Hi Dominik,
there are two issues in what you describe
1. "There was an error loading the configuration dialog for this style:
Unknown error."
2. QStyle::SH_Widget_Animate
The first problem is that with kf5, the style configuration kcm expects
a libkstyle_oxygen_config.so *plugin* for this configuration, whereas it
was "kstyle_oxygen_config.so" in kde4 times.
now, as the error message indicates: plugins should not start with "lib"
and thus, oxygen still installs kstyle_oxygen_config.so only
so that the ill-named plugin is not found, and you get the error dialog.
To fix,
- either we fix the kcm by changing the looked for plugin name (by
removing the lib prefix)
(I think it was added in the first place due to the lack of replacement
for kde4_add_plugin)
- I re-add the lib prefix to the config plugin name installed by oxygen.
I'd vote for the first solution, but this requires kde wide agreement.
For the second issue,
QStyle::SH_Widget_Animate is set to false not in oxygen style but in
KStyle by itself.
This is unrelated to the style configuration.
I am not too inclined to set it to true, since I am absolutely unclear
what this style hint is meant for. Can someone explain ? Notably, I
don't think it should be set to true for _all_ widgets, since most
widgets are already animated internally by oxygen (and thus should not
be by the app), though it indeed should return "true" for
KMessageWidget, which is not animated internally.
So: should I enable the flag only for widgets that oxygen does not
animate itself ?
Is that the intended purpose of the flag ?
Can someone explain ?
Many thanks in advance,
Hugo

Hi,
in KDE4 times we had e.g. in KMessageWidget:
if (KGlobalSettings::graphicEffectsLevel() &
KGlobalSettings::SimpleAnimationEffects)
{
// do animation
}
Seems this was dependent on the style but read from some config value that was
set through the kcm 'style', clicking "Configure" next to the oxygen widget
style.
This configure button was not available for all styles.
In KF5, this became:
if (style()->styleHint(QStyle::SH_Widget_Animate, 0, this))
{
// do animation
}
Using the Oxygen style, this currently returns false. The configure button
only launches an error message saying
"There was an error loading the configuration dialog for this style: Unknown
error."
At the same time, I get this output on the console:
kcmshell5(13712)/(default) findLibraryInternal: plugins should not have a 'lib'
prefix: "libkstyle_oxygen_config.so"
The config dialog never shows then.
Is there a way to enable animations so that
style()->styleHint(QStyle::SH_Widget_Animate, 0, this)
returns true?
Greetings,
Dominik
