Menu to ListviewItem Control

This is a simplified example of something I've been experimenting with.

Perhaps it has been done before. I'm sure this could be done better.

Benefits:

- Set a specific "menu group" to a specific listview item control.

- Menus won't activate, unless a control is assigned a menu group.

Side Benefits:

-> No menu on listview description bar.

-> No menu on listview item group labels.

-> No menu on white space

Now, what I'd like to be able to do is make a "menu group" a "module" and then

attach that module to a listview item control.

This way, I only have to get each menu group once. (stored as a control?)

I tried it with a dummy control. I couldn't make it work.

Any ideas would be appreciated.

you should use the listview groups feature and set group membership for each item

native listview items have their pseudo control ID stored in the items param

find the index of the item you want to set a menu to and get the control ID for the

items menu with _GUICtrlListView_GetItemParam()

(listview items are not controls, they only have an index and if set, a command ID that can be used to track items in a sorted listview)

this example shows how you could use the groups feature instead of an item as a group label

and sets a listview item to a menu of choice by getting the native listview item pseudo control ID

you cannot use this with UDF created items, either stick with GUICtrlCreateListViewItem() or _GUICtrlListView_AddItem), _GUICtrlListView_AddSubItem() and _GUICtrlListView_InsertItem()

but never both at the same time.

OK I misunderstood you initially, I think this is what you want.

A variation on the example for GUICtrlCreateContextMenu(), but using Groups

rover,

Thanks for your time and examples. That will give me plenty to work with.

One more thing I would like to add if you or anyone else is interested.

The code I use for my listview contextmenus differs slightly from what I posted.

I use a WM_CONTEXTMENU handler for _GUICtrlMenu_TrackPopupMenu()

This way the NM_RCLICK notification returns immediately, and the WM_CONTEXTMENU handler,

has the blocking function TrackPopupMenu().

WM_CONTEXTMENU also has the screen coordinates, eliminating the need for _WinAPI_ClientToScreen().

This revised and more efficient version splits the menu between WM_CONTEXTMENU and WM_NOTIFY,

and has the advantage of getting the selected lv item and the client coordinates for the hittest

from the WM_NOTIFY NMITEMACTIVATE struct, and the screen coordinates for _GUICtrlMenu_TrackPopupMenu()

from WM_CONTEXTMENU lParam.

This can also be done entirely in the WM_CONTEXTMENU handler, but it requires

extra dllcalls (SendMessage() for getting the selected lv item and _WinAPI_ScreenToClient() for the hittest coordinates.

Addendum:

I never put listview contextmenu Appkey/Shift-F10 support in my code, so I've worked it out for my own use and added it here.

So, more code ends up in the WM_CONTEXTMENU handler after all...

You can remove the WM_SYSCOMMAND handler and the WM_CONTEXTMENU keyboard navigation code

if you don't require Appkey/Shift-F10 support or care about possible use

of shift-f10 on a listview item. *** (see notes in code) -remove the code in section below "If $lParam = -1 Then" ;Menu Appkey or Shift-F10

GUICtrlCreateButton("", 5, 410, 80, 25)
;***
;button added to allow changing focus with tab to demonstrate fix for annoying windows feature.
;the system menu will capture the keyboard focus from the listview
;when shift-f10 is used on an item without a contextmenu.

;when scrolling through the listview items with the arrow keys and using shift-f10
;instead of the menu appkey to pop up the selected items contextmenu, the system menu will be activated if
;the item does not have a contextmenu, this is standard windows behaviour.
;when the arrow key is next moved after using shift-f10 on an item without a contextmenu,
;the system menu will pop up and capture the keyboard.

;this behaviour can be changed by setting a flag when an item does not have a contextmenu
;and in WM_SYSCOMMAND check for the $SC_KEYMENU command, reset the flag and return zero.
