Touch властивість

Touch is part of the published TPdfView surface. The Syntax section mirrors Lib\PDFium.pas; when the declaration omits an explicit type, the type is inherited from the underlying VCL/LCL control.

Use it for normal component configuration in the same situations where the corresponding framework property would be configured. It does not load, save, render, or mutate PDF page content by itself.

• The member is published for design-time and streaming compatibility when the target framework supports it.
• Low-level input and layout behavior follows the active VCL/LCL implementation.
• Changing the property does not alter the PDF document data.

Configure this member as you would configure the corresponding property on the inherited control.
