Double click on node

Former Member — Fri, 31 Oct 2008 16:09:17 GMT

Dear Colleagues !

I have a tree :

class lcl_tree definition inheriting from CL_COLUMN_TREE_MODEL.

...

data: G_TREE TYPE REF TO lcl_TREE.

...

CREATE OBJECT G_TREE

EXPORTING

NODE_SELECTION_MODE = CL_COLUMN_TREE_MODEL=>NODE_SEL_MODE_MULTIPLE

...

It works fine. I want to react to double click of a node:

event-eventid = CL_GUI_COLUMN_TREE=>EVENTID_NODE_DOUBLE_CLICK.

event-appl_event = 'X'.

APPEND event to events.

CALL METHOD G_TREE->SET_REGISTERED_EVENTS

EXPORTING

EVENTS = EVENTS

EXCEPTIONS

unknown_event = 1

ILLEGAL_EVENT_COMBINATION = 2.

But it doesn't happen anything.

I enhanced it:

CLASS gcl_events_hndl DEFINITION.

PUBLIC SECTION .

METHODS handle_node_double_click

FOR EVENT node_double_click

OF lcl_tree

IMPORTING node_key sender.

ENDCLASS.

DATA: l_event_receiver TYPE REF TO gcl_events_hndl.

...

CREATE OBJECT l_event_receiver.

SET HANDLER l_event_receiver->handle_node_double_click FOR g_tree.

And I have the same, nothing ...

Can You propose me anything ?

Thanks a lot and kind regards

Peter

Hi Peter,

I saw a std demo program (SAPCOLUMN_TREE_MODEL_DEMO) where they have implemented ur cl_column_tree_model class... Also dey hav implemented node_double_click event.....might be helpful..

Cheers,

Jose.

Hello Peter

Depending on "object" on which you double-click you either trigger event NODE_DOUBLE_CLICK or ITEM_DOUBLE_CLICK. The NODE_DOUBLE_CLICK event is only triggered if you click on the leftmost part of the node.

Have a look at my sample report ZUS_SDN_ALV_TREE_DEMO_1 in thread

Depending on where you double-click the raised event is displayed as I-message.

Regards

Uwe
