Toolbars on mobile devices

Toolbars can be used to control action view rendering on mobile devices.

Rendering of default action views

On mobile devices, actions render usually as default action views, that show up implicitly in dedicated panes on the screen, following the platform native user interface rules.

When displaying forms on a mobile front-end, you can use a toolbar to control the rendering of the actions.

For more details, see Action views on mobile devices.

Toolbar action views in GBC chrome (Universal Rendering)

When using the GBC front-end on a mobile device (for example with Universal Rendering), it is possible to display the toolbar action views in the GBC chrome bar, by setting the "chrome" value in the toolBarPosition style attribute of the Window class:
<Style name="Window">
    <StyleAttribute name="toolBarPosition" value="chrome" />

Using toolbars for Androidâ„¢ devices (GMA)

On Android devices, a TOOLBAR can be used to define the action views that appear in the Android action bar.

Toolbar action views are listed first and ordered as they are defined in the TOOLBAR section, followed by the default action views for remaining actions that are not part of the TOOLBAR definition.

Using toolbars for iOS devices (GMI)

On iOS devices, a TOOLBAR renders as the iOS toolbar panel. This toolbar appears at the bottom of the screen, displaying a icon or text for each toolbar item. If there is not enough space to render all toobar items, a three-dot overflow icon appears on the right, to show up the remaining toolbar items.

The iosSeparatorStretch ToolBarSeparator style attribute can be used to stretch the toolbar separators to give more space between action buttons.

The background color for the iOS toolbar must be defined with the iosToolbarTintColor style attribute at the Window level.

In order to define the text color for iOS toolbar elements, define the iosTintColor style attribute at the Window level. However, other form elements such as Folder, Button, SpinEdit and RadioGroup will be impacted by the attribute defined for Window elements. To overwrite this, define another iosTintColor for the Form elements. For more details, see Decorate iOS UI elements.
