Add applying of filtering into list of files to check if we have
an active project file. Filtering is quite much similar to the
filtering in CLI.
If we have directory filter ("gui/") then we check all paths if
they contain "gui" part. In practice we search for string "/gui"
from the paths. If we have filename filtering
("gui/projectfile.cpp") then we check if any of the paths end
with that.
This patch adds support for ignored paths in the project file.
There is new <ignore> element which can contain one or more
<path> elements with name attribute containing the path to
ignore.
Handling paths in line edit control is quite hard. List control is
much more pleasant to use for it. Convert Project file path
handling to similar list control usage than include paths earlier.
Editing include directories in edit control is not nice. Instead
add new tab and list control for the include directories. They
are now added, edited and removed like global include directories
in settings dialog.
The default application was not handled correctly when removing
application from the list. If the default application is removed
then we reset the default application to unknown. Otherwise we
make sure the default application is correct after the removal of
other application.
Instead of keeping the default application as a first item in
the application list point the default application by adding a
"[Default]" text after its name.
Make the editor application settings dialog to look similar than
include paths dialog. Move buttons right to the list, not below.
And remove unnecessary "application" word from button texts.
Rename Modify-button to Edit-button since we are not modifying
the application but editing its info. Similarly rename Delete-
button to Remove-button since we are not deleting the application
but removing from the list.
Instead of hard-to-use single line edit control, use list control
for include paths. Have separate buttons for adding, editing and
removing paths. Paths are still stored as one string where paths
are separated with ";". Empty paths are ignored.
