OTC Module – Debug UI

When you create new module, you always got problems with OTUI design. Why X element is on that position? What am I clicking?

I can’t solve all these problems, but my module can help you debug your UI without milion prints to console.

With this module you can easily view tree of elements on given position (under mouse cursor):

It also works before login:

modules/client_ui_debug/client_ui_debug.otmod

function onClientUiDebuggerMouseMove(mouseBindWidget, mousePos, mouseMove)
    local widgets = rootWidget:recursiveGetChildrenByPos(mousePos)

    local smallestWidget
    for _, widget in pairs(widgets) do
        if (widget:getId() ~= 'highlightWidget' and widget:getId() ~= 'toolTip') then
            if (not smallestWidget or
                    (widget:getSize().width <= smallestWidget:getSize().width and widget:getSize().height <= smallestWidget:getSize().height)
            ) then
                smallestWidget = widget
            end
        end
    end
    if smallestWidget then
        clientUiDebugHighlightWidget:setPosition(smallestWidget:getPosition())
        clientUiDebugHighlightWidget:setSize(smallestWidget:getSize())
        clientUiDebugHighlightWidget:raise()
    end

    local widgetNames = {}
    for wi = #widgets, 1, -1 do
        local widget = widgets[wi]
        if (widget:getId() ~= 'highlightWidget') then
            table.insert(widgetNames, widget:getClassName() .. '#' .. widget:getId())
        end
    end
    clientUiDebugLabel:setText(table.concat(widgetNames, " -> "))
end

function init()
    connect(rootWidget, {
        onMouseMove = onClientUiDebuggerMouseMove,
    })
    clientUiDebug = g_ui.displayUI('client_ui_debug')
    clientUiDebugLabel = clientUiDebug:getChildById('clientUiDebugLabel')
    clientUiDebugHighlightWidget = g_ui.createWidget('HighlightWidget', rootWidget)
end

function terminate()
    disconnect(rootWidget, {
        onMouseMove = onClientUiDebuggerMouseMove,
    })
    clientUiDebug:destroy()
    clientUiDebugHighlightWidget:destroy()
end
