QT_TO_UTF8 returns a const char * that, in general, shouldn't be stored.
This is because QT_TO_UTF8(str) expands to str.toUtf8().constData():
toUtf8() returns a QByteArray, and constData() the pointer to its data
which is only valid until the QByteArray goes out of scope, which is
immediately after the call.
The original code that is changed here only works because in all of the
situations, the object that is stored to is actually a std::string that
gets constructed implicitly, so the constData() pointer is valid long
enough for the std::string constructor to copy the data.
The issue is that any "... = QT_TO_UTF8" code *looks* unsafe, and may
lead new or unfamiliar contributors to assume that they can also use it,
only to do "const char *... = QT_TO_UTF8(...)" which is dangerous.
Additionally, it introduces an unnecessary round of implicit conversions
and copies when QString.toStdString() already exists and copies into the
string buffer directly.
There is a Qt bug introduced around Qt 6.8.3 that causes the application
to hang when double clicking the sources list and the Windows setting
'Snap mouse to default button in dialog boxes' is enabled. Work around
this by using a timer if the setting is enabled.
For phase 1 of the plugin manager, the ability to toggle off/on plugins
to be loaded at launch is provided.
This commit adds a new Plugin Manager dialog which can be accessed from
the Tools menu, which shows a list of all installed 3rd party plugins
with a checkbox to toggle them off or on. If a change is made, the user
is prompted to restart OBS. To allow this, the plugin manager uses a
json based config file stored in the OBS config directory. Additionally
for sources in the source tree, a sample UI has been provided that
indicates any sources whose parent module is disabled, by turning its
title red.
Effectively reverting 4e97b1bb30, this
removes a hack that added additional spacing as scrollbars would go over
content due to a Qt bug. This bug appears to be fixed, as the described
behavior is no longer observed. As such, the additional spacing is no
longer needed (and only looks out of place).
