Control position of Tkinter common dialogs?
by python＠bdurham.com Dec. 9, 2016

Dec. 9, 2016

Python 2.7 under Windows: How can we control the position of Tkinter's common dialogs? Here's what we've discovered: * Certain common dialogs always open up relative to their parent window * Certain common dialogs always open up centered on the user's desktop * All common dialogs appear to ignore the optional parent= parameter Questions: * How can we force a dialog to open up relative to its parent window? * How can we force a dialog to open up centered on the user's desktop? Background: import tkColorChooser as colorchooser import tkFileDialog as filedialog import tkMessageBox as messagebox # always open up relative to parent windows fileOpen = filedialog.askopenfilename() fileOpens = filedialog.askopenfilenames() fileSaveAs = filedialog.asksaveasfilename() color = colorchooser.askcolor() # always open up centered on desktop folderOpen = filedialog.askdirectory() messagebox.askquestion() Malcolm

tkinter on android?
by Mark Lutz Sept. 26, 2014

Sept. 26, 2014

Has there been any work on porting tkinter to Android yet? The usual searches come up empty, but the following looks like a promising development in the Tcl/Tk front: http://www.androwish.org/index.html/home and there may be a few usable Python 2.X and 3.X Android ports to build on ("Python for Android" search results turn up SL4A, QPython, and others). This may or may not be feasible, but there are a lot of tkinter GUIs which would be great to have on an Android device; personally, I have tkinter-based text editors, clocks, email clients, calculators, and now calendars that see daily action elsewhere. Thanks, --Mark Lutz (http://learning-python.com, http://www.rmi.net/~lutz)

Can't find tkInter components to build tktreectrl

Greetings I am trying to build the extension tktreectrl-2.4.1 so I can call it from python. It took me awhile to sort out versions, but I think the version I want is under /anaconda ./configure --with-tk=/anaconda/pkgs/tk-8.5.13-1/lib --with-tcl=/anaconda/pkgs/tk-8.5.13-1/lib it finds tkConfig.sh and tclConfig.sh Michaels-MacBook-Pro:tktreectrl-2.4.1 mmuratet$ ./configure --with-tk=/anaconda/pkgs/tk-8.5.13-1/lib --with-tcl=/anaconda/pkgs/tk-8.5.13-1/lib checking for correct TEA configuration... ok (TEA 3.9) configure: configuring treectrl 2.4 checking for Tcl configuration... found /anaconda/pkgs/tk-8.5.13-1/lib/tclConfig.sh checking for existence of /anaconda/pkgs/tk-8.5.13-1/lib/tclConfig.sh... loading checking for Tk configuration... found /anaconda/pkgs/tk-8.5.13-1/lib/tkConfig.sh checking for existence of /anaconda/pkgs/tk-8.5.13-1/lib/tkConfig.sh... loading configure: --prefix defaulting to TCL_PREFIX /opt/anaconda1anaconda2anaconda3 configure: --exec-prefix defaulting to TCL_EXEC_PREFIX /opt/anaconda1anaconda2anaconda3 checking for a BSD-compatible install... /usr/bin/install -c checking for gcc... gcc checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... no checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ISO C89... none needed checking how to run the C preprocessor... gcc -E checking whether make sets $(MAKE)... yes checking for ranlib... ranlib checking for grep that handles long lines and -e... /usr/bin/grep checking for egrep... /usr/bin/grep -E checking for ANSI C header files... yes checking for sys/types.h... yes checking for sys/stat.h... yes checking for stdlib.h... yes checking for string.h... yes checking for memory.h... yes checking for strings.h... yes checking for inttypes.h... yes checking for stdint.h... yes checking for unistd.h... yes checking if the compiler understands -pipe... yes checking whether byte ordering is bigendian... no checking for sin... yes checking for main in -lieee... no checking for main in -linet... no checking net/errno.h usability... no checking net/errno.h presence... no checking for net/errno.h... no checking for connect... yes checking for gethostbyname... yes checking dirent.h... yes checking errno.h usability... yes checking errno.h presence... yes checking for errno.h... yes checking float.h usability... yes checking float.h presence... yes checking for float.h... yes checking values.h usability... no checking values.h presence... no checking for values.h... no checking limits.h usability... yes checking limits.h presence... yes checking for limits.h... yes checking for stdlib.h...

If tkConfig.sh and tclConfig.sh don't know where the headers are, where would you look for headers? There is no tkPort.h anywhere under /anaconda I've never seen configure generate include paths with a lot of hyphens. Is that coming from tkConf.sh or tclConf.sh? Thanks Mike

Cursor Index From Tkinter.Text in <KeyRelease> Gives Insconsistent Column, Test Case
by jevan＠freenet.de Sept. 13, 2014

Sept. 13, 2014

I want to get the cursor position (line and column) of the insertion point of a Tkinter.Text, but you may assume the answer is easy until you run this simple test run. Acutally I hope someone finds it easy. PROBLEM: My text editor project requires a custom undo/redo for Tkinter.Text. I put in the same string for both Test One and Test Two below, but undo does not act consistently due to a inconsistent column variable in KeyRelease event handler given by Tkinter. The problem seems to be that I type too fast for second test which produces a bad column value. Can you help me find the problem? TWO TEST PROCESS TO REPRODUCE THE ERROR: TEST ONE Type this string slowly: 'one two three' Press F1 to see each word undo. Result: Works fine. (For me atleast. Ephasis: type slowly.) TEST TWO Type the same string as fast as you can: 'one two three' Press F1 to see each word undo. Result: Gets the wrong column and does not undo properly. (Restart script and repeat this step if you don't see the error at first, it sometimes works fine with fast typing. I usually get it with 3 to 4 tries at the most.) QUESTION: Is this a bug in Tkinter, or am I not understanding something specific within Tkinter that would produce consistent columns for my undo/redo records? from Tkinter import * class TextView(Text): def __init__(self, root): Text.__init__(self, root) self.history = History(self) self.bind("<KeyRelease>", self.keyRelease) # used to capture a char at a time in keyRelease. If space char is pressed it , self.word) if __name__ == "__main__": root = Tk() root.geometry("400x200+0+0") textView = TextView(root) textView.pack() root.bind("<F1>", textView.undo) root.bind("<F2>", textView.redo) root.mainloop() --- Alle Postfächer an einem Ort.
