python - Prevent Label to be re-aligned after askdirectory() is closed -


i built window display labels, entry field , button. button opens tkinter.filedialog.askdirectory(). after choose directory , close dialog label updated along text entry choice.

the problem after happens description of text entry (another label on left) realigned in cell. don't know why happens, there behind-the-scenes behaviour i'm not aware of?

here's sample code use.

from tkinter import * tkinter import filedialog tkinter import ttk   def folderdiag():     scanfolder.set(filedialog.askdirectory())  c = (n, w, s, e) scanfolder = stringvar()  root = tk() root.title("testing") root.columnconfigure(0, weight=1) root.rowconfigure(0, weight=1)  frame = ttk.frame(root, padding="3") frame.grid(column=0, row=0, sticky=c) frame.columnconfigure(0, weight=1) frame.columnconfigure(1, weight=1) frame.columnconfigure(2, weight=1) frame.rowconfigure(0, weight=1) frame.rowconfigure(1, weight=1) frame.rowconfigure(2, weight=1) ttk.label(frame, text="welcome!",           font="tkdefaultfont 24 bold").grid(column=0, row=0, columnspan=4,                                              sticky=c) # label centered after dialog closed ttk.label(frame, text="select folder scan:").grid(column=0, row=1, sticky=e) ttk.label(frame, textvariable=scanfolder).grid(column=2, row=2)  scan_folder_entry = ttk.entry(frame, textvariable=scanfolder).grid(column=3,                                                                    row=1) browse_button = ttk.button(frame, text="browse...",                            command=folderdiag).grid(column=4, row=1)  root.mainloop() exit(1)

if understand correctly, need this:

|    0    |         1         |      2     |  # column number |                welcome!                  | | select  |       entry       |   button   | | label                               |

so:

from tkinter import * tkinter import filedialog tkinter import ttk  def folderdiag():     scanfolder.set(filedialog.askdirectory())  root = tk()  c = (n, w, s, e) scanfolder = stringvar()  root.title("testing") root.columnconfigure(0, weight=1) root.rowconfigure(0, weight=1)  frame = ttk.frame(root, padding="3") frame.grid(column=0, row=0, sticky=c) frame.columnconfigure(0, weight=0) frame.columnconfigure(1, weight=1) frame.columnconfigure(2, weight=0) frame.rowconfigure(0, weight=1) frame.rowconfigure(1, weight=1) frame.rowconfigure(2, weight=1) ttk.label(frame, text="welcome!",           font="tkdefaultfont 24 bold").grid(column=0, row=0, columnspan=3,                                              sticky=c) ttk.label(frame, text="select folder scan:").grid(column=0, row=1, sticky=e) ttk.label(frame, textvariable=scanfolder, justify=left).grid(column=0, columnspan=3, row=2, sticky=w)  scan_folder_entry = ttk.entry(frame, textvariable=scanfolder) scan_folder_entry.grid(column=1, row=1, sticky=ew) browse_button = ttk.button(frame, text="browse...",                            command=folderdiag) browse_button.grid(column=2, row=1)  root.mainloop()

your code create layout:

|   0    | 1 |    2    |    3   |    4   | | welcome                       |  ---   | | select | - |   ---   | entry  | button | |   ---  | - |  label  |   ---  |   ---  |

enter image description here

for reason leave #1 empty. width = const = 0. forget it.
select doesn't attached entry. columns #1 , #2 separate them. select attached right edge of #0 column.
when update label increase width of #2 column => increase space between #0 (select) , #3 (entry). select stay attached right edge of #0.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
