I have a TextArea with the wrapText activated because I need to fully visualize a line with 300 characters. But when I copy and paste the textArea content into a Notepad, I see that it added line breaks.
Does anyone know if this can be changed?
I need to recover the same line with 300 characteres when I copy and paste, without the line breaks

I have a text field and I'm able to change the text size of a Text node no problem with
Text text = new Text();
text.setStyle("-fx-font-size: 16;");
but if I try to change the colour, nothing works:
textStart.setStyle("-fx-font-size: 16;-fx-color: #ff0000;-fx-text-base-color: #ff0000;-fx-text-fill: #ff0000;");
I find in JavaFX every node seems to need a different css command to successfully change the colour, but with Text, none of them seem to work. I can change the text with
text.setFill(Color.RED);
But it's awkward to have two separate commands on separate lines when it should be able to be done in one line of css. Especially since what I'm doing is relatively heavy processing of many lines of text.
Does anyone know what the css command to change the colour is with a Text node? Seems so odd it only accepts the size command in css..
I have a Label that displays the full name and path of the file that the app is currently processing.
The way Labels perform text truncation, the "C:\..." part of the path is always shown, while the actual file name is only shown if it fits. I would rather truncate on the left side, so that the file name is always shown, while the "C:\..." part is only shown if it fits.
Is this possible in Xamarin Forms?
If you read the docs these are the options for truncation
HeadTruncation – truncates the head of the text, showing the end.
CharacterWrap – wraps text onto a new line at a character boundary.
MiddleTruncation – displays the beginning and end of the text, with the middle replace by an ellipsis.
NoWrap – does not wrap text, displaying only as much text as can fit on one line.
TailTruncation – shows the beginning of the text, truncating the end.
WordWrap – wraps text at the word boundary.
HeadTruncation appears to be what you're looking for
I prepare a document in Markdown in which I have to highlight changes in color. I am aware that I could wrap the text like this:
This text is unchanged, however \textcolor{red}{I changed this}, before going back to the original color.
But I would prefer to define my own command, similar to the **<this is bold text>** solution, without all the brackets. I found the following solution to make all bold text also blue, but since I am new to latex I have been unsuccessful trying to adapt this. I found out how to change the textcolor after a custom command for the rest of the document by including this at the beginning of my Markdown document:
\newcommand{\x}{\color{red}}
Like this, the text color switches to red after I write \x somewhere in the text. The next step would be along these lines:
\newcommand{\x}{%
\ifthenelse{\equal{\color}{black}}% if the text color is currently black
{\color{red}}% set it to red
{\color{black}% else set it back to black}}
I want this custom command to check the current text color. Like this, I could ideally have some unchanged text and \x wrap the changed section in the custom command, making this red \x, before going back to the original color.
Does anyone have an idea how I could write this in Latex? Any help appreciated!
Using a similar approach as in https://stackoverflow.com/a/52390056 , you could change the behaviour of **...** to give red text instead of bold:
\renewcommand\textbf[1]{\textcolor{red}{#1}}
I am using QTextdocument and in my text there are "\n" for new line characters but QTextDocument is not handling it and it shows it as plain 1 line .
Is there any way we can make it handle "\n" as new line character, along with that I need eliding also.
So whenever any text is there after line break it should show "..."
E.g. This
is
the
Sample
Currently QTextdocument removed line breaks and shows it as "This is the sample"
2nd issue is for eliding Now suppose only 1 line is visible it should show it as "This..."
How do I achieve this?
QTextDocument holds formatted text, so you can use <br> html tag for a new line and set it's content using QTextDocument::setHtml.
Also you cab use QTextDocument::setTextWidth to set a specific width for text in the document. If the content is wider, it is broken into multiple lines and grows vertically.
About eliding you can see this bug report which is unresolved.
I have a TextArea where the user can enter text and also change the width and height of the TextArea. When resizing, the text is breaking where expected. I need to find where the TextArea skin added the implicit line breaks after resizing.
ENVIRONMENT
FlexBuilder 4.6
Flex SDK 4.6.0
Flash Player 11.1
EXAMPLE
This is just plain text that
breaks after the word "that".
Any ideas on how to find the position of the line break when the TextArea lineBreak property is toFit and the text has no CR or LF characters? In the example above, it would be position 28.
You can split up the text into line components and return their individual text lengths pretty easily, but you'll have to use some 'text layout framework' magic.
First access your TextArea's textFlow property (not the text property), which will return a TextFlow instance. This is a model for the text inside your TextArea.
This object has a flowComposer which takes care of the layout of the text and carries a lot of information with it.
Its type is IFlowComposer, but you'll have to cast it to a StandardFlowComposer in order to access the individual lines.
Now you have access to the lines property, which is a collection of TextFlowLine
Each of these lines has a textLength property.
So the following
var composer:StandardFlowComposer =
myTextArea.textFlow.flowComposer as StandardFlowComposer;
for each (var line:TextFlowLine in composer.lines)
trace(line.textLength)
would yield (with your example)
