Docking Container and CL_SALV_TREE

[Former Member]

Hi,

i get problems with this code.

i'm using docking container, not customer container.

...

CREATE OBJECT GR_DCONTAINER

EXPORTING

PARENT = CL_GUI_CONTAINER=>SCREEN0

SIDE = CL_GUI_DOCKING_CONTAINER=>DOCK_AT_LEFT

RATIO = 90.

*

PERFORM DYNP_SPLITTEN.

*

CREATE OBJECT GR_ALVGRID_RIGHT

EXPORTING

I_PARENT = O_PARENT_GRID_RIGHT.

...

TRY.

CL_SALV_TREE=>FACTORY(

EXPORTING

R_CONTAINER = O_PARENT_GRID_RIGHT

IMPORTING

R_SALV_TREE = GR_TREE

CHANGING

T_TABLE = ITAB ).

<b> CATCH CX_SALV_NO_NEW_DATA_ALLOWED CX_SALV_ERROR.

EXIT.</b>

ENDTRY.

*

i get the catch-event and the report ends.

Question: Does the ALV-TREE need customer container or can

i use docking container (how??).

thanks for help.

Sure, in this case, it is impelmented in a docking container hanging from a selection screen, but it is pretty much the same as hanging off a dynpro.

Hi Rich,

thanks for your answer. at the moment I'm in another project, therefore

i have to test it later.

Hi Rich,

thanks it works OK but i have a question too:

In a Grid-container i use this:

*

CALL METHOD GR_ALVGRID_RIGHT->SET_VISIBLE

EXPORTING

VISIBLE = SPACE.

Is there any method to the same when i have an tree, because this one

doesn't work with Tree.

Regards, Dieter

Try to set the visibility at the container level, meaning, the docking object as opposed to the tree object.

Hi Rich,

i try it like this:

First i do this:

CALL METHOD CL_SALV_TREE=>FACTORY

EXPORTING

R_CONTAINER = O_PARENT_GRID_RIGHT

IMPORTING

R_SALV_TREE = GR_TREE

CHANGING

T_TABLE = ITAB_TREE.

*

PERFORM TREE_HEADER.

*

PERFORM TREE_SPALTEN.

*

PERFORM FUNKTIONSTASTEN_SETZEN.

*

GR_TREE->DISPLAY( ).

It works OK.

when pressing a special button i will do this:

CALL METHOD O_PARENT_GRID_RIGHT->SET_VISIBLE

EXPORTING

VISIBLE = SPACE.

But it doesn't work.

Any idea, i think O_PARENT_GRID_RIGHT is OK. Isn't it?

Regards, Dieter
