ListView control, is it possible the collapse/expand of groups ??

[Gianni]

Does anyone know if there is a way In AutoIt to make groups of a ListView control collapsible and expandable? (Here an example of what I mean)
Thanks

I never worked with Groups but _GUICtrlListView_SetGroupInfo  seems the func you are searching for.

@AutoBert is right.

And this is quite interesting feature (I never used it before).

Returns the combination of state values that are set. For example, if lParam is LVGS_COLLAPSED and the value returned is zero, the LVGS_COLLAPSED state is not set. Zero is returned if the group is not found.

 

btw.

Using the example from HelpFile for: 

_GUICtrlListView_SetGroupInfo

if you change:

; change this following line
    ; _GUICtrlListView_SetGroupInfo($idListview, 1, "New Group 1")
    
    ; to this two following line
    _GUICtrlListView_SetGroupInfo($idListview, 1, "New Group 1", 0, $LVGS_COLLAPSIBLE + $LVGS_COLLAPSED)
    _GUICtrlListView_SetGroupInfo($idListview, 2, "New Group 2", 0, $LVGS_COLLAPSIBLE + $LVGS_SELECTED)

 

Then you get exactly effect which you ask in OP.
