sap.m Library Buttons :
The sap.m library is mostly used in the latest applications as it is browser independent and provides an variety of controls and properties which enrich user experience.
It is responsive. It is used when the user has to trigger some actions. The types of sap.m.Button are :
<Button type="Accept" text="Accept Button" />
Menu Button :
It is used for opening an menu. It is like an drop down list of actions.
<MenuItem text="Edit" icon="sap-icon://edit" />
<MenuItem text="Save" icon="sap-icon://save" />
<MenuItem text="Open" icon="sap-icon://open-folder" />
Paging Button :
It is used for pagination and navigation between items or entites. The position and count property of this control is used for the navigation.
Radio Button :
RadioButton is a control similar to a checkbox, but it allows the user to choose only one of the predefined set of options. They can have value state, and be arranged in both vertically and horizontally.
Radio Button Group:
It is a wrapper for a group of sap.m.RadioButton, it can be used as an single UI Element. This is primarily used when an single event handler is to be used for the entire group instead of individual event handlers.
It is an horizontal control made up of multiple buttons. We use the items aggregration to display the list of buttons.
<SegmentedButtonItem text="Year" key="Year" />
<SegmentedButtonItem text="Month" />
<SegmentedButtonItem text="Day" />
Toggle Button :
Initial State : On Click :
A toggle button has basically two states i.e. pressed state and normal state. It is just an enhancement on the sap.m.Button. When we click on the toggle button, to goes to the pressed state, on clicking it again it comes back to the normal state.
sap.ui.commons library :
Most of the controls in this library is deprecated as they are not browser/device independent and do not have the modern UX. Now we mostly use the sap.m library for application development.
