[Code-Discussion] UICallbacks

[conde2]

So I come here to show a simple code, if the community accepts the idea, I will be continuing the project.
This code will allow call some functions in the UI.
An example of a function that can be called is when you release a MiniWindow in LeftPanel / RightPanel, allowing editions

NOTE: This is only the concept of the project

In modules/corelib/ui/uiwidget thats the code necessary

UICallbacks = {
  callbacks = {}
}

function UICallbacks:createCallback(classname, fromcall, callback, id)
 local id

  for functionName, _ in pairs(_G[classname]) do
      if fromcall== functionName then

          if not self.callbacks[classname] then
            self.callbacks[classname] = {}
            self.callbacks[classname][fromcall] = {}
          end
          id = id or #self.callbacks[classname][fromcall] + 1
          if not self.callbacks[classname][fromcall][id] then
            self.callbacks[classname][fromcall][id] = callback
          end
      end
  end
return true
end

function UICallbacks:executeCallbacks(classname, callname, ...)
    local delete = delete or false
    local id = id or false
    for callbackId, callbackFunction in pairs(self.callbacks[classname][callname]) do
        if not id then
          callbackFunction(...)
        elseif id and callbackId == id then
          callbackFunction(...)
          return true
        end
    end
end

An example of where we can use the code
In modules/corelib/ui/uiminiwindowcontainer thats the code necessary

function UIMiniWindowContainer:onDrop(widget, mousePos)
  if widget:getClassName() == 'UIMiniWindow' then
    local oldParent = widget:getParent()
    if oldParent == self then
      return true
    end

    if oldParent then
      oldParent:removeChild(widget)
    end

    if widget.movedWidget then
      local index = self:getChildIndex(widget.movedWidget)
      self:insertChild(index + widget.movedIndex, widget)
    else
      self:addChild(widget)
    end

    UICallbacks:executeCallbacks(self:getClassName(), "onDrop", widget)
    self:fitAll(widget)
    return true
  end
end

And then to create calls:

  UICallbacks:createCallback('UIMiniWindowContainer', 'onDrop', function(widget) print("TESTING") end, 1)

The structure will look like this:

callbacks = {
  ['UIMiniWindow'] = {
    ['create'] = {functionX,},
    ['close'] = {functionX, functionT, functionP},
  },
  ['UIMiniWindowContainer'] = {
    ['onDrop'] = {functionX, functionT},
    ['create'] = {functionK, functionZ}
  },

 .
 .
 .

}
