Listbox event ?

karageurkarageur Junior MemberPosts: 97

Is there a possibility to use listbox not only for viewing but also for getting event like PUSH on a cell/row/column?
There are no problems to fill it, sort, view and so on.
But how to get the TP event when pushing it?
Notifications are empty when manipulating with it.

    Hey, guys!
    What elements do you use to make a common list for choosing a song/movie from this list?
    If listbox is not capable of sending "choosed item" then what else to use? Many buttons arranged in columns - reinventing the wheel ... ? Arrhhh!

    One of the fields you can assign to a listbox row is a port/channel. This then sends the standard push/hold/release event to the relevant port/channel when the row is pushed. There is no way of assigning multiple channels to a single row as far as I'm aware.

    SEND_COMMAND dvTP,"'^LDN-4,1,5,Browse'" //New 5 column list on port 4
    SEND_COMMAND dvTP,"'^LDT-1,1,0,1,0,0,3'" //Five columns are text/bitmap/text/text/channel
    SEND_COMMAND dvTP,"'^LDA-1,0,1,bitmap.png,text1,text2,"4,1"'" //Send data to row 1 inc port/channel 4:1

    I recommend you download the TPC listbox demo available in their forum as it's really useful - much more so than the sparse data available in PI.

    OMG, I did it!
    I have assigned each row with it's own Port & Channel via code.. //
    ^LDD-1 - wipe-out the list
    ^LDN-33,1,5,Servers - tell the list (List Table Port in TPDesign - 33) how much columns are used (5)
    ^LDT-1,1,0,0,0,0,3 - the type of each column. The important thing here is (3) - it's port/channel column type that is assinged to 5th column (the list table itself can have less than 5 columns - for example 4 so that port/channel column was hidden)
    ^LDA-1,1,1,2,3,4,"33,45" - fill the columns with data - the last item ("33,45" in 5th column) is port/channel assigned dynamically.
    That's it. Now one has to settle the list feedback issue somehow...
