clipboard viewer
clipboard viewer
This is a small (this time it is small, really) script that will show the content of the clipboard in an editable textbox.
How to add the textbox: add a custom view and set this script in the create event, the resumed event and the paused event (I used a trick to detect the created event that maybe will be broken in the future. If so tell me to fix it)
How to use the textbox: everything is shown in the video but here is the summary
When the textbox is resumed it takes the content of the clipboard, if it is text.
When the textbox is paused:
If the textbox didn’t changed, do nothing
If the textbox changed and the clipboard don’t, the content of the textbox is copied into the clipboard
If the content of the clipboard changed, even if the textbox changed too the clipboard keeps the text, and the textbox is discarded. This is done this way to be able to, for example, copy a part of the current clipboard easily.
It doesn’t use clipboard listeners. I know I can use them to update instantly the content, but in my opinion that’s not necessary in this case. This way the battery impact, if any, should be the minimum.
Note: you can change the color of the text in the first line of he script.

Just as a note: the presence of item is not unique for the create event. Touch event has that too…
Pierre Hébert I think there should be a better way to check for this situation.
