Tone, Looks like I spoke too soon, your example manifests the same problem I encountered: child controls of the tabitems aren't properly "moved" to the remaining tabitems when a tabitem is deleted. Look at the folder numbered *four* in your example, you'll see that it has the group control for folder # *THREE* in it. I expected that deleting a tabItem from a folder would "carry" the associated controls from all the succeeding tabitems with them, but instead the original assignments appear to be "copied" to the new tabitems; so, folders 1 & 2 have the proper (old) assignments of groups 1 & 2, but after deleting folder "three", folder named "four", in *position* number 3, shows group #3 in it. So, does anyone know if there is some way to "re-assign" controls after they've been created, so I could make the lists that are displayed with each tabitem be correct? I tried "destroy"ing the deleted tabitem, but it seems that may have actually destroyed the entire tabCONTROL. Also, in my actual program, I did delete the deleted folder handle from the handle variable, but that was just so correct data would be written to a file afterward, I don't think that could possibly have any effect on the association of control to parent. Dan Here's an example program I made to test what Tone showed me: -- code begins: -- code generated by Win32Lib IDE v0.10.4 include Win32Lib.ew without warning -- Window Window1 global constant Window1 = create( Window, "Window1", 0, Default, Default, 400, 300, 0 ) constant aStatusBar = create( StatusBar, "", Window1, 0, 25, 20, 20, 0) global constant aTabControl = create( TabControl, "TabControl", Window1, 48, 56, 292, 204, 0 ) for n = 1 to 5 do -- make 5 tab items: Tabs &= create(TabItem,"TabItem" & sprint(n), aTabControl, 0, 0, 0, 0, 0 ) end for for n = 1 to 5 do -- make 5 lists, one for each tab item: Lists &= create( List, "List" & sprint(n), Tabs[n], 24, 36, 248, 140, 0 ) end for global constant PushButtonDelTab = create( PushButton, "Delete Selected Tab Item", Window1, 88, 8, 184, 32, 0 ) end for procedure onClick_PushButtonDelTab() object tabSelected tabSelected = sendMessage(aTabControl,TCM_GETCURSEL, 0 ,0 ) setText(aStatusBar, sprint(tabSelected)) result = sendMessage(aTabControl,TCM_DELETEITEM,tabSelected, 0 ) if sendMessage(aTabControl,TCM_GETITEMCOUNT,0,0)= tabSelected then --last tab removed, so gotta backup one: result = sendMessage(aTabControl,TCM_SETCURSEL,tabSelected-1, 0 ) else result = sendMessage(aTabControl,TCM_SETCURSEL,tabSelected, 0 ) end if -- destroy(Lists[tabSelected+1])-- HANDLE ERROR, maybe destroys whole tabcontrol?? end procedure onClick[PushButtonDelTab] = routine_id("onClick_PushButtonDelTab") WinMain( Window1, Normal ) -- code ends ----- Original Message ----- From: <tone.skoda at siol.net> To: "EUforum" <EUforum at topica.com> Sent: Saturday, March 23, 2002 3:19 AM Subject: Re: [WIN32Lib] programmatically select tab item? > > Dan Moyer wrote: > > how would I use > > TCM_DELETEITEM & TCM_SETCURSEL > > in a program using Win32Lib? > > It's pretty simple, below is example.
