Hello, I'm trying to run the example over a Dell netbook i386 with Ubuntu 10.10 and 8g version 6980... when I try to run the Makefile on the demo directory, I get the following error:

I've been searching around to solve this but I just can't find the error nowhere... Can anybody please help me to solve this??. Thanks in advance.

I'm unable to compile go-gtk on ArchLinux amd64 with gtk+ 2.20 and latest go. I get the following error:

CGOPKGPATH= /home/luka/bin/cgo pkg-config --cflags gtk+-2.0 -Duintptr="unsigned int*" gtk.go
gcc failed:
cc1: warnings being treated as errors

:41:12: error: '_callback' used but never defined

Hi,
this is not really an issue. I'd like to add comments, mostly cut&paste from gtk documentation, to gtk.go so I can read how functions work from godoc documentation. Before starting I was wondering if it is better to break gtk.go into smaller files before doing that or just adding to gtk.go even if it will become a huge file.
What do you think?

I had trouble building GtkSourceView on Win32, so I've forked this repo & removed GtkSourceView. This simplifies the install. See https://[email protected]/ralmoritz/go-gtk.git

I installed go-gtk with goinstall today and it failed to build builder example:

Is the README only?

It says to use goinstall. Is this go 1 now?

I have had go-gtk running in the past using the make file, but know I get an error. What has changed?

The following is the output of: goinstall github.com/mattn/go-gtk/gtk

/bin/bash: === cd /Users/Jim/go/src/pkg/github.com/mattn/go-gtk/glib; bash gomake -f- install

Hi, after downloaded your code and try to install it:

make install

I got this error: No rule to make target "/home/davidhhuan/Go/src/Make.inc"

My platform is: Ubuntu 10.10-i386

I try to modify your the first line of these files: go-gtk/Makefile, go-gtk/glib/Makefile, go-gtk/gtk/Makefile, go-gtk/gdkpixbuf/Makefile, go-gtk/gdk/Makefile,
From:
include $(GOROOT)/src/Make.inc
To:
include $(GOROOT)/src/Make.386
And then make install, it works!

It is an issue or something else in my platform?

Is it possible to get details of an event? I'd like to get the pressed key from a "key-press-event". I see that I can get "something" calling myCallbackContext.Args(n int) but I cannot use it properly.
Thanks

I enter "make example" and it gives me the following:

cd glib && gomake install
make[1]: Nothing to be done for install'. cd gdk && gomake install make[1]: Nothing to be done forinstall'.
cd gdkpixbuf && gomake install
make[1]: Nothing to be done for `install'.
cd gtk && gomake install
cd example && gomake
cd demo && gomake
6l -o demo go.6
too many loads

It seems that there are a few places where "uint" was used, and while this seems to work on Linux, Snow Leopard does not find that type. However, these cases are cases where guint is an ideal substitute. The patch below should make it work correctly:

When in c-gtk I can use WinMain entry point or -mwindows flag.

But don't know how to in go-gtk.

I updated go and know Go-GTK gives the following errors:

Hi,

I haven't got a clue where to start with this issue. Any ideas?

Many thanks,

It's difficult to produce the error.
it happened when I maximum the window then close it.
It only happen occasionally.
One case is:
I'm in the example folder //I can reproduce error in this folder. but can't in the parent folder.
I first run ./demo/demo.exe then close it.
then run ./thread/thread.exe the maximum it then close it.
It'll display infinity errors like this.

$ ./thread/threads.exe

Window hangs until all updates are complete, then refreshes (under ubuntu, this caused the window to go dark for a moment). Previously it updated as messages came in.

I am have aImac OSX 10.7

The building process does not work as gomake is currently not supported and there is no %(GOROOT)/src/Make.inc cannot be found (is not present).

I was using the standard go package from archlinux version 1.

Please update the documentation and make scripts.

I am unable to use something similar to gtk_alignment_new. Am I simply misunderstanding something?

I want to get the signals that GtkTextBuffer sends but I can't :(

Hallo.

I've got the follwoing problem:

$ mogoh@annalee:~/daten/sourcecode/go-gtk$ make install
cd glib && gomake install

I'm using latest releases and I'm not sure if it's a bug or if I'm doing somthing wrong.

and I did hg pull&&hg update for go, so it's not release

I have MinGW environment located at C:\MinGW.
I have go freshly pulled (but at Rev 7300) located at C:\MinGW\go (in MSYS /C/MinGW/go).
I can build go without problems and make small go sample programs with no problem.
I pulled a fresh copy of go-gtk into: C:\MinGW\go-gtk.
I downloaded and unziped gtk+ 2.22 from gtk.org (the bundled one) and put it at: C:\MinGW\gtk+. I put C:\MinGW\gtk+\bin into my PATH (I have tried this in the usual place in System Properties and also from the batch file that starts MSYS).

In MSYS I enter pkg-config --cflags gtk+-2.0 and I get:

Can you see any reason that this is not working? I'm not very familiar with mingw/msys but I have reviewed my steps several times and do not see what I could have missed.

The example notebook has the text "go next" and "go perv".

Here is a patch that changes "go next" to "Next", "go perv" to "Previous", and "demo" to "frame" for the frame text:
http://go.pastie.org/1998271

If you wish to keep "go perv" for humoristic reasons, it's fully understandable.

whenever drag the bar,It'll exit, the output is:

Thanks~

If I read values in a GtkTreeModel in a loop reusing the same GValue the application crashes.
Workaround: use a new GValue each time

Here is the code

package main

import (
"os"
"gtk"
"strconv"
"glib"
"fmt"
)

var store *gtk.GtkTreeStore

func main() {
gtk.Init(&os.Args)
window := gtk.Window(gtk.GTK_WINDOW_TOPLEVEL)
window.SetTitle("GTK Folder View")
window.Connect("destroy", func() {
    gtk.MainQuit()
},
    nil)

swin := gtk.ScrolledWindow(nil, nil)

store = gtk.TreeStore(gtk.TYPE_STRING)
treeview := gtk.TreeView()
swin.Add(treeview)

treeview.SetModel(store.ToTreeModel())
treeview.AppendColumn(gtk.TreeViewColumnWithAttributes("string", gtk.CellRendererText(), "text", 0))    
//populate tree
var iter1, iter2 gtk.GtkTreeIter
store.Append(&iter1, nil)
store.Set(&iter1, "testing")
for i := 0; i < 10; i ++ {
    store.Append(&iter2, &iter1)
    store.Set(&iter2, "testing"+strconv.Itoa(i))
}

//print tree
var iter3, iter4 gtk.GtkTreeIter
var value glib.GValue //CRASH RELATED
store.ToTreeModel().GetIterFirst(&iter3)
store.ToTreeModel().IterChildren(&iter4, &iter3)
for {
    //var value glib.GValue // With a new GValue each time there is no crash
    store.ToTreeModel().GetValue(&iter4, 0, &value)
    fmt.Println(value.GetString())
    if !store.ToTreeModel().IterNext(&iter4) { //finito e non trovato
        break
    }
}

window.Add(swin)
window.SetSizeRequest(400, 200)
window.ShowAll()

gtk.Main()
}

and here is the crash log

Hi,

I tried to compile examples on release.r57.1, but it could not.
I got a error message as follows.

$ cd $GOROOT/src/pkg/github.com/mattn/go-gtk/example/
$ cd demo && gomake
6g  -o _go_.6 demo.go 
6l  -o demo _go_.6
MACHORESERVE too small: 3608 > 3072
make[1]: *** [demo] Error 1
make: *** [all] Error 2

My environment is as follows.

$ 6g -V
6g version release.r57.1 8294
$ sw_vers
ProductName:    Mac OS X
ProductVersion: 10.6.7
BuildVersion:   10J869

When running the twitter example, I see random panics occur.

I have a working demo of go-gtk, but I'm having difficulty producing code that receives text from a dialog box. I want to be able to input text or number data and use as input data. Nothing fancy, just print the request and except the input.

Can you send me a simple example.

On page http://mattn.github.com/go-gtk/ there is in example:
package main

import (
"os"
"gtk"
"path"
)
Which is probably bad and should be:

package main

import (
"os"
"github.com/mattn/go-gtk/gtk"
"path"
)

(gdk gdkpixbuf glib gtksourceview pango compiles fine)

installed dev libs:
sudo apt-get install libgtk2.0-dev

when compiling on debian i386 I'm getting these errors

I hava a little sample program which uses a GtkEntry with a connected "insert-text" signal. The "insert-text" signal has 3 arguments: Arg(1) is an int which I can convert just fine, but Arg(0) is a char*.

How do I convert it to a real Go string?

mynewtext := string(ctx.Args(0)) does only produce a weird rune. I guess I would have to work with C.GoString() and C.to_charptr() as you did in GtkEntry.GetText(), but I can't seem to import "C" without converting my program to a cgo project.

Do you have a plan for handling signals more go-like? Or do you know of a way to convert the string correctly?

Hi, I'm having some problem with go-gtk crashing, this is an example of a crash caused by calling back a function connected to a SourceBuffer: buffer.Connect("modified-changed", callback)
The problem appears in many other cases involving Connect, commenting out the call to Connect removes the problem so I guess the problem could be there. There was no problem before commits about event queue (I wouldn't know which one, I pulled all changes together only recently)

I wrote a simple example that shows the problem when connecting some gtk.Paned to a callback function
it seems the problem appears only if I connect different gtk.Paned to the same function. Although menus don't seem to suffer the same effect.
Here is the example:

package main

import (
    "github.com/mattn/go-gtk/gdk"
    "github.com/mattn/go-gtk/gtk"
)

func main() {
    gtk.Init(nil)
    initGui()
}

func initGui() {
    window := gtk.Window(gtk.GTK_WINDOW_TOPLEVEL)
    window.Connect("destroy", tryquit, nil)

    vbox := gtk.VBox(false, 1) //menubar / main window

    //----------------------------------------------
    // Menubar
    //----------------------------------------------
    menubar := gtk.MenuBar()
    vbox.PackStart(menubar, false, false, 0)

    accelgroup := gtk.AccelGroup()
    window.AddAccelGroup(accelgroup)

    cascademenu := gtk.MenuItemWithMnemonic("_File")
    menubar.Append(cascademenu)
    submenu := gtk.Menu()
    cascademenu.SetSubmenu(submenu)

    menuitem := gtk.MenuItemWithMnemonic("_Open File")
    menuitem.Connect("activate", openFile, nil)
    submenu.Append(menuitem)

    menuitem = gtk.MenuItemWithMnemonic("_Open Dir")
    menuitem.Connect("activate", openDir, nil)
    submenu.Append(menuitem)

    menuitem = gtk.MenuItemWithMnemonic("_Save")
    //menuitem.AddAccelerator("activate", accelgroup, gdk.GDK_KEY_s, gdk.GDK_CONTROL_MASK, gtk.GTK_ACCEL_VISIBLE)
    menuitem.AddAccelerator("activate", accelgroup, gdk.GDK_KEY_s, 4, gtk.GTK_ACCEL_VISIBLE)
    menuitem.Connect("activate", save, nil)
    submenu.Append(menuitem)

    menuitem = gtk.MenuItemWithMnemonic("_Quit")
    menuitem.Connect("activate", func(){window.Hide()}, nil)
    submenu.Append(menuitem)

    cascademenu = gtk.MenuItemWithMnemonic("_Help")
    menubar.Append(cascademenu)
    submenu = gtk.Menu()
    cascademenu.SetSubmenu(submenu)

    menuitem = gtk.MenuItemWithMnemonic("_About")
    menuitem.Connect("activate", showAbout, nil)
    submenu.Append(menuitem)

    panedFF.Pack1(frame(), true, false)
    panedFF.Pack2(frame(), true, false)
    panedFF.SetPosition(400)
    //panedFF.Connect("size_request", func(){savePanedLayout(DFF, panedFF.GetPosition())})
    panedFF.Connect("size_request", openFile)

    panedFP := gtk.HPaned() // file tree | package tree
    panedFP.Pack1(panedFF, true, false)

Compiling tabby with go-gtk I have run into type mismatch issues. GtkResponseType is not being recognized as an int. Any suggestions where this may have cropped up from?

Makefiles don't function for go tip.

This is just an annoyance, I'd expect it to behave like (in C)

gtk_init(NULL, NULL);

which is the same as no arguments.

gtk.go

// TODO
// void gtk_menu_popup (GtkMenu *menu, GtkWidget *parent_menu_shell, GtkWidget *parent_menu_item, GtkMenuPositionFunc func, gpointer data, guint button, guint32 activate_time)

The main problem is how to pass a Go function go to C.

GtkMenuPositionFunc func

I can't find any similar code to do this besides the _go_glib_callback in glib.go

gtk.GTK_WINDOW_TOP_LEVEL
to be
gtk.WINDOW_TOP_LEVEL

go install github.com/mattn/go-gtk...

can't load package: github.com/mattn/go-gtk/example/builder: .../src/github.com/mattn/go-gtk/example/builder: found packages main (builder.go) and callback (callback.go)

go version 5843 - in gtk.go 789 812 and 834 -

seems the
authors.Data
documenters.Data
artist.Data

no longer have a .Data method

Regarding this func in gtk.go:
func (v *GtkTreeModel) GetIter(iter *GtkTreeIter, path *GtkTreePath) bool

There is something wrong with it, as the path parameter is not passed to C._gtk_tree_model_get_iter(), the newly created path_ is passed instead, and this error is generated:
Gtk-CRITICAL **: IA__gtk_tree_model_get_iter: assertionpath->depth > 0' failed`

This fixes the error:

func (v *GtkTreeModel) GetIter(iter *GtkTreeIter, path *GtkTreePath) bool {
    ret := gboolean2bool(C._gtk_tree_model_get_iter(v.TreeModel, &iter.TreeIter, unsafe.Pointer(path)))
    return ret
}

However, when using GetValue() with the resulting iter like that:
treeModel.GetValue(&iter, 1, &value)
I get this:
Gtk-CRITICAL **: gtk_tree_store_get_value: assertionVALID_ITER (iter, tree_store)' failed`

Steps:

1. pull tip (as of today).
2. Add this patch: http://codereview.appspot.com/4133041/

works!!

More detailed instructions:

If anyone wants to set up a build environment on windows, you need:
MinGW and MSYS. An easy way (but 32 bit only and a bit 'non-standard'), is to
use this installer: http://sourceforge.net/projects/lunac/files

If you don't use this installer the paths you need to use will be different than the ones I use!

Get and unzip into the top level directory, bison, diffutils, ed from the Gnuwin32 project.
You need the binaries, the dev packages and the dependancies!

Use Tortoisehg or command line hg to pull the latest go source to C:\MinGW\go
Set the environment variables needed for go:
GOARCH set to: 386
GOBIN set to: C:/MinGW/go/bin
GOOS set to: windows
GOROOT set to: C:/MinGW/go

Add the patch at: http://codereview.appspot.com/4133041/
(I'll add the steps required to do this if anyone really cares) ;)

Build go by launching MSYS using C:\MinGW\msys.bat and cd to /go/src and entering the command ./all.bash

Get gtk+ from here:
http://ftp.gnome.org/pub/gnome/binaries/win32/gtk+/2.22/gtk+-bundle_2.22.1-20101227_win32.zip

You also need both the bin and dev files from here:
http://ftp.acc.umu.se/pub/gnome/binaries/win32/gtksourceview/2.10/
and from here:
http://ftp.acc.umu.se/pub/gnome/binaries/win32/dependencies/
you need the bin and dev files for the libxml2 library.

Unpack all of these into C:\MinGW\gtk+, then follow the directions in the gtk+-bundle_2.22.1-20101227_win32.README.txt to make pkg-configure happy.

Copy the msys.bat file at C:\MinGW to msysgo.bat and add set GOBIN=/go/bin
set GOROOT=/go near the top.

Pull the latest version of go-gtk using TortoiseGit or command line git to: C:\MinGW\go-gtk. Then start MSYS again using the msysgo.bat file...and cd /go-gtk and follow the directions in the README.md file to create go-gtk and the example programs.

I had to copy the zlib1.dll file from C:\MinGW\gtk+\bin into the examples before they would run.

I hope this helps! If it is too complex, just wait and I'm sure someone will get a pre-packaged windows installer going sometime soon...

i tried a trivial function port to get multi thread gtk support working, without success.
In particular i exported from c glib.thread_init gdk.threads_init gdk.threads_enter gdk.threads_leave, but executing gdk.threads_enter(); gtk.mainQuit(); gdk.threads_leave(); from a different thread in which gtk.mainLoop() was not executed, simply block the app in gtk.mainQuit().
is there any plan to add this support?

Filled an issue
https://code.google.com/p/go/issues/detail?id=3035
but it will take a long time.

If the binaries are in ./bin they, at the moment, can't find the other files.
I don't know what is the best way to solve this.

OS: Ubuntu 9.10
