The application launcher in screenedge is hardcoded to:

            QDBusMessage::createMethodCall(QStringLiteral("org.kde.plasmashell"),
                                           QStringLiteral("/PlasmaShell"),
                                           QStringLiteral("org.kde.PlasmaShell"),
                                           QStringLiteral("activateLauncherMenu")

This is btw. the same command as for the modifier only shortcut in default.
If Latte is the one and only application launcher in a Plasma session, Plasmashell should open it when invoking activateLauncherMenu.

Martin Latte Dock is an external application and lives outside of
plasmashell, if this is hardcoded then I dont think it can be done anything
else. Except if the script can share somehow the Meta code.

Martin I have sent this: https://phabricator.kde.org/D11164

in case we can make edges aware of user-set modifier actions

You could provide a KWin script to launch latte dock.

can kwin scripts be assigned by the user to which edge to be activated like the original kwin edge actions?

Ok.. I will create a kwin script for this then... I just need to find out kwin scripts where to they store their settings, in order to give at least to the user the option to edit that file to set the Corner that wants the script to be executed...

It just works like any other edge action... You don't need a config file for it. You can have a look at minimizeAll script which uses edge activation already.

Martin I get an error from the following code:

file:///home/michail/.local/share/kwin/scripts/activatelattelaunchermenu/contents/ui/main.qml:48: ReferenceError: registerScreenEdge is not defined

do I miss something?

import QtQuick 2.0

import org.kde.kwin 2.0
import org.kde.latte 0.1 as Latte

Item {
    id: root

    property var registeredBorders: []

    Component.onCompleted: {
        options.configChanged.connect(init);

        init();
    }

    function init() {
        for (var i in registeredBorders) {
            unregisterScreenEdge(registeredBorders[i]);
        }

        registeredBorders = [];

        var borders = KWin.readConfig("BorderActivate", "").toString().split(",");
        for (var i in borders) {
            var border = parseInt(borders[i]);
            if (isFinite(border)) {
                registeredBorders.push(border);
                registerScreenEdge(border, activateLauncherMenu);
            }
        }
    }

    function activateLauncherMenu() {
        Latte.WindowSystem.activateLatteLauncherMenu();
    }
}

so sorry Martin... 

I have just found it how to use only javascript code through callDBus function and not qml at all...
