How to enable highlighting feature but still prevent text copy for LCP protected EPUBs?

[nareshsvn]

Hi

Currently, I am using the following code to enable the text select/highlight(annotations, highlighting) feature for LCP protected publication. But this code allows copying the publication.
Is there any way that, we can enable the text select/highlight(annotations, highlighting) feature without the text copying feature? Please suggest.

server.loadCustomResource("""
* {
user-select: auto !important;
-webkit-user-select: auto !important;
}
""".byteInputStream(), "fix-select.css", Injectable.Style) //#414

Thanks,
Naresh

You need to create a custom selectionActionModeCallback for EPUB, and create your own selection menu without the Copy option.

• kotlin-toolkit/test-app/src/main/java/org/readium/r2/testapp/reader/EpubReaderFragment.kt

  Lines 91 to 95 in adeb8f4

  	config = EpubNavigatorFragment.Configuration().apply {
  	// Register the HTML template for our custom [DecorationStyleAnnotationMark].
  	decorationTemplates[DecorationStyleAnnotationMark::class] = annotationMarkTemplate(activity)
  	selectionActionModeCallback = customSelectionActionModeCallback
  	}

• kotlin-toolkit/test-app/src/main/java/org/readium/r2/testapp/reader/BaseReaderFragment.kt

  Lines 166 to 190 in adeb8f4

  	val customSelectionActionModeCallback: ActionMode.Callback by lazy { SelectionActionModeCallback() }
  	private inner class SelectionActionModeCallback : BaseActionModeCallback() {
  	override fun onCreateActionMode(mode: ActionMode, menu: Menu): Boolean {
  	mode.menuInflater.inflate(R.menu.menu_action_mode, menu)
  	if (navigator is DecorableNavigator) {
  	menu.findItem(R.id.highlight).isVisible = true
  	menu.findItem(R.id.underline).isVisible = true
  	menu.findItem(R.id.note).isVisible = true
  	}
  	return true
  	}
  	override fun onActionItemClicked(mode: ActionMode, item: MenuItem): Boolean {
  	when (item.itemId) {
  	R.id.highlight -> showHighlightPopupWithStyle(Highlight.Style.HIGHLIGHT)
  	R.id.underline -> showHighlightPopupWithStyle(Highlight.Style.UNDERLINE)
  	R.id.note -> showAnnotationPopup()
  	else -> return false
  	}
  	mode.finish()
  	return true
  	}
  	}

However, this will not work when using a physical keyboard as the user can do Ctrl-C directly.

I didn't look further into addressing this issue, and maybe other edge cases. If you have some ideas feel free to share.

Thank you for your reply.

In the latest SDK I am able to use the text highlighting feature without a copy option.

1. In case the user wants to enable the copy feature along with the text highlighting feature in the latest SDK. is there a way to do it? Please suggest.

Thanks,
