Delphi:TUpDownEx

Most practical uses of the Delphi TUpDown control require some means of direct input to be provided in addition to the ability to click on the up/down arrow buttons. Typically, developers do this by providing an edit box next to the TUpDown control. This is inconvenient in itself. Add to that the fact that the arrow buttons in TUpDown - which is merely a thin wrapper around the equivalent Windows control - do not scale well to all screen resolutions and you have a control that is not too usable. TUpDownEx resolves both these issues.

The key properties and events of TUpDownEx are listed below

• Increment :Word - The change in Position each time the ▲ or ▼ arrows are clicked.
• Maximum :Word - The maximum allowed value for Position.
• Minimum :Word - The minimum allowed value for Position.
• OnAdjust (Sender :TObject ;Position :Integer ) - The event triggered when Position is changed.
• Position :Word - The current value of Position.
• PositionEx :Word - Use this property to programmatically set Position without triggering the OnAdjust event.
