I suspect you will be OK but this is one of those occasions where it is
probably best to try it and see. You will certainly run into problems
however if you fork() from the thread in which GTK+ is running after
calling gtk_main().

To fork() after the main loop is running I always start a new thread to
dispatch the new process and fork() from that. Of course, that also
means (since it will thus become a multi-threaded program) that you can
only call async-signal-safe functions after the fork() and before the
call to exec*(). This in turn means you must call all non
async-signal-safe functions which are needed to prepare for an exec()
before the fork() and not after, but given that all modern fork()
implementations provide copy on write, that is not problematic. (You
probably know all that but I thought it worth mentioning.)

Glibmm, Giomm and daemon program

2009-11-08T04:16:03Z

Hello!

I'm working on daemon program, which use Glibmm and Giomm. I have to call few functions from Glib and Gio before I run fork(), so at the beginning of main function I call Glib::init() and Gio::init():

main()
{

Glib::init ();
Gio::init ();

// Here I use Glib::OptionContext etc

fork ();

// rest of code

}

I'd like to know if Glib::init() and Gio::init() do some "weird" things (like opening files) in background, which may cause problems, when I fork program.

Bye!

If you mean that you want to access polymorphic c++ objects in C code
(that is, access them when actually programming in the C language) then
no. You would have to use GObject polymorphism throughout to do that,
which is entirely implemented in C.

But I am not sure that you do mean that as you can of course program
GObject code in C++ as well as C, and if you are programming in C++
then you can extract your polymorphic object in the way I have
mentioned. Thus if you wrote your implementation of g_object_new()
typed for your custom POD GObject (you can give any struct its own
GObject type with G_DEFINE_TYPE), you could (unbeknowst to GObject)
have a c++ polymorphic object standing behind it. At the end of the
day, you can cast to anything.

I have no idea how that interacts with glade I am afraid. Quite
probably it doesn't, in which case you can't do what you want.

I'm trying to (but I don't know if it's possible) to make polymorphic
c++ objects usable from
GObject in C.
I'm not sure if it's possible. Anyway, what I'm trying to do is to
test that Widgets in glade
written in C++ are displayed with their properties, and I don't know
if it's a requirement
that g_object_new from C works to create my c++ type. Is it needed the
layout compatibility?
or is there any trick?

I am not entirely sure what you are trying to do, but if your
MyCppClass is a POD (in particular, it has no virtual functions) then
you can derive from that with a child class with virtual functions.
Note however that you must use a static_cast to go from MyCppClass to
its child and not a reinterpret_cast, because they will likely have
different addresses because of the child's vtable. static_cast will
automatically provide an address offset when casting (it is required to
do so by the standard) and reinterpret_cast will not.

In other words, you could have MyVirtualClass as a child of MyCppClass,
and do a reinterpret_cast from the GObject parentclass to MyCppClass
(if MyCppClass is a POD), and then a static_cast to MyVirtualClass. As I
say, though, I do not know if that is in fact the kind of thing you are
after. As I also say, the point to always be aware of is that
reinterpret_cast<void*>(my_virtual_class) and
reinterpret_cast<void*>(static_cast<MyCppClass*>(my_virtual_class))
are likely to yield different values - you can test it with a std::cout
if you are interested. Whethere it does or not depends on where the
compiler puts the vtable.

Calling Gtk::ToggleToolButton's set_icon_widget() multiple times

2009-11-07T06:25:50Z

Hi all,

I'm new to this mailing-list (and quite new to Gtkmm programming too),
but I joined because I have a problem to which I couldn't find an answer
through your mailing-list-archives and best friend Google.

My goal is to add a Gtk::ToggleToolButton to a Gtk::Toolbar (this
works). The Gtk::ToggleToolButton should show icon #1 in its non-active
(raised) state and icon #2 in its active (pressed) state. Here's how I
tried to accomplish this in class Foo:

----------------------------------------------------------------

/* Class Foo's private variables */
Gtk::ToggleToolButton mToggleToolButton;
Gtk::Image *pImage;

/* Class Foo's constructor */
Foo::Foo()
{
// In this constructor the ToggleToolButton is successfully set to have
the default icon
Glib::RefPtr<Gdk::Pixbuf> im =
Gdk::Pixbuf::create_from_file("path_to_icon_1", 22, 22, true);
pImage = manage(new Gtk::Image(im));
mToggleToolButton.set_icon_widget(*pImage);
mToggleToolButton.signal_toggled().connect( sigc::mem_fun(*this,
&Foo::on_toggletoolbutton_toggled) );
}

void Foo::on_toggletoolbutton_toggled()
{
if ( mToggleToolButton.get_active() )
{
// Here I try to replace the ToggleToolButton's icon
Glib::RefPtr<Gdk::Pixbuf> im =
Gdk::Pixbuf::create_from_file("path_to_icon_2", 22, 22, true);
pImage = manage(new Gtk::Image(im));
mToggleToolButton.set_icon_widget(*pImage);
}
else
{
// Icon #1 again
}
}

----------------------------------------------------------------

I've tried the above with and without the Gtk::manage() function, both
with no luck: when the ToggleToolButton is toggled for the first time
after construction, icon #1 is removed as expected but not replaced with
icon #2. Maybe needless to say, but when the ToggleToolButton is toggled
for a second time or more it remains without icon.

What am I doing wrong here? Or can Gtk::ToggleToolButton be only set to
have an icon once? Hope you can help me out!

Regards,
Ruud

Is there any problem to create C++ classes from C (Gtk::Window, etc) ?

2009-11-07T05:16:18Z

Hello. I have a very technical issue. If some expert could tell me if
it's wrong.
The issue is that I can do this:

GObject * obj = G_OBJECT(g_type_new("MycppClass", NULL));

as long as MyCppClass has this layout:

class .... {
GObject parentclass;
...
};

If I define a virtual function, it won't work anymore. Is there any
workaround to this?
Because in the c gobject manual it says that the layout must be like
that, in order
for GObject to work, but for C++ it's very inflexible.

Is there any well-known solution to workaround the virtual table issue
and keep my classes
working in C? Thanks.

Maybe I can try some of the above. I have a doubt about wrapping
Gobjects from c++ (for now I'm trying my own implementation of
Glib::Object too)

I have

class glib::object {
GObject parent_class;
public:
....

};

class MyClass : public glib::object {

....
};

My problem is that if I make my destructors virtual (which I do want
to do), then:

GObject * obj = G_OBJECT(g_type_new(g_type_from_name("MyClass"), NULL));

G_OBJECT casting won't work. I think it's because with a vtable, the
layout for the type changes, but I don't know how to workaround this
and
keep G_OBJECT macro working, which is very important for C
compatibility and exposure.

Gobject and c++ types.

2009-11-05T17:41:30Z

---------- Forwarded message ----------
From: Milosz Derezynski <internalerror@...>
Date: 2009/11/6
Subject: Re: Gobject and c++ types.
To: Murray Cumming <murrayc@...>

Just reading this and thinking about it, it occured to me that there is a rather uncumbersome way, similar to propertyproxy, by which we can have automatically C and C++ signals

First, we'd need a Glib:Signal (aka Glib::Object::Property), templated, so you e.g. do:

typedef Glib::Signal<void, std::string, int> MySignal1 ;

then...

class MyNeatClass

{

/* ...yaddayadda ... */

MySignal1 m_mysignal_1 ;

} ;

ow there are the next 2 important steps.

First, in order to access the actual signal we can do e.g. this:

class MyNeatClass

{

MySignal1::Signal&

signal_get_some_data()

{

return m_mysignal_1.signal() ;

}

Since Glib::Signal<> looks inside prolly like this:

template <typename RV, typename T2, typename T3>

class Glib::Signal

{

public:

typedef sigc::signal<RV, T2, T3> RealSignal ;

private:

RealSignal m_real_signal ;

public:

RealSignal&

signal() ;

};

sssssssssssoooooooo..... so far it should be clear. So far it's just a small wrapper around sigc signals.

Now comes the interesting part though: Let's look at the constructor.

class Glib::Signal

{

Glib::Signal(

const std::string& name

, Glib::Signal::RunType type (i.e. Glib::Signal::RUN_FIRST or Glib::Signal::RUN_LAST)

) ;

}

so now in our instance of MyNeatClass, we have:

MyNeatClass::MyNeatClass

: Glib::ObjectBase("MyObject")

: m_mysignal_1("get-some-data", Glib::Signal::RUN_FIRST)

{

}

So far, so good. With only a little overhead in complexity of the code we were able to install a C and C++-signal at the same time. Now Glib::Signal just needs some logic to, when ::emit() is being used, the emission goes out through both subsystems, or if someone uses g_signal_emit on that signal (doable with GObject voodoo).

But, issues remain.

For one, the C signal registration requires a return GType and a VA list of return types. Now this is not a big problem since already when using our Glib::Signal template we'll know how many types i.e. signal arguments we'll be dealing with. So, one could just specify these here as well:

m_mysignal_1("get-some-data", Glib::Signal::RUN_FIRST, G_TYPE_STRING, G_TYPE_INT)

(The constructor obviously needs 2 more args but since it's the RV+2args template that is of course logical).

Ok but what does that give us? Really not much at least as far as typesafety goes. YOU just have to make sure that the G types you specify correspond to the C++ signal's types. This is nut-to-crack #1.

Nut-to-crack #2 is a bigger problem. The GSignal signal requires a marshaller, and depending on what you want to pipe through that signal, you have to generate one first with glib-genmarshal. Now this is a REAL problem.

Now , I'm not even sure that this should be followed up upon, but I just wanted to show that it is in fact not that impossible, and if you can live with a few irks even quite doable.

class MyClass : Glib::Object

MyClass::MyClass
: Glib::ObjectBase("myclassname")
{

will also register a derived GType.

Gobject and c++ types.

2009-11-05T05:02:54Z

Hello. I'm trying to implement a system that works in a perfect way
with the GObject C library, so that things are easier to integrate
c++ classes in tools that use the metadata from GObject, like glade.

Maybe when I finish this, I could send it here to be able to integrate it
with glibmm and improve the object model.

My system must allow to register (yes, with macros, no other way) properties,
gobjects and signals, etc. So for now, what I can do is the following:

class MyClass : public glib::object {

};...

GLIB_REGISTER_CLASS(MyClass, glib::object);

int main(int argc, char * argv[])
{
MyClass * c = (MyClass *)g_type_new(g_type_from_name("MyClass", NULL));
c->method();
}

My problem is that now I want to install properties and use them. In
order for properties
to work well in C programs (like glade), they should be able to be set
from GObject:

g_object_set(G_OBJECT(c), "Prop", value);

My problem is that G_OBJECT macro fails with the following:

GLib-GObject-CRITICAL **: g_object_set: assertion `G_IS_OBJECT (object)' failed

But if I query this:

g_type_is_a(g_type_from_name("MyClass"), G_TYPE_OBJECT)

it returns 1. So I want to know why this fails in order to solve the
problem. I'm stuck here for now.

I use InstanceInit from GTypeInfo to call the c++ constructor, and
class_init from GTypeInfo to install properties.
But the casting fails and I don't know why. Thanks in advance.

It doesn't make sense to me either. What I would suggest is that you
guide yourself from the example that you hacked. On this system the
example works fine (with tabs, etc.) as you also want. I can't tell
definitely but, once more, my guess would be that if you handle key
presses, I don't think that you need to pay special attention to the tab
key. This is just a guess as I'm going by how the original example
works on this system.

Hi Jose,

you will find the hacked treeview from the gtkmm examples in the attachment.

Basically all I did was attaching on_key_press() to signal_key_pressed.
Funny thing tough: If I add the column

m_TreeView.get_columns();

to the attached function, everything works as I would expect it.
It just does not seem to make any sense to me.

Many thanks for your effort.

Yes, and I use it in Glom if you want to see an example. I'm sure I've
mentioned this before.

I'm not confident that you'll find it easy to use as a C API that
requires copying of source code.

Maybe if you provide a minimal test case we can run it and see what the
problem is. My guess would be that editing should work out of the box
(without the need for special code). From reading the book, I get the
impression that if you use the [insert/append]_column_editable() methods
of the TreeView things should work correctly, but I could be wrong.

Re: Libegg - eggtoolpalette.h

2009-11-04T11:04:04Z

Excellent! I saw the screenshot in
http://bugzilla-attachments.gnome.org/attachment.cgi?id=129305
and it is exactly what I am looking for. I am sure more icons will be added by the developer or that there is a way that the users or other developers/programmers can add at will.
What I would like to know now is if all I need to do is to add the source code to my project or if there is something else I should do. I am using Code::Blocks under MS.

Please Murray, give us some input on this matter.
TIA

There's a demo that you can run, in the libegg git module.

Re: treeview Tab control

2009-11-04T09:48:31Z

Hi all,

for the cellrenderer I just found editing_canceled()

here the hack into the editable treeview example from the docs:

bool ExampleWindow::on_key_press(GdkEventKey* event)
{
std::cout << event->keyval << "\n";
Gtk::CellRenderer* r=m_TreeView.get_column_cell_renderer (0);
r->editing_canceled();
}

I get the key value but editing is not canceled when hitting tab in the
first column.
Do I select the wrong renderer?

Re: treeview Tab control

2009-11-04T09:06:25Z

That's exactly what I tried before:

bool gui::key_pressed(GdkEventKey* event)
{
if(event->type == GDK_KEY_PRESS && event->keyval == GDK_Tab)
{
Gtk::TreeModel::iterator iter =
m_refTreeSelection_TreeView->get_selected();

Gtk::TreeModel::Path p;
Gtk::TreeViewColumn* c;
m_pTreeView->get_cursor(p,c);
if(c==m_pTreeView_OPL->get_column(0))
m_pTreeView_OPL->
set_cursor(m_refModel_TreeView->get_path(iter),
*(m_pTreeView->get_column(1)),true);

}
return true;
}

Problem is:
Hittin tab will set the cursors to the second column but the entry in
the editable gets lost. Restoring it to the value stored in the TreeStore.

Therefore I tried to get a hold of the cellrenderer

Gtk::CellRenderer* r=m_pTreeView->get_column_cell_renderer (0);
Gtk::CellRendererText* t=dynamic_cast<Gtk::CellRendererText*>(r);

and tried to emit the changed signal. Sadly the emit() funktion does not exist ;-(
t->signal_edited().emit();

I know this is a bad idea but doing something like this would be much easier than writing my own cellrenderer (I think).
I read something about calling the signal handler instead of emitting the signal myself. But how do I call the signal handler of the celleditable?

Thanks,

Thomas

Thanks for the reply. I remember reading that they removed this feature,
though I wasn't sure exactly what widgets it affected. I don't
understand why they would remove the feature...they could leave it there
but discourage the use of this feature through the HIG if they are going
for a certain consistent look. I really need it in this case since I'm
trying to implement buttons for a script interface that have functions
like play, pause, stop, next, prev, etc. People are very familiar with
the icons from everyday life and react faster to the icons than to
reading the equivalent text.

Re: Gtk::Stock::CANCEL

Unfortunately no.
I have tried every possible avenue, ideas and experiments, but to no avail.

I asked Murray if he would give me some ideas about implementing the
look and style of GNOME themes, but I am still waiting for a response.

As Murray said in his last email, the Gtk+ team decided to remove that
feature to make the GUI more MS like, which I find to be saddening.

Please, please, Jim, if you find a work around, do, let us know. I hope
the GTK+ team is reading these emails and re-implement the choice of
adding widgets to the buttons, thus giving the developers the choice of
the feel and look of his/her applications.

Have a grate day!

Did you ever get a solution to this problem? Even trying some of the
suggestions on this list to your original post, I still can't get a
stock image to appear on any buttons. I can get the text of the stock
button to appear just fine, but never the associated image.

Re: How is it possible to use gtkmm default window frames instead of win32-window frames on XP?

2009-11-04T00:27:25Z

Oh yes, I use an Andora - theme it make my application very "beautiful",
I like it, but the border of window is a XP-Style that not really a best
design :-). But I have seen inside of Andora - theme directory images
for buttons (close, maximize, minimize) of the window-border and thought
that it would be possible to start the application with the theme
specific border, thats the reason because I write at the moment to the
list!!!

You must be referring to themes. I don't know much but searching for
gtk+ windows themes might show some good results. For example, I found
the following link:

Maybe you can create a boarder-less window, then draw your own boarder.
Gtk[mm] has no default boarder however.
