Since GLib 2.32, messages logged with levels INFO and DEBUG aren't
output by the default log handler unless the G_MESSAGES_DEBUG
environment variable contains the domain of the message or is set to
the special value "all".
Since we use INFO level messages for verbose mode, we need to make
sure this environment variable is properly set when in verbose mode.
If the caller doesn't want the list to be sorted, there is no need to
preserve the order in which the files were actually read, since that
order is undefined anyway.
GtkLabel may re-create its PangoLayout between calls leading to the
final layout used for rendering not to be set up with the appropriate
values for our sizing. Then, re-set up the layout each time we have to
deal with it and straight before GtkLabel renders it.
Since the license is a huge piece of text expected to possibly scroll
horizontally, and since most themes display the background of text
views in a different color than the default widget background color,
adding a shadow makes the edges more visible and the UI neater.
If the 'default' style isn't set to a named style, then probably the
filetype styles have been overridden with manual colors and may not
work properly with color schemes.
Note: HTML-based filetypes won't show a warning because they don't
have a 'default' style (they use 'html_default' instead).
This is a simple heuristic, but is worth having to avoid some
spurious bug reports when using the color schemes dialog.
Current color scheme was applied upon color scheme selection dialog
display because the GtkTreeView::cursor-changed signal is emitted when
the tree view is initially shown (since it actually gets the focus for
the first time), uselessly re-applying the current color scheme.
This is a performance issue because when many documents are open
updating the color scheme can take a few seconds.
Now we watch for the GtkTreeSelection::changed signal on the tree
view's selection, which is only emitted when the selected item actually
changes. We also connect to that signal after filling the tree so we
don't get notified on the initial selection setup.
Now there is a dialog instead of a menu for selecting the color
schemes, the item under View->Editor can be created with Glade like the
rest of the menu.
This prevents GCC from complaining about implicit casts and comparisons
between different pointer types. It also makes the code a little less
bound at dealing with TMTags.
