Custom Controls

A custom control is an area on a screen. You create them in the Screen Painter, and, like all other screen objects, they have a unique name. You use custom controls to embed controls. A control is a software component on the presentation server, which can be either an ActiveX control or a JavaBean, depending on the SAPgui you are using. They allow you to perform tasks, such as editing texts, locally on the presentation server. The control is driven by the application logic, which still runs on the application server.

The SAP Control Framework

The controls on the presentation server and the ABAP application programs on the application server communicate using the Structure link SAP Control Framework. This is programmed in ABAP Objects, and contains a set of global classes that you can find in the Class Browser under Basis ® Frontend services. These classes encapsulate the communication between the application server and presentation server, which is implemented using Remote Function Call.

All application controls are encapsulated in a global class. You can find the SAP Basis controls in the Class Browser under Basis ® Frontend Services or Basis ® Component Integration. Programs that use controls on a screen work with the methods and events of the global classes that encapsulates them.

Hi Rengith Skariah,

how is the display for image?

what code for it??

reply me soon,

s.suresh

Re: CUSTOM CONTROL ?

Former Member — Wed, 26 Mar 2008 09:19:52 GMT

You can display the image by calling the method load_picture_from_url

if you want to load the image from local system give the image path as url.

eg:

call method pic1->load_picture_from_url

exporting

url = 'file://C:\WINDOWS\Web\Wallpaper\home.jpg'

Where pic1 is the object of picture control.
