[gtk+osx] window is visible but does not accept focus

[KieSoft]

Hi!

I'm trying to port my Linux app on MAC OS X. I can compile the code and
window is visible but does not accept focus, nor is it movable. I thought
that's my problem and wrote a small GTK app. I get the same result with that
test app too: window does not accept focus. Can you help me to solve the
problem?

Here are my code:

----------------------------------------------------------------------------
--------------
gtktest.mak:

CXXFLAGS=-g -Wno-long-double -Werror -D_FILE_OFFSET_BITS=64 -I/gtk-osx-0.6 -
I/gtk-osx-0.6/glib-1.2.10 -I/gtk-osx-0.6/gdk
OBJS=gtktest.o

gtktest : $(OBJS) ; \
    gcc -o gtktest $(OBJS) -lpthread -ldl -lstdc++
`/gtk-osx-0.6/gtk-config/gtk-config --libs`;

----------------------------------------------------------------------------
--------------
gtktest.cpp:

#include <stdlib.h>
#include <stdio.h>
#include <sys/stat.h>
#include <sys/types.h>
#include <math.h>
#include <time.h>
#include <locale.h>
#include <assert.h>
#include <ctype.h>
#include <gtk/gtk.h>

static gint close_app_event(GtkWidget *widget, GdkEvent *event, gpointer
data)
{
gtk_main_quit();
return FALSE;
}


int main(int argc, char* argv[])
{
gchar buffer[64];
srand (time (NULL));

gtk_set_locale ();
gtk_init (&argc, &argv);
gdk_rgb_init();

GtkBindingSet *binding_set = gtk_binding_set_by_class (gtk_type_class
(GTK_TYPE_WIDGET));
gtk_binding_entry_add_signal(binding_set, '9', GDK_CONTROL_MASK |
GDK_RELEASE_MASK, "debug_msg", 1, GTK_TYPE_STRING, "GtkWidgetClass
<ctrl><release>9 test");

GtkWidget *window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
gtk_window_set_policy (GTK_WINDOW (window), FALSE, FALSE, FALSE);
gtk_widget_set_name (window, "main window");
gtk_widget_set_usize (window, 200, 400);
gtk_widget_set_uposition (window, 20, 20);
gtk_signal_connect (GTK_OBJECT (window), "destroy",
GTK_SIGNAL_FUNC(gtk_main_quit),  NULL);
gtk_signal_connect (GTK_OBJECT (window), "delete-event", GTK_SIGNAL_FUNC
(gtk_false), NULL);

GtkWidget *box1 = gtk_vbox_new (FALSE, 0);
gtk_container_add (GTK_CONTAINER (window), box1);

if (gtk_micro_version > 0)  sprintf (buffer, "Gtk+ v%d.%d.%d",
gtk_major_version, gtk_minor_version, gtk_micro_version);
else sprintf (buffer, "Gtk+ v%d.%d", gtk_major_version, gtk_minor_version);

GtkWidget *label = gtk_label_new (buffer);
gtk_box_pack_start (GTK_BOX (box1), label, FALSE, FALSE, 0);

GtkWidget *button = gtk_button_new_with_label ("close");
gtk_signal_connect(GTK_OBJECT (button), "clicked", GTK_SIGNAL_FUNC
(close_app_event), window);
gtk_box_pack_start(GTK_BOX (box1), button, TRUE, TRUE, 0);
GTK_WIDGET_SET_FLAGS (button, GTK_CAN_DEFAULT);
gtk_widget_grab_default (button);

gtk_widget_show_all (window);
gtk_main ();
return 0;
}

I took the code from gtk-osx-0.6 demo app.

Looking forward to hearing from you soon,

Best regards,
Igor

Its an old issue.For some reason Apple have made it awkward to make
command line programs
have a GUI. There's a number of way's around this, the easiest is to
wrap the executable in a bundle.

There is also a way to add a resource, I'm not to clear about it but the
FLTK GUI tool set has
a program that can do it, although IIRC it's just a script and a
resource file.

If you can use a script of some sort to launch your program, I'd
recommend Platypus ( http://sveinbjorn.sytes.net/platypus ). I've used
it for several programs and it works great. The program that uses it
that you've most likely used is Gimp.app (the GiMP packaged for OSX).
