Disable Widget

This section describes the Disable Widget functionality in HIL SCADA

HIL SCADA allows individual widgets to be disabled. Each disabled widget will be visually marked within the UI to clearly indicate its disabled state (Figure 1).

When a widget is disabled, the following behavior applies:

• Signals associated with the widget (analog, digital, streaming, etc.) will not be collected.
• Widget handlers and macros will not be executed.
• Local name-space resolution will not be performed (applicable to group-like widgets).
• Some user interaction with the widget will not be possible (e.g., selecting UI controls on the widget).

However, even when a widget is disabled, certain interactions remain available, including moving, resizing, copy/cut/paste operations, as well as modifying parameters within the Property dialog.

Note: Disabling a group-like widget (Group or Sub-Panel widget) will disable all of its child widgets. The same applies to the enable operation - enabling a group-like widget will enable all of its child widgets

Note: A widget can only be enabled if its parent widget is also enabled.

Disabling/Enabling a Widget

There are multiple ways to disable or enable a widget in HIL SCADA - using the SCADA UI or the SCADA API.

Disabling/Enabling a Widget via SCADA UI

Context menu: Select the desired widget, right-click to open the context menu, and choose the Disable selected widgets or Enable selected widgets action (Figure 2).

Keyboard shortcuts: When widget is selected, use the following shortcuts:

• Shift+D - Disable the widget
• Shift+E - Enable the widget

Panel Explorer: (Panel Explorer Dock) To disable or enable a widget using the Panel Explorer, right-click the widget name and select the Disable widget or Enable widget action from the context menu (Figure 3).

Disabling/Enabling a Widget via SCADA API

In addition to the SCADA UI, widgets can be disabled or enabled programmatically via the SCADA API using the set_property_value() function with the new PROP_ENABLED property.
