Message #00319
faster creation of notes
Hello:
In my process of learning python + gtk, I've created a zim mock up to
try out a concept. The idea is to make creation of notes a bit faster,
to achieve mind-map speed, but keeping the current treeview used in zim.
This is how it works:
* Use arrows to move in the treeview, enter to select a note and
control+space to switch to the editor and back, as usual
* Use alt+arrows to create notes within the TreeView, using the
editable property of this widget. (alt+left for children, alt+down for
sibling)
* When there are children of the Template folder, if a new note is
created, you might type the template name and hit enter. Then the text
from the template is copied to the new note, and the cell will become
editable one more time so that you can introduce the real name of this note.
There are two files attached (unless trimmed by the mail manager, in
which case you can copy and paste the files at the end of the email). It
is run by writing:
python zimmindmap.py
The other file was generated by glade: it is a gtkbuilder file and it
doesn't need any libraries. It has a mock up menu which is totally
useless, and probably in spanish. The template part should really be
better with autocompletion, and maybe it should use grandchildren of the
Templates folder into, but anyway this is just a mockup.
Do you like this way of creating notes, and/or using Templates?
Regards
