touchscreen and listview

Recommended Posts

Champak

I'm working with a touchscreen (not a multipoint screen) and I need to be able to do a couple things with the listview that I don't know how to accomplish.

1/ I need to be able to select multiple things by pressing the items without pressing the control button, then obviously unselect the items if I press one of the highlighted items again. Is this possible?

2/ I need to be able to drag an item or group of items to another point in the list. I can do that with a mouse with slight difficulty because the mouse icon has to be placed just right, but I can't seem to do that with my finger, the screen wont scroll up or down beyond what is already displayed (I'm assuming this one cant be fixed and is inherent in working with a touchscreen...just hoping).

Hi,

For the first thing here you go :

#include <GUIConstants.au3>
#include <GUIListView.au3>

$hGUI = GUICreate("MyGUI")

$iLw1 = GUICtrlCreateListView("Col1|Col2", 10, 10, 380, 380, -1, BitOR($LVS_EX_FULLROWSELECT, $LVS_EX_CHECKBOXES))

For $i = 1 To 10
    GUICtrlCreateListViewItem($i & "|" & Chr($i + 80), $iLw1)
Next

GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")
GUISetState(@SW_SHOW)

While GUIGetMsg() <> $GUI_EVENT_CLOSE
    Sleep(10)
WEnd

Func WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam)
    Local $tNMHDR = DllStructCreate($tagNMHDR, $lParam)

    Local $hWndFrom = DllStructGetData($tNMHDR, "hWndFrom")
    Local $iIDFrom = DllStructGetData($tNMHDR, "IDFrom")
    Local $iCode = DllStructGetData($tNMHDR, "Code")

    Switch $iIDFrom
        Case $iLw1
            Switch $iCode
                Case $NM_CLICK
                    Local $tInfo = DllStructCreate($tagNMITEMACTIVATE, $lParam)
                    Local $iIndex = DllStructGetData($tInfo, "Index")

                    _GUICtrlListView_SetItemChecked($hWndFrom, $iIndex, Not _GUICtrlListView_GetItemChecked($hWndFrom, $iIndex))
            EndSwitch
    EndSwitch

    Return $GUI_RUNDEFMSG
EndFunc

Thanks. I don't understand your example. Are you trying to show me to use checkboxes as my point of reference in order to move multiple items...or do whatever I want with them...instead of keeping the list rows highlighted when I click on them? If you are, I already thought about doing that, but didn't want to go that route. I just want to keep my two column listview the way it is and keep whatever I click on highlighted until/if I click on it again...or close the window.

My bad I read too fast.

What do you mean by "select multiple things by pressing the items without pressing the control button" ?

Generally when you try to select multiple things, you have to hold down the ctrl button on the keyboard while you click on the item with the mouse. Using the touchscreen and no keyboard I can't do that. So I need to be able to select multiple items without clicking the ctrl.

Champak,

How do you select multiple items in other apps using this touchscreen - in Explorer for example? :huh:

You'd pick an open space in explorer and start dragging from there to highlight all of the files you want, the same way you would with a mouse.

That's not what you were asking about in the original post, you asked if you could select multiple items using the touchscreen without holding the CTRL key. What you just said is not what you asked. You can use a touch screen just like a mouse in the same way as you do the mouse, press and hold on the screen and drag your finger over multiple items in the listview. I don't see how this relates to AutoIt in any way.

I know what I just said had nothing to do with what I asked for. What I just said was replying to Melba's specific question. I know how a touchscreen works seeing how I use it everyday, and if what you said worked I wouldn't be here asking this question. This is autoit related because it happens in my app. Holding onto things and dragging my finger drags them to a different position in the list which you should have realized reading my op so closely (2).

I suppose you could use a Windows message that you monitor to see if the listview has been clicked on. Although I have no idea how you'd differentiate between a single press selecting an item and another one clicking and dragging.

I think you are right when I think about it. So I think I'll do it that way with window messaging and then instead of using a dragging option, use an input and button function where I would input the index starting point I want everything moved to and press a button to execute, and when it's moved, the new position is brought into focus on the list view. Both problems solved. Now I just need some time to figure out how to do it. Thanks.

This is what I have so far, not succeeding. My issues are commented.

    GUICtrlCreateListViewItem($i & "|" & Chr($i + 80), $iLw1)

    Sleep(10)

                            _GUICtrlListView_SetItemSelected ($iLw1, $ListArray, False);==This should unhighlight the item if I click on it a second time
                            Return
                        EndIf
                    Next

                    _ArrayAdd($TotalList, $ListArray)

                            _GUICtrlListView_SetItemSelected($iLw1, $TotalList[$j]);==This should highlight all the items in the array
                        Next
                    EndIf
                    ;_ArrayDisplay($TotalList)
            EndSwitch
    EndSwitch

    Return $GUI_RUNDEFMSG
EndFunc

Also as a side note, I don't know if this is a bug or not, but I've always had this issue with autoit (or scite) but couldn't come up with a condense reproduction outside of my app because I didn't know what was actually causing it. If you uncomment that _arraydisplay at the end, it will cause the script to have a fit and exit. It only seems to happen at certain points within certain functions. This is only one example, I've seen it happen around other functions. Is this a known bug? This has happened on all the computers I've had, all versions of autoit I've had since 2009, fresh hard drive installs, Win xp and 7.

You can't use a blocking function like _ArrayDisplay inside a window's message function like that, it usually hard locks the computer or crashes the script/computer.

You can do this :

AdlibRegister("MyFunc", 0)
            EndSwitch
    EndSwitch

    Return $GUI_RUNDEFMSG
EndFunc

Func MyFunc()
    AdlibUnRegister("MyFunc")
    Local Static $fCall = False
    If $fCall Then Return 0
    $fCall = True
    _ArrayDisplay($TotalList) ;make $Totallist as global
    $fCall = False
EndFunc

The call flag is to avoid the function to be called multiple times before the arraydisplay is closed, so you will only have one arraydisplay at time.

BrewManNH, that maybe so, but that is just one example. I've had it happen in regular "self created" functions. I can't readily find one now, because when it happens I'm basically forced to move the arraydisplay somewhere else later in the function to prevent it from happening. If I come across one again, I'll try to condense the function and post it. But it's beyond that example of messaging functions.

FireFox, I'm not seeing your entire post, it looks like some of it is cut off.

Nope, I was lazy to add "..." at the first line. I thought you whould understand. Just add your code before ;)

oh, you were trying to show me a way around the arraydisplay issue. I thought you were missing code because I thought you were actually fixing my main issue lol. That's cool, thanks.

Figured it out. Apparently I needed the Number() function around the indices to be highlighted otherwise it returns false.
