dev_inspect_ctrl — Open a window to inspect one or more control variables.
dev_inspect_ctrl( : : Variable : )
dev_inspect_ctrl opens a variable inspect dialog to display the
contents of one or more control variables. The result of this action is
identical to selecting
Inspect from the context menu of control
variables in the variable window.
The standard variable inspection window displays the values in a table with some optional statistics. For some semantic types, e.g. matrices, a special representation exists and is used by default. For more information, see the chapter "Inspecting Variables" in the HDevelop User's Guide.
You can pass a tuple of variables in
Variable to open an
inspection window for multiple variables. It is also possible to override
the default inspection mode by including a string literal as the first
element of the tuple:
Show the values in the default inspection window even if the semantic type of the variable has a special representation.
Plot the values of numeric variables against their tuple index.
Plot the values of numeric variables as X-Y pairs. The number of variables must be even, with each pair of variables having the same length.
Normally, the contents of the dialog will be updated whenever the variables
change. However, the update behavior can be influenced by the operator
dev_update_var and the
Update Variable preference.
The dialog can be closed by pressing the
Close button or by calling
This operator is not supported for code export.
