I want to change the text of my status bar:
pView->m_pWndStatusBar->SetWindowText( _T("Refreshing...\t\tFiltered") );
The above code is not accepting the escape character \t.
The output is:
Refreshing...
Expected output:
Refreshing...[tab][tab]Filtered
According to MSDN you cannot use tabs in strings passed to SetWindowText:
The SetWindowText function does not expand tab characters (ASCII code 0x09).
I recommend to use spaces instead of tabs in your status bar.
In case you want to use tabs to align text of a different control (e.g. CStatic) then I recommend to use an additional control. The original control gets the text before the tab and the new control gets the text after the tab. Then you can align the controls to each other as you like.

Whenever I paste text into a Google Docs document, all the newline characters get convereted into vertical tab characters (\013 OR \v). This happens regardless of the source of the clipboard text (webpage, word, notepad++).
Usually this means I have to work my way through the document clearing all the vertical tabs and replacing them with proper newlines by backspacing the character and hitting return. However, I want to write a script to replace all the characters in the doc at once. The Replace ui feature doesn't support newline characters but I'm hoping the scripting api does.
I have written the code below, but though it runs, the vertical tab characters are not replaced. I can still see hundreds in the document with the find/replace ui feature. What am I doing wrong?
function myFunction() {
var body = DocumentApp.getActiveDocument().getBody();
body.replaceText("\\v", "\n");
}
I am creating a basic text editor using ncurses. It can display text fine, but navigating with arrow keys causes a problem when tabs are encountered. Calling move(y, x) will freely move the cursor onto a tab space, where most text editors will jump to the next character. Is there functionality within ncurses to jump over tab spaces or do I need to find a way to do it myself?
You have to do it yourself: wmove moves to the given coordinates, ignoring the way characters are displayed on the screen.
If a destructive (filling with spaces) tab works for your application, then you could use waddch:
If ch is a tab, newline, carriage return or backspace, the
cursor is moved appropriately within the window:
Tabs are considered to be at every eighth column. The
tab interval may be altered by setting the TABSIZE
variable.
For an editor, you probably do not want that behavior (though it probably would be helpful to use the TABSIZE feature when displaying text).
I have some text documents (.doc and .odf) with portions of colored code appearing inside.
This code was copied as RTF from Notepad++, that's how it got colored.
However, in Notepad++ (and in many IDEs as well), the line wrap function works makes the indented code look better when in does not fit and goes to the next line.
In LibreOffice/OpenOffice and Ms Word it's possible to achieve a similar line wrap with the "increase indent" button.
So, what I'd like to do, is to automatically replace the tabs (or 4 spaces, if you like) with proper indents. Or make the tabs behave like I expect them to. Is it possible? Thanks.
Here's a visualization of the problem
I achieved what I want through some (not that many) manual steps.
find out what is the maximum number of tabs (or sets of 4 spaces), say it's 3
open the search and replace window, input 3 tabs (or 12 spaces), and click "Find All"
now all groups of 3 tabs are selected, and you are working on all the lines with maximum indentation
park or close the search and replace window, click 3 times on the "Increase indent" button (or set the left indentation in the paragraph style menu)
delete the selected groups of 3 tabs
open the search and replace window, input 2 tabs (or 8 spaces), and click "Find All"
park or close the search and replace window, click 2 times on the "Increase indent" button
delete the selected groups of 2 tabs
open the search and replace window, input 1 tabs (or 4 spaces), and click "Find All"
park or close the search and replace window, click 1 time on the "Increase indent" button
delete the selected single tabs
Now you have a nice code indentation.
If you are using Microsoft Word, then there's no "find all", but there is a way to apply paragraph styles directly from the search and replace menu. But the steps are a little different.
First decide how wide a single indentation should be (e.g. 0.5 cm)
open the find and replace window, input 3 tabs (or 12 spaces) in the Find bar
leave the Replace bar empty, but click on it
if you don't see the Search options group, click More
click on Format
click on Paragraph
set a left indentation of 3 * the indentation width you want (e.g. 1.5 cm)
click Replace All, the paragraph style will be applied but the tabs/spaces will NOT be removed
click on the empty Replace bar (again)
click No Formatting
click on Replace All (again)
now the tabs/spaces will be deleted
Rinse and repeat until you get a nice indentation.
If you are using Python (or if you want to keep your white spaces) then instead of deleting the tabs (or spaces), you can replace them with a placeholder character you don't use in the rest of the code, say £ and replace them back in one pass when you are done. However, you'll get a skewed indentation.
I guess there's a way to do this with macros, but this was good enough for me.
I am using brackets with coffeescript, but when I hit Tab, it insert a tabulation whereas i only need 2 spaces. Also, when I create a line break, the indent is tabs, and not spaces. Can I change these 2 setting ?
In the lower-right of the status bar you should see an indicator saying "Tab Size." Click the label to toggle to spaces. To change the amount of indent, click the number next to it and type a new value.
Note: if the indicator already says "Spaces" then Brackets should be using spaces instead of tab characters already. But it might not feel that way because when you move the cursor or press Backspace, there's a "soft tabs" behavior: the cursor will smartly skips over contiguous spaces to line up evenly with the next tab stop. If that bothers you, there will be a preference in the next release of Brackets (Sprint 38) to disable that behavior, making the cursor never move more than one space at a time.
For language specific control, Brackets allows you to provide different tab and space indentation values in the brackets.json file. For example:
"language": {
"html": {
"spaceUnits": 4
},
"javascript": {
"tabSize": 2
}
}
For changing tab spacing you can edit your brackets.json file. you can find it on Debug->Open Preferences File and simple add "spaceUnits": 2 at the end of the file for 2 space. Remember to add a comma on previous line. You can edit that file for customizing your bracket.
Or you can change it more easily at the right-bottom of your bracket interface you saw a option Space: 4 click on the number and change it as your wish...
I'm rendering some HTML in a QT QLabel. The HTML looks like this:
<pre>foo\tbar</pre>
(note that I've put "\t" where there is a tab chracter in the code).
This renders fine, but the tab character appears to be rendered as eight spaces, whereas I want it to be redered as 4. How can I change this without having to change the source HTML?
According to W3 (HTML4):
The horizontal tab character (decimal 9 in [ISO10646] and [ISO88591]) is usually interpreted by visual user agents as the smallest non-zero number of spaces necessary to line characters up along tab stops that are every 8 characters. We strongly discourage using horizontal tabs in preformatted text since it is common practice, when editing, to set the tab-spacing to other values, leading to misaligned documents.
It's implementation-defined, essencially. Most, if not all, browsers/renderers use eight spaces for tabs. This cannot be configured in Qt.
It is, however somewhat trivial to go through your HTML and replace tabs with however many spaces you wish. Write a simple parser for that. Pseudocode:
for each <pre> block {
for each line in block {
position_in_line = 0
for each character in line {
if character is a tab {
remove tab character
do {
add a space character
++position_in_line
} while position_in_line % 8 != 0
} else {
++position_in_line
}
}
}
}
In case you're curious, HTML3 specifies the use of eight-character tabs:
Within <PRE>, the tab should be interpreted to shift the horizontal column position to the next position which is a multiple of 8 on the same line; that is, col := (col+8) mod 8.
While QLabel uses a QTextDocument internally when rendering rich text, it does not allow access to it in it's API. However, since QTextDocument is a QObject, you can try to use
QTextDocument * tl = label->findChild<QTextDocument>();
to get access to it (will work if the QLabel creates the QTextDocument as a (direct or indirect) child of itself).
Once you have a pointer to the text document, you can use the QTextDocument API, e.g. QTextOption::setTabsStop(), to change the tab stops.
The last step is to somehow make the QLabel repaint itself. Probably a call to QWidget::update() suffices, but caching (or worse, recreating the text document) might thward that. In this case, you can register an event listener on the label to adjust the text document just prior to a paintEvent(), but note that the sizeHint() might also change when the tab stops change, so it might be more complicated still.
That said, it's how I'd approach the problem.
Try this:
<pre style="tab-interval:0.5in">foo\tbar</pre>
Could work
