PageEdit-1.9.10 Released

[KevinH]

I just pushed that change to master along with this earlier snippet from Sigil's main.cpp as well:

#if !defined(Q_OS_WIN32) && !defined(Q_OS_MAC)
    // Unset platform theme plugins/styles environment variables immediately
    // when forcing Sigil's own darkmode palette on Linux
    if (!force_sigil_darkmode_palette.isEmpty() ||
        !force_pageedit_darkmode_palette.isEmpty()) {
        QStringList env_vars = {"QT_QPA_PLATFORMTHEME", "QT_STYLE_OVERRIDE"};
        foreach(QString v, env_vars) {
            bool irrel = qunsetenv(v.toUtf8().constData());
        Q_UNUSED(irrel);
        }
    }
#endif

That appears to work on my Manjaro box under Qt6 and Qt5 with FORCE_PAGEEDIT_DARKMODE_PALETTE=1 set.

Hope that is okay.

Should be fine. I can't think of any specific reason why I would have left it out of PageEdit. It basically just erases any of the system theming env vars from the PageEdit environment whenever the built-in dark mode is being forced. Thanks!

In Arch Linux, after updating Qt from version 5.15.4 to 5.15.5 and rebuilding PageEdit with that new version of Qt, it refuses to start. Why? By running PageEdit from the console, I receive the following message:

Cannot mix incompatible Qt library (5.15.4) with this library (5.15.5)
Abortado (`core' generado)

Since all Qt libraries were updated, what qt 5.15.4 library can be PageEdit using?

[DiapDealer]

As crazy as it may seem... have you restarted since the Qt update?

Also: there was no need to rebuild a custom-built PageEdit just because your system Qt5.5.x updated. Qt5.15.x are backward compatible with each other. My current PageEdit was built using the system Qt5.15.2 and it's still working fine with the system Qt5.15.5.

I hadn't noticed that Arch hasn't updated their repo version of PageEdit yet. I just flagged it as out of date.

Yes, I have.

I rebuilt PageEdit because the previous version didn't start and I wanted to see if I made a "new" version with the "new" libraries the issue was fixed. But not.

[DiapDealer]

Do you happen to still have a repo version of PageEdit in /usr/bin?

[DiapDealer]

If that's not the problem, I'm not sure what it may be, as I was able to rebuild PageEdit with Qt5.15.5 with no issue.

[KevinH]

Perhaps Qt libraries are out of sync. Mixed pieces with mainly Qt5.15.5 but some other version of QtWebEngine? Or missing QtWebChannel or something so build won't load proper lib?

No, there is not any version of PageEdit in /usr/bin.

I think it must be something of that, because otherwise it wouldn't be giving me the message:

Cannot mix incompatible Qt library (5.15.4) with this library (5.15.5)

But I can't see why is this producing, since I updated the full system with

sudo pacman -Syu

[RbnJrg]

I found the solution. I post this because maybe someone else in the future has the same issue. The problem was with the library "qt5-styleplugins" from the AUR repository, so to solve the thing I had to rebuilt qt5-styleplugins with:

yay -S --rebuild qt5-styleplugins

I didn't think that an AUR-package can have this kind of impact on non-AUR-applications.

[KevinH]

That is news to me. Never even heard of that package. It is not part of official qt5 as far as I can tell. But pinned in it is this:

Quick reminder: Qt 5.15.5 has been released; Users of this package will need to rebuild qt5-styleplugins (yay -S --rebuild qt5-styleplugins), otherwise Qt applications will crash.

The pkgrel of this package has been bumped so this should be done automatically by your AUR helper.

[DiapDealer]

That particular package interacts with the system Qt5, though. So any Qt5 program was likely trying to load incompatible an style plugin when launched.

I use the aur sparingly for just that kind of issue (not that I avoid it altogether, mind you).

[RbnJrg]

Well, I don't know if this is a bug only for my building of PageEdit under my ArchLinux or if is a bug for the Linux version in general.

I built PageEdit with Qt 5.15.5 and it works fine when is opened via Sigil. But when I open PageEdit as a standalone program, and I want to paste text, nothing happens. I can't paste nor formated text nor text without format.

Can anyone test this to see if something with my particular building of PageEdit or if it is a bug for the linux version?

[KevinH]

You need to open an epub or xhtml file in standalone PageEdit using its menus in order to have something to paste into.
