Further information about the sample.


TTabSlidingForm is the main form that represents the main window of the sample. It contains the following components:


  • The sample uses TImage to display and define 2D image components.
  • The sample uses TGestureManager class to manage all the touch and gesturing functionalities of the application.
  • The sample uses TChangeTabAction to implement tab change actions.

When you run the application, the sample shows the first TTabItem. The sample has 2 tab items, each one containing its own image. The first TTabItem displays its image. When the user slides the image, a TChangeTabAction is invoked to change to the other TTabItem, which displays its image.
