Fix "Load PSBT" functionality when no wallet loaded by psancheti110 · Pull Request #399 · bitcoin-core/gui

psancheti110 · 2021-08-07T19:26:23Z

This PR provides a fix to the issue mentioned in #232.

Currently, the Load PSBT functionality works well in case a wallet is loaded but does nothing when a wallet isn't loaded.

If a function cannot work without a wallet being loaded, it is disabled by default (It is unclickable as shown in the image).

For e.g. One cannot Close Wallet or Backup Wallet or Sign Messages without a wallet being loaded. And hence they are disabled. But if you notice, Load PSBT options are not disabled by default even when a wallet isn't loaded.

As mentioned by hebasto in the issue description :

<hebasto> achow101: does "File" -> "Load PSBT from {file|clipboard}" make any sense when no wallet is loaded?
<achow101> hebasto: yes, for finalize and sending

This means Load PSBT should be working just as similar whether wallets are being loaded or not.

After making the required changes to the code, The Load PSBT works as expected even with no wallet loaded and the PSBT is finalized.

Approach ACK cb7b222.

I understand these indentations were suggested by clang-format-diff.py, but to keep verifying easy with diff --color-moved=dimmed-zebra, I'd suggest to keep the same indentations as they were in walletview.cpp.

Tested e5e0091.

I think the PSBTOperationsDialog::showTransactionStatus should be modified to correctly handle unsigned PSBTs:
