As the title says, I have got some PsiElement areas, and I want to prevent them from editing these areas(insert or move...)

Hi,
You can block the possibility of editing document ranges with
Document.createGuardedBlock().Karol Lewandowski
Thanks, it surely prevents from editing target regions. But once I edit the region, a dialog(title: GuardedBlockModificationAttempt) will come up and I hope it won't.
How can I make it disappear or customize the content of the dialog?
See
com.intellij.openapi.editor.impl.EditorActionManagerImpl#setReadonlyFragmentModificationHandler(Document, ReadonlyFragmentModificationHandler).I wonder how to override the default EditorActionManagerImpl...
You should not override it but call the method I pointed out, passing the edited document and your custom handler implementation that does nothing or displays custom information.
Thanks
By the way, I found guard block will automatically add a background color, how can I remove it..
It is intentional, and it's not possible to remove it. Users can change this color in the editor color scheme options.
Fine... But in my plugin, I'll add a background for all uneditable region. So I think I have to find another to prevent someone else from editing
