Re: glade_xml_signal_autoconnect and user_data
To pass user data, you could either connect each signal using glade_xml_signal_connect() or you can write your own connect function using glade_xml_signal_autoconnect_full(). If you use GtkBuilder instead of LibGlade, you can pass the same user_data to each handler using gtk_builder_connect_signals(). - Micah Carrick Developer - http://www.micahcarrick.com GTK+ Forums - http://www.gtkforums.com dhk wrote: Is glade_xml_signal_autoconnect()only used for callbacks that don't take user_data?

Re: How do I catch right-click on a TreeView header?
You may be able to use gtk_tree_view_column_get_widget() since *I think* it's a GtkLabel (if not, you can make it so using set_widget()) and then connect to the button-press-event of that widget. - Micah Carrick Developer - http://www.micahcarrick.com GTK+ Forums - http://www.gtkforums.com John M Collins wrote: > Is there any way I can detect a right-click on a TreeView header? > > I have a sorted tree view and left click is sorting the rows according > to the header just fine.

Re: Scrolling text in Gtk
In the book "Foundations of GTK+ Development", there is a chapter on
creating custom widgets in which a marquee widget is created (which
scrolls text across the widget).

Using GtkTreeViewDropPosition in drag and drop
I haven't worked with drag and drop all that much. I have an application in which I'm dragging rows from one tree view onto another tree view. It's working great except for one piece... Using the gtk_tree_view_get_dest_row_at_pos () in the "drag-motion" signal handler, I am able to get the GtkTreeViewDropPosition and change the drop indicator accordingly based on the return value (root nodes accept drop into, child nodes only show dropping before or after). However, using that same call to gtk_tree_view_get_dest_row_at_pos () in the "drag-data-recieved" signal handler gets the path okay, but does not set the GtkTreeViewDropPosition. Thus, the row is not always dropped into the position that was indicated by the motion event. Can anybody tell me why the GtkTreeViewDropPosition wouldn't be obtainable in the "drag-data-recieved" handler? -- - Micah Carrick Developer - http://www.micahcarrick.com GTK+ Forums - http://www.gtkforums.com ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Re: Drag and Drop Selection Content
Here's how I understand it... In the "drag-data-get" callback I call 'g_array_free(tracks, FALSE) ' to free the struct but not it's data since gtk_selection_data_set() is going to copy it. In the "drag-data-recieved" callback I call g_free() on the data, but do NOT call g_array_free as that is already going to be freed after the drag-drop is completed.

I'm currently doing so with this: gtk_selection_data_set (data, data->target, 8, (gpointer) tracks, sizeof (GArray)); Where 'tracks' is a GArray of uint32_t integers.

Mixing of memory allocation methods with application
I have a GTK application which is working with a C library (Libmtp). This C library uses standard C functions such as free, malloc, strndup, etc. When I am working with a structure from this library, I should be using those same functions on those structures right? Because *my* parts of my application (elsewhere) are using the g_ functions. For example, right now I have a structure coming from Libmtp for playlists. When renaming that playlist I used: free (playlist->name); playlist->name = g_strdup (new_name); Is this going to cause problems? Should I make sure to use: free (playlist->name); playlist->name = strdup (new_name); Also, these structures have arrays of tracks (uint32_t*). I have some routines which replace that array with the 'data' member of a GArray... that's probably *bad* since GArray doesn't use regular malloc()... right? -- - Micah Carrick Developer - http://www.micahcarrick.com GTK+ Forums - http://www.gtkforums.com ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: Scrolling to end of scrolled window when first displayed
There is an example of scrolling a GtkTextView to the end at http://www.gtkforums.com/about1307.html If it's not working "initially" but works in callbacks, perhaps that is because the widget isn't shown yet. After the text view and scrolled window have been shown, do while (gtk_events_pending()) gtk_main_iteration (); before trying to scroll to the end. Or perhaps try connecting to the text view's "show" or "realized" signals. Not sure if that would work but it's an idea anyway. - Micah Carrick Developer - http://www.micahcarrick.com GTK+ Forums - http://www.gtkforums.com John M Collins wrote: > I have a GtkTextView displaying some text - actually a log file in a > Scrolled Window. > > I should like it to start off with the scroll at the bottom of the file > - i.e. showing the most recent entry in the log file. > > How do I do this? > > I have tried: > > GtkAdjustment *adj = > gtk_scrolled_window_get_vadjustment(GTK_SCROLLED_WINDOW(scroll)); > gdouble val = adj->upper - adj->page_size; > if (val < adj->lower) > val = adj->lower; > gtk_adjustment_set_value(adj, val); > > and also > > gtk_text_buffer_get_end_iter(textbuf, &iter); > gtk_text_view_scroll_to_iter(GTK_TEXT_VIEW(view), &iter, 0.0, FALSE, > 0.0, 1.0); > > But neither work initially - however they do work in callbacks once the > window is up and running. > > Is there some "first time display" signal I need to put one of those in? > > Thanks for any help. > > John Collins Xi Software Ltd www.xisl.com > > ___ > gtk-app-devel-list mailing list > gtk-app-devel-list@gnome.org > http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list > > ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Feedback on my Win32 GTK+ Experience
Hey everyone. I built a little GTK+/ Libglade project on Win32 over this holiday primarily just so I knew how to do it. However, I also have a project in the queue which will require this knowledge. I'm going over my installation notes getting ready to put them up on my blog, however, I was hoping to get some feedback on some of the issues I had first. I opted for MinGW and MSYS as I would like to be able to deploy Windows versions without the need for cygwin and I understand MinGW is the correct choice for this. I primarily used the links from Tor Lillqvist’s GTK+ for Windows page to copy the necessary libraries (and dev headers). I had problems with 2 of the packages. 1. libxml-2.0 from libxml2-2.6.30.win32.zip was missing the .pc file for pkg-config. I simply found this file in the sources elsewhere and copied to C:\MinGW\lib\pkgconfig\libxml-2.0.pc. Is this normal? 2. zlib from zlib123-dll.zip had a couple of things. First, I had to copy zlib1.dll to my bin/ directory. Secondly, the pkg-config files used -lz as the linker flag, and thus I had to copy /lib/zdll.lib to /lib/libz.a. The USAGE file said to rename zdll.lib to libzdll.a which I ALSO did to ensure it works either way. Is this right? Why isn't it libz.a already? Once I had it working, I wanted to figure out how I might deploy the application. As I understand it, I can simply write my installer the same way I did back in my Windows programming days and deploy it with the DLL files necessary as round in the /bin dir. I found that I can copy these to C:\WINDOWS\SYSTEM32\ on a target system which does not have cygwin or MinGW or anything else and my GTK+/Libglade application runs fine. I'm assuming this is what I would do to deploy a GTK+ windows application (using some kind of installer such as Nullsoft or Inno Setup making sure not to overwrite newer files). 3. Is copying the .DLL dependencies to the system (\WINDOWS\SYSTEM32) directory appropriate for the deployment of GTK+ applications on Win32? I know it "works", but is that the standard convention? Thanks to anyone with the time to respond. I appreciate the help I've gotten thus far. Being limited on time I don't have much more time to research and I don't want to mislead readers of my blog. Not to mention, I would be more adept at helping people with their win32 quesions on http://www.gtkforums.com -- - Micah Carrick Developer - http://www.micahcarrick.com GTK+ Forums - http://www.gtkforums.com ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

A quick "cheap trick" you could do is:

gtk_window_show_now (GTK_WINDOW(window2));

Re: question about tabs on notebook
Do you mean which tab is selected by default when the program starts? If so, before showing the notebook, assuming that the first tab is selected by default, call gtk_notebook_next_page(). You could also use gtk_notebook_set_current_page() to explicitly select the 2nd page by passing 1 as the index. If you mean that you want the 2nd page to be where the 1st page currently is, why not just change the glade file? - Micah Carrick Developer http://www.micahcarrick.com | http://www.gtkforums.com shawn bright wrote: > Hello there all, > > i am using GTK and glade to create a front end to our data engine. > The thing is, it uses a notebook with 4 tabs.

Part of Desktop GUI development is allowing your program to fit the customer's needs (ie 10 years ago I preferred tiny little fonts, and now that I'm going blind they get progressively larger). Font sizes are specified in 'System' -> 'Preferences' -> 'Fonts' under GNOME in FC6. If you really want to specify your own font, you may want to use an rc file: http://developer.gnome.org/doc/API/2.2/gtk/gtk-Resource-Files.html -- - Micah Carrick Freelance Developer http://www.micahcarrick.com | http://www.gtkforums.com ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Re: GtkEntry text selection
You can use the "focus" signal to set the cursor position using gtk_editable_set_position with a position of -1 to indicate the end of the text. - Micah Carrick http://www.micahcarrick.com | http://www.gtkforums.com Anurag Chaudhary wrote: > When I bring focus to a GtkEntry, all of its text gets selected by > default.

Re: Trimming GtkEntry Text
(custom_command == NULL || sizeof(custom_command) <= 0)
custom_command is a gchar pointer, so, using sizeof simply gives you the
size of the pointer, not the length of the string.
"sizeof(custom_command) <= 0" will always be the size of a gchar pointer
(4 bytes on my system).
If you're looking for the length of characters in the string, try using
g_utf8_strlen() instead.
