I want to set the right alignment for the wrapped text. If I set:
wrapMode: Text.WordWrap
horizontalAlignment: Text.AlignRight
text: "text\ntext"
I will get wrapped text but aligned to right "before" wrapping. Sth like:
text |
text |
instead of
text|
text|
Do I have to set additional params etc.?
Problem solved - we need to use newer QT version (5.2.1 was bugged) or check text width - sth like Measuring text width in Qt

I have a variable-width container (screen width) and fixed left and right margins. Remaining area gives me a constraint for maximum text width, where I'm placing text of variable content (multiple languages). I want text to fit into that width without truncation, wrapping if needed. Text is relatively short - it may fit into single line, likely to fit into 2 lines and will fit into 3 lines for sure.
I want to avoid cases like (2) - where text wraps into long and a short line. It does not look nice. Instead I would like it to wrap more evenly, like in case (3).
For the demo purposes I've hardcoded hand-picked margins, but I want solution to work automatically for any text content and any container width.
Is it achievable using built-in Flutter widgets, or I need to implement something custom, similar to https://pub.dartlang.org/packages/auto_size_text?
I'm looking for a cross-platform rich text widget that supports non-trivial markup including the following, and I wonder if Tk's text widget can be extended to do them:
set text background color
draw lines over and under text
draw borders around text
decorate content by overlaying lines and shapes (e.g., filled circles)
indicate items in a gutter
To give you an idea, look at the middle pane here:
I read a little about tags, but they seem to be limited to the basics like font, color, etc. I also read about drawing text on the canvas widget, but it looks like standard text editor-like text selection, flow, etc. would be lost.
Thanks very much.
In short, you can only do what you've read in the documentation (assuming you've read authoritative documentation).
Specifically, the text widget does not do all that you asked. You cannot do the following:
draw lines over and under text. You can use custom fonts with the overstrike and underline attributes turned on but there's no way to add lines over a widget, and you have no control on the visual attributes of the overstrike or underline
decorate content by overlaying lines and shapes (e.g., filled circles)
You can set text background and foreground colors, draw borders around the text, and put items in a gutter. For the latter you would need to use a canvas as the gutter.
Note that if you use a canvas rather than a text widget you can do all of those things (read: the text items of the canvas can be editable), but it would require a large amount of work to implement all of the bindings necessary to use it as an editor. For more information on this approach, see http://effbot.org/zone/editing-canvas-text-items.htm
I have a view that draws multicolored text inside UITableViewCell. To draw multicolored text I'm using NSAttributedString However, I would like to make it so that if the text is too long to fit into the view, the last visible line is truncated to display an ellipsis at its end.
Obviously this is very easy to do when drawing only a single line, as you can just set
kCTLineBreakByTruncatingTail for the line break mode of the paragraph style. The problem is that I want my text to wrap to fill the rectangle, and then only have the last line truncated with an ellipsis - setting the line break mode confines the whole text to one line.
Does anybody have any ideas of how I would go about this?
Many thanks in advance for any suggestions,
JC.
Create your CTFrame from your CTFrameSetter with the rectangle of your UITableViewCell. Then, you can get all the CTLines of your CTFrame and determine when they will cut off. To swap out the ellipsis, you could keep that drawn with a separate CTFrame and draw it over the overflowing text on the last line.
You can find working code here: https://stackoverflow.com/a/14612598/473067
It's a similar approach to what Heath suggested. But then all wrapped up in a shiny package.
Well, to activate text truncating in UILabel, you should re-set lineBreakMode parameter to NSLineBreakByTruncatingTail after setting attributedText.
textLabel.attributedText = attributedText;
textLabel.lineBreakMode = NSLineBreakByTruncatingTail;
I am trying to send data to a specific MergeField. The data are sent correctly. Each line of the data has for specific characters. For example the data to the field may be:
12345 FIRST\nABCDE.F SECOND
(it cannot get the newline so i just so it through character \n)
Now in the printed document each character has its one width, '1' is smaller than 'E' for example. So the data are not alligned within the field. I tried the following fonts: Arial, Tahoma, Courier New. Nothing helped.
Any ideas? Thanks in advance.
Ps the data are sent through an executable built by Visual C++ 5.0!!
You should probably use a tab-stop based layout. Set your tab-stops every, say, centimetre or so (i.e. just big than the widest character in your font) and add a tab before each element that needs to be aligned.
With this you shouldn't need to find a fixed width font and can use something more attractive.
Edit: Out of interest, I wonder why you have no luck with Courier New which is fixed width.
Maybe you could post a screenshot somewhere so we can have a look at your problem in more detail.
Try Courier - it does not have kerning (kerning = variable character width)
Also in the Font window there is a check box that allows you to apply kerning to fonts of a certain size or above - setting this value to a large font size may remove kerning.
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.
