Buttons in groups
Hi, Is there a way of placing a GtkToggleButton into a group so that when one button is selected the others in the group automatically get unselected? Best regards, Chris.

RE: Buttons in groups
Hi, Thanks for the quick reply. I should have said that its for groups of tools, and I'd like to have icons on the buttons - I'm not sure that GtkRadioButtons can use icons, but if they can they'd be perfect for me. I see that Fig. 3.9 in the HIG suggests visually how to implement a toolbox with multiple groups of buttons, which is the sort of thing I had in mind. Best regards, Chris.

GtkRadioButton is a GtkContainer (as any button) and can contain anything, just don't use the convenience cosntructors and pack the icon or whatever yourself. And see also gtk_toggle_button_set_mode(). You should also consider GtkToolbar if you want to create a toolbar...

Collapse and expand in GtkTreeView
Hello! When I expand an item in a GtkTreeView that I just collapsed before, only the first child level of the expanded item is shown. Example: Before collapsing: - Item 1 - Item 11 - Item 111 - Item 112 - Item 12 After collapsing Item 1 and re-expanding it: - Item 1 - Item 11 - Item 12 Is there a possiblity (a property or whatever) to get the same state as before collapsing, or do I have to handle it myself?

I wrote that, not James Scott. Often times you need to hear it first, before you have a chance of believing it. I hadn't heard that yet.

Setting G_SLICE=always_malloc at runtime
Hi All, I'm writing a binding for Gtk to my programming language Wrapl, and want to make sure that all memory is allocated by the Hans-Boehm garbage collector. The glib/gobject shared libraries are loaded dynamically and I call g_mem_set_vtable to change to GC_malloc, GC_realloc, GC_free, etc. However g_slice doesn't use these. I know that setting the environment variable G_SLICE to always_malloc will solve this, but I want to do this at runtime, just after the relevant shared libraries are loaded, but before they are used (basically at the same time as when I'd call g_mem_set_vtable). Is this possible? Thanks, Raja ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

multi thread app and often variable accessing
Hi! I'm working on small multi thread application based on Gobject. In one of my objects I have integer variable, which determine current object's status. The problem is, that I need to read it's status really often, so it will be to expensive to lock and unlock mutex all the time. Can I use there atomic operations provided by GLib instead of mutex locking and unlocking system? I mean, if g_atomic_get and g_atomic_set would not occur any problems, when I will try to access the same variable from two thread at the same time? -- Cya!

Re: Setting G_SLICE=always_malloc at runtime
Do I set the environment variable? Because code like setenv(G_SLICE, always_malloc, 1); g_thread_init(0); doesn;t seem to work. I noticed the g_slice_set_config functions in gslice.h and tried g_slice_set_config(G_SLICE_CONFIG_ALWAYS_MALLOC, 1); but this gives me the error (process:6533): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed and also does not work. What am I doing wrong?
