I suspect that space is for expanders, not icons. You could get rid of
it by instead using a TreeView and a ListStore, or by setting
ShowExpanders to false.

That's funny because I did exactly the same thing in the meantime. But I can
not confirm the icon-space problem. As a first step, this solution is good
enough for me...

Yes, This is what I have used, too. (Especially http://www.mono-

Yes, thanks a lot!

Newbie tip: GTK# Primer

2009-11-25T10:18:43Z

Even after browsing the various materials about GTK# online, I have
found it useful to read the two GTK# chapters in the book "Mono: A
Developer's Notebook".

And I got this tip my lurking in IRC channels like #mono and #gtk+ and
#gtk# on irc.gnome.org. Although the #gtk# channel is kind of empty.

Hope that helps,

-Chuck

Hi Martin,

I'm also a GTK# newbie and working on the same thing. So this could be
the blind leading the blind, but here we go anyway:

For the list of files, I used a Gtk.NodeView. Overall it works well,
but on the downside, NodeView reserves some space for an icon that I'm
not currently using.

In the long run, my left nav column may become a VBox containing the
NodeView and other things. You can put whatever you want inside a
VBox.

Both of these are described if you poke around
http://www.mono-project.com/GtkSharpTutorials

I hope that helps,

Exclusive button group (vbuttonbox)?

2009-11-25T04:22:52Z

Hello,

first of all, I'm very new to Mono/MonoDevelop/GTK#, and this is certainly a
typical newbie question.

I would like to have a the following in my main window:
- a notebook widget on the right
- a kind of navigation bar on the left, which selects the displayed notebook
page.

For the navigation bar, I chose a VButtonBox. My problem is now that I would
like to have exclusively checkable (toggle) buttons in the VButtonBox. I guess
something similar is used in the Evolution mail client in order to switch
between Mail, Contact, Kalendar, and so on.
(I think Qt has a QButtonGroup and/or QGroupBox which does exactly what I
want.)

So far, I only managed to get a VButtonBox with "normal" buttons (with the
MonoDevelop GUI designer) or - only manually - with toggle buttons ( [...]
vbuttonbox.Add(new Gtk.ToggleButton("Test")); [...] ), but these buttons are
not exclusive.

Or am I on the wrong track? How can I come up to this kind of navigation bar?

Thanks a lot
Martin

Gdk.Pixbuf.FromDrawable broken?

2009-11-20T15:26:50Z

Hi,
i have little problem with getting a pixbuf from a widget.

So with the attached Code, i'm able to get a Gdk.Pixbuf from a widget, but when i show it in a Gtk.Image it looks "broken".
I googled a lot in the last few days, but i'm not able to find a solution.

I Uploaded a file that you can see what i mean.

Thank you!

Gtk.Button btn_click = new Gtk.Button(Gtk.Stock.Add);
Gtk.Button btn_src = new Gtk.Button(Gtk.Stock.Copy);

The mono-packagers-list would probably be the place to discuss. I'm
not sure who builds for Windows, but Andrew Jorgensen handles the Mac
builds.

Also, after discovering that the Mac Mono installer had removed icon
themes to save space, Aaron Bockover put together a compact Gnome
Tango icon set for Banshee, which you can find in the banshee source
tree. This would probably be a good starting point.

Make an app appear fully "native" on all platforms isn't really
possible for any toolkit to do completely automatically, since all
platforms have unique aspects. If you want to fit in well, you're
going to need some platform-specific code in places. In MD we have a
platform abstraction and runtime checks to handle platform-specific
things.

That said, there's certainly a lot that GTK# could do to help, in the
form of platform API wrappers for thing like the Mac dock icon, Mac
app events, Mac main menu, Windows 7 jump lists, all platforms' native
file dialogs and recently-used- file lists, etc. It might make sense
to pull this sort of code out of apps like MD, banshee, tomboy etc,
and put it in re-usable libraries, maybe something like
Gtk.Platform.Windows, Gtk.Platform.Mac etc.

The default theme shipped with GTK# for Windows uses the Windows theme
engine to draw parts, and looks pretty good, so I'm not sure why
you're having problem with that. The Mac theme isn't so
native-looking, but we went with something that looked nice and
sort-of fitted in with the Mac colours.

Else

End If

desktop.Init(Me)

Me.SetPosition(Gtk.WindowPosition.Mouse)

Me.DoubleBuffered = True
Gtk.Window.SetDefaultIconFromFile(My.Application.Info.DirectoryPath + MySep + "Icon.ico")

AddHandler MyBase.ButtonPressEvent, AddressOf MouseBtnDown
AddHandler MyBase.KeyPressEvent, AddressOf KeyPress

MyTimer.Interval = 50
MyTimer.Start()

When I click with mouse on window application don't detect mouse event. Keyboard event works well.

New Tooltip API Crashes

2009-11-07T12:36:47Z

Is anyone using the new tooltip API in Gtk? I've been working with it the last several days and while I love the API, it seems to be pretty unstable. I keep getting AccessViolationExceptions from the gtk+ libraries, especially when I use the QueryTooltip event on a TreeView. Even the simplest implementation of QueryTooltip that just sets the Tooltip.Text seems to cause problems. The crashes don't seem to follow any pattern. Sometimes they'll occur right away and other times they'll take several minutes. I've also confirmed the same issues with another developer in my office who has experienced similar problems. Has anyone else noticed this? For reference, we're both using XP machines and currently running our Gtk-sharp applications on the Microsoft runtime (we also need to test on Mono and alternate platforms, but we aren't there yet - and if the problems are with gtk+ I don't see the .NET runtime as contributing anyway).

Re: Gtk# on the .NET Framework

2009-11-03T13:55:59Z

Hello,

thanks for your reply.

The msi you mentioned is already installed. As fas as I know you can't even add the "gtk-sharp" reference to your VS project without it. Native GTK+ applications work flawlessly on the systems and so do GTK# applications when run using mono. GTK# applications will also compile using the c-sharp compiler which comes with the .NET framework. The compiled assembly just won't execute using the .NET runtime, but it will do so on the Mono runtime.

Andre.

Hello,

It should work. There is an 8 MB install for Windows, which is available here:
http://ftp.novell.com/pub/mono/gtk-sharp/gtk-sharp-2.12.9-2.win32.msi

no.human.being wrote:

Hello Mono community.

Just wanted to get into Gtk#, since it looks so much better than SWF and feels much more mature and standard-compliant.

However I could not get it to run on the .NET Framework. I use Visual Studio 2008 to compile my binaries and use Gtk# from C#. The .NET Compiler compiles flawlessly and I can run the resulting executable using the Mono runtime (tested on version 2.4.2.3). However, the compiled .NET assembly does not execute on the .NET CLR. Even the following simple code is not running on .NET. When run in "debug" mode, it throws a "System.TypeInitializationException" when the Init() method of Gtk is called. When run in "release" mode, the .NET CLR crashes hard with a protection fault.

class Test
{
static void Main(string[] args)
{
Gtk.Application.Init();
}
}

Hello,

It should work. There is an 8 MB install for Windows, which is available here:

At the GNOME summit two years ago, Mike Kestner and I added a makefile
target to gtk-sharp (win32-installer) to allow merge modules to be
built. This target still exists, and all you need to do is run `make
win32-installer` from a fully built gtk-sharp win32 build to produce a
gtk# msm.

The idea at the time was that Medsphere (who I was working for at the
time) would distribute gtk+ merge modules, and those two combined could
provide the complete gtk# stack. Now, I'm no longer employed by
Medsphere, so I'm not sure if they still release updated merge modules
along with the general gtk-sharp installer. Perhaps someone at
Medsphere could speak to this?

Hope this helps,

-Brad

This refers to the location of the exe. It can be 2.8 or 2.12. Just give here the location where you keep the installation package of GTK#. The installation of the GTK# will be done by the WIX setup that you are creating.

you can launch multiple number of installers from a WIX project. even I am using 2 from my installer, GTK# and Mono.

the following custom action triggers the installation:

You can refer WIX tutorial for further assistance.

Question about CellRendererSpin

2009-10-26T08:11:46Z

Hi,

I have a CellRendererSpin ui component in my treeview. If possible I want to pick up the signal generated when the value in the spinbutton is changed and use it to dynamically alter a drawing based on the current value of the spinbutton. At present the drawing is changed when editing the value is complete as I have placed that code in the cell Edited signal handler. I cannot see how to attach a handler for the ValueChanged signal on the spinbutton in the treeview. So can someone tell me how to do this or even if its possible.

thanks

Alan

I disagree. Gtk# is a set of bindings for (among other things) GTK+.
It is more important that those already familiar with GTK+ know what
things are named than it is that people coming from a different
toolkit altogether know what things are named. I can understand your
position, but you are learning a new toolkit; it would not make sense
for those who are not learning a new toolkit to have to "speak two
languages" when using the same thing.

Yeah, data binding in Gtk# is a pain. I have written a custom TreeModel

which can be used to display any IList (DataView with columns, Arrays,
ArrayLists etc.), but as there appeared to be very less community
interest and there are some more issues with that implementation, it was
never included into Gtk# itself. If you are simply looking for a way to
display and maybe IList data, using that TreeModel might be the best way
to go. I attached the model and a sample application, but you'll have to
change the

Gtk.TreeView treeview = new Gtk.TreeView (dolls); line to
Gtk.TreeView treeview = new Gtk.TreeView (new Gtk.IListStore (dolls));

If you're looking for a complete databinding toolkit, you should use
gtk-databind (http://gtk-databind.sourceforge.net).

I went ahead and committed the patch to the 2.12 branch (the code in
trunk/2.90 is correct). Thank you very much for the fix and the test case.

You can use the Linux dll if you fix the calling convention by using the
gapi-cdecl-insert script in the Gtk# 2.12 repo (or just wait for 2.12.10).
