PyGTK3 : capturing a string from keybord
I had some code written in python3 using GTK3. The program waited for some inputs from the keyboard. For instance, if I pressed 'q' the program printed a specific symbol, etc.
This code looks like
keyname = Gdk.keyval_name(event.keyval)
if keyname == 'q':
self.textbuffer.insert_at_cursor('you've pressed q')
I want to execute a callback function, when the program captures a specific string, e.g. when I press say, 'q' and 'w' in parallel (I press 'w' without leaving the key 'q') then, the program executes a specific function.
I didn't find something in GTK3, except a method called Gdk.utf8_to_string_target(event.string) but I did not manage to use it correctly. For pressing two characters such as ctrl and 'h' it's easy by using something like
ctrl = (event.state & Gdk.ModifierType.CONTROL_MASK)
if ctrl and event.keyval == Gdk.KEY_h:
self.textbuffer.insert_at_cursor('n')
I checked a seemingly similar question Detect specific keypresses in GUI, but was asking about checking if a special key is pressed. Which is not my case.
As a minimal code we provide the following.
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk, Gdk
class MyWindow(Gtk.Window):
def __init__(self):
Gtk.Window.__init__(self, title="awesome gui")
self.set_resizable(True)
self.set_default_size(700,550)
self.grid = Gtk.Grid()
self.add(self.grid)
self.create_textview()
self.create_buttons()
def create_textview(self):
scrolledwindow = Gtk.ScrolledWindow()
scrolledwindow.set_hexpand(True)
scrolledwindow.set_vexpand(True)
self.grid.attach(scrolledwindow, 0, 1, 50, 1)
self.textview = Gtk.TextView()
scrolledwindow.add(self.textview)
self.textbuffer = self.textview.get_buffer()
self.textview.set_editable(False)
self.textview.set_cursor_visible(False)
def create_buttons(self):
self.button1 = Gtk.Button(label="Clear text")
self.button1.connect("clicked", self.on_button1_clicked)
self.grid.attach(self.button1, 0, 0, 1, 1)
self.button2 = Gtk.Button(label="Start capturing")
self.button2.connect("key-release-event", self.on_key_release)
self.grid.attach_next_to(self.button2,self.button1,
Gtk.PositionType.RIGHT, 1, 1)
def on_button1_clicked(self, widget):
self.textbuffer.set_text('')
def on_key_release(self, widget, event, data=None):
keyval = event.keyval
keyname = Gdk.keyval_name(keyval)
ctrl = (event.state & Gdk.ModifierType.CONTROL_MASK)
if keyval == Gdk.KEY_space:
self.textbuffer.insert_at_cursor(' ') #space
if keyname == 'q':
self.textbuffer.insert_at_cursor('you pressed q')
# etc..
if ctrl and keyval == Gdk.KEY_h:
self.textbuffer.insert_at_cursor('n') #change line when ctrl + h is pressed
win = MyWindow()
win.connect("destroy", Gtk.main_quit)
win.show_all()
Gtk.main()
My question is, If I can have something like
#you press q and after w or w and after q or the same time you press q and w
if keyname == 'qw':
self.textbuffer.insert_at_cursor('you pressed qw')
Any ideas? Please, if it is possible provide some code to prove your point!

it connects a key and a key-mod (https://github.com/bstpierre/gtk-examples/blob/master/c/accel.c)
if you really want to capture a string then you could try recreating the function given in gtk_accel_group
