## Summary
This MR adds a config dialog for the Clipboard plugin, where the user can toggle
whether to share password and/or anything else with other devices.
Implements !39
BUG: 458063
According to previous discussion at !39 (and the bug linked), some users want to
skip sending passwords to other devices while others rely on the existing behavior.
This MR addresses that by allowing users to control those two types separately and
will replace !39 if merged.
Borrowing the idea from !39, the `x-kde-passwordManagerHint` MIME data hint is used
to determine whether the content is considered secret. I've tested this method with
KeepassXC which [sets this correctly](a6d3f973fa/src/gui/Clipboard.cpp (L62)). See test plan below.
In theory, MIME also can be used to test for images and another checkbox can
be easily added should we decided to support images later. For now though, the
enum and the config supports only passwords or "anything else". Both defaults to true,
thus keeping full backwards compatibility. I've been keeping both unchecked since
I only share in one direction (Android to Linux), which wasn't possible until this MR.
Others may want to make their own choices.
## Test Plan
Please reference the screenshot above for the steps.
From the indicator, right-click and select `Configure`. Select a device from the
left side (or pair one if needed). In "available plugins", make sure "Clipboard"
is checked, and verify that a "Configure" icon button is now shown on the right.
Clicking that icon should bring up the new config dialog, where the two check boxes
can be toggled as desired. Click on "OK" to save and apply the settings. Clicking on
"Defaults" should bring both back to checked (the default behavior).
Copy normal plain text from your favorite text editor and it should be sent to another
device if the "anything else" checkbox is checked. I've tested this on an Android phone
but I see no reason it won't work elsewhere given the code for sending has not been changed.
(Feel free to test on other devices.)
Open KeepassXC and select an entry, right click and select "Copy password". This sets
the MIME hint so it should be treated as a password, controlled by the "passwords" checkbox.
I've toggled the settings multiple times on and off. Once "OK" is clicked, the next clipboard
change should pick up the latest settings.
I've only tested on Linux desktops (Arch Linux) since I do not own a Mac. I don't believe any
OS X application sets `x-kde-passwordManagerHint` at all, so they may be controlled by "anything else".
Copies over David's implementation in Klipper and integrates it in the
plugin. To do so it splits the ClipboardListener class into 2
subclasses: one that uses QClipboard and the other that uses the
DataControl classes.
BUG: 359747
Summary: Added a timestamp to track clipboard changes, so when a new device connects it will sync the most recently updated clipboard to both devices.
