I have a MultiBoxList from TkinterTreeCtrl in a window with multiple columns, some are numeric, some alphabetical (I believe as far as this cares, they're all alphanumeric). This has been populated from a database.

I would like to be able to click the column headers to either: switch which column is being used to sort the list, or: reverse the sort order (i.e. descending ascending) if that column is already being used to sort.

Below is an outline of one of these lists.

I created an tkinter based app for users can make entries and modifying them if needed. This app interacts with SQLite for data storing purpose. However, I have an issue of deleting multiple data entries in SQL database via tkinter. You can check the code below:

How can I select multiple rows in a treeview where in the treeview is pulling up data from MySQL database, so that I can display them in my text box. I am able to do this for one row at a time but not sure on how to select multiple entries. I basically have 2 frames in my GUI, left and right frames. Left frame shows a treeview with the animal names and right frame shows a text box. When someone selects the animal name and hit Add button, it should be added into the right text box. Just want to figure out on how to do this for multiple selections. Below is my code so far.

I am having trouble getting tkinter.Canvas to stay within the bounds of its row and column in the grid manager.

This is how it looks to begin with

As required, the scrollbars appear when the window is shrunk enough that the text won't all fit

When the scrollbars are used, it becomes evident that the canvas is still behind the scrollbars

I need to figure out how to adjust the canvas so that it stays within row 0, column 0 of the grid manager and doesn't spill over to row 1 and column 1 or further. The following is the main code that has the problem in it.

I need help on how to open html file based on selected filename in my dropdown menu.

My problem :

when I run my code, it shows the interface like in image.

when I clicked "show data", it go directly to the other browse. it doesn't show my html file as attached image.

I just want, when I select a html file in dropdown list then click "Show Data", it will go and open my html file.

Thanks IN ADVANCE

Here is my code :

I am using Tkinter for building an app and i need scrollable windows. I created a scrollable container using Canvas: ScrollContainer . After this I incorporated the main logic of my program into this container where I put a button that opens another separate TopLevel window. This separate window also has to be scrollable . Therefore i also include it in the same container class

Now, the problem: When I run the program my main window scrolls fine. I open the TopLevel window after clicking the button. Secondary window scrolls fine. After I close the secondary window and hover the mouse again over the main window, now it doesn't scroll and i get an error in the console:

So I want to have a vertical and horizontal scroll bar on the window that automatically updates for the size of the canvas. I got it partly there, and right now the code creates extra scroll bars for each update and the horizontal scroll bar doesn't span the length of the whole canvas. Here is a sample I created to illustrate this:

I'm using the code below to create two scrollbars in a tkinter window, after that I fill it with text widgets, etc.

The vertical scrollbar looks ok, and seems to be working ok (except that I can't use a mouse-wheel to scroll with it), but the horizontal scrollbar appears to be squashed into the bottom, right-hand corner of the window.

As far as I can tell, I'm setting both scrollbars up the same way, so why would the horizontal one not extend right across the bottom of the window?

I have three MultiListbox items and two entries. When I will double click on the MultiListbox item then MultiListbox selected row information will come to the entries. For this reason, I'm trying to add a function in my MultiListbox Class and called this function in another Class but I don't know how can I do this. Heare is My code:
