Selected ListViewItem and Up/Down arrows

3 posts in this topic

Hi group,

I didn't succed in finding an easy / elegant way to keep track of the selected item of a list view.

I mean that there is no problem to register an OnEvent function which fires when one item is selected but it works _only_ when the user is clicking on one item.

Once one item is selected, the user may well use the cursor movement keys (up/down arrows, page up/down, home/end) to change which item is selected.

The problem is that when it does, the "OnEvent" registered function does not get called.

Of course it is possible to register a private function for every message and then handle things from there, but this becomes a real mess with two or more listviews inside the same form and I'm sure there is a more efficient way.

I didn't find anything along the same line when searching the forum (probably due to inappropriate keyword selection).

Can some good soul point me toward the right solution. TIA.

I check for $LVN_ITEMCHANGED to see if an up or down key has been used. Please see the example in the help file for _GUICtrlListView_Create and uncomment the $LVN_ITEMCHANGED part to see how it works.

Thanks for the answer. Unfortunately, I'm using the std GUIx functions with on event functions, not the _GUIx and it is very likely to pose problems if both are mixed in the same application (due to different ID handling I believe). I'll look into how to use $LVN_ITEMCHANGED in my context.

Thank you for your hint.
