pedrolcl / drumstick Goto Github PK

The back-end plugins may have a function to store the settings, without needing the help of the configuration dialogs provided by drumstick::widgets. This is needed to store a full set of settings in RT projects, like VMPK.

public slot:
    void writeSettings(QSettings *settings);

This method would not be part of the interfaces before Drumstick-3, and could be called only by QMetaObject::invoke().

• Bump version
• Update documentation
• Update web site
• Check backwards compatibility

The Windows RT Input backend does not support sysex events.

PR #20 shows that the current workflow (building and testing only on Linux) is not enough.
Another build&test workflow for Windows should be added, using MinGW and/or MSVC.

I'm struggling to compile this on Arch Linux against Qt6. As soon as I run cmake with -DUSE_QT=6, make VERBOSE=1 fails with the following errors:

Interestingly, version 2.0.0 with d2c95011c90ebacd168b74becf6c1ac83054f910 backported fails with the same error. In January, this built without problems on Arch. So I have a feeling that it could be related to the update to Qt 6.5.1. In January, this was still 6.4.1.

Do you have any idea what could cause this?

While processing library/alsa stuff, new drumstick sources (2.8.0) fail to build here (gcc 11.2.0, x86_64), with multiple "macro names must be identifiers" errors (see attached full log of a failed build).
BuildError.txt.

By looking at one failed command line, I noticed a definition looking suspect ("-D-DRTKIT_SUPPORT"): it looks like a spurious "-"...
Indeed, changing the line 26 in the CMakeLists.txt file for library/alsa from "$<$BOOL:${HAVE_DBUS}:-DRTKIT_SUPPORT>" to "$<$BOOL:${HAVE_DBUS}:DRTKIT_SUPPORT>" (ie removing the stray "-" before DRKIT_SUPPORT) it completely fixes the issue.

https://doc.qt.io/qt-6/signalsandslots.html#signals-and-slots-in-qt-based-libraries

The public API of Qt-based libraries should use the macros Q_SIGNALS and Q_SLOTS instead of signals and slots. Otherwise it is hard to use such a library in a project that defines QT_NO_KEYWORDS.

To enforce this restriction, the library creator may set the preprocessor define QT_NO_SIGNALS_SLOTS_KEYWORDS when building the library.

While the SettingsFactory class has an static function SettingsFactory::setFileName(), it does not provide a SettingsFactory::fileName() function to read the static member. While we are on it, provide also a SettingsFactory::format() function as well.
