Wheel Picker Editors
A wheel picker is a touch-friendly version of a multi-choice editor. Each rotating wheel in this editor provides a set of choices (items) for end-user selection. An item displayed in the center of its wheel is considered selected, and only one item per wheel can be selected at a time. Wheel items can display text and/or graphics to provide sufficient details on their respective choices.
End-users can rotate wheels using any of the following methods:
Swipe a wheel up or down;
Scroll the wheel located under the mouse pointer using the mouse wheel;
Press the number, Up Arrow, or Down Arrow key and navigate between wheels using the Left Arrow or Right Arrow keystroke.
Pressing the keys immediately changes the selected wheel value, while two other methods rotate the wheel with smooth animation.
Wheel picker editors include:
Generic value wheel picker editor (TdxWheelPicker);
Date-time wheel picker editors (TdxDateTimeWheelPicker and TdxDBDateTimeWheelPicker);
Numeric value wheel picker editors (TdxNumericWheelPicker and TdxDBNumericWheelPicker).
