Elevation property

This documentation is valid for:

Used by the developer to configure the shadows cast by controls.

Scope

Objects: Theme for Smart Devices
Platforms: Smart Devices(Android, IOS)
Controls: Attribute/Variable, Button, Grid, Group, Image, Tab, Table, Text Block

Description

This property accepts positive numerical values indicating how much shadow the developers want to show.
By default, its value is empty (semantically represents 0).

Notes

Available for Android 5.0 or higher.
Available from GeneXus 15 upgrade 12
To see the effect, the background color should be opaque.
The space for the control and its shadow must be smaller than its container cell.
If there are controls inside a Canvas with Elevation and ZOrder properties set, the difference between two controls with the same ZOrder is their Elevation.
To change the elevation at runtime, change the theme class. For instance, if you have set the Button class for a button control, you can type:
```
Button1.Class = ThemeClass:ButtonWithElevation
```
where ButtonWithElevation is a theme class with Elevation property set.

Runtime/Design time

This property applies both at run-time and at design-time.

Samples

Following Material Design guidelines, the examples below are based on customized buttons.

Previously, in the Theme classes section for Android, these settings were made:

Border Style = solid
Border Color = 14BBCC
Border Width = 1dip
Border Radius = 60 dips
Background Color = 14BBCC

Next, after dragging the button control from the Toolbox to an abstract layout of a Panel or Work With for Smart Devices, these settings were made:

Width = 40
Height = 40
Image = <an_add_to_cart_icon>
Class = <class_previously_created>

With this configuration, the button will have a rounded look with a small icon inside it.

Finally, after changing the Elevation property in the Theme class, the effects achieved are shown in the following table:

	Value	by default	5	10	20
	Effect

Availability

This property is available since GeneXus 15.
