Restore RichTextStyle with Undo/Redo in Compose Desktop

[MohamedRejeb]

• Now if we use undo/redo in compose desktop the restored text doesn't have the right style

Hi, can you add functions to RichEditState for Undo/Redo?

[MohamedRejeb]

It's on the scope, I'll try to add it before 1.0.0

Hi @MohamedRejeb is the undo functionality added now?

[MohamedRejeb]

Hi, not yet, but it's on top of my list.

[kannansrepo]

Thanks! sorry to bug you, Is there any work around for this until you introduce it? do you have anything in your mind, I can work on it.

These should be the steps needed to implement this feature.

• Two stacks for undo and redo.
• Two public methods undo() and redo() in RichTextState class.
• When the state is changed, we need to add the old state to the undo stack (This is challenging because we need to ignore some changes, such as selection changes...).
• Add key event listener and call undo and redo methods when command z and command shift z are pressed.

The upcoming BasicTextField2 already has support for it: https://android-review.googlesource.com/c/platform/frameworks/support/+/2748196

For now it seems to be Android only but eventually this comes to the multiplatform implementation as well and/or you can copy the implementation.
