Re: multi thread app and often variable accessing

Hi, As far as I understand, g_atomic_int_get/set will do the job just fine, as long as you're sure the only part that needs to be atomic is the getting and setting. However, if the hardware you are running on does not provide an atomic way of getting/setting an int, (eg: int is an int32 and the ha

Re: drawing to textview's gdk_window

Hi, Using g_signal_connect(), make your callback return false, so that the original callback (that obviously renders the text) will then be called also. Jonathan On 6/8/07, Luka Napotnik <[EMAIL PROTECTED]> wrote: > > I now connected the expose-event signal to a callback function that > draws a

Deriving from GtkWindow and libglade

I want to derive a new class from GtkWindow to represent a top-level window which contains objects from a Glade XML file. Since the glade_xml_get_widget functions returns a new object, I'm not sure what to do in the object's "init_instance" function to copy the properties (and children) of the retu

Building portable apps with portaccess unter qtk/glib

I want to build a widget to communicate over com, lpt and usb under the cygwin32/windowsport oft glib/gtk with a gtk-widget that set parameters for the interface, but plattform-independend and handle communikation. Does a method for the gtk/lib-windowsport exist to do this? Under linux /dev/ttyS0

Re: drawing to textview's gdk_window

I now connected the expose-event signal to a callback function that draws a rectangle to the widget. The problem is that the font is under the rect. if I call g_signal_connect_after() and no text appears if I call g_signal_connect() but the rect is visible. I get the GdkWindow of the textview using

Re: drawing to textview's gdk_window

Luka, Sounds like an expose event needs to be signaled. I use GDK only and not GTK so I am not sure how much of GTK is doing event processing. Chris > Hello. I'm trying to draw a rectangle of a textview's background > GdkWindow. First I get the gdk_window of the textview and and then try > ot

drawing to textview's gdk_window

Hello. I'm trying to draw a rectangle of a textview's background GdkWindow. First I get the gdk_window of the textview and and then try ot draw on it. But it doesn't work. Why? - #include int main(int argc, char **argv) { GtkWidget *window; GtkWidget *text;

Okay, I've figured out why g_slice_set_config wasn't working...at some point g_quark_from_static_string was being called before g_slice_set_config, hence the error. On 6/8/07, Raja Mukherji <[EMAIL PROTECTED]> wrote: > Do I set the environment variable? Because code like > > setenv("G_SLICE", "alw
