Quickly Enable Smooth Sliding Effects Between Tabs In Delphi Apps For Android And iOS

The FMX.TabSlideTransition Sample adds dynamism to the use of tab sliding effects in mobile applications.

Location

You can find the TabSlideTransition sample project at:

• Start | Programs | Embarcadero RAD Studio Sydney | Samples and navigate to:
  • Object PascalMulti-Device SamplesUser InterfaceTabSlideTransition
  • CPPMulti-Device SamplesUser InterfaceTabSlideTransition
• Subversion Repository:
  • You can find Delphi and C++ code samples in GitHub Repositories. Search by name into the samples repositories according to your RAD Studio version.

How to Use the Sample

1. Navigate to the one of the locations given above, and open:
   • Delphi: TabSlidingProject.dproj
   • C++: TabSlidingProject.cbproj
2. Press F9 or choose Run > Run.

Classes

TabSlideTransitionFrmBase represents the main window of the sample. It contains the following components:

• A ActionList1 object containing:
  • PreviousTabAction and NextTabAction objects.
• A GestureManager1 object.
• A TabControl1 object with five TabItem objects:
  • The first TabItem1 tab item contains:
  A NameList list box containing FirstName and LastName list box items containing edit controls providing input fields.
  • Other four TabItem2, TabItem3, TabItem4, and TabItem5 tab items contain:
  List boxes containing three PersonalInfoList, EducationList, and WorkList list box items and the memo control containing edit and combo box controls providing input controls.
• A ToolBar1 toolbar containing:
  • The Back and Next buttons.

Implementation

• When you run the application, the first TabItem1 is displayed. Before going to any of the next tab items, all fields on the tab must be completed. Otherwise, the Next button is not Enabled.
• On pressing the Next or Back buttons on the toolbar tab control, the NextTabAction or

PreviousTabAction tab switching actions are invoked.

• To assign these actions to toolbar buttons, in the Structure view select a button, for example Next ({Code|Button1}}). In the Object Inspector, select the Action node, click the down arrow on the right, and assign New Standard Action > Tab > TNextTabAction to the Action property. To set the TabControl tab control in which to make switching of active tabs, in the Object Inspector, expand the Action node, select the TabControl item, and click the down arrow on the right. From the list, select the TabControl1 tab control.
• To enable or disable the Keyboard Toolbar, the SetToolbarEnabled method is used.
• The Keyboard Toolbar is implicitly hidden, appearing only when completing information in TEdit objects. Setting the visibility is achieved using the following method: SetHideKeyboardButtonVisibility.
