I have the problem that the text on three UIButtons gets wrapped to several lines in the Interface Builder, but when I run the code, the text is larger than the button and in one line only. I tried setting NSLineBreakMode and NSTextAlignment, but both didn't help.
In the Interface Builder it looks correctly like this: http://imgur.com/WplkqQV while on the simulator it looks like this: http://imgur.com/0YPpEfU. Any ideas?
Thanks in advance.
There is certainly something very odd about your example; I can't reproduce it. You must be doing something to the buttons that you have not described in the information provided by your question. If you set up your button line break mode to be Word Wrap (in the nib), and if your constraints are sensible so that the button can get wider in landscape and narrower in portrait, then it will wrap in portrait and not in landscape, which I believe is what you want. Here are screen shots of a button in the Simulator on my machine (ignore the actual widths of the buttons; it's only an example; what's important is the text wrapping):
The real problem, however, is the height. You'll notice that that isn't changing. This is because a round rect button has an intrinsic height value. If you want the height to change, to make more vertical room for the wrapped text, you will probably need to subclass or intervene in the layout process after rotation. For example, I get pretty nice results like this:
-(void)viewDidLayoutSubviews {
CGRect f = self.button.bounds;
if (UIInterfaceOrientationIsLandscape(self.interfaceOrientation))
f.size.height = 44;
else
f.size.height = 60;
self.button.bounds = f;
}

In a UITextView I want to draw ruled lines along with the text. For that, I subclass UITextView and overwrite drawRect. Seing a few post on the subject (including on this site), that seems the right way to start.
Here is the loop where I draw the lines:
for (int x=1;x<numberOfLines;x++) {
yPos=self.font.lineHeight*x+baselineOffset;
CGContextMoveToPoint(context,self.bounds.origin.x,yPos);
CGContextAddLineToPoint(context,self.bounds.size.width,yPos);
}
baselineOffset in this code is constant, meaning I step by self.font.lineHeight
but seeing the picture below (with the slow shifting between the lines and the text) I am obviously not using the right value for incrementing
the y coordinate (here called yPos). What should I use?
Has anyone got an idea of what could be the problem?
Thank you for any tip.
Use font.leading instead of font.lineHeight.
I have created a circular UIButton by setting the cornerRadius property to half of the width and height values of the UIButton.
btn.layer.cornerRadius = 75.f;
That works fine but I would like to also create a label for the UIButton where the label text curves around the edge of the UIButton.
If this is even possible could somebody post a snippet of code as to how this curved text around the button edge could be accomplished?
You might have a look at this question: Curve text on existing circle
It's not actually a UIButton, but you will certainly get an idea of how to draw text on a curve.
There's especially talk of the sample project CoreTextArcCocoa from Apple. It's for OS X instead for iOS, but you might want to check this out.
I'm trying to make a page with two overlapping div's, one aligned to the left with the float:left attribute, and the other next to it, but overlapping by means of a negative margin.
Despite all this, I just get text as my output when I preview in browser from Dreamweaver. Problem is, it looks exactly how I want it in DW's preview pane.
Here is the jsFiddle, and how it looks in Dreamweaver.
Try swapping positions of the #img div, and the #titlebar div; AND make sure both are set to 'float:left'.
(#img div first, then #titlebar div in the HTML)
I'm using LaTeX and I would like to have vertical rule along left side of page, topmargin to bottommargin, 0.5in from the left edge of the page. I want this on every page, so I assume that means it must somehow be tied to the header or the footer?
I've made no progress at all, so I need help with (1) making the full-length rule itself and (2) making it happen automatically on every page of the document.
Can someone tell me how to do that?
I got a working answer to my question on the Latex Community forum: http://www.latex-community.org/forum/viewtopic.php?f=5&t=9072&p=34877#p34877
The answer I got uses the 'Background' package and this code:
\documentclass{article}
\usepackage{background}
\usepackage{lipsum}% just to generate filler text for the example
\SetBgScale{1}
\SetBgAngle{0}
\SetBgColor{black}
\SetBgContents{\rule{.4pt}{\paperheight}}
\SetBgHshift{-9cm}
\begin{document}
\lipsum[1-90]
\end{document}
Works great and was easy to adjust to put one vrule in left margin area and one in the right margin area.
There could be a LaTeX package to do this for you, but I'm more of a TeX person, so I tried to come up with a TeX solution (not always the best idea to mix plain TeX with LaTeX but I think I have it working).
Try this. Box 255 is the box register that TeX places the page contents into before the page is output. What I've done is taken the existing output routine, and changed it to insert into box 255: a 0-height, 0-width infinitely shrinkable-but-overflowing set of boxes containing a rule that is the height of the page, 0.4pt thick and with any luck, half an inch away into the left. The existing contents of box 255 is then added after this rule. Then I call the previous output routine which outputs the page (which now includes a rule), and also the headers and footers.
\newtoks\oldoutput
\oldoutput=\expandafter{\the\output}%
\output{%
\setbox255\vbox to 0pt{%
\hbox to 0pt{%
\vsize\ht255%
\vbox to \ht255{%
\vss
\hbox to -0.5in{%
\hss
\vrule height \ht255 width 0.4pt%
}%
}\hss
}\vss
\box255%
}%
\the\oldoutput
}%
Put it before your \begin{document} command. This might not solve your problem completely, but hopefully it should get you started. Here's a great page for learning about TeX primitives and built-in things.
Have a look at the eso-pic package. From memory, what you want would look like this:
\AddToShipoutPicture{%
\setlength\unitlength{1in}%
\AtPageUpperLeft{%
\put(0.5,\topmargin){\vrule width .5pt height \textheight}%
}%
}
It's not clear in your question if you want the line to span the text area or the whole paper height. Depending on the case, you have to replace \topmargin and \textheight by the correct values, either 0pt or whatever your top margin is, or by \paperheight. See the geometry package if you don't already use it for how to control those dimensions.
How do you determine the length of a string of text in Arial Bold font, and then center it in VB6?
We are not using a "label" or "picture box" to print the text to the screen. We are sizing the text on the fly, and allowing the user to scale the size of our application to their liking. We write the text to screen using code.
One way is to have a hidden picture box and setup the font specs of that picture box the way you want.
Then use the TextHeight and TextWidth methods of the PictureBox to take your measurements. The Units will be in whatever scalemode the Picture Box is set to.
If you are printing directly to the printer or form then just set your font FIRST then take your measurements.
To center it
MyText = "Hello World"
<displayarea>.FontName = "Arial"
<displayarea>.FontSize = 14
<displayarea>.FontBold = True
TextWidth = <displayarea>.TextWidth(MyText)
TextLeftCoordinate = <displayarea>.ScaleLeft+<displayarea>.ScaleWidth/2-TextWidth/2
<displayarea>.CurrentX = TextLeftCoordinate
<displayarea>.Print MyText
Substitute displayarea with whatever object you are using.
Based on your updated answer note that the hidden picture box suggestion isn't used to print. It is only get text measurement. However you are printing directly to the form so you just need to use the code example above.
I can't remember the specifics (it's been about 3 years since I last used VB 6), but there's a method on Form called something like "MeasureString". It takes the string, and measures it according to the font settings of the form.
Also, here's a comment posted by Jason Lepack in case I've misunderstood and over-complicated your requirements:
"Labels usually have an alignment property. If you set it to align to center then, regardless of the font face it should center in the label".
There are Win32 GDI functions you can invoke: see for example GetTextExtentPoint32 at http://msdn.microsoft.com/en-us/library/ms534223(VS.85).aspx
Your best option may be Form.TextWidth, which appears to return the width of a string in twips. I've just taken this approach in order to dynamically size a button based on the length of the label that needs to appear inside it.
There is also a corresponding function called Form.TextHeight which would allow you to do the same thing in the vertical dimension.
Make sure that you set the Font property of the form to match the Font property of the control you're intending to measure the text for, otherwise you'll get incorrect results.
