dev_inspect_ctrl — 打开一个窗口以检查一个或多个控制变量。
dev_inspect_ctrl( : : Variable : )
dev_inspect_ctrl opens an inspection window to display the
contents of one or more control variables.
The standard inspection window displays the variable values with some optional
statistics in a table. For some semantic types a special representation
exists, e.g., functions are displayed as function plot 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 window contents 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 window can be closed by pressing the Close button or by calling
dev_close_inspect_ctrl。
