Unfortunately, it doesn't seems to work... actions() returns me an empty list.

I think I'll go for QTextEdit::createMimeDataFromSelection() because otherwise I won't be able to deal with drag & drop (I didn't think about it :/ )

Thanks anyway!

@kshegunov Right... Thanks, something didnt trigger in the brain. Now its fine:

connect(uap, &CUaProxy::uaItemChanged, this, [this, i]( const CUaProxy::MsgType msgt, const int riskIndex, const QVariant& value) { this->onUaMsgReceived(msgt, i, riskIndex, value); }, Qt::QueuedConnection);

Also needed Qt::QueuedConnection eventually.

@KillerSmath @raven-worx Thanks. I will try it and post the result later. I think it's a non-trivial task.

QTextEdit::toHtml() gibt schon gültiges HTML zurück - nicht nötig da noch einmal was zu konvertieren (was eh nicht mehr vorhanden ist). ß wird übrigens falsch konvertiert...

Hello, I reply this old topic but I could not find a solution for a problem. I want to set the padding of the text editor to zero.

textEdit->document()->setDocumentMargin(0);

as @mpergand said this works. However when I try to design application for different platform a problem occurred.
On the mac the text is fit all the width of the texteditor, but in android there is always a small space at the end.

Both text editors' width set to 150, on mac 45 of letter i can fit, on the phone 44i can fit and the small space.

I tried all the below , none of them works

part of the code:

QTextDocument *doc = textEdit->document(); doc->setDocumentMargin(0); doc->setIndentWidth(0); textEdit->setContentsMargins(0,0,0,0); // textEdit->set QTextCursor cursor(doc); // Select the entire text cursor.select(QTextCursor::Document); // Create a character format and set the font style QTextCharFormat format; // QFont font("Arial", 12, QFont::Bold); // Example: Arial, 12pt, bold format.setFont(timesFont); // Apply the format to the selected text cursor.mergeCharFormat(format); // Set block format to ensure no extra margins QTextBlockFormat blockFormat; blockFormat.setBottomMargin(0); blockFormat.setTopMargin(0); blockFormat.setLeftMargin(0); blockFormat.setRightMargin(0); cursor.setBlockFormat(blockFormat); textEdit->setTextCursor(cursor);

Why there is a difference ?

@Alain38 OK: It seems in fact that wat just a problem with the console. By sending the text to the URL (using QUrlQuery for encoding) I have the text with the accents.

If you put your buttons in a QButtonGroup you could simply store the button id so you can programmatically check it when loading your document.

@mrjj
I don't want to resize it via a dialog. I need to do that with the mouse (manually)

I have found a solution suiting me.

QRegularExpression rexp ( "<img src=\\\"([^\\\"]{1,})([^/]{0,})/>" ); QRegularExpressionMatch match; int pos = content.indexOf ( rexp, pos + 1 ) ; if ( pos > -1 ) { match = rexp.match ( content, pos ); if ( match.isValid() ) { QString imFile = match.captured ( 1 ); } }

imFile will hold the file name stored.

Or as alternative for the deprecated QRegExp. The expression itself works for both.

QRegExp rexp ( "<img src=\\\"([^\\\"]{1,})([^/]{0,})/>" ); int pos = content.indexOf ( rexp ); if ( pos >= 0) { QString imFile = rexp.cap ( 1 ); }

Note: The indexOf with QRegularExpression may also handle the QRegularExpressionMatch since version 5.5. This would make it more compact.

Hi

if setAlignment sets the alignment for a paragraph of text
(see doc)

When you do
ui->QtexteditObj->setText

I think it replaces the paragraph with a new one since u replace all text
and the default alignment is left for that new paragraph

Just guessing. Did not test it :)

The QPixmap class has a constructor that takes a QSize parameter and therefore allows you to create a pixmap of a given size. That is what @jsulm is doing in the first line of his last code example. Documentation.

Hi,

It might be not possible to insert a QChart object directly but a possible alternative might be to generate your chart, render it on a QImage and then put that QImage your QTextDocument.

Hope it helps

Looks like it might be a limitation/bug. The behavior is the same with 5.6

You should go to the bug report system to see if it's something known. If not please consider opening a new report providing a minimal compilable example (not just the code files) to reproduce the behavior.

I have elucidated the dilemma regarding the doubt raised.

First and foremost, I was confusing two concepts, TextEdit and TextDocument for the first contains the second, although they can be used interchangeably on any widget.

On the other hand, I prefer QTextEdit, it has more features and is more versatile than QPlainTextEdit for creating a text editor and so investigated have equal performance in terms of resources used.

I leave this reflection or as a solution in case someone is presented with any questions regarding this topic.

@raven-worx Thanx for the suggestion. I think we can go a long way with this, except that we are on Windows and it seems we need some Windows-specific MIME-conversions. We'll try to tinker a bit with that.

The cause for that crash can be everything!
How should anybody know what it is without your code?
Did you try to debug your program to see where it crashes?

Then you should rather use an event filter so you'll only test when there's something currently going on with your button.

Ok, thanks.

This solved my problem

@AnkurSharma

But, I also expect that when I am resetting the attribute of WA_InputMethodEvent my widget should no more get the input method events anymore, and thats how it works on Qt on OSX.

I don't know how it works on OSX, I can say for sure though that QObject::eventFilter is executed before the QObject::event method (this is documented) and since you're not giving Qt leeway to process the event as it ordinarily would in the overriden QWidget::event method (you stop the event propagation when you return true from the event filter) you shouldn't expect it to respect the widget attribute. That's what I'm claiming. You should move your code from the eventFilter method to a QWidget::inputMethodEvent override.
