How to captur up & dpwn key presses and propagate events?

[alikim]

I have my own frame for events and if I write this code:

eframe:SetScript("OnKeyDown", eframe.OnKeyDown)
eframe:SetScript("OnKeyUp", eframe.OnKeyUp)
eframe:SetPropagateKeyboardInput(true)

then I don't capture Up event in my function, only Down.

I need to be able to capture both Down and Up events in my handlers and also propagate both events to the WorldFrame for the game to function normally.

Is there a way to do that?

Thanks!

The up handler doesn't fire when you propagate keyboard events. Running the bindings yourself is a protected action, so you can't go that route either.
One thing you might be able to do is register keybinds to issue a click to a button. See SetOverrideBindingClick(). I don't think it can differentiate up and down states.

If you mentioned what you're trying to implement, we may provide suggestions for other methods that may work instead.

Thank you, I implemented my own loot window that unregisters LootFrame from all events and normally when you click on a loot it then autoloots items following some pattern and then does CloseLoot(). What I also want it to do is if I CTRL-click on loot it would list all loot items and let me loot individually but then when I release CTRL it should CloseLoot().

If it's hard to implement, I can ofc just capture Down event and move when I'm done looting, I guess that will CloseLoot() as well but I wanted to press a button to let the addon know that I want manual loot and then release that button to let it know that it can CloseLoot().

You mean ctrl-clicking the mob in the world?
Anyways, just use the normal loot event LOOT_OPENED and check for IsControlKeyDown(), which when pressed/depressed triggers MODIFIER_STATE_CHANGED.
To prevent default auto-looting, use the ctrl key as the modifier to avoid autolooting.

Something like this perhaps:

local Frame = CreateFrame('Frame')
Frame:RegisterEvent('LOOT_OPENED')
Frame:SetScript('OnEvent', function(self, event, arg1, arg2)
    if(event == 'MODIFIER_STATE_CHANGED') then
        if((arg1 == 'LCTRL' or arg1 == 'RCTRL') and not arg2) then
            -- loot everything
            arg1 = true
            self:UnregisterEvent(event)
        else
            return
        end
    end
 
    if(arg1 and not IsControlKeyDown()) then
        LootFrame_InitAutoLootTable(LootFrame)
        LootFrame:SetScript('OnUpdate', LootFrame_OnUpdate)
        LootFrame.AutoLootDelay = LOOTFRAME_AUTOLOOT_DELAY
    else
        LootFrame.AutoLootDelay = 0
        LootFrame.AutoLootTable = nil
        self:RegisterEvent('MODIFIER_STATE_CHANGED')
    end
 
    LootFrame.page = 1
    LootFrame_Show(LootFrame)
 
    if(not LootFrame:IsShown()) then
        CloseLoot(not arg1 or IsControlKeyDown())
    end
end)
