Unsolved QTextEdit HTML font issue

I have run into the same problem using Qt 5.15.2.
Setting fontFamily(name) on QTextEdit will not change the font name, but append it as a secondary name, causing QTextEdit to not show the correct font, since it uses the first font name.

This does not happen if QTextEdit is set with a plain text, but setHtml(ht) will cause the problem.
The following code example shows the problem without using UI.
QTextEdit te; // Start by setting a text using Arial te.setFontFamily("Arial"); te.setText("ABC"); // The html output shows ... font-family:'Arial' QString html = te.toHtml(); qDebug() << "html 1" << html; // Then select all text and change font to Calibri QTextCursor crs = te.textCursor(); crs.movePosition(QTextCursor::Start); crs.movePosition(QTextCursor::End, QTextCursor::KeepAnchor); te.setTextCursor(crs); te.setFontFamily("Calibri"); // The html output is still good with ... font-family:'Calibri' html = te.toHtml(); qDebug() << "html 2" << html; // Change the font back to Arial te.setFontFamily("Arial"); // The html output is still good with ... font-family:'Arial' html = te.toHtml(); qDebug() << "html 3" << html; // Now set the text using the good html with Arial te.setHtml(html); // Again select all text and set the font to Calibri crs = te.textCursor(); crs.movePosition(QTextCursor::Start); crs.movePosition(QTextCursor::End, QTextCursor::KeepAnchor); te.setTextCursor(crs); te.setFontFamily("Calibri"); // Now the html output is bad with ... font-family:'Arial','Calibri' html = te.toHtml(); qDebug() << "html 4" << html;
The output from above code:
html 1 "<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN" "http://www.w3.org/TR/REC-html40/strict.dtd">\n<html><head><meta name="qrichtext" content="1" /><style type="text/css">\np, li { white-space: pre-wrap; }\n</style></head><body style=" font-family:'MS Shell Dlg 2'; font-size:8.25pt; font-weight:400; font-style:normal;">\n<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;"><span style=" font-family:'Arial';">ABC</span></p></body></html>"

html 3 "<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN" "http://www.w3.org/TR/REC-html40/strict.dtd">\n<html><head><meta name="qrichtext" content="1" /><style type="text/css">\np, li { white-space: pre-wrap; }\n</style></head><body style=" font-family:'MS Shell Dlg 2'; font-size:8.25pt; font-weight:400; font-style:normal;">\n<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;"><span style=" font-family:'Arial';">ABC</span></p></body></html>"

html 4 "<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN" "http://www.w3.org/TR/REC-html40/strict.dtd">\n<html><head><meta name="qrichtext" content="1" /><style type="text/css">\np, li { white-space: pre-wrap; }\n</style></head><body style=" font-family:'MS Shell Dlg 2'; font-size:8.25pt; font-weight:400; font-style:normal;">\n<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;"><span style=" font-family:'Arial','Calibri';">ABC</span></p></body></html>"

where the last line with font-family:'Arial','Calibri' is not as expected.
It should only say Calibri to work correctly.

Kind regards

@jsulm Thank you so much. Your solution works perfectly.

Here is the code if anyone is interested:

QTextEditSubClass.h:
#ifndef QTEXTEDITSUBCLASS_H #define QTEXTEDITSUBCLASS_H #include <QTextEdit> class QTextEditSubClass : public QTextEdit { Q_OBJECT public: explicit QTextEditSubClass(QWidget *parent = 0); ~QTextEditSubClass(); // QWidget interface protected: void wheelEvent(QWheelEvent *event) override; }; #endif // QTEXTEDITSUBCLASS_H
QTextEditSubClass.cpp:
#include "qtexteditsubclass.h" #include "qapplication.h" #include "qevent.h" QTextEditSubClass::QTextEditSubClass(QWidget *parent) { } QTextEditSubClass::~QTextEditSubClass() { } void QTextEditSubClass::wheelEvent(QWheelEvent *event) { bool controlKeyIsHeld = QGuiApplication::keyboardModifiers().testFlag(Qt::ControlModifier); // If vertical mouse wheel goes up, then zoom in. if(event->angleDelta().y() > 0 && controlKeyIsHeld) { this->zoomIn(1); return; } else if(event->angleDelta().y() < 0 && controlKeyIsHeld) { this->zoomOut(1); return; } QTextEdit::wheelEvent(event); }
After creating this sub class, we simply create a new instance of this class and pass it to the mainwindow central widget.

Hope this helps.

Oh.. I figured it out.
That's just a simple unit conversion error.

I used millimeter instead of pixel...
>>> # Python >>> __editor.mmMarginLeft() 20 >>> __editor.pxMarginLeft() 110 >>> __editor.mmMarginLeft() == __editor.pxMarginLeft() False
Now it's solved! THANKS a lot!

This looks similar to what https://forum.qt.io/topic/141297/exception-about-qt-creator-ui-on-ubuntu experienced.

Also on VMware.

I assume it has something to do with the graphics drivers. At https://www.qt.io/blog/qt-6.4-released we can see the topic:

QQuickWidget with full RHI support

With QQuickWidget you can build application user interfaces where Qt Quick and Qt Widget elements coexist. Until now this required using OpenGL. For Qt 6.4 we redesigned the class from the ground up, and now QQuickWidget is functional with all supported graphics APIs: Metal, Vulkan, Direct3D 11, in addition to OpenGL.

Can you post the Graphics configuration of your VMware player? Aso a bug report at https://bugreports.qt.io/ wouldn't hurt either.

@Mr-Workalot But what location do you need? Where do you want to store the file? It is really not clear from your description.
Did you check the link I provided: https://doc.qt.io/qt-5/qstandardpaths.html ?
Example: to store in Documents folder call https://doc.qt.io/qt-5/qstandardpaths.html#writableLocation with QStandardPaths::DocumentsLocation as parameter

@SGaist
My data is ready to append. So i append them directly. There are 10-100 QTextEdits. I append 100-200 line to each of QTextEdits. Lines have arround 300 characters. I have one vector of vectors source.
By the way, i moved my data source to a different thread. Then emitted signals to append with BlockingQueuedConnection. Gui is responsive now. But its not smooth. I dont know using blockingqueuedconnection instead of queuedconnection is the right way but my gui is responsive while appending strings now.

The following partially works and I post in the hopes that someone might get an idea that will fix my issue :)
bool ZoomCode::event(QEvent *event) { if (event->type() == QEvent::NativeGesture) { return gestureEvent(static_cast<QNativeGestureEvent*>(event)); } return QWidget::event(event); } bool ZoomCode::gestureEvent(QNativeGestureEvent *e) { float value = e->value(); textEdit->setFontPointSize(NULL); // zoom does not work without this textEdit->selectAll(); // some part of the text has to be selected before the zoom in the text starts to work. It does NOT matter if it is the WHOLE text or just a character in the text, just as long as something gets highlighted. Afterwards, nothing has to be highlighted again for the zoom to work. The zoom works on the whole text, no matter what part has been highlighted. if(value >0) { zoomIn(value + 5); // + 5 to add some zoom strength } else if(value < 0) zoomOut(value - 5); // -5 to add some zoom strength } }

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.
