Gtk# 2.99.1 - 2013-09-23
|
||||
===============================================================================
|
||||
|
||||
Gtk# 2.99.1 is the second release of C# bindings for GTK 3.x. This is a beta
|
||||
release, primarily intended for applications developers who want to start
|
||||
porting their application to GTK 3.x.
|
||||
|
||||
This version of Gtk# provides bindings for the API exposed by these libraries:
|
||||
* cairo 1.10.0
|
||||
* glib 2.28.0
|
||||
* pango 1.28.3
|
||||
* atk 1.32.0
|
||||
* gdk-pixbuf 2.22.1
|
||||
* gtk+ 3.0.0
|
||||
|
||||
There is no API stability guarantee for now, but we will try to keep breaking
|
||||
changes to a minimum.
|
||||
|
||||
This version of Gtk# can be installed in parallel with Gtk# 2.x, and should not
|
||||
have any impact on applications using Gtk# 2.x.
|
||||
|
||||
New features and enhancements
|
||||
-----------------------------
|
||||
|
||||
* Support for async/await in the GTK main thread
|
||||
|
||||
If you use the async/await keywords in your Gtk# app, things will now
|
||||
work as expected with the GTK main thread. For example:
|
||||
|
||||
static async void DoWork () // called in the GTK main thread
|
||||
{
|
||||
// Do some stuff with the UI...
|
||||
label.Text = "Starting Work";
|
||||
|
||||
// Run something asynchronously, UI is not frozen
|
||||
int res = await DoLongOperation ();
|
||||
|
||||
// Do some more UI stuff, it'll run on the GTK main thread
|
||||
label.Text = "Work done";
|
||||
}
|
||||
|
||||
* gui-thread-check profiler module
|
||||
|
||||
This mono profiler module can be used to check if a GTK# application is
|
||||
trying to invoke gtk or gdk methods from a thread which is not the main
|
||||
GUI thread.
|
||||
|
||||
To use it, run your application with the command:
|
||||
|
||||
mono --profile=gui-thread-check yourapp.exe
|
||||
|
||||
If the profiler is properly installed, you'll see an output like this:
|
||||
|
||||
*** Running with gui-thread-check *** GUI THREAD INITIALIZED:
|
||||
*** 2861676352
|
||||
|
||||
While the application is running, if the profiler detects a non-gui
|
||||
thread invoking gtk methods, it will print a warning message together
|
||||
with a stack trace. For example:
|
||||
|
||||
*** GTK CALL NOT IN GUI THREAD: Widget.gtk_widget_get_parent
|
||||
Widget.get_Parent
|
||||
SomeWidget.DoSomething
|
||||
BackgroundWorker.OnDoWork
|
||||
BackgroundWorker.ProcessWorker
|
||||
|
||||
* cairo: Rework the handling of native resources, to reduce memory leaks.
|
||||
In general, the caller is responsible for disposing IDisposable objects
|
||||
returned from any method.
|
||||
|
||||
* cairo: Add mechanism to debug missing Dispose calls, enabled by setting a
|
||||
new MONO_CAIRO_DEBUG_DISPOSE environment variable.
|
||||
|
||||
* Provide and use an XML schema definition to validate GAPI XML files.
|
||||
|
||||
* Use generic collections in the generated code, in custom code and in the
|
||||
generator itself.
|
||||
|
||||
* Improve handling of command-line parameters in the generator.
|
||||
|
||||
* glib: Install interfaces before they are initialized, to match the behavior
|
||||
now required by glib 2.36 and above.
|
||||
|
||||
Changes
|
||||
-------
|
||||
|
||||
* Generate all interfaces with the "I" prefix, to match .NET coding
|
||||
convention. For example, Scrollable is now IScrollable.

||||
* gdk: Remove AddClientMessageFilter method from Gdk.Display and Gdk.Global
|
||||
* cairo: Add SetSourceColor method to Cairo.Context.
|
||||
* gio: Correct return types for methods returning GList*, in various classes
|
||||
* gio: Rename Content class to ContentType and adjust method names

|
||||
adjust their names and fix the return types
|
||||
* gio: Move the scheduler-related static functions into IOSchedulerJob
|
||||
* gio: Move ErrorQuark method to GioGlobal
|
||||
* gio: Create IOError class, with FromErrno and FromWin32Error methods

* gio: Rename the Dbus class to DBus, to have consistent capitalization
|
||||
* gio: Rename all GDbus* properties to GDBus*, with correct capitalization
|
||||
* gio: Rename the DBus.AddressGet* methods to DBus.Get*
|
||||
* gio: Move static methods from Simple to SimpleAsyncResult class
|
||||
* gio: Hide GioGlobal.RegistryBackendGetType method
|
||||
* gio: Mark the Seekable interface as consume-only
|
||||
* gio: Correct GSettings.GetStrv and SetStrv values to be string[]
|
||||
* gtk: Mark the whole Style class as obsolete
|
||||
* gtk: Fix return types for several methods: GtkCellArea.GetFocusSiblings,
|
||||
GtkMenu.GetForAttachWidget, GtkWindowGroup.ListWindows
|
||||
* gtk: Make the Group property for Radio* widgets a properly typed array
|
||||
* gtk: Fix return types for IterList* methods in WidgetPath
|
||||
* gtk: Change the second parameter in AccelMap.LookupEntry to be an out param
|
||||
|
||||

|
||||
---------
|
||||
|
||||
* generator: Add validation check for return values that are arrays
|
||||
* cairo: Fix rectangles returned by StrokeExtents and FillExtents methods
|
||||

|
||||
