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. It is possible to pass several variables together in one expression, e.g., within a tuple. The standard variable inspect shows a table with one column for the values of one variable. In addition some statistics can be displayed for every variable.
For some selected semantic variable types a specific variable inspect windows is opened:
For every matrix object one inspect window is opened that orders the matrix values in a table.
For every image acquistion handle one inspect window is opened, that shows the most important image acquisition parameters and allows to switch a live grab mode on or off.
Normally, the contents of the dialog will be updated whenever the variable changes. 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 dev_close_inspect_ctrl.
This operator is not supported for code export.
