Re: How to make a GtkButton respond to a key press

I'm totally lost in the documentation bouncing between actions, accelerators, accerator groups, action groups, ui managers, etc, and I can't find a SIMPLE example. Any help would be greatly appreciated. There are menu accelerators and there are mnemonic accelerators. What you need to use for a quit button is a mnemonic accelerator. You do not attach to any key-press signal. Attach to the button clicked signal. GTK provides the functionality to capture the keyboard press and route it to the button click.

Hence, it seems that I also need to use function like, e.g., pango_font_description_set_weight, etc., but I'm not fully sure about this. You are close. You need to use gtk_widget_modify_font(). You pass in a font description created by: PangoFontDescription *fontDesc = pango_font_description_from_string( monospace 10 ); This would set the entry text to a monospace-type font with 10 point size.

window icon resolution
When I call gdk_pixbuf_new_from_file() to set a window icon, the resulting image in the Gnome Shell ALT+TAB switcher is fuzzy and clearly low-resolution. The window icon is a 128x128 pixel 24-bit PNG file. When I have the file displayed in another viewer (eog) and ALT+TAB, the Gnome Shell image is smaller than the full image in eog, but clearly fuzzier and lower resolution. Other applications such as Pidgin, Firefox, or Geany display clear, high-resolution icons. What am I doing wrong that other applications are doing right? I checked the Geany source and saw it had inlined the GdkPixbuf image and loaded it that way. Why would that make a difference?

You will have two choices: 1. Copy an entire GTK widget and give it a unique name. Example: GtkButton becomes GtkMyButton 2. Create a shell widget that uses existing GTK widgets inside of it to do what you want. In the event you need to touch the GTK widgets inside, you can make your new widget a simple struct and have pointers to the interior GTK widgets.

jjacky wrote: Anyways, I don't have a problem with creating a new (shell/composite) widget using another one inside of it, it's actually exactly what I did in my example: created a widget JjkCalendar which contains a GtkCalendar. Your composite widget project is similar to mine. I created a custom widget that is a text input combo box that if you click on the drop down button it displays a GtkCalendar. You can type in the date (in any format) and it will select the date in the GtkCalendar widget. It's just that I felt (from tutorials and such I read) that such (composite) widgets were only using widgets they contain and combining them together, rather than modifying their behaviors. You can certainly modify their behaviors. I catch and call signals that you normally wouldn't in order to parse and display the correct date format and positioning of the GtkCalendar widget. I guess my question is more: how do I affect this widget's internal behavior? how do I add a new feature (which might imply alter current way to draw the widget) ? That is, do something not really supported/planned by the widget's public API. If signal catching/calling are not enough then you might be best off creating a brand new widget. It seems you want to change the drawing of the GtkCalendar widget so you are on the right track of creating your own widget. Like I said, in the example code I posted, in order to do that, and alter GtkCalendar's behavior, I needed to redefine GtkCalendarPrivate in my widget, so that I could change values contained the GtkCalendar's private struct. Also had to copy/paste a few functions as well -- is that okay, or will it lead to problems? And if so, what's the right way to do it then? I'll admit I hadn't looked at your example the first go around. If you wish to customize the positioning, coloring, and text of each day then you must create your own widget. However, if all you want is to color the current day, then I think there already exist ways to do this without having to create a whole new widget. First, you have to set the day, and second you can theme it as you are trying to do already. Setting the day alone will color the current day. Is that all you want?

Where as with ssh the OS just provides you with UIDs. I'm not a fan of the completely separate user database just for the one program architecture either. -(related to authentication) key management - ssh does all that already (ssh-agent, etc) (although the gnome-keyring library works for *nix) -more options for an admin to deal with -as legacy as ssh is, it does so much so well. It just feels like leveraging that would be a good idea. Also I might be thinking of the wrong project, but I have some vague memory of GnuTLS taking the downloads on their site down in protest after 911 (unless you donated money) or something quacky like that. (I'm pretty sure I shouldn't have said that, but whatever). You could have a TLS session without x509 auth and just use PAM or LDAP for user auth. Something like that is not provided by a single function call though. Too many options? If you make the server/client yourself then it's limited to however you program it. I don't understand your reasoning for this complaint. SSH is great for remote terminal sessions, but not much more. It sounds like you just want to be extremely lazy. Suck it up and write your own implementation using the standard library tools available. It will be portable -- my GnuTLS apps run on Linux and Windows. I don't remember anything about GnuTLS and any political agenda as that was before my time in FOSS, but I wouldn't be surprised. ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

And here I was thinking that the entire point of writing computer programs was so we could be lazy. Note my word *extreme*. I'm all for easy programming -- but it sounded like the OP wanted to write three function calls and be done. Anyway, Thomas: as long as you're able to parse the responses you get from the server, using g_spawn_async_with_pipes() and probably GIOChannel, you should be able to do what you want. It probably would be more reliable to write your own TLS server and client, but might not be faster or easier. I'm not sure about the win32 issues, though. There should be zero win32 issues. One of my Win32 apps uses a GTK gui to talk to a Linux server daemon using XML-ized data packets.

It's already sad enough that there is no way to merge this world with https client authentication, somehow. SVN is one example of something that let's you keep things simple administratively by optionally using the ssh security model. I hate to say it, but the windows named pipes over SMB is another good model (the implementation however...). Passwords all over the place = evil. Each application asking you to decrypt a private key / cert on its own = annoying. Again gnome-keyring-daemon is on the right track, but I need something for the windows side. I understand your authentication requirement, but I haven't written a program myself that masters these interfaces (PAM, LDAP, etc) so this will be my last comment on this. I have extensive knowledge using these interfaces across multiple applications however. There was something that crossed my mind when I first read your OP and this may or may not be what you are looking for... http://www.libssh2.org/wiki/index.php/Main_Page There's packages in Fedora (and probably Debian, etc) for this library, but I have not used it.

From: Guenther Meyer [EMAIL PROTECTED] To: gtk-app-devel-list@gnome.org Date: 12/11/2008 02:22 AM hi, I have GtkLabels packed inside some vboxes or tables, the width of the box is determined by the size of some other elements (buttons, listviews, ...). when the text inside the labels is changed, and this text is too long to fit, the box automatically resizes, which distorts the whole window layout and pushes some widgets off the screen. so how can I fix the width of the GtkLabel (which I don't know at creation), and let the text automatically wrap or scroll, if it doesn't fit? gtk_label_set_line_wrap( GTK_LABEL( label ), TRUE ); However, for this to work you must set a maximum size on the label. gtk_widget_set_size_request( GTK_WIDGET( label ), 100, -1 ); 100 being 100 pixels wide.
