Hey there! when I add the scroll bar using this method to my project, I put all my stuff into the Second Frame as you said, but it was left aligned and when I used another screen that was bigger than 1080p, I noticed the misalignment difference. Also instead of scrolling down, this scrollbar for some reason scrolls up when I try to scroll down. Definitely its something that I am doing wrong, but can't figure out what.

[@Patricutza20]

I have a situation that is quite specific, and I am trying to find a solution for it. My window is not scrollable straight away, but rather it is meant to get so during the execution of the application, as more widgets are added to the scrollable frame. When the application opens with too few widgets for it to be scrollable, the scrollbar appears inactive, but if I click the up arrow, it does go up to a blank part of the window. As the frame gets populated with widgets, the scrollbar does not get activated, and the down arrow remains inactive, thereby rendering an only upwards scrollable window, where "up" is blank. The same situation occurs if, in the buttons example you have provided, for example only 3 buttons are instantiated. If you have any idea for how to fix this please let me know, as I fail to comprehend how exactly to google this situation.

[@pranav-kale]

is your canvas in separate window or the main frame appears in a window with other widgets that are placed using grid system? I had the same issue so i transferred the whole scroll situation onto a new separate window. Still i have to resize the window once so that the scroll becomes active . will update if i find any other solutions.... ;)

[@frozenmolasses5932]

[@DeeceTube]

It works, and I get the parts. Yet, there's something I don't quite understand about this. I couldn't implement it in sort of a free form way, I had to follow pretty close. I guess there's a chance I just tripped on something syntactic somewhere, or something like that. You're right, though, it's a little bit convoluted. I get a lot of none types, which I think means I'm not passing things quite correctly. Arguments and events have to be in order in terms of how the functions are defined in tkinter - I don't exactly want to learn all of python, but I appreciate that those things are generally accessible when I need them.

[@paolosestini850]

Thanks for the exhaustive explanation. I noticed, though, that if you resize (shrink) the window horizontally the scrollbar disappears. Any idea on how to avoid this? Thanks.

[@ThankYouESM]

The next step for this is to make it work with zooming images and especially have the scrollbars vanish if the image fits well enough on the screen (which avoids flickering).

[@rastkogojgic699]

You are the best teacher John! I recently bought your entire Codemy course, and I'm loving it. I have a question though, and I haven't been able to find an answer anywhere. I have managed to add a scrollbar to my app. However since a new scrollable background is a frame, that means all labels and text will have an ugly gray outline around them. I can't change that, as I'm using an image as a background. On the other hand, Canvas allows us to use images as background. Is there a way to make Canvas itself scrollable? And if so, how to make the background image stretch downwards? I hope that my question is clear. Thanks!!

Hello John, Thank you so much for the video. It was very very helpful. However, I have a quick question if you don't mind taking some time to answer it. So after adding the second frame to the window in the canvas and executing the code, you get the result what you have shown. I currently have multiple treeview widgets bound to root window frames which stretch in the horizontal direction upon maximizing the root window to fill the screen. However, when I try adding canvas the way you did and binding these treeview widgets to the second frame, these widgets do not expand anymore when I maximize the root window. Could you please help me on this issue?

I have another question that to maximize the window I am using window = Tk() window.state('zoomed') But issue is the scroll bar. When the window opens there is no scroll bar but when I click the maximize button in top right corner then the scroll bar appears and also works fine. I think there would be the issue of focus. I need to give focus to the scroll bar but I don't know how can give it. If I remove the zoomed state then scroll bar also works fine but I need to maximize it to full screen with top and task bar present. That is why I am using state zoom. Please help me in this regard.

Hello Sir, I tried this code and it worked. However, when I apply it to the code I have written few days ago, I wasn't able to get it to work. My code has some frames in it and those frames have some labels and images. So I changed placed the frames into the second frame. Doing this however does not work Does using place instead of pack and grid for the frames I have affect the result. Just some additional information, I use place because I find relx, rely, relwidth, and relheight very useful in layouting a program. Any help will be appreciated

t tave app that will show data from API url calls. The app is 2 side by side frames. Left frame is details to run the api calls and the right frame (output frame) has the canvas displayed.

I'm trying to add the scroll bar for my frame which only has labels. For the labels, I've used the .place method to align them in the frame, but for some reason this causes them to not show up when adding the scroll bar. I double checked and can confirm they show up when I place them in the frame with the .grid method but I'd rather use .place as it lets me better align labels of different length - Any reason why I'm having issues with .place here?

[@Codemycom]

place specifies and very specific PLACE to put your widgets. Scrollbars move everything around..so using place with scrollbars is not advised. You'd have to manually resize the frame etc, and it's a huge hassle
