If you like to show a context menu only when user did a right mouse click, you can use the EventMonitor.LastMouseClickButton function to check mouse state.


Show a context menu based on a table with menu entries:

# go to layout with menu entries
Go to Layout [ “REP” (REP Reports) ]
# this script can be called with various groups
Set Variable [ $type ; Value: Get(ScriptParameter) ]
# make a new menu
Set Variable [ $menu ; Value: MBS( "Menu.CreateMenu") ]
# loop over records
Go to Record/Request/Page [ First ]
    # if group matches
    If [ REP Reports::Group = $type ]
        # add new menu item with title from table
        Set Variable [ $item ; Value: MBS( "MenuItem.CreateMenuItem"; REP Reports::LabelReport) ]
        # define which script to call if menu item is selected
        Set Variable [ $r ; Value: MBS( "MenuItem.SetScriptAction"; $item; Get(FileName); REP Reports::Script ) ]
        # add item to menu
        Set Variable [ $r ; Value: MBS( "Menu.AddItem"; $menu; $item ) ]
    End If
    # next record?
    Go to Record/Request/Page [ Next ; Exit after last ]
End Loop
# switch layout back
Go to Layout [ original layout ]
# Show menu
Set Variable [ $r ; Value: MBS( "Menu.PopUp"; $menu; "mouse") ]
# Cleanup memory
Set Variable [ $r ; Value: MBS( "Menu.Release"; $menu) ]

Show menu and show selection:

Set Variable [$menu; Value:MBS("Menu.CreateMenu")]
# create menu items...
Set Variable [$item; Value:MBS("MenuItem.CreateMenuItem"; "Hello World")]
Set Variable [$r; Value:MBS("MenuItem.SetTag"; $item; "secret value")]
Set Variable [$r; Value:MBS("Menu.AddItem"; $menu; $item)]
#show menu
Set Variable [$m; Value:MBS("Menu.PopUp"; $Menu; "mouse")]
#you selected something?
If [$m = 1]
    Set Variable [$selectedItem; Value:MBS("Menu.SelectedItem"; $menu)]
    Set Variable [$selectedTitle; Value:MBS("MenuItem.GetTitle"; $selectedItem)]
    Set Variable [$selectedTag; Value:MBS("MenuItem.GetTag"; $selectedItem)]
    Show Custom Dialog ["Auswahl"; $selectedItem & ¶ & $selectedTitle & ¶ & $selectedTag]
End If
Set Variable [$m; Value:MBS("Menu.Release"; $Menu; 1)]

Choose from menu with one Let statement:

// show menu with one let statement
Let ( [
// some list of menu entries
valuelist = "xxx¶yyy¶zzz" ;
// create menu from definition
menu = MBS ( "Menu.DefineQuickMenu"; "x" ; valuelist ) ;
// show menu near mouse
result = MBS ( "Menu.popup" ; menu ; "mouse" ) ;
// query selected item number
item = IF ( result = 1 ; MBS("Menu.SelectedItem"; menu) ) ;
// query title for that item
title = IF ( Length ( item > 0 ) ; MBS ( "MenuItem.GetTitle" ; item ) ) ;
// release memory
r = MBS ( "Menu.Release"; menu ) ] ;
