(API) Tabs

Information

The tabs object functions a lot like the tabs you would find in an internet browser.

Example Use

local frame = loveframes.Create("frame")
frame:SetName("Tabs")
frame:SetSize(500, 300)
frame:CenterWithinArea(unpack(demo.centerarea))
         
local tabs = loveframes.Create("tabs", frame)
tabs:SetPos(5, 30)
tabs:SetSize(490, 265)
         
local images = {"accept.png", "add.png", "application.png", "building.png", "bin.png", "database.png", "box.png", "brick.png"}
         
for i=1, 20 do
    local image = "resources/images/" .. images[math.random(1, #images)]
    local panel = loveframes.Create("panel")
    panel.Draw = function()
    end
    local text1 = loveframes.Create("text", panel)
    text1:SetText("Tab " ..i)
    text1:SetAlwaysUpdate(true)
    text1.Update = function(object, dt)
        object:Center()
    end
    tabs:AddTab("Tab " ..i, panel, "Tab " ..i, image)
end

Event Callbacks

The tabs object has no unique event callbacks.

Methods

AddTab

Add a tab to the object. Each tab must have a base object. The base object is the second argument provided.

The last two arguments of this method are optional and are used to specify callback functions for the tabbutton object that will be created after calling this method. More specifically, these two callbacks are OnOpened (called when the tab button becomes active or is "opened") and OnClosed (called when the tabbutton becomes inactive or is "closed"). The tabbutton object will provide itself as an argument whenever it calls one of these callbacks.
