QUESTION
I'm building a small app where TextField text is updated or deleted via buttons on screen. I have utilised code from this post to be able to move the caret around and add text. I can add and delete characters within the TextField however when n amount of characters are added to the TextField then n amount are removed an IndexOutOfBoundsException occurs when you attempt to add another character as the caret position (when all characters are removed) becomes 1 when it should be 0. I do not know why it becomes 1 when it should be 0. What have I done wrong here?
ANSWER
Answered 2022-Mar-06 at 05:49Your code does not compile. You have a catch without a try. In the below code, I removed the [orphan] catch block. Also, your style sheet, i.e. file application.css, is not related to your problem so in order to make the code in your question a minimal, reproducible example I suggest that you remove that part. It is commented out in the below code.
I only get IndexOutOfBoundsException when caretPos is zero and I press deleteChar button. Hence you simply need to add code that handles that edge case. In the below code, refer to the part after the comment Handle delete when 'caretPos' is zero.

I have a FlowDocument like this:

Answered 2021-Jul-01 at 11:56The source of this problem is the RichTextBox Class. RichTextBox.CaretPosition takes a TextPointer and calls the Selection.SetCaretToPosition which has this definition: void SetCaretToPosition(ITextPointer caretPosition, LogicalDirection direction, bool allowStopAtLineEnd, bool allowStopNearSpace);
But in the RichTextBox Class it is hardcoded not to set near a space-char: Selection.SetCaretToPosition(value, value.LogicalDirection, true, false. see here
I mentioned MS to make properties in the RichTextBox Class so we can configure the last 2 arguments of Selection.SetCaretToPosition, when we need.
Solution: After a long road of "try&error", my best solution is, to replace the spaces with quotes. e.g. "".
On the one hand, this solves the problem with space-chars, on the other hand it is much more clear for the user, where to write.
Additionally I added some code to place the caret between the 2 quotes, when the user enters the Run with cursor keys or clicks the wrong place.
QUESTION
I have a div with contenteditable="true" and resize: both attributes which has centered text via flexbox
ANSWER
Answered 2021-Jun-11 at 13:28With JavaScript you can insert a space (' ') when you detect the contenteditable is empty. This pushes the caret position to the center.
