GtkHScale: Jump-to-position by left-click instead of middle-click?
Hello everybody, I am new to GTK. I am trying to develop a small music player using GTK GStreamer. I use GtkHScale for the progress bar, which is responsible for updating the track progress allow user to move to different time position in the track. Everything works fine until now, except that I can not use left-click button to snap (or jump) to random position in the GtkHScale. Instead, I have to either drag or right-mouse-click. I have tried to solve this problem for several days and still can not figure out how to use left-click to jump to different position in the GtkHScale. I have searched through the GTK+ mail archive reference but found no place talking about this. Does anybody here know how to implement this functionality for GtkHScale? If so I hope you can give me a hint. Thank you and have a good day! -- Phong V.

The following is a kluge, but I suppose if you want the first button to invoke the same response as the middle button it should be all right (written in Python for brevity): from gi.repository import Gtk def button1to2(scale, event): if event.button == 1: event.button = 2 return False adj = Gtk.Adjustment.new(0.0, 0.0, 1.0, 0.001, 0.01, 0) scale = Gtk.Scale.new(Gtk.Orientation.HORIZONTAL, adj) scale.set_round_digits(3) scale.connect(button-press-event, button1to2) scale.connect(button-release-event, button1to2) window = Gtk.Window() window.add(scale) window.set_default_size(400, -1) window.show_all() window.connect(destroy, Gtk.main_quit) Gtk.main() Yeti -- Phong V.

Insert different children into the same parent in GtkTreeStore?
Hello everybody, I am trying to write a music manager software that import the files according to artist and album. Each artist can have many album and each album can have many songs. Therefore, I decided to use GtkTreeStore to nest all the same-album songs into one parent (the album) and all the same-artist albums into one parent (the artist). Here is the screenshot of the software: Screenshot.pnghttp://www.dotphoto.com/Go.asp?l=42khamthienP=35183166AID=6391002IID=250817449 The problem here is, as you can see, I could not insert the albums with the same artist under that artist, and songs with the same album under that album. I wonder how can I achieve this? I tried to create a GtkTreeIter to iterate through the tree and compare the name of artist/album in the TreeStore with the artist/album I got from the stream but that did not help. Can anyone suggest any better way? Thank you for reading my message! I hope you guys have a good weekend!

How to show song's information into GtkTreeView?
Hello everybody, I am trying to develop a small music manager using GTK+ and GStreamer. However, I am currently unable to display the stream information (like artist, title, album, etc...) on the GtkTreeView. I do not know if anyone here has any experience developing software like this. But the idea behind this software is that when you click File - Open and then choosing a file from the GtkFileChooser, that music file will be imported into the GtkListStore. Attached with this email is the source code of the program. I think the problem relates to either GstTagList I used or GtkListStore. Thank you for helping me with this problem.

Re: gtk-list Digest, Vol 86, Issue 9
Thank you Victor! I have written a recursive function to read all the
directories and files.
#include gtk/gtk.h
void read_all_files(const gchar* file) {
GDir *dir = g_dir_open(file, 0, NULL);
while ((file = g_dir_read_name(dir))) {
if (!g_file_test(file, G_FILE_TEST_IS_DIR)) {
g_print(%s was opened\n, file);
}
else {
read_all_files(file);
}
}
}
However, it seems that this function still only reads the 1st level of
subdirectory and print out all the files there and not reading any file at
2nd, 3rd, 4th, etc... levels. Do you have any suggestion on how to improve
this function so that it will import every single file and all subfolders
nested deeply inside the main folder?

Hello everybody,
I am trying to develop a music manager that lets the users import all audio
files from a folder. That folder may contain many subfolders, and each
subfolder may contain many files. I know that I need to create a
GtkFileChooser Dialog with GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER enabled so
that the user can choose folders instead of files.
However, I do not know how to make this GtkFileChooser selects/imports all
the files available in that directory (not only the files that are shown in
the GtkFileChooser but the files that are deeply contained inside
subfolders).
Thank you for reading my questions! I hope you guys have a good day!
