Dali 3D User Interface Engine

Copy and Paste (Selection)

Text can be selected by a long press or double tapping it. Depending on certain conditions a popup could be shown giving options including [CUT][COPY][PASTE], [SELECT ALL] or [CLIPBOARD]. Below these conditions will be explained.

[CUT] or [COPY] send the selected text to the clipboard ready to be pasted directly or via the clipboard UI. Pressing [PASTE] will paste the top item from the clipboard (what has just been copied, possibly from another application). If the system supports a clipboard UI this can be displayed by pressing the [CLIPBOARD] button.

Empty text means the user has not inputted any text, a text-control containing special characters or purely whitespace is not empty.

Below shows how the popup will look depending on the state of the text-control.
