how to hide popup window ?
Hi i am creating one pop-up window witch contains one widget in my main application window . i am showing this pop-up window on one button press event (in callback of button ) at current mouse position Now i want to hide this window when i press any other widget on window including main application window witch signal should i connect ( may be to main window ? ) so that single click on any widget (including main application window) will hide my pop up window in its callback function (i will write gtk_widget_hide_all(popup_window) as a function definition of it) Thanks in advanced sphurti Why delete messages?

Insert gap in text buffer by using a tag
I am having a text like "0bullet" inside of GtkTextView, where the first
character is a bullet sign and the rest is the ordinary text
I need to be able to format this text to insert some space gap between the
bullet and the rest (should look like this: "0 bullet").
I've tried using tags in 3 different ways but none of these seem to work:
a) using "indent" property:
GtkTextTag *tag1 = gtk_text_buffer_create_tag (buffer, NULL,"indent",
18,"indent-set", TRUE,NULL);
gtk_text_buffer_apply_tag(buffer, tag1, &iterBulletEnd, &iterEnd);
b) using "left-margin" property:
GtkTextTag *tag1 = gtk_text_buffer_create_tag (buffer, NULL,"left-margin",
18,"left-margin-set", TRUE,NULL);
gtk_text_buffer_apply_tag(buffer, tag1, &iterBulletEnd, &iterEnd);
c) using "right-margin" property:
GtkTextTag *tag1 = gtk_text_buffer_create_tag (buffer, NULL, "right-margin",
18, "right-margin-set", TRUE, NULL);
gtk_text_buffer_apply_tag(buffer, tag1, &iterStart, &iterBulletEnd);
where iterStart points to the start of text, iterEnd points to the end of
text, iterBulletEnd points after the bullet sign.
Does anyone has an idea what is wrong here ?

Miroslav

Note that just a dynamic memory allocation that isn't freed before the
application terminates is not a leak, in case there still exists a way
to access that allocation through static variables (or variables local
to main()). You wouldn't call a "static int[1]" a leak, would you?
Nor should you then consider a "static int *p; main (void) { p =
malloc(1); return 0;}" a leak.
A leak, by definition, is an allocation that is done repeatedly while
the program is running, maybe while the user is performing some
repetitive task in the application, and to which no accessible pointer
remains. For an allocation to be classified as a leak the allocation
should be performed again and again from the same point in code, in a
similar context, and forgotten. All this IMHO, of course.

GtkFileChooser initial dir
Hi,
could you point me to some useful documentation or suggest me
something about:
1. storing and retrieving the initial opening/saving directory for a
GtkFileChooser; in the past I relied on the windows registry, but I'd
like to do something more GTK styled (a configuration file?)
2. retrieving the shortcuts names for "places"; I tried this way (and
another that I don't recall) but it didn't work:
dialog = gtk_file_chooser_dialog_new(title, parent, action,
GTK_STOCK_OK, GTK_RESPONSE_ACCEPT,
GTK_STOCK_CANCEL, GTK_RESPONSE_REJECT,
NULL);
GSList* shortcut_folders = gtk_file_chooser_list_shortcut_folders
(GTK_FILE_CHOOSER(dialog));
GSList* rover = shortcut_folders;
while(rover) {
gchar *temp = (gchar *) rover->data;
// I'd like to strcmp with a known "Place" shortcut but
// temp is NULL here
g_free (temp);
rover = rover->next;
}
3. is it possible to change a "volume" shortcut label, or avoid its
translation? For example Desktop is translated (in Italian, in my case)
but many dummy users are lost if they see "Scrivania" instead of
"Desktop"
Thanks a lot
Federico
