Is there any way to have a multiple selection listview?

Any workarounds until we wait for the next release?

i tried changing the style with api calls but it does not work:

hlist=ListViewGadget(1, 10, 10, 100, 100)
oldstyle=getwindowlong_(hlist,#GWL_STYLE)
SetWindowlong_(hlist,#GWL_STYLE,oldstyle Or #LBS_MULTIPLESEL)

You need a SendMessage_() to the ListView.

Look for LB**** constants in the MS Platform SDK.

wich message do i have to send?

with the code i posted the listbox does not appear in the parent window, there are a lot of listbox messages:

but if the listbox is not there..., has this been done before?

Sorry, Justin - my fault.

Your error: "oldstyle Or #LBS_MULTIPLESEL"

"OR" is logical "OR" and gives back 0 or 1.
What you need here is a bitwise "OR", so
you have to use "|" for "OR".
AND, OR,.. = LOGICAL (return 0 or 1)
|, &,... = BITWISE

Complete example:

Code: Select all

OpenWindow(0,10,10,400,400,#PB_Window_SystemMenu,"ListBox")
CreateGadgetList(WindowID())
hlist=ListViewGadget(1, 10, 10, 380, 380)


oldstyle=getwindowlong_(hlist,#GWL_STYLE)
SetWindowlong_(hlist,#GWL_STYLE,oldstyle | #LBS_EXTENDEDSEL );| #LBS_MULTIPLESEL)


For a = 1 To 100
    AddGadgetItem(1,-1,"TEST "+Str(a))
Next a


Repeat
Until WaitWindowEvent() = #PB_EventCloseWindow

Start this little code and select the items.
Hold down SHIFT or CTRL (STRG) for selecting.

cya,

It does not work for me, the listbox appears but i can't make a multiple selection with ctrl or shift. In fact i can't change any listbox style, like LBS_NOSEL etc..

It seems i will have to wait until the new release, thanks in any case.
