RE: [pygtk] Re: adjust key bindings
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.

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)

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

Sandro,
That's exactly what I need.
Thanks,
John.

If you don't return True, default callback will be called that insert
the 'a'.
I have something like this:
def digits_check_input_cb(self, widget, event):
"""prevents the possibility of inputting wrong chars"""
## fixme: missing comma, and cut&paste
key = gtk.gdk.keyval_name (event.keyval)
ONLYDIGITS="([0-9.,]|BackSpace|Left|Right|F1|period|Tab|Up|Down)"
if not re.match (ONLYDIGITS, key):
return True
Not sure whether this is the best way thought...

[pygtk] key_press_event
Hi,
I'm using Python 2.4, pygtk and Glade2.
I have a few text entries. I am trying to put validation on the text
entry boxes. I am trying to catch the key_press_event, check the key
that has been pressed and either allow it or put back the old text. The
code is below with the output after it.
class Test:
def __init__(self):
self.wTree = gtk.glade.XML ("test.glade", "window1")
dic={"on_window1_delete_event" : self.quit10, }
self.wTree.signal_autoconnect(dic)
cancel = self.wTree.get_widget("button2")
cancel.connect("clicked", self.quit, )
text1 = self.wTree.get_widget("entry1")
text2 = self.wTree.get_widget("entry2")
text2.connect("key_press_event",self.callback3)
login = self.wTree.get_widget("button1")
login.connect("clicked", self.callback2, text1,text2)
def callback3(self,data,widget):
input = data.get_text()
print input
data.set_text("test")
def callback2(self,data,text1,text2):
print 'hello'
def quit10(self,obj,data):
gtk.main_quit()
sys.exit(1)
def quit(self,obj):
gtk.main_quit()
sys.exit(1)
if __name__ == '__main__':
Test()
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 box starts of with 123 in it. If I hit the 'a' key on the key board
I get the following result.
123 is printed and 'atest' appears in the text entry box.
Is there a way to catch the key_press (in this case the 'a') and check
to see if it is a number. If it is not a number, ignore it. If it is a
number accept it.
Why does the 'a' appear in 'atest'. It is like the code works first,
sets the text to 'test' and then the key press works and inserts the
'a'. Do I need to disconnect the key press signal?
Thanks,
John.

[pygtk] FW: [Tutor] Help me make it look pretty!
Good evening all. I am writing a program using python 2.4, glade 2 and pygtk. It takes input from the user using textentry boxes. The input should be a number. When the user keys the data in, it automatically left justifies. The function below, takes the input for four boxes and right justifies it by using an ugly, string format. The boxes are 45 characters big, so I use the len function to fit them into the box. The code is below. I am looking for a way to set the text entry up, so that there is a decimal point in the box regardless of what the user does and I am also looking for a way to keep the numbers right justified. Any suggestions or comments as always are greatly appreciated. Regards, John. def callback36(self,data,text37,text38,text39,text40,text41,text42,label): a = text37.get_text() b = text38.get_text() c = text39.get_text() d = text40.get_text() a= float(a) b= float(b) c= float(c) d= float(d) try: e = float(a + b + c + d) g = e/a e = "%0.2f" % e g = "%0.2f" % g g = str(g) label.hide() e = " %s" % e a = " %s" % a b = " %s" % b c = " %s" % c d = " %s" % d g = "%s%%" % g text42.set_text(str(g)) if len(e)>45: x = len(e) - 45 x = x + 4 y = e[x:] text41.set_text(str(y)) return else: text41.set_text(str(e)) return except: label.show() return ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
[pygtk] 2 Combo Boxes! What was I thinking?
Hi,
I have set up a GUI which has amongst other widgets two
combo boxes. I am using:
PythonCard version: 0.8.1
wxPython version: 2.6.1.0
Python version: 2.4.1 (#65, Mar 30 2005, 09:13:57) [MSC v.1310 32 bit (Intel)]
Platform: win32
Glade 2
I started by setting up comboboxentry2 to accept two
settings in its drop down list.
(open + closed). This worked
fine. Code below:
self.wTree = gtk.glade.XML ("phonelog.glade",
"window1")
dic={"on_window1_destroy" : self.quit, }
self.wTree.signal_autoconnect (dic)
combo1 = self.wTree.get_widget("comboboxentry2")
combo1.append_text("Open")
combo1.append_text("Closed")
combo1.set_active(0)
combo1.connect("changed", self.callback2, combo1)
My problems started when I went to set up
comboboxentry3. I used the
following code:
self.wTree = gtk.glade.XML ("phonelog.glade",
"window1")
dic={"on_window1_destroy" : self.quit, }
self.wTree.signal_autoconnect (dic)
combo3 = self.wTree.get_widget("comboboxentry3")
combo3.connect("changed", self.callback3,
"comboboxentry3")
combo3.append_text ("Mon")
combo3.append_text ("Tue")
combo1 = self.wTree.get_widget("comboboxentry2")
combo1.append_text("Open")
combo1.append_text("Closed")
combo1.set_active(0)
combo1.connect("changed", self.callback2, combo1)
I got the
following error:
Gtkwarning: gtk_combo_box_append_text: assertion
GTK_IS_LIST_STORE(Combobox->Priv->Model)
Failed
Combo3.append_text(“Mon”)
Gtkwarning: gtk_combo_box_append_text: assertion
GTK_IS_LIST_STORE(Combobox->Priv->Model)
Failed
Combo3.append_text(“Tue”)
I then tried the code:
self.wTree = gtk.glade.XML ("phonelog.glade",
"window1")
dic={"on_window1_destroy" : self.quit, }
self.wTree.signal_autoconnect (dic)
combo3 = self.wTree.get_widget("comboboxentry3")
combo3.connect("changed",
self.callback3, "comboboxentry3")
combo3.child.append_text ("Mon")
combo3.child.append_text ("Tue")
combo1 = self.wTree.get_widget("comboboxentry2")
combo1.append_text("Open")
combo1.append_text("Closed")
combo1.set_active(0)
combo1.connect("changed", self.callback2, combo1)
I get the
following error message:
DeprecationWarning: use GtkEditable.insert_text
Combo3.child.append_text(“Mon”)
DeprecationWarning: use GtkEditable.insert_text
Combo3.child.append_text(“Tue”)
The combobox3 is populated on the GUI but instead of being a
drop down list it appears as a string on one line and looks like this:
MonTue
I have to confess I am not really sure what I am doing. I just guessed at putting the child
command in. It gets me close but
not close enough. Can anyone tell
me what I am doing wrong or explain what happens when you put two combo boxes
on the one GUI?
Any help greatly appreciated.
Thanks,
John.
