Hi all,
I'm just wondering but when i try to access/update anything on my Tkinter GUI
from one particular function, my whole program crashes/freezes with no error.
The function is part of a class which handles all the GUI drawing/event
handling etc.
The function in question gets called from a win32 DesignatedWrapPolicy class.
Sample code below:
[code]
# this function is part of an IDropTarget class, the TargetWidget was
definined in the __init__ method of this functoin and it points to my class
which handles the GUI.
def Drop(self, data_object, key_state, point, effect):
data = data_object.GetData((15, None, 1, -1, 1))
print data
n_files = shell.DragQueryFileW(data.data_handle, -1)
print n_files
filenames = [shell.DragQueryFileW(data.data_handle, n_file) for n_file
in range(n_files)]
print filenames
self.TargetWidget.filesDropped(filenames) # this calls the filesDropped
function of the TargetWidget class and passes the filename list to it.
# this function is part of the GUI class (which inherits from
Tkinter.Toplevel) the print commands work however if i uncomment the clearInput
function (which just calls self.filepathInput.delete(0, END) to clear the text)
# the program hangs, same for the second commented line, and anything else
that requires a call to tk it appears. Is there some sort of conflict going on
between win32 and Tk ??
def filesDropped(self, fileList):
print fileList
# self.clearInput()
# self.filepathInput.insert(Tkinter.END, fileList[0])
[/code]
I'm just wondering if there's something i need to do to 'release' the GUI?
I'm pretty sure it's got nothing to do with my code elsewhere because it was
all working smoothly before, and if i call the filesDropped function from
somewhere else (not from the IDropTarget class) i don't have any issues.
Thanks in advance,
Alex
