31.9 Tooltips

Code Place the mouse cursor over an identifier in the editor. A tooltip shows information about the element under cursor:


- the comment associated with the element's declaration (written above or the side), or the LRM documentation for predefined API


- scoping information for types (enclosing package and library)


- the full signature of subprograms


- direction of ports, etc.



Tooltips are available for all the entities, architectures, subprograms, etc. from the source code files that DVT analyzes in your project.
Folded regions Place the mouse cursor over the + sign of a folded code region. A tooltip shows the folded region contents.


Generic Values
Problems Place the mouse cursor over an error or warning annotation on the left vertical ruler of the editor. A tooltip shows the error or warning message.


If multiple problems are reported on the same line, an annotation list is displayed.


Subprogram Call Parameters Mapping


Ordered Port Connection Mapping
Place the editor cursor on a subprogram call argument and press Ctrl + Shift + Space. A tooltip lists all the subprogram declaration arguments along with their name, type, direction and default value. Move the editor cursor using the arrow keys to inspect argument mapping - the argument under cursor is always highlighted in boldface.



The same functionality is available for instance port connections.
