Subject: [PATCH] Do not fully initialize QIconLoader when setting the fallback
theme
We need this because without this patch you get bugs both
if you call QIcon::setFallbackThemeName before creating the QGuiApplication and
if you call QIcon::setFallbackThemeName after creating QGuiApplication
Why do you get a bug if you call QIconLoader::setFallbackThemeName
before creating the QGuiApplication:
* QIcon::setFallbackThemeName calls QIconLoader::instance
* QIconLoader::instance calls QIconLoader::ensureInitialized
* QIconLoader::ensureInitialized calls systemThemeName
* systemThemeName asks the current QPlatformTheme for its
QPlatformTheme::SystemIconThemeName
* But since we're calling this before creating the QGuiApplication
there is no current QPlatformTheme yet, so systemThemeName
is set to empty, which is obviously not what we want
Why do you get a bug if you call QIconLoader::setFallbackThemeName
after creating the QGuiApplication:
* QGuiApplicationPrivate::init calls
QGuiApplicationPrivate::createPlatformIntegration
* QGuiApplicationPrivate::createPlatformIntegration sets the
current QPlatformTheme and at the end of the very same function
uses QIcon::fromTheme
* Since we haven't called QIconLoader::setFallbackThemeName yet
there is at least one icon lookup that doesn't take
the fallback theme we would like to have into account
This patch makes it so calling QIconLoader::setFallbackThemeName
before creating the QGuiApplication works.
The only thing we want to do from QIcon::setFallbackThemeName is set
the internal m_userFallbackTheme, it doesn't care about doing
further initialization of QIconLoader, if it's done, great it's done,
if it is not initialized yet, great it will be initialized later
when someone actually tries to use the QIconloader.
So it's OK for ensureInitialized() to return early if there is no
platform theme yet, because it will be called again later.
Pick-to: 5.12
Pick-to: 5.15
Fixes: QTBUG-74252
