I have the following code - which is started by a button - say button1 which has to happen every one second -through a thread.
self.pump_rpm_text_control.AppendText(str(self.sheet_num.cell_value(self.sel+1,10)*(SortAndDecode(self.data, 'FrqQ5'))/65536))`
The problem I am facing here is - the "self.sel" is recorded from an excel sheet - when a selection from an excel sheet happens.
So I decided to write an if condition something like this:
if not self.OnList():
self.pump_rpm_text_control.AppendText("000")
else:
self.sheet_num.cell_value(self.sel + 1, 10)
self.pump_rpm_text_control.AppendText(str(self.sheet_num.cell_value(self.sel+1,10)*(SortAndDecode(self.data, 'FrqQ5'))/65536))
OnList - is the event that is called when a selection is being made on a listbox. But however my code is still going to ELSE, even though my OnLIST event has not happened. Any help would be greatly appreciated.
In the same way that this code follows the else path?
>>> def Onlist():
... return True
...
>>> if not Onlist():
... print False
... else:
... print True
...
True
It all depends on what value Onlist returns as furas commented

I am trying to call the startagain function within the onclick event handler. The function does execute the input statement but does not allow the user to enter a response, the program just terminates.
import turtle
wn = turtle.Screen()
#Event Handler
def clicked(x,y):
print(x,y)
startagain()
#Start over
def startagain():
again = input("Want to start over? ")
if again == "y":
print("okay")
#The event
wn.listen()
wn.onclick(clicked)
wn.mainloop()
I'm not sure if I need to somehow stop the screen from listening or if there is another approach to this. Any help would be appreciated.
Your code works for me as-is. However, I would make two changes. First, I would have clicked() call startagain() indirectly via ontimer() (with no time delay), so that we don't end up with multiple clicked() calls on our stack. I would also obtain input via textinput() rather than switch back to the console for input:
from turtle import Screen, Turtle
# Event Handler
def clicked(x, y):
screen.ontimer(startagain)
# Start over
def startagain():
again = screen.textinput("Game Over", "Want to start over? ")
if again and again.lower().startswith("y"):
print("okay")
# The event
screen = Screen()
screen.onclick(clicked)
screen.mainloop()
I'm using AutoIt and SciTE to create an installation script. The problem I am running into is that there is a tree menu for selection of features. I can select the whole treeview (SysTreeView32), but am not sure how to get inside it to check the boxes without doing a mouse move and click (not a great option).
The Treeview looks like this:
The Control Info from AutoIT is like this:
I'm sure it is possible, just can't figure out how to do it. This is my first attempt a such a script. Creating a response file does not work for this exe for some reason. So - this appears to be my only way out to create a somewhat silent install (not silent anymore, but at least automated).
* EDIT - Current State of Things *
I did figure out how to do some of this, but I still can't figure out if the items is selected before accessing it. So - since it toggles, I could be turning off a feature I want!
$hWnd = WinWaitActive($WindowTitle, 'Select Features')
$tvCtl = ControlGetHandle($WindowTitle, '', 'SysTreeView321')
$firstItem = _GUICtrlTreeView_FindItem($tvCtl, 'eBooks')
_GUICtrlTreeView_SelectItem($tvCtl, $firstItem, $TVGN_FIRSTVISIBLE)
_GUICtrlTreeView_ClickItem($tvCtl, $firstItem, "left", True, 1)
Send('{SPACE}')
I wouldn't think I would have to send the space since I sent the ClickItem, but seems so.
I could also do this:
ControlTreeView($hWnd, '', $tvCtl, 'Select', '#0')
ControlSend($hWnd, '', $tvCtl, ' ')
That will toggle the first one. So - i can count them all up and do it that way.
But when I check for "IsEnabled" or "IsChecked", it always says NO. So - I can't check the ones I need only. I have to hope their status is what I expect.
Here is how I am checking "IsChecked" and "IsEnabled":
If ControlCommand($hWnd, '', $logTool, 'IsEnabled') then
ConsoleWrite('Log Tool - IsEnabled' & #CRLF)
Else
ConsoleWrite('Log Tool - NOTEnabled' & #CRLF)
EndIf
and
If ControlCommand($hWnd, '', $logTool, 'IsChecked') then
ConsoleWrite('Log Tool - IsChecked' & #CRLF)
Else
ConsoleWrite('Log Tool - NOTChecked' & #CRLF)
EndIf
It always comes back NOTEnabled and NOTChecked. I made sure that I ran the same procedure above: FindItem, SelectItem, ClickItem. And, the correct item is highlighted/selected when this procedure is run - I can see that. So - it just isn't returning a proper value.
Opt('WinTitleMatchMode', 2)
$hWnd = WinGetHandle("InstallShield Wizard") ; Notice the correct title
$hTree = ControlGetHandle($hWnd, '', "[CLASS:SysTreeView32;INSTANCE:1]")
; == Now you can interact with the treeview with functions from "GuiTreeView.au3"
EDIT:
Try this
; Select the item so:
_GUICtrlTreeView_SelectItem($hTree, $hItem, $TVGN_CARET)
; Get checked state:
_GUICtrlTreeView_GetChecked($hTree, $hItem)

I have a dexterity content type (my.product.myobject) that uses the IEventBasic behavior (implemented in the xml file with other behaviors) and I'm trying to make the end field be set within the same week of the start field. I attempt to correct the end date in an IObjectAddedEvent (zope.lifecycleevent.interfaces.IObjectAddedEvent).
I first get the week range from the start field:
def getWeekRangeFromDate(a_date,offset=1):
start = (a_date - timedelta(days=(a_date.weekday() + offset) % 7)).replace(hour=0,minute=0)
end = (start + timedelta(days=6)).replace(hour=23,minute=59)
return {'start':start,
'end':end,
}
def myObjectAdded(myObject, event):
week_range = getWeekRangeFromDate(myObject.start)
if myObject.end > week_range['end']:
myObject.end = week_range['end']
I have the end field printed in the browserview and I use IEventAccessor to extract the end date from the myObject:
class View(BrowserView):
def __init__(self,context,request):
...
self.context = self.context
def getFormattedEnd(self):
if self.context.whole_day == False:
return IEventAccessor(self.context).end.strftime('%m/%d %I:%M %p')
...
When it doesn't need to be programmatically corrected, the end field displays correctly, but when it does, it appears 5 hours off.
In my myObjectAdded event, I tried:
if myObject.end > week_range['end']:
myObject.end = week_range['end'] - timedelta(hours = IEventAccessor(myObject).end.offset().total_seconds()/3600)
This does appear right actually, but when I go to the edit form and change the start field, the end field ends up changing itself seemingly random. Changing the starting hour field to 16 changed the end's month about two weeks ahead.
How can I set it without it acting up? Am I misundertanding how to use IEventBasic?
Edit: I'm coming across something really interesting. In the edit form, the Start End Validator is failing.
Event Starts - 25/November/2016 9:00
Event Ends - 25/Novermber/2016 20:00
I click submit and the status message says End date must be after the start date.
Edit: The version of Plone I am using is 4.3.
In IPython Notebook / Jupyter, arrow up/down keystrokes within a cell are handled by CodeMirror (as far as I can tell). I use these actions a lot (re-bound to control-p / control-n) to move between cells; but at the end of every cell, the cursor moves to end of line first before jumping to the next cell. This is counter-intuitive and, to me, rather distracting.
Is there any way to configure CodeMirror to make this move down to be just that - a move down?
Thanks!
The moving-to-next-cell behavior is defined by IPython wrapper code, which probably checks whether the cursor is at the end of the current cell, and overrides the default CodeMirror behavior in that case. You'll have to find that handler and somehow replace it with one that checks whether the cursor is on the last line. (I don't know much about IPython, only about CodeMirror, so I can't point you at the proper way to find and override the relevant code. They might have bound the Down key, or they might have overridden the goLineDown command.)
Knowing that I wasn't alone in wanting to skip the "going to end of line" behavior when going down from the last line of a code cell, I investigated that behavior and found out that:
it's CodeMirror that goes to the end of line when you type down in the last line of a code cell (file: codemirror.js ; "methods": findPosV and moveV)
and it's IPython that decides what to do with the "down" event after it has been handled by CodeMirror (file: cell.js ; class: Cell ; method: handle_codemirror_keyevent) ; looking at the code, I saw that IPython ignores the event when not at the last character of the last line.
This essentially confirms Marijin's answer.
The primary goal being to jump to the next cell, I think there's no need to prevent CodeMirror from going to the end of that line. The point is to force IPython to handle the event anyway.
My solution was to change the code from Cell.prototype.handle_codemirror_keyevent to this:
Cell.prototype.handle_codemirror_keyevent = function (editor, event) {
var shortcuts = this.keyboard_manager.edit_shortcuts;
var cur = editor.getCursor();
if((cur.line !== 0) && event.keyCode === 38){
// going up, but not from the first line
// don't do anything more with the event
event._ipkmIgnore = true;
}
var nLastLine = editor.lastLine();
if ((event.keyCode === 40) &&
((cur.line !== nLastLine))
) {
// going down, but not from the last line
// don't do anything more with the event
event._ipkmIgnore = true;
}
// if this is an edit_shortcuts shortcut, the global keyboard/shortcut
// manager will handle it
if (shortcuts.handles(event)) {
return true;
}
return false;
};
This code provides the desired behavior for the "down-arrow" key (almost: the cursor still goes to the end of the line, except that we don't see it, as we're already in another cell at that point), and also handles the "up-arrow" key similarly.
To modify the handle_codemirror_keyevent prototype, you have two possibilities:
You edit the cell.js file and change the code of the prototype to the code I gave above. The file is in <python>/Lib/site-packages/IPython/html/static/notebook/js or something similar depending on you distro
Much better, after the page is loaded, you change that prototype dynamically by doing this:
IPython.Cell.prototype.handle_codemirror_keyevent = function (editor, event) {
<same code as above>
};
You can do that in your custom.js for example, or create an extension to do it (that's what I did).
I pretty new in this whole Python thing and my question is how to make, that a button runs the command, when clicking it and not before.
I searched much in the Internet but i didnt find anything.
I dont understand the classes at all. Is there no other way to do this?
Here is my work, i did on the programm.
Thanks for your help
from tkinter import *
import os
t = ""
def ordner(x):
print ("def")
if os.path.exists(os.path.join("/Kunden/",x)) == True:
pass
else:
os.mkdir(os.path.join("/Kunden/",x))
def E1holen():
x = E1.get()
ordner(x)
#Hauptfenster
main=Tk(className='Kundendatenbank')
main.iconbitmap('icon.ico')
#Inhalt Hauptfenster
L1 = Label(main, text="Kundenname:")
L1.pack(side = LEFT)
E1 = Entry(main, bd =5, textvariable=t)
E1.pack(side = RIGHT)
a = Button (main, text=("erstellen/bearbeiten"), command=E1holen()).pack()
main.mainloop()
It runs immediately ecause you tell it to.
What is the syntax for calling a function in Python? It's foo(), right? So, when you do command=E1holen(), what should python do? It should call E1holen(), and then pass the result to the command attribute.
Put another way, the command attribute takes a reference to a function, but because of the () you were calling the function and giving the command attribute whatever that function returned. The solution? Remove the ():
a = Button(..., command=E1holen)
