box, by dragging its outermost edges? Despite having made your changes if the selected font/font size combo is to large for the text box to handle it will remain smaller than what you selected even though when you go into the highlight view it appears correct
Edit
Just Because its in that font selection tool does not mean it will show up on the device
