TopLevel | A New Way to Javascript Your HTML

I've had a lot of issues with this application because I am simply not good enough yet, but I am almost done with it and just want to finish it so I can move on to some slightly lower level projects.

It is a tkinter to-do application.

You can add a Task to a listbox

For every Task, there are some associated attributes, among others: ````self.value = vandself.connectivity = c. The hierarchy of the tasks displayed in the listbox is determined by the value of val_var``` (e.g. the higher the value the higher on the list it will be displayed).

The Task and the associated attributes are determined by the user's input when one creates another task.

The Task is appended to a list task_list and after the user has added more than 1 task to the list, the next time one adds a task one will have the option to check existing tasks that it is connected with somehow.

The list is sorted so the task with the highest value (val_var) is displayed at the top of the Listbox and the task with the lowest value is displayed at the bottom of the Listbox. You can "Save tasks" and then launch the application at a later time where you can then "Load tasks".

Issue 1:

After loading tasks from a saved .dat file, it displays in the Listbox in the order it was saved in. However, if you now want to add another task at least two undesirable things happen:

1. The tasks now loaded into the Listbox are now not displayed as checkbuttons upon adding a new task.
2. When you add another task (again this is after loading the .dat file) the Listbox will delete what was just loaded and the Listbox will only display the newly added task.

I am somehow interested in being able to load the Tasks instances from the .dat file and then append them to the task_list so they are a part of the current session/instance of the application, but I don't know how one might do that.

Issue 2:

On a given session where tasks have been added to the Listbox, they can be deleted from the listbox using the "Delete task" button. The selected task in the Listbox is deleted, but it is not the same task that is deleted from the task_list.

To test what I mean by this one can add a couple of tasks to the Listbox and then delete one after doing so. Notice upon trying to create yet another new task that the one just deleted from the Listbox will still be shown as a checkbutton - however, another task that wasn't just deleted has now vanished as a checkbutton.

Any help with these issues will be sincerely appreciated.

Here's the code:

I have seen some code in swift some thing like below. It used in a Framework, I'm trying to replicate the same code, as we knows getting errors. But how it is used in Framework?.

If we see the below code Strings, Localized and String code its not implementing init or extension of String replace(::) not implemented. What this code means and how to use in project as TopLevel Objects?

I can able to access this code by importing Framework, and I can make changes to that code.

Here is the code.

The idea is that the scrollable canvas and its text widgets grow or fill the entire root/toplevel when I resize it.

I can do this if I work on Frames but for a scrollable frame you need to create a canvas widget and make it scrollable. Now I don't know if the problem is the canvas or the inserted widgets on the canvas?

M trying to create a desktop app but facing some problem while switching between frames using button. Its working all fine but it gives me an extra blank window(consist nothing) when I run my project. Below is my code. Please suggest me any changes or error in my code.

I wanted to login to a webpage three times as follows.

1. Push the "button1"
2. Login window pops up then enter ID & PW and push the "Enter" button
3. do something
4. repeat #2 & 3 three times.

I am stuck at making the code wait until a user pushes the "Enter" button.

I'm pretty new to python. Any comments will be greatly helpful.

I came across an issue. I know that we can create a new window using Toplevel(). I want to make the new window exactly like my original window. Here is a small piece of code. How can I make the Toplevel look and function like my main window?

I am creating a templates application where users can write any HTML/CSS code inside a textarea (E.G. a full html page pasted on a textarea). These users are mostly familiar with html and css so we have not yet implemented markdown. One important feature that we would like to add is the ability to preview the html in the textarea before submition. I have thought of ways that these can be done, but I am not sure which would be correct and most maintainable.

• Preview the html inside a div in the same page - the problem I can see here is the existing CSS style might interfere with the CSS styles the user typed in the textarea. Furthermore, if the user writes body tag in the textarea, there will be another body tag inside the existing body tag of the actual page, so the html might become malformed.
• Preview the html on a separate window - the problem is I do not have much control on this (if the user uses a poppup blocker, for example)
• Preview the html on a separate tab - the problem is the user might be confused (E.G. closes the whole browser, thinking that it opens in a new window)
• Preview the html on an iframe - this is doable, but will require me to create an additional .html file just for previewing
• Preview the html on a modal - this is doable, but I am not sure if modal bodies will accept toplevel tags like title or body

Can anyone help me? Which of these potential solutions are best? Or is there a better solution?

In a toplevel (unix, GNU) Makefile I want to iterate over a list of subdirs and execute tasks in there but exclude some of them. In this case exclude all subdirs starting with an underscore (_)

The following is working in iterating but ignores the exclusion regex. It still visits dir "_exclude".

In particular I think it ignores the "start of string" ^ (or it takes it literally). I have tried other regexes and they do work. Any idea how to fix that? Or indeed if you have any idea how to eliminate the shelling out or not using GNU makefile extensions?

I am trying to call a new window by pushing the button of an existing window. The original window should close when the new window is being created. When I push the button the new window will show up as expected but additionally a blank window will appear. Using tk.Tk() or tk.Toplevel() will lead to the same result.

Later in the program I want to destroy the created window again. When using tk.Tk() closing the blank window by mouse will create an error "application has been destroyed" when the destroy() method gets applicated to the new window.
