Gambas 3.8.0

What's new

Here are the main changes in this new version:

  • The text editor has been entirely rewritten in Gambas. It is located in a new component named gb.form.editor. That way, GTK+ programs now have a text editor with syntax highlighting for free.

  • Support for QT5. The new gb.qt5, gb.qt5.opengl and gb.qt5.webkit components have the same interface as the QT4 components.

  • Automatic support for KDE & Unity tray icon DBus protocols. Just use the TrayIcon class as before, and the new protocol will be automatically used if a DBus system tray icon is detected. Otherwise, the old X11 protocol is used.

  • Important bug fixes in UTF-8 string handling.

  • Searching inside native arrays is faster.

  • The SQLite3 driver has been rewritten and is faster now.

  • And of course tons of bug fixes...

  • Don't crash when a constant is the void string.

GB.DBUS

  • A class inheriting DBusVariant can be used as DBus method return value.

  • Add DBus.Raise() and DBus[].Raise() to raise signals. At the moment, there is no difference between the two methods, as there no mean to indicate the sender raising a signal. I don't know yet how DBus decides which service sends a signal!
