Property Documentation

[since Felgo 3.10.0] autoUpdate : bool

Whether the control synchronizes with the target to automatically update when the model or sectionProperty changes. Defaults to true. Deactivate this setting to manually update the view with the update() function.

This property was introduced in Felgo 3.10.0.

See also update().

[since Felgo 3.9.0] bottomMargin : real

Add additional bottom margin below the last section. This can be used to respect the bottom safe area on mobile devices. The default value is 0.

This property was introduced in Felgo 3.9.0.

[since Felgo 3.10.0] caseSensitive : bool

Set to true to operate the control in case-sensitive mode. The control then only counts entries that start with an uppercase section character.

This property was introduced in Felgo 3.10.0.

[since Felgo 3.10.0] ignoreDiacritics : bool

If active, diacritical marks are ignored, which makes the control insensitive to accent characters. For example, letters like Ä and ê are countent as their un-accented variants A and e then.

This property was introduced in Felgo 3.10.0.

sectionProperty : string

The name of the section property within the target ListView's model. The target section.property is used by default. Using a custom section property for the SectionSelect allows to use different sections for the SectionSelect control and the actual sections displayed in the ListView.

target : Item

The target ListView of the SectionSelect control. The SectionSelect will read the target's model data and move the list to the chosen section when clicked.

Signal Documentation

[since Felgo 3.10.0] selected(string character, int itemIndex)

Fires whenever the user touches the control on a valid section that exists in the target model.

Note: The corresponding handler is onSelected.

This signal was introduced in Felgo 3.10.0.

Method Documentation

[since Felgo 3.10.0] void update()

Calling this method updates the SectionSelect to reflect the entries of the target view. This synchronization is done automatically at component creation and whenever the sectionProperty or target changes. To manually control all view updates, deactivate the autoUpdate property.

This method was introduced in Felgo 3.10.0.
