PlcLinkWidget Class Reference

The PlcLinkWidget class Provides a dedicated widget for linking a PLC-Slave to a PLC-Master IO entry. Displays all PLC-Masters as expandable items, each showing their IO entries. Each IO entry can only be linked to one slave. Already-linked entries are shown as struck-through and greyed out. More...

	PropertiesEditorWidget::setLiveEdit Set the editor in live edit mode. When an editor is in live edit mode, every change is applied immediately (no need to call apply). If live edit can be enabled, return true, or else false. By default this method does nothing and returns false (live edit is disabled). Inherited class of PropertiesEditorWidget must reimplement this method to manage the live edit mode.
