Add a tag to stop user from editing anything.

[littlewhitecloud]

I was testing the widget and I found we can edit the output and the path.
Then the widget became what a mess.
I through a simple solution to fix it:

• Create a uneditable tag.
• Add it to the path output and command output.

[Moosems]

I had fixed that with the left right up commands...

[littlewhitecloud]

？

[littlewhitecloud]

But I can still delete things.

[littlewhitecloud]

[Moosems]

There's nothing gone.....

[littlewhitecloud]

6,

[littlewhitecloud]

Actally, the left right up commands has problem, If I choose the text and press delete, it will still delete.

[Moosems]

So clicking needs a bind.

[littlewhitecloud]

Is there a way to give a readonly tag?

[littlewhitecloud]

So clicking needs a bind.

I prefer use a tag to set the text above it read only.

[Moosems]

There's no built in way but I can create one.

WOW! How?

[Moosems]

Bind all keypresses and button clicks and determine if the end result would be on top of any of the tag ranges. If it is, cancel the action otherwise allow it. Up and down get special treatment.

Good idea, but bind a lot maybe make the program slow.

[Moosems]

It'll be fast enough :).

@littlewhitecloud I'm going to do a ton of work tomorrow on the repo (eastern time US) so buckle up :D.

So I think We should split it out from the improve pr, create a new one and starting our trip :)

from tkinter import Tk, Text, Event

root = Tk()
txt = Text(root)
txt.pack()

txt.tag_configure("important")

txt.insert("1.0", "Hello, World!")
txt.tag_add("important", "1.0", "1.5")

    # Things to check:
    # Is the text that would be gone to by typing on the same line and to the right of anything important?
    # Are we selecting stuff? In most terminals, that shouldn't even be allowed.
    # If it's a click event, is the clicked char important?
    # If any of these fail, we should return "break"
    widget = event.widget
    if widget.tag_ranges("sel"):
        widget.tag_remove("sel", "1.0", "end")
    # Determine the action (click or keypress)
    # Keypress check for a few things: is it backspace (check if previous character is a special one, up or down which inserts that line, return creates a new line and runs the code, and all modified ones like control/command-a and blocks those)
    # Clicks check for the index of the click and if it is inside one of the special we just bring it to the start of the non special chars

    important_ranges: list[tuple[str]] = widget.tag_ranges("important")

@littlewhitecloud, I am still working on this from my phone but here's an update.

[littlewhitecloud]

# Edit it on iPad, maybe have a lot of typo
self.cursor = 0
self.text.bind(“Left”, self._left)
self.text.bind(“Right”, self._right)
self.text.bind(“Click”, self._click)
# maybe merge them into one function
def _left(self, event):
    self.cursor -= 1
    if self.cursor < 0:
       self.text[“state”] = “readonly”

def _right(self, event):
    self.index += 1
    if self.index > 0:
        self.text[“state”] = “normal”

def _click(self, event):
    self.index = #cursor index
    if self.index < 0 and self.text[“state”] == “normal”:
         self.text[“state”] = “readonly”
    elif self.index > 0 and self.text[“state”] == “readonly”:
         self.text[“state”] = “normal”

[littlewhitecloud]

My form, but still have a lot of logic problem, fix it later.

[Moosems]

Clear also needs to be a special command for typing.

[littlewhitecloud]

find a new and better way to improve it.

    def updates(self, _: Event) -> None:
        """Update cursor"""
        self.cursor = self.text.index("insert")
        if float(self.cursor) < float(self.latest):
            self.text.bind("<KeyPress>", self.eat, True)
            self.text.bind("<KeyPress-BackSpace>", self.eat, True)
        elif float(self.cursor) >= float(self.latest):
            self.text.unbind("<Key>")
            self.text.unbind("<KeyPress-Backspace>")

    def eat(self, _: Event) -> str:
        """Just eat"""
        return "break"

Mine should be able to be put in a duct allowing for better handling. I'll need to finish the handler but I have a feeling it will work well.

How long will it take to finish it?

[littlewhitecloud]

If it still take a long time, maybe we should fix it in another pr. Just use mine version as a temp solution. When you are finished, we can remove mine can replace with your solution.

[Moosems]

Yeah. I'd merge the PR and when I have a free week I'll make a big update PR.
