Introducing an improved IP Address and Port input control in ProxySettings component

[pablomartin4btc]

Adding a new improved ValueInput control to handle both IP address and port values combined in the same field (as it was designed for QML, current QT project have them separately) with the correct visual formatting (255.255.255.255:65535).

In order to add/ change the IP address and port value, user needs to enable the fields (currently in main branch this doesn't work and this PR fixes it). Currently the IP address and port input fields don't allow more than 5 digits and this PR also correct it so the user can enter a complete IP address and port value.

If an invalid IP address (e.g. 127.0.:9050) and/ or port (e.g. 127.0.0.1:) are entered an error message will be shown as we do in other fields.

Implementation details:

In this iteration, validation for this control is implemented using both a function within the control itself focused solely on ensuring correct formatting and a simple regex validator for the valid input characters. Future versions will see integration with network model classes, enabling parsing of IP addresses and ports and additional checks, such as those outlined in doc/p2p-bad-ports.md.

Note:

Persistence/ wiring of the settings and creating the proper network connection thru the Proxy will be performed in a different PR, the idea is to isolate UI experience/ testing in case we need to make changes on that aspect separately and we concentrate on the functionality behind later.

Just tested on Android mobile. This is a nice update.

I don't think the input field needs to turn orange when it goes from disabled to enabled state (by toggling the line above).

Also interesting how the "Enable" title briefly turns orange when tapping. Feels a bit surprising and unnecessary. I think the title could just remain white.

The copy for the Tor proxy is too confusing still.

Enable to run Tor connections through a dedicated proxy.

When disabled, Tor connections will use the default proxy (if enabled).

Can we remove that second line?

I've incorrectly used a different State in the code of the input control (ACTIVE), I've fixed it with the correct one now (FILLED).

The new IPAddressValueInput control follows now the same pattern as the ValueInput control ("Block Storage Limit (GB)") in the "Storage Settings" page.


Can we remove that second line?

Yes, that wasn't touched by this PR, but corrected it as requested.

• Updates: I've addressed feedback from @johnny9, @GBKS and @D33r-Gee. Thanks for your valuable reviews!

[pablomartin4btc]

Noticed some missing pieces and a bug in initial state. I left comments and suggested changes. Wrong actionItem type was used and showErrorText needed to be connected to the loadedItem.validInput property that you added.

It seems I did something wrong when I updated the 1st commit. I'll correct it in a bit with your validInput initialisation value suggestion.

• Updates: I've solved the issue reported by @johnny9.

• errorText is displayed at both, while only one is invalid

Sorry, you've found another bug in the code, the Tor IP input points to the Default Proxy one. I'll fix it immediately.

• it's unintuitive imo that the errorText shows up only after enabling/disabling and/or closing the dialog or window

The errorText will be shown only onEditingFinished (another way could be onTextChanged, but it's too intrusive I think as the user perhaps didn't finish to enter the value and already sees the error message), but it's a good point that even the IP is invalid we should not display the error if we disable the input field. Is that your point? (edited:) If so, should we go back to the default value 127.0.0.1:9050 or leave it there even invalid (please check latest update 6b2621ee7457051a655b4add76f4e35cdf3c9279)?

I understand your point, but for me I'd prefer that behavior. The few users who use this and enter it will only enter it rarely. (in contrast to maybe regularly manually typing in a BTC address, then yes such behavior might be annoying.) Because now I enter it, make a typo and navigate back. There was no indication for me that I made a mistake, until I navigate back to the dialog.

is invalid we should not display the error if we disable the input field. Is that your point?

no, the above was. no strong feelings about this one, both are ok imo

If so, should we go back to the default value 127.0.0.1:9050 or leave it there even invalid

yes I'd say to leave it, as user intent was to enter something else

Ok, let me update that. It would be also good to see others reviewers takes on this.

Thanks, I'll investigate what's going on.

[pablomartin4btc]

• Updates: I've addressed latest @MarnixCroes's feedback.
  • Fixed the reported issue on new IPAddressValueInput field being glitchy when hovering;
  • Moved validation logic from the onEditingFinished event into onTextChanged one, as requested according to the specified use case.

Tested on macOS M1, very nice!

One thing I would change:

Tor connections can also be run through a seperate Tor proxy

I feel like this is redundant here a bit, and Tor proxy description says it all
