Python Button Command Parameter

Spechal — Wed, 02 Dec 2009 10:05:15 +0000

Here is a crude example of how to pass a parameter to the command of your Tkinter Button.

import Tkinter

def command(text):
    ButtonText.set(text)

root = Tkinter.Tk()

ButtonText = Tkinter.StringVar()
ButtonText.set("Do Callback")
Tkinter.Button(root, textvariable=ButtonText, command=lambda x="Hello World!": command(x)).pack()

root.mainloop()

Python MySQL Associative Array

Spechal — Fri, 27 Nov 2009 23:26:04 +0000

By default, the MySQLdb module to access a MySQL database returns the data as an integer indexed array. Sometimes this is not desirable and an associative array is preferred, such as the mysql_fetch_assoc function in PHP. In addition, we will be using the pprint module which is similar PHP’s print_r

Here is the Python equivalent:

import MySQLdb
import pprint
# connect to the database here
db = MySQLdb.connect(...)
c = db.cursor(cursorclass=MySQLdb.cursors.DictCursor)
query = "SELECT `name`, `address` FROM `table`"
c.execute(query)
rows = c.fetchall()
c.close()
pprint.pprint(rows) # i.e. print_r($rows)

Hope that helps someone.

Python emulate mouse click in Windows

Spechal — Fri, 20 Nov 2009 14:38:18 +0000

The following bit of code, which requires the win32api, simulates a mouse click using Python under the Windows OS.

import win32api, win32con

def click(x,y):
    win32api.SetCursorPos((x,y))
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN, x, y, 0, 0)
    win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP, x, y, 0, 0)

click(100, 100) # simulate mouse click at 100px, 100px

Python Print Screen and Save Image in Windows

Spechal — Fri, 20 Nov 2009 00:07:14 +0000

So you need to do a “Print Screen” and save the image in the clipboard huh? I had that exact need too. Let me save you a few hours of trouble and tell you that the win32clipboard does not yet have the ability to return the contents of the clipboard when the contents are BITMAP, despite the CF_BITMAP constant.

How do you do it then? I was wondering the same thing. Behold, PIL. PIL, the Python Image Library, saved me from a massive headache.

Here is the code to take a screen shot and save it. You will need the win32api and PIL libraries.

import win32api, win32con, ImageGrab
win32api.keybd_event(win32con.VK_SNAPSHOT, 1)
im = ImageGrab.grabclipboard()
im.save("screenshot.jpg", "JPEG")

Now wasn’t that easy!
