Show Signature Help
Shows parameter help for the call being typed at the editor caret.
Read this while writing a call and you need the parameter list and order of the routine: it shows signature help at the caret, bound to Ctrl+Alt+S.
Where to click
- RAD Studio main menu: drag-lint > Show Signature Help
Details
Shows parameter help for the call being typed at the editor caret. Reach for it to check a routine's parameter list and order while writing a call.
Reaching it in the IDE
drag-lint > Show Signature Help
Keyboard shortcut: Ctrl+Alt+S.
Running it from the CLI
There is no standalone CLI verb for this (feature map CliVerb:
"(none - in-process)"). It is served in-process by the IDE plugin. The
bundled language server exposes signature help over stdio to other editors
-- the Features page lists signature help among the methods
drag-lint lsp implements -- but that is a stdio protocol server, not a
one-shot CLI command.
What it needs
The feature map marks this row's Index column "n/a" and its Mechanism "in-process". It needs an open editor with the caret inside a call's argument list.
Example
Illustrative: position the caret inside the parentheses of a call to
TCustomerOrder.Create(...) and press Ctrl+Alt+S to show that
constructor's parameter help.
