Closing an application
Sir,
I am trying to ascertain the "exit" method from an
application.In the following application, I have
defined an event for the button and connected it with
signal gtk_main_quit. I have not defined this
function, separately. I am relying on the
system_provided function for this.
I have two questions.
1) Is it a proper method of exiting an application?
2) Which function call should I use in the button
event, out of the two choices avilable, namely
"gtk_exit" and "gtk_main_quit"?
Here is the code, that I am using.
#include
int main(int argc, char *argv[])
{
GtkWidget *window;
GtkWidget *button;
gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
button = gtk_button_new_with_label("Quit");
gtk_signal_connect(GTK_OBJECT(button), "clicked",
GTK_SIGNAL_FUNC (gtk_main_quit),
NULL);
gtk_container_add (GTK_CONTAINER(window), button);
gtk_widget_show(button);
gtk_widget_show(window);
gtk_main();
return 0;
}
bye
shiraz

GtkRange and adjust_bounds
Hi, I'm looking for a way to automatically grow a pixmap in a GtkScrolledWindow if the user tries to scroll farther to the right or bottom when the scroll thumb is already at the edge. I've tried a bunch of things and there doesn't seem to be a documented way of finding out if someone attempts to scroll when the thumb is at the edge. GtkScrolledWindow's GtkAdjustment emits value_changed if the value has changed, but in this case it won't have changed. I dug through the GTK 2.2 source and the adjust_bounds signal in GtkRange seems to do exactly what I want: it's emitted whenever someone clicks the scroll buttons or drags the thumb. My question is, since the signal isn't documented anywhere, can I rely on it still being there in a later release? :) Thanks, Mike ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
GtkTextBuffer + integers?
Hey everyone, I am trying to output an integer to a gtktextbuffer, the widget only seems to take a gchar as data and when i try to cast the integer to a char it compiles but then segfaults when gtk_buffer_set_text() calls strlen(). Does anyone have any idea how I can get an integer value to the buffer? thanks!

Quoting: http://developer.gnome.org/doc/API/2.2/gdk/gdk-Event-Structures.html#GdkEventKey gchar *string a string containing the an approximation of the text that would result from this keypress. The only correct way to handle text input of text is using input methods (see GtkIMContext), so this field is deprecated and should never be used. (gdk_unicode_to_keyval() provides a non-deprecated way of getting an approximate translation for a key.) The string is encoded in the encoding of the current locale (Note: this for backwards compatibility: strings in GTK+ and GDK are typically in UTF-8.) and NUL-terminated. In some cases, the translation of the key code will be a single NUL byte, in which case looking at length is necessary to distinguish it from the an empty translation.

Signals - newbie
Hello, I'm afraid that I'm a bit confused regarding gtk_object_class_user_signal_new. Has it been deprecated? I noticed that it is documented in 1.2's API (with no mention of future deprecation), but that there is little mention of it in the 2.0 API reference short of a brief paragraph in the signals section. Also, running cat * | grep gtk_object_class_user_signal_new in the gtk directory is returning nothing. I would really rather avoid rewriting all of the widgets to support the signals that I need them to, not only because of time issues, but also because it seems like a very very bad idea. Is there some other way to that I'm (quite likely) missing? Thanks for any help Brooke ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
Bug in GtkCurve?
The following code, results in a straight line:
gfloat points[] = {0, 0, 25, 25, 50, 50, 75, 50, 85, 55, 100, 100};
gtk_curve_set_range (GTK_CURVE(curve) 0, 100, 0, 100);
gtk_curve_set_vector (GTK_CURVE(curve), 6, points);
gtk_curve_set_curve_type(GTK_CURVE(curve), GTK_CURVE_TYPE_SPLINE;
Which one would not expect (unless I am missing something). I cannot
seem to initialize a curve to anything different to a straight line.
Points in the middle seem to be ignored.
I am running GTK 1.2.10 on a RH 7.3. A person running 1.2.8
reported it works there.
Here is the code that reproduces the problem on my platform:
#include
gint delete_event( GtkWidget *widget,
GdkEvent *event,
gpointer data )
{
gtk_main_quit();
}
int main( int argc,
char *argv[] )
{
GtkWidget *window;
GtkWidget *curve;
gfloat points[] = {0, 0, 25, 25, 50, 50, 75, 50, 85, 55, 100, 100};
gtk_init(&argc, &argv);
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
curve = gtk_curve_new ();
gtk_signal_connect (GTK_OBJECT (window), "delete_event",
GTK_SIGNAL_FUNC (delete_event), NULL);
gtk_container_set_border_width (GTK_CONTAINER (window), 10);
gtk_container_add (GTK_CONTAINER (window), curve);
gtk_widget_show (curve);
gtk_widget_show (window);
gtk_curve_set_range (GTK_CURVE(curve), 0, 100, 0, 100);
gtk_curve_set_vector (GTK_CURVE(curve), 6, points);

colors change.
Hello, I'm using gtk to make a design of lines, rectangles and other polygons. My question is why when I draw the objects, for example, lines and after that I draw the rectangles, the first line I was drawed changes its color to the rectangle's color? And so on with the other objects. See here some code to how I draw any, for example the rectangle: ... gdk_colormap_alloc_color(a->gdkcolormap, &vr[i].rcolor, TRUE, TRUE); gdk_gc_set_foreground(a->gdkgc, &vr[i].rcolor); gdk_gc_set_line_attributes(a->gdkgc, vr[i].rgrosor, GDK_LINE_SOLID, GDK_CAP_BUTT, GDK_JOIN_MITER); gdk_draw_rectangle(a->drawingarea->window, a->gdkgc, TRUE, vr[i].rx, vr[i].ry, vr[i].ranchura, vr[i].raltura); ... thanks in advance, ana. ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
