Hello,

1) Yes.Custom control is a type of a container.A standalone instance of a control cannot be created on the presentation server.Two components should always be present-a screen and a special control called a container control.The container control attaches a control to the screen.Some of the commonly used containers are custom container,splitter container,docking container.CUSTOM CONTAINER is of class cl_gui_custom_container.

2)Yes.To attach any control like tree or text edit,we need to have a container.We can use various containers but custom container is most commonly used.

3)We have to use classes.For tree,we can use cl_gui_alv_tree.For text editor we use cl_gui_textedit.We need to create a container in the screen layout by using the icon with C written on it.

4)The automation controller is run from ABAP using cl_gui_CFW,cl_gui_object,cl_gui_control.

Cl_gui_object is just a super class of cl_gui_control.

<b>You will get sample programs for all the containers and the controls on this link:
