About touch interactions supported during runtime

This topic provides some detail about unique touch behavior during runtime.

Multi-Touch Gestures

• Within a layout, content and pane level gestures are supported. However, if a content level gesture is in progress, no other types of gestures function in other panes during the duration of the content level gesture

• Excluding a scrunch gesture, all other types of gestures act on the contents of the pane within which the gesture occurs. Touch interactions within one pane are independent of interactions in other panes.

• Touch gestures interact with only a single WCC\WPF at a time. However, other non-WCC process graphics can interact with touch, at the same time.

• For WPF controls implementing iSupportTouch, the WPF control is responsible for ensuring multi-touch support.

  Touch Support for Apps

• The NavTreeControl and the NavBreadcrumbControl support single finger swipe and flick gestures. The hierarchical tree of the NavTreeControl can be scrolled up or down and left or right. Drop-down lists of the NavBreadcrumbControl can be shown or hidden by the supported gestures.

• Single finger swipe and flick gestures can be used to navigate the alarm hierarchy of the AlarmApp.

• Single finger swipe and flick gestures can be used to show or hide drop-down lists of the ContentPresenter and TitleBar apps.

• Native touch support on WPF controls is not supported. That is, if a user has implemented recognition of touch gestures within WPF, unless the user implements our ISupportTouch interface, it will not work.

• For WCC and WPF controls, without ISupportTouch implementation, touch will be converted to equivalent mouse gestures, where possible. These controls will respect the state of the Touch Lock if it does not implement ISupportTouch.

  Legacy ArchestrA .NET controls accessible from the Tools area do not implement ISupportTouch.

• Touch interactions along with mouse\keyboard actions are not supported.

  Scope of Touch Interactions

• Touch interactions initiated from within a pane continue to function when the gesture continues outside the boundaries of the pane.

• In the case of overlapping graphics, the topmost element configured with input animation is the target of the touch interaction.

• The behavior of double tap and long press are customizable through the Windows Control panel. AVEVA OMI ViewApps support operating system customizations.
