Loveframes Text:GetLines()

[riidom]

Hi, I have a problem with the GetLines() function from the text object. It returns always nil.

Code: Select all

function Node:initialize(px, py, pw, ph)
	
  local SliW = 5 -- width of slider buttons
  local MinW = 50 -- minimum width of whole node
	
  -- Init of base and sub-elements
  local base = loveframes.Create("panel")
  base:SetPos(px, py):SetSize(pw, ph)
  base:SetProperty("RightEdgeX", px + pw)
  --
  local text = loveframes.Create("text", base)
  text:SetPos(SliW + 1, 0):SetSize(pw - (SliW + 1) * 2, ph):SetMaxWidth(pw - (SliW + 1) * 2)
  text:SetText("Objects (blablabla)")

  --more stuff

  -- update pos&size of all elements after resizing the base and having new amount of lines
  function base:Update(dt)
    --print(text:GetLines())
    local h
    if text:GetLines() then h = text:GetLines() * 10 else h = base:GetHeight() end
    local x, y, w = base:GetX(), base:GetY(), base:GetWidth()
    base:SetHeight(h)
    leftResizer:SetHeight(h)
    rightResizer:SetX(w - SliW):SetHeight(h)
		
    --text:SetPos(SliW + 1, 0):SetSize(w - (SliW + 1) * 2, h):SetMaxWidth(w - (SliW + 1) * 2)
    text:SetPos(SliW + 1, 0):SetMaxWidth(w - (SliW + 1) * 2)
  end
end

this results in , to not get an error I checked for nil and instead use the default height.

So am I using GetLines somehow wrong? Here is the full code in a .love if anybody is interested (per se not interesting yet, it's pretty much a stub, I would like to solve this problem first, before I go on) What you can do, is grabbing the left and right borders of the nodes and change the width by dragging.

Well I don't know much about this library but i do know that GetLines() in text.lua will always return nil because self.lines doesn't exist anywhere in the object creation other then inside GetLines().

line 667 of LoveFrames/objects/text.lua

Code: Select all

function newobject:GetLines()

	return self.lines
	
end

there is a local lines inside of SetText() but its never used

on line 373 of LoveFrames/objects/text.lua

Code: Select all

	local lines = 0

Oh well, thanks for looking in the source, I could have get the idea to do so myself
It seems to be very recent and not fully done, on top of file it says:

Code: Select all

-- note: the text wrapping of this object is experimental and not final

Good there is a lot of other stuff for me to add as well in meantime.
