Based on the qt6-make branch with some more cleanup regarding Qt version checks.

By the way: I have to take a closer look at git-branches. How to use them and so ...

In der Firmensammlung funktioniert das (noch) nicht.

KORREKTUR:
In der Firmensammlung funktioniert das genauso!

In the meantime, I have written a code that creates a position list with links and targets in the print module that can be used to insert PDF links.
I just haven't found anything in the Qt docs that explains what a link or a corresponding target should look like so that it works in the PDF file!

There are also additional constraints such as fitting on the page or the print area. "Automagic" zoom factors are used here, which also have to be applied to the positions of the links and targets.

Da waren noch mehr Fragen in meinem Post!

Der Quellcode hat sich also nicht geändert und hier liegt nun eine weitere Kopie einer knapp 70MB großen Datei, die im anderen Beitrag schon angehängt ist?

You're already now free to use any font you like, RedBaron!

If you need osifont for your elements and schematics: use it!

BTW: This part of forum is about import of dxf to elements.

Hallo Xander,

damit wir das alles besser verstehen können:
Vielleicht beschreibst du in ein paar Sätzen, was Du erreichen willst, welche Voraussetzungen im Schaltplan erfüllt sein müssen, etc. pp.

Grafisch ist das schon mal ziemlich beeindruckend!

@vadoola:

As also discussed in the other thread:
We are about to ship a few free fonts with QET. Among them is “osifont” which is often used as a font for CAD applications.
What do you think about specifying “osifont” as a font in converted elements for which no font is specified in the DXF?

When I look at the title block of the well-known “Wet Location Grip” file in LibreCAD and compare the font with “osifont” in QET, the font fits much better than a sans serif font.

Would like to have attached a screenshot, but something's still wrong with forum-settings: I cannot attach a file!

It will be a challenge, to resolve all XRefs! 

Some words about licenses.

To start with: I am not a lawyer!
If I understand it correctly, the MIT licence is the most permissive; even commercial use is allowed with acknowledgement of the original author.

Hallo Re-searcher!

Lass mich auf Deutsch anfangen, Englisch ist weiter unten.

Worin liegt der Unterschied zwischen diesen beiden Code-Fragmenten für "diagram.cpp":

QPen point(Qt::black, 1);
p -> setPen(point);

und

pen.setWidth(settings.value(QStringLiteral("diagrameditor/grid_pointsize"), 1).toInt());

Ich sehe diese Unterschiede:
Im ersten Fragment wird eine hardcodierte "1" als Stiftbreite eingetragen und im zweiten wird eine Stiftbreite aus der Konfigurationsdatei geladen. Ist kein Wert in der Konfigurationsdatei vorhanden, wird eine "1" eingetragen.

Im Ergebnis steht in beiden Fällen eine "1" als Stiftbreite.

Einen Nachteil hat das erste Code-Fragment aber leider: Es wird eine möglicherweise vorgegebene Stiftfarbe hardcodiert durch "Qt::black" ersetzt!

Nun zur Datei "elementview.cpp".

pen.setWidth(5);

und

pen.setWidth(settings.value(QStringLiteral("diagrameditor/grid_pointsize"), 1).toInt());

Im ersten Fall wird die Stiftbreite hardcodiert auf "5" gesetzt und im zweiten Fall auf den Wert aus der Konfigurationsdatei.

p -> drawLine(QLineF(gx - 0.8, gy, gx + 0.8, gy));
p -> drawLine(QLineF(gx, gy - 0.8, gx, gy + 0.8));

und

p -> drawLine(QLineF(gx - (pen.width()/4.0), gy, gx + (pen.width()/4.0), gy));
p -> drawLine(QLineF(gx, gy - (pen.width()/4.0), gx, gy + (pen.width()/4.0)));

Im ersten Fall wird die Linienlänge um von "-0.8" bis "+0.8" definiert und im zweiten Fall auf "Stiftbreite geteilt durch 4".
Für den Fall "Stiftbreite = 5" ist das Ergebnis identisch.

Zusammenfassung:
In einem Fall sind die Stiftbreiten hardcodiert und im zweiten Fall kommt die Stiftbreite aus der Konfigurationsdatei. Bei gleicher Einstellung für die Stiftbreite ist das Ergebnis auf dem Bildschirm das gleiche.
Seit ein paar Tagen ist die Raster-Punktgröße für den Schaltplaneditor und den Element-Editor sogar getrennt einstellbar, sodass man unterschiedliche Werte haben kann: Zum Beispiel "1" für den Schaltplaneditor und "5" für den Element-Editor, wie es in hardcodiertem Code der Fall wäre.

So ist Deine Idee mit anderer Punktgröße für das Raster in den Quellcode von QElectroTech gelangt, Re-searcher!
Die Ergänzung, daß es konfigurierbar ist, kann für die Benutzer nur von Vorteil sein.

Daß Du keine grafischen Artefakte siehst: Freue Dich doch!
Die fallen je nach Pixelgröße des Bildschirms optisch weniger auf!
Du hat einen UHD-Monitor, nicht wahr?

Ich hoffe, dass mit dieser Erklärung deutlich geworden ist, dass es ausdrücklich nicht darum geht, den Code-Vorschlag von jemandem nicht umzusetzen, sondern für uns und die Nutzer von QET eine gute Lösung zu haben!

Beste Grüße

Hello Re-searcher!

What is the difference between these two code fragments for "diagram.cpp":

QPen point(Qt::black, 1);
p -> setPen(point);

and

pen.setWidth(settings.value(QStringLiteral("diagrameditor/grid_pointsize"), 1).toInt());

I see these differences:
In the first fragment, a hardcoded "1" is entered as the pen width and in the second, a pen width is loaded from the configuration file. If there is no value in the configuration file, a "1" is entered.

The result in both cases is a "1" as the pen width.

Unfortunately, the first code fragment has one disadvantage: a possibly predefined pen color is hardcoded and replaced by "Qt::black"!

Now to the "elementview.cpp" file.

pen.setWidth(5);

and

pen.setWidth(settings.value(QStringLiteral("diagrameditor/grid_pointsize"), 1).toInt());

In the first case, the pen width is hardcoded to "5" and in the second case to the value from the configuration file.

p -> drawLine(QLineF(gx - 0.8, gy, gx + 0.8, gy));
p -> drawLine(QLineF(gx, gy - 0.8, gx, gy + 0.8));

and

p -> drawLine(QLineF(gx - (pen.width()/4.0), gy, gx + (pen.width()/4.0), gy));
p -> drawLine(QLineF(gx, gy - (pen.width()/4.0), gx, gy + (pen.width()/4.0)));

In the first case, the line length is defined from "-0.8" to "+0.8" and in the second case to "pen width divided by 4".
In the case of "pen width == 5" (as in pen.setWidth(5)), the result is identical.

Summary:
In one case the pen widths are hardcoded and in the second case the pen width comes from the configuration file. With the same setting for the pen width, the result on the screen is the same.
Since a few days, the grid point size for the circuit diagram editor and the element editor can even be set separately, so that you can have different values: For example "1" for the schematic editor and "5" for the element editor, as would be the case in hardcoded code.

This is how your idea with a different point size for the grid got into the source code of QElectroTech, Re-searcher!
The addition that it is configurable can only be an advantage for users.

That you don't see any graphical artifacts: Rejoice!
Depending on the pixel size of the screen, they are less noticeable!
You have a UHD monitor, don't you?

I hope that this explanation has made it clear that it is explicitly not about not implementing someone's code proposal, but about having a good solution for us and the users of QET!

@scorpio810:

Something's wrong with the forums' attachments, Laurent!
This afternoon, I attached a file and it was marked as "not allowed to download"
And now I don't see any attachment in the forum!

But it doesn't hurt to have such a script... 

We need to inform the users, that we provide default-fonts for all systems from date x.
And we should also point out that the font should be chosen if users are thinking about or relying on cross-system data exchange.

Do we need to adjust the Elements-Collection, too?
This could be done with a small script, but we would need to agree on which fonts to replace with which others:
Sans Serif or Arial --> Liberation Sans
Serif or Times New Roman --> Liberation Serif
MS Shell Dlg --> ???

For the time of the changeover to ‘Liberation Sans’ as default-font:
Should we give our win users the option to change the default font to ‘Liberation Sans’ in the registry?
This could be done with a *.bat, *.cmd or *.reg file, I think...

EDIT:
This should be it:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\QElectroTech\QElectroTech]
"diagramitemfont"="Liberation Sans"
"diagramitemsize"=dword:00000009
"diagramitemstyle"="Regular"
