Building tkinter on Windows
Hello. Can anyone tell me how to build tkinter on Windows? I've downloaded the source, ran Tools/buildbot/external.bat to build the external dependencies. I copied tcl85g.dll and tk85g.dll to PCBuild. I built the Visual Studio solution. Everything built fine without errors. Everything seems to work except tkinter. It says: Traceback (most recent call last): File "", line 1, in File "...\cpython-idle\lib\tkinter\__init__.py", line 36, in from tkinter import _fix File "...\cpython-idle\lib\tkinter\_fix.py", line 65, in import _tkinter ImportError: DLL load failed: The specified module could not be found. I'm thinking I didn't put the DLLs in the right place, but I don't have any idea where to put them and Google isn't helping. -- https://mail.python.org/mailman/listinfo/python-list
Logical error in filling QTableWidget and filling all of nodes
Dear All, I have the following code (PyQt): / searchFrameObject.tableWidget.setRowCount(rowCounter) searchFrameObject.tableWidget.setColumnCount(5) for row in range(rowCounter): for column in range(5): for result in query: item = QtGui.QTableWidgetItem(_fromUtf8(result.name)) item.setFlags(item.flags() ^ QtCore.Qt.ItemIsEnabled) searchFrameObject.tableWidget.setItem(row,column,item) #item = QtGui.QTableWidgetItem(String(result.bought_price)) #item.setFlags(item.flags() ^ QtCore.Qt.ItemIsEnabled) #searchFrameObject.tableWidget.setItem(row,column+1,item) #item = QtGui.QTableWidgetItem(result.bought_date) #item.setFlags(item.flags() ^ QtCore.Qt.ItemIsEnabled) #searchFrameObject.tableWidget.setItem(row,column+2,item) item = QtGui.QTableWidgetItem(result.stock) item.setFlags(item.flags() ^ QtCore.Qt.ItemIsEnabled) searchFrameObject.tableWidget.setItem(row,column+3,item) item = QtGui.QTableWidgetItem(result.minimum_bound) item.setFlags(item.flags() ^ QtCore.Qt.ItemIsEnabled) searchFrameObject.tableWidget.setItem(row,column+4,item) When i search in DB, i print result.name or print result.stock , everything is OK. But when i import them into QtableWidget i see just node result.name addeed to widgets. (all of nodes filled from result.name) My Question is , How i fill rows and columns with my fields?

Re: Installing resource data files and finding them

I've used an ugly hack to work around this problem: * Patch the ‘MANIFEST.in’ and ‘setup.py’ to omit all mention of the resource files. This makes the Python Distutils simply omit the resource files and not install them at all. * Add a series of rules to the package builder to explicitly install the resource files to a temporary build location. Make sure these rules work for the multiple binary packages and for multiple builds. * Install the resource files for each package to an FHS-compliant location outside the Python package. * Make a symlink within each installed package to the resource location for the package. That works for now. It's ugly and a maintenance burden, though: I would hate to need to do this for resource files in every Python package. > I had hoped to use Python's standard library (Distutils?

Ideally I wouldn't need to subvert Distutils, but could somehow tell it what I need and have it record the install-time decisions for the run-time application's needs. I'm still hoping there is a standard-library way to do this.

Once you start distrusting to that level, you become paranoid to a point that's inappropriate to all but the most critical situations. I'd accept and maybe even recommend that sort of paranoia if you're running a nuclear power station, or an automated weapon system capable of firing missiles that destroy the planet, or a bank that holds everyone's money. For the average Joe, there's no point panicking. Also: That hack works beautifully when there's precisely one C compiler. In today's world, there are many (well known ones like gcc, clang, MS Visual Studio (whatever the compiler from that is called), and a bunch of lesser-known ones as well), and it's pretty easy to just grab a different compiler and build. The chances that your code will be falsely compiled by TWO compilers would have to be infinitesimal, and you needn't stop at two. Since many people build (to take one example) gcc from source, using an old version of gcc, the hack would have to be propagated to all current gcc builds in some way - you can't simply build once and install the binary as the official C compiler, not in today's distributed society. (If you're truly paranoid, you might believe that gcc has had the hack in it since its inception. But some people build gcc using other compilers, too.) If you can't trust any code you didn't write yourself, you're left with Rene Descartes' line "I think, therefore I am" - it's impossible to prove anything else, since you can't trust your senses. So go ahead! Distrust everything and use nothing. Or accept that, even if you're the target of a huge conspiracy, it doesn't even matter, because life still goes on :) ChrisA -- https://mail.python.org/mailman/listinfo/python-list

"Recent" revelations? Where have you been for the last, oh, 20 odd years? Remember when people who talked about Carnivore and Echelon were considered in tin-foil hat territory? I do. I think it was Paul Krugman who talks about the one thing worse than being wrong is being right too soon. In context, he's referring to the Bush administration's adventures in Iraq, and how those who were right a decade ago are still routinely ignored even after being proven right, while the Very Serious People who were utterly, obviously wrong are still feted as experts. The same applies to the surveillance society. This didn't just appear overnight. You don't build programmes the size and complexity of PRISM, Tempora, Stellawind, X-Keyscore, Dropmire, and no doubt others that we still don't know about, overnight. When it comes to NSA spying, before Edward Snowden, there were these other guys: http://www.usatoday.com/story/news/politics/2013/06/16/snowden-whistleblower-nsa-officials-roundtable/2428809/ And if you think it's just the NSA, you *really* haven't been paying attention.
