# DM_LISTSETMOUSEREACTION

The DM_LISTSETMOUSEREACTION message is sent to the dialog manager to set the behavior for handling mouse movement in a DI_LISTBOX list.

### Param1

The ID of the dialog item for which the behaviour is set.

### Param2

Can have one of the following values (listing of `FARLISTMOUSEREACTIONTYPE`):

Value | Description
--- | ---
LMRT_ONLYFOCUS | The list will react on mouse movement (change cursor position in the list) only when the item is in focus
LMRT_ALWAYS | The list will always react on mouse movement (change cursor position in the list). The example of such behavior is a list of found files in search results (`Alt-F7`)
LMRT_NEVER | The list will not react on mouse movement

### Return

Previous value.

### Controls

Control | Description
--- | ---
DI_LISTBOX | list

### Remarks

1. By default, a nonfocused DI_LISTBOX item reacts to mouse movement.
2. Far Manager 1.70 beta 5 and earlier: Param2 different of LMRT_ONLYFOCUS or LMRT_ALWAYS is similar to LMRT_ALWAYS value.
