Re: [Tutor] adjust key bindings
Luke,
Thanks for the response. I am trying to help someone out on the Pygtk
list. I forgot to enclose his reasons for wanting to assign the key
press. They are below: It looks like he likes his keys set out in a
certain way. I am happy with mine the way they are! I used z in
isolation just to get the logic right. I know I can assign a function
to Z and make the Treeview move down one row and select the row below
but I don't want to have to do this for all the different buttons. I am
trying to do it without having to assign and call a whole load of
different functions.
I just start to use pygtk ... so it is just my first
question :-)
I would like to create a small file manager based on 'lfm' (curses
based file manager). I used glade for the gui and I am able to display
the existing files and directories using two treeview widgets.
Now, at the beginning I am kind of stuck with the key bindings. In
'lfm'
it was pretty easy to define special key bindings:
keytable = {
# movement
ord('p'): 'cursor_up',
ord('k'): 'cursor_up',
ord('K'): 'cursor_up2',
ord('P'): 'cursor_up',
curses.KEY_UP: 'cursor_up',
ord('n'): 'cursor_down',
ord('j'): 'cursor_down',
ord('J'): 'cursor_down2',
ord('N'): 'cursor_down',
curses.KEY_DOWN: 'cursor_down',
curses.KEY_PPAGE: 'page_previous',
curses.KEY_BACKSPACE: 'page_previous',
0x08: 'page_previous', # BackSpace
0x10: 'page_previous', # Ctrl-P
curses.KEY_NPAGE: 'page_next',
ord(' '): 'page_next',
0x0E: 'page_next', # Ctrl-N
curses.KEY_HOME: 'home',
0x16A: 'home',
ord('H'): 'home',
0x001: 'home',
curses.KEY_END: 'end',
ord('G'): 'end',
0x181: 'end',
0x005: 'end',
ord('h'): 'cursor_left',
ord('l'): 'cursor_right',
curses.KEY_LEFT: 'cursor_left',
curses.KEY_RIGHT: 'cursor_right',
ord('g'): 'goto_dir',
0x13: 'goto_file', # Ctrl-S
0x14: 'tree', # Ctrl-T
ord('0'): 'bookmark_0',
ord('1'): 'bookmark_1',
...
with such a keytable I am able to bind different 'def's to every
existing key. As you can see, I like it a lot to use 'vim-like' keys
for moving around; 'j' and 'k' to move a row up and down. In glade I
found those 'accelerators', but it is just for certain functions.
Does anyone have an idea about using such a keybinding in
pygtk? Would be nice!
I have attempted to answer his question but I am not sure I am on the
right track. Is there a better way to do it?
Regards,
John.

I highly doubt that what you want to do when someone hits a 'z' is to
generate a 'down' keypress.
What if the user assigned the down key to z?
then you'd have a
z - down - z - down - infinite loop.
What I expect you want is that each key, z and down, perform the same
action.
In other words, they both call the same function.
So basically what you'd want is something like this (non-pyGTK specific
code)
def aFunc():
print Hello, World!
bindKey = {'down':aFunc}
keypress = raw_input(What keypress do you want to perform?)
bindKey[keypress]()#this will call the 'aFunc' function if they type
'down', otherwise, it'll probably crash.
bindKey['z'] = aFunc
bindKey['z']()# now performs the same function as
bindkey['down']()#this does.
If you really do want to generate 'down' keypresses when someone hits
'z', please explain why, and I will try to the best of my abilities to
help you in that regard!
Good Luck!

Fabian,
I have had a go at binding the z key to the down cursor key. I can
block the Z key press and assign the down cursor key press and print
out the down key press but I can't redirect the signal back to the
widget. I have enclosed the code below, maybe someone else on the list
can finish off the code.
The code below assumes that you have a window in Glade with one treeview
widget. Both widgets have the key_press_event assigned in glade.
import shutil
import pygtk
import findgtk
import gtk
import gtk.glade
import gobject
import os
import sys
class Shopcard:
def __init__(self):
self.wTree = gtk.glade.XML (project12.glade, window1)
dic={on_window1_delete_event : self.quit100, }
self.wTree.signal_autoconnect (dic)
tree1 = self.wTree.get_widget(treeview1)
windy = self.wTree.get_widget(window1)
tree1.connect(key_press_event,self.callback3000,tree1,windy)
model = gtk.TreeStore(gobject.TYPE_STRING, gobject.TYPE_STRING)
self.hostmodel = model
host_inter=self.insert_row(model,None,test,'Test')
host_inter=self.insert_row(model,None,test1,'Test')
host_inter=self.insert_row(model,None,test2,'Test')
host_inter=self.insert_row(model,None,test3,'Test')
host_inter=self.insert_row(model,None,test4,'Test')
tree1.set_model(model)
renderer=gtk.CellRendererText()
column=gtk.TreeViewColumn(Col1,renderer,text=0)
column.set_resizable(True)
tree1.append_column(column)
renderer=gtk.CellRendererText()
column=gtk.TreeViewColumn(Col2,renderer,text=1)
column.set_resizable(True)
tree1.append_column(column)
def insert_row(self,model,parent,firstcolumn,secondcolumn,
thirdcolumn=None):
myiter=model.insert_after(parent,None)
model.set_value(myiter,0,firstcolumn)
model.set_value(myiter,1,secondcolumn)
if thirdcolumn !=None:
model.set_value(myiter,2,thirdcolumn)
return myiter
def callback3000(self,widget,event,tree1,windy):
import re

## fixme: missing comma, and cutpaste
key = gtk.gdk.keyval_name (event.keyval)
ONLYDIGITS=([0-9.,z]|BackSpace|Left|Right|F1|period|Tab|Up|Down)
if not re.match (ONLYDIGITS, key):
print True
return True
else:
if key == z:
tree1.emit_stop_by_name(key_press_event) # This blocks
the signal from the key press
event = gtk.gdk.Event(gtk.gdk.KEY_PRESS)
event.keyval = 65364 # This is the code for the down key
event.state = gtk.gdk.CONTROL_MASK
event.time = 0 # assign current time
print gtk.gdk.keyval_name(event.keyval)
tree1.emit('key_press_event', event)
tree1.connect(key_press_event,self.callback3001)
else:
print event.keyval
print else
return False
def callback3001(self,widget,event):
import re
prevents the possibility of inputting wrong chars
## fixme: missing comma, and cutpaste
key = gtk.gdk.keyval_name (event.keyval)
print key
print made it
ONLYDIGITS=([0-9.,z]|BackSpace|Left|Right|F1|period|Tab|Up|Down)
if not re.match (ONLYDIGITS, key):
print True2
return True
def quit(self,obj):
gtk.main_quit()
sys.exit(1)
def quit100(self,obj,wind):
gtk.main_quit()
sys.exit(1)
if __name__ == '__main__':
Shopcard()
try:
gtk.threads_init()
except:
print No threading was enabled when you compiled pyGTK!
import sys
sys.exit(1)
gtk.threads_enter()
gtk.main()
gtk.threads_leave()
The code outputs the following:
When you hit the down cursor it prints:
65364
else
and when you hit the z key it prints:
Down
65364
else

John.
