A Computer Person Journey
Hooray this is my first python post !
Here i want to share a tkinter based application on python 3 with login form. If user is logging in by clicked a login button then login form will disappear and main form will show up. This code is not connected to database yet ! Only playing with 2 toplevel tk window placement and control its state.
Donwload py source code below.
Tonight i just want to implement searching note by keyword, and its done. Download source code below.
May be this will be the final update for the application.
Execute it using wish not tclsh …
The notes application now is more sophisticated : can add note and browse note by note id. Search by keyword still a to do task but its give a lot of experience coding in tcl/tk.
Download source code here
Warning still in progress and still learning how to code tcl/tk.
Extract and execute using wish notes_sqlite3.tcl
Hello world using tcl/tk presented below may be more clear than oneliner before.
Here is the result.
Done.
Creating classic hello world program using GUI in Tcl/Tk can be done in few lines or may be only a line !
Oneliner can do below.
pack [button .b1 -text “Hello World” -command exit -width 50]
This line can be read : pack a button named .b1 with hello world text and exit command when clicked.
Save it to hello_oneline.tcl then run on command prompt : wish hello_oneline.tcl.
Voila!
Click the button and the window will close.
Bye ..
To bring tcl/tk programming language and some database connectivity for tcl on OpenBSD do command below as root :
pkg_add tcl tk sqlite3-tcl pgtcl
OpenBSD 6.6 can install tcl/tk 8.5 and 8.6.
Two extra package named sqlite3-tcl and pgtcl will give tcl capability to work with sqlite3 database and postgresql database.
Tdbc also a good choice for database connectivity. Tdbc packages on OpenBSD available for mysql, postgres, sqlite3. To add tdbc , we can do pkg_add tdbc-postgres tdbc-mysql tdbc-sqlite3.
Later will write more about tcl/tk.
