Hi,
I have a Tkinter.Canvas of variable width. Is there a standard way of
asking the canvas which parts of it that is visible? I.e. on the
horizontal scale, I would like to know at what fraction from the left the
left visibility border is and from what fraction to the right the right
visibility border is.
Consider this ascii picture as an example

Hi,
In Tkinter, how to convert canvas coordinates to window
coordinates? To convert window coordinates to canvas coordinates
we are using "canvasx,canvasy". But how to do vice-versa? Iam

in window coordinate. How can i do it?
With Regards,

tab causes its corresponding panel to relocate to the top left position and
become visible and the other panels to become invisible, using CSS and
javascript. Each panel occupies most of an 800x600 screen.
While I am developing these screens in the visual designer, I give the top

Hello. When I tried to make Tkinter canvas widget respond to
MouseWheel event on Windows XP, I failed. The canvas just doesn't
receive MouseWheel event. I used bind_all to find out which widget
receives this event and the result showed that only the top Tk widget
gets it. This is really annoying. I wonder if this problem exists on
other platform. I googled, but found no appliable solution, so I wrote
one as following. It's not perfect,...

Hi there,
I´m using <canvas> dhtml tag for drawing some lines . The problem is that I generate them in a loop and then I want to draw, but nothing is happening... the coordinates of the canvas are (0,0) always?? or when a canvas is generated it gets global coordinates and so I have to try catch them another way?
Thanks for your time

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
