Introduction

Unit Info Panels is an UI-Frame Resource, extending the default warcraft 3 UI. It upgrades the single Unit selection Frame into a Book with Pages. This only includes the normal view when the unit is not training, nor transporting.

Has a Lua and (v)jass version.
Requires Warcraft 3 V1.31 or higher.

Features

One can add additional custom Pages, showing other infos about the current Unit.
The pages also can contain interactive UI.
Each player can only see one page at the same time, that page doesn't have to be the same for them.
The current seen Page can be changed using up and down Buttons.
Includes a Framework to setup a Tooltiptext.
Probably one also don't want any unit be able to have access to all Pages. Therefore they can have a conditionfunction which prevents switching to it under such unwanted circumstances.
Supports using non-SimpleFrames you have to use SetUnitInfoPanelFrame, these non simpleframes don't become children of the UnitInfoPanels.

How to install


First you have to export and import the 2 Files in the demo map (using the export all Files function can bug in older Editor Versions).

war3mapImported\UnitInfoPanels.fdf
war3mapImported\UnitInfoPanels.toc
Now you copy UnitInfoPanels (trigger editor) into your map
Done.

Lua

(v)jass


Lua API
Code: 
AddUnitInfoPanel(frame, update[, condition])
    frame is the containerPanel, update a function(unit) that runs every updateTick, condition is a function(unit) that returns true or false it is used to prevent rotating to this panel.
AddUnitInfoPanelEx(update, condition)
    wrapper for AddUnitInfoPanel, it creates and returns a new frame

SetUnitInfoPanelFrame(frame)
    makes a non SimpleFrame share visibility with the last Added InfoPanel, supports only one Frame per InfoPanel
SetUnitInfoPanelFrameEx()
    wrapper SetUnitInfoPanelFrame creates and returns a new empty Frame

UnitInfoPanelAddTooltipListener(frame, code)
    detects if this frame is visible if it is call the given function which should return a text which is the now wanted tooltipText.

UnitInfoCreateCustomInfo(parent, label, texture, tooltipCode)
    return createContext, infoFrame, iconFrame, labelFrame, textFrame
UnitInfoGetUnit([player])
    returns & recacls the current selected Unit
    without a player it will use the local player.
 
function UnitInfoPanelSetPage(newPage, updateWanted)
    ignores conditions, newPage can be "+" or "-" or a frame

local AutoRun = true -- (false) call InitUnitInfoPanels()
Bounty Panel example in Lua. It creates 2 custom Unit Infos that display the gold and Lumber bounty on kill. This Panel can only be changed to when the owner of the current selected Unit gives bounty.
Lua: 
-- Shows how much gold and Lumber bounty one gets when slaying an unit
do
    local realFunction = InitUnitInfoPanels
    local lumberText, goldText, parent
    local createContext, infoFrame, iconFrame, labelFrame, textFrame
    local function Init()
        -- create a new Unit Info Panel, this panel can only be shown when the current selected unit's owner gives bounty
        parent = AddUnitInfoPanelEx(function(unit)
            local min, max
            min = BlzGetUnitIntegerField(unit, UNIT_IF_GOLD_BOUNTY_AWARDED_NUMBER_OF_DICE) + BlzGetUnitIntegerField(unit, UNIT_IF_GOLD_BOUNTY_AWARDED_BASE)
            max = BlzGetUnitIntegerField(unit, UNIT_IF_GOLD_BOUNTY_AWARDED_NUMBER_OF_DICE) *BlzGetUnitIntegerField(unit, UNIT_IF_GOLD_BOUNTY_AWARDED_SIDES_PER_DIE) + BlzGetUnitIntegerField(unit, UNIT_IF_GOLD_BOUNTY_AWARDED_BASE)

        end,
        function(unit) return IsPlayerFlagSetBJ(PLAYER_STATE_GIVES_BOUNTY, GetOwningPlayer(unit)) end)
        -- define locals
        
        -- create a new custom Info and load all created frames into the locals
        createContext, infoFrame, iconFrame, labelFrame, textFrame = UnitInfoCreateCustomInfo(parent, " Gold:", "UI\\Widgets\\ToolTips\\Human\\ToolTipGoldIcon", function(unit)
        -- this function returns the text shown inside the tooltip when this UnitInfo is mouse hovered.
            local min, max

            return "Bounty Gold: "..min.." - "..max
            .."\nWhen an unit owned by you kills this unit, you gain this amount of Gold.\nOnly unallied unit give bounty."
        end)
        local prevIcon = iconFrame
        goldText = textFrame
        BlzFrameSetPoint(iconFrame, FRAMEPOINT_TOPLEFT, BlzGetFrameByName("SimpleHeroLevelBar", 0), FRAMEPOINT_BOTTOMLEFT, 0, -0.001)

            .."\nWhen an unit owned by you kills this unit, you gain this amount of Lumber.\nOnly unallied unit give bounty."
        end)

The (v)jass API.
Code: 
UnitInfoGetUnit(player p) -> unit
    returns & recacls the current selected Unit, unneeded in given actionfunctions
AddUnitInfoPanel(framehandle frame, code update, code condition)
    frame is the containerPanel, update a function() that runs every updateTick, condition is a function() that returns true or false it is used to prevent rotating to this panel.
    it is suggested to use UnitInfoUnit inside this functions
AddUnitInfoPanelEx(code update, code condition) -> framehandle
    wrapper for AddUnitInfoPanel, it creates and returns a new frame
SetUnitInfoPanelFrame(framehandle frame)
    makes a non SimpleFrame share visibility with the last Added InfoPanel, supports only one Frame per InfoPanel
SetUnitInfoPanelFrameEx() -> framehandle
    wrapper SetUnitInfoPanelFrame creates and returns a new empty Frame
UnitInfoPanelAddTooltipListener(framehandle frame, code func)
    detects if this frame is visible if it is call the given function which is expected to set string UnitInfoTooltipText to the now wanted tooltipText.
UnitInfoCreateCustomInfo(framehandle parent, string label, string texture, code tooltipCode) -> integer
    returns createContext
    you can get the frames over globals UnitInfoInfoFrame, UnitInfoIconFrame, UnitInfoLabelFrame, UnitInfoTextFrame
UnitInfoPanelSetPage(integer newPage)
    ignores conditions, using 0 will change to next page and -1 previous page
UnitInfoPanelSetPageByFrame(framehandle newPage, boolean updateWanted)
    searches the index of newPage and calls UnitInfoPanelSetPage when found
A vjass Demo contained by the Demo Map. It shows 8 abilities the current selected Unit got. (Lua also got that, but what use would it have to show the same example twice, on this page).

The demo Panels share a set of functions which you could copy paste, but change the content of this functions to fit you wanted Pages.
This would be private function condition, private function update, private function At0s, private function init_function.
init_function is the default vjass helper init, it starts a timer so At0s runs as soon the game started.
At0s creates the page and setups it.
condition is a simple function that tells, if one can change to this page. Beaware that this runs async.
update is called every update Tick by the main System, you use this if the displayed infos change based on the current situation.
tooltipAction is called when in the main system's update Tick the tooltip detector is hovered. Beaware that this runs async and every update Tick as long as hovered.
JASS: 
library SkillPanel initializer init_function requires UnitInfoPanels
