Code reference information
In DataGrip, you can see where and how symbols, such as variables, arguments, or functions are defined in your project. For this purpose, the IDE features the Quick Definition popup.
To view definition of a symbol, select it in the editor and press Ctrl+Shift+I (or click).
Alternatively, with the Ctrl key pressed, hover the cursor over any symbol. DataGrip displays the symbol as a link and shows its definition in a tooltip. Click this link to jump to the definition of the symbol.
Click the icon in the top-right corner to open the definition in the Find tool window. To open the source code of the definition for editing and close the popup, click the icon F4. To open the definition without closing the popup, click the Ctrl+Enter.
The Parameter Info popup shows the names of parameters in method and function calls. DataGrip automatically shows a popup with all available method signatures within 1 second (1000 milliseconds) after you type an opening bracket in the editor, or select a method from the suggestions list.
You can explicitly invoke the popup if it has closed or if your IDE is configured not to show the popup automatically. To do so, press Ctrl+P (or click ).
Configure the parameter info popup
In the Settings/Preferences dialog Ctrl+Alt+S, go to .
In the Show the parameter info popup in ... milliseconds field, specify the time in milliseconds after which the popup should appear.
If you don't want the popup to appear automatically, clear the Show the parameter info popup in ... milliseconds checkbox.
Inlay hints are special markers that appear in the editor and provide you with additional information about your code, like the names of the parameters that a called method expects. Other types of hints inform you about annotations, method parameters, usages, and so on (depending on the language).
Some of the hints are enabled by default.
You can fine-tune inlay hints in.
Configure the parameter hints exception list
You can configure the list with exceptions for parameter hints.
In the Settings/Preferences dialog Ctrl+Alt+S, select and click the necessary language.
Select Parameter hints in the list in the middle section.
The options for configuring hints become available on the right.
Add cases for which you do not want to see the hints to the Blacklist section. To add a case, click the inline hint in your code, press Alt+Enter and select Do not show hints for current method.
Apply the changes and close the dialog.
You can get quick information for any symbol or method signature by means of the Quick Documentation popup.
Hover the mouse over the necessary symbol to view its documentation, or place the caret at the symbol and press Ctrl+Q ().
Press Ctrl+Q again to switch between the popup and the toolbar.
Click in the popup to change the font size, display the quick documentation toolbar, or go to the source code.
Disable quick documentation on mouseover
In the Settings/Preferences dialog Ctrl+Alt+S, go to and clear the Show quick documentation on mouse move checkbox.
You can also click in the popup and disable the Show on Mouse Move option.
In this case, to view documentation for a symbol at caret, press Ctrl+Q or selectfrom the main menu.
In DataGrip, you can identify the type of any variable and an expression in a popup. This is helpful if you don't need the full information on the code element.
Place the caret at the necessary code element and press Ctrl+Shift+P (or selectfrom the main menu).
