CListCtrl with "tap and hold" and selecting item with a "tap"

Frank S

Hi, is there the possibility to select and highlight an item in the ListCtrl only with a tap on it and how can i use "tap and hold" with a CListCtrl? And is that even possible with Win CE < 3.0? Thanks, Frank _____ easySMS for pocket PC _____ www.Siedler-Net.de/WinCE/easySMS/

Hi, Check my article on this subject: Handling tap-and-hold[^]. In this article I explain a technique that allows you to select an item using a tap while keeping the tap-and-hold capability: you have to correctly handle the NM_CLICK notification. This notification will be sent after a normal tap and after a tap-and-hold operation. When you handle the tap-and-hold (through the GN_CONTEXTMENU notification), use a flag to store this state, ans test it in the NM_CLICK handler. If the flag is TRUE, this is a tap-and-hold, otherwise it is a normal tap. I know nothing about Windows CE < 3.0... Hope this helps.

Hi, i have read your article ... but it doesn't work with my DialogBox Window which has a CListCtrl Window inside. That was build with the Resource Manager. So, if i tap on the CListCtrl Window nothing happens, only if i tap beside where the DialogWindow is. The message is only handled if i tap on the Dialog Window of my App. Is there the possibility to handle the messages even if i tap on a Window inside that Dialog Window? Perhaps with SetCapture() ?

What is the platform you are working on? I'm just trying to figure out what is happening to you. My approach has worked as well for dialogs, but it was tested only under Pocket PC 2002.

Well, that Dialog looks like that: http://www.siedler-net.de/WinCE/easySMS/docu/V_1-50/easySMS_FOLDERS.gif in my Dialog window are these Controls. And i have tested it with WinCE 3.0. Greetings, Frank _____ easySMS for pocket PC _____ www.Siedler-Net.de/WinCE/easySMS/

I see you are using Pocket PC 2000. I still do not understand why the list control does not adequately respond to the tap-and-hold. There can be only three answers for this: 1-The PPC2K version of the control does not handle tap-and-hold natively (I doubt it). 2-You are overriding the WM_LBUTTONDOWN message and are not allowing the control's window procedure to handle it. 3-I have no idea what is happening... :~

Hi, i think, the CListCtrl-Subwindow in the Dialog Window doesn't send the stylus tap-recognition to the Dialog Window, so that the notification of WM_LBUTTONDOWN doesn't work. I only can handle the Click-operation in that window (tap and release) if i tap on the ListCtrl-box the selection isn't changing, only by a click it's changing. I think that's the problem, but i don't know how to handle ... :-( Greetings, Frank _____ easySMS for pocket PC _____ www.Siedler-Net.de/WinCE/easySMS/

Is it possible to handle these input messages from the stylus with PreTranslateMessage(MSG* pMsg) ? I have figured out, that if i use that function, i can handle the WM_LBUTTONDOWN message even if i click on the ListCtrl-window, and not only on the dialog box window. But now the problem is, that i have to know, which window in the dialog box is active and should be handled! Because the other Windows should be handled normal. And is it normal, that the selected item in a listbox is only changing, if you are clicking on it? With normal windows applications, you only have to tap on it and it's quite changing.
