OTClient How to reorder TextList widgets?

[kuhi]

Hi

I'm trying to create the classic "Up" & "Down" buttons to reorganize this TextList widget:


Once clicking the "Up" button, the selected/focused list item, if it's not already the first one, it should raise 1 position in the list

I've tryed with this functions but none worked:

void raiseChild(UIWidgetPtr child);
void moveChildToIndex(const UIWidgetPtr& child, int index);
void reorderChildren(const std::vector<UIWidgetPtr>& childrens);

How I can achieve this one? Do I really need to destroy and create the widget manually? and how to create it on X position/index of the list?

PS: I'm doing this shit right now which is working, but there must be a better way to do it:

-- this table will hold a copy of the widgets
-- we will use this table as a reference and replicate it's data to the UI
waypointWidgetList = {}

-- finds a widget by it's "custom index"
-- required to assign index manually to the children object
-- example: mychildren.index = 1
function findChildByIndex(control, index)
    for i, v in pairs(control:getChildren()) do
        if v.index == index then
            return v
        end
    end

    return nil
end

-- escalate 1 position up a waypoint in the TextList
function moveWaypointUp()
    local focusedChild = waypointList:getFocusedChild()
    if focusedChild then
        local index = focusedChild.index
        print("index: " .. index)
        if index > 1 then                      
            local newpos = index - 1
            local aux = waypointWidgetList[newpos]
            waypointWidgetList[newpos] = waypointWidgetList[index]
            waypointWidgetList[index] = aux
            redrawWaypointList()      
            childToFocus = findChildByIndex(waypointList, newpos)
            if childToFocus then
                waypointList:focusChild(childToFocus)
            end
        end
    end
end

-- redraw the entire TextList from memory
function redrawWaypointList()  
    waypointList:destroyChildren()
    for i, waypoint in ipairs(waypointWidgetList) do
        local waypointLabel = g_ui.createWidget('WaypointLabel', waypointList)
        waypointLabel:setId(i)
        waypointLabel.index = i
        waypointLabel.description = waypoint.description
        waypointLabel:setText(waypoint.description)
        waypointLabel:setVisible(true)
    end  
end

Thanks <3

Adding some up and down with module manager using getFocusedChild, getChildIndex and moveChildToIndex

function move(offset) -- down is positive
    local focusedChild = moduleList:getFocusedChild()
    if focusedChild then
        local index=moduleList:getChildIndex(focusedChild)
        local newIndex=index+offset
        if newIndex < 0 then return end -- trying to move up when we are at the top
        moduleList:moveChildToIndex(focusedChild,newIndex)
    end
end

modulemanager.otui

  Button
    id: moduleMoveDownButton
    anchors.top: moduleReloadButton.bottom
    anchors.right: moduleReloadButton.right
    margin-top: 8
    !text: tr('Move down')
    enabled: true
    width: 90
    @onClick: modules.client_modulemanager.move(1)

  Button
    id: moduleMoveUpButton
    anchors.top: moduleReloadButton.bottom
    anchors.right: moduleUnloadButton.right
    margin-left: 10
    margin-top: 8
    !text: tr('Move Up')
    enabled: true
    width: 90
    @onClick: modules.client_modulemanager.move(-1)
