gtk box and flow layout
Hello! Can I create flow layout box in gtk like java FlowLayout Layout Manager? Or it is need to create derivative class (from GtkTable for example) and release it behaviour itself? Thanks.

A few drawing questions
Hi, I'm working on a game and I was wondering what would be best to use for drawing? I'm having a hard time figuring out how all the different drawing APIs fit together. As far as I can tell there is GDK, Cairo, GnomeCanvas (dead?), and other things like GooCanvas. Everything get's drawn to a gdk window in a drawing area, right? I want to draw a map (a bunch of tiles) to the screen. Also I'll need to draw things on top of this, like nicely rounded, semi-transparent area with information when a user requests more information on a certain entity in the map. Eventually, I'd like to do small visual effects, like animating water (nothing fancy) and moving the player character around without jumping from tile to tile. I've played around with gdk a little bit. I ended up drawing the entire map to a gdk window (256x256 tiles and tiles are 32x32 pixels) and put it inside a ScrolledWindow. But as you can imagine that ate up a lot of memory. I guess the right approach would be to only have the drawing area as big as will fit in the window and then update it when the area is scrolled? I'm programming in C#, but I decided to post here instead of gtk#, because I think there's more people here. Thanks for the help. -- Mark A.

Re: gtk box and flow layout
daa84,
You may want to explore using the GtkLayout container. From what I know
of the Java FlowLayout, both GtkTable and GtkLayout are close
approximations of the FlowLayout.

In case you want row-breaking functionality of FlowLayout (e.g. when third widget is placed below the first two since there is not enough width), you likely need a custom container, as standard ones don't support this. Otherwise you probably just want GtkHBox/GtkVBox. Paul ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Problems with Threading Concept
Hi all,
I have GUI developed based on gtk+-2.2.0,
1) I have button to start some process (continuous).
2) I need to stop that process, when i click the same button.
to do the above tasks i developed a small application using threading
concepts...
//
#include gtk/gtk.h
#include stdio.h
#include pthread.h
int flag=1,toggle=0;
int i=0;
pthread_t yes_tid;
void hello()
{
while (flag)
{
gdk_threads_enter ();
printf (%d %d\n,i++,flag);
if (gtk_events_pending())
gtk_main_iteration(); // Handle unprocessed GTK events
gdk_threads_leave ();
}
}
void hello_print( GtkWidget *widget,
gpointer data )
{
if(toggle==0)
{
toggle=1;
flag=1;
pthread_create (yes_tid, NULL,(void *)hello, NULL);
}
else
{
flag=0;
toggle=0;
}
}
int main(int argc,
char *argv[] )
{
GtkWidget *window;
GtkWidget *button;
g_thread_init (NULL);
gdk_threads_init ();
gdk_threads_enter ();
gtk_init (argc, argv);
/* create a new window */
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
g_signal_connect (G_OBJECT (window), destroy,
G_CALLBACK (gtk_main_quit), NULL);
gtk_container_set_border_width (GTK_CONTAINER (window), 100);
button = gtk_button_new_with_label(click it);
g_signal_connect (G_OBJECT (button), clicked,
G_CALLBACK (hello_print), NULL);
gtk_container_add (GTK_CONTAINER (window), button);
gtk_widget_show (button);
gtk_widget_show (window);
gtk_main ();
gdk_threads_leave ();
return 0;
}
//
But the problem here for me is, the stop is not happening immediatly
after the click..
Is there any mistake the way i am doning it ... or do i need to follow
any other procedure for it.. please help me out...
Regards,
Naveen.
