C# and AX Development: How show a popup menu in AX/Axapta

==============

In the following sample, I have duplicated the sysAOT form, and I have overrode the context method for the tree control. Here the code to show the system context menu for any selected treeNode.

PopupMenu       popupMenu;
SysContextMenu  sysContextMenu;
int idx = tree.getFirstSelected();
TreeNode treeNode = tree.getItem(idx).data();
 
// add some custom menu items
int editMenu;
int choice;
;
 
// current selected treeNode is valid ?
if (treeNode == null)
    return;
 
// create the SysContextMenu for this TreeNode
sysContextMenu = new SysContextMenuTreeNode(treeNode);
 
// System API call to build the popup menu
popupMenu = sysContextMenu.buildMenu(this.hWnd());
 
// Add a custom edit menu
popupMenu.insertBreak();
editMenu = popupMenu.insertItem("Edit");
 
// showing menu
choice = popupMenu.draw();
 
// Showing and processing this popupMenu
if (!sysContextMenu.runMenu(choice, sysContextMenu))
{
    if (choice == editMenu)
    {
        SysInfoAction_Editor::newOpen(treeNode.treeNodePath()).run();
    }
}

But, looking in depth, I found that the sysAotFind form can be used to get some practical sample on how we can create our custom popup menu. Here an adapted version of that code to the previous SysAOT2 form(method context within control tree):

// current selected treeNode
int idx = tree.getFirstSelected();
TreeNode treeNode = tree.getItem(idx).data();
 
// We want to build, a popup menu, with a custom submenu and another
// sysContextMenu as submenu (add-ins menu item)
PopupMenu       popupMenu      = new PopupMenu(this.hWnd());
PopupMenu       copyMenu       = new PopupMenu(this.hWnd(), popupMenu);
PopupMenu       subSysContextMenu;
SysContextMenu  sysContextMenu;
 
// Menu options
int             open;
int             editMethod;
int             copyName;
int             copyPath;
int             copyFullPath;
int             copyAll;
int             choice;
int             find;
;
 
// current selected treeNode is valid ?
if (treeNode == null)
    return;
 
// create the SysContextMenu for this TreeNode
sysContextMenu = new SysContextMenuTreeNode(treeNode);
 
//---------------------------------
// Building the menu
open = popupMenu.insertItem("Open");
popupMenu.insertBreak();
editMethod = popupMenu.insertItem("Edit");
 
copyName        = copyMenu.insertItem("Copy Name");
copyPath        = copyMenu.insertItem("Copy Path");
copyFullPath    = copyMenu.insertItem("Copy FullPath");
copyAll         = copyMenu.insertItem("Copy All");
 
popupMenu.insertPopupMenu("Copy", copyMenu);
popupMenu.insertBreak();
 
find = popupMenu.insertItem("Find");
popupMenu.insertBreak();
 
subSysContextMenu = sysContextMenu.buildMenu(this.hWnd(), popupMenu);
popupMenu.insertPopupMenu("Add-ins", subSysContextMenu);
//---------------------------------
 
// Now, showing the popup menu
choice = popupMenu.draw();
 
// processing option
if (!sysContextMenu.runMenu(choice, sysContextMenu))
{
    switch (choice)
    {
        case open:
            // to implement
            break;
 
        case editMethod:
            SysInfoAction_Editor::newOpen(treeNode.treeNodePath()).run();
            break;
 
        case find:
            // to implement
            break;
 
        case copyName, copyPath, copyFullPath, copyAll:
            // to implement
            break;
    }
}

Также можно посмотреть на реализацию плагинов к Табаксу:

Там строится контекстное меню, и даже еще и с картинками.

Небольшой комментарий:

в 4-ой аксапте когда попуп меню строится через PopuMenu класс - сразу теряется стиль меню (Office 2003), а когда вызывется super(handle) - то меню выглядит как надо. Поэтому когда потребовалось добавить свой пункт меню, причём в определённую позицию (PopupMenu.insertItem - на самом деле делает AppendMenu - добавление в конце) пришлось прямо на контроле (StringEdit ячейке Grid) писать:

//TE-rko
public int showContextMenu(int _menuHandle)
{
    #WinApi
    #define.filterByLocaLang(100)
    #define.UserDLL('USER32')
    int selection;

    DLL         _winApiDLL      = new DLL(#UserDLL);
    DLLFunction _insertMenu    = new DLLFunction(_winApiDLL, 'InsertMenuW');

    ;
    _insertMenu.returns(ExtTypes::DWord);
    _insertMenu.arg(ExtTypes::DWord,
                     ExtTypes::DWord,
                     ExtTypes::DWord,
                     ExtTypes::DWord,
                     ExtTypes::WString);

    _insertMenu.call(_menuHandle, 2, #MF_BYPOSITION + #MF_STRING, #filterByLocaLang, "Filter by local name");

    selection = super(_menuHandle);

     switch (selection)
    {
        case #filterByLocaLang:
            element.filterByLocalLang(); //моя реакция на меню
            break;
    }

    return selection;
}
