Re: [PyQt] From/Import, proper namespace,etc
Thanks Phil,
...(yes, I see the design flaw you speak of...was doing a bit of testing)
Just to add for prosterity,...your answer had a small typo...just needs a
".connect"
statement in thereso for others who may find this later,..the statement
is:
self.button.clicked.connect(lambda checked: DoTest2(self))
I did find another method (better design? dunno ;-) and that is to have the
button connect
statement call a local (in file A) function which in turn calls B.function()
Using,
from B import *
.
self.Button_02.clicked.connect(self.DoTest1)
def DoTest1(self):
print("DoTest1")
status = DoTest2(self)
print status
Thanks again,

[PyQt] From/Import, proper namespace,etc
I think I figured this out once, lol...but can't seem to recall...
Consider you have two python files,..."a" and "b"...where you "launch a" and
"import b".
But inside "b" is a PyQt call back to a control defined in "a". I keep
getting a "not defined" error...
So,...
===
File "A"
===
#!/usr/bin/env python
import os
import sys
from PyQt4 import QtCore, QtGui, uic
*from b import **
class MainWindow(QtGui.QMainWindow):
def __init__(self, parent=None):
super(MainWindow, self).__init__(parent)
self.setGeometry(520, 285, 640, 480)
self.Button = QtGui.QPushButton(self)
self.Button.setGeometry(QtCore.QRect(105, 140, 151, 66))
self.Button.setObjectName("Button")
self.Label = QtGui.QLabel(self)
self.Label.setGeometry(QtCore.QRect(350, 250, 101, 21))
self.Label.setObjectName("Label")
self.Button.setText("Test 1")
self.Label.setText("AAA")
self.Button.clicked.connect(DoTest2)
def main():
app = QtGui.QApplication(sys.argv)
global form
form = MainWindow()
form.show()
app.exec_()
if __name__ == '__main__':
main()
=
and File "B"
=
#!/usr/bin/env python
def DoTest2(self):
print("DoTest2")
*self.Label.setText("BBB")*
return("Done")
==
So,...to launch
prompt>> python a.py
Then, hit the button...the button calls a function in File-B, which tries to
modify text in a Label that
is defined in File-A.
prompt -> python a.py
DoTest2
Traceback (most recent call last):
File "b.py", line 7, in DoTest2
self.Label.setText("BBB")
AttributeError: 'bool' object has no attribute 'Label'
So,..what's the proper way to do this?...I've tried every which way but
nada...
Thank you,

Re: [PyQt] need to install multiple versions of PyQt on each laptop at work
...understood, Thanks... Btw,...just for prosterity, The install went pretty well...on WinXP 32bit, 1) Installed newer version of Python (2.7) 2) Checked Env variables,etc. 3) Installed Qt Libs (minGW) only with downloaded installer (4.7.1) 4) Checked Env variables.etc 5) ran "qtvars.bat" ( or it won't compile correctly) 6) Installed Sip, adding extra flag arg ( --platform win32-g++ ) 7) installed PyQt4 (4.9.1) normally Now what was curious,...is that when I went to use, it err'd out, saying it could not perform the command "import PyQt4.QtCore" ...saying couldn't find DLL. So, to test, I copied cp C:/Qt/4.7.1/bin/*.dll C:/Python27/Lib/site-packages/PyQt4/ and then everything worked... And to add to Phil's note of caution above...when using one version or the other, you'll need to modify at least one (I do more than one) environment variable.. So, when I go back and forthI check and modify PATH PYTHONPATH QTDIR If you're using a shell environment like Cygwin, then this can be done at the individual shell window level, but that'll be only temporary.

[PyQt] Text "write on" effect
okay, this may seem a bit superfluous, but would be a very nice animation
effect to have in one's toolbox..
For those that don't know what a "write on" animation is,...you probably see
them on TV everyday,..
but it's when a whole sentence is displayed a character at time, with just a
fraction of a second delay
in-between each character...
Thought this would be trivial at first,...but there's something going on in
Qt that senses there's about to
be a bunch of fast updates, so it waits until everything is done and updates
*once*, which defeats the
purpose
Here's how the madness unfolds,..
text = "Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam
nonummy nibh euismod tincidunt ut laoreet"
accum = QString("")
for i in range(0, len(text)):
accum = accum + text[i]
self.label.setText(accum)
self.label.update()
sleep(.1)
So, I accumulate the string char by char calling update() and sleep() at
each interval,...a button triggers this function.
But instead of seeing the effect progress as expected, it just display the
whole string at once...
Anybody got any ideas how to achieve this effect ?
I've attached a short example script...
Cheers,
Jim

Re: [PyQt] QDockWidget issue in Linux, but not Windows, OSX
Hey Pete, Well I did try your technique, but the problem still exists. As I said, it's my bad that the example I gave you, while showing the bug, was not totally representative of the real program. I figured that solving it on a small scale, if you will, would yield a solution that would work in the real thing. Unfortunately, and like you said, kinda' rare, that it doesn't. I'm in the process of creating a more simpler version of the larger program, that won't be as simple as the first, lol...but more complex, so that if you or someone finds a solution, then it'lll have a greater chance of mapping over to the real thing. Thanks again for your help and input on this,...I will post a new example script as soon as possible, Cheers, Jim -- View this message in context: http://python.6.n6.nabble.com/QDockWidget-issue-in-Linux-but-not-Windows-OSX-tp4374122p4466862.html Sent from the PyQt mailing list archive at Nabble.com. ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
Re: [PyQt] QDockWidget issue in Linux, but not Windows, OSX
Thanks for your help, Pete While your example does indeed fix the problem that my example code showed, unfortunately, when plugging it in to the real program, the problem persists. However, I have been able to reproduce this bug using just Designer. On Windows here,...run Designer Create a MainWindow (default one do) Drop in a QFrame and pull it to just shy of MainWindow Drop in a QDockWidget Select dockWidget Cut Select QFrame Paste and then "run it" doing a Form->Preview, ...clicked "undock" button, behaviour is Normal Did the same thing on Linux, but when I click the "undock" button, the button is stuck at top, just like our problem. Can anyone else confirm this on Linux ? So that's definitely gotta be a Qt bug, right? Any advice about how to fix ?

[PyQt] QDockWidget issue in Linux, but not Windows, OSX
I have a really weird phenomena here, and am hoping somebody can shed some light on this... Before posting code, thought I would briefly describe,... Using a treeWidget, expanding an item presents us a tableWidget whose parent is a tabWidget, whose parent in turn is a dockWidget,... dockWidget | tabWidget | tableWidget In Windows and OSX, undocking the dockWidget, results in normal behaviour, It is moveable, closeable, and floatable. However, in Centos5.6 Linux, when doing same, the dockWidget un-docks normally, and shows correct data, but it is *un-moveable* (This is same code as from Win,OSX) It is *hard* docked to top of OS window manager, but I can see the titleBar of the dockWidget. Using Alt-F7->Move, the dockWidget window can be moved, and now acts normally. I searched documentation and the internets, but can't resolve... Anyone have any ideas on this one? Thanks!
