Re: Need to restore a window to last size/position on restart

How does one set background color for entire line in textview?
Hello,
I have a function that takes the output of a spawned process and
displays that in a text buffer (part of a notebook widget). When the
spawned process is finished, I'd like to put some colorized text at the
bottom of the text buffer/view that alerts the user that the process is
done.
What I want is the entire line to have a background color of blue. The
code that I have so far just displays the blue background under the
text.
How do I make the entire line blue?
switch (status) {
case G_IO_STATUS_NORMAL:
return TRUE;
default:
/* Use a tag to make the DONE notification noticeable */
tag = gtk_text_buffer_create_tag (
buffer, done_notification,

thread stack size
Hi all, I'm trying to figure out why gthumb uses so much memory, even when it is displaying an empty folder. I've figured out that it is launching 6-8 threads, which each consume 10 MB each of writeable/private memory. pmap -d shows: mapped: 141352Kwriteable/private: 76352Kshared: 516K If I patch the code to use 64k stack size for new threads, like this: - priv-thread = g_thread_create (load_image_thread, il, TRUE, NULL); + priv-thread = g_thread_create_full (load_image_thread, il, 65536, TRUE, FALSE, G_THREAD_PRIORITY_NORMAL, NULL); memory consumption drops dramatically (and the program still works): mapped: 91284Kwriteable/private: 25872Kshared: 516K (There are still 2-3 10MB stacks that I don't understand fully yet). The gnome api says Only use g_thread_create_full() if you really can't use g_thread_create() instead. Why not? Are there any real downsides here? - Mike ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

how to increase refresh rate in Wireshark IO Graph
Hi, I was looking for a real-time network traffic graph generator, and the best I've found was of course in Wireshark. Still, it has a refresh rate of 3 seconds on my computer, even if my processor is 95% idle. The reason seems to be a lazy refresh from Gtk, and I don't know how to give it some priority. Or should I explicitly trigger the refresh somehow? I was trying to do a quick fix, but I've never been dealing with Gtk before. Anyone have an idea how to make it faster? What I've done as a quick and ugly fix was adding a g_timeout_add_full () to the end of gtk_iostat_init() to schedule some periodic redraw events. The one linr of code I've added was something like the following (sorry, no diff, I do not have the source here with me): g_timeout_add_full (G_PRIORITY_DEFAULT, 100, io_stat_redraw, io, NULL); (of course some other code is needed to clean up when the window is closed) This one line reduced the refresh rate to 1 sec, already much better, but I wasn't able to go below, even if I set the priority higher or the event rate to some milliseconds. I'm sure someone knowing Gtk can achieve much better with the right one line of code. Anyone knows the solution?

If it's a single file, you can just do:

Put that in a comment on the first line and you can just copy/paste to build.

Delay in Displaying Dialog
I'm encountering a problem in an application I'm working on which I don't understand. It may be due to a misconception I have with GTK+ functionality. The application has a main window which comes up with program execution. Further processing is driven by events initiated by the user selecting drop-down menu items from this main window. In one menu item a dialog is displayed where the user selects certain criteria with which to proceed. Upon completion of establishing the criteria the dialog is destroyed and a new dialog is created. Within this new dialog are a couple of boxes and a couple of tables. Within one of the tables is a non-editable text widget with a vertical scrollbar. A gtk_widget_show_all() is issued for this new dialog once it's created, however the dialog is not displayed at this point. Additionally, the first dialog has not yet disappeared from the display. Immediately after creation of this new dialog, text begins to be sent on a somewhat streaming basis to the text widget. After a few seconds the first dialog disappears and the secondary dialog appears. However, the only widget within the secondary dialog which appears is the text widget. No other widgets appear. The appropriate text begins appearing and scrolling within the text widget. But missing are the first four or five lines of text which were (probably) sent to the text widget during the time it was not displayed. After the text being sent to the text widget ends and process flow falls back into gtk_main() then all the other widgets within the secondary dialog appear including the first few lines of text which had been missing. Can anyone give me an idea (or point me someplace) which will tell me what's going on?

Question about write a new scrollbar widget inherit from GtkVScrollbar
Hi,
I'm new to write gtk widget. I'm planning to write a picasa style scrollbar,
firstly, write vertical one.
The new scrollbar inherit from GtkVScrollbar and with a vscale data member:
struct _GtkVPScrollbar
{
GtkVScrollbar vscrollbar;
GtkWidget *vscale;
}
The new scrollbar override realize, map, size request and size allocate and
expose.
In realize, the new scrollbar calls parent class, GtkVScrollbar's realize.
Vscale uses new GdkWindowAttr to create new gdk window for GtkRange's
event_window. The widget window use new scrollbar widget's parent window:
vscale-window = gtk_widget_get_parent_window (widget);
GTK_RANGE (vscale)-event_window = gdk_window_new
(gtk_widget_get_parent_window (widget), attributes, attributes_mask);
In map, size request and size allocate and expose, parent class' functions
of the new scrollbar widget and vscale are called respectively.
Now, there is an event window covered on original scrollbar and receives
mouse click events, but it is only a gray rectangle. The slider of vscale is
not shown correctly. I guess in expose, I can't just call parent class'
function directly but should do something more. But I don't have any idea of
what to do more.
If possible, please give me some point to continue the widget programming.
I've read some tutorials but they only said about basic new widget from
scratch, draw line or box; another is composite widget inherit from a
container, but I prefer inherit from GtkScrollbar.
Sorry for my poor English. It' welcome to discuss this issue with me
directly.
Regards,
Eric Tsai

This line leads me to believe that you may not be relinquishing control to the Gtk mainloop. When the text comes into the second dialog box, are you locking up the program until it is all read? For instance, are you simply reading from a socket or file descriptor repeatedly until the text has all been received? If so, that's most likely your problem. Gtk doesn't run in a separate thread, so when it is instructed to do something, such as display a widget, it actually queues the work to be performed later, by the Gtk mainloop. When a function of yours is called, such as a callback for a button being pressed, it is the mainloop which actually does the calling, and it is done with the expectation that the function will do its work quickly, and then return, allowing the mainloop to continue running, and dispatching input events, redrawing widgets, etc. If one of your callbacks takes an extended amount of time to do something, the mainloop is unable to run, thus making the UI unresponsive, preventing expose requests from being serviced, and other Bad Things. There are a few different ways around this problem. They all amount to deferring the work until later, and chopping it up into small pieces, so that it never actually blocks the mainloop for a significant amount of time. For example, you can set up an idle handler, which will be called by the Gtk mainloop whenever it doesn't have any other work to do. Inside of this callback, you could check the data source to see if any new data has appeared, and if so, add it to the text widget, and then quickly return (at which point the mainloop would continue running, and actually expose the new text on the screen.) I believe it's also possible to tell the mainloop about a file descriptor which should be watched, and have it call a function whenever new data appears. I have never used this tactic (hopefully someone else can clarify this), but you might try looking at the documentation for the Glib mainloop and the Gtk mainloop, both available at http://www.gtk.org/api/ . Good luck--if this turns out not to be the problem you're having, be sure to send a reply with some more description, and we'll see what we can do. --Matt ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

This typically happens when you don't return control the main loop.
Does your program respond at all while it's supposed to be pulsing?

my $timer = Glib::Timeout-add (10,\show_progress);
# timer will run until callback returns false
Gtk2-main;
sub show_progress{
$pbar-pulse();
return 1;
}
This test script does work as expected on another Linux machine (running
Debian Sarge with KDE), but the progressbar looks different (more like gnome,
whereas on Kubuntu (where it doesn't work), they have some KDE integration of
gtk and therefor a KDE progressbar).
You might also try setting the pulse step. The default is 0.1, but
you may need a different value for some reason or another. Difficult
to tell without more information.
Maybe the code above helps sorting out programming issues (as the test script
isn't mine:-)). Besides this, I don't know in which direction to search for
the cause or provide information? Maybe someone on the list can run the test
script on their Kubuntu to find out whether it's related to that?
Thanks a lot,
